View 2 RepliesI have developed a windows application for my company. It is a multi user software and we are using sql 2008 as the database. The sql 2008 is installed in our company server. Within our LAN, there is no problem in accessing the software and its working pretty fine.
Now the problem is, some of the managers need to go out frequently(for business tour and all) and they need access to this software. The software is already installed in their laptops.Is there any way to access the database that is in our company server ???
We have few static IPs with us, is there any way i can use that here (Using NAT in the firewall or something)?
Basically back in VB6 days, I created several VB6 apps with Access as the backend database. I'd package my Access db file with the application setup, which copied it on to a shared network drive, and then different computers on the LAN could use the same backend database file, and that worked just fine. With SQL and VB .Net, I've done work with a SQL database hosted on a remote server, so you can basically build your query string easily and anyone can connect to it from anywhere, and it works just fine.However, what I'd like to do is have a local SQL express database as the backend for a VB .Net application and make a setup program that can install it in a way that it could be shared on a Local area network, without the user who is installing the application do anything.
I know about building a connection string with the local machine name, but I don't really have any experience with including an actual MDF file with the application. Does anyone know how it works, and is it a better approach? Does it work similar to placing an access file in a shared unc path?I know that ClickOnce (which is awesome) can install SQL express easily on a user's machine. However, the key is that I want SQL express to be installed only on the machine that is going to be the database server in a LAN enviornment, and not on every machine, unless it is neccesseary. And then how does your VB app know how to build the connection string to access the database from any machine on the local share?
I'm trying to make a chat application in Vb what uses MySQL database.
Here is the code for the UpdateChat()sub

Now it gives me there error that a connection is allready open with the Datareader (I havea timer running this sub once in a while).
im trying to make a little application that will read an fps server chat log.the chat logs are plain text files that come in the format :
Billy says: yada yada yada
Bob says: mooo
on certain key phrases (which will be user defined) it will reply (also user defined) now my problems. (there are many). most of which stem from not actually knowing any syntax for this language.firstly im suffering something of a huge brain fart with trying to read only the last line. i have it currently reading though the whole file and counting line numbers but then i just hit a wall . what do i do with the line number? i cant find a simple way to stop and come then have it check again after a couple of seconds for a new line? allegedly filestream can seek the end of the file however all my attempts to do anything with filestream have met with absolutle failure.
this is what i currently have for this, and it works to some degree
FileReader = New IO.StreamReader(OpenFileDialog1.FileName)
Do While FileReader.Peek <> -1
txtln = FileReader.ReadLine()
[code]....
i have the remnants of both the options ive considered in there, and its almost doing what i need it to . i just have no idea what to put into the last section to make it wait for another line to be added to the text file, or use the linenumber to make it check back from there for more lines. i cant seem to find a wait/sleep/pause so i just dont know.
my other problem is one of file access. i am aware of some properties of filestream that allow for a shared read/write access for other programs . however as i stated before . i have had no success even getting this simple peice of code to work with filestream.
If I decide to build this, this would probably be my first "large" project i've ever done myself.What I am looking to build is a very simple Chat/IM client to use for the users in our office network. It would just call us their Windows logon name and use that to IM and the like. I'm talking a very simple client, with a list of names of people who are logged into the network, and option to IM them and an option to do a multiple user chat. It doesn't have to be visually stunning.
View 1 Repliesim making an application and i need to install a printer in a computer. The application im trying to do is a client-server application so the idea is that the server send the instruction to the client telling him what to do and then the client will do it, in this case it will go to a SAMBA directory and it will get the drivers for the printer model from there and after that it will install the printer, everything in silent mode.

View 3 RepliesI was thinking to make an app to save images [or download images] to local hard disk. But to keep it easy, I want this app to create a small picturebox on form to show the thumbnail of downloaded image. Lets say a 5 pictureboxes has to be added with the thumbnails to show the recent downloads. A user can save the location where he wants to save the files on hard disk. A listbox or a dropdown menu will help in categorizing the images, like image1 in friends section, image2 in family section, image3 in others, etc... When the program restarts all the latest 5 thumbnails has to be loaded in pictureboxes and the directory that was chosen. Finally, a button that shows the downloaded images into original image file size one by one or a slide show. Is it possible to make such program?

im trying to make a chat program.im already done with the chat but i dont have any idea now to make the video.
For the chat i used this :(url)
There are a series of web requests, database handling using php as well as using mysql connector. There are at most 5 timers in one window. some window has 3 or 2 timers as needed.Among some features there is a feature for chat. and I'm doing it with Remote mysql connection using mysql data connector.I'm not much familiar with VB.NET coding environment as well as with optimization issues. However made that app running with some problem, that is, when chatting, sometimes its not working smoothly sometimes stops for 4-5 secs then again responding. I'm not sure if this is happening because of timers. However a chat window has 2 timers of 1sec each.
