Hi Everyone,

The first parameter of the MsiSetProperty function calls for a handle to the installer. Where or how can I get this in my install script code?

I'm using DevStudio 9, if it matters.

Thanks in advance.

Sincerely,

C++ or Installscript?

Installscript:
export prototype test (HWND);

function test ( oneMSIDB)
//
begin
MsiSetProperty ( oneMSIDB, "PROPERTY", "1");
end;

Hi Glytzhkof,

Thanks for getting back to me so quickly. I got the part you listed. I'm using Installscript, btw.

What I don't know is where you are initially getting the handle. So to use your example,

//test(HWND) defined in previous post

HWND myhandle;

myhandle = ?????;//what goes here?

test(myhandle);


It is what goes into the question mark that I don't understand. Do you know?

Thanks again,
Mike

Hi again,

I just found the function GetWindowHandle(flag). Is this the function the handle that I'm looking for?

//-------------------------------------------------------
//please see the previous posts
HWND myhandle;

myhandle = GetWindowHandle(HWND_INSTALL);

MsiSetProperty(myhandle, ...., ....);

//--------------------------------------------------------

Thanks again,
Mike

Ok, I think I found my answer. It looks like the handle I need is: ISMSI_HANDLE.

As far as I recall I include the base Installshield runtime and then this handle is implicit in a BasicMSI project:

#include "ifx.h"

possibly also"

#include "isrt.h"
