Re: PVS 6.0 Michael P Butler8-Jul-02 0:43 Michael P Butler 8-Jul-02 0:43  I use VS6 on both 2000 and XP, and there are no problems. Just make sure you've got VS service pack 5 and are up-to date with the 2000 service packs.

That DLL is calling the TWAIN API and TWAIN is supposed to post messages to the caller to inform it on the current process. Unfortunately I'm using a MFC regular DLL with just the CWinApp class and I've no Windows Handle (hWnd) for posting TWAIN messages. I could post messages to the DLL caller and then back to the DLL but as this is a Plugin framework I don't want to use that method. At the moment I've created a fake Window in that DLL and I'm posting the messages to that Window but I'm wondering if there's a better way to do this.

PlaySound or sndPlaySound don't work Re: How to play a .wav file? 7-Jul-02 22:42 7-Jul-02 22:42  i am not sure but, u can try with "mciSendString" with Open Command and in Sharable mode Re: How to play a .wav file? 7-Jul-02 22:55 7-Jul-02 22:55  Hi guy, Please see the note: Note: from MSDN shareable::Initializes the device or file as shareable. Subsequent attempts to open the device or file fail unless you specify "shareable" in both the original and subsequent open commands. MCI returns an invalid device error if the device is already open and not shareable. The MCISEQ sequencer and MCIWAVE devices do not support shared files.

MrBean7-Jul-02 22:07 MrBean 7-Jul-02 22:07  I'm writing a automation EXE server in VC++ 6.0 and I want to send COM/ActiveX events to the calling program... is it possible and how ? The project was created as a MFC application with Automation support and works fine as a Automation server for my client application. Now I just need to notify the client of events in my automation EXE application. I'm desperately in need of help.... please help.... thanks Re: ActiveX events from automation server (.EXE) ? Fredrik Skog8-Jul-02 0:12 Fredrik Skog 8-Jul-02 0:12  Add a sink interface to your client that sink the events fired from the server. I think there are some samples in MSDN called koala or ekoala.

Re: ActiveX events from automation server (.EXE) ? Fredrik Skog8-Jul-02 2:01 Fredrik Skog 8-Jul-02 2:01  If you didn't like the koala samples, check here, there's plenty of articles about events.

MrBean8-Jul-02 21:07 MrBean 8-Jul-02 21:07  Well... there are plenty of samples but I still can't find any which shows how to add events to my EXE automation server (MFC). My automation server is a windowed application created as an MFC EXE application in VC++ and I want to send events back to the client when the user performs specfic actions in the window.

Dov Sherman7-Jul-02 21:29 Dov Sherman 7-Jul-02 21:29  I'm working on an application which contains a class called CSpecialWnd which is a child of CWnd. CSpecialWnd handles its own paint and timer events but I want it to be totally transparent to all mouse events. For example, if an instance of CSpecialWnd is running and it happens to be in front of a Notepad window, I should be able to click on CSpecialWnd but have Notepad still receive that click and not have CSpecialWnd get the focus.

I've have to build a autorun CD-Rom to automatically install my App from the CD. The installation is quite simple : I would like to copy files and folders, register the OCXs and DLLs, run a few batch files to setup some parameters, and that's all ! I started to have a look at InstallShield to do that, but it looks awfully complicated to me !!! Is it the good tool for what I want to do ? Is it possible to register DLLs, to run batch files with it and to easily copy files and folders ? Or should I just use another tool ? Thank you for your advices.... Jerome Re: InstallShield 56789012347-Jul-02 22:05 5678901234 7-Jul-02 22:05  InstallShield is possibly the best tool for building installations. When I opened it first time, I found Step By Step Help topic and built the simplest installation project quickly. You can find other features simply learning InstallShield IDE. For example, to register Dll you need to set "Self-Register" feature in File Groups. The power of InstallShield is that you have standard features in IDE and can write advanced actions using script. See also WEB site http://www.installsite.org which is like CodeGuru and CodeProject for InstallShield programmers, and it has also discussion groups. Re: InstallShield sagmam8-Jul-02 5:55 sagmam 8-Jul-02 5:55  First of all, InstallShield is THE-industry leading company for Setup applications. Its latest Developer 7 is what you need. It can build MSI-only (MS Windows Installer technology), InstallScript-only or an MSI-InstallScript project. Naturally, the latter is the strongest of them all, but I always prefer MSI-only. It's more simple, and if I need any extra code, I scribble a few VBScript lines, which are internally supported by the Windows Installer component. I have a lot of experience working with it. It's a monster, and many of the weird cases are a bit buggy. Luckily, you have the external utility ORCA, that helps you edit your project outside the IDE, and fix those bugs. It comes with Developer 7 on the CD. The documentation that comes with the IDE is not sufficient. You will also have to use MSDN for the MSI documentation (and VBScript if you're going to add you're own code... and you will!). Other good resources are the discussion boards at InstallSite.org and InstallShield.com. Good luck! /=/=/=/= Deus /=/=/=/=
