Description
The ReadShort method retrieves two bytes from a binary file (starting from the current cursor position) and treats them as an integer value.
Declaration
aqBinaryFileObj.ReadShort()
| aqBinaryFileObj | An expression, variable or parameter that specifies a reference to an aqBinaryFile object | |||
| Result | Integer | |||
Applies To
The method is applied to the following object:
Result Value
The integer value read from the file.
Remarks
On success, the cursor position is shifted by 2 bytes.
Keep in mind that writing an integer value shifts the cursor position either by 4 or by 8 bytes, whereas reading an integer value can shift the position by 1-8 bytes depending on the method used.
Example
The code below demonstrates how to use the ReadShort method.
JavaScript, JScript
function ReadingDataFromBinaryFile()
{
Path = "C:\\MyFiles\\FileName.txt";
// Creates a new file and opens it for writing in binary mode
myFile = aqFile.OpenBinaryFile(Path, aqFile.faWrite, true);
// Writes data to the file
myFile.Write(152);
// Closes the file
myFile.Close();
// Opens the file for reading
myFile = aqFile.OpenBinaryFile(Path, aqFile.faRead);
// Reads data from the file
Log.Message(myFile.ReadShort());
// Closes the file
myFile.Close();
}
Python
def ReadingDataFromBinaryFile():
Path = "C:\\MyFiles\\FileName.txt"
# Creates a new file and opens it for writing in binary mode
myFile = aqFile.OpenBinaryFile(Path, aqFile.faWrite, True)
# Writes data to the file
myFile.Write(152)
# Closes the file
myFile.Close()
# Opens the file for reading
myFile = aqFile.OpenBinaryFile(Path, aqFile.faRead)
# Reads data from the file
Log.Message(myFile.ReadShort())
# Closes the file
myFile.Close()VBScript
Sub ReadingDataFromBinaryFile()
Dim Path, myFile
'Set Path = "C:\MyFiles\FileName.txt"
' Creates a new file and opens it for writing in binary mode
Set myFile = aqFile.OpenBinaryFile("C:\MyFiles\FileName.txt", aqFile.faWrite, true)
' Writes data to the file
Call myFile.Write(152)
' Closes the file
Call myFile.Close()
' Opens the file for reading
Set myFile = aqFile.OpenBinaryFile("C:\MyFiles\FileName.txt", aqFile.faRead)
' Reads data from the file
Call Log.Message(aqConvert.IntToStr(myFile.ReadShort))
' Closes the file
Call myFile.Close()
End Sub
DelphiScript
procedure ReadingDataFromBinaryFile;
var Path, myFile: OleObject;
begin
Path := 'C:\MyFiles\FileName.txt';
// Creates a new file and opens it for writing in binary mode
myFile := aqFile.OpenBinaryFile(Path, aqFile.faWrite, true);
// Writes data to the file
myFile.Write(152);
// Closes the file
myFile.Close();
// Opens the file for reading
myFile := aqFile.OpenBinaryFile(Path, aqFile.faRead);
// Reads data from the file
Log.Message(aqConvert.IntToStr(myFile.ReadShort()));
// Closes the file
myFile.Close();
end;
C++Script, C#Script
function ReadingDataFromBinaryFile()
{
Path = "C:\\MyFiles\\FileName.txt";
// Creates a new file and opens it for writing in binary mode
myFile = aqFile["OpenBinaryFile"](Path, aqFile.faWrite, true);
// Writes data to the file
myFile["Write"](152);
// Closes the file
myFile["Close"]();
// Opens the file for reading
myFile = aqFile["OpenBinaryFile"](Path, aqFile.faRead);
// Reads data from the file
Log["Message"]( "The bolean is: "+ myFile["ReadShort"]() );
// Closes the file
myFile["Close"]();
