I'd create a user control that displays the properties of each aspect of your software. Then, swap in (make visible, set position) the appropruate panel on the right of the list box when the selection changes. You'll need to prevent a selection change if validation of the currently displayed panel fails.

Hi,
the easiest approach for showing a lot of groupable settings, is by using a
Tab Control with several TabPages. The tabs would be organized horizontally then.
If you really want it with the tabs to the left, I suggest you build your own
Tab Control look-alike.

Or you could wire up a ListBox and a TabControl to solve this problem.
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
this.tabControl1.Region = new Region(new RectangleF(this.tabPage1.Left, this.tabPage1.Top, this.tabPage1.Width, this.tabPage1.Height));
}
private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
{
if (((ListBox)sender).SelectedIndex == 0)
tabControl1.SelectTab(0);
else
tabControl1.SelectTab(1);
}
}
I'm using the region setting to hide the TabPage selections from the UI, so the ListBox can be used to control the TabPage display. Obviously, you migth have more than two TabPages, so you'd need to change the listBox1_SelectedIndexChanged() event to control your TabPages as you need.
I hope that helps.

IN VB.NET I use to write :
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click,Button2.Click, Button3.Click
and any code inside
End Sub
I use this way if i want many button to do the same thing
My Question is how i can do like this in C#
it's urgent for me
Thanks in advance

One way would be:
Button1.Click += new System.EventHandler(this.Buttion1_Click);
Button2.Click += new System.EventHandler(this.Buttion1_Click);
Button3.Click += new System.EventHandler(this.Buttion1_Click);
Hope that helps.

Where I should this snipet of code ???
Assaf

|
|
|

Form load would be a good place to put that snipet of code. That way it only runs once. If the code were to run twice you would get multiple calls to your button click event which would be very bad.

I pure GUI way would be to go to your form. Click on Button1 then go to the properties window. Click the lighting bolt this shows you the events for the button. Select the correct button click event. Repeat for other buttons.
Hope that helps.

I didn't get the methode of inserting code

Or you can just double-click the button
|
|
|
|
|
That works for the first event only. If you want to point the other two buttons to the same event you can not double click.
Ben
|
|
|
|
|
No, you click on properties, then the lightning bolt ( to show events ), find the click event, click in the box, click the drop arrow and select the method name.

That is what I said in my earlier post. In my post you are responding to I said you can't double click to assign the same event to multiple buttons.
Ben

I would suggest that you create two simple projects, one in VB and the other in C#. In both applications you would have a form with three buttons. In VB have a method that handles the button clicks for the controls like what you have above. In C# you would assign the method to the click event of each of the three controls. Run the programs to make sure they do what you want. Then examine the IDE generated code, the code that contains all the event/control/layout declarations for VB and VC#. Compare what is similar/different with the two languages.
Hopefully this helps.

I added a lot of ComboBox controls to WinForms form.
Every combobox shows all its content selected.
Selection is removed only when I tab off from the control.
How to hide selection initially?
There is not HideSelection property in Combobox.
This occurs if I set autocomplete properties.
class myComboBox : ComboBox {<br />
internal myComboBox(DataRow dr, DataTable table) {<br />
DisplayMember = "DisplayMember";<br />
ValueMember = "ValueMember";<br />
DataSource = lookup.GetPickList();<br />
DataBindings.Add("SelectedValue", table,<br />
dr["controlsrc"].ToString());<br />
AutoCompleteSource = AutoCompleteSource.ListItems;<br />
AutoCompleteMode = AutoCompleteMode.SuggestAppend;<br />
}}

Have you found a solution to this? I am currently having a similar problem when binding a DataTable to my comboboxes...
|
|
|
|
|
No I havent found any solution to this .net bug.
Maybe it is possible to acces the underlyoing textbox which is contained in Combobox in combo constructor and set it HideSelection property to false.

I'm not sure the exact answer, but anytime you are looking for a Win32 API function, you should check out the site http://www.pinvoke.net/.

Hi,
what changes on the desktop ?
AFAIK:
- the resolution, the pixel depth, ... that will fire a Paint event; see also
the SystemEvents class.
- the icons (new, renamed, moved,...): no event available
- the background image: no event available
Hope this helps

Actually i need to send the image of my desktop to remote computer whenever desktop gets changes. So for this, the i am expecting a common event(for opening new window on the desktop ,selecting the desktop area,minimizing and maximizing any window over the dekstop) that can be caught in my application and at the same time it sends the desktops changed image to the remote computer. So plz any body have any idea?? Actually i know there happens a Paint System event, if so how can i handle this event in my application to know the changed state of my desktop??
Thank you in advance!!

How does one receive events in a C# windows service from a COM object that has been instantiated from a background thread whose ApartmentState == ApartmentState.STA? I’ve been able to received events from the COM object in a WinForm app when the thread sits in a loop sleeping and invoking System.Windows.Forms.Application.DoEvents(), i.e. pumping the message queue.
The thread that accesses the COM object is responsible for responding to requests by other objects to access the COM object, done through a queue + AutoResetEvent, and for handling events raised by the COM object in response to those requests.
Other posts/web sites have mentioned that STA threads require a message loop/pump. It seems like if the thread that accesses the COM object were able to call a method that could sleep + message pump + respond to requests to wake up, I’d be set. Is there such a beast/can such a thing be created? Is this the right kind of design?
Thanks,
Steve

My understanding of windows services is they are not on the windows message queue, so it is doubtful you would ever be able to receive those messages.
