Re: Hanlde Event when C# exe is aborted abruptly

Like Dave and originSH said, the purpose of the task manager is to stop a task/process pretty much in it's tracks. You can try the OnClose method, but it might not do you a whole alot.

Letting task manager do it's bit by shutting down the app with no intervention done by the app is what should be intended. Nothing more irritating than telling task manager over and over to kill a process because it won't go away.

Hi Dave,Paul and originSH,

Thanks a lot for your comments.

Let me explain my actual scenario,

I have a C# Windows EXE which will call my Webserive hosted in another Webserver asynchronously.

We have an UI interface which will call the above mentioned C# Windows EXE. when EXE gets abruptly aborted from UI Interface, my webservice still running in webserver machine.

Any options or methods to stop my webservice when my EXE stops abruptly?

Pls help me out.

Thx

Quick question involving xml deserialization and strings

Hi, I recieve a chunk of XML as a string that i want to then deserialize, but none of the XmlSerializer.Deserialize overloads accept a string as parameter, mostly only streams, textreaders or xmlreaders. Surely there has to be a quick way to convert a string to one of those formats?

The streams live in System.IO, have a look there.

I don't think there's a smart way of doing this.

You could allocate a byte array, create a MemoryStream on it, and then write your string to the memory stream. Then you can deserialize from that.

using System.Beer;

Off the top of my head, you could try this:

public T FromString<T>(string serializedObject) where T : new()
{
  XmlSerializer xmlSer = new XmlSerializer(typeof(T));
  StringReader sr = new StringReader(serializedObject);
  XmlTextReader stream = new XmlTextReader(sr);

  try
  {
    T obj = (T)xmlSer.Deserialize(stream);
    return obj;
  }
  catch(Exception ex)
  {
    // Log ex...
  }
  finally
  {
    sr.Close();
    stream.Close();
  }
}

Making a simple button

Is there a way to create a simple button with no xp skins or anything? (like the buttons in minesweeper)?

I tried to disable UseVisualStyleBackColor but it still shows a blue rectangle on the button after it's been clicked.

You might find that one of the various FlatStyle options on Button does the job. Otherwise just draw the button yourself in an overridden OnPaint.

If you're using Visual Studio open up Program.cs and remove the line Application.EnableVisualStyles(); inside the Main function. This is what tells the app to use the Windows XP theme; doing this will remove the visual styles from every control in the app.

Custom Validators - Basics

I have a web page with 3 date fields. One is required, the other 2 are optional.
These will be written to a database once the user clicks save.

Should I use the in-built customvalidator method? What about spaces?
Should I write a separate validator for dates using the dreaded REGEX?
Can I validate them all using FindControl in a ForEach loop (the id's all begin 'dt****')?

Any advice welcome.

Cheers

Use the custom validator - there's a method on the DateTime class called TryParse. This is a great way to check to see if the date is valid. Also, use a required validator on the date that is required.

Well that's a shame, but who precisely was this aimed at? There are some excellent articles here on CP about implementing Undo/Redo - perhaps they might be of some assistance.

The web service will be running under the heavily curtailed permissions of the ASPNET worker process. You need to grant access to this user for the queue.

Gridview : how to get an "Excel Freeze panes"-like behavior ?

Hi all,

I'm writing an intranet application using ASP.NET 2.0 and C#, and I have long gridviews (lots of rows, and the users don't want paging), but many users asked me to have a feature like "Freeze panes" in Excel : do you know a method to have the first row (table header) keep on top of the page (and top of the window) while scrolling in the page ?

Thanks !

Seriously? Did you check out the members on the class? That link was to the main page for the class, the links at the bottom provide more information such as details on the Members of the class.

If you had "StandardOutput", "Start" and "GetProcesses" are pretty obvious.

GetProcesses will retrieve a list of all running processes from which you can get the one you want. Or you can use Start to run it if it's not already running.

Then StandardOutput gives you access to the output stream.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
