Clip is just a property, so get and store its value before you alter it so you can restore it afterwards.

Probably, but you would have to use the Windows API and listen to/intercept/block system keypresses.

I wouldn't recommend this though as the user needs a way to switch to another task or close your program if something goes wrong. Keeping the mouse within the bounds of your app when it has focus should be more than enough. Anything else (and maybe even just this) would be hated by end users.

First of all, give your posts more meaningful names. 'Plz help me' doesn't give anyone any idea what your problem is. Read the forum guidelines.

Secondly, if you want to learn database programming, buy a book. Amazon[^] provides a list of suggested titles.

Which patterns are the best choice for business layer

Hi guys

I'm working on a website and have set up a number of stored procedures in my database and now I want to implement the layer in my code where I query my database (business layer).

So I was wondering if someone can give some input on what is the preferred pattern for my business layer. I've been considering the GOF factory pattern or builder pattern, is this a good choice?.
I rather not access my business layer directly from my front layer, instead I want somehow to abstact the creation of objects from my front layer.

Any suggesiton og hints??

Best regards

Custom Event Handler Problem.

Hi i want to extend MouseEventArgs class to add some property and info by define new class as follow :

namespace CustomEventHandler<br />
{<br />
    public delegate void MouseMoveExEvent(object sender, MouseMoveExEventArgs e);<br />
<br />
    public class MouseMoveExEventArgs : System.Windows.Forms.MouseEventArgs<br />
    {<br />
        Point m_mapScrollPos;<br />
<br />
        public MouseMoveExEventArgs(Point mapScrollPosition)<br />
        {<br />
            this.m_mapScrollPos = mapScrollPosition;<br />
        }<br />
<br />
        public Point MapScrollPosition<br />
        {<br />
            get<br />
            {<br />
                return this.m_mapScrollPos;<br />
            }<br />
        }<br />
    }<br />
}

as you can see in above code, my class inherited from MouseEventArgs class, but when i compile my app, the following error has shown me :
No overload for method 'MouseEventArgs' takes '0' arguments
how to solve my problem ?
thanks.

hdv212,

I think the problem is that MouseEventArgs is expecting a constructor that takes no params. So just add:

public MouseMoveExEventArgs()
{ }

Gareth.

If you want to add new constructor in derived class, there should be exact match of constructor in base class with same parameter. If not then there you have to make call of base class constructor explicitly .

So here i have made call to base constructor as following arguments,
you can change it.

public MouseMoveExEventArgs(Point mapScrollPosition)
: base(MouseButtons.Left, 1, mapScrollPosition.X, mapScrollPosition.Y, 2)

Hope it will helpful

Use a regular expression to split each line of text into its constituent parts. Regular expression support is provided by the Framework in the System.Text.RegularExpressions namespace.

See the following link[^] for more information on regular expression syntax in .NET.

pmarfleet suggested using Regular Expressions. Depending on the speed of the data coming in etc it might be suitable. However read through:
http://www.codeproject.com/KB/vb/WritingGPSApplications1.aspx[^]

Basically you can do some error checking, or the fastest way to split up the data into the various strings would probably be:

string[] individualStrings = sourceString.Split('$');
foreach (string individual in individualStrings)
{
    string[] parameters = individual.Split(',');
    // Now you have all the parameters split up into an array.
}

Hello,

I am just writing simple threading program in C# program, I am coming from VB.Net and just wondering why my WriteY() function has to be a static. I through this could be public or private.

Can anyone explain why it has to be a static.

You are calling the method from within a static method, Main.
