• Bubo Conversion Issue from VS.NET 2002 to VS.NET 2005

  All the classes are converted to partial and in the user controls the shared property has following error. "Reference to a non-shared member requires an object reference". Hi, Vishal VS 2005 uses partial classes to allow multi-source-file classes. Especially useful when separating the Form developer from the code behind the form. As for the shared properties, at each of these errors you should get an option to replace the object reference with the class name. Shared properties and methods cannot access internal data structures in the class, thus the error. Can you post an example Partial Public MustInherit Class workingNewHeaderControl2 Inherits System.Web.UI.UserControl Protected ...Show All

• reichard Centering one form inside another

  Another Newbie question.... How would I need to write the code to open form2 centered within form1 when form2 is selected from a menu item on form1. forms1 and 2 are regular forms not MDI parent or child. Hi, try setting Form2's StartPosition property to 'CenterParent'. If Form2 is opened from Form1's code, that should work... Andrej Or an alternative is setting both forms to center screen, which would in turn force the form2 to be centered inside of form1. I tried that and it didn't work, form2 still opens off somewhere else on the page. Is there some relationship I need to establish first to designate form1 as a parent and form2 as a child If so what's the code to do that Also ...Show All

• Ralf Kornmann Embedding Images

  Hi, For this little application of mine, I was thinking about embedding the image file within my solution in Visual Studio 05 as a resource, instead of accessing the folder on my hard drive. I followed the steps of embedding the image as taught in MSDN, but for some reason after I click on Project->Add existing item..I don't get the option of having the image as an embedded resource. Can someone tell me how to actually get the image as an embedded resource and subsequently use it in my code. Thanks.... thanks You don't need to bump so much. To add the image as an embedded resource, go to Project->Add existing item, as you said. Change the file type dropdo ...Show All

• Mark Ornelas Whats the equivalent of __LINE__ and __FILE__ in C#

  Whats the equivalent of __LINE__ and __FILE__ in C# I thought this hot-button issue would have been answered by now. But no one seems to have a good answer for this. I would love to see a solution which presents no runtime overhead. What about C# 3.0 does it address this issue If you want to log exception information then the exception itself should give you enough inormation. I think that if you want to use fault logging then you'd best use the System.Diagnostics namespace. Don't worry about the overhead. It's not that much and if you'ld only use for fault logging it doesn't really matter that it takes a little bit more time. Because the clr is a virtual machine, there's enough information you can query when thinks go wrong. In th ...Show All

• max-holz HELP - How to Read/Write a text file at the same time?

  How can I read and write a text file(same file) at the same time I'm getting an error of "this file is being used by another program".. I have a text log file and logs being written to it, simultaneously I want to read its concent and show them on a RichTextBox. How can I achieve this Thanks you can't... The best you can do is try to make your writes/reads as fast as possible so that there are no collisions - but it might be dangerous (your app may be prevented from writing by your reading). You'd have to create an alternative scheme - like writing logs to database, use TraceListeners or periodically changing your log file. charliebrown23, the way to go, ...Show All

• johnnyXNA Typing in Visual Studio 2005 Text Editor is extremely slow

  Has anyone else noticed that typing in Visual Studio 2005 is extremely slow   Whey I type it seems that the screen is always 2 words behind where my hands are.  It makes it extremely frustrating to get anything done. I'm mainly referring to C# code.  It seems like Intellisense is going nuts trying to guess every word I'm going to type and never actually prints the characters to the screen. Has anyone else experienced this   Is there an option I can turn off to get my text editor back ! By the way, I have a very fast computer with Dual 3.0 GHz Zeons with 3GB memory and everything else that should make "typing" very fast. I had the same problem - very slow typing - after I turned on wordwrap. I have now turned ...Show All
