Hey

i need to multiply 2 LONGs to a LONGLONG (64-bit width integer), without it overflowing.

I've heard the Mul64 function does this, but what header(s) do i need to include for this.
Please respond quickly!! Blush | :O

Int32x32To64 will do the job. Or you can use __int64 builtin type if you're using VC6.

Thanx, but I really need the exact Mul64 function since I'm using code provided by a company and don't want to change it unneccesarily.

What c++ header file contains Mul64??

Cheers

There's no such animal, according to MSDN. You need to ask the source you "heard" it from.

Hi all,

I don't know if it's legal to distribute Microsoft fonts with my application. I especially need the "Tahoma" font.

Is it possible to distribute the font together with the software package as a .ttf file, or perhaps Microsoft has some executable which installs this font, or is it just completely illegal Confused | :confused:

?

Thanks in advance.

Last I heard, it is *not* legal to re-distribute Microsoft fonts.

You can download Microsoft's redistributable TrueType fonts from here. Tahoma isn't one of them.

My ATL/DLL dont works in Delphi program althouth I provided the files:
.dll and .tlb as you say me past.

I found in Delphi web that probably have to perfom some translation to the header file

I asked from my Delphi client to do that translation and I sent him to that address: www.drbob42.com/delphi/headconv.htm that explains it .

He tried that translation of the header file but he claims that now his compiler claims that there are missing files as below:
oaidl.h
ole2.h
rpc.h
rpcndr.h
windows.h

All this files exists in the vc/include folder

What can do ????? Confused | :confused:

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

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

C DLL Wraper

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 | :)

Jon Sagara23-Oct-01 22:41

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

Jon Sagara

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,

How do I Get The App Path?

23-Oct-01 21:45

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.

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!
