c++mfcccombobox

C++ MFC CComboBox is empty

i've a little comboBox, and i want to fill it with 6 entries... . i wrote this code:

CComboBox* dropdownList = ((CComboBox*)GetDlgItem(IDC_PROGRAMDROPDOWN));
dropdownList->Clear();
dropdownList->AddString(L"test");
dropdownList->AddString(L"test2");
dropdownList->InsertString(2,L"test3");
dropdownList->InsertString(3,L"test4");
dropdownList->InsertString(4,L"test5");

As you can see I tried AddString(), and InsertString(). both with no effect. I also tried it just with AddString() which should be the correct way at initializing it.

But, my combobox is empty. I already debugged it, and this lines are hit but with no effect.

Do you have any idea?

Solution

  • thanks for all your answers. But it was an ugly Failure by my IDE -.-. I just recreated the UI-Element and it worked...

    I recreated it with the same properties (Copy & Paste)
