Event Subscriber Crashes App.. need help :(

[Mystique7]

Hi all,

Just started on CEGUI, and am so far very impressed.. it looks like it should save me a lot of time!

Have a small problem though that has been bugging me for the past couple of hours. Have read as many related topics on this forum about it as I can, and have tried many solution but nothing has worked so far.

The problem is that my App crashes with an 'Illegal Operation' style error. When I run the debugger, it says 'Access violation reading location 0x00000008'. Now, I'm pretty sure this error stems from the Event Subscriber function.. here's my code:

Code: Select all

   WindowManager& winMgr = WindowManager::getSingleton();
   Window* window = winMgr.getWindow("testWindow/Controls/Add");
   window->subscribeEvent(PushButton::EventClicked, Event::Subscriber(&GUI::handleButton, this));

bool GUI::handleButton(const CEGUI::EventArgs& e) {

   // Do stuff here
   return true;
}



As can be seen, its all pretty normal looking (I think), however, if I comment the line beginning 'window->subscriber...' out, the App doesn't crash .

Other notes on my situation are as follows:

I'm using Visual C++ 6.0 'cos Visual Studio 2003 keeps screwing stuff up, however, I'm currently using the RELEASE CEGUIBase.dll for the VS2003 build. This is because all other builds (CEGUIBase_d.dll and CEGUIBase.dll from the VS6.0) give 'Procedure Entry Point could not be located in x.dll' errors, even when I compile my own .dll

Anyway, any help would be greatly appreciated.

Thanks.

The code looks fine, but the combo of visual studios sounds like trouble to me though!

Ah right.. I didn't know there would be that much difference in the .dll files. I'd use the VS6.0 .dll files, but as I've already mentioned, they cause an error within themselves If I can get that sorted, it might be a step in the right direction.

Thanks for your help.

Well, I think I've got it working now. I decided to switch to VS2003, and use the VS2003 DLL files. App doesn't crash now, which is good, but the event doesn't work either I think thats my fault though.

Hmm, just wondering though.. is there much difference between the DEBUG and RELEASE DLLs? I ask because the VS2003 DEBUG DLL gives an error about directx_27.dll or something, which is included in the August 2005 DirectX9.0 redistributable, but I can't install it 'cos *cough*haxedwindows*cough* I do now have a legit CD-Key, but I don't really want to format just yet.

There are links on google to a directx 9 sdk feb 2006 that do not require windows genuine validation!

Well I have the Feb SDK (had it for a while now), but it still whines about that .dll from August
