I saw in internet that I can use

SQLGetInstalledDriversW ( LPWSTR lpszBuf,
WORD cbBufMax,
WORD * pcbBufOut
)

but I don't understand how use this function

Richard MacCutchan 18-Jan-22 12:04pm

It is clearly documented at SQLGetInstalledDrivers Function - ODBC API Reference | Microsoft Docs[^].

Member 14594285 18-Jan-22 12:06pm

yes But I don't know how I must inizialized lpszBuf, cbBufMax and pcbBufOut

Richard MacCutchan 18-Jan-22 12:16pm

As I already stated, the documentation explains the use of each parameter.
lpszBuf must be a pointer to a buffer that will get the returned names.
cbBufMax is the length of this buffer.
pcbBufOut is the address of a WORD variable that is set by the API to the number of bytes returned.

Member 14594285 20-Jan-22 3:11am

TCHAR szBuf[2001];
WORD cbBufMax = 2000;
WORD cbBufOut;
TCHAR *pszBuf = szBuf;

/*LPSTR lpszBuf,
WORD cbBufMax,
WORD * pcbBufOut);

if (SQLGetInstalledDrivers(szBuf, cbBufMax, &cbBufOut))
{
int i = 1;
}

but I have this error: Severity Code Description Project File Line Column Suppression State
Error LNK2019 unresolved external symbol _SQLGetInstalledDriversW@12 referenced in function "protected: virtual int __thiscall CCReadLogDlg::OnInitDialog(void)" (?OnInitDialog@CCReadLogDlg@@MAEHXZ) CReadLog C:\Dev2015\Prg\CReadLog\CReadLogDlg.obj 1 1

You need to link the ODBC library to the application. Unfortunately the documentation fails to give its name.

Member 14594285 20-Jan-22 4:05am

Or is there an other way to see version of my "MySql Unicode Driver ODBC"?
Can I search for in my pc with path?

Richard MacCutchan 20-Jan-22 4:23am

Sorry, I have no idea. The documentation provided by Microsoft appears incomplete.

Member 14594285 20-Jan-22 4:32am

ok thanks

That's not a driver name. That's the filename of the installer to install a MySql driver.
