I want to simulate a simple left mouse click that would be "pressed" after 5 seconds I clicked a simple button form.
enter link description here
I tried that way but it didn't work. Couldn't things be simplier?(sry I'm new here)
Unfortunately for a relatively low level operation like this, you'll have import the user32 WinAPI dll and do exactly what the answers in your link suggested. The only simpler thing to do is to use a library someone else built that wraps around the WinAPI, like http://inputsimulator.codeplex.com/ as suggested in this answer:

It's not 100% clear from your question, but this is all assuming you want an actual "click" message to be sent to your form. If you just want to simulate a click event on a control in your form, you can always just call the click event handler when appropriate!

I'm relatively new to C# and I want to know how can I press a key on my keyboard say the Q key and have it preform a list of functions?
I want to form a list of function under neath it. Anybody have any idea how to do this? thanks
//Something like this
if keyboard_down(Q)
{
//Do events here
}
I know this isn't the right function but that is basically what i want it to do. Winforms
You didn't mention which technology you work with.
I will assume that you are using Winforms.
In order to react to Key Press event you need to use Control.OnKeyPress - See here
See also this example which shows how to handle 'enter' key press
Depends on the way you want it.
Do you want them to fire while the form got focus or even without any focus to the form?
With focus:
Click your form in the form-designer and then go to the properties-tab. Click that little lightning bolt on top of it. There are a lot of events in that list. Double click "Keypress" and it will create an event automaticly and open the right code-snipped for you.
Depending on the focus you want, you can also mark controlls inside the form designer and then create the keypress event.
Without focus:
This would be a bit more difficultly. Here you would need to use a global keyboard hook to permanently grab pressed keys. Google for "c# keyboard hook". There are some examples out there.
So I'm making a simple program where I need to know if a button is pressed, and I need to know when a button is released after it's been released. I need to be able to complete an action when it's released
Winforms/WPF: MouseUp
WebForms: onkeyup
It's not really clear if you're working with webforms or winforms, but .NET provides event handlers for pretty much any event that could happen.
Here's a listing of the events Buttons handle.
The one you're looking for is 'Click'. This method will be fired whenever the user clicks on the button.
If you need to do something when the user pushes down on the mouse and again when he releases, Button isn't right for you. Many other objects implement the 'OnMouseDown' and 'OnMouseUp' events, though.
If you're talking about a winform and a keyboard press use the KeyUp event ( http://msdn.microsoft.com/en-us/library/system.windows.forms.control.keyup.aspx ) If you're talking about a mouse click use MouseUp ( http://msdn.microsoft.com/en-us/library/system.windows.forms.control.mouseup(v=vs.71).aspx ).
i want to FIre the button Click event When My Window is Loaded..
How Can i Achieve it in Wpf?
Create a single function with the shared behavior in your window, then call that function from both your loaded handler and your click handler.
As per this blog post in WinForms this was really easy by just calling PerformClick(), but in WPF you can do it with Automation, however as a commenter mentioned it's really easy if you have access to the button to just use RaiseEvent.
someButton.RaiseEvent(new RoutedEventArgs(Button.ClickEvent));
But as previously answered, if you only have a single handler that needs to be notified, then simply call that handler method directly.
You could use Automation to do it aswell - I've seen this suggested some places as the more flexible/robust method to use, but it seems a bit heavy weight to me compared to just calling the method you already have directly.
in you page_loaded event handler method, make a call to the click event like this:
_buttonName_click(sender, new RoutedEventArgs())
Trgger this event on Button whic u wanted to click
button.performclick();
How do I create a ballon tool tip with a close button.
I can show a tooltip:
TaskbarIcon.ShowBalloonTip(10000);
but I can't do the opposite:
TaskbarIcon.CloseBalloonTip();
Or even a way to show a close box on a Balloon Tip.
I saw this question posted on another site but with no (free) answer.
Thanks in advance
I was able to find a simple answer. Instead of using:
TaskbarIcon.ShowBalloonTip(10000);
I could use the second form of this function:
TaskbarIcon.ShowBalloonTip(10000,"Title","Message",ToolTipIcon.None);
This actually adds a close box to the balloon tip!
You might find this interesting:

This question has a helpful answer on closing the balloon.
Unless you need to hook an event on close, you don't need a button on the balloon, and even if you do, you can hook the balloon's click event to accomplish the same thing.
There are flags that allow you to do things like put an X in the upper right hand corner of the balloon so that the user can dismiss it. See here for more info:

I had a working program (Windows Forms Project) complete with buttons, labels, textboxes e.t.c. and the underlying code.
In an attempt to shortcut my work, I decided to add tab controls and move everything in my main form into tab 1 (cut and pasted).
As you can imagine it didn't work. I then got rid of the tab conrol and pasted everything back into the main form but the program doesn't work anymore.
Can someone tell me what's wrong please?
I'm working in MS V studio 2008 express
Thanks.
I have done this many times, but I usually just drag them into the TabControl. Maybe in the cut and paste operation your controls have become unwired from the event declarations.
The event handlers that you coded are still there. However, they are not associated with the control any more. I'm not sure if you're using VB.Net or C#, but the fix is the same - it's manual and tedious if you have a bunch of controls, but not too difficult. Here are the instructions for fixing a single button control, and you'll have to apply the concepts across the board.
These instructions are specific to C#. I can give you VB instructions as well as I've done this plenty of times.
Double click on the button to generate a new event handler. If the button is named Button1, the original event handler was probably called Button1_Click. Now it should be Button1_Click1.
Delete the Button1_Click1 function and compile. You'll get errors and if you doible-click on the error in the error pane it will take you to the form,designer.cs file to a line that looks like:
this.Button1.Click += new System.EventHandler(this.Button1_Click1);
Change this to
this.Button1.Click += new System.EventHandler(this.Button1_Click);
to point to the previously existing event handler, and the event handler will be fixed.
Possibly some of the events had code lost.
If you do it again it will probably work.
