Telling the control not to sort isn't going to make any difference if the data you're adding is already sorted.

Beyond that, I doubt anyone will be able to help you based on the information provided.

You should use the Improve question button to add that to the question.
Try putting the items in a different order and see what happens.

The code you have shown suggests that you are adding the same string each time, which makes no sense. Please show the actual data and the code you are using.

Why are you doing the same reference twice, when you have already added it to the ComboBox? And what exactly is in the structure theApp.m_arrL?

Use Debug.Print for
theApp.m_arrL[nInd].m_strName
to see how the array values are sorted

The flag you are looking for is CBS_SORT. This sets the combobox up to automatically sort the strings. You can find bout more here[^].

To add to to this, you should also set the CBS_SORT style to be off for the combo box control. You can do this in your resource editor or programmatically using the 'CComboBox::ModifyStyle' method.

You need to use the 'CComboBox::InsertString' method instead of 'CComboBox::AddString' method, see - MS Learn | CComboBox Class [^]

Your code should be -

C++

for (INT_PTR nInd = 0; nInd < nNum; nInd++) {
    int index = combo_lin.InsertString(nInd, theApp.m_arrL[nInd].m_strName);
    if (index == CB_ERR) {
        // Handle error
    }
    str = theApp.m_arrL[nInd].m_strName;
}
