EditGetUTF Function

Overview

The EditGetUTF retrieves the data from an edit or static text control either in direct and in validation modes as UTF encoding.

Syntax/Parameters

Syntax

string = EditGetUTF ( int id, [string name], [int flags], [int size] );

Parameters

id

An int containing the control ID of an edit or static control.

name

An optional string specifying the name of the control. When specified, the function switches to validate mode and will test the content of the retrieved string according to the flags.

flags

An optional int specifying validation parameters for the type of field. If omitted, the value is set to zero.

size

An optional int specifying the maximum size of the field in characters.

Return Value

Returns a string containing the text or an empty string on failure or if the control does not contain any text. Use the GetLastError function to retrieve error information. In validation mode, the last error code will contain the control ID which can be returned directly to the dialog validate procedure to set focus on the offending control.

Remarks 

Though the EditGetText function is intended for use with edit controls, it will actually work on most control classes. Because an empty string does not necessarily indicate an error, the GetLastError function should be used to determine if the function failed.

If validation is enabled and validation fails, a standard message box will be displayed describing the error with the name of the field. The caller can pass the error code back from the validation procedure to set focus on the control containing the error.

The validation flags are as follows (bitwise combinations):

	Definition			Bits		Description

		EGT_FLAG_REQUIRED		0x80000000		Field Is Required

		EGT_FLAG_FILE_CAN_OPEN_READ		0x00000002		Check File can Open as Read (tests for exists as well)

		EGT_FLAG_FILE_QUERY_OVERWRITE		0x00000008		Query Overwrite

 

For edit controls, the maximum size of the text field will be limited by the physical size of the control unless the ES_AUTOHSCROLL style is set.

Proper security precautions should be employed when storing and using sensitive information such as passwords. This function abides by the Secure Memory Model.
