Was ist das Problem bei dem Textur-Laden?

[Eglifisch1]

Hi

Ich bin daran eine DLL zu Programmieren. Doch nun, wenn ich eine Textur laden will, wird sie nicht richtig geladen, hier ist ein Codeausschnitt:

// Cube3DEngineRenderer.h
//

#ifndef RENDERER_HPP
#define RENDERER_HPP

#include <windows.h>
#include "Cube3DEngine.h"

	float x, y, z;
	DWORD Color;
};

#define Cube3DEngine_FVF (D3DFVF_XYZ | D3DFVF_DIFFUSE)

namespace C3E

	class CUBE3DENGINE_DLL_API Cube3DEngineRenderer
	{
	public:

		Cube3DEngineRenderer();

		void SetRotationXYZ(float RadiusX, float RadiusY, float RadiusZ, float Radius);
		void SetObjectColor(float R, float G, float B, float A, float Power);

		bool SetTexture(LPSTR filename); // Das ist die Funktion, um eine Textur zu laden.

		bool LoadModel(char * filename);
		bool InitD3D(HWND hwnd);
		bool InitVertexBuffer(int VertexPoints);
		void InitTriangle(float x1, float y1, float z1, DWORD Color1, float x2, float y2, float z2, DWORD Color2, float x3, float y3,  float z3, DWORD Color3);

		void RenderObject(Cube3DEngineRenderObject RenderObject);
		void RenderModel();

	};
}

#endif

bool Cube3DEngineRenderer::SetTexture(LPSTR filename)
	{
		HRESULT hResult;

		if(FAILED(hResult = D3DXCreateTextureFromFileEx(g_pD3D->d3ddev,

		}

		return true;
	}

C3E::Cube3DEngineRenderObjects * Cube4;
Cube4 = new C3E::Cube3DEngineRenderObjects();
Cube4->InitCubeWithTexture("Wiese.jpg");

Kann mir jemand dabei helfen?

Ist die Textur auch vorhanden sprich ist dein Pfad zur Textur richtig? Ansonsten gibt dir der zurück gegebene Fehlercode genauere Hinweise darauf, was in deinem Code falsch gelaufen ist.

Ich habe zu begin den falschen Code geschickt, es wäre dieser hier:

		void InitCubeWithTexture(char * filename);
		void InitTriangle(float x1, float y1, float z1, DWORD Color1, float x2, float y2, float z2, DWORD Color2, float x3, float y3, float z3, DWORD Color3);

		void RenderCube();
		void RenderCubeWithTexture();
		void RenderObject();
		void RenderTriangle();

		void ClearCube();
		void ClearTriangle();
		void ClearVertexBuffer();

	private:

	};
}

	}

    // create a vertex buffer interface called v_buffer

    VOID* pVoid;    // a void pointer

    // lock v_buffer and load the vertices into it
    v_buffer->Lock(0, 0, (void**)&pVoid, 0);
    memcpy(pVoid, vertices, sizeof(vertices));
    v_buffer->Unlock();

    // create the indices using an int array
    short indices[] =
    {
        0, 1, 2,    // side 1
        2, 1, 3,
        4, 5, 6,    // side 2
        6, 5, 7,
        8, 9, 10,    // side 3
        10, 9, 11,
        12, 13, 14,    // side 4
        14, 13, 15,
        16, 17, 18,    // side 5
        18, 17, 19,
        20, 21, 22,    // side 6
        22, 21, 23,
    };

    // create an index buffer interface called i_buffer
    g_pD3D->d3ddev->CreateIndexBuffer(36*sizeof(short),
                              0,
                              D3DFMT_INDEX16,
                              D3DPOOL_MANAGED,
                              &i_buffer,

    i_buffer->Lock(0, 0, (void**)&pVoid, 0);
    memcpy(pVoid, indices, sizeof(indices));
    i_buffer->Unlock();
	}

C3E::Cube3DEngineRenderObjects * Cube4;
Cube4 = new C3E::Cube3DEngineRenderObjects();
Cube4->InitCubeWithTexture("Wiese.jpg");

Wenn ich nun das Programm starte, dann kommt diese Meldung:

MessageBox(NULL, "Fehler beim erstellen der Cube-Texture!", "Fehler aufgetreten",
					   MB_OK | MB_ICONEXCLAMATION);
