Hy everyone!
When I do clone menues do I clone them as a whole meaning, the Menu, the Items and the actions which they did or do I only clone the items?
Because what I want to do is cloning an existing menu and adding some new items to the cloned menu. But I am not sure if cloning only creates a copy of the menu without the actions or with them.
I only found examples describing cloning the items but there were no infos available if the actions were also cloned.
Thanks!
Stephan.

hi,
i can give a small hit. If you took the methods
MergeMenu() -> This will merges another menu's items with this one's as specified by these mergeType and mergeorder properties. This method is used to merge an MDI continer's menu with that of its active child.
CloneMenu() -> This will create a deep copy of another menu.

hi,
I faced same problem in my application. So i can tell you what you can do. See i tried a lot to achive this.But upto my level beast no point. It may possible for some gurus in codeproject but i am not sure.
In my application i wrote custom class to fix my resolution to 1024*768. I completed my application. Then i submitted this as a article in codeproject.com . But i didn't got excellent feedback. I got only above average feedback. So if you want then you can refer my article called "Dynamic Resolution Fixer".
this is that cool link.
http://www.codeproject.com/csharp/CSDynamicScrRes.asp
If you want to know more about the working style.Then you can contact through codeproject.com.

thnx for reply.
i hve study ur article it tells u how u can forcefully retain a specific resulation but i dont want this.
acctually i want to allow user to change his resulation, and according to this i hve to adjust my controls.
so my question is still there
1- on changing monitor resulation which event of form fires?(its not Resize).
2- the shortest way to tackle this problem.
Regards,
farukh ali farooq

For some reason, left, right, up, and down arrows aren't getting caught by OnKeyDown. Does anyone know what could be causing this problem?

The OnKeyDown and OnKeyUp events don't catch the arrow keys. OnKeyPress catches the arrow keys.
It's an annnoying little workaround, the OnKeyDown/OnKeyUp catch the ASCII chars and the modifiers (Ctrl, Shift, Alt) but not the arrow keys and the OnKeyPress catches ASCII chars and arrows but not modifiers.

how to create a menu that has a vertical text in the left side ?
thanks...

With the software I am writing, user input is coming in via custom controls ( physical ones ) plugged into the serial or parallel ports. Does anyone have any experience in watching those ports in C# ?
Thanks

You can't get to the ports directly uising C# alone. You need a .DLL file running in Ring 0 to do the port work for you and expose an interface that you can use in C#. Check out http://www.logix4u.net/[^].

I'm working on a UserControl which allows other controls to be drawn onto it (Much like a Panel or GroupBox control).
However, now I want to define the area in which controls can be placed and drawn (Called the client area, I think) - the TabControl control is a good example of this, controls can only be placed in the rectangle shown with the dashed line. How can I define this area in my own User Control?
Thanks

Sorry to bump this n'all... but seriously, no-one's done this before?

In theory, you might want to experiment with a Panel control to handle that for you. You'll probably have to handle the drag and drop for your control's client area and what your calling your client area (the Panel control) to make sure that objects of type System.Control get dropped on your area instead of anywhere in your control.
And no, I haven't done it before...

how do you check if an input string is numeric?
|
|
|
|
|
C# doesn't really have an IsNumeric function like VB had. Even though it's not the best idea to intentionally use the try/catch block for functional code, what I sent you yesterday will work.
try
{
O = UInt32.Parse( string_expression );
}
catch
{
}
if the string_expression is not in the correct format for a UInt32, it will throw an exception, which you can handle in the catch block. There are quite a few forum discussions on this, with some examples on how to implement a better IsNumeric function without using the try/catch block.

You can use Char.IsNumber to walk over the string looking for any bad input, you can use a textbox derived class that only accepts numbers, or you can use regular expressions. If
Regex.Replace(inputString, @"[-?][\d*][.?][\d?]", "").Length > 0
then you don't have a number. That's not tested, but it's close. It's looking for an optional -, digits, an optional . and optionally, more digits.

private bool IsNumeric(object value)
{
try
{
double d = System.Double.Parse(value.ToString(), System.Globalization.NumberStyles.Any);
return true;
}
catch
{
return false;
}
}
if (IsNumeric(text1.Text)
string tempvalue = "This is a NUMERIC";
else
string tempvalue = "This is not a NUMERIC";
