#include "ltwrappr.h"

static L_INT LVectorDialog::GetStringLen(uString, puLen)

L_UINT32 uString;	/* index of a string */
L_UINT * puLen;	/* pointer to the variable to be updated */

Gets the length of the string at the specified index.

Parameter	Description
uString	Index into a list of strings. For a list of the strings, refer to Dialog Strings.
puLen	Pointer to an unsigned integer variable to be updated with the length of the item's current character string.

Returns

SUCCESS	The function was successful.

Comments

Once you know the length of the string at the specified index, retrieve the text by calling LVectorDialog::GetString.

Use LVectorDialog::SetString to modify the text.

Before calling this function, you must declare an unsigned integer variable. Then, pass the address of the variable in the puLen parameter. This function will update the variable with the length of the automation item's character string.
