How can I initialize the combox if I start my project with default value

[Stephane Fonteyne]

Dear support,

I don't find the FF function for ComboBox for initialize the value with an highlight default when start the application

I see now when start the application all the four combobox are empty. I want to see that when I started the application default values highlight in the combobox

cboBaud  = 9600
cboParity = N
cboData  = 8
cboStop  = 1

I see this :

cboBaud  = " "
cboParity = " "
cboData  = " "
cboStop  = " "

Can someone help me in the right direction?

If you add your combobox strings using the "(Custom)" property in the "Properties" tab, then in order to set the default selected item you can change the value of the "InitialSelection" value also found on the "Properties" tab. By default, the "InitialSelection" property is -1 wheich means that nothing is selected.

To set the initial selection via code you would use the FF_ComboBox_SetCurSel function most likely in the WM_CREATE message handler.
