• Visual Studio Express Editions Visual Studio C# problem

  Hi All, I have an issue with Visual studio 2005. I add a private ArrayList arrayList to my main form class. This arraylist is used to dynamically change collection values of certain toolbox items used on the form. However, after co0mpiling a couple of times, Visual Studio removes all statements that include 'arraylist' except for the the declaration of arraylist. This has happened many times now and I find myself replacing the same lines of code continuosly. I htink that this is pretty strange and I am wondering if anyone knows how this can be resolved so that 'arraylist' isn't removed Thanks, Rachad Keep the files separate. The code in the Form1.Designer.cs file is modified by Visual Studio a ...Show All

• SQL Server TimeOut Expired!------How to handle this?

  The following program is to write a whole year's month,day,weekday in a MSSQL table. But somehow, for many times I have tried, but each time I got only part of what I intend to get: the whole year with 12 monthes, instead, I only got 3 or 4 months' content in the table. Can anybody tell me how to handle this The error is: System.InvalidOperationException: Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached. at System.Data.SqlClient.SqlConnectionPoolManager.GetPooledConnection(SqlConnectionString options, Boolean& isInTransaction) at System.Data.SqlClient.SqlConnection.Open() at database.DBCl ...Show All

• Visual Studio Express Editions Label

  I know theres a way to chage the text of a label while a programs running, something like text.label ="something" but i dont remeber how... It depends on which technology you are using. C++/CLI does it like: labelVarName->Text = "Text"; MFC does it like: staticClassName->SetWindowText("Text"); Windows API is: SetDlgItemText(hDlg, nDlgItem, "Text"); Thinking about it, since this is the express forum you wont need the MFC version. ...Show All

• Windows Live Developer Forums v3 gives an error; v2 does not

  When I call CampaignManagement.GetCampaigns(..) and reference to v3 wsdls, I catch this error: "There is an error in XML document (1, 552)." If I change all the references to v2, it's smooth sailing. The context of the call itself is some of the very first I wrote and has worked countless times before. Why do you think there is a difference and what do you advise -Tal Tibor, Thank you for confirming that this now works for you. I can't say why dotnet 2.0 worked for you when 1.1 did not... it could have been some odd configuration issue. Please dont hestitate to reply should you have any further questions or comments; or if I can be of assistance in any other way. Best Regards, Jason ...Show All

• Windows Forms MessageBox doesn't do anything on Application Exit

  i'm not sure why this is, maybe some of you guys can help me out. i have an MDI application. i have a MDI child inside the parent. i click the "X" of the MDI window to shut down the application. i have a call to MessageBox.Show in the Dispose(bool) method of the child. nothing shows. i put a break point, and i can actually step through it and it hits the line where i show a message box, but it passes through it and nothing comes up. i need this functionality because when the application closes i need to ask a question for each MDI child. it works fine if i close the child inside the MDI parent. is there some event i can listen to or something like that the ApplicationExit event occurs too late. thanks! ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Screen layout for 360 games

  Dave made a blog entry yesterday pointing to another blog entry that should be a must-read for all of us considering doing 360 development. I know I had no idea about what he talks about. I'm a bit more guilty than you. I've had several people mention that (Yes, ZMan, I remember you telling me that) and I STILL didn't listen. I need to make a mental note to start following a few more of these recommended best practices. Having that helper class should go a long way to reminding me though. Nice job on pointing it out Dave and great job in providing such a wonderful resource Mr. Anderson (boy, what a name to have and be a geek! bet he doesn't get tired of those Matrix jokes...) ...Show All

• Architecture Windows Service OR Win App

  I have been told to write a windows service which 'periodically' checking for messages and application updates from the web service. The user has the choice to download updates and messages automatically or to be prompted to download them when they are available. Note: A Message may contain documents. Now my question is is it the right approach to do this using a windows service or windows app/form. Please help me out on this. Thanks kash In my opinion, there should not be any problem while using win service as you are going to check for it periodically and the process will be running in background. You might need to think of more while trying to prompt as Windows Service does not support UI. ...Show All
