Mark Churchill Director Dunn & Churchill Re: Reversible Cipher Question Luc Pattyn13-Sep-07 4:07 Luc Pattyn 13-Sep-07 4:07  Although not strictly letters, maybe a simple hex representation is sufficient, i.e. replace each encrypted byte by two characters in [0-9A-Z]. byte.ToString("X2") would do that for you. And byte.Parse(string, NumberFormat.HexNumber) would undo it.

Luc Pattyn13-Sep-07 4:12 Luc Pattyn 13-Sep-07 4:12  The "best" way for you may not be the best way for your customer. I for one will not buy a license that is fixed to a specific piece of hardware, since as soon as my hardware needs a replacement, my software needs a new license resulting in unnecessary hassle and cost. I like the concept of dongles, i.e. a small USB device that holds the key for the licensed app or apps (Google for "software protection", Wibu, Safenet, and others). As a customer I can now move may app+key to whatever machine a like, but I can run it only on the machine that has the dongle.

Pete O'Hanlon13-Sep-07 3:10 Pete O'Hanlon 13-Sep-07 3:10  There are some very expensive applications which will "bake" the .Net runtime into your executable so they will run without .Net being installed. However, it is fairly trivial to include the .Net redistributable as a dependency in an installer so that it will be installed if it is not present.

You can access individual characters like this: mystring[i].

Thanks!: Designing forms and using them in just one window? xelontr13-Sep-07 1:36 xelontr 13-Sep-07 1:36  Hi, I have designed some programs on SWT and Swing using Java. There are many similar features that both c# and java have. When programming with Java I was using just one window(form) and than embed a necessary panel to it. Panels are designed seperately and named differently. For example one panel named SavePanel.java is used to save an entry(think about an address book). When the saving process is done, other panel named SearchPanel.java is called to the window. So when the user presses a button, a panel that is related to that process is called to the form. In C# I can't find any feature like this. When I create a panel, I cannot add buttons or textboxes to them. The visual editor cannot show them. I don't want to design one form for saving and one form for searching. Just one form is enough. According to the process that user wants some part of the form will be change. And changing part have to be designed easily using visual editor. If any of you made something like this before, or any idea similar to this problem, please help me. Any articles, documents or related websites will be helpful. Thanks Re: Designing forms and using them in just one window? Urs Enzler13-Sep-07 1:44 Urs Enzler 13-Sep-07 1:44  You have to add and remove UserControls to your main Form. A UserControl for Save and one for Search. Depending on what to do, add either of them to the Form. UserControls can be designed with the Designer (Editor). -^-^-^-^-^- no risk no funk ................... please vote ------> creation of a service Bojja Lakshmi13-Sep-07 1:34 Bojja Lakshmi 13-Sep-07 1:34  Hi Friends, I need to create a service(windows) in c#.
