• .NET Development Slow connection - Operation timed out

  I have a application written in C# which connects to a web service thorugh https, sends a SOAP envelope and get's a reply. My problem is that during the file transmision the application locks(freezes) 'till I get some king of reply and then displays the results. That's my first problem and the second would be that if the connection is slow I get a reply saying that the operation timed out no matter if a set or not a timeout value for the proxy.

• .NET Development .NET Framework - hotfix. Can I discard the original Framework?

  I don't know where else to post this, but I just received an automated update hotfix for my .Net Framework that is 1,114 megs...this is in addition to the original .Net Framework that is also 1,114 megs. That's taking up too much of my disk space. I'd like to remove one of them if I can, but I don't know anything about the pros and the cons. Can I just remove the original and use the hotfix in it's place Thanks, Paul The update was pushed to you via Windows Update because it was rated as an Important security update.  In general you don't want to disable accepting updates since it will leave your system vulnerable to attacks ...Show All

• Windows Forms populating grid on the fly

  hi friends am trying to populate data grid on the fly in button's click event. my sample code is SqlCommand myCommand = new SqlCommand ( "select * from task" ); myCommand.Connection = conn; myCommand.ExecuteNonQuery(); grdTask.DataSource = myCommand; grdTask.Refresh(); this is not loading any data or returning any error any ideas . am using VS 2005 and C# Thanks 1.

• Visual C++ VS2005 and function GetProcessMemoryInfo

  Hello All, I had some old code that ran perfectly in VS 6.0 and used the function GetProcessMemoryInfo located in psapi.h and paspi.lib. This was on a 32 bit machine.

• Visual C# Raise an event from a User Control.

  I created a user control, let's just say this user control "Simpsons". "Simpsons" control has some other controls on it, let's call them "Homer", "Marge" and "Bart". "Simpsons" should raise a "Click" event, whether the user clicks "Simpsons" itself or "Homer" or "Marge". How can I achieve this Thank you for your help! P.S : The names of my controls are NOT actually "Simpsons","Homer","Marge" or "Bart." :-) It had written an article to do this long back. You can read it up. BTW: I am not sure if the sample code will work as-is since it was written in .NET v1.0 Beta2 [ http://www.mastercsharp.co ...Show All

• Visual Studio Tools for Office Make smart tag recognizer stop recognizing text after surrounded by XML tags?

  Hello, I am using Smart Tags to replace a regular expression string, say xyz, with the following: <bill>xyz</bill> (i.e. not the string literal "<bill>" and "</bill>", but actual XML tags using InsertXML method ). This works fine, but the only problem I have is once its replaced, the new result "<bill>xyz</bill>" still has the smart tag underline beneath it, so the user can do this recursively. Once the string has been replaced, I no longer want it to be recognized! How can I accomplish this I tried using the Zero-width positive lookahead assertion grou ...Show All

• Visual C# Executing a method of a class as soon as the class is reffered!

  Hi, It would be great if someone could provide me a solution to my problem. I am creating a class ( say the class is named as Checkconnection.cs) that would check if my system is connected to the internet. I need to continously check for an internet connection and if there is a connection I need to carry out the required operation. Now imagine a third party is using my class, Checkconnection.cs in another application (say HisApplication),and lets say he has written the code as obj.Isconnectedtointernet(); it will check for the internet connection only when it encounters the code "obj.Isconnectedtointernet();". My problem is tha ...Show All
