thank you guys.
yes, my problem was in varCount initialization.
and i have another problem. when i write
intVec.
the property container menu of intVec doesn't appears.

Intellisense doesn't work ? That doesn't really matter, does it ?

How?

Because, it can easily happen, that you skip that specific value, for whatever reason. You could accidently increase the counter twice, initialize it with a value larger than varCount and stuff like that. It's just a matter of clean and readable code. If you want a loop to run as long as i is less or equal some other value, then you should write your condition that way. Lots of problems and timewasting during debugging happen due to such dirty practices.
Then again, STL-Iterators work just that way ( it = YourVector.begin(); it != YourVector.end(); it++ ), but that don't mean it's good =).

Actually, I dont follow coding style, by OP,too. All points mentioned by you are valid.
But in given code , that doesn't matter.
As revealed later, it was initializatin problem.

Actually, he probably would have caught it sooner because I'm guessing it was something like this:
void CQMDlg::OnGetvarCountButton()
{
varCount = -1;
for(int i=0; i!=varCount; ++i)
{
intVec.push_back(i);
}
}
Which will run forever, whereas if the code was written as:
void CQMDlg::OnGetvarCountButton()
{
varCount = -1;
for(int i=0; i<varCount; ++i)
{
intVec.push_back(i);
}
}
It would have been caught immediately since the vector would have been empty.
As a side note, STL's iterators use != for a reason. For most of the containers, there is no guarantee that the memory locations are sequential, so you can't do a < comparison to find the end of the loop.

I have used this as well as the other one bellow not at same time definitely
char *names[3];
names[0] = "Joe";
names[1] = "Billy";
names[2] = "Bob";
for(int i=0;i<=2;i++)
m_ctrldestcombobox.AddString((LPCTSTR)names[i]);
*****************************************************************
m_ctrldestcombobox.InsertString(1, "SAP R/3");
m_ctrldestcombobox.InsertString(2, "PLM SERVER");
thanx pls reply even if i m acting foolishly

As seems, you are using VS2005. This code works fine with small modification
CString names[3];
names[0] = "Joe";
names[1] = "Billy";
names[2] = "Bob";
for(int i=0;i<=2;i++)
m_combo.AddString(names[i]);

I tested your code it was working,did you check return value of AddString what return value?

If you have entered string there, it should be semicolon(;) separated.

No semicolon is required.

In original post, he mentioned setting data using DATA field in properties window. There you have to insert data (;) separated.
Let's say I want to display three items added initialy viz. "tom","dick" and "harry", you can add it in DATA field with (;) as separator; as "tom;dick;harry"

No you don't. Each item goes on a separate line. No semicolon is required. This is in the context of VC++ v6.

What value are they returning?

Exactly how are you verifying this?

Is the combobox "tall" enough? The default height is way too small.
