Newbie question clipboard

[Thomas Hehl]

Please forgive a newbie. I have extensive development background, but am new to wine and, though I've used VB a lot, am somewhat new to API programming.

I have an error while running Pagemaker 7.0 and try to paste text from the clipboard that I put into the clipboard from another app. I tried running with +relay and got a bunch of stuff. I tried +msgbox to find a trace for the message box that's created, but that didn't seem to work for some reason.

At any rate, here's the dump and my questions:

0009:Ret  user32.OpenClipboard() retval=00000000 ret=00439e04

1. On the line: Call user32.GetClipboardData(00000001) ret=00439e26, what does the ret mean? Isn't the return value posted later in the log?

2. I haven't found a user32.c and have found many, many hits in the source for GetClipboardData that I'm trying to sort through? How do I find the source code for that call?

3. Since I haven't found that, I can't verify the type being passed it. It should be CF_TEXT, but without the source, how do I find the value for that constant?

4. It looks like GetClipboardData returned a handle with a value of 796d604a, then it immediately locks this. It then turns around and unlocks it without doing anything, then never uses this handle again. Is this right?

5. After all that, it appears to allocate and unallocate memory and then re-open the clipboard. Is it doing this because the last time it tried it got nothing? Then, because it returned 0000000, it gave up and generated an error?

Thanks.
