Hi, I am a beginner ASM programmer and I was trying to learn more about the WINAPI reading through the examples. I have been going through the source code of Quetannon and there is a particular invocation that has puzzled me. It appeared twice in the code, in lines 146 and 203.


In the context of line 146, this invocation is being done just after setting the resolved IP address into the ipaddress control. But I don't get why this is needed at all. According to the documentation, the CB_ADDSTRING message adds a string to the list box of a combo box. But in our case we don't even have a combo box where the hostname will be added!
Similarly in line 203, we are making the same invocation just after retrieving the text from ID_COMMAND control

Again, I fail to see what it does here. Removal of both the lines doesn't affect the program at all either. What am I missing here?

Okay did I just post this in the wrong section? Maybe this should have been in the Windows section, I don't know.

Indeed, it is strange.
This dialog does not have even one combo box.
Maybe Tomasz knows - he is marked as an author of this code.

Moved to Windows forum.

Perhaps the combobox was removed at one point and those lines were forgotten about and left behind.

Yes, this program used to have comboboxes with history (like fasmw's search window, for example). Apparently I forgot to remove these lines when simplifying the dialog.

Well that makes sense! Thanks.
