Re: Development limitations of Express Edition? Vikram A Punathambekar6-Jul-07 22:12 Vikram A Punathambekar 6-Jul-07 22:12  It's been a couple of months since I used VSE, so I don't remember exactly. Could you please tell me how you created multiple projects in a solution? Cheers, Vıkram. After all is said and done, much is said and little is done. Re: Development limitations of Express Edition? urbane.tiger8-Jul-07 16:14 urbane.tiger 8-Jul-07 16:14  left click on Solution item in SolutionExplorer (ie the first item) and select Add Project, Select New or Existing ..... I think you can also do same from File menu, don't have VSE in front of me right now. Also I think the Express version doesn't have all of the templates that the full version has, nor all of the bits required to build "releasable" products eg I don't think signing is available.

Player A hosts a "game room" and creates a game object. Then players B and C gain remote access to that object over a TCP connection. (Assume everyone knows everyone else's IP address). My issue is that player C's UI needs to be updated when player B calls a function on the remote game object. When the program tries to register player C's handler onto the game object's event, I get an exception telling me that my security settings are too low for deserialization. (Specifically: Type System.DelegateSerializationHolder and the types derived from it (such as System.DelegateSerializationHolder) are not permitted to be deserialized at this security level.) The message suggests using security certificates to get around all this, but I don't know how this is done. Can someone instruct me on how to get this working? I would really rather not have the host player have to gain remote access to each other play so it can call some "updateUI" function on each player. Emulating ANSI in a TextBox weis234-Jul-07 14:18 weis23 4-Jul-07 14:18  Hi there! I'm an amateur programmer doing a "for fun" project, and am looking for some helpful advice. I'm trying to make a terminal emulator that can emulate ANSI (ANSI X3.64, aka pretty colors in a telnet session) for the purpose of connecting to old BBS software and playing the games of my youth. I already have the Telnet part nailed thanks to a fine article from this site, but the ANSI emulation is starting to look pretty daunting. My question: Is the best way to do this to use the TextBox component? Changing text color is no problem, but ANSI has escape sequences to move the cursor around, and most BBS software uses them heavily. For instance, if I encountered an ANSI sequence that means "move the cursor to row 3, col 10, and print the letter A", I'm not sure what the "right" way to do that in a TextBox would be. The best way I can think of is to pre-populate the TextBox.Text string with enough spaces to fill the screen, and then replace the character at position ((number of columns on the screen * 2) + 10) of the string, but that seems hideously inelegant. Alternately, is there some other component that would be better suited to this? Should I be leveraging existing ANSI support from somewhere, like ANSI.SYS? Any suggestions are welcome, and thanks in advance. Re: Emulating ANSI in a TextBox Luc Pattyn4-Jul-07 15:53 Luc Pattyn 4-Jul-07 15:53  Hi, I tend to use TextBox only for single-line or few-lines stuff. For an editor or a terminal, I would choose between: - a Panel, i.e. doing it all myself (data structures, paint handler, etc) - a ListBox although I admit you can do it with a TextBox too. the advantages of ListBox are: - treats lines as separate objects; this is both easy to use and fast (TextBox concatenates all text lines to a single string) - knows how to draw a line of text (but also supports user drawing) - scrolling could mean: remove topmost text line, add new text line at bottom (so make sure to never hold more than 25 lines) - emulating terminal with buffer larger than display height is free: use vertical scrollbar (keep the LB 25 lines high), and let it scroll when more lines have been added to it Hope this helps. Luc Pattyn [My Articles] [Forum Guidelines] Re: Emulating ANSI in a TextBox weis235-Jul-07 14:56 weis23 5-Jul-07 14:56  Thanks Luc, I had not considered a ListBox because I thought it would be unsuitable for my purpose; For one thing, the user wouldn't be able to highlight and copy text that spans multiple rows. For another, I can't control the color of the LB items letter by letter, can I? And for a third, I didn't know LB's could add new items to the bottom, as opposed to the top. (And I still can't figure out how to do that) I guess I will have to go back to the drawing board on this one, or pick a simpler project, as starting with a panel and doing it all myself is probably beyond me at this point. Thanks anyway though. Re: Emulating ANSI in a TextBox Luc Pattyn5-Jul-07 15:21 Luc Pattyn 5-Jul-07 15:21  Hi, 1. yes selection across multiple lines would be a problem. 2. by default lines get drawn in single font, size, color as in a regular TextBox (as opposed to a RichTextBox). Character coloring (or anything else fancy) would require you choose the OwnerDrawn model, in which you provide the code to paint each line yourself (a simple Graphics.DrawString would again offer the default behavior). 3. yes, maipulating lines is easy through the ListBox.Items property, which lets you add, remove, insert, and modify lines, either through methods or by using an indexor. Conclusion: if you need all the fancy coloring and free selection, then ListBox is not an option, and you must either go for RichTextBox (and live with degrading performance in case the text gets really large, which is unlikely in your app), or go for a Panel and do it all yourself. BTW Come to think of it, I am not sure you can do all required selection stuff with what a (Rich)TextBox offers; I am not sure how far an ANSI terminal would go, IIRC a VT-220 could have multiple selections, some steady some blinking... Cheers. Luc Pattyn [My Articles] [Forum Guidelines] Re: Emulating ANSI in a TextBox weis235-Jul-07 16:01 weis23 5-Jul-07 16:01  Thanks for the advice Luc, it sounds like I just need to do the terminal from the ground up, or change the design completely. I'm thinking perhaps I will make a localhost proxy for a telnet session to go through (using Windows telnet, with its built-in ANSI support). That way I can capture text from the session and use it to populate a db, and then make a companion app that does things with the data in the db. Once again, thanks for helping a beginner, I'm glad I didn't spend too much time trying to do this the wrong way. Re: Emulating ANSI in a TextBox Luc Pattyn5-Jul-07 16:38 Luc Pattyn 5-Jul-07 16:38  You're welcome. Luc Pattyn [My Articles] [Forum Guidelines] Re: Emulating ANSI in a TextBox weis235-Jul-07 17:01 weis23 5-Jul-07 17:01  Sorry to keep dragging this out, but a thought occurred to me: would it be possible to just spawn a command prompt inside a Windows form and run the standard telnet.exe through it? As long as I could send input to it and read what it outputs, that would get me where I need to go, since cmd includes ANSI support via ANSI.sys. I know I can spawn .bat's and .exe's as external processes, but I don't know if it's possible to do something like that within a form and interact with it. Thanks again in advance. Re: Emulating ANSI in a TextBox Luc Pattyn5-Jul-07 23:43 Luc Pattyn 5-Jul-07 23:43  Hi, in general this is possible. You need the Process class to do it, and you should: - either redirect Input, Output and Error streams (and create 3 separate threads to handle them) but that would not solve your problem, since then you have to show it again, - or adopt its Window into your app; IIRC I read a CodeProject article on that but I have forgotten the details on how to do it. Sorry.

I've been experimenting with overriding the WndProc() method but cant seem to achieve what i want. Any idea would be greatly appreciated. Regards, Mark. Re: listbox scrollbar Luc Pattyn4-Jul-07 13:37 Luc Pattyn 4-Jul-07 13:37  Hi, I dont think there is any event related to scrolling. What would you want to do with a scroll event ? maybe you could use the Paint event and check whether TopIndex has changed.

Joseph Guadagno http://www.josephguadagno.net time out exception while uploading to FTP [modified] Iftekhar Naim4-Jul-07 7:04 Iftekhar Naim 4-Jul-07 7:04  I have developed an application that will upload files to FTP Server as part of its task. Now it works quite well most of the time. But sometimes it gets web exception-called timeout exception - System.Net.WebException: The operation has timed out. at System.Net.FtpWebRequest.GetRequestStream() I searched in google and didn't find any useful help. I saw an attibute (in FtpWebRequest class) called Timeout. I didn't set any value to it, cause i assumed that the default value will do. But now that it gets timeout exceptions , what should i do? 1. Can i solve it Just by setting some high value in this(timeout) attribute ? will it have any performance overhead ? 2. I am using FtpWebRequest. I am sending synchronous calls. Do I need to change it to asynchronous calls or it will be all the same? Is there any relation between time out and Sync/ASync calls ? I am finding no solution to this. So i will be waiting for a help from this forum. thanks -- modified at 13:46 Wednesday 4th July, 2007 Chayan gmail notifier when a new mail comes mfmaneef4-Jul-07 5:26 mfmaneef 4-Jul-07 5:26  hello, i went through the articles in CP and i found some good samples to create a gmail notifier using gmail feeds..but i want to know is it possible to create an application to notify instantly whenever an email comes to my gmail account..something like in google talk or yahoo messenger aneef
