未处理的异常directX [英] Unhandled exception directX

问题描述

我收到此错误



DirectXProgram.exe中0x012c17d2处的未处理异常：0xC0000005：访问冲突读取位置0x00000000。



这是我的代码..

I get this error

Unhandled exception at 0x012c17d2 in DirectXProgram.exe: 0xC0000005: Access violation reading location 0x00000000.

This is my code..

bool InitScene()
{
	//The vertices for the triangle
	Vertex vertices[] =
    {
        D3DXVECTOR3( 0.0f, 0.5f, 0.5f ),
        D3DXVECTOR3( 0.5f, -0.5f, 0.5f ),
        D3DXVECTOR3( -0.5f, -0.5f, 0.5f ),
    }; 

	//Filling the buffer descriptor 
	D3D10_BUFFER_DESC bd;
    bd.Usage = D3D10_USAGE_DEFAULT;
    bd.ByteWidth = sizeof( Vertex ) * 3;
    bd.BindFlags = D3D10_BIND_VERTEX_BUFFER;
    bd.CPUAccessFlags = 0;
    bd.MiscFlags = 0;

	//Sub resource data for the Input Assembler
	D3D10_SUBRESOURCE_DATA InitData;
    InitData.pSysMem = vertices;

	 d3dDevice->CreateBuffer( &bd, &InitData, &VertexBuffer );

	unsigned int stride = sizeof( Vertex );
	unsigned int offset = 0;
	d3dDevice->IASetVertexBuffers( 0, 1, &VertexBuffer, &stride, &offset );

	 D3DX10CreateEffectFromFile( "vertex.fx", NULL, NULL, "fx_4_0", D3D10_SHADER_ENABLE_STRICTNESS, 0,
                                         d3dDevice, NULL, NULL, &FX, NULL, NULL );

    Technique = FX->GetTechniqueByName( "Tech" );

	D3D10_PASS_DESC PassDesc;
    Technique->GetPassByIndex( 0 )->GetDesc( &PassDesc );

	d3dDevice->CreateInputLayout( layout, 1, PassDesc.pIAInputSignature,
                                          PassDesc.IAInputSignatureSize, &VertexLayout );

	d3dDevice->IASetInputLayout( VertexLayout ); 
	d3dDevice->IASetPrimitiveTopology( D3D10_PRIMITIVE_TOPOLOGY_TRIANGLELIST );
	return true;
}

休息时间 Technique = FX-> GetTechniqueByName（Tech ）;

推荐答案

根据您提供的信息，您不太可能得到过于具体的答案，但如果您的意思是它在FX上崩溃 - > Get ... by有一个中断...，然后很可能你的D3DX10CreateEffectFromFile（...）调用失败，检查 HRESULT [ ^ ]它返回以查看可能出错的地方。

With the info you provided it's unlikely you will get a too specific answer, but if you mean it crashes on FX->Get... by "There is a break at...", then most likely your D3DX10CreateEffectFromFile(...) call fails, examine the HRESULT[^] it returns to see what might be wrong.
