Well, as I said before I should be able to get the name of the window with the Form1.Name field. What I wanted to do is trying to get the classname for my window.
Because it is something like WindowsForms10.Window.8.app88 and that's what I do not want to hardcode because this changes everytime I reboot my PC. It could be WindowsForms10.Window.8.appdd as well.
With "second instance" I ment the user shouldn't be able to invoke the same application on the same PC twice, e.g. by clicking twice on the button. If he does the running application should reappear.
So because it's the same application (but just a second instance) the classname has to be the same. So the second invokation would have the same classname (prooved via Spy++) so I should be able to get the classname from somewhere. But I am not sure where to fetch it.
I also have a mutex on the instance, maybe I could fetch the Handle from there if it is possible to use it in this context.
Stephan.

what about if you just do the following:
add the handle hash in the registry and evey other application will be able to check it. And if it matches then the application is running. Or if the value is set, then the application is running.
But do not forget to reset the value, because otherwise you won't know if there is an application running or not!

Your problem is very vague, have you looked through the code that you downloaded, what is it doing? Have you contacted the author of the code/article, what did he/she say? If you have a specific C# question many on here would be glad to help you.

hi,
Actually i posted one queary that " How we will change the color(caption color) of a Tabpage". Unfortunately i forgot to post the answer here. So Here is the answer for " How we will change the color(caption color) of a Tabpage.
Who is going to draw ?
Tabcontrol have a properties called DrawMode. This will set or get the value that whether user or system will paint the caption.By default it is normal. Means system(OS) will paint the caption for you. If you(parent form) want to draw the caption you have to set the value of the property to OwnerDrawFixed.
You can mention DrawMode on design time or runtime like below mentioned code.
this.tabControl1.DrawMode = System.Windows.Forms.TabDrawMode.OwnerDrawFixed;
Now you mention who is going to draw the caption.
Next thing is how is going draw ?
Tab control have an event called DrawItem event which will occure when ever an area need to be painted.
eg:
this.tabControl1.DrawItem += new DrawItemEventHandler(this.tabControl1_DrawItem);
private void tabControl1_DrawItem(object sender, System.Windows.Forms.DrawItemEventArgs e)
{
Font f;
Brush backBrush;
Brush foreBrush;
if(e.Index == this.tabControl1.SelectedIndex)
{
f = new Font(e.Font, FontStyle.Bold | FontStyle.Bold);
backBrush = new System.Drawing.Drawing2D.LinearGradientBrush(e.Bounds, Color.Blue, Color.Gold, System.Drawing.Drawing2D.LinearGradientMode.Vertical);
foreBrush = Brushes.White;
}
else
{
f = e.Font;
backBrush = new SolidBrush(e.BackColor);
foreBrush = new SolidBrush(e.ForeColor);
}
string tabName = this.tabControl1.TabPages[e.Index].Text;
StringFormat sf = new StringFormat();
sf.Alignment = StringAlignment.Center;
e.Graphics.FillRectangle(backBrush, e.Bounds);
Rectangle r = e.Bounds;
r = new Rectangle(r.X, r.Y + 3, r.Width, r.Height - 3);
e.Graphics.DrawString(tabName, f, foreBrush, r, sf);
sf.Dispose();
if(e.Index == this.tabControl1.SelectedIndex)
{
f.Dispose();
backBrush.Dispose();
}
else
{
backBrush.Dispose();
foreBrush.Dispose();
}
}
}
Sory for this late posting

Due to the large number of posts within the C# forum I would suggest that you consider writing up your findings in an article and posting it, otherwise this post will get lost and won't provide much help for others in the future.

how to change the Height of the Title Bar for a particular application irrespective of what the user sets the height in Display properties and in Xp and Classic Styles?(in SDK, C#)

Hello,
I have a cute little problem here. I want to enable the logging for login events from within my program, but I cannot find anything about that. In windows you can set it from Local Security Settings -> Local Policies -> Audit Policy.
Does anyone know how to do this? I'm really Stuck here.
|
|
|
|

Those policies map to reigstry entries. I recommend you search http://msdn.microsoft.com/library[^] or http://support.microsoft.com[^] to find which registry entry that GPO entry maps to. Then changing is easy: use the Microsoft.Win32.Registry and Microsoft.Win32.RegistryKey classes, which are documented in the .NET Framework SDK and simple enough to use.
EDIT: You could also open the policy template (don't remember where it is off-hand, but that is in the MSDN and Support sites, too) and see where it is. The policy templates are pretty simple text files that you could even open in Notepad and search for to find the friendly name (i.e., what you see) and then find what registry key it maps to.

