Thread: Reset Combo Control VS C++ 6.0

I think I have a relatively simple question, yet I have not found a relatively simple solution.

I am loading a combo box control using using .AddString ():

Code:

//list files in combo box box for data files
m_DataFile.AddString(file.c_str());
UpdateData(false);

That works fine and I am pleased with my results. However, I want to be able to clear the values listed in the combo box based on the value of check box state. I successfully add values to the combo box if it is checked, but I want to clear the list in the combo box so it shows no values if the box is unchecked.

So far the code below clears most of the values but some still remain, so I know this logic is flawed. Any suggestions? Am I going about this the wrong way?

Code:

//clear the combo box of current values
		int count = 0;
		//clear the combo box setting it blank values
		do
		{
			m_DataFile.DeleteString(count);
			UpdateData (false);
			count ++;
			
		}while (count != numberPackages);

Any help is greatly appreciated. Thanks-
