MDAC installation check

[John Smith]

How can I check if MDAC is installed on the machine in Visual C++ ?

[Lost User]

There's a registry key HKEY_CLASSES_ROOT\MDACVer.Version with a subkey CurVer with the value like MDACVer.Version.2.60. I don't know if all MDAC version supports this key. Volker

use this code on ::InitInstance

CLSID clsid;
HRESULT hr = AfxGetClassIDFromString("Datalinks", &clsid);
if(!SUCCEEDED(hr))
{
    AfxMessageBox("You need to install MDAC v2.1 or higher");
    return FALSE;
}

:cool:
