I want to create something similar to the C# Form Designer include in the C# IDE but not too advanced, I just want to know how can I lock a Form in my Main Application Window, anybody know how to make something like this ?
thanks.
BTW, is it possible to create a DLL with the other dll I need to create an application like System.DLL, System.Windows.Form.DLL all those DLL include in one So after I can only compile my program using this DLL ??? if yes how can I do this ?
Thanks Again

From what I can tell the VS.NET forms designer actually loads the form up into a temporary app domain and displays it in the window. To display a Form inside another form use this bit of code.
Form childForm = GetFormToDisplay();
childForm.TopLevel = false;
childForm.Location = GetLocation();
this.Controls.Add(childForm); You'll also have to hook several messages using Application.AddMessageFilter so that the child form can't be moved around (NCHITTEST plus some WM_SYSCOMMAND).
I have another message here that explains how to use Application.AddMessageFilter

k i will try to code it, if I need help again I will post another msg
BTW do you know how can I (suppose I have a button control) remove some property in the PropertyGrid and replace it by my own. In my application, I add a propertyGrid and I want to show only some property for some controls, how can I do this ?
Thanks Again James

Without creating your own class derived from PropertyGrid you can't replace specific properties with your own.
The property grid shows all properties with a BrowsableAttribute set to BrowsableAttribute.Yes. So you could create your own psuedo-button class that encapsulates a Button, and pass that as the SelectedObject in the property grid.

I believe you will need to do a childForm.Show() on that also. The Forms framework doesn't seem to do it for you.
I used this technique a little while back to implement a Wizard97 look-a-like that allowed users to design their own forms and feed it to the primary Wizard form (sheet), all the wizard had to do was adjust a few properties and drop it into the mix, works well.

LOL, yeah I always forget that; then wind up going over my code three times trying to find the bug

do you think you can send me a sample code of something like your Wizard app ?
at this moment it's going well but I think I will have problem later 
Thanks

Well, if you follow James instructions above, it should do you pretty well. I really don’t feel right about releasing my code for this just yet, as it’s running in a current client’s system.
Just shout when you need assistance and one of us will push you in the right direction, or possibly someone reading this may have something similar that they are a little more free to share.
A word of caution up front though, in the current release of the .NET framework, forms created in this manner do not receive their OnClosing/OnClosed events naturally, and you should probably issue a Close on them manually when the container form receives its notification. A second solution, which I used, was to issue a custom set of Wizard related events to signal that the parent was about to close and it was time for the form(s) to cleanup. Using this method protects my code from issuing a second Close, just in case the boys and gals over at MSFT decide to fix the issue. The dispose methods do get called regardless.

the only thing it's after the user create the form dynamicly I want to include action on some controls like buttons and I want to compile all the form with the controls action in one file *.cs and after compile it to an exe.
What I want to know it's how can I create the CS file to add the action and the form design in, like VC# does ?
Thanks

My wizard solution is something used by the clients developers, so it is more of a component than an application builder.
Just out of curiosity, and I am definitely not the one that would try to stifle your ambition, but why are you trying to reinvent the wheel that was just built?
It would seem to me that if you expose a good object model, extending an application built with .NET would be trivial without all of this, just having the clients developers use .NET to build extensions. Or are you looking for a mini environment like VBA in outlook?

I'm creating a Trainer Maker and I need to use a Form designer and I need to compile the form the user will create and I need to include some action like retreive the Textbox text to use it for a value and add Buttons action like to poke and freeze that's it.
I want to make something similar to Trainer Maker Kit (try to look at this application,check for screenshot, if you want of course), it's in VC++ i think and I want to make something that can equal the perfection of this program. Of course with the .NET Technology.
at this moment the form Designer works fine the only "hic" it's for that .CS file creating dynamicly. I'm suppose that is almost the same way as the C# IDE does, but i don't know very well how can I remake this. I don't want to make something big just a little file with the Window Form Designer code for all the controls and the action I will put on the controls.
I will check how can I figure it out, but I think I will post a lot of question on this board I hope I don't bugging you with all my questions, if it's the case just tell me please
Thanks

I think there is a sample in the C# section called LiveCode.NET that does something similar. I havent checked it out yet, but I am sure you have seen it in any event...

Oops, I don't think I ever posted that message explaining Application.AddMessageFilter 
AddMessageFilter takes an instance of the IMessageFilter interface, it has one method, PreFilterMessage which works like the WndProc except it returns true if the message has been filtered and doesn't need to be processed anymore.
So to use it:
public class MyClass : ......, IMessageFilter
{
bool IMessageFilter.PreFilterMessage(ref Message m)
{
return bShouldContinueProcessing;
}
}Then when you want to add it to the Message filter, Application.AddMessageFilter(myClass as IMessageFilter);

Nope, not with strongly-named assemblies they cannot be modified since a checksum is used to ensure they haven't changed.
There is a utility out there somewhere for combining multiple assemblies into one, but it can't be used on strong named assemblies because of the previously mentioned reasons.
I forget the name of the utility; maybe Rama Krishna remembers it (it was mentioned on the dotnet list not too long ago; if i remembered the context I could look it up).

My code gives different solutions under debug and release. Is this possible, if not what can be the error?

What do you mean by "gives different solutions"?

Can you tell us a little bit more on what your program does, and how you have coded it?

TreeView intensively use an Hashtable of node where only insertion and none removal ops are perform.
Could you explains how cleaning is handle?
1) Does this involves that despite of manually removing, Treenode always remains in memory during execution?
2) or is it due to (TreeNode)collection processing whom release dead node.
How does this works anyway? how null value are detected?
waiting for your help, thanxs cause a lot  now

It’s due to Elnino! ... No Seriously,
What you are probably seeing is the .NET garbage collector at work (or sleep, as it where), plus possibly the node (bucket?) caching mechanism in the internals of the TreeView itself. I haven’t bothered to drill down in enough detail to see if they are reusing their internal data structures of the later, but it’s a pretty fair assumption.
BTW, if you are holding on to a reference to a removed tree node to see if it goes away, it won’t happen... 
Cheers

just use ildasm: the (assembly) hastable is nodeTable. grep it in TreeNode* + TreeView, you'll found two Op is performed:
create (powerful),
adding in TreeNode.Realize: treeView.nodeTable[htreeitem] = this;
several reasons:
* The paradigm it's to inherits from TreeNode but pb is that data aren't released  .
* Notice that original removal is slowest enough without inheritance
if time must increase sic.
* What i mean it 's not caching but smth like MapHandle % MapPermanentHandle in MFC. Imagine if nodeTable grow without freeing anytime you use it.

I am trying to test some web services that are freely available on the internet (translators, weather, etc) using my Windows Forms client application. Problem is that I can't access any remote wsdl service description, I always get a message 'HTTP Status 407 - Proxy access denied'. Description for that message is that I don't have right authentication. I am supposedly cleared of any proxy interference on my side, is this a client side or a server side (proxy) message? At the same time all those services work fine when I access them using IE. I am probably missing something in the whole picture.
Any suggestions?
Regards,
Dejan Petrovic

HTTP status 407 is a server message.
I am willing to try to access services from my computer. Can you give me a web service IP?
