• Windows Forms closing form, and all modals on top of it

  Hi, I have an application that connects to a server. The server might send an event that should cause my app to go offline. However, the user could have at that particular moment a wizard (in the form of a modal dialog), which also could have other modals or message boxes on top of it. When I receive the event, I want to be able to close the wizard along with all its modal 'children'. There was a solution, in having the modals listen for a particular event, and close when they received it. However, as I said, I could be using message boxes also. So I can't have those listening for the event. I need something like running through the forms of my app, and see if they're on top of the given form. Then call Close() if that's the ...Show All

• SQL Server Usage-Based Optimization

  Hi all, Im working on AS 2005. The users will use Excel 2003 pivot table to query cubes. The performances look fine so far but I read that the Usage-Based Optimization is a powerful feature from AS 2005. Do you think it will be a good idea to implement this optimization Regards, JL Have a look at this previous thread: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=783773&SiteID=1 HTH Thomas Ivarsson ...Show All

• Visual Studio Express Editions Need a bit of help creating a C project

  What steps do I take in creating a C project in Express. I would think that one should be able to just create an empty project and then add a file with a .c extension but I'm having problems. One way I tried was to go into a projects "Properties" click on "C/C++" then "Advanced" and change "Compile As..." to "Compile as C code". This works but there doesn't seem to be an easy/nice/simple way to start off in C without creating a bunch of c++ stuff like cpp files in Express ... or is there Thanks in advance. Ayman points to some useful links, though you may have stumbled on a different problem.  1. For making simple C/C++ programs, make sure you start with the VC++ File | New .. ...Show All

• Visual Studio Visual Studio Crashes on Computer Standby

  Has anyone had this problem with Visual Studio.NET 2005 Professional Edition: When I leave the computer for a minute I have it set to go back to the login screen for security reasons (using Windows XP SP2) Every single time I return back to my computer, I get the error that says: "AN ERROR HAS OCURRED IN VISUAL STUDIO. IF YOU DID NOT SAVE A FILE IT MAY BE LOST. SORRY FOR THE INCONVENIENCE" The only solution I could come up with is turn off the screen saver or shut down visual studio when I leave the pc for a minute. Both are pretty annoying...... Thanks Thanks Paul, much appreciated. There are some known issues about this, which maybe (but do not quote me) addressed in SP1 for VS2005 - it's currently in be ...Show All

• Visual Studio Team System Object Moved Error in Response from Web Server during Web Test

  I created a New Web Test and recorded a script. The script hits my login page with a username and password. When I record it works fine. However when I playback the script with 1 user (It is passing the correct username and passworD) I get responses stating "Object Moved" Please click here. What does this mean Also, we call our COM Object on login from ASP which I can see being instantiated when I record but on playback, the COM never runs... Any ideas Also, this might be a simple example of a page redirect. When you enter a URL in the browser that causes a redirect, the browser receives the "Object moved" page but does not display it; the browser shows only the final page in the redi ...Show All

• .NET Development Detecting network related SQL errors

  In my application, I want to trap SqlExceptions that occur as a result of periodic network issues between our offices. If an SQL query fails as a result of one of these network-related issues, I sleep a predefined period of time and try again later. Note that I don't want to sleep on any SqlException as it may be a real db-related problem (in which case I rethrow). To accomplish this, I've been looking primarily at SqlException.Number (which the docs indicate correspond to a row in master.dbo.sysmessages ). However, I see that it sometimes returns values from other domains. For example, it can return: ERROR_NETNAME_DELETED = 64, ERROR_NETWORK_UNREACHABLE = 1231 as well as: System.Net.Sockets.

  Having trouble passing to and from date parameters to an MDX report. I've set up query parameters that work when the report is rendered. We also have default values set that are getting passed to the report upon rendering, but cannot pass parameter values from an application to the report. The parameters are string types in the form yyyymmdd. We've passed strings such as 20040101 and also tried using the default values from report manager which are set as [CALENDAR].[Hierarchy].[YEAR].&[2004].&[8013].&[24037].&[20040101].
