Do you want to know which are open or which are active, because there's a difference? Only one top-level window can be activated on the entire desktop at a time. If you want to get the active form in your application, then use the static Form.ActiveForm property.
If you want to know which windows are open, then you need to track your Form variables.

Hi
Is there a way to find any of the managed directx dlls eg. microsoft.directx.dll if the user doesn't have the directx sdk installed?
Thanks

Basically on computers with directx 9c sdk installed there is a Microsoft.NET/ManagedDirectx directory in the windows directory which contains the directx dlls. Is there any way for users to access these without having the directx sdk installed?
thanks

What to you mean by "access"?
If the files are on disk then yes, this folder has no special permissions on it.
If you need Managed DirectX to be on the system for your application to run then you need to install the DirectX redistributable with your application. The SDK is a Software Development Kit which has additional aids and documentation for developing software which your end users do not need. If this is what you mean the link I gave in my previous post will help you find the redistributable package.
Does this help?

my application is to be used for the creation of 3d graphics and also of presentations. Therefore in order to compile these dlls are required. In other forums it has been suggsted that they are in the GAC, would I find them thereor would I have to distribute thm myself?
Thanks

Compiling the application is something that the developer does. The user does not need to compile the application as they receive it in the compiled state.
The compiled version will need the appropriate assemblies to be available to it. This is why you need to redistribute the Managed DirectX assmeblies as you are not permitted to supply the SDK.

That is correct. You therefore need to supply the Managed DirectX redistributable with your applicaction. Its installer will make the appropriate checks and install itself if necessary.

Not really. My program compiles 3d graphics and presentations, that is what the problem is, not redistributables, etc which I am perfectly competent with. Thanks for trying though.

If you are competant with redistributables, then where is the problem distrubitng the DirectX SDK with your 3d compiler application?
|

What is wrong with that. You are creating a compiler with associated IDE (and one presumes documentation). My Visual Studio install is in excess of 1Gb (more if you include the MSDN library)
If your compiler is allowing its users access to the Mangaged DirectX APIs then I cannot see a problem with distributing the SDK (license permitting). If you are providing a layer of abstraction so that your users do not need to know anything about DirectX then you will be able to get away with the redistributable.

So what you are *really* asking, is "Can users of my app use all the cool features of DirectX without the 200 Mb install." - and the answer should be obvious to any developer.*
The pros and cons of this argument are the same as with the .NET re-distributable, and there are many topics here and many other places on this exact subject.
* Some redistributables can be broken down to core components, which tends to be alot smaller than the setup executable, you may want to investigate if this is an option with managed DirectX

Hi
Is there a way to add MSIL to c# code?
Thanks
|
|

Will ILASM not work?
Thank You

ILASM will work, but you won't be able to embed it inside C# code. You can build a DLL and call it from C#, tough, but I guess this is not what the original post wanted to do...
Yes, even I am blogging now!

Hello,
in class constructor, I have
public class oneclass : System.Windows.Forms.Form
{
...
public Thread th;
...
}
on events :
public void startsomethig()
{
...
try
{
...
}
catch(Exception ef)
{
MessageBox.Show("ef content: " + ef.Message);
}
}
private void Button1_Click(object sender, System.EventArgs e)
{
th = new Thread(new ThreadStart(startsomething));
th.Start();
}
private void Button2_Click(object sender, System.EventArgs e)
{
th.Abort();
}
How do I do if I push on button2 to stop the thread
the catch above don't must intercepte stop error thread aborted. ?
Thanks in advance.

Hope I got it right that you don't want to show a message box if the ThreadAbortException is catched in the startsomething method.
To achieve this, add an extra catch block for the ThreadAbortException:
public void startsomething()
{
try
{
...
}
catch (ThreadAbortException)
{
}
catch(Exception ef)
{
MessageBox.Show("ef content: " + ef.Message);
}
}

You have to use Thread.ResetAbort() in the catch statement, otherwise the ThreadAbortException is rethrown automatically by the CLR. This is how .NET works.

I have a registry called HKLM\SOFTWARE\MyReg, I do do not know the name of the subkeys or how many but every subkey contaians a string "value" that I want to read.
Here is a the code that runs when a nutton is clicked
-MessageBox (mess1) displays the correct path of new subkeys
-MessageBox(mess2) does not display anything.
Any help will be greatly appreciated
************************************************************************
string[] daemonKey = new string[12];
string Elem, newDKey, numElements;
int count;
newDKey="SOFTWARE\\MyReg\\";
RegistryKey OurKey = Registry.LocalMachine;
OurKey = OurKey.OpenSubKey("SOFTWARE\\MyReg",true);
//find all the subkeys
daemonKey = OurKey.GetSubKeyNames();
//how many found?
numElements = daemonKey.Length.ToString();
//convert string to int
count=Convert.ToInt32(numElements);
for(int i=0;i<=count-1; ++i)
{
//new path for the key to open
newDKey=newDKey+daemonKey[i];
//open the new registry
OurKey.OpenSubKey(newDKey,true);
MessageBox.Show(newDKey,"mess1",MessageBoxButtons.OK,MessageBoxIcon.Information); \\\\shows correct path
//read the value for the string called value
Elem=(string)OurKey.GetValue("value");
MessageBox.Show(Elem,"mess2",MessageBoxButtons.OK,MessageBoxIcon.Information); \\does not read the value,blank-nothing
//reset the key
newDKey="SOFTWARE\\SOFTWARE\\MyReg";

 Hi:
I have a strange problem where the controls location on the form is changing without me touching it's position. Like the designer is somehow doing it by it self. I am changing some code segment (not related to the location of the controls) and when I return to the designer - the controls are redrawn in a different location (mostly they are shifted down).
* I am using the "RightToLeft=True" property

how do I use c# to change user security permissions (policies)?
I know to use System.Security, but not really sure what to do after that. I searched the msdn articles, but I guess I'm not sure where to really look as most of the stuff there is about internet security, or application permissions.
thanks,
Stephen
