Kentico 8.1 - Custom Upload Form Control [Solved to support custom table to store image/binary stream data]

Leave a Comment
Kentico is a powerful CMS engine that allow you to developed portal very fast. But when you have a really big data such as (10,000 above), you may need to think a different way to store the data(Not put all document as a Page Menu Item).

I have heard kentico have test their product for 100K document. But from my experience using shared server, it is cause a lot of painful if you want to expand the node in your page module, and even very slow to load the data.(That is my situation).

So after all, I have decided to developed a "Custom Upload FormControl" to make Custom table support for upload files/media. This implementation is quite tricky because the custom formcontrol just store link to custom table field and it will store the image into media library folder. Look at the flow below :
  1. User/admin upload image using custom formcontrol
  2. Custom formcontrol check folder in media library, if not exist, create media library folder.(Each user will have their own folder so in future if you want to limit the folder size, you can modified the code to check folder file is user have exceed their storage - quite cool ha B-) 
  3. Custom form control will save link to custom table
I will share the code here, and you can test by your self. 
Before That you need to create Media Library name "UserMedia".

Note : This is just example only, the code may have a bug. Use it at your own risk.

ASCX page

<cms:Uploader ID="uploader" runat="server" OnOnDeleteFile="uploader_OnDeleteFile1" OnOnUploadFile="uploader_OnUploadFile1" />

Adding Dynamic Control from Code Behind - Dropdown, Listbox, Checkbox etc

Leave a Comment
This tutorial / example show how you can add dynamic control from code behind. This example not only limit to Dropdown, Listbox and Checkbox  controls, but you can use this example for any controls. The only things that you need to understand the process.

Step By Step

  1. Create one new project name DynamicControls
  2. Add One web form or web form using master page if you use default template master page.
  3. Copy paste code below respectively.(Note: im using default masterpage template from VS2010)

ASPX code

    <h3>
        This is Dynamic Control Tutorial
    </h3>

    <asp:Button ID="Button1" runat="server" Text="Add ListBox To Panel"
        onclick="Button1_Click" />
    <br />
    <asp:Button ID="Button2" runat="server" Text="Add Dropdown To Panel"
        onclick="Button2_Click" />
    <br />
    <asp:Button ID="Button3" runat="server" Text="Add CheckBox To Panel"
        onclick="Button3_Click" />
    <br />

    <asp:Panel GroupingText="Dynamic Control Added" ID="PanelToAddDynamicControl" runat="server">
    </asp:Panel>

Await in Catch and Finally

Leave a Comment
This is just a brief note to publicize a coming improvement to the async language support.

With the new compilers, changes to the C# language (e.g., async/await) are easier than they used to be. One improvement that is coming is the use of await in catch and finally blocks. This enables your error-handling/cleanup code to be asynchronous without awkward code mangling.

For example, let’s say that you want to (asynchronously) log an exception in one of your async methods.

The natural way to write this is:

 
try
{
  await OperationThatMayThrowAsync();
}
catch (Exception ex)
{
  await MyLogger.LogAsync(ex);
}


And this natural code works fine in Visual Studio “14”. However, the currently-released Visual Studio 2013 does not support await in a catch, so you would have to keep some kind of “error flag” and move the actual error handling logic outside the catch block:
 


Exception exception = null;
try
{
  await OperationThatMayThrowAsync();
}
catch (Exception ex)
{
  exception = ex;
}
if (exception != null)
  await MyLogger.LogAsync(exception);




This is only a simple example; in real-world code, this can get ugly rather quickly!

Register winform app HotKeys - C#

Leave a Comment
Hotkey is a very useful shortcut for complex application. Sometimes we build application with much feature include in it hence will result of bad experience of end user because the feature dont have the shortcut keys.

Here is a sample to add shortcut keys or hotkeys for winform app in C# code.

