Re: Data Encoding (System.Text.Encoding) Neil Van Note5-Apr-02 19:48 Neil Van Note 5-Apr-02 19:48  I am not sure what you are trying to achieve, but the types of files you are talking about wouldn't have a text encoding. They are straight 8 bit with no encoding. Re: Data Encoding (System.Text.Encoding) BLaZiNiX5-Apr-02 20:17 BLaZiNiX 5-Apr-02 20:17  Thanks for the tips BTW what's mean UTF-7 UTF-8 ?? is it something like UNICODE TEXT FORMATTER ? thanks again Re: Data Encoding (System.Text.Encoding) Neil Van Note5-Apr-02 20:30 Neil Van Note 5-Apr-02 20:30  Yes. If you do a search in MSDN you will get an abundance of information. Regards Re: Data Encoding (System.Text.Encoding) BLaZiNiX5-Apr-02 21:30 BLaZiNiX 5-Apr-02 21:30  I search MSDN and the error I got in my program what reliated to UTF-16 so UnicodeEncoding but it's not working anyway. I don't know why I got this error because If i test it on multiple files like TXT Files I don't have any trouble but when i'm talking about EXE and Archive i got error. That Strange !! anyway if anybody have the answer or if you want me to send you my sample, just beep me jonathan.pouliot@tecksys.com ICQ : 71682311 Thanks Re: Data Encoding (System.Text.Encoding) Neil Van Note5-Apr-02 21:39 Neil Van Note 5-Apr-02 21:39  Sure, send a sample, and I will get it to work. The statement in your original post, "I created a multiple file tools" didn't give me a lot of insight on what you are trying to achieve, sorry. Email: vannote@netaxs.com Regards Doing a simplistic 'extender provider' Zombies with Coffee, LLC5-Apr-02 10:56 Zombies with Coffee, LLC 5-Apr-02 10:56  I've really tried to make sense out of the extender provider samples, but not a one of them does the same way, and none of them are relatively trivial. What I am looking for is the ability to add one simple 'boolean' to every object on my form. Sounds simple... So what am I doing wrong? I added on a project to my main application and created a component of out this. I can get it to show up, but in no combination of aggravation can I make the boolean property appear on the controls. Can anyone help me out!

You need to tell the UI what type of objects you want the property to appear for. It works out the type your property will provide from the GetStatusMessage and its return type. I can send you an example I have that I wrote which provides a simple extender to a control. I was going to write it up as an article, but I dont haev time. -- David Wengier Sonork ID: 100.14177 - Ch00k TCP/IP in C# Nick Parker5-Apr-02 7:00 Nick Parker 5-Apr-02 7:00  Suppose someone were writing a "firewall" application that was "watching" or listening for activity over an incoming IP address, what is the best way to cover all ports. In all the examples I have read, someone creates an instance of TcpListener and supplies a port to listen to. Surely you don't have to do that for each of the 65,000+ ports. Could someone lead me in the right direction. Thanks. Nick Parker Re: TCP/IP in C# James T. Johnson5-Apr-02 14:41 James T. Johnson 5-Apr-02 14:41  There is probably some winsock/system hook buried somewhere deep in the win32 API, that tells you when there is an inbound connection request. I looked at SetWindowsHookEx but it didn't seem to offer it, and I didn't see anything in the WinSock API. Perhaps someone more knowledgeable than me can fill you in, in the VC++ forum. Once you find it, you can use P/Invoke to access it. Or at the most you would have to write a MC++ layer to act as the middleman for your C# code and the system.

Self Extractor BLaZiNiX4-Apr-02 17:36 BLaZiNiX 4-Apr-02 17:36  How Can I make my own self extractor without using any zipping lib, I just want to add multiple file to an exe and when I double click on this exe : show a dialog with a browse to folder where the user want to extract files ??? Thanks Re: Self Extractor James T. Johnson4-Apr-02 23:54 James T. Johnson 4-Apr-02 23:54  You could add each file as a resource to an executable, then use the Assembly.GetManifestStreamNames/Assembly.GetManifestStream methods to loop through all the files added as resources parsing the name to determine if a folder should be created (or adding a special file which contains that data).

Zombies with Coffee, LLC4-Apr-02 10:22 Zombies with Coffee, LLC 4-Apr-02 10:22  Use your mouse to go over any menu item on any program. The status bar updates automatically with a description that you've added. How do you do it with C#? Thanks!! Re: How does the menu update the status bar? David Wengier4-Apr-02 11:02 David Wengier 4-Apr-02 11:02  Handle the Select event of the MenuItem and just set the status bar text (or anything else) as you wish. -- David Wengier Sonork ID: 100.14177 - Ch00k Re: How does the menu update the status bar? Zombies with Coffee, LLC4-Apr-02 11:17 Zombies with Coffee, LLC 4-Apr-02 11:17  Yep, that definitely helps. Is there any way of doing it automatically (as I'm used to in MFC)? Or do I have to make one gigantic 'if' statement with the text that I want to display? Re: How does the menu update the status bar? David Wengier4-Apr-02 11:21 David Wengier 4-Apr-02 11:21  I dont know about doing it automatically, but you could always create your own derived MenuItem class, or an ExtenderProvider that would do it. -- David Wengier Sonork ID: 100.14177 - Ch00k Re: How does the menu update the status bar? Zombies with Coffee, LLC4-Apr-02 11:26 Zombies with Coffee, LLC 4-Apr-02 11:26  True, I saw some examples in Petzold. But then wouldn't you loose the capability of using the IDE to create your menus? I currently have the following code snippet for the display on the status bar. private void MenuLoad_Select(object sender, System.EventArgs e) { MenuItem oMenuItem = sender as MenuItem; if( oMenuItem != null ) { switch( oMenuItem.Text ) { case "&Open": StatusBarMessage.Text = "Open up the file"; break; case "&Save": StatusBarMessage.Text = "Save the file to the disk"; break; } } } Re: How does the menu update the status bar? David Wengier4-Apr-02 11:34 David Wengier 4-Apr-02 11:34  If you are overriding the menus but not any of the drawing code (DrawItem and MeasureItem) then I would guess that the IDE should handle it, but I dont know. Try it and find out. An extender provider would certainly not affect the IDE. Probably the easiest way to do this would just be to buildup a collection of messages. This saves the interface, but doesnt allow you to set the menu help text in the forms designer. -- David Wengier Sonork ID: 100.14177 - Ch00k
