[C++] Win XP vs. Win7 - debugs

[Czepek]

Hello. I've got problem related to the debug on Win7. I check which one code does debug - it is mana bar code. I've got Hawkye's code. I use 8.54 addresses, they are 100% correct, because it works on XP without any debug.

void GetActualGraphicEngine()
{
	int actualGraphicEngine =  *(int*)Address::GRAPHIC_ENGINE_MODE_ADDR;
	switch(actualGraphicEngine)
	{
		case 0:
			DrawRectAddress = Address::DRAW_RECT_DX5_FUNC_ADDR;
			break;

		case 1:
			DrawRectAddress = Address::DRAW_RECT_OGL_FUNC_ADDR;
			break;

		case 2:
			DrawRectAddress = Address::DRAW_RECT_DX9_FUNC_ADDR;
			break;
	}
}

DWORD PrepareDrawRectAddress = Address::PREPARE_DRAW_RECT_FUNC_ADDR;

void DrawRectangle(int nSurface, int X, int Y, int W, int H, int nRed, int nGreen, int nBlue)
{
	asm("mov %0, %%eax": /*no output opperand*/ : "r" (PrepareDrawRectAddress)); //We call the function that will prepare the registers for the DrawRect function
	asm("call *%eax");
	asm("mov %%eax, %%ecx": /*no output opperand*/ : /*no input operand*/ : "%ecx" /*we tell the compiler not to touch ecx anymore!*/);

	asm("push %0": /*no output opperand*/ : "g" (nBlue)); //We push all the parameters
	asm("push %0": /*no output opperand*/ : "g" (nGreen));
	asm("push %0": /*no output opperand*/ : "g" (nRed));
	asm("push %0": /*no output opperand*/ : "g" (H));
	asm("push %0": /*no output opperand*/ : "g" (W));
	asm("push %0": /*no output opperand*/ : "g" (Y));
	asm("push %0": /*no output opperand*/ : "g" (X));
	asm("push %0": /*no output opperand*/ : "g" (nSurface));

	asm("mov %0, %%eax": /*no output opperand*/ : "r" (DrawRectAddress)); //We call the DrawRect function
	asm("call *%eax");
}

void DrawRect(int nSurface, int X, int Y, int W, int H, int nRed, int nGreen, int nBlue) //Thanks to DarkStar and Farsa for the DrawRect Function
{
	GetActualGraphicEngine();
	DrawRectangle(nSurface, X, Y, W, H, nRed, nGreen, nBlue);
}

void __stdcall DrawBlackBarPatched(int nSurface, int X, int Y, int W, int H, int nRed, int nGreen, int nBlue)
{
	asm("movl %SS:-130(%ebp),%ecx");

	DWORD creaturePointer = *(DWORD*)Address::CURRENT_HP_BAR_DRAWING_CREATURE;
	DWORD creatureID = *(DWORD*)(creaturePointer);

	if(SendDlgItemMessage(mainWindow, IDC_MANABAR, BM_GETCHECK, 0, 0) == BST_CHECKED)
	{
		if(player.getID() == creatureID)
			DrawRect(nSurface, X, Y-6, W, H, nRed, nGreen, nBlue);
	}
	DrawRect(nSurface, X, Y, W, H, nRed, nGreen, nBlue);
}

void __stdcall DrawColorBarPatched(int nSurface, int X, int Y, int W, int H, int nRed, int nGreen, int nBlue)
{
	asm("movl %SS:-0x19C(%ebp),%ecx");

	DWORD creaturePointer = *(DWORD*)Address::CURRENT_HP_BAR_DRAWING_CREATURE;
	DWORD creatureID = *(DWORD*)creaturePointer;

	DrawRect(nSurface, X, Y, W, H, nRed, nGreen, nBlue);
	if(SendDlgItemMessage(mainWindow, IDC_MANABAR, BM_GETCHECK, 0, 0) == BST_CHECKED)
	{
		if(player.getID() == creatureID)
		{
			DrawRect(nSurface, X, Y, W, H, 0, 0, 0);

			DrawRect(nSurface, X, Y-6, W, H, nRed, nGreen, nBlue);

			DWORD width = (25 * player.getMP()) / player.getMPMax();
			DWORD percent = (100 * player.getMP()) / player.getMPMax();

			if(percent >= 80)
				DrawRect(nSurface, X, Y, width, H, 39, 64, 139);
			else if(percent >= 60 && percent < 80)
				DrawRect(nSurface, X, Y, width, H, 58, 95, 205);
			else if(percent >= 40 && percent < 60)
				DrawRect(nSurface, X, Y, width, H, 72, 118, 255);
			else if(percent < 40)
				DrawRect(nSurface, X, Y, width, H, 100, 149, 237);
		}
	}
}

I don't know well ASM to find what's going on.

The value returned from PrepareDrawRectAddress is the actual graphics engine. There's no need to determine it yourself.