GlobalHotkeys.cs

 
using System;
using System.Windows.Forms;
using System.Runtime.InteropServices;


namespace Hotkeys
{
    public class GlobalHotkey
    {
        private int modifier;
        private int key;
        private IntPtr hWnd;
        private int id;


        public GlobalHotkey(int modifier, Keys key, Form form)
        {
            this.modifier = modifier;
            this.key = (int)key;
            this.hWnd = form.Handle;
            id = this.GetHashCode();
        }

        public bool Register()
        {
            return RegisterHotKey(hWnd, id, modifier, key);
        }

        public bool Unregiser()
        {
            return UnregisterHotKey(hWnd, id);
        }

        public override int GetHashCode()
        {
            return modifier ^ key ^ hWnd.ToInt32();
        }

        [DllImport("user32.dll")]

        private static extern bool RegisterHotKey(IntPtr hWnd, int id, int fsModifiers, int vk);

        [DllImport("user32.dll")]

        private static extern bool UnregisterHotKey(IntPtr hWnd, int id);

    }

}

        {
            WriteLine("Hotkey pressed!");
        }

        protected override void WndProc(ref Message m)

How to specify WhereCondition in Transformation - Nested Control - kentico 8, 7, 6

Leave a Comment
Before this i wonder how to pass some where condition in transformation repeater. So i ask the kentico guys and he give me a solution which i think i can share to the others.

So in your transformation you can specify the <script runat="server"></script> element. This is where you can pass the where condition.

Let see the example :

Transformation Code


<cms:queryrepeater id="repItems" ... DelayedLoading="true" ... />

<script runat="server">
protected void Page_PreRender(object sender, EventArgs e)
{
queryrepeater.WhereCondition= "NodeAliasPath LIKE '"+(string)Eval("NodeAliasPath")+"'";
queryrepeater.ReloadData(true);
}
</script>

Note : queryrepeater dont have DelayedLoading properties, use DataBindByDefault="false" instead.

Javascript Clock example

Leave a Comment
This example show how to insert clock on the website which is not static clock, but like a digital clock.

Script for Creating Clock

 <script type="text/javascript">
        function updateClock() {
            var currentTime = new Date();
            var currentHours = currentTime.getHours();
            var currentMinutes = currentTime.getMinutes();
            var currentSeconds = currentTime.getSeconds();

            // Pad the minutes and seconds with leading zeros, if required
            currentMinutes = (currentMinutes < 10 ? "0" : "") + currentMinutes;
            currentSeconds = (currentSeconds < 10 ? "0" : "") + currentSeconds;

            // Choose either "AM" or "PM" as appropriate
            var timeOfDay = (currentHours < 12) ? "AM" : "PM";
            // Convert the hours component to 12-hour format if needed
            currentHours = (currentHours > 12) ? currentHours - 12 : currentHours;
            // Convert an hours component of "0" to "12"
            currentHours = (currentHours == 0) ? 12 : currentHours;
            // Compose the string for display
            var currentTimeString = currentHours + ":" + currentMinutes + ":" + currentSeconds + " " + timeOfDay;
            // Update the time display
            document.getElementById("clock").firstChild.nodeValue = currentTimeString;
            //return currentTimeString;
        }
    </script>


Call the clock on body load

<body onload="updateClock(); setInterval('updateClock()', 1000 );">


Div element for clock

   <div id="clock" style="font-size:larger; font-family:Verdana;">
    </div>

Kentico 7 - Get Specific document information

Leave a Comment
This post will show how to get specific document information using Transformation In Kentico 7.

Note : i have tested this method in kentico 7 only, donno if the other version will work.

