• Windows Forms How to make certain variables global to all forms? (C#)

  I have this problem.. my main form class (MainForm) declares some variables that should be global, in a sense. Let's say my app, at startup, loads a bunch of user data.. into a list (List<UserInfo>). I want that list available application-wide. So if a preferences dialog opens up, and it needs to populate a ListView with that List<UserInfo>, it can. What is the best way to achieve this, in C# Hi there, Assuming you meant using Model-View-Controller (MVC) then I'll give you the quick 10 cent tour. Basically, your data abstraction, i.e. non-user interface type, exposes some (or all) of the data to interested parties and to notifiy those parties when the data changes. This is the Model part of MVC ...Show All

• Visual Basic display multiple languages in one form

  Hello I have a problem displaying more than one language in the same form. I have the data in access.mdb files in two languages (Arabic and Greek) and tried to display it using two datagrid views on the same form but was unable to do it. The data will be displayed according to the preset locale of the machine. I have tired to change the language by setting the UI culture as explained in the Walkthrough:Localizing Windows Forms but no luck. Can anyone help me with this. Thanks Batico Batico, Firstly, please make sure your operating system supports the multiple language in order that the .NET Framework support it ,too. Secondly, there is a file called AssemblyInfo that need to use the System.Reflection.AssemblyC ...Show All

• SQL Server Cancel does not cancel

  Hi, I wonder if Excel ASOLEDB9 is benefiting from cube partitioning Some queries are very slow and the Excel generated code look not that good I tried to pick some queries from SQL Server Profiler and run them in an mdx query window and I get syntax errors. This leaves me perplex since I have the feeling that people try endless queries through their Excel pivot cube, then, after a while they cancel the Excel query because it takes forever, then the server remain stuck on a high level of CPU usage. Is it because the syntax error or is it because they just ask for too much data Is canceling an Excel pivot data refresh enough to stop the server's query processing Yesterday night, it was so bad (100% CPU) that I had to restart the ...Show All

• Visual Studio 2008 (Pre-release) LINQ and Atlas

  Ok so what I am trying to do is have a form with a textbox for a search dialog. On keypress I want to query top 25 records and display them in a gridview, so as you type it refines the search etc. So I have hooked up all the atlas javascript methods etc but I am not sure if I am able to do this or not. Basically my webservice code looks like (generated with BLINQ): return from dom in db.Domains select dom; So this should return all my records (fine for now in testing) and my javascript receiving function does the following: function OnComplete(result) { var d = document.getElementById( "<%# grid1.ClientID %>" ); d.DataSource = result; d.DataBind(); } This results in an error of: System.InvalidOperati ...Show All

• SQL Server Performance issue when using Reporting Services?

  I have found indications in internet that the performance isn’t optimal in SSRS – both the CPU resources and the memory are consumed in a way that affects the performance a lot. The CPU resources are the same as SQL Server uses and if SSRS consumes a lot of these resources this might affect other parts. The memory can also be an issue since the SQL Server Standard edition is the one we uses and this is limited to 2GB RAM as I understand it. Are these “bad performance” indications true In some articles it is even pointed out that the SSRS should be placed on a Stand-alone server which thereby causes additional licenses. Is this really the case It depends how you look at it. Essentially what you have be ...Show All

• Visual Studio VS.NET C++ Debugger no longer loads DLL symbols when we attach to the host process.

  We've notice a problem recently whereby attaching the debugger to our host process no longer allows us to debug our DLLs. Repro: set a breakpoint in DLL then go to Debug-menu->Processes and attach to the host process. Result: the DLL's breakpoint is now shown with a ' ' (question mark) in it, indicating that the symbols were not loaded. This used to work OK, so we are wondering: what has changed Also, how do we fix this By the way, in VS.NET 2003, Modules Window, clicking on any of the modules and using the right mouse-button menu to reload symbols opens a dialog box which let's you browse to and the select the appropriate pdb file (it defaults to the correct folder), unfortunately select ...Show All
