• Windows Forms MDI Application -> freezing certain windows?

  Hi, Im creating a program that allows a user to run sql commands etc. I want commands to be executed concurrently in different windows. So when someone executes a command in one window, I would like a box to pop up saying "time running etc etc cancel etc"... but while this box is open I dont want the user to be able to hide it and view the window it was ran from, but still be able to view other windows within the MDI application to see results from other sql commands etc. How would I go about this....is there an inbuilt method to freeze a window, or would I have to do it manually (ie when a user clicks on the window when a box is open, check ...Show All

• Visual C# How I can connect a form to several db in C#?

  Hi, I want to know if there is a way to switch from a form to more than one database. Is possibile use, for example, two database toghether Thank you!  I have moved your thread to the C# General forum so you get better responses. You can easily connect your C# application to multiple databases by creating various different connection objects that connect to different databases. If you are using the VS IDE you can drag and drop different Connection objects from the toolbox and configure each one to connect to a seperate database.

• Visual C# Unable to load class library

  I wrote a managed wrapper in C++/CLI and compiled it under AMD64. Now I wrote a client in C++/CLI too and this works well. Trying to do the same in C# I got everything to compile but when I run it it says: Unhandled Exception: System.IO.FileNotFoundException: The specified module could not be found. (Exception from HRESULT: 0x8007007E) at MyClass.Main() This is weird though. I compiled the C# file for 'anycpu' but trying to set the platform to x64 did not do any difference. The class library is even located in the same directory.  It was compiled using the RC:         csc /out:test_cs.exe tes ...Show All

• Visual Studio Need to move VSS database with WEB project.

  Hi We use VSS version 6.0c, on the windows 2000 with IIS5, I have a couple of VSS databases. Now I want to migrate databases to another server. In my case this is the file storage without IIS.

• Visual Studio Express Editions Decompile Prevention.

  Do you know if any ways to prevent my executables from being decompiled My 5 year old does this. She asks me a question, then says 'how do you know' There is a tool that will compile your .NET app to machine code ( not MSIL ) and therefore is as safe as C++ code. Given that you're posting in the Express Edition forum, I assume you didn't pay for a compiler, and this tool is probably outside your price range ( it costs a LOT more than visual studio does ). It's also a bad idea, IMO. If you want safe code, you need to use C++, simple as that. There are things you can do to try and help the situation, but you can't stop people from de ...Show All
