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

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 ?
|
|
|
|
|
Checkout Cinchoo NACHA classes. Hope the library help you on this. Otherwise you will need write your own.

hi,
i already read many articles about it but i dont get it:
i have a datagrid with two datatables. the 2. table has a foreign key colum (to the primary key colum of table 1). so i created and added the datarelation to the dataset.
what i want is that a datagrid shows the 1. table while the listbox shows the elements of the 2. table, where foreignkey = primary key of the selected datarow in the datagrid.
but the listbox only keeps showing all elements of table 2; when only showing data from one table the components keep in sync
so what else is needed for this task, or should i better fill the listbox manually?
thanks for ur answers

Please tell what is difference b/w Node index and Node count?
Please tell how can I make use of Right Mouse Button to select node in treeView. I want to work with context menu in treeView. Please elaborate this.
Thank you.
|
|
|
|
|
Hi
First,Nodes count gets the number of nodes that a treeview or a node contains.Node index is the index of a node within a collection (first node ,second node and so on)
Second you can use the GetNodeAt method of a treeview to get the hitting node(It accepts a point or x and y )

I have an app that's trying to send email via Simple MAPI. When the default client is Oulook, the New Message window that comes up appears to lose focus. I am able to tab thru the varous controls on the message window, but I cannot set the focus to anything inside the window (New Message) with the mouse. Clicking on a different app and then coming back to the New Message window "fixes" the problem.
I'm passing 0 for the parent window handle. I've tried passing in the handle of the main application window, but it did not make a difference. Any help would be greatly appreciated.
Here is what my two MAPI calls look like:
error = MAPILogon(IntPtr.Zero, null, null,
MapiNewSession | MapiLogonUi, 0, ref session);
error = MAPISendMail(session, IntPtr.Zero, mapiMessage,
MapiDialog | MapiLogonUi, 0);

Hi, I am creating a database, and on the first form I want a listbox displaying the names of all the tables, so when a user clicks on one and clicks the OK button, it will open another form showing the data in that table.
What I need to know is how to get the names of the tables in the database without hard coding it.
Thanks in advance,
Any reply is appreciated.

Hi,
have a look at the GetSchema[^] on your connection class. I think it doesn't work on every database and it's also not very comfortable to get the results out of the returned DataTable but it worked for me when wokring with Access databases.

Well, it would help if you mentioned which database you are working with. I can help you with oracle:
for all tables:
'select table_name from dba_tables;'
for tables for a specific owner:
'select table_name from dba_tables
where owner = 'XYZ';'
for all the tables you have access to:
'select table_name from all_tables';
based on the result you may fill the listbox !
hope this helps

How do I programmatically minimize a Form? (I also want to restore the size programmatically).
I'm using VS2003 .NET 1.1.
|
|
|
|
|
Use the WindowState property of your form. The size can be adjusted using the Size property, surprisingly...
