I found a C++ function on the Internet which supposedly retrieves the ODBC driver name which matches "Excel" in the case below. I want to use the same function, but to be called inside a C# program instead of a C++ program. Does anyone know how to translate the function below to be run in C#? CString CReadExcelDlg::GetExcelDriver() { char szBuf[2001]; WORD cbBufMax = 2000; WORD cbBufOut; char *pszBuf = szBuf; CString sDriver; // Get the names of the installed drivers ("odbcinst.h" has to be included ) if(!SQLGetInstalledDrivers(szBuf,cbBufMax,& cbBufOut)) return ""; // Search for the driver... do { if( strstr( pszBuf, "Excel" ) != 0 ) { // Found ! sDriver = CString( pszBuf ); break; } pszBuf = strchr( pszBuf, '\0' ) + 1; } while( pszBuf[1] != '\0' ); return sDriver; }
