    A logical suggestion, and likely the best. Thank you.

      Advanced Allocation/Deallocation in Memory

      Hi there,

      I'm coming to you nice people as a desperate resort with time working against me, anyway:

      I have implemented an algorithm that basically generates a very large tree of nodes, where each node just contains 4 pointers to other nodes.

      Now this generation of a tree occurs many times in the programs operation, and with the creation of new Node objects I gradually run out of memory. Obviously I need...

        in Java
        Oh dear, makes sense.

        Time is short so I've resorted to my backup plan and so my modelled adversary will just cipher his own message and overwrite the original cipher; I presume that no matter what I did, the resulting effect on the program would have been failure to decrypt, resulting in error of sorts.

        I suspect it will be enough of a proof.

        Thanks for your time and the time of all those that read my...

          Editing a cipher

          Hello,

          My scenario is as follows:

          I have a program that generates ciphertext, message-hash, key pair, (RSA) and I need to model a simple attack.

          Everything is fine, but one of the attacks I am having trouble with: I need to somehow 'modify' the byte array containing the ciphertext and prove that the receiver of the message propper will be able to detect the interference.

          Whats the best...

            Solved: Character Reading problem with ReadFile()

            I've figured it out. It was quite obvious really; use chars instead of DWORDS. Thanks for anyone who looked anyway.


            Hi,

            I've been having trouble with this for the past 48 hours. I hope someone can point me in the right direction. Basically I have a text file of characters. I want to read this into the program, but it's a Windows program so I'm using the open file dialogue.

            Everything goes fine;...

              Aha! Thanks, that worked and thus I am now pointed back on the root of the problem!

              Again, I thank you.

                Status Bar text display problem?

                Hi, I'll try and keep this quick and painless.

                I've created a status bar in my Win32 C++ code, and it works fine. Then I try assigning text the correct way:

                Code:
                LPSTR textString  = "Ready";
SendMessage((HWND) hwndStatus,(UINT) SB_SETTEXT, (INT) 0, (LPARAM)textString);
                It compiles fine, and everything is happy, only, instead of displaying the string 'Ready' it displays 2 squares (like character...

                  Sample Windows Applications - Special Request

                  Hi,

                  Im going to get straight to the point and explain my situation. I'm going to be programming a simple windows program in the C++ language with the MS Windows SDK in the not too distant future. I'm currently thinking about the user interface.

                  Now I can create quite easily a window, with the standard top toolbar (file, edit, help etc) but what I essentially want to do next is create a 'panel' down the right hand side...
