You can create a new class A inheriting from Panel adding the next lines of code. After that all the classes inheriting from A will have again the design view.
<br />
[Designer(typeof(System.Windows.Forms.Design.DocumentDesigner),typeof(System.ComponentModel.Design.IRootDesigner))]<br />
public class A : System.Windows.Forms.Panel<br />
{<br />
....<br />
}<br />
...<br />
public yourpanel : A<br />
{<br />
....<br />
}<br />

Thanks to all responses to my questions!
Jose Fco Bonnin gave me just what I needed! After making my own custom panel type I inherited from that to create a panel I'm going to use in a winform app and it did show the design view again, great!

Thank u
I did it my self
and here is the code

{
if(this.lb_target.SelectedIndex != -1)
{
if (this.lb_target.SelectedIndex != 0)
{
object tempob=this.lb_target.SelectedItem;
int index=this.lb_target.SelectedIndex;
this.lb_target.Items.Remove(this.lb_target.SelectedItem);
this.lb_target.Items.Insert(index-1,tempob);
this.lb_target.SelectedIndex=index-1;
}
}
}
private void btn_down_Click(object sender, System.EventArgs e)
{
if(this.lb_target.SelectedIndex < this.lb_target.Items.Count-1)
{
object tempob=this.lb_target.SelectedItem;
int index=this.lb_target.SelectedIndex;
this.lb_target.Items.Remove(this.lb_target.SelectedItem);
this.lb_target.Items.Insert(index+1,tempob);
this.lb_target.SelectedIndex=index+1;
}
}

You have to have DirextX9.0 SDK. And when you install it there are some samples with it which you canfind your answer there.

or just use CsGL(OpenGL Port to C#)

Dear, Sir
I launch Calculator by the following code
System.Diagnostics.Process.Start("calc.exe");
How to active the Calculator I have launch again when I press a button on my App.
Thank You.
Sorry for bad English.
|
|
|
|

I think what you want is to activate the calculator app. you have already launched through code, without launching another instance of it.
For this you need to use FindWindow api to determine whether you have the application(calc) active and then activate it by SetFocus API.
You need to pass the handle returned by FindWindow function to the SetFocus API. You need to P/Invoke for calling these two API's.
Cheers,
Kannan

I'm really frustrated with this. The images looks fine under edit mode, but they all disappeared when the application is running. What happened?
I know there is a solution about adding "Application.DoEvents()" after "Application.EnableVisualStyles()", but it doesn't work for me...
Anyone has an explanation? Thanks!

Does it work if you dont call Application.EnableVisualStyles()?
I have stopped using that, and just put a manifest file together with my app, much less problems...

I have tried all, with or without EnableVisualStyles(), with or without manifest file. Nothing works.
It actually worked for me for a while, but at some point during coding(probably after I changed the font to some labels on the toolbar), it disappeared and would never get back.

After a research using Diff tools, I found the problem was the font of the tool bar. It worked fine under default font, but if I change it to any other font, even after I changed it back to the original default font, the images on toolbar will disappear!!!
I don't know why, it's probably a bug of Microsoft.
I wrote a small Windows Form app, it works fine. It's only in my application that the font change will affect the toolbar images.
Thanks,
Jason

Hi,
In VC++ 6, I can put "\t" in the text of a static control and it will show as a tab. But in VC# .Net, it doesn't work for me? How can I insert a tab?
Thanks!

Assigning a string to Label.Text (which inherits form Control.Text) internally calls the SetWindowText native function (most controls encapsulate common controls and Windows Management APIs). SetWindowText does not expand tab characters.
To get this effect, you might consider extending Label and overriding the OnPaint protected method (when extending, override the methods that raise the corresponding events instead of handling the events - it's faster and gives you more control (like deciding whether or not to call base.OnEventName)).

