The Read procedure reads one line from the specified file.
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.
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 that holds the received line.
Remarks
The procedure below reads all characters up to the end-of-line marker, or up to the end of the file (see EOF). It does not skip to the next line, and every subsequent call to Read returns an empty string. If you want to read a set of string values, use ReadLn.
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 data from the file into the MyVar variable
Read(FileVar, MyVar);
// Outputs the data to the test log
Log.Message(MyVar);
// Closes the file
CloseFile(FileVar);
end;
