Binary Compatiblity
22-Jul-2005
Microsoft has released a free LibCheck tool that allows you to compare two versions of an assembly, and determine the differences. The tool reports the differences as a combination of 'removed' and 'added' APIs. The tool is limited to looking only at APIs (i.e, it can't check for behavioral changes), and only compares public differences, or changes which are deemed to be 'breaking'. The tool can be used to quickly determine what has changed between one version of your assembly and another, and can help ensure that you won't introduce any breaking changes to clients of your assembly. Instructions and intended use of the tool are described in the 'libcheck tool specification' document with the zip file.
This was a feature I always was missing. VB6 had this, VS.NET didn't. Thanks MS.
AsyncHelper for VB.NET
21-Apr-2005
I received a mail today from Rolf Gasber asking me whether I could help him with a VB.NET version of the AsyncHelper which I used in an earlier post. Here it is:
Public
Class AsyncHelper Private Delegate Sub DynamicInvokeShimProc( ByVal d As [Delegate], _ByVal args() As Object ) Private Shared _dynamicInvokeShim As _
New DynamicInvokeShimProc( AddressOf DynamicInvokeShim) Private Shared _dynamicInvokeDone As _
New AsyncCallback( AddressOf DynamicInvokeDone) Public Shared Sub FireAndForget( ByVal d As [Delegate], _
ByVal ParamArray args() As Object )
_dynamicInvokeShim.BeginInvoke(d, args, AddressOf _
DynamicInvokeDone, Nothing )
End Sub Private Shared Sub DynamicInvokeShim( ByVal d As [Delegate], _
ByVal args() As Object )
d.DynamicInvoke(args)
End Sub Private Shared Sub DynamicInvokeDone( ByVal ar As IAsyncResult)
_dynamicInvokeShim.EndInvoke(ar)
End Sub
End

WaitCursor
10-Feb-2005
For a long time I thought that I only had to set the Cursor.Current to a WaitCursor before a long running operation, the .NET runtime would reset it back to the Default cursor. Turns out that this is only true when the mouse is moved. Bummer.
// Cursor.Current are automatically reset to Default when the
// mouse is moved and the application is idle!
Cursor.Current = Cursors.WaitCursor;
// mouse is moved and the application is idle!
Cursor.Current = Cursors.WaitCursor;
The solution for this problem is very easy. I created a helper class called WaitCursor which set the Cursor.Current and restores it to the original value when it it disposed.
public
sealed
class WaitCursor : IDisposable {        
 private Cursor _prev;
 public WaitCursor(){
   _prev= Cursor.Current;
   Cursor.Current = Cursors.WaitCursor;
 }
 publicvoid Dispose(){
   Cursor.Current =_prev;
 }
}
 private Cursor _prev;
 public WaitCursor(){
   _prev= Cursor.Current;
   Cursor.Current = Cursors.WaitCursor;
 }
 publicvoid Dispose(){
   Cursor.Current =_prev;
 }
}
I create the instance of the WairCursor class inside a using statement. This will automatically call the Dispose() method when it goes out of scope.
Micro-ISV

Microsoft has invented a new name Micro-ISV, which are software companies that are comprised of only one person. So, I'm a Micro-ISV. Planning to launch my product this year. I hope to succeed.
Dispose Modal WinForm Dialogs
12-Dec-2004
There is a difference in disposing Modal and Non-Modal forms. In a training I gave last week I noticed that even experienced developers didn't know that Modal Dialogs don't dispose automatically, Non-Modal do.
private
void
buttonShowNonModalForm
(
object
sender
, System.EventArgs e){
 new TestForm().Show();
}
privatevoidbuttonShowModalDialog(objectsender, System.EventArgs e){
 new Form2().ShowDialog();
}
 new TestForm().Show();
}
privatevoidbuttonShowModalDialog(objectsender, System.EventArgs e){
 new Form2().ShowDialog();
}
The solution to this problem is very simple by creating the Form instance within a using block. This will dispose the Form when it is closed.
private
void
buttonShowModalDialog
(
object
sender
, System.EventArgs e){
 using(TestForm f =new TestForm()){
   f.ShowDialog();
 }
}
 using(TestForm f =new TestForm()){
   f.ShowDialog();
 }
}
An alternative solution uses a try/finnaly. Personally I prefer the previous, it is easier to read and write.
Best CV ever!

C# HandleWhiteSpace Add-In
23-Sep-2004
The C# code editor in Visual Studio.NET 2003 does not handle whitespaces automatically like the VB.NET code editor does. This Add-In solves this problem by adding the 'Handle WhiteSpace' menu option to the Visual Studio.NET 2003 Tools menu. This option formats the C# code of the active code editor. This includes:
- Space before: method declaration parentheses, method call parentheses, statement parentheses, braces and brackets
- Space after: comma and semicolon
- Space around: operators
- Double space
