The ReadLn procedure reads one line from the file and moves the file pointer to the next line.
Declaration
| FileVar | [in] | Required | Variant | |
| Var | [in] | Required | String | |
| Result | None |
Description
Reads one line from the file, which is associated with the file variable by calling the AssignFile procedure, then assigns this line to the specified variable and goes to the next line.
Parameters
The procedure has the following parameters:
FileVar
Specifies the file variable, which is associated with the desired file by calling the AssignFile procedure.
Var
Specifies the variable, which holds the received line.
Remarks
If the ReadLn procedure does not have the Var parameter, it moves the file pointer to the beginning of the next line; if the current line is final, the pointer is placed at the end of the file.
Example
Since TestComplete works with variant variables, the received string can be converted to any other data type. The following example demonstrates how you can work with data received from the file.
DelphiScript
var
FileVar: OleVariant;
MyVar: OleVariant;
begin
// Opens a file
AssignFile(FileVar, 'C:\My File.txt');
Reset(FileVar);
// Reads a line into the MyVar variable
ReadLn(FileVar, MyVar);
// Outputs the data to the test log
Log.Message(MyVar);
// Closes the file
CloseFile(FileVar);
end;
