Add the following code to your form. It filters the session end message and sets a flag that can be tested in the Closing event handler.
protected override void WndProc(ref Message m)
{
if (m.Msg == 0x0011)
this.allowClosing = true;
base.WndProc(ref m);
}

Hello stefan,
i have found very simple solutuion to this problem.
before your posting
but than also thanks.
whenever we click on shutdown it will call form closing event in the application
and i have written following code in my form closing event.
this.WindowState = FormWindowState.Minimized;
this.Opacity = 1;
this.ShowInTaskbar = false;
if (this.FrmCloseFlg == false)
{
e.Cancel = true;
}
thats y my application is not going to exit instead it will be in minimize
position.
so i have used one boolean variable and use condition as follows
if(!InSystemTray)
{
this.WindowState = FormWindowState.Minimized;
this.Opacity = 1;
this.ShowInTaskbar = false;
if (this.FrmCloseFlg == false)
{
e.Cancel = true;
}
//UserCanceled = true;
UserInfo.InSystemTray = true;
}
else
{
Application.Exit();
}
The InSystemTray will set to false again whenever we manually clik on open context menu or double click tray icon ,whatever it is.
is it simple na!!!!!
So we dont have a right to call any person an idiot ok buddy,be cool

Hey,
try this:
private void textBox1_KeyDown(object sender, KeyEventArgs e)<br />
{<br />
<pre> if (e.KeyData == ((Keys.Control) | (Keys.A)))<br />
MessageBox.Show("Gotchya!");</pre><br />
}
I'm using the KeyDown event.
Hope that helps,
Ashish

It didn't work cz there is nothing called e.KeyData and if i use e.KeyChar it gives me an error cz i can't compare an object of type char to an object of type key.
if you have any other solution please tell me. thanks.

You said 'Try not to be stupid in you answers' to someone. My response would be, try not to be stupid.
You're obvioulsy overriding the KeyChar event, when you were just told to override the KeyDown event.
I'm not sure if the code you were given will work, but this will:
if (ea.Control && ea.KeyCode == Keys.A)
in the KEYDOWN event, NOT the KeyChar event.

You have to register to either KeyDown or KeyUp event.

If you want to use the Keys enumeration you must use the KeyCode Property of the KeyEventArgs.
The Object Browser documentation for the property is as follows:
public System.Windows.Forms.Keys KeyCode [get]
<br />
protected override void OnKeyUp(KeyEventArgs e)<br />
{<br />
if(e.Control&&e.KeyCode==Keys.A)<br />
MessageBox.Show("Hello World");<br />
base.OnKeyDown (e);<br />
}<br />
In order to use this code you must first enable KeyPreview in the Form's property window. This code uses the e.Control property in the KeyEventArgs and the e.KeyCode property to determine the two keys that were pressed. You cannot get two keys out of the e.KeyCode method (at least that is what I am thinking right now).

Hi all,
i have created a application, which has a notify icon in the system tray.
I have also created a installer for this app.
Now when i install and execute the application, the icon is displayed in the system tray.
Now i keep the app running and UnInstall the app from the Add/Remove Programs.
The uninstall process displays a message to close the form. i close the form and continue the uninstall process.
The application is successfully uninstalled, but the icon from the system tray does not goes , and also the exe exists in the task manager.
Now if i click on the icon the form is displayed and the app runs perfectly,
even the app is uninstalled.
My question is how do i remove the exe from the taskmanager and also the icon from the system tray during the uninstall process.
I tried a solution, by creating a small console app which searches the app's exe from the process and kills the process.
I added this project in the Custom Actions Uninstall folder, but this is not working.
Any help in this regard will be appreciated.
Thanks & Regards,
Pramod

So i want to disable the scrolls so the windows inside can not go father that the dimensions set. Somebody told me to try to set the dock property but a container does not have that property.

you can set scrollbar property through properties of container where you can disable scroll bars.
|
|
|
|
|
The problem is that i dont find a property that can disable the the scroll bars. i was looking thoughout all the properties. but you can tell me a little more.
Thank you,

There are a variety of ways. The rolls royce solution is to by the .NET builder (~$10k). This allows you to wrap your matlab code into a dll and call it natively in C#. Its a excellent product and I recommend it, if one has the money.
You can also call matlab thru COM, or you can write MEX files. Both of these alternatives are discussed in the help and user forums on the matlab site: www.mathworks.com. We've used both of these and while laboreous they do work.
Hope this helps.

I'm looking for classes/code that can produce ACH or NACHA transactions.
Ideally I would send the transaction details to the class, the class would produce the NACHA format transaction and then return the formatted transaction to me
Does anyone know if something like that exists ?
