Overview
The InsertLine function will insert a line of text into a Mapped Text Object.
Syntax/Parameters
Syntax
int = InsertLine ( handle hMappedText, int index, string text );
Parameters
hMappedText
A handle to a valid Mapped Text Object.
index
An int containing the zero-based index of the line before which the data will be inserted. If the value is -1, the text is appended to the end of the object. A value of 0 inserts the text at the start of the object.
text
A string containing up to 1,048,575 characters to insert. The string must not contain control characters, such as return (“\r”) or new line (“\n”).
Return Value
Returns an int as ERROR_NONE or a formatted error code on failure. Use the GetLastError function to retrieve error information.
Remarks
The InsertLine function is a low-level function and therefore should not be used in conjunction with more complex editing features, such as when the Mapped Text Object is used with the transaction process. This function should also not be used with Mapped Text Objects retrieved from edit windows where using transactions is essential in enabling editing abilities such as undo. In these cases, use segment functions to adjust the text within the Mapped Text Object, such as the ReadSegment or WriteSegment functions.
If the hMappedText parameter is invalid, the GetLastError function will return ERROR_INVALID_HANDLE.
