I am extending an panel. Now my problem is , when i click on the panel it should get selected. I can any no of control to this custom panel. do i need to subscribe to all the mouse events such mouse down and set the focus to the panel in order to get selected.
In the custom panel, how can i aceive drag and drop in the panel Assume that i have inherited from a panel and i have internally divided the panel into 4 parts and now i place a control on 1 part and the user should be able to drag the control at 1 and place it 4. Can anybody sugges me how to acheive this.
Thanks 4 answering

Hi guys,
I have a single form to control my application and rather than use multiple windows it switches out the main panel depending on what view the user wants.
My problem is that its not very effective and wondered if you can point me in the right direction to get a flicker free app.
Should i go with this idea or is there anotehr solution?
Add all panels to the Form at run time (shouldent be a problem since there are only 3-6) Show the current panel while Hide the rest. While having a seperate thread update the 'main' and sleeping panels every say 1/2 second.
Thanks,
Darren

Code is like this:
public void ShowHome()
{
this.Controls.Remove(currentPanel);
currentPanel = new App.Main.MainPanel();
this.Controls.Add(currentPanel);
currentPanel.BringToFront();
}
public void ShowSecond()
{
this.Controls.Remove(currentPanel);
currentPanel = new App.Main.SecondPanel();
this.Controls.Add(currentPanel);
currentPanel.BringToFront();
}
what i was thinking from my previous post was to add all panels at runtime and just .Hide() and .Show() them but have a second thread update them all periodically.

There are 2 ways to do it:
1. Use this.SuspendLayout() before your code and this.ResumeLayout(false) after your code.
2. Use Visible = true or false to Show or Hide panels.

Yeah i tried using .Hide() .Show() (not sure if that works the same as Visible and sets the same flag) but trouble is the panels generate content on specific things so if something has changed and i switch to the new panel the panel hasn't updated if you see what i mean.
Any ideas?

Ok i tried quite a few things but i think i have a new solution:
Im going to create a TemplatePanel Abstract class that derives the Panel class and contains a Update() method, of which any app panels must derive.
Then i will run a thread that periodically calls the Update() method for all panels if the application is not minimised.
If anyone has another solution then please let me know,
Thanks

How We can get information about the nodes attached on LAN programatically ven v r on server?Is there any method already present in C#?
thanks in advance

The ARP table might only hold ip addresses of computers it had reason to communicate with though, not sure on that.

Hi
I am writing a windows application using C# for performing a task as scheduled. Now I am calling a method which does the needful inside the form1 constructor
which is inside the main method like this:
static void Main()
{
System.Windows.Forms.Application.Run(new Form1());
System.Windows.Forms.Application.Exit();
}
now what is happenning is that the control does not reach this statement
System.Windows.Forms.Application.Exit();
and I need to manually close the form which is not what I want.
I want the application (and the form) to close by itself.
How can i do this.
Thanks in advance,
Aryan.

Set timers to enabled true
private void timer1_Tick(object sender, System.EventArgs e)<br />
{<br />
Application.Exit();<br />
}

System.Windows.Forms.Application.Exit(); does not get executed because your program is running an open window on a thread. It will never reach System.Windows.Forms.Application.Exit(); because when you close the window Dispose would have been called already.
Can i ask why you are using a window? If it is to run a scheduled task why not just create a Console Application, this will exit once it has finished executing. If you have the window so you can enter data about what it is you want to run, why not just add switches to execution of your console application like Start -> Run 'myapp.exe "path to filename" "time to start"'

hi all,
I have a class which has a functions to generate XML files based on given parameters, Move these files from one machine to another and execute these files over a database.
Iam able to call these functions fine on a button click event.
It is required that the functions all be automated ..
I tried this by calling these functions from a windows service(C#) in the OnStart() method but i see that they are not executing...
I am not able to debug the windows service.
How can i automate the execution of my class functions using windows service or some other kind of scheduler?
Thanks in anticipation

so far in my knowledge Gridlines can only appear in Details view when set to true. if anybody else have any knowledge about removing horizontal or vertical line i'm interesting to know it too.
regards.

The ListView is one of the most limited controls in .NET when it comes to customising apperance and manipulating sub items. I have tried to use one in an application and get it to do what i want for a week now and read much on it, but never came across showing only vertical or horizontal lines.
I think the only way to do this would be to extend the ListView class and overwrite all Painting methods with your own

Dear gurus,
my app has a rich user-interface which I have to test extensively by mouse-clicking on all the menus, buttons,.....
My idea now is to create a small tool which sends all this clicks,... automatically to my application for testing the user-interface.
Does anyone have an idea how this can be accomplished?
My best whishes and thankyou for your help ! ! ! !

I have a image file in folder i take it and store it in database as a Image Format. after stored in database how can i delete that image file from folder?

You can write a batch file to delete the image from the folder and call the batch file using System.Diagonastics.Process.Start();
E.g
In batch file:
Del <file path="">
exit
After saving in database:
System.Diagonastics.Process.Start("C:\<batchfilename>.bat");
Hope this helps.....
Thanks