Damn,
I wish it was that easy, but I've tried everything, and I cannot find the key.
Anyone got more ideas?
|
|

Sorry to say, but that works. All the policies do is set registry keys - nothing more. With some settings, a reboot may be required, though in Windows NT the policy update cycle (default is 15 minutes) is usually sufficient.

Okay, I found it,
the thing was that the registry key was secured, so I couldn't see it myself. Adjusting permissions edited the whole issue. Just one problem, I need to read the Default Value of the key HKEY_LOCAL_MACHINE\SECURITY\Policy\PolAdtEv, but how the hey can I do that, If I want to read a keyValue, I must supply a keyname, but the defaultvalue hasn't got any :S.
thanks for your help so far, I wouldn't have gotten this far without it.

|

Okey, I found how to read the default value. But now I've got a whole different problem. Since th type of value is REG_NONE I cannot get the value out. even though I know it is Binary.
Does anybody know how to read this kind of values anyhow? Or another workaround?

Help me, please ! How can I get a content of RichTextBox as Image (or Bitmap, or Metafile) or save it to a graphic file (any format) ?
|
|
|
|
|
Read How To Print the Content of a RichTextBox Control By Using Visual C# .NET[^] and modify the Print method documented in the KB article so that it accepts a Graphics object as the last parameter instead of a PrintPageEventArgs (you'll need to pass a struct for margins as well). This will allow you to pass a Graphics object (ultimately, the HDC - or handle to a device context - is used) for printing or to save an image.

HI~
I am using compact framework and
I have written a class which extend Microsoft.WindowsCE.Forms.MessageWindow
How do I register the window class in C# so that I can find the window by using the function "FindWindow" ??
Note that the handle of the message window is existed in the instance of the MessageWindow.
|
|
|
|
|
FindWindow is a native function, however if you look at the documentation for FindWindow[^] on MSDN you will see that if you pass null for the lpClassName parameter it will find any window whose title matches the lpWindowName paramter. The P/Invoke signature for FindWindow is as follows:
[DllImport("user32.dll")]
static extern IntPtr FindWindow(string lpClassName, string lpWindowName);
This works if you pass null as the first parameter, however if you want to specify the class name, you will have to override the CreateParams and specify the ClassName property.

Yes.
However, the message window has no window title
So I cannot use the second parameters.
I would like to get the handle of a window which has no window title as the window is not a form and also the window is a class of of C#. Also I use compact framework so there is no System.Window.Forms.CreateParams. So...
How do I get the handle of the window?
Thanks

Hy everyone!
Could anyone of you tell me how to implement checking if the minimizebutton on my WindowsForm was clicked?
I had a solution which worked but well when I switched over to another application to drag&drop some data the application was minimized as well and no longer shown in the taskbar.
But what I want to do is:
When switched to another application to drag&drop data the application only moves to the background but is still be shown in the taskbar. If the minimizebutton was clicked then my application should minimize and not be shown in the taskbar (except the icon to resize my application once again).
Thanks!
Stephan.

hi,
Minimizing a form to an icon at run time generates a Resize event. The WindowState property reflects the current state of the window. If you set the WindowState property to 1 (Minimized), the Form is minimized independently of whatever settings are in effect for the MinButton and BorderStyle properties.
private void Form1_Resize(object sender, System.EventArgs e)
{
if(WindowState == FormWindowState.Minimized) >> check this
}

hello all,
Is there anyway to decompile a framework function so that I can see exactly what it does? The reason I want to do this is that I am having a few issues with :
HttpServerUtility.MapPath(string)
The issues I am having are far to long and complicated to get into, but any help would be greatly appreciated.
Another option would be to somehow debug the method so I can see what data is actually travelling through it.
post.mode = postmodes.signature;
SELECT everything FROM everywhere WHERE something = something_else;
