Description
Use the Cursor property to read the current position or to set a new position within a text file.
Declaration
aqTextFileObj.Cursor
| Read-Write Property | Integer |
| aqTextFileObj | An expression, variable or parameter that specifies a reference to an aqTextFile object | |||
Applies To
The property is applied to the following object:
Property Value
A zero-based integer that denotes a position in a file.
Remarks
After the file is opened, the Cursor property points to the end or to the beginning of the file. If the file is open for reading, Cursor points to the beginning of the file. If the file is open for writing or appending, Cursor points to the end of the file (the cursor is positioned right after the last byte of the file’s content).
Example
The code below reads the content of the specified file and posts it by letters to the test log.
JavaScript, JScript
function ReadFile()
{
var sPath = "D:\\Files\\MyFile.txt";
// Opens the specified file for reading
var myFile = aqFile.OpenTextFile(sPath, aqFile.faRead, aqFile.ctANSI);
// Reads the first line and posts it by letters to the test log
while (! myFile.IsEndOfFile() )
{
// Obtains the letter and its number
var sLet = myFile.ReadString(1);
var lNum = myFile.Cursor;
Log.Message("The " + lNum + " letter is:");
Log.Message(sLet);
}
// Closes the file
myFile.Close();
}
Python
def ReadFile():
sPath = "D:\\Files\\MyFile.txt"
# Opens the specified file for reading

# Reads the first line and posts it by letters to the test log
while not myFile.IsEndOfFile():
# Obtains the letter and its number
sLet = myFile.ReadString(1)
lNum = myFile.Cursor
Log.Message("The " + str(lNum) + " letter is:")

# Closes the file
myFile.Close()VBScript

' Obtains the letter and its number

lNum = myFile.Cursor
Log.Message("The " & lNum & " letter is:")
Log.Message(sLet)
WEnd
' Closes the file
myFile.Close
End Sub
DelphiScript

var sPath, myFile, sLet, lNum;

lNum := myFile.Cursor;
Log.Message('The ' + IntToStr(lNum) + ' letter is:');
Log.Message(sLet);
end;
// Closes the file
myFile.Close();
