I disagree in part, this kind of help would be perfectly good if the OP had shown some ettiquette with his request.

I was also in a bad mood at the point i replied earlier - could you tell Big Grin | :-D

VS2005 - vshost threads

V.15-Mar-06 23:48

15-Mar-06 23:48

What's up with the appname.vshost.exe threads that are executed whenever you fire your app?
I've tried to kill it, but it just keeps reappearing.

What does it do? I get a runtime error in my app saying that my progressbar is already used by another thread. (presumably the vshost one, 'cause my app isn't running)

I also can't figure out the reason for 2 exe's instead of 1? Confused | :confused:

thanks!

Hello,

I use my own listview control. After a drag&drog, I lose scroll position. I backup scroll value, but after drag&drop, I call the SetScrollPos function, the scroll move, but not list items, how to go to the right items position ? May be use ScrollEventType.SmallDecrement until to go to the old position ?

thanks

I need to show images and text pages in a document viewer.
In windows applications we can view the images in picture box, without caching, ie when we view the doc in any browser we cannot copy it.

So I need a control like windows picturebox in asp.net.

pls help me in this regard.

aspx's page_load firing multiple times

livez15-Mar-06 23:18

15-Mar-06 23:18

Hello

I have an aspx page with a number of controls, including a few ascx usercontrols. Ive come to realize that the page_load event for this page fires several times every time a postback occurs. The number of times it fires is different depending on what triggered the postback, for one button it may be four times, for another 6 times. Also, IsPostBack is set to False for almost everytime, and then suddenly for page_load nr 4 out of 6 its set to true, for an example. I cant seem to figure out what makes it fire so many times, or why IsPostBack is set to False, or why all of a sudden its set to True and then back to False.

Does anyone have an idea what the cause of this might be?

/Regards Magnus

Reflect entire Class Hierarchy

Hello
Is it possible to analyze a complete class hierarchy using reflection ? I found some samples on MSDN which worked well, but they all looked at one class only, I need to read properties and custom attributes from the parent classes too. I know it works in Java, so there might be a way to do so in .NET too…

I’m creating a generic persistency component for academic purposes.

Simple enough; once you have the type of a class, use the BaseType property to get the parent's type. For instance, try

Form f = new Form();
Type t = f.GetType();
Console.WriteLine(t.BaseType.ToString());

HTH.

Cheers,

Yes, you have to handle two events in your form, DragEnter and DragDrop.

datagridview cells

CandyMe15-Mar-06 21:32

15-Mar-06 21:32

I have a datagridview which allows users to enter new values for each column. But what I would really like is to prevent the user to add value to other columns if column MSISDN is still empty. which means, user must FIRST add MSISDN value before filling up the rest.

Is there anyway where I can prevent the cursor or prevent setting focus to cell before anything else.

THANKs!!!!

simply use "CellValidating" event for other columns.
in this event check whether if your MSISDN column is empty then set cancel to true.

C++ guy missing pointers

Hi,

I have a problem in C#, which in C++ i would solve within seconds using pointers/references Smile | :)

But how to solve this in C#

I will try to explain my problem with an example:
I have two classes Data & Formatter

public class Data
{
  public string strText;
  Formatter formatProtocol;
  public Data()
  {
    formatProtocol = new Formatter();
  }
}

public class Formatter
{
  public Formatter() {}

  void FormatNow()
  {
    //
    //  I need to format the parent object strText member
    //
  }
}

How do I let the Formatter change the strText member ???
How should i solve this if it wasn't a string but a ValueType ?

OK, my apologies,

you can create a getter/setter method (more Java based) or a property (C# based)

This is exactly the concept of incapsulation.
so to get to a private member of your class you can do this:
C# based:

public string AStringName{<br />
  get{<br />
   return theprivatemember;<br />
  }<br />
  set{<br />
   theprivatemember = value;<br />
  }<br />
}

This allows you to check if value has correct value (according to your needs) before actually setting them.

eg.:

classinstance.AStringName = "Hello CodeProject!";

will result in the theprivatemember = "Hello CodeProject!"
You can do the same for int, arrays and even objects.

good luck!
