Hi,
I got the following code in WinDbg through bp UpdateWindow. However, when using wida to edit it, it cannot find the code. Same in hiew. I thought perhaps the 7's should be 0's, but that didn't help. Any thoughts on how I can edit it? Thanks.

It looks like you have landed in the heart of one of the system API's. If you used softice to get here, you may want to use the F12 key a few times once landing to get back to application code.

If you really want to edit it, try looking at the file user32.dll, but I don't think you want to do that.

Oh I see, thanks. Does anyone know how to f12 in WinDbg?

Ah, WinDbg... You could possibly examine the stack for return addresses to your app code? (assuming you know the valid addresses for it)
