hi,
i have a Mesh that fills all the screen and i want to get a window loaded in the app so i can interact with it as realy active window
can i make my app form is parent for this certain window if yes how ??

|
|
Uhhhh....What?
I can't make any sense of what your trying to do. What are you trying to interact with and how do you want to interact with it?

i want to interact with real windows but in my app (the window must be in my app form(like parent))

I take it you want to edit something in a child window of your Multiple Document Interface (MDI) app? And on top of that, it's a DirectX app?
If that's the case, specifically what's the problem your having?

yes this the problem but the windows is an operating system window("c:","IE")for example
|
|
|
|
|
What????????????????
Mesh??? Another app's windows??? DirectX???
I hate to say this, but, none of this is making any sense...
You want to work in another app like that app's window was in your application? Are you asking how your application can control another application?

yes how can i control another app from my DirectX App??

Finally! OK. What you ask is not that easy and is problematic at best.
You can look into using SendKeys to stuff keystrokes into the message stream of the app you want. But since the focus can bechanged between the time you activate the app you need to send keystrokes to, or even during sending the keystrokes, the focus can change to another app.
Doing stuff with the applications windows will require you to look into the Win32 API and creating the structures and function declarations for C#. This includes something as simple as moving a window or maximizing or minimizing it. You'll have to use functions like GetWindow, GetWindowPlacement, SetWindowPlacement, SetForegroundWindow, SwitchToThisWindow, MoveWindow, ... plus all the structures that these functions use!
You might want to consider writing the bulk of this code in C++ instead of C# because all of the functions and structures already come in the header files and libraries natively used by C++ to write Windows apps.
Have fun and stock up on some Advil or Excedrin. You'll need it!

The follow will work:
using System.Diagnostics;
Process[] pa = Process.GetProcessesByName("WINWORD");
if(pa != null)
{
int count = pa.Length;
}

I would just use the tools available in System.Diagnostics.
Example:
System.Diagnostics.Process[] runningProcess = System.Diagnostics.Process.GetProcessesByName("WinWord");<br />
<br />
foreach(System.Diagnostics.Process proc in runningProcess)<br />
Console.WriteLine(proc.Id);
The most exciting phrase to hear in science, the one that heralds the most discoveries, is not 'Eureka!' ('I found it!') but 'That's funny...’

Thank all of you. This is very helpful!
Here is what I did using Win32API(I import the user32.dll and put it into my Win32API class), but it doesn't work as I except.
public int CheckWord<br />
{<br />
int num;<br />
string lpText = new string((char) 0, 100);<br />
IntPtr hWnd = Win32API.GetWindow(Win32API.GetDesktopWindow(), Win32API.GW_CHILD);<br />
<br />
int UStnNumber = 0;<br />
while ( !hWnd.Equals(IntPtr.Zero) ) <br />
{<br />
num = Win32API.RealGetWindowClass(hWnd, lpText, lpText.Length);<br />
if ( num > 0 ) <br />
{<br />
if ( lpText.Equals("OpusApp") ) <br />
{<br />
UStnNumber ++;<br />
}<br />
}<br />
hWnd = Win32API.GetWindow( hWnd, Win32API.GW_HWNDNEXT );<br />
}<br />
return UStnNumber;<br />
}
Do you know why?

Yes, I did. It works very well. But I just wonder why my way doesn't work.

I'd like to create a ToolTip in my TreeView that acts just like the ToolTip in Visual Studio Text/Code Editor:
1. Show tooltips for each Node in the TreeView without having to move the mouse out of the TreeView and back in.
2 Show the tool tip until the mouse moves again...
Any ideas ?

The ToolTip component in the .NET base class can be used if used correctly. Try the following search[^] and find the articles by Nish and ramshri. They suggest one way of doing it.
Since the tool tip control is really just a popup window, you could always create a popup window with no border and perform a lot of the functionality yourself, like resizing it appropriately, etc. For an excellent article that takes this approach for a Balloon Window.

Hi,
I know that it is possible to view checkboxes at each treenode, but it is possible to hint some of them? For instance my Root-Node should doesn't contain one, but all others.
Any solutions?

Not with the TreeView in .NET. The Tree-View common control - which is encapsulated by the TreeView control in .NET - doesn't support this either. There are many third-party controls out there like UltraWinTree from http://www.infragistics.com[^], and one from http://www.devexpress.com[^], though I haven't had a chance to use that one yet. We do use the Infragistics control in our application for this and many other reasons because it was far cheaper to use a third-party control rather than spend the time overriding behavior of the existing TreeView or making our own from scratch.

Actually, I just remember something that worked for a ListView (encapsulates the List-View common control) and that there was something similar in the Tree-View. It isn't easy, though, and you should have some experience with Win32 programming.
Using image lists, there is a way to hide a check box for a tree node, though it can be a bit tricky. See the documentation for the TVS_CHECKBOXES style in the Tree-View Windows Styles[^] reference on MSDN Online in the Platform SDK. It provides some basic intructions along with links to more resources. This is more of a trick with an Image List rather than the Tree-View itself.

Hi,
it is possible to defined a separated contextmenu for some TreeNodes? Or it is possible to enable a contextmenu for some nodes and for other nodes not? I hope I can do that, how?
Thanks for reply.

One easy way would be to have a ContextMenu assigned to TreeView.ContextMenu (inherited from Control). Handle the Popup event and customize your MenuItems in the handler. Another way - although consuming more memory - would be to have separate ContextMenu instances and not assign anything to TreeView.ContextMenu. Handle the TreeView.MouseDown or TreeView.MouseUp events (whichever you prefer) and call ContextMenu.Show, passing the TreeView as the first parameter and the X and Y coordinates in a Point (from the MouseEventArgs) as the second parameter to Show. This calls the TrackPopupMenu native function internally.
