can anyone give me a sample on how to make in vb.net a Dialup Network Connection (DUN) i tried google, it gives me RASDialer w/c is kinda >.< basically.what i wanted to implement first is to detect Modems... coz we have a 3G sticks here where we can connect to the net. after detecting the modem. then it will dial it. even without having the panel or dashboard of our modem stick.
View 1 RepliesI have a modem that CLAIMS to be voice, i still can not get it to do what I want.
1) The modem dials and makes my phone ring, when I pick it up the program does not reconize the event. I have to physically click on button that says Talk. Then my CallStateChanged fires.
2)My other issue is that I can not get any sound to come over the line. I essentially have a wav file that play nicelys on the computer but the modem is not picking it up. Is there some way that I can test the modem to be voice?

It was necessary some extra code for establish communication?

View 2 RepliesI have a webapp where a datagridview is populated with records from a database and one of the columns is a download link to download the zip or exe file. We have the zip files on our server, but not the exe files as those are on another department's server. We have all of the file available for download, but if the user as an option selected in a dropdown, those url's in the gridview are re-formatted to be the exe file's on the other dept's server, however they don't have all of them (some 20% are missing) which means if the user click's the link they get their server's 404 not found page and can't download the file.
My PM (Project Manager) is asking me if I can have our webapp detect that the file doesn't exist on their server and instead of them getting the 404 page, they don't leave our app at all and get a javascript popup window or the page is refreshed with a red mark (and a message) next to the link they clicked on, is something like that possible? I have 2 restrictions with this, I can't modify the database because it doesn't contain file paths, it only contains a small portion like (Clinton County, Eaton County, Traverse County, etc..) and the rest of the url is formatted on the fly when the page is rendered, so there's no way to mark the missing files and there's no way we can host the files.
I am using a richtextbox control on my form.I want a small code which can detect if any image has been inserted in the rtb or not.For e.g. user can just type some text or insert image also. Now if we select an image then we can get the type but I want a code which scans contents of rtb and gives me a true if an image is inserted or false if there is none.
View 8 RepliesI have roughly 20 text boxes on my form,When you press tab, it naturally selects all text in the box (highlighted in blue), so you can press any key, and it replaces it with that,That result is what I want, unfortunately, if you click into the text box, and tab back to it, it no longer selects all the text.I'm wondering how I can detect the tab event properly,I've tried adding a 'KeyDown' event to each text box, and then selecting the text, but the sub never runs, also tried detecting the tab event in my Main Form, thinking that perhaps the parent handles it and will receive that event, but.. No.I've thought of using an event like 'Activated' however, it will also run when the mouse is clicked.

View 10 RepliesI'm writing a program and it's got a textbox for the user to enter values. Since the textbox text property should only be a "number", my program need to detect invalid charaters like "*/&()$" and tell the user to only enter a number. Does anyone have an idea how to do that?
View 6 RepliesAdding How would you detect if the user is using the computer? I want a program to detect if the user is using the computer (i.e. mouse and keyboard movements), and if the user doesn't type or move the mouse for a specific amount of time, it executes a command. Normally I would do this with the Application.Idle, but I want it to be detected throughout the system. Any starters?
View 22 Repliesi have a two-dimensional char array that holds the values of a tictactoe board.Each element holds a value of either 'X','O', or and you can access the values with something like TicTacToe[0][1]with the first bracket containing the row # and the second containing the column #.
Whats the best way to detect the winner of a TicTacToe game? I was thinking about just making a function like this Private Function checkWin(Byval TicBoard as Char[][]) as Integer 'Return 0 if no winner, 1 if Player 1 wins, and 2 if Player 2 wins End Function Any ideas? I want to avoid using 8 if-else statements since that seems pretty inefficient and sloppy
In our program we track the moves in arrays by columns 0 means empty, 1 means black, 2 means red so it would look like this for example
column1(0) = "1"
column1(1) = "2"
column1(2) = "2"
column1(3) = "1"
column1(4) = "0"
column1(5) = "0"
for column 1, and we have seperate arrays for each column (7 in all) but they all have the same values 0,1, or 2 so how can we make it check the arrays and their values and detect a winner?

I am developing a parental control application containing a feature that logs a user off of the computer after an administratively set period of time. I do not however want the application to continue counting time against the time limit when the user is not active on the computer. EXAMPLE: Child logs on and is active for an hour then leaves computer for 45 minutes to get dinner. The session timer needs to ignore the 45 minutes of inactivity. I have thought of two ways to accomplish this.
1) Use a SystemEvents.SessionSwith event (to detect the Start Menu > Log Off > SwitchUser action), or
2) Use an event which would detect user inactivity in excess of a set time, e.g. 5 minutes (similar to a screensaver).
Either event would call a method which would simulate a pause feature (as StopWatch and Timer have no pause support that I know of). I believe the 2nd option would prove to be more universally affective as 1) some users do not have Fast User Switching enabled, and 2) users would be required to manually switch users in order to prevent their inactive time from counting against them. My problem arises when I attempt to implement one of these methods. According to the IntelliSense error checking engine, I have absolutely no clue how to do either of these tasks in spite of the research I have conducted on the topic. I would prefer to go with the system idle time approach.
