C++, DirecX 9: Render Self-made Vertex Struct - c++

Question

I'm new on StackOverflow and this is my first question.
I'm very new to C++ and DirectX9 so their may be a lot of Issues in my Code!
My Question:
I would like to Render an Structure of "D3DXVECTOR3"s for making a Heightmap from a .raw.
I have a working FP Camera System and want to implement a Heightmap. I followed the Tutorial "Terrain in DirectX9 and C++" (https://www.tutorials.de/threads/tutorial-terrain-in-directx-9-und-c-teil-1.343473/), but the Code don't work properly (The Tutorial is in "Bad" German, I used It because I didn't found any Tutorial for a Heightmap in DirectX9. ...And I'm german).
All it output is This (Ignore the Cylinder, it's only a test):
renderissue
Here are some relevant Parts of the Code:
Heightmap.cpp
BOOL LoadMapFromRAW(char* pcHMAP, UINT sizePerSide, BYTE **ppData)
{
BYTE *pData = NULL;
FILE *pFile = NULL;
// Open as Binary
pFile = fopen(pcHMAP, "rb");
if (!pFile)
return false;
// Memory
pData = new BYTE[sizePerSide*sizePerSide];
// Read
fread(&pData, 1, sizePerSide*sizePerSide, pFile);
*ppData = pData;
return true;
}
BOOL CreateVertices(UINT sizePerSide, BYTE *pVertexData, STerrainVector **ppVertices, UINT *uiTriangleCount)
{
UINT uiSizePerSide = sizePerSide - 1;
*uiTriangleCount = uiSizePerSide*uiSizePerSide*2;
// Memory for Vertices
STerrainVector *pVertices = new STerrainVector[(*uiTriangleCount) * 3];
// Buffer
int index = 0;
for (int x = 0; x < uiSizePerSide; x++)
for (int z = 0; z < uiSizePerSide; z++)
{
index += 6;
pVertices[index + 0].vPos = D3DXVECTOR3(x, pVertexData[z * sizePerSide + x], z);
pVertices[index + 1].vPos = D3DXVECTOR3(x, pVertexData[(z + 1) * sizePerSide + x], z + 1);
pVertices[index + 2].vPos = D3DXVECTOR3(x + 1, pVertexData[z * sizePerSide + x + 1], z);
pVertices[index + 3].vPos = D3DXVECTOR3(x + 1, pVertexData[(z) * sizePerSide + x + 1], z);
pVertices[index + 4].vPos = D3DXVECTOR3(x, pVertexData[(z + 1) * sizePerSide + x], z + 1);
pVertices[index + 5].vPos = D3DXVECTOR3(x + 1, pVertexData[(z + 1) * sizePerSide + x + 1], z + 1);
}
// Done
*ppVertices = pVertices;
return true;
}

....Had a Hard time with the Code.....
The "*pHeightData; *pVertices; uiTriangleCount" are defined at the start of the Code.
I Hope you can help me!
I apologize for the the bad english: I'm German and still in School! :-)
Thanks in Advance!

Answer 1

So... I solved by myself. The solution was: Complete rewrite! For anyone with the same/similar problem: http://www.riemers.net/eng/Tutorials/DirectX/C++/Series1/tut13.php That is a very good Tutorial I've found! Try It!
