Re: using CArchive Scot T Brennecke6-Jul-02 4:40 Scot T Brennecke 6-Jul-02 4:40  When someone asks for a code example on the MS newsgroups, I usually point them to CodeProject. But you're already here! This website is rife with example code.

Can anyone tell me what updates are available for this version as there seems to be a couple of bugs. For example, in the resource editor, if you try copying and pasting areas of a bitmap (for a treelist for example) between bitmap images, the pasted image is corrupted (mirrored and some other corruption). Thanks "The folly of man is that he dreams of what he can never achieve rather than dream of what he can." Re: Patching VC++ 4.2? Scot T Brennecke6-Jul-02 4:38 Scot T Brennecke 6-Jul-02 4:38  To my knowledge, MS did not issue service packs for DevStudio back then. The only updates that are available are later versions of DevStudio. IMO, VS 6.0 is the best thing they've produced yet. Unfortunately, you can't even get that from MS anymore, since they're trying to shove "dot net" down our throats. Scot Brennecke Software Developer VC++ MVP Re: Patching VC++ 4.2? thowra6-Jul-02 13:35 thowra 6-Jul-02 13:35  I've used VC 6.0 extensively but I actually like 4.2 now I'm using it. It's very lightweight compared to 6.0, the help is much faster - just uses a primitive window to display the help and examples rather than 6.0's MSDN type interface. Builds are really quick as well! There are some updates available for 4.2 but M$ being what they are, of the several available, one of the (apparently core) updates is unavailable from their site. I was just hoping someone might know of a bugfix for the resource editor amongst other things. Also, the updates as listed by M$ aren't exactly cleary described. For anyone interested, the updates are here: http://support.microsoft.com/default.aspx?scid=kb;EN-US;q156934 One of the ones I think I need is MSDEV42B.EXE which isn't available unfortunately.

Roger Stewart6-Jul-02 16:09 Roger Stewart 6-Jul-02 16:09  I searched Google for the exe name and found a link from a page to the microsoft ftp site. I was able to download the file, so it should work for you also: MSDEV42B.EXE Roger Stewart "I Owe, I Owe, it's off to work I go..." Re: Patching VC++ 4.2? thowra7-Jul-02 0:10 thowra 7-Jul-02 0:10  Thanks for that, I just went and got it. Wonder why all the others were working before and that one wasn't?

Mouse movement tracking? 6-Jul-02 2:36 6-Jul-02 2:36  what I am basically trying to do is: when I move the mouse over my transparent dialog with controls, the window should become opaque and when I move the mouse out of the window, the dialog should become transparent again. So far I have succeeded in handling only the event WM_MOUSEMOVE and I couldn't do the same with WM_MOUSELEAVE. I want to do somethink like the transparent window of Miranda IRC but I can't find yet any articles about mouse movement tracking (over dialogs with controls on them). How can I do that?

I've just started to look into GDI+. Everything works fine except the infamous function GdiplusShutdown() . The linker gives this message: TegeTest.obj : error LNK2001: unresolved external symbol _GdiplusShutdown@8 Debug/TegneTest.exe : fatal error LNK1120: 1 unresolved externals Error executing link.exe. I known this problem has been discussed some time ago, but has anyone found a remedy lately? I'm using Windows 98 and have downloaded the full SDK. In practice, is there a problem? It is always called at app. exit, in which case Windows cleans up everything anyway. Or...? Regards, Haakon S. Re: GDI+ shutdown problem Michael Dunn6-Jul-02 7:18 Michael Dunn 6-Jul-02 7:18  You're using the wrong definition of ULONG_PTR.
