    Posted: 14 April 2008 at 7:26am
Hi,
 
I have created a listbox in the resource statically and set its OwnerDraw property as fixed and have checked the Has Strings property.
In the header file I have changed the CListBox variable into a CXTCheckListBox variable.
In OnInitDialog I have initialized the checklistbox member variable by calling on the API     m_RoutedTrailsList.Initialize();
Now, when i have to dynamically add some items into the checklistbox and check or uncheck them based on certain conditions. I run a for () loop within which i check or uncheck the item by calling
                m_UnroutedTrailsList.SetCheck(iCount, 1); or
                m_UnroutedTrailsList.SetCheck(iCount, 0);
where my iCount denotes the index of the items and it begins from 0.
But I do not get the behaviour as expected, the code executes as expected and calls on m_UnroutedTrailsList.SetCheck(iCount, 1); for 4 times, each time incrementing iCount as expected.
But it checks only 3 items, the first item remains unchecked.
Can anyone give me a solution to this problem? Has anyone faced a similar problem before?
An immediate response is eagerly awaited.
Thanks,
Devam.

I cannot oleg. The company has its Information Security policies which prohibit me from uploading code at a public forum.
Anyways, I think its some issue with the index that I am using for setcheck()
Is there any issue with setcheck() like in case of CTreeCtrl where the style has to be set at the runtime only? Here do I need to call on a ModifyStyle () or some other API?

Thanks for the help oleg. It worked!

I simply took the index which was returned after I called AddString(), and then used the same index to perform a SetCheck().

Lesson learnt: Never use a loop counter or any other variable as index while doing a SetCheck(). Always take the return value from the AddString API and then use the same return value to perform a SetCheck().
