Problems with using a Long as a loop index

Hi there, I've got the header of my model file loading fine, from what I can tell it's loading without any problems. The next step is to the load the actual model data. The problem I'm having is that the number of vertices is stored as a long like so: newObject->hVertices. Now the problem I'm having is when I try and use it in a for loop, it crashes out the program for (long t = 0; t < 12; t++) { tempBuffer = (float*) malloc (sizeof(float)); fread(tempBuffer,1,sizeof(float),model); fileData.oTVertices.push_back(*tempBuffer); } That works fine. However, if I do this for (long t = 0; t < newObject->hVertices; t++) { tempBuffer = (float*) malloc (sizeof(float)); fread(tempBuffer,1,sizeof(float),model); fileData.oTVertices.push_back(*tempBuffer); } That crashes out. Any suggestions? Cheers

You know, you post code thinking that people will read it and try to understand what it means. Not copy and paste verbatim.

I think your problem might be here -->

if((model=fopen(path,"r"))==NULL)

If this is Windows you should (from memory) be using 'rb' because you are binary encoding the value. This should be for both the read and the write. Windows c-style file stuff behaves differently to linux/unix on this.

<edit - snip>
learn to use cout or the debugger to make sure values are what you expect