You can refer this link to create new transformation method

Example :

You can use this method in your transformation let say you create new repeater and want to show the parent name of the binding document type data. In this scenario, the document type store under different parent node.

       public string getDocumentInfo(string documentID, string parentProperties)
        {
            TreeProvider tree = new CMS.DocumentEngine.TreeProvider(CMSContext.CurrentUser);
            TreeNode Node = DocumentHelper.GetDocument(Convert.ToInt16(documentID), tree);

            if (Node != null)
            {
                switch (parentProperties)
                {
                    case "NodeID": return Node.NodeID.ToString();
                    case "NodeAliasPath": return Node.NodeAliasPath;
                    case "NodeName": return Node.NodeName;
                    case "NodeAlias": return Node.NodeAlias;
                    case "NodeClassName": return Node.NodeClassName;
                    case "NodeParentID": return Node.NodeParentID.ToString();
                    case "NodeLevel": return Node.NodeLevel.ToString();
                    default: return string.Empty;
                }
            }
            else
            {
                return "Current UserInfo :" + CMSContext.CurrentUser + " Node is null";
            }
        }


How to use

getDocumentInfo(Eval("NodeParentID").ToString(),"NodeName")

SD Card Problem There May Be something wrong with this SD Card, Insert it into a computer to fix it.[SOLVED]

Leave a Comment


SD Card Problem
There May Be something wrong with this SD Card, Insert it into a computer to fix it.

When you use the windows phone that support SD card feature, sometime you will face this problem. Me myself also was faces this problem before. So i want to share the solution to fix this problem.

Symtoms

When you attempt to open, delete or rename a file or folder using Windows NT Explorer, File Manager or a command prompt, you may receive one of the following error messages:

<drive>:\<folder> is not accessible
The file or directory is corrupt and non-readable.The file or directory is corrupt and non-readable. The file or directory \<folder> is corrupt and unreadable.
Please Run the Chkdsk utility.

Cause

This behavior can occur if the file, folder or file system index (Master File Table [MFT] or File Allocation Table [FAT]) is damaged.

Solution :


  1. Click Start, and then click Run.
  2. In the Open box, type chkdsk /f <drive>:, where <drive> is the letter of the drive on which the damaged file, folder or file system index exists.
  3. Click OK.

Note : If the hard disk is large, Chkdsk may take several minutes to several hours to complete.

  1. Login to the SQL Server using windows authentication.
  2. Right click on the SQL Server node >> properties.
  3. Go to Security tab.
  4. Under SQL Authentication choose SQL Server and Windows Authentication mode.
  5. Click Ok Button.

  7. Restart SQL Server instance.
  8. Try to login again using your login information.
  9. Done.

[SOLVED]Windows Phone 8 - Duplicate Files

Leave a Comment
Windows Phone users around the world have reported that their photos, videos or music automatically create multiple copies of themselves. When you delete a single copy, the rest of them don’t open. There have been ongoing discussions spanning across multiple Windows forums pertaining to the issue, but a real solution hasn’t been found yet.

This bug was probably introduced after GDR 2 update for Windows Phone and usually affects devices with external SD Card support. Some users have suggested that it might be because of the syncing method used (Windows Phone 8 currently uses 4 different ways to import content into the phone: The Windows Phone Modern App, the Windows Phone app for Desktop, using Windows Media Player to sync its contents, or using File Explorer to import items via drag and drop or by copying files). But switching to a different method of syncing doesn’t seem to work for everyone.

Also, re-syncing usually involves emptying the entire media library on the phone, formatting the SD Card and then, and then recopying the music, videos and photos back to the card over again. And even then, you’re not sure the duplication won’t happen again. It’s a lot of time consuming re-work for something that doesn’t even offer a guaranteed fix to the problem.

Well, we have tried out several ways to eliminate duplicates from the Windows Phone library without having to delete an entire media collection. And after a few failed attempts, one of them was successful. It has worked for us and we’re quite certain that it’ll work for you too.

Why does Windows Phone create duplicate media files?

Only the folks over at Microsoft may be able to answer that. We can only make a guess that it occurs when you try to copy / sync an item which is already present on the phone. The phone’s media library is probably maintained by a file, which keeps a tab of all the music, videos and photos present on your SD Card. It would also keep a record of metadata, like song artist, album and so on. In other words, this library file links the information you see on your phone (for example, in the Music + Videos hub) to the files on your SD Card. The file also makes it possible to browse through your media collection without an actual file manager.

When this file gets corrupted, it creates multiple attributes for the same file. So, when you delete a particular copy on your phone, it deletes the actual file present on the SD Card. Now, all the other references to the same file still exist, but the file has been deleted. This might be the reason why the other copies fail to open a file when one copy has been deleted.

