using a 3rd party activex control

[Conrad Hoffman]

This COM stuff isn't as easy as falling off a log, is it? I want to use an ActiveX control provided by the people I work for. It has about 70 functions for controlling a small motor via a USB port. The simplest function just throws an About Box up on the screen, so I thought I'd start there. My objects seem to create ok, but no about box displays. I just modded the MSAgent demo code. Any thoughts on what more I need to do?

To use a visual AxtiveX control you need an OLE container. What you have to do depends of the container. Here is an example of how to embed the Windows Media Player ActiveX control using ATL.DLL as the container: http://www.jose.it-berater.org/smffo...p?topic=2714.0

[Conrad Hoffman]

Thanks- I'll try that tonight!

[Conrad Hoffman]

Hi Jose- the amount of work you've done with this stuff just boggles the mind! I see about what's going on, but can't compile the examples. I assume the two include files are created with the PBrowser (does the version of Media Player matter?), and what file do the equates like %true come from? That's where my compile fails.

[José Roca]

To compile the examples without modification you need to use my new include files instead of the ones provided by PB. You can download them at http://www.jose.it-berater.org/smffo...sg8191#msg8191

I also have my own browser: http://www.jose.it-berater.org/index.html

[Conrad Hoffman]

That fixed up the compile, but still no joy with my control. Oddly, the program does succeed in bringingup my dial-up window! This control drops into VB and C++ programs at work- a C++ and VB-centric place, but it would be really nice if I could get it to work through PB. Here's what I tried-

I've no doubt my problems are due to my complete lack of understanding of this stuff, but maybe it will also help if I post the PBrowser include file I'm using:

CONTROL ADD "AtlAxWin", hDlg, %ID_NST, "NstSquiggleCtrl.ocx", 0, 0, 0, 0, %WS_VISIBLE OR %WS_CHILD

You must not use the name of the OCX, but the ProgID.

Use:

CONTROL ADD "AtlAxWin", hDlg, %ID_NST, "NSTSQUIGGLECTRL.NstSquiggleCtrlCtrl.1", 0, 0, 0, 0, %WS_VISIBLE OR %WS_CHILD

[José Roca]

I guess that you have been confused because the example uses "WMPlayer.OCX", but it happens that this is the ProgID of the Windows Media Player control, whose file name is WMP.DLL.

[Conrad Hoffman]

Hurrah! Thank-you, that does it, and yes, I thought it was the file name. I do have to use OBJECT CALL or I get method-or-property-expected error. The first step is hardest, but now that I can get one response from the thing, the rest should come a lot easier. Thanks again.

Conrad

[José Roca]

You have to use OBJECT CALL/GET because it has a dispatch-only interface, not a dual one. Therefore, direct interface calls can't be used with it.
