Thread: Problem with a 2D array.

Hi I'm dynamically creating a 2D array and I'm trying to write somethin to it but I get a run-time error that memory could not be read. I use the exact same code a few lines before it and it works fine, but this one fails. Here's the code:

Code:

           Vic **mtxVicValsB;
	mtxVicValsB = new  Vic*[vars.NumScan];

	for(i=0; i<vars.NumScan; i++)
		mtxVicValsB[i] = new Vic[VicSize3];

	mtxVicValsB[0][0].Name = "name";    <-- This line gives an access violation error

// and Vic is

          struct Vic
	{
		float Value;
		CString Name;
	};

Any ideas on what's going on and how to get rid of the propblem?

I'm not familiar with the CString class, but I assume that the proper operator= is defined.
Make sure your sizes for the array are positive.

And, what compiler/OS?

Cheers

I'm using MS 6.0. and I I passed it a wrong variable to allocate the size. That's why it was getting confused. It wrks llike a charm now.

thanks though.

Word of caution. MSVC 6 is a pre-standard compiler, and tends to do some things in "funny" ways. Might want to consider upgrading to a standards compliant compiler at some point: gcc (Dev-C++), or .NET, or something similar.

Glad you got it working.

Cheers
