How to set selected text in Combobox

[tnjgraham]

Hey,
I am working on this project where I need to retrieve the system com port settings and update a dialog in my project to reflect the system settings. However all of the system setting aren't supported by my projec. For example, baud rate of 300 isn't supported by my project, but I will like it to be appear as a selected value for the combo box. I have tried SetWindowText() to do this but this only work if the combobox is a drop down type combo box which I can't have because this type allows the user to edit the box. My combo box is a drop list type, which doesn't allow edit.With this in mind, is there anyway I can change the text of a combo box that is a drop list type. Any help will be greatly appreciated.

Thanks In Advance
