Sample

This sample reads a file named MyFile.txt and displays its content in the oTextEdit1 control.

Procedure ReadFile
    String sFileName

    Move "MyFile.txt" to sFileName

    Send Read of oTextEdit1 sFileName
End_Procedure

Sample

This sample allows the user to select a file using an OpenDialog control, and then displays the content of the document the user has selected in the oTextEdit1 control. This sample assumes that an OpenDialog control named oOpenDialog1 exists in your code.

Procedure ReadFile
    String sFileName
    Boolean bOk

    Set Filter_String of oOpenDialog1 to 'Text Files (*.txt)|*.txt|All Files (*.*)|*.*'
    Get Show_Dialog of oOpenDialog1 to bOk
    If (bOk = True) begin
        Get File_Name of oOpenDialog1 to sFileName
        Send Read of oTextEdit1 sFileName
    End
End_Procedure
