Core JavaScript files in the Microsoft AJAX Library

The JavaScript files provide client side functionality for your web pages. Three JavaScript files are stored as resources in the System.Web.Extensions assembly.

At runtime, the HTTP handler ScriptResourceHandler loads the files, caches them for future use, compresses them, and sends them to the web browser when they’re requested:

* MicrosoftAjax.js, contains most of the Microsoft AJAX Library’s functionality, the browser compatibility layer, the core JavaScript classes, and the Base Class Library.

* MicrosoftAjaxTimer.js, contains classes to support the Timer server control. This control enables you to update either part of or an entire web page at regular intervals,

* MicrosoftAjaxWebForms.js, contains classes to support partial page rendering, this functionality allows portions of a page to be updated asynchronously.

Visual Studio - Search order for assemblies

Search order for assemblies when building a project of a solution in Visual Studio:

* Files from the current project indicated by {CandidateAssemblyFiles}.
* $(ReferencePath) property that comes from .user/targets file.
* $(HintPath) indicated by reference item.
* Target framework directory.
* Directories found in registry that uses AssemblyFoldersEx Registration.
* Registered assembly folders, indicated by {AssemblyFolders}.
* $(OutputPath) or $(OutDir)
* GAC

If the desired assembly is found by HintPath, but an alternate assembly can be found using ReferencePath, it will prefer the ReferencePath to the HintPath one.

Visual Studio - Search order for assemblies

Visual Studio - Specify assemblies location by registry key

- Open registry by Regedit
- Search for following key (Depend on VS version use the correct number to point to this key in registry):
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\9.0\AssemblyFolders]
- Set the value of the key [AssemblyFolders] of type REG_SZ to the path of your assemblies.

Visual Studio - Specify assemblies location by registry key

to specify where Visual Studio search for the assemblies which you reference in your project

Unfortunately Visual Studio doesn't allow you to edit to reference assemblies, then you need to open the project file by a text editor and directly edit the ta and save the project file. When Visual studio detects the file change, it will ask you to reload the file.

Example:

<Reference Include="YourAssembly.dll">
<SpecificVersion>False</SpecificVersion>
<HintPath>C:\CommonAssemblies\YourAssembly.dll</HintPath>
</Reference>

to specify where Visual Studio search for the assemblies which you reference in your project

iPhone - Apple's NDA-protected license agreement changed in April 2010

The original clause stated:

3.3.1 — Applications may only use Documented APIs in the manner prescribed by Apple and must not use or call any private APIs.

The new version of 3.3.1 reads:

3.3.1 — Applications may only use Documented APIs in the manner prescribed by Apple and must not use or call any private APIs. Applications must be originally written in Objective-C, C, C++, or JavaScript as executed by the iPhone OS WebKit engine, and only code written in C, C++, and Objective-C may compile and directly link against the Documented APIs (e.g., Applications that link to Documented APIs through an intermediary translation or compatibility layer or tool are prohibited).

It means frustrating news for developers with lot more restrictions to develop applications on iPhone. Then developers can no longer use software like Novell's MonoTouch, Unity3D, or Ansca's Corona to develop iPhone applications, and tools like Appcelerator's Titanium and PhoneGap are looking uncertainty. Generally it restricts users from utilizing different programming languages, libraries, and tools.

Windows Phone 7 Series

During the Mobile World Congress 2010 in Barcelona, Microsoft revealed details of Windows Phone 7 Series
In a nutshell, Xbox Live games and Zune music are now features of Windows Phone 7. These phones arrive by holiday 2010 (may be it's too late).

With the specification requiring all Windows Phone 7 Series devices to feature three buttons, Back button, Start button and Search button. On the other hand, HTC released three new phones and proclaimed the company's commitment to Windows Phone 7 on Tuesday (Feb 16, 2010).

About hardware requirements, No mention has been made of the underlying hardware, although in one of the videos on the Series 7 YouTube page, a Qualcomm representative talks about its Snapdragon chip, a 1GHz ARM-based chip that currently powers Google’s Nexus One.

RollBack in VSS when you don't have rollback permission

When you don't have rollback permission, you can replace a version of file with the new version and keep the project running safely.

It's based on Visual Source Safe but the idea is simply general.

• Select the file in VSS Explorer.
• Check out the file using the Check Out command on the SourceSafe menu or by right clicking on the file and choosing the command from the context menu.
• Choose Show History from the Tools menu.
• To show the History of File, click OK.
• Select a file version which you want to back to and click on Get.
• In the Get dialog box, click OK.
• In response to the message asking whether to replace the checked out file, click on Replace.
• Click Close to quit the History of File dialog box.
• Use Check In command on the SourceSafe menu or from context menu which appears by right clicking.

VS 2008 - Microsoft.VisualStudio.DataDesign.SyncDesigner.SyncFacade.SyncManager Error

I experience the following error message when I wanted to get connected to a database on a SQL 2008 Express from a machine with a newly installed Visual Studio 2008.

When I tried "Add New Data Source" and after creating connection string at the time of proceeding to finalize the connection, the Error Message came up:

Could not load type 'Microsoft.VisualStudio.DataDesign.SyncDesigner.SyncFacade.SyncManager' from assembly 'Microsoft.VisualStudio.DataDesign.SyncDesigner.DslPackage.Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.

The simple solution which worked for me was installing VS 2008 SP1, at this moment it's available at:
