Thanks & Regards Re: C# Main Menu Dario Solera10-Aug-05 1:30 Dario Solera 10-Aug-05 1:30  If you use MDI forms (Multi Document Intercace) that behavior is normal and expected. What do you intend with parent and child forms? How do you open the child form? [ITA] Tozzi ha ragione: Gaia si sta liberando di noi. [ENG] Tozzi is right: Gaia is obliterating us. Re: C# Main Menu shafqaat10-Aug-05 2:54 shafqaat 10-Aug-05 2:54  Dario Solera Thanks for ur message.

Thanks read and write at the same time nidhelp9-Aug-05 19:27 nidhelp 9-Aug-05 19:27  Hi all! i have a read and write function which call from method in other class.. instead of either can read or write at a time,i want to make it both can work at the same time(i want to communicated via serial port).Does anybody know how to do it? using System; using System.Text; namespace yong { public class Class2 { static void Main(string[] args) { // Convert string to byte array and send string x = Console.ReadLine(); byte[] byteDateLine = Encoding.ASCII.GetBytes( x.ToCharArray() ); port CommPort = new port(); CommPort.Open(); CommPort.Write(byteDateLine); //Convert Byte to String //string sBuffer = Encoding.ASCII.GetString(dcbCommPort.Read(10)); //Console.WriteLine( sBuffer.ToString() ); } } } Re: read and write at the same time Christian Graus9-Aug-05 19:31 Christian Graus 9-Aug-05 19:31  Assuming hte port allows it, try running the methods on different threads. Otherwise, each method will only be called when the last method ends. Why do you need them to be intermixed ? I suspect the end result will be the same, in terms of speed, unless you're on a multi CPU machine.

MSDN[^] has plenty of example code. levi`s wrote: How about i use While loop and at the same time inside the While loop contain a if-else loop? Well, they would still be on the same thread, but if you put the write and read code in the same loop, that would make them both happen together, but I don't see how it would get faster as a result.

Re: read and write at the same time Christian Graus10-Aug-05 17:08 Christian Graus 10-Aug-05 17:08  Using threads is cleaner, but the code is a lot harder to debug, and I doubt it will be any faster, it will just be interspersed, which seems to be what you're hoping for. If you read the MSDN articles, they should give you a good start. Whatever you try, just post your code here if you get stuck ( i.e. as a new question ) and I'd be happy to help.

No, mySQL is kind of crap. If you want a free database, try MSDE, or SQL Server Express[^]. nidhelp wrote: how do i go about creating the database and adding sample data to the database? Buy a book on SQL, or download the documentation and samples and look through them. nidhelp wrote: after that is done i also want to retrieve data from database to my form as well as to update data from my form to database... Again, look through the samples first, read the books online ( assuming they come with Express Ed. ), etc. Christian Graus - Microsoft MVP - C++ Re: create a database nidhelp9-Aug-05 19:34 nidhelp 9-Aug-05 19:34  ok thanks, what about oracle developer tools for visual studio .net ?? is this an easy-to-use database?

I've also spent the past few hours looking for step-to-step guide to start using and creating a database. However, up till now I still have no idea how to start using this sql server express. Im wondering, is visual studio .net 2003 compatible with microsoft sql 2005 server express? This is because I only see Deep Integration with Visual Studio 2005 titles/headings associated with microsoft sql 2005 server express. I would like to know what are the different database systems available that can be used with visual studio . net 2003 (yes, not 2005).. Thanks!

Im starting to get the hang of this programming business Kampai!!! Re: TimeOut tatchung9-Aug-05 17:48 tatchung 9-Aug-05 17:48  Oh hey I've got another question... Does the ScriptTimeout works like the Page.Response.Expire? I just found the function while exploring Page members. I mean aside from property sets which is in minutes. Thanx! Kampai!!! Re: TimeOut Christian Graus9-Aug-05 17:51 Christian Graus 9-Aug-05 17:51  I have no idea sorry, I just googled it Christian Graus - Microsoft MVP - C++ Re: TimeOut tatchung9-Aug-05 17:52 tatchung 9-Aug-05 17:52  Thanx Chris!
