I have an application whereby several people in my office will use it for a number of duties we are all on the same network but everyone will not be logged in at one time.I want to enable the tcpclient class I guess as I want one user to be able to send another user a message etc.The problem is I don't have a central server where I can keep the internal IP of each user is is logged in etc. is there a way around this?
View 1 RepliesI'm planning to make multiple projects, which could connect (or comminicate) together. It's like a designing Network Program. There'll be a main program and some sub programs. These sub programs will send the informations about other computers which is on my network to the main program. If you ask "Why do you need to get infos about other computers?" ,then let me explain. I'm using limited internet connection and I'm not the only one who's using this wireless network. If I get over the limit, I'm paying some limit-upper fee. So, I've to control others internet usage to not to get over the limit. I've just made a small download counter program for my pc, but as I said, I want to convert it to a bigger project, with network solution. Could anyone refer me any resource, or show me any starting point?
View 4 RepliesWe have around 2000 staff. Each has a shared drive to store some of their files. This shared drive points to a central location on our network.[code]...
Each user will have a folder within the root "ournetwork" labeled with their username. I do not have to worry about the directory creation as that's already done for me. These users are all tied into our AD for authentication. Folder name == AD username.
We would like the ability to allow our users to access their mapped "F" drive from outside our network through a web page. I understand that the programming involved (assuming it comes to that) will not rely on their mapped drive but rather the UNC path as posted above.
I am open to suggestions on how to get this accomplished. ASP.NET? Is there just an IIS solution like WebDAV? (although client-side WebDAV on win 7 seems to be broken, so that may be off the table).

View 1 RepliesI am currently designing a calibration system for some equipment and want to be able to create a simple interface (initially) that will read real time samples from the Agilent 34970A (Data Acquisition Unit) and display them in a text box continuously until a separate button is pressed, which would interrupt the process. Here is some of my
Private Sub StartSampleButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles StartSampleButton.Click
ioDmm.WriteString("MEAS:VOLT:DC? AUTO,MAX,(@101)")
RealTimeSample.Text = ioDmm.ReadNumber
End Sub
When I press the StartSampleButton, it takes a single sample from the 34970A and places the result in the RealTimeSample box (no problems here). The problem comes in when I want to do multiple samples. I've been trying something along the lines of:
Private Sub StartSampleButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles StartSampleButton.Click
While 1
ioDmm.WriteString("MEAS:VOLT:DC? AUTO,MAX, (@101)")

View 5 RepliesI'm working on a windows forms application and would like to incorporate a feature that would allow me to pull the video stream from a networked DVR source. I have an existing desktop program that I may be able to use to snoop out some of the protocols used, but I have absolutely no idea where to look for a library or api to actually display the video.
Has anyone successfully done this? (Connected to a remote DVR, played realtime video in their own application)
how I should go about getting the names of the computers on a network. And if the comp had file sharing on, get the "tree" of dirs on the computer. Would I need to authenticate myself in order to read/write actual files to it?
how to even get started, so I don't have any code - the best thing I can think about doing is getting the tree of "\\network" or something. (forgot what it was called)
find some code (or give some search keywords or names of APIs) that would allow me to see and write/create files on a networked comp.

I'm working on a little app which needs to recieve information from a script on a web server. I tried to have the vb.net app pole a php web page for a command every half of a second. This worked but, the app is streaming video and every time the app needs to pole the webpage the video stutter stops. I tried setting the pole timer to 5 seconds and still every 5 seconds the video stutters. I thought that maybe sockets would be the answer, so I looked for examples of vb.net socket servers and php socket clients. I tried implementing a solution but the php cannot seem to connect to the vb.net server. I googled around and saw that maybe php cannot communicate with a vb.net application.

The current problem is that in each program a user needs to be logged into to use. If the user is logged into one, and clicks a button to launch another, it should pass who is logged in so they do not need to log in again in the second program.
