    I have found another solution. Writing here if someone needs this thing in future.

     

    //open as binary file

    var binFile = aqFile["OpenBinaryFile"](stringFilePathBinFile, aqFile["faReadWrite"]);

    // Reads bytes from the file
    readBytesFromBin = binFile["ReadBytes"]();

    // Obtains the number of items in the array returned by ReadBytes()
    countBytes = readBytesFromBin["Count"];
    for (var i = 0; i < countBytes; i++)
    {
    // Obtains the current item
    var byteValue = readBytesFromBin["Item"](i);

    //convert it to ascii code and store it in string
     var stringBinFile =stringBinFile+ aqConvert["VarToStr"](aqString["Format"]("%c", aqConvert["VarToInt"](byteValue)));
    }

Hi,

 

TestComplete does not provide hex file editor.

Can you post/attach here a sample file?

Hello AlexKaras 
It's a .dll file. Its not supported here.
Anyways, I used the function to open the file as Binary and editing file as byte data. Which is working for now. But I am not sure if it is good method or not.

    Hi,

     

    > I am not sure if it is good method or not.

    I think this is acceptable method because, as you correctly noted, binary file edit is not something that TestComplete is oriented at and thus it does not provide hex editor.

    From programming point of view your method is quite correct, as for me.
