Add SVN Revision Macro for Visual Studio 2005/2008

Objetive:
*Update automatically the revision number in the web.config file of a website in my project.
(I wanted to show the users looking at the remote server the revision they are looking at)
Environment
* SVN installed in my local (c:\svn)
* Remote Windows Server that updates the trunk every X minutes
* Make sure your web.config has a section like: (inside the configuration branch)

<appSettings>
  <add key="version" value="1.2." />
  <add key="revision" value="138" />
</appSettings>

Solutions:
I created two macros.... one for adding the revision number on demand (selected project and press of a button) and the other one will write it every time the build command is called.
for the macro code click Read more....

Ajax ControlToolKit and Firefox default button PostBack - Server Click Event

Symptoms:
Default button not does not fire when enter key is pressed using Firefox. (using the ajax ControlToolkit)
Fix:
add this property to the ASP button

UseSubmitBehavior="False"

So it looks like:
<asp:Button ID="btnSearch" UseSubmitBehavior="False" ValidationGroup="submit" runat="server" Text="Search"    CssClass="submitButton" OnClick="btnSearch_Click" />

"The problem wasn't that it didn't do a postback. That it did. What it didn't do was hit the server side event (the button click event)."

Demo of the Easy EasyObjects after the break :)

Easy EasyObjects

Is a modified version of Easy Objects.... and it's templates
that adds:

  • Nullable Types.... (no more int, only int?)
  • creates inserts,updates,deletes,selects as statics
  • adds the concept of VA (Value Objects) per table entry
  • adds non case sensitivity option on equal,like and not like operant


*note: only templates for C# available at the moment
and more to come....
i'm open to ALL kind of help, suggestions, complains etc..!
here is the flash demo if the modifications in use:

C# string comma separated to integer array

this C# function will convert an comma separated string in to an array of integers

private int[] commaStrToArray(string strIntComma)
{
string [] strArray;
strArray = strIntComma.Split(new char[] {','});
int [] intArray = new int [strArray.Length];
for (int i = 0; i < strArray.Length; i++)
intArray[i] = int.Parse(strArray[i]);
return intArray;
}