I have a form where I have assigned the left and right cursor keys to perform functions, using the following code:
private void SAPtastic_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e)
{
e.Handled = true;
switch(e.KeyCode)
{
case Keys.D1: movecopysap("1"); break;
case Keys.D2: movecopysap("2"); break;
case Keys.D3: movecopysap("3"); break;
case Keys.D4: movecopysap("4"); break;
case Keys.D5: movecopysap("5"); break;
case Keys.D7: movecopysap("Unclassified"); break;
case Keys.NumPad1: movecopysap("1"); break;
case Keys.NumPad2: movecopysap("2"); break;
case Keys.NumPad3: movecopysap("3"); break;
case Keys.NumPad4: movecopysap("4"); break;
case Keys.NumPad5: movecopysap("5"); break;
case Keys.NumPad7: movecopysap("Unclassified"); break;
case Keys.Space: movecopysap("Unclassified"); break;
case Keys.Back: if (apnt > 0) {apnt = apnt - 1; LoadnScale();} break;
case Keys.Left: if (apnt > 0) {apnt = apnt - 1; LoadnScale();} break;
case Keys.Right: if (apnt < (al.Count-1))
{apnt = apnt + 1; LoadnScale();} break;
case Keys.Home: apnt = 0; LoadnScale(); break;
case Keys.End: apnt = al.Count -1; LoadnScale(); break;
default: e.Handled = true; break;
}
}
The odd thing about this was that whilst I did create an override on IsInputKey to allow me access to the cursor keys, it is never called - if I remove it there is no difference to the operation of the program.
That is not the REALLY WEIRD THING, I added a toolbar at user's request and now the cursor keys need to be pressed twice in order to get them to function. The above code is not called on the first keypress, but is on the second.
I gets worse... I included an option to not display the toolbar, if the toolbar is disabled - the keys work fine!
Any assistance would prevent me having yet another sleepless night and so would be much appreciated!

Is this code in a Form to handle the various inputs? If so, set Form.KeyPreview to true. Since child controls will have the focus, the parent Form will not receive key notification messages unless KeyPreview is true.
I'm not sure why the toolbar would change things, but I'm guess that internally (the native Toolbar common control) is that it routes messages to the parent, perhaps causing other child controls to do it, too. Not sure, though.

Thanks for the reply - I was beginning to wonder if anyone would answer my plea!
That property is already set, I too am unsure why the addition of the toolbar would change things. With this in mind I returned to a previous version of the code before the toolbar was added, the mear addition of the toolbar without adding buttons or changing settings resulted in the same behaviour.
I may have to replace the toolbar with a groupbox and ordinary buttons ;-(

I have been trying to monitor the handshake (signal) from
a printer for each page it printed but i have not been
able to do so. Can any out there help me.

That might be a little too low level for C# to handle easily. In the Windows DDK there are a set of parallel port functions you can try to hook into (like IOCTL_INTERNAL_GET_PARALLEL_PORT_INFO) but I don't think any of them have been exposed in C#. And that assumes that you are using a parallel port printer.
If you are doing lower level OS I/O, C# tends to be a poor choice to use. The abstraction layer PrintDocument is there to avoid the messy OS level details of talking to the hardware. Why are you interested in the hardware communication?

I have written my first .NET app (yes, I'm a .NET newbie) very simple app just testing out some of the form functionality. Everything works well on my machine but when I copy it to our network and execute it from there I get
a System.Security.SecurityException thrown (Additional Information: "Request Failed") when creating the main form, Form1.
I know this is probably something simple but would really appreciate the help. I haven't done anything related to security yet (at least not that I know of!) so I would have thought that security wasn't an issue
Help! I'm going nuts
thanks in advance
CJE

1) Open Control Panel -> Administrative Tools -> Microsoft .NET Framework Configuration.
2) Expand Runtime Security Policy -> Machine -> Code Groups -> All Code.
3) Select Properties from the right-click menu of LocalIntranet_Zone.
4) On the Permission Set tab change the Permission Set to FullTrust.
