Uses a specific control in the active window to acquire the index of the item text.

bool AIT_CtrlItemIndex  (
  string strCaption,     // Control's caption
  integer nCtrlType,     // Control type
  string strItemText,    // Item text
  integer nIndex         // Item index
  [,float fTimeOut]      // Time-out
);
bool AIT_CtrlItemIndex  (
  integer nCtrlID,       // Control ID
  integer nCtrlType,     // Control type
  string strItemText,    // Item text
  integer nIndex         // Item index
  [,float fTimeOut]      // Time-out
);

strCaption (input)

Specify the caption of a control.

nCtrlID (input)

Specify a control ID.

nCtrlType (input)

Specify a control type, which must be one of the following values.

Value	Description
COMBO_CTRL	The control type is a combo box.
LISTBOX_CTRL	The control type is a list box.
TREE_CTRL	The control type is a tree control.
LIST_CTRL	The control type is a list control.

strItemText (input)

Specify an item text for acquiring an index.

nIndex (output)

Specify a variable for receiving the text index. When the function returns, the variable stores the index for the item text. The default index value is 0.

fTimeOut (input, optional)

Specify the maximum time the function can use to find the control, in units of seconds. The default is the value set in the AIT_SetDefaultWaitTimeout function.

The return value is true if the function was executed normally, and false if not.

If the function has returned false, you can use AIT_GetLastError to acquire an extended error code. The following gives the error codes that AIT_GetLastError may return.

Extended error number	Error code
6	ERROR_INVALID_HANDLE
8	ERROR_NOT_ENOUGH_MEMORY
14	ERROR_OUTOFMEMORY
87	ERROR_INVALID_PARAMETER
112	ERROR_DISK_FULL
1400	ERROR_INVALID_WINDOW_HANDLE
1413	ERROR_INVALID_INDEX
1460	ERROR_TIMEOUT

You can identify the control by using a complete caption or an associated label name or specifying the first part of such a caption or label name. When specifying the first part, prefix a swung dash (~) to the character string that you specify.
