Hello everyone,
How can I check if the mouse is inside or outside the client area.. To be more specific I have tried to make a calculation for inner controls but this do not work for the Form.
I am doing a drag-drop operation and I need to know when the user tries to drag something outside the main form. Is there a way to achieve ?
Thanks in advance and best regards !

Hello,
You could set a flag at the MouseLeave event of the Form.
Hope that helps!
All the best,

Thanks for your reply but it doesn't work.. I add a MouseLeave event which set the mouseInside booleand to false and a MouseEnter event which set the same boolean to true..
But interestingly when my mouse is over a control inside the Form the MouseLeave event is fired..

for which controls are you useing MouseLeave and MouseEnter events?
I think you should specify those two events for every control in you form.
Hope it helps

I use them hust for the main form, but definin those events for every control won't either work

Ohh,
sorry!
How are you draging a control of your mainform outside the mainform?

Well the exact problem is this. When the user drags a control the control moves with the mouse. When the user drops the control, the program makes some calculations and decide what to do with the control (return it to its original point, leave it where it is dropped, dispose the control etc.).
The user is expected to drag-drop inside the main form but as everyone know the user is the one who do not use the program as expected 
So when the user tries to drag the control outside the main form (sure the control stays inside the form but the mouse is outside and the left button is released outside) no calculations which are done in the drop event are made.

Hello,
So you have the possibilty to add the MouseLeave event additionaly to the controls.
Then you could set a flag if it is dragged and reset it if it was dropped.
If the mouse leave event is fired and the flag is still set, you have the possibility to validate whatever you whant!
Hope to help you now!
All the best,
Martin

I have similar problem. Don't we have any other solution other than adding MouseLeave and MouseEnter to inside controls.
Thanks

Hi
I have a C# Windows Application that copies a lot of data between different databases. All the copying is being controlled by a method in a helper class and this method is being called when the user clicks a button on the Windows form. Is there a way of showing the progress of this copying in a progress bar in the Windows form?
Thanks.

You could add an event to your helper class that provides some progress information and is triggered by the copy method. Before calling thios method, register to the event and adjust the progressbar according to the information provided by the event.

You could run the method inside of a BackgroundWorker. With the BackgroundWorker you can get the progress of the method through its properties and you can define how the progress...well progresses.

Hi,
For example, you can fill a Dataset using ADO.NET (Oledbconnection, OledbAdapter and Oledbcommand) and then set in the dropdown the property DataSource the dataset as value.
Example of the dataset filling:
//create the conn
OleDbConnection con = new OleDbConection("conection string");
//create the command
OleDbCommand cmd = new OleDbCommand("SELECT <field> FROM ", con);
//create the DataAdapter & DataSet
OleDbDataAdapter da = new OleDbDataAdapter(cmd);
DataSet ds = new DataSet();
//fill the DataSet
da.Fill(ds);

Hi all,
I have an application which will be installed on the user machine.
The application has two main parts.
First application checks for the new updates from the server and then invokes the other application using the dll.
The second application is what the user actually interact with.
The application minimizes to the system tray.
The user may close or minimize the form that is displayed.
My main objective here is if the application is running and the user again clicks on the Shortcut that is placed on the desktop.
The form that is minimized or was closed should be displayed.
How do i do this?
Hope i have put the problem properly to everyones understanding.
Thanks & Regards,
Pramod

Does the shortcut point to the actual application or the "launcher" application? Either way, you could check for the existence of the process first off and switch focus to it if you find it running. Something like
bool IsProcessAlreadyRunning(string processName)
{
Process[] processes = Process.GetProcesses(processName);
return (processes != null && processes.Length != 0);
}
If the above method returns true, you know that an instance of the process is already running. You could then use the MainWindowHandle[^] of the corresponding Process object to get the window handle and P/Invoke some Win32 API (Activate?) to bring the existing process' window into focus.
Hope this helps.
