View 1 RepliesInfo: Multithreaded Server Socket Program Or Client/Server?
Oct 26, 2011I made a simple TCP server (I've found the example on the web) in VB to receive data from about 40 TCP clients.The clients are not synchronized but sends data about every 18 minutes; the problem is sometimes several clients sends data at the same moment, so I can't receive data.I also made a second program that reads the data (server program writes data on a file, read from the second program) scheduled.
My question is this: I've seen on the web examples about Multithreaded Server Socket Program, so I suppose this could manage my 40 clients (but now the clients are syncronized and send data at the same time in client mode) or is better get data (I have a central client that asks data to all 40 devices in server mode)?
Second question: can I make a single program where I run both TCP client and TCP server at the same time?

Public Function GetInfo(ByVal playlistname As String) As String

I pretty much understood how to write text to a file, but I cannot grasp how to READ the information. After I read the information, I would like to add each seperate line to a ListBox. Each line in the text file is a file path for a music file, as the file I wish to read information from is a "custom extension" playlist file. I know what to do after I get the file path, but I do not know how to get the file path from the playlist.

View 1 RepliesFile I/O And Registry :: Using The SaveFileDialog To Save Listbox Info Into A Text File?
Mar 17, 2010I'm using the SaveFileDialog to save listbox info into a text file. The files save fine, but when you go to save the file, if you hit the cancel button, it will overwrite the previous file you saved, because it's name was the same and it seems to save the previous file as the new name for your next file. Is there any way to catch if the user clicks cancel, and then exiting the sub if they did?

Oct 3, 2011[code]After spending hours of research.I finally figured out the vb.net version on how to read a 64 bit registry with a 32 bit .net application. The importance of this is when you try to write to one part of the registry, it gets redirected somewhere else in the registry, which is super annoying.[code]

Apr 28, 2012I was unable to find anything in my searches for XML or INI on the forum so i apologize now if this has already been asked and answered before.
I have been searching Google for days now, trying to find information on Reading and Writing XML files. I wish to use them to replace INI files in my programs.
I have been using VB6 for years now, but was able to get a copy of VB.NET 2003 really cheap and so i am trying to learn how to do the things i did in VB6 in VB.NET 2003.
I was able to find code to write to an INI file, but was not able to successfully read from an INI file with any of the code i found.
I have been able to find code to write an XML file, but when i try to update it, it replaces the old file with a new one, and the old settings are missing, instead of the new settings added to it.
i can at least start migrating to VB.NET 2003, or if you read XML and update XML data, i can switch now. Here is the code i have for writing XML.[code...]
