Probably not. Most applications won't save the key itself anywhere you get easily find or get at. If stored, it'll usually be encrypted, but every application is different.

I tried to find an article on how to manage IIS (creating/deleting web sites and the like). Anybody has a pointer to some useful information on how to do this?

My application will be running on a slow PIII-400 machine. And the application needs to display a lot of pictures.
At a point i need to bring up a dialog, covering the pictures. When the dialog hides, the covered form cannot refresh fast enough so that it looks very choppy.
This program is gonna be used in a restaruant, it cannot give impression that the program suk, is that any way to make sure the background has been drawn, before the foreground(the dialog) hides?

Not really. For such a slow machine, you're probably going to have to back-off on the use of background images. This is especially true if you're using images larger than they need to be and scaling them down to fit inside the form and using a lower end video card.
Keep in mind that your app is going to have to have it's own minimum system requirements. You can't just put something together and get good performance on one machine and expect that same performance on lower end hardware.
There's a bunch of optimzation techniques, but what to do is very dependant on your code and form design.
Scale images down to the size you need for the form. For example, don't use a 1280x1024 image on a form that's only 320x200. You'll waste too much time loading all the extra data you're never going to see. Along the same line, if you can get away with a 256 color image, instead of 24+ bit images, do it! The less you have to load, the better.
Don't use an exessive number of controls on a form. Controls are very expensive to create and place dynamically. Also, calling all the Paint methods for those controls takes a while too. The less you have to paint, the better!
... There's lots of things you can do, but what you do depends heavily on your code, and more importantly, your design.
You can start by skimming through Improving .NET Application Performance and Scalability[^].

Hi all! I am getting an invalid cast error in the constructor of a form. There is no code in the constructor except for the InitializeComponent(); In the debugger, it goes through each line of the IntializeComponent method, returns, then pops out the error? What am I looking for here?
Thanx!

Is it on the return of the constructor?

It is after the return of InitializeComponent()..the form builder if you will. After goes through th last line, returns then invalid cast error.
Thanx for the quick reply!

Is it ON the return from InitializeComponent() or after (like when the constructor is exiting). Do you have a destructor (or similar) performing some type casting?

It is inbetween the return from the contructor and empty space..the debugger goes to the //TODO...comments first line and the very next step I get an invalid cast operation. I think I may just wipe it and start a new form.
Thanx for the help though!

This is not possible. Something tells me that your source code is not in sync with the compiled code.

The if clause should work. Check in the debugger, if Form1_KeyPress is called, maybe you forgot to subscribe to the form.KeyPress event handler?
this.KeyPress += new KeyPressEventHandler(Form1_KeyPress);

Hi
I want to know how can i use the visual studio Query Builder I think it is in Microsift.VSDesigner assembly but I dont know how to use it.

Hi all,
I'm declaring a property...
<br />
public int Number ()<br />
{<br />
get <br />
{ <br />
return myInt; <br />
}<br />
set <br />
{ <br />
myInt = value;<br />
}<br />
}<br />
and I'm getting a build error. The complaint is coming from the get and set keywords, it is asking for a semi-colon (;) to be placed after each. I also believe that value should be a keyword (i.e. highlighted by the ide) which it is not.
Can anyone help because I thought this was pretty straightforward.

Properties are declared without the brackets. The compiler thinks you're trying to declare a function.
Should be:
public int Number {
get {return MyInt;}
set {myInt = value;}
}
Share and enjoy.

public int Number
{
get
{
return myInt;
}
set
{
myInt = value;
}
}
try this.

Properties don't need brackets ( and ) in the method header
