Hang at PictureBox Code only with PocketPC Emulator -> Why?

Hi,

I am confussed. I am developing an application on PocketPC using C# with
VS.net 2003. It run fine on the compiled exe. It always do.

However, when run on the emulator, be it PocketPC version 2002 or 2003, it
always hang at the same code after I narrow down the issue.

f_Bitmap = new Bitmap(new MemoryStream(f_byteDataImage));
pictureBox.Image = f_Bitmap; // This is the line that got stucked

I am surprised that it supposed to be catched, rather than being freezed.
Any ideas? The f_byteDataImage is actually a complete JPEG buffer, just like
what being read from a file.

Thanks for taking your time to read. Hope there are someone kind enought to
point some light into my confussion.

Are you setting image from another thread?

If so, search this NG (link below) for "Control.Invoke" which you should use
to fix it.


Best regards,

Ilya

Small, 160x120, which work on the complied exe file, but not on the
emulator...
