Create the button with set check Icon in the Propeties of Button.

Then use SetIcon() method for put the Icon to the button!

COULD SOMEONE HELP ME OUT AS TO HOW TO WRITE A WRAPPER IN Visual C++ 6

I have a dll (SbLm_LogClient.dll ) written in C which I need to use in my vb code. The DLL functions uses _cdecl convention hence I an getting errors. I guess the way round it is to write a wrapper in C++ using the __stdcall convention. I know the dll exposes two interfaces.
Interface 1 - SbLm_Log accepts an Integer and a Char
Interface 2 - SbLm_CloseLogClient is a sub, it accepts no parameters

I have an include (.h) and a .a file from the from the author. The content of the .h file is below

#ifdef WINDOWS_NT
#ifndef SbLm_LogClient_h_included
#define SbLm_LogClient_h_included

#ifdef BUILDING_DLL
#define DLLIMPORT __declspec (dllexport)
#else /* Not BUILDING_DLL */
#define DLLIMPORT __declspec (dllimport)
#endif /* Not BUILDING_DLL */

DLLIMPORT int SbLm_Log(int, char *);
DLLIMPORT int SbLm_CloseLogClient();

#endif // SbLm_LogClient_h_included
#else
int SbLm_Log(int, char *);
int SbLm_CloseLogClient();
#endif

Question:
1) What will the code in the .cpp file be to call this two interfaces from a new COM dll

Hi Guys,

I am retrieving a field from an Access database and then comparing it to something the user enters looking for a match.

However I don't get a match if the case is different. (of course)

How do I do a compare that doesnt care about the case???
or how do I change a CString var to all lower case

Any help greatly appreciated.
Thanks Guys,

Tryhard Smile | :)

CString::MakeLower() to make it lower case.

I can't think of anything original to say.

CString::CompareNoCase() might help.

CString::CollateNoCase - uses current code page for comparisons.

Look up CString class members. There is one just for this purpose.

P.S. Learn to use MSDN. Its ALL in there.

Hope this helps,

This might be a dumb question, but I have spent weeks trying to figure it out, so here goes. When I first start my MFC app, is there a way to get the applications path? That is, the path to where the application's exe file is? I need this information, so I can access the help file, text files, etc which are in the app path. I have tried MSDN, the web, 'hacking' existing functions, etc, but so far have had no success.

Use __argv[0] to get the complete filename of the .exe - __argv is the global variable. Then, perform a reverse search for '\' using CString::ReverseFind to cut the exe name from path.

How to limit a zone of scrolling of the View?

24-Oct-01 0:09

This code I find on the PJ Naughter's site (http://www.naughter.com/)

CString CSpltestApp::GetHomeDirectory() const
{
  TCHAR sFilename[_MAX_PATH];
  TCHAR sDrive[_MAX_DRIVE];
  TCHAR sDir[_MAX_DIR];
  TCHAR sFname[_MAX_FNAME];
  TCHAR sExt[_MAX_EXT];
  GetModuleFileName(AfxGetInstanceHandle(), sFilename, _MAX_PATH);
  _tsplitpath(sFilename, sDrive, sDir, sFname, sExt);

  CString rVal(CString(sDrive) + CString(sDir));
  int nLen = rVal.GetLength();
  if (rVal.GetAt(nLen-1) != _T('\\'))
    rVal += _T("\\");

  return rVal;
}

I frequently use it, work perfectly!

Best regards,

I have the class based from CScrollView! How to make so that scrolling it was carried out not in all window, but only in any part!
For example, I want to place not scrolled heading to the top of View! OMG | :OMG:

Capture WM_SCROLL and then don't pass the message on if the values fall outside the area you want.

The device context you're receiving in CYourView::OnDraw is prepared to draw using coordinates altered by current scrolling position. If you want top part of your view to remain top regardless of the scrolling, you have two options:

1) draw the top part not at the (0, 0) coords, but at the position returned by GetScrollPosition - this should be the top-left corner of visible area (I'm assuming that you're running in MM_TEXT mode).

2) use other device context for top part of the view in OnDraw - just declare a CClientDC. Draw at (0, 0).
