Allow Comunication Between Two Computer On Diffrent Networks?
Feb 23, 2010
I am working on a video chat program and I have almost everything working on my network I now need to figure out how to establish comunication between two clients from diffrent networks without having a middle person to switch each meassage to each other.
To clarify: I belive that I need to have a server running that each client when they start up the program will login to the server handing thier external ipaddress and port forward to get to each respective client, this will be stored in a SQL database (I know how to add the data just not hwo to get it from the source)
Then the server would brodcast the clients name to anyone that is authorized to know (currently everyone) and has there data stored on the server.Finnaly when the client shouts down it sends out the logging-off comand and deletes the adressing information from the server.The client programs will be windows form applications that use the tcpclient connection to send text meassage And the server application will be I hope a webapp.

Now I know whats going to happen, I will post a request for code syntax and one of the admins is going to say that I need to post the code I already have. The code I already have is irrelevant to what i wish to do. So, continuing on; I have a micro controller that i wish to send commands to it in HEX data type. Communication is via the serial port RS232. (well technically its through the USB to serial converter)Steps:
1) Sending a "001" tells the micro controller to await instructions as to what to set the duty cycle to
2) The data that follows i.e." 050, 010, 185 " will be added to 400 (by the micro controller) to come up with a duty cycle based on a 10 bit resolution of 0-1024. I am only going to be using the range of 401- ~500.
I can communicate with the micro controller via hyper terminal. Using the Alt + #keys method I can transmit data to the micro controller, and this is what i with to do with vb.net.[code]

I have a matrix for example (10 x 10) which represents 10 nodes. The matrix called MyMat(9,9) The rows of this matrix represent the source node (From Node) and the columns represents target node (To Node). It has 14 links which are randomly distributed. The non zero values represent the connections between nodes.

I have a form with two listboxes. The user selected the directory using a FolderBrowserDialog1 then my program searches the directory and displays a list of files. They them select the files they want to store under a project name and the names are placed in a database. My problem is it stores the mapped file path not the network path. (ie N:examples estfile.txt I need \myserverexamples estfiles.txt) That is because the person that reads this database may not have their network drives mapped to the same letters.

I need test data for a IP Subnet calculator I have developed. I have tested some obvious scenarios, and all seems good, but the person developing can often be the wrong person to test.
The calculator can do one of two things:
1 - Given an existing network and CIDR (mask), and a new CIDR it will create a number of networks with the appropriate number of hosts.
2 - Given an existing network and CIDR (mask), and a list of c,h, (c = count, h=number of hosts) it will create the networks.

I am using VB 2008 and doing the project on office 2007. I've created a Ribbon (Visual Designer) and put a button. Now thats all I've done. I'm still researching on how to make it so that when I press the button , a box will appear and at the side of the box will be something like" Search, Stop, Select, Cancel" buttons the box will be a container where when search is pressed, the wireless/LAN connections will be displayed.

i have an application. this application is using findwindowa api for check if there is instance of its own. (sorry for english) so we cannot open this app two times. as you may guess i wanna open thousands instance of its. (or 2-3). i tried disassambler but code is encrytped or something like that. so what can i do? maybe i can:
* run app from diffrent application. if its possible findwindowa can fail.
* change class or window name (i think its not possible)
* block applications findwindowa call

I'm done with a solution and I don't want to work with it anymore, except for small bug fixes that may come up. I have a new project assigned to me which to take the project I just finished, and add some new features to it. But I wouuld be changing alot of stuff in this program. So I want to copy my solution, save it as a diffrent name, so I can work off the old solution and start modifying it, but I will always have the original one to fix any bugs or go back to.

I wanted to visualize to the user the diffrence if they opted for certain values. In mycase certain choises would show phonenumbers on intranet.To show how I wil leave the control names default. To recreate the the project. Start a windows form application, place a datagridview, and 2 bindingsources on the form To start we need some data to show and a list to choose from.To make a simple example I chosen to make a person class containing an Id, Name and Position.Id If the Position is a staff position it should be blue others should remain the default style.But lets start with the colorScheme Interface so we can store the colorscheme we want to show for a certain positionitem in the datagrdview It wil need back and forecolors but also colors for teh item whilst selected. To show the Displaymember we want to see I've also added the toString property that should shadow the toString of the object.[code]

So I am working on a small program that will tell the engineers the status of their testers; whether they are up or down with the time and date in addition there is also a comment box. I have created a program that has all the right buttons and options. Where I am stuck is on the save option. I want the engineers to be able to make changes to the status/date/comments and by clicking the save button to save all changes(in the status and date boxes) and text(in the comment box) so that when the program is opened at a later time or by another user on the network from a diffrent work station the latest changes from whomever will be present. The code that follows only allows the changes to be seen by on that specific computer and they are not shared to everyone who uses the program that accesses it over the network. Any help would be awsome!! Hope this is clear!
How can I get it so everyone sees all changes over the network regardless of the computer they are using? any help would be amazing!!

Before I start, I'm not 100% sure this is the right place to ask. Okey, so I'm making my own Notepad, which will contain newer features. (Private use only though) One of them being tab control.
Now I want the program to be in the "Open With..." menus for all files, so I can choose myself.
And if the program is already running when user opens a new file, I want the text to appear in a new tab, instead of a new window of the program.
I tryed to be straight forward, and keep it short. So if you need more info, fell free to ask.

I have made a Database.mdf that contains a table that Includes 3 diffrent Column Names.
1:"ID" This one i set to an primary key and i have also made it automaticlly put a number in order to the list. Like 1,2,3,4,5 for each data added. Data Type for this is int.
2:"WordCombination" Were i enter my word combination that i want it to look for)
3."TypeofCombination" Were i enter what the program should add to what i typed in texbox1 if it contains the WordCombination.
I want my program to se if texbox1 contains any of those WordCombinations in my database. And if thats true, Then i want it to show whats in the TypeofCombination + the text in texbox1 in texbox2. If i enter "What do you want ?" in Textbox1 i want the program to find that "What do you want ?" contains "you want" like in ID:1 WordCombination:you want. So becuse this is ture it should enter TypeofCombination in this case "Question:" + what i entered in Textbox1 to show in Textbox2.So if i write "What do you want ?" and click start. Textbox2 should show "Question: What do you want ?" If i Write "My name is Jake" and click start. Textbox2 should show "Answer: My name is Jake".If I Write "hello you Hi there Jacob" and click start. Textbox2 should show "Greeting: hello you Hi there Jacob".And i Should be able to add and delete Word Combinations Without having to change the program.
