- Organization of this page
Description
Checks the index of the first visible item in a list box.
Format
integer AIT_VerifyFirstVisible ( string strCaption, // Control's caption integer nCtrlType, // Control type integer nIndex // Index ); integer AIT_VerifyFirstVisible ( integer nCtrlID, // Control ID integer nCtrlType, // Control type integer nIndex // Index );
Parameters
strCaption (input)
Specify the caption of a control.
nCtrlID (input)
Specify a control ID.
nCtrlType (input)
Specify a control type for which only LISTBOX_CTRL is valid.
nIndex (input)
Specify a control's index. As the index is based on 0, the index for the first item in a control is 0.
Return values
The return value is 1 if the specified index matches the index for the first visible item, 0 if not, and -1 if the function has not been processed successfully. If -1 has been returned, you can use AIT_GetLastError to acquire an extended error code. The following gives the error codes that AIT_GetLastError might return:
