I've created a wrapper custom action dll with MsiGetProperty().From what i
see from MSDN,MsiGetProperty uses "MyProperty" as shown below;which is used
by the custom action. Can anyone help me understand this part? Where should
i get value for "MyProperty"?
<Snip> from MSDN site on MsiGetProperty:
UINT __stdcall MyCustomAction(MSIHANDLE hInstall)
{
TCHAR* szValueBuf = NULL;
DWORD cchValueBuf = 0;
UINT uiStat = MsiGetProperty(hInstall, TEXT("MyProperty"), TEXT(""),
&cchValueBuf);
if (ERROR_MORE_DATA == uiStat)
{
++cchValueBuf; // on output does not include terminating null, so
add 1
szValueBuf = new TCHAR[cchValueBuf];
if (szValueBuf)
{
uiStat = MsiGetProperty(hInstall, TEXT("MyProperty"),
szValueBuf, &cchValueBuf);
}
}
if (ERROR_SUCCESS != uiStat)
{
if (szValueBuf != NULL)
delete [] szValueBuf;
return ERROR_INSTALL_FAILURE;
}
// custom action uses MyProperty
// ...
delete [] szValueBuf;
return ERROR_SUCCESS;
}
Thanks
