Problem using LPD3DXEFFECT
Author
I have a class that handles post processing effects in my program. I can access and initialize all of the variables in the class including the LPD3DXEFFECT. However, if I load the effect using D3DXCreateEffectFromFile the program will crash as it is exiting. It is very strange because everything works fine until I exit the program. The error even comes up when I don't release COMs.
Here is the error I get:
The first thought that springs to mind is a memory leak somewhere but the DX Debug process should tell you that when you exit.
I don't recall seeing that problem with my old Effect Class. And just tested it with DXDebug switched on. It might be more basic than your own but here's what I have in it. Feel free to take a gander in case you spot something you overlooked.
Good luck. Hope you find the culprit soon.

Hope you find the culprit soon.

Now that I took it out of the class I do get a direct-x debug error. In fact I get about 2000 pages of:
[lol]
I took the effect and device out of a class and tried to see if it were the class protection that was the problem. It wasn't. So now I'm fairly sure the problem is the way I am loading it. Again, the program works perfectly until it exits. This is the code, maybe an error could be spotted:
Thanks!

//Select technique and store result
if(FAILED(g_pEffect->FindNextValidTechnique(NULL,&hTech)))
return FALSE;
if(FAILED(effectt=g_pEffect->ValidateTechnique(hTech)))
return FALSE;
if(FAILED(effectt=g_pEffect->SetTechnique(hTech)))
return FALSE;
I've never used these commands myself so will have to try it to see what happens in my case.
.. Okay, I added ValidateTechnique to my code and worked a treat. My effect file has multiple techniques in that have to be used specifically so can't use the FindNext option.
Also, what is effectt? it seems to be a variable of some manner but I am not seeing it being initialised, set or used anywhere else in that code. Ah I am guessing it is HRESULT variable.
Another thought I have is maybe try removing the use of the effect file and see if the program falls over using the fixed program functionality. I usually do this if I get a memory error and can't find where the owner of the problem is.

Yeah, I found part of the problem. I had to change m_dwShaderFlags to D3DXSHADER_DEBUG | D3DXSHADER_SKIPOPTIMIZATION.
Now it works fine using the release version of the directx sdk. However, I still get an error in debug mode =/. And I think it still wont work in its own class.