SOLUTION

Even though you see multiple copies of media on your phone, Windows Phone does not create multiple copies of files on your Windows Phone. The problem thus lies in a corrupted library file. Unfortunately, there is no way to edit or replace this file. Here, we’ll rather try and let Windows Phone recreate the library from scratch, and this time, without the duplicates.

Note: If you have upgraded to Windows Phone 8.1 and have apps installed on the SD card, the following steps might corrupt these apps. So, make sure you move all your apps to phone memory before proceeding any further. Go to Settings >> Storage Sense >> Tap on SD card >> apps+games. Tap on the selection button at the bottom and check “select all”. Finally, tap on the move button to transfer the apps to phone memory. After successfully completing all the steps, you can transfer the apps back to the SD card if you want to.

Here’s what you should do:

  1. Remove the SD Card from your phone and access it on your computer through a suitable card reader. Once you plug in the card, you should notice only single copies of media files.
  2. Open File Explorer and enable view for hidden files on your computer (Open Folder and Search options >> View tab >> Select Show Hidden files, folders and drives).
  3. Other than media folders (like Music, Videos, etc.), you should see two additional folders labeled WPSystem and System Volume Information on the SD Card. Delete the WPSystem folder. System Volume Information folder can’t be deleted directly on Windows. For deleting it, you need to run a few commands in an elevated (Admin) Command Prompt.Update:  Some of our readers have pointed out that the WPSystem and System Volume Information folders remain hidden even after enabling the “Show Hidden files, folders and drives” option. It appears that you also have to uncheck another option in order to view these folders. Go to Folder and Search options >> View tab >> Uncheck “Hide protected operating system files” option >> Click OK. You will now be able to see both folders in File Explorer.
  4. Note the drive letter assigned to your SD Card.
  5. Go to Start and type “CMD” in the Search box.
  6. Right click on the result (Command Prompt) and choose “Run as Administrator”. Now, execute the following commands one after the other, assuming H is the drive letter assigned to the SD Card:
    - H:
    - attrib -s -h /S /D
    - attrib -r /S /D
    - rd "System Volume Information" /S
    - And enter Y to confirm the delete operation.(Ignore message if the error cannot fine "System Volume Information - because that folder not exist, the action only if you sdcard have System volume information folder)
  7. Now, turn on your Windows Phone and connect it to the computer (without the SD Card).
  8. Navigate to your Phone storage and ensure that there are no references of files from the SD Card. Usually you’d save your photos, videos and music on the SD Card, so the Phone Storage should not display any media file. You may transfer everything from phone storage to sdcard
  9. Disconnect both the phone and SD Card from your computer and insert the card back onto the phone.
  10. Power on the Windows Phone and let it rebuild its library file.


Hopefully, by following these steps, you would have successfully got rid of duplicate file copies. If you found this article helpful, don’t forget to share it with other fellow Windows Phone users.


NOTE : 

  1. Do not copy Camera Roll Folder in memory card using card reader. After rebuild done, then you may copy the Camera Roll Files in the folder using their File Explorer. 
  2. This method sometime work sometime didnt, you need to try and retry again because in my experience the duplicate sometime exist in Folder A, but not Exist in Folder B. If this is the situation(after step 10 done). Then you can plug in USB cable and find the duplicate folder. Delete the folder(Make Sure the Folder cannot see in the photos app in your phone after delete it- If you still see the photo and folder after delete using File explorer, you may wait for a while until the folder dissappear or unplug the cable usb). Then add the folder again using the File Explorer
  3. Make Sure you put files in the correct folder which music files in the Music Folder, image files in Picture Folder and video files in the Videos Folder
  4. This solution works for my Nokia Lumia 1520 . It is soo embarrassing to Microsoft which is cannot build the OS which cannot verify the files before listing the files to end user. Boooo... Windows smart phone is not the "SMART" phone, but "DIFFICULT" phone. End.
