I am looking for a way to use the TRACE macros without adding MFC to my project. Does anyone have macro definitions to do this?

Thanks Chris, I just about got this far, but where is the OutputDebugString function declared?

I'm currently using <fstream> to dump my TRACE output to a file, but I would prefer it to come into the IDE so I can see it while it runs.

OutputDebugString is a Win32 API function. #include Windows.h to get it. (it's actually in winbase.h).

it's what TRACE ends up calling. ODS will even dump stuff in release mode, hence the #ifdef _DEBUG.

you can even use the lovely WinDBG32 app to capture these message outside of the IDE.

Thanks, I gave it a try and it worked. This is the first time I've actually had a question. It's great the speed with which this community answers questions.

You can just grab the code for AfxTrace() from the MFC\src directory and copy it to your program, too. There's also ATLTRACE if you are using ATL.

When I set a WH_MOUSE hook,how can I get the class of the control which was clicked by leftmouse?

If you have mouse coordinates, try with WindowFromPoint() and ChildWindowFromPoint(), then use GetClassName() to know which control it is.

Hope this helps,

NetApiFreeBuffer and W95/98/Me

Hi !

Before use any command from NetApi32.DLL ( NetAPIFreeBuffer and all that stuff), I check if the version is not 95/98, .... but anyway if I try to run the EXE in a machine with 95/98 it gives me an error ( I think when tries to load the DLL or... ? I´m not sure).

Is there anyway to avoid that ? ( If I can run the program in 98 the specific NT functions never will be executed, because of the checking...).

Thanks, Bye !

Problems with Visual Studio

Hi,

I've experienced the strangest behaviour of my VS 6.0. I have project with multiple, hierarchially dependent sub-projects (each one comprising a dll). I added some code to a header file of the most basic sub-project and compiled it. The compilation went fine, VS went into linking, I heard a beep and the compilation froze! I tried to shut down VS but was told that I had to stop the compilation first, but stopping it from the menu or the button didn't have any effect. I eventually had to cold-boot my Win95 system. I removed the coded I had added, and it went fine. I added it again and compilation went fine. I made some other (very small) changes, it crashed on compilation again!

Does this ring a bell for anybody? Any suggestions?

Cheers
Steen.

Are you running Norton AntiVirus on 9x/Me by chance? There's a known bug with NAV 2000/2001 (maybe 2002, I haven't tried it yet) that'll lock VC when it either runs the help compiler or regsvr32. Disable Auto-Protect to work around this.

Wow, thanks! Yes, I'm running NAV on Win95, with autoprotect on. I'll try to disable it and see if the problem goes away. BTW, VC doesn't really lock, it just never finishes the build (but the UI works fine).

Do you know if NAV causes any problems with Adaptec CD Creator as well? Creator won't recognize my CD writer (although Direct CD works fine!)

Hi,

disabling Auto-Protect certainly did the trick, thanks again. However, the compilation froze (with Auto-Protect on) either during the creation of the browse database or during invocation of a post-linking step (a file copy). So this bug is not just when running help compiler or regsvr32.

Cheers
Steen.

Yeah, the IDE will hang when launching any external program. Regsvr32 is just what most people get the hang with since that's used so often.
As for your CD writer, I don't know. Check Symantec's knowledge base and Adaptec's site.

Did that. Since the Adaptec sw came with the writer it's OEM and out of Adaptecs (actually it's Roxios) hands. I'll have to contact the writer producer (Samsung). But I'll upgrade my PC and install win98 instead one of these days, and I'll install NAV as the very last program. I'll check that everything works before NAV, and if anything breaks after NAV I'll fry their support.

thanks for your help

I'm not sure, but you may use ShellExecuteEx() with a special Verb.

I use the following statement to show the property of a file. But it does not work.

ShellExecute(AfxGetApp()->GetMainWnd()->m_hWnd,"properties","c:\\autoexec.bat",NULL,NULL,SW_SHOWDEFAULT);

How to resolve the trouble?

Try with ShellExecuteEx and SEE_MASK_INVOKEIDLIST .

info.lpFile="c:";

Can you help?

From PJ Naughter's CFileTreeCtrl class:

BOOL CTreeFileCtrl::ShowProperties(HTREEITEM hItem)
{
  BOOL bSuccess = FALSE;
  if (m_bAllowProperties && hItem)
  {
    //Show the "properties" for the selected file
    CString sFile = ItemToPath(hItem);
    SHELLEXECUTEINFO sei;
    ZeroMemory(&sei,sizeof(sei));
    sei.cbSize = sizeof(sei);
    sei.hwnd = AfxGetMainWnd()->GetSafeHwnd();
    sei.nShow = SW_SHOW;
    sei.lpFile = sFile.GetBuffer(sFile.GetLength());
    sei.lpVerb = _T("properties");
    sei.fMask  = SEE_MASK_INVOKEIDLIST;
    bSuccess = ShellExecuteEx(&sei);
    sFile.ReleaseBuffer();
  }
  return bSuccess;
}

So you can blame him if that doesn't work Wink | ;)

Just replace ItemToPath() with your filename.
