This is an internal wrapper around LoadString that makes no promises about double-null termination, etc. Don't make assumptions. Also, you need to keep the style of the original code when making changes. There was an empty line where you added the aforementioned pieced of code, and that empty line separates logically different pieces of the function. 1024 is a magic number and it needs to go. You're putting a limitation of 1024 length on HH_LoadString that didn't exist before. -- James Hawkins

Re: Test case for Bug 50 [Was: Bug 50]

On 2007-01-29, Duane Clark wrote: > GetTextExtentPoint32 > > For some examples in Wine, look at almost any control in comctl32. I was afraid somebody would answer that... Thanks for the quick reply, but that isn't exactly what I need. Here's the picture: when an application calls TextOut() for printing text, the usual (at least in my case) call sequence in Wine is TextOut() TextOutA() ExtTextOutA() ExtTextOutW() (the one I patched) GetTextExtentPointW() GetTextExtentPoint32W() (the wide-char version of the one you mentioned) GetTextExtentExPointW() WineEngGetTextExtentExPoint() (the one that actually gets the individual character widths) That is, at some point, TextOut() indirectly uses GetTextExtentPoint32() to get the dimensions, okay. But what I need is to check the text width *after* it was output by TextOut() -- in other words, after the function has returned, to see if it output the text properly. In Wine, I tried the trick of making ExtTextOutW() return the said value, and the tests passed without a hitch, which means the text is being properly justified. The problem is that such is not an acceptable way of doing things, and, to use Dan Kegel's words, that is not going to fly on Windows. To be a bit clearer, in my tests I do call GetTextExtent32() in order to compute the remaining white space for the justification part, and what I want to check is whether TextOut() understood it right or not. - Pedro.

Please help me debug wineserver
by Misha Koshelev 29 Jan '07

29 Jan '07

Hi, I am new to wine programming but have a fair amount of experience with C/C++ programming in general. I have recently decided to make the Vector NTI application work on Wine, and after overcoming quite a few installation difficulties by making an install shell script, I have run in to a problem that I have traced down to wineserver. This problem occurs after repeatedly changing folders in the Vector NTI "Open Molecule File" dialog, which does not use the standard open file Windows dialog (e.g., the "Open Shortcut" dialog in the same program works fine). Wineserver crashes with the following error message: wineserver: object.c:274: release_object: Assertion `obj->refcount' failed. On looking at the output of WINEDEBUG=+server, it seems that the "Vector NTI" thread is woken up, and then receives a USER_APC, at which time this crash occurs. I am including at the end of this message a wineserver gdb backtrace and the last few lines of the WINEDEBUG=+server output. If anyone sees anything that jumps out, I would appreciate your help. Thank you very much.
