In C# winform, I have a main form which has menu to open up other forms. Now I want to add a button to close all the open forms expect this parent main form. Is that a way that I can quickly do it?
Thanks!

void CloseChildWForms()
{
   foreach(Form f in this.Controls)
   {
      f.Close();
   }
}

thats should work, i think. Big Grin | :-D

It depends if they are child forms or owned forms (the latter are not confined to being inside the owner form).

I don't know if ther is an OwnedForms collection, is there?

Alphanumeric Keys

Nnamdi Onyeyiri26-Aug-02 4:13

is there a way to detect if a key pressed is alphanumeric, as if i just caputre the OnKeyDown event, it also captures things like the shiftKey, which i do not want.

The KeyPressed Event should do this, regarding other question about caps lock, i had a quick look and couldnt find anything.

Hope this helps Smile | :)

How to tell if the caps lock is on

26-Aug-02 5:36

im working with the control class btw.

but i am using the OnKeyDown/Up to capture the events, i just wondered if i had to make a mtheod myself to work out if it is a letter, or if the framework already provided that ability.

Hi,

I need to integrate an interactive movie into a
Windows Application. I think that it is possible
to integrate Macromedia Flash 4 as an ActiveX
control into a host windows application.

Could you point me to an information source how
this can be done?

Thank you in advance.

it doesn't work this way in vc 5 I get some error message that the object cannot be imported
I'll try to soon with C#.
Is there any information about to FLash API and the activex object itself?

Well yes, the .ocx file must have the type-library built-in, which is very likely to be so.

web page fetching and cookies

Adding the Shockwave Flash ActiveX control (flash.ocx) should provided everything u need. I havent use it but will a look later. Smile | :)

UPDATE: Had a quick look, but the file does not load, but the ocx is displayed , like as if in a webbrowser Smile | :)

, but says , movie not loaded...

UPDATE2: use the Movie property to set swf file, in URL syntax, eg file:///D:/floder/test.swf . Smile | :)

Works like a charm, note, movie play in designer too if play property is set true.

Hello,
I would like fetche the contents of a web page.
I use
HttpWebRequest WReq = (HttpWebRequest)WebRequest.Create("http://www.aaa.bbb");
HttpWebResponse WResp = (HttpWebResponse)WReq.GetResponse()
StreamReader sr = new StreamReader(WResp.GetResponseStream(), Encoding.ASCII);
....
But if I want to access a certain internal site
HttpWebRequest WReq = (HttpWebRequest)WebRequest.Create("http://www.aaa.bbb/ccc");
HttpWebResponse WResp = (HttpWebResponse)WReq.GetResponse()
....
it Doesn't work.
Because the page demands cookies, where login and passwords are stored.
My question is - as I can send corredponding cookies from my harddrive with the Request, as this the Browser does?
Someone any ideas?

Yes, you can: you need to send/receive cookies in the HTTP request/response headers.

Interoperatioin with Shell32.dll COMObject...

I want to use COMObject in Shell32.dll, and I have ran "Regsvr32 -i shell32.dll", but when I create the object, vs.net tell me "ComObject is not valid or registered."
Following is my code:

<br />
try<br />
			{<br />
				Shell32.ShellLinkObjectClass link = new Shell32.ShellLinkObjectClass();<br />
				link.Path = "C:\\boot.ini";<br />
				link.Save("D:\\Mylink.lnk");<br />
			}<br />
			catch( System.Runtime.InteropServices.COMException ex )<br />
			{<br />
				MessageBox.Show( ex.Message );<br />
			}<br />

Thanks for your help! Rose | [Rose]

I am afraid you have to use interop services.

See this thread on Google.

From what I read in MSDN, you'll have to call the WIN32 API SHGetDesktopFolder() to retrieve the IShellFolder interface, then use either a direct cast to (IShellLinkObject) or use IShellFolder::GetUIObjectOf(...).

Once you've got the IShellLinkObject, you can use the Path method call to set the path, but to do the Save it is a little harder : cast this interface to (IPersistFile) than you'll gain access to the Save method. Big Grin | :-D

I know this ain't easy because the parameters passed need marshaling, but I hope the thread on Google provides you all you need,

PS : I believe the fact you can not directly create a ShellLinkObjectClass instance is due to bad tlbimp from .Net. This is not the first bug, this is not the last either I am fraid....

But I think ShellLinkObjectClass should be created. Frown | :(

Stephane Rodriguez.26-Aug-02 1:26

26-Aug-02 1:26

I believe this object fails to be created because of a wrong interop class factory. I guess that, instead of using low-level interop -which is definitely the way to go when you are stuck-, there is a solution by explicitely asking the .Net framework to create a factory for us :

Marshal.CreateWrapperOfType(o, typeof(Shell32.ShellLinkObjectClass)); or Marshal.CreateWrapperOfType(o, typeof(IShellLinkObject));

Try to get a working sample about that,

And I swallow a small raisin.
