Re: Problem in connect with Remote server?? - C# Discussion Boards

This is part of my program that activates the mouse movement sensor once a checkbox is ticked.

What i want is for it to be activated by default.

I've tried editing the checkbox in designer view of the form, setting the value to true, but the mouse movement is still not picked up until the checkbox is unchecked then rechecked.

Im new to C#, im assuming it's something to do with "CheckedChanged"....?

This is the code for the checkbox:

private void checkBoxOnMouseMove_CheckedChanged(object sender, EventArgs e)
        {
            if (checkBoxOnMouseMove.Checked)
            {
                HookManager.MouseMove += HookManager_MouseMove;
            }
            else
            {
                HookManager.MouseMove -= HookManager_MouseMove;
            }

Any help at all would be greatly appreciated Smile | :)

You should add this line in your form load event.

if (checkBoxOnMouseMove.Checked)            
{                
HookManager.MouseMove += HookManager_MouseMove;            
}

This will attach the event during the load.

You need to add this into the form's constructor or Load handler too so the subscription is already active when the form loads.

HookManager.MouseMove += HookManager_MouseMove;

Where and what is the form's constructor or Load handler?

My code is made up of bits and pieces here and there, so i dont know it inside-out. Just a brief understanding.

[EDIT] - never mind, i have found it and got it working Smile | :)

Thank you so much for the help Smile | :)

Seems you are pretty C#-ignorant then, and just trying your luck at random. I suggest you do yourself a favor, buy and study a book on C#.

I do apologise for being new to C#.

I am interested in learning to write programs in C#, and am hoping to pick up as many things as i can through the questions i ask on this forums. Even if they are stupid.

I have my program working thanks to the help on this forum,

So again, i appreciate all the help Smile | :)

And i apologise for any future stupid/ignorant questions.

No need to apologize, everyone is new to something at some point.

However, rather than spending 100+ hours at asking 100+ questions and reading and testing all the answers, good and bad ones, you'd better take this advice[^]. And then ask more intelligent questions when they arise. Which we will be glad to answer.

No worries! Beginner questions are allowed, but real basic stuff should be known before being let loose with Visual Studio (or one of the Express Editions) and an internet forum IMO.

Don't be afraid to ask. A good book, and working through (and understanding) some online tutorials is a must though. We will happily help whilst you learn, but not hold your hand if you understand what I mean.

What on earth has any of what you've written have to do with C#?

To support such function:
Can draw three column a, b, c with the images.
User can use the scroll bar to control the column a,B
Column a and b are opposite. Column c is static.

User can draw 10 rows of column a,b to the column c.
then the program can draw the lines from the row of colun A to the row of column B.

Does anyonthe know the user control can do this? If I design this user control?
how to achieve it?

thks

I need one user control that can support user draw.

Column A Column B
A1 B1
A2 B2
A3 B3
A4 B4
A5 B5
A6
A7
A8
A9
A10

1.When user can select 3 rows of Column A and draw to row B2 of column B, three line will be created from a1 -> b2, a2 -> b3, a3 -> b4.
2.There are 200 rows in Column A, A1 -> A200. User can uses scroll bar to control which rows of column a to show.

AFAIK there is no control that does this, or at least I could not find one.

What you are describing sounds rather like a graphical database designer or query designer works.

If you google for c# database designer or c# diagram designer, you might well find something that you can get useful code from, or at least ideas.

It seems to me that you will need to build your own control, and if so I would suggest that you use ListBoxes for ColumnA and ColumnB. You will need to research Drag and Drop, and for drawing the links I would suggest that you create a class that contains the starting listbox, the item (A1, A2 etc.) from that box and the same for the ending listbox. Then when a link is needed create a new instance of the class and add it to a list. when your control needs to paint itself, you just iterate over the list drawing a line from the start listbox to the end listbox.
