I need to find a way for my the second instance of my program to communicate with the first instance. I've already got the files associated and the program will open and load the file when I click on the file.

I need the second instance to tell the first instance to load the next file when clicked. I'm using hmutex to do this. I have tried using hmutex and SendMessage to do this but keep getting access denied from SendMessage.

As a last resort I tried to use hmutex and DestroyWindow to shut down the first instance and load the second one and get access denied from DestroyWindow. After that I researched that I couldn't do this.

I just need to find a way to find a way load the next file clicked instead of having a popup stating that my application is already loaded.

Any suggestion?

Thanks, Roger

Hi Roger,

I wrote and tested this, so hopefully it does what you want.

Thanks, I'll try this shortly when I get time to get into it. This looks similar to what I tried to do before but I didn't use WmLiberty.

I do use WmLiberty for drag and drop. So I got the drag and drop working from when I pm'ed you a few days ago.

Just so you know, I'm using this in my Mp3 player, ChallengerAmp.

You can get it from rtsystemcomponents.com/Camp/Camp.html .

I'll delete the above line if you want.

I'll try this later when I get time.

Thank, Roger

Thanks for the help. This headed me in the right direction. With some modifications and additions I have implemented it into my application. I just need to debug some more but it seems to be working good now.

The reason I kept getting access denied error before is I was trying to use the securityAttributes struct.

Thanks, Roger
