ReadBytes Method

Applies to TestComplete 14.91, last modified on July 20, 2021

Description

Use the ReadBytes method to read data from a file and convert it to a sequence of bytes.

Declaration

aqBinaryFileObj.ReadBytes(Count)

aqBinaryFileObj An expression, variable or parameter that specifies a reference to an aqBinaryFile object
Count [in]    Required    Variant    
Result aqBytes object

Applies To

The method is applied to the following object:

Parameters

The method has the following parameter:

Count

Result Value

The aqBytes object that represents a sequence of obtained bytes. You can read and write individual bytes in it, as well as obtain the length of the sequence.

Remarks

To use this method, you need to open the needed file with the faRead or faReadWrite access permission. See the description of the OpenBinaryFile method.

Example

The code below demonstrates how you can use the ReadBytes method:

JavaScript, JScript

function Bytes()
{
  Path = "C:\\MyFiles\FileName.txt";
  
  // Reads the content of the specified file
  myFile = aqFile.OpenBinaryFile(Path, aqFile.faRead);
  
  // Reads bytes from the file
  s = myFile.ReadBytes();
  myFile.Close();
  
  // Writes the received array to the file
  myFile = aqFile.OpenBinaryFile(Path, aqFile.faWrite, true);
  result = myFile.WriteBytes(s);
  
  myFile.Close();
}

Python

def Bytes():
  Path = "C:\\MyFiles\FileName.txt"
  
  # Reads the content of the specified file
  myFile = aqFile.OpenBinaryFile(Path, aqFile.faRead)
  
  # Reads bytes from the file
  s = myFile.ReadBytes()
  myFile.Close()
  
  # Writes the received array to the file
  myFile = aqFile.OpenBinaryFile(Path, aqFile.faWrite, true)
  result = myFile.WriteBytes(s)
  
  myFile.Close()

VBScript

Sub Bytes
Dim Path, myFile, s, result

  Set Path = "C:\\MyFiles\FileName.txt"
  
  ' Reads the content of the specified file
  Set myFile = aqFile.OpenBinaryFile(Path, aqFile.faRead)
  
  Set s = myFile.ReadBytes()
  
  Call myFile.Close()
  
  ' Writes the received array to the file
  Set myFile = aqFile.OpenBinaryFile(Path, aqFile.faWrite, true)
  Set result = myFile.WriteBytes(s)
  
  Call myFile.Close()
End Sub

DelphiScript

procedure Bytes;
var Path, myFile, s, result;
begin
  Path := 'C:\\MyFiles\FileName.txt';
  
  // Reads the content of the specified file
  myFile := aqFile.OpenBinaryFile(Path, aqFile.faRead);
  
  // Reads bytes from the file
  s := myFile.ReadBytes();
  myFile.Close();
  
  // Writes the received array to the file
   myFile := aqFile.OpenBinaryFile(Path, aqFile.faWrite, true);
   result := myFile.WriteBytes(s);
   
   myFile.Close();
end;

C++Script, C#Script

function Bytes()
{
  Path = "C:\\MyFiles\FileName.txt";
  
  // Reads the content of the specified file
  myFile = aqFile["OpenBinaryFile"](Path, aqFile.faRead);
  
  // Reads bytes from the file
  s = myFile["ReadBytes"]();
  myFile["Close"]();
  
  // Writes the received array to the file
  myFile = aqFile["OpenBinaryFile"](Path, aqFile.faWrite, true);
  result = myFile["WriteBytes"](s);
  
  myFile["Close"]();
}
