Hi,
I'm not sure what your question is.
If you are creating a program (in C# as implied by this forum) then you
want to use the ContextMenu.Popup event to clear, then populate your
context menu with items that depend on the item for which context is requested.
Code would include things such as:
contextMenu.Popup+=new System.EventHandler(myPopup);
private void myPopup(object sender, EventArgs e) {
Menu menu=sender as Menu;
menu.MenuItems.Clear();
mi=addMenuItem(menu, "Copy File", new EventHandler(CopyFileHandler));
mi.Enabled=LongNameIsFileSpec;
mi=addMenuItem(menu, "Explore", new EventHandler(ExploreHandler));
mi.Enabled=LongNameIsFileSpec;
...
}
protected MenuItem addMenuItem(Menu menu, string text, EventHandler handler) {
return addMenuItem(menu, text, Shortcut.None, handler);
}
protected MenuItem addMenuItem(Menu menu, string text, Shortcut sc,
EventHandler handler) {
MenuItem menuItem=new MenuItem(text);
menuItem.Click+=handler;
menuItem.Shortcut=sc;
menu.MenuItems.Add(menuItem);
menuItem.Enabled=handler!=null;
return menuItem;
}
If you are referring to the context menu presented by Windows Explorer,
there are basically two ways to add user defined menu items:
- you can add an item for all files, all folders, or all files+folders by
creating the right entries in the System's Registry
- you can have Explorer start a small user-provided program to dynamically
add one or more context menu items very time something gets right clicked.
Hope this helps.

You need to use Shell-extensions for that. Try a search on the interfaces IContextMenu, IContextMenu2 and IContextMenu3.

Hi,
this is how I do it:
- I have my program contain a menu item to install itself as a possible
tool to open all files and folders
- when that menu item is clicked, it creates two registry entries:
HKEY_CLASSES_ROOT\AllFilesystemObjects\Shell\myProgName.ContextMenu
(Default)=text to show in context menu
HKEY_CLASSES_ROOT\AllFilesystemObjects\Shell\myProgName.ContextMenu\Command
(Default)=myProgPath %1
myProgPath can be obtained as Environment.GetCommandLineArgs()[0]
%1 means append the file/folder selected, and will result in a command line arg
For manipulating the registry, I use P/Invoke to OpenKey, CloseKey, and
RegSetValueEx since I want my code to also work under .NET 1.x;
but starting with 2.0 there are easier ways to do it.
BTW the (Default) key is accessed with name=null.

Hey all
Im trying to test for every possibility of a string for a user defined length
right now i have an string array with a-z0-9
and i iterate through it with an for loop
my problem is how to get it to roll over with out just making it a series of nested for loops so the user can define the length and say output me every possibility for 8-10 or 1-9
I know it would be rather large output files but thats not really a big concirne at the moment
Thanks

What is "every possibility"? Do you mean permutation[^]?

Is permutation still what im looking for?

I have a custom control that is just a ImageButton. How do I make a property that I can pass an event to it. Just like I can do with a normal ASP Button, OnClick="MethodToCall".
Thanks for all the help, or leads in a direction!

21:?
================================================================
here are 20 groups of data ,and they are selected at random from 000 to 999
based on these numbers ,can you figure out the inner relationship among these datas,and try to predict the 21th group of data?

|

I tried. But its difficult to predict. Do you know how to predict?

I try to predict the 21th group of data is 410

What do you want to achieve? Is this homework? I guess it is not very difficult to find out if you know what random means.

I'm trying to get server's responce (status) code and use this code:
int statusCode;
try
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Method = WebRequestMethods.Http.Head;
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
statusCode = (int)response.StatusCode;
response.Close();
}
catch (WebException ex)
{
if (ex.Response == null)
throw;
statusCode = (int)((HttpWebResponse)ex.Response).StatusCode;
}
But when I use this code, the time of getting the result is from 300 ms to 5 s. I think this time can be cutted. Help me, please.

Hi!
I'm new in this forum, and I know about C# language but don't know about architecture.
I've been coding monolitic (1 tier) applications, but I'd like to learn to code (C#) applications with some tiers.
I was reading about tiers and levels but I don't know how I should to code each tier. Is each tier a class library or simply a class in a project?
Can sombody tell me where I should to read in order to learn about architecture coded with C#?
Thank you in advance.

In hardcore tiered app each tier is on its own server Ideally each tier should know only necessary minimum (e.g UI tier shouldnt know about data storage), so divide them as much as possible - I vote for different class libraries.
FYI, there is Design and Architecture[^] forum...

I made a custom control, I have a property called Text. When I try to use the control on a page the Text property is set AFTER the control has finished doing the code that needs to use the Text property.
How do I get the Text property to set the instance field prior to running most of the code? Is it an event?

I think, the better idea is ask here. Reasons:
- you don't waste anyone time;
- you can get answer very quickly;
- you can get many different ideas, from different people, how to do something, and choose the one you like or fit the best;
etc.

thanks. i want help with creating my own context-menu
|
|
|
|

ok, so you drag a toolbar (aka toolstrip in vs2005), menubar (aka menustrip in vs2005), contextmenu (aka contextmenustrip in vs2005), explorer bar...which i guess you mean a status bar, dockable is just a propery.
if you don't know VC# then learn it, don't ask other people to program for you.
