• Visual Basic Using the progressbar

  This is what I am trying to do: Copy a file from my resources to the temp directory. Get the size of the file in my resources in bytes. For every byte that is copied I want to step the progressbar by 1. The part I am having troubles with is getting the size of my file. I want to get the size so I can set the progressbar's maximum property to the same value. Also, would it be a good idea to use a background worker for this Thanks. Then simply total up the size of the files. Getting the file size in bytes using fileinfo. When each file copies then update your byte count and compare to the total byte count, calculate a percentage ...Show All

• Visual C# File Upload with restricted extensions not working

  I have a file upload class, and in it's constructor it needs to be able to take in an array of possible file extensions (using the new params keyword) I won't know how many or what extensions are being passed in, but once they are only those passed in are allowed to be uploaded. The class I'm having problems with inherits from it's parent class that works fine and doesn't restrict anything. The new inherited class compiles fine, but still allows anything to uploaded, even when I've specified ".doc" as the only type allowed.

• Visual Studio Express Editions Build doesn't work

  Every time I build a project and get a .exe file I can't send it to anyone. Why I have one file Kekke.exe in the debug folder which I can open but when I tried to send it to my other computer it couldn't open it.. What happens 1. I asume that you build a native exe that uses the CRT in a DLL. So you need the DLLs of the CRT. http://www.codeproject.com/useritems/vcredists_x86.asp 2. You are not allowed to redistribute the DLLs of the Debug build, so only copy the Release Builds! ...Show All

• Visual C# How do I test a button when running an event?

  I have a start button which runs a section of code continuously - how do I test the stop button while this code is running Colin, it is usually not a good idea to have an event executing for a long time, as while you are serving an event, the other events get blocked. This amounts to freeze the user interface. If you plan to have a lengthy task running in response to a button click, you should probably use a Thread, or the ThreadPool. It's fairly easy to use, and it's well worth the little time it takes to set them up, as the code becomes cleaner and easier to manage. Anyway, there is another option, ...Show All
