Hi,
I am doing an application in WPF. The application is in maximized state with no minimize and maximize box.However on double clicking over the tool bar, the application got minimized. I have to always keep it in maximized state that would work in all resolutions. Please help me.

You can have the line Me.WindowState = FormWindowState.Maximized in your
Form1_SizeChanged event.

Hai Everybody,
I have a dataset and I am binding the same to a combo box in windows application.
I want a item named "Select" to be in the top and it should be the default one.
Can any one tell me how to add an extra item after binding the combo box with the datasource.
Thanks in advance.

You can just add it in the form designer and switch on AppendDataBoundItems.
Or you'll have to go with adding it after with ddl.Items.Insert(0, "Select...");

Thanks a lot.
Actually I have set the text as "Select", but I have forgot to change the drop down style.
Best Regards,

Why have you deleted your original message? You got an answer to your question, so what's the problem?
It's considered rude to do this.

I am running msinfo32.exe programmatically in my application to output the system information. When this runs especially on windows 2000 sp4, it is scanning the floppy drive and resulting in some noise.
How can i avoid it from scanning the floppy drive?
Thanks.

Hi all,
I have to make a library to convert the Color from Lab value to RGB value. However, it requires an algorithms to do so.
I read some documents, it mentioned that the steps should be
1. Lab -> XYZ
2. XYZ -> RGB
I really have no idea what the calculation should be.
I hope to fine some example from here, as I think some of the experts
must have done the same things, or have this experience.
Could you please provide me some examples? Thanks Thanks ...

I am trying to call the following method from a library to an exe file using a delegate, can anyone help with the following:
namespace xxx
{
public delegate void DelegateGetMethodA(Int32 b);
class Library1
{
MethodA() // How do I call MethodA here using delegates
}
}
namespace xxx
{
static class Program
{
[STAThread]
public static void Main()
{
ExecutionClass exe = new ExecutionClass();
DelegateGetMethodA GetMethodA = new DelegateGetMethodA(exe.MethodA);
}
}
}
namespace xxx
{
class ExecutionClass
{
void MethodA(Int32 b)
{
a = b + c;
}
}
}
Thanks in advance,
Michael

create an instance of the delegate
like
DelegateGetMethodA _delegateGetMethodA = null; in the class where you want to invok the method.
Then set the method to the delegate
Library1 _library = new Library1();
_library.SetDelegate(exe.MethodA);
In the SetDelegate methods assign the value to the _delegateGetMethodA
Then you can call the delegate
_delegateGetMethodA (parameters);

Hi Guys.
I have been trying to make the following happens, but as a newbe to c# I beleive I need some help out there.
I made a (C# :: MDI Application) , as we call it in delphi, that creates a child with a blank white image on it.
What I need to do is to create an image(a small image that differs from that big white one), every time the user clicks on the first big white image, and put this small image on the position of mouse clicking...
Here the program must store the names and positions of those small images in an array, and update this array every time the user moves one of the small images....
Does any one know how to make this work...
Any Thoughts could Help..
Thanks in advance.

Yes, create a class, inherit System.Control. Overide the OnPaint, OnPaintBackground, and OnClick OnMouseMove events. Add code as necessary.

Dear Sir,
Forgive my ignorance, but as I said in my question, 'I used to be a delphi guy, I am just a newbe to c#'.
Based on this fact I really can't see or know how to use the tips you mentioned.
Could you be more specific please. I am quiet sure that you have the answer for my question<<MY HUGE TROUBLE>>
Thanks a lot for your patience and understanding..

Beyond pointing you in the right direction there is not much else I can do beside writing the application. I would recommend a good thick book on C# and then you will be able to use the MSDN reference to get the immediate answers.

Dear Sir,
I thought you would say something like this.
And I would like to thank you for your patience.
I am already surfing in a HUGE book on c#, and all I wanted is a little help on starting.
Again.
Thanks so much ...

I have a question for all the experts here.
In visual studio, I find a lot of tools that help you. For Example Gridview, you can use the SqlDataSource to do all your Select, Insert, Update, Delete functions.
So what is recommended? write your own code in different classes and methods or use these tools?
My personnal opinion is that the wizard clutters up the aspx page, while your code reside in aspx.cs which is neater.
But of course wizard is faster and more convenient.
So what do you advise?

The wizard is also less effort, and probably less effort to run again when your schema changes.
If you are worried about tools making your life too easy then use notepad
