Here are the codes:


Test.cpp

[source lang="cpp"]


#include "Sprites.h"

LPCTSTR Test_BMP::getFileName()
{
LPCTSTR file = "C:\\test.bmp";
Test_BMP::FileName = file;
return file;
}

bool Test_BMP::getAttributes()
{
HRESULT hResult = D3DXGetImageInfoFromFile(Test_BMP::getFileName(), &(Test_BMP::Image_Info));
if (hResult != D3D_OK)
{
DWORD error = GetLastError();
char errorString[32];
sprintf_s(errorString, "Error: %x", error);
MessageBox(NULL, TEXT(errorString), TEXT(__FUNCTION__), MB_OK);
return false;
}
if (Test_BMP::FileName != NULL)
{
hResult = D3DXLoadSurfaceFromFile(Test_BMP::Surface, NULL, NULL, Test_BMP::FileName, NULL, D3DX_DEFAULT, 0, NULL);
if (hResult != D3D_OK) //D3DERR_INVALIDCALL Problem!!
{
char errorString[32];
sprintf_s(errorString, "Error: Line %d", __LINE__ - 4);
MessageBox(NULL, TEXT(errorString), TEXT(__FUNCTION__), MB_OK);
return false;
}
}
else
return false;
return true;
}

And this is "Sprite.h"

[source lang="cpp"]

#include "Core.h"
#include "main.h"

class Sprite
{
public:
LPCTSTR FileName;
RECT SourceRect;
RECT DestinationRect;
LPDIRECT3DSURFACE9 Surface;
D3DCOLOR TransparentColor;
D3DXIMAGE_INFO Image_Info;
//-----------------------------------------------------
Sprite();
~Sprite();
bool Blit();
bool SetRects(RECT Source, RECT Destination);
virtual LPCTSTR getFileName();
virtual bool getAttributes() = 0;
};

class Test_BMP : public Sprite
{
public:
LPCTSTR getFileName();
bool getAttributes();
};

[/source]


What it will do when the program run, it will pop-up a message box saying that on Line 23, it returned D3DERR_INVALIDCALL error. There are some functions I didn't use from Sprite.h. I have given the D3DXLoadSurfaceFromFile() the most minimal valid parameters, yet it still failed. That, my friend, is a nutty problem.

Due to that, I've decided to upload all of my project's source code, so as to let everyone see what's the problem. Thanks in advance to those who are helping out, as I'm beat from debugging this for over [size="4"]56 hours straight... since 5/12/2011.


[size="5"]EDIT: I have uploaded my project folder, along with a README.txt inside. That way, everyone can see it obviously.

Through the process of debugging when you stepped through each param are they valid? i.e. Surface = LPDIRECT3DSURFACE9 & FileName = LPCTSTR?
I know you probably debugged this six ways to Sunday... just trying to wrap my head around why an inherited member would be causing you an issue...strange indeed.

Yes. All returned valid. It has all correct content in each of the parameters.

Also, for some reason, the first post does not contain my project files. I'd better put them here. My project requires a BMP picture in the C: hard drive, or a valid file path for any BMP files. The BMP image is included in the project ZIP file.

EDIT 2: Forum file upload is broken. ZIP files become headerless ZIP files. Please add the extension name ".ZIP" at the end.


EDIT 3: ZIP file is now located at the very top and at very bottom.

You're all set...you are going to kick yourself when you see what I changed I've attached a screenshot to show I got it running.

Cheers...

Um. I couldn't see what changes have you added (it's not obvious ). Is it okay if you can tell me? Can you blit out the "test.bmp" via inheritence?

I did check the source code you've uploaded, and then I looked at your screenshot. You might have mistaken the problem with with the error at hand.

The correct results should be a "test.bmp" being blit to the screen, while at the same time, it is able to inherit the Sprite class.

Huh? All I did was replace the source codes in my project with yours, did check to see if it contains your change, which it did, then rebuild, compile, run it, and I get this. As far as I can tell, that error you get in your screenshot, it meant to say that the "test.bmp" is missing. I should revise my error messages so that it's more understandable. I apologize about that.

Did you have the "test.bmp" in the C:\ directory? (The file location should be in full name: "[color="#00bfff"]C:\test.bmp") I've already placed the picture in the ZIP file in my earlier post, and just wanting to check to see if you have that picture there.

Bump. Please help while you can. I can guarantee you, I can confuse you with my code.

Here's the project folder, in case you have actually missed the first post. Instructions inside!
