get selected item in combobox

[FibiIA]

hi all,

i need to get the selected item from a combobox, there are functions i see. But no one seems answer the need.

best regards

Did you check the combodemo project? There you read the (selected) text value from the string control and compare it with your predefined text strings.

hi

where can i find this project, there is not in the help of labwindows

The simplest is using the NI Example Finder, search for combo and it will list two projects.

You can find it also in the help (with some luck), search for combo, choose combo box function tree, choose one function and scroll to the end of the page where it will list two examples.

On my system, it is in Documents and Settings/All Users/Documents/National Instruments/CVI2010/samples/userint/custctrl/

This code is supposed works to get the selected item but ther is an error which is in the function IsListItemChecked: attribute passed invalid. What is the error 

for (int i=0;i<maxitems;i++) {
IsListItemChecked (PANEL, PANEL_RING, 1,&checked);
if (checked)
{
GetValueFromIndex (PANEL, PANEL_RING, i, value);
GetLabelFromIndex (PANEL, PANEL_RING, i, label);
}
}

...because the combo box is not a ring control but based on a string control

in fact it's a listitem but it is the same as a combobox.
