C# SendMessage(...) question

[Nidhi]

Hi,

I am trying to write code to retrieve the small icon for an
application in C#. I am using SendMessage with WM_GETICON for this
purpose but the return value I get is 0. I don't understand this. Is
that expected? What am I doing wrong?
Any help would be appreciated. Here is the snippet of code that I am
using -

[DllImport("user 32")] public static extern int SendMessage(int
hwnd,int msg,int wparam,int lparam);

Process p = Process.GetProc essById(a.getPI D()); //the requisite process and
//the value returned is valid
IntPtr hwnd = p.MainWindowHan dle;
int icn = SendMessage((in t)hwnd,127,0,0) ; //I realize WM_GETICON = 127

Thanks!

Re: C# SendMessage(... ) question

Just try this :

int WM_GETICON = 0x7F;
int WM_SETICON = 0x80;
int ICON_SMALL = 0; //(16x16)
int ICON_BIG = 1; //(32x32)

IntPtr handle = pro.MainWindowH andle;
int IconHandle = SendMessage(han dle.ToInt32(),W M_GETICON,ICON_ SMALL -or- ICON_BIG,0);
Icon icn = Icon.FromHandle (new IntPtr(IconHand le));

Note : I can't retrieve the most icon's handle.
