Hey, i recently found out why my codes never work.
They fail on every directx function!
EG:


 IDirect3DSurface9* surface = NULL;
 D3DXIMAGE_INFO imageInfo;
 if(FAILED(D3DXGetImageInfoFromFile(fname,&imageInfo)) && 
 FAILED(DX::g_pd3dDevice->CreateOffscreenPlainSurface( imageInfo.Width,imageInfo.Height,imageInfo.Format,D3DPOOL_DEFAULT,&surface,NULL)) && 
 FAILED(D3DXLoadSurfaceFromFile(surface,NULL,NULL,fname,NULL,D3DX_DEFAULT,0,NULL)))
 return(false);
 return(true);

returns false.
How can i see the erro code?

The 'FAILED' macro simply checks the return value (of type HRESULT) from those functions against the value 'D3D_OK'.

So instead simply do:

HRESULT hr = whateverD3DFunction();

That'll give you the result from each function so you can check for specific errors as they are reported.

You can also turn on / increase the debug output via the DirectX control panel that comes with the SDK.

the first hresult converted to int is -2005529767.
Where do i find its meaning?

Check the documentation.

It will state what return values you will get when calling DirectX functions.

You don't say which call failed ?

That doesn't look like a proper error code :S

Anyway, this function translates DX errors.

LNK2019: undefined reference to external symbol _DXGetErrorDescriptionA@4
Which lib do i have to link? MSDN does not specify that

Ok, here is the code and the error


 D3DXIMAGE_INFO imageInfo;
 HRESULT hr = D3DXGetImageInfoFromFile(path,&imageInfo);
 const char* a = DXGetErrorDescription(hr);
 MessageBox(0,a,"asd",MB_OK);

error: Invalid Data.
damned directx..

edit: ok, it was because D3DXGetImageInfoFromFile doesen't accept .png files..
i'm trying with .bmp, and device->CreateOffscreenPlainSurace(..) gives me the error: Invalid Call.
Resolved, i was trying to use a non-supported surface format
