Hugo Marque #1 / 5	Problem wih resize after using CloneMesh Hi. I have a problem when trying to make a resize if i have use previously the CloseMesh function. The Vb6 crash completely and gives a General Protection Error. I've located where is the problem, and it's when calling to the method g_dev.reset. According with the documentation it's because i haven't freed all the memory i've taken. I'm sure i free all the memory before and in normal operation it works perfectely, but there is one moment in my application when I have to use the CloneMesh function to make a copy of a mesh. After using this function, if i try to call to the g_dev.Reset it returns me a D3DERR_DEVICENOTRESET error and after it, the application crash. If any of you have any idea why this is happening and how to solve it, please, send it to me. Thanks in advance Hugo Marquez

Could you show us how you are calling the CloneMesh function, maybe we can spot something. Other than that, I'm just not sure. -- Eric DeBrosse http://www.blown.com/dx/ Microsoft Visual Basic DirectX MVP The opinions expressed in this message are my own personal views and do not reflect the official views of Microsoft Corporation.

Hugo Marque #3 / 5	Problem wih resize after using CloneMesh Now I'm using the following code line to call the CloneMeshFVF: Set tempMesh = frame.GetChildMesh(0).Mesh.CloneMeshFVF(0, frame.GetChildMesh(0).Mesh.GetFVF, g_dev) Where tempMesh is a D3DXMesh, frame a CD3DFrame and g_dev a Direct3DDevice8 I've also tried using this other line, but I also get the problem with it. Set tempMesh = frame.GetChildMesh(0).mesh.CloneMesh(0, d3dxd, g_dev) Where d3dxd is a D3DXDECLARATOR Quote: >-----Original Message----- >> I have a problem when trying to make a resize if i have >> use previously the CloseMesh <spelling?> function. >> The Vb6 crash completely and gives a General Protection >> Error.

Instead of passing 0 in for the flags? Perhaps you could try D3DXMESH_MANAGED. This should survive a reset. -- Eric DeBrosse http://www.blown.com/dx/ Microsoft Visual Basic DirectX MVP The opinions expressed in this message are my own personal views and do not reflect the official views of Microsoft Corporation.

Hugo Marque #5 / 5	Problem wih resize after using CloneMesh You are right. Efectively that was the problem. Now I can make the reset without any problem. Thanks a lot for your help.
