All of the code can be run using standard .NET Framework references.

Google, or search MSDN, for smoapplication. From there you will find links to information that will help you to get it running.

As part of the process you will have to add references to the following assemblies:

// SMO namespaces
using Microsoft.SqlServer.Management.Common;
using Microsoft.SqlServer.Management.Smo;
using Microsoft.SqlServer;
using Microsoft.SqlServer.MessageBox;

The code comes from one of the SqlServer samples downloads, from MSDN.

Memory leakage in c# multithreading application windows service application

I have a windows service multithreaded application for indexing purpose which have six threads. It is working fine except memory leakage. Actually when the service is started, then the service is consuming 12,584kb memory, after some time it is taking memory of 61,584 kb. But after indexing process is complete it is not releasing memory. I need it come back to its previous position after the indexing is complete, that is it should take the memory with which it started e.g. 12,584kb in this case. I have used garbage collection but it is not doing what I want.

Can anyone please help me?

Are you sure it's actually using that memory. Task Manager reports the amount of memory a process has reserved, not how much it's using. If that memory is needed elsewhere and your app isn't using it, it will be reclaimed.

In case it is, make sure that any objects you are using that have a Dispose method have that called once you are done with them [Edit] or better still, if possible use using blocks [/Edit]. If you are using any PInvoke, make sure you are releasing any unmanaged resources too.

Task Manager is telling you how much memory is reserved for the .NET CLR your app is running under. It's entirely possible for the CLR to reserve that much memory even though your app is not using it. The reason for this is because the CLR watches what your app has done and since it already allocated a large amount of memory, it'll keep the memory around in case your app wants it again. It's fast to allocate an object with memory that is already in the Managed Heap than it is to wait for the CLR to request memory from Windows, add it to the Managed Heap, then make the allocation.

webbrowser stealing focus

Hello,
i am using a webbrowser control on my form together with textboxes. What i need is that when i load the form the cursor will be in textbox, but instead the webbrowser "steals focus". I have tried using the Focus() property for the textbox in just about anywhere now but it still wont work. Also i have tried creating event handlers for webbrowser's different events (GotFocus, Validated etc) but nothing seems to work.

The only thing that worked was the DocumentCompleted handler, which can make the cursor go to the textbox but not when the form loads, which is strange, since i have the browser go to a web page when the form loads (after InitializeComponent).
TY

What you need to do is set the Tab Order. This indicates which controls get the input focus in which order when you press tab to switch between them. The lowest tab order control gets the focus first on form load. Simple.
Tab order is initialy assigned in order of control creation, so if you create your browser first, then create the textboxes, the browser gets the focus.

I forgot to mention it, but tab order has been set properly. The cursor still goes to google.com's search bar (google.com is the site being automatically loaded into webbrowser at startup).

Just tried it, with a browser docked in a panel, and a textbox with button outside the panel. Set URL to "http:\\www.Google.co.uk" in design properties, TabIndex is Textbox = 0, button = 1, panel = 2.0
Works fine, Cursor in textbox on form load. How is this different from yours?

Its not different. When i do the same thing, the cursor automatically goes to webbrowser Frown | :(

I just discovered that the problem exists only with some pages (google, orkut, youtube, hotmail etc). When i use any of my local sites (.ee) then it works just fine.

Why is that so? google and microsoft using some fancy scripts?

Prevent the ^ character from beeing entered in textbox.

How can I prevent the ^ character from being typed in a textbox? The problem seems to be that the character is not added before another keydown/keyup event.

For some other keys I used the following code to prevent them from being typed:

void textBox_KeyUp(object sender, KeyEventArgs e)
        {
            if ((Keyboard.Modifiers & ModifierKeys.Alt) == ModifierKeys.Alt)
            {
                if (e.PlatformKeyCode <= 12)
                    e.Handled = true;

                switch (e.PlatformKeyCode)
                {
                    case 226:
                        e.Handled = true;
                        break;
                }
            }
            else if ((Keyboard.Modifiers & ModifierKeys.Shift) == ModifierKeys.Shift)
            {
                switch (e.PlatformKeyCode)
                {
                    case 52:
                        e.Handled = true;
                        break;
                    case 186:
                        e.Handled = true;
                        break;
                }
            }
        }

However, this does not work for the ^ character.

Thanks for help!

Couple of things:
1) KeyUp is probably not a good place to disable keys, as KeyPress happens repeatedly before KeyUp occurs. Try handling KeyDown, KeyPress and KeyUp with Console.WriteLine in each to show the flow of events.
2) If you are going to use magic numbers then comment the damn things so the next poor sod stands a chance of understanding what you are doing:

// Disable '%' key
case 52:

is a lot more useful than

case 52:

By preference, use '%' instead of magic numbers, or constants with sensible names, or even "Keys."
3) Use KeyPress to disable your code:

private void textBox_KeyPress(object sender, KeyPressEventArgs e)
    {
    if (e.KeyChar == '^')
        {
        e.Handled = true;
        }
    }

Thanks for the replies guys. Sorry, but I forgot to mention that I work in Silverlight. I can't get to the KeyPress event. Only KeyDown and KeyUp.

Thanks again.

Hi everyone.

I'm having an error in my application that is confusing me.
The error is this one:

Could not find a part of the path "C:\CrkBusinessplatform\Aplicacao\Publico\sistemas\ccs\CRK.Monitores\sistemas\ccs\CRK.Monitores\monitor_arquivos\xslt\ACCS001.xslt"

Here are the facts: The correct path would be C:\CrkBusinessplatform\Aplicacao\Publico\sistemas\ccs\CRK.Monitores\xslt\ACCS001.xslt -> A part of the path is coming twice.
The archive ACCS001 is in this correct path.

The code line of the error is like this:
xslt.Load(Page.Request.PhysicalApplicationPath+"/monitor_arquivos/xslt/ACCS001.xslt");

I'm using .NET 1.1 on IIS 6.
The folder CRK.Monitores is a virtual directory in IIS. So the code should return the right path, right?

Oh, one more thing. The DLL of this page is the same here and there(I have checked it). And the error does not occur here.

Thanks in advance. Smile | :)

Have you tried echoing Page.Request.PhysicalApplicationPath to confirm that what you think it outputs is what it actually outputs? To me, this looks like you're making a false assumption about the returned value.
