GetTableCellRingValueLengthFromIndex

int GetTableCellRingValueLengthFromIndex (int panelHandle, int controlID, Point cell, int index, int *length);

Purpose

Returns the value length, in bytes, of a specified item of the list of values of a specified ring or combo-box cell of a table control.

Supported Controls

You can use GetTableCellRingValueLengthFromIndex with table controls.

Parameters

Input
Name Type Description
panelHandle int Specifier for a particular panel that is currently in memory. You can obtain this handle from functions such as LoadPanel and NewPanel.
controlID int The defined constant, located in the .uir header file, that you assigned to the control in the User Interface Editor, or the ID returned by functions such as NewCtrl and DuplicateCtrl.
cell Point A Point structure specifying the cell from which you want to obtain the value length.

The specified cell must be of type VAL_CELL_RING or VAL_CELL_COMBO_BOX.

The Point structure is defined as follows:

typedef struct
   {
   int x;
   int y;
   } Point;


Pass the one-based column index of the cell in the x field of the structure, and the one-based row index of the cell in the y field of the structure.

You can create a Point without having to declare a variable by using the following function:

Point MakePoint (int x, int y);

Example

GetTableCellRingValueLengthFromIndex (panelHandle, controlID, MakePoint (2, 3), 0, &length);

index int The zero-based index into the list of values.

Output
Name Type Description
length int The number of bytes in the value of the specified item. The length does not include the terminating NUL byte.

Return Value

Name Type Description
status int Return value indicating whether the function was successful. A negative number indicates that an error occurred.
