Project Type: InstallScript MSI
I'm trying to get a custom dialog box to get a property for one of my components (the name of a sql server). I'm using a custom property in the Property Manager but I can't set it from my InstallScript.
The MSIGetProperty and MSISetProperty always return ERROR_INVALID_HANDLE! To get the handle i'm using:
GetWindowHandle(HWND_INSTALL) and this returns a positive number.
Here are my calls:
installhandle = GetWindowHandle(HWND_INSTALL);
getresult=MsiGetProperty(installhandle, "SQLSERVER", svSQLServer, nBuffer);
setresult = MsiSetProperty(installhandle,"SQLSERVER",svSQLServer);
How can I get this to work?

What is the value of nBuffer? Try setting it to 256:
CODE |
function dostuff( hMSI ) NUMBER nBuffer; STRING szProperty; begin // MsiGetProperty buffer size nBuffer = 256; MsiGetProperty ( hMSI, "INSTALLDIR", szProperty, nBuffer ); end; |
If this doesn't work I would assume the handle you get is invalid.

Yes, I didn't know what handle to use. That was basically my question, but I found the answer by looking at some examples... The good handle is ISMSI_HANDLE.
Now it works.
Now it works.
