I've been looking around the internet and I haven't really found any solution to my problem. Is there a way to perform a function when a user closes the form either by pressing the X button in the top right hand corner? I am using a database that saves what form the user is currently looking at, and when the application is closed I want to say "offline."

View 6 RepliesI have aconsole application that executes 2 other processes, and then closes the processes once it's finished its work.
If the user closes the console application prematurely, the 2 other processes go rogue and sit idle (As they are expecting to be closed by the console).
Is it possible to detect when the user clicks the X or closes the console app in another fashion, so I can also destroy the spawned processes?
I have a small problem with sockets (I'm new to sockets). Below is the code I'm using. The problem is that when the client closes, the server closes aswell. How do I stop it from doing that?

I created an app and what it does is takes a screenshot of your desktop, saves it, then uploads it to ftp. After that it closes. What i need it to do is continuously do that via what ever the interval is set to. So if the timer1 interval is at 12000 then i need to to take a screenshot and upload it every 12 seconds. Can someone tell me why is keeps closing after it uploads the 1st screenshot? [code]...
View 3 RepliesI have a problem here I hope someone can help me out. I have this application in which I show information about workplans. It has a Main Form which show the general information and the activites that are going to take place during the execution.
The application has the ability to "attach" documents to the activities. I have created another form (and MDI form) that I use to show the documents (pdfs) when a user clicks on one of the documents attached. The problem is that when I close the form that shows the documents, it ends the application and I don't know why. It should just close and leave me again with the Main Form. Can someone tell me why is this form terminating the app. Is it because is MDI or what?
I want to retain a value in a variable even after the application closes so the next time i open the application i can get that value.It's actually an integer value, i want to count the no. of times the application has been opened. I tried using static [b] but it doesnt work.
View 8 RepliesI need to update a table when my application closes. This is with the user name of the person exiting the app.
This works fine when the user closes the form from the main menu exit button where I have written code to update the table. However if a user exits from another form the main form is not closed (as I thought it would be) and the code that updates the table consequently does not run.
I have tried entering on other forms under the FormClosing event but this does not seem to run if they click the X in the corner of the form.
How can I get that code to run when a user exits in some other way.
I've made a Windows Forms Application that runs fine. It has some buttons that open child forms, which can simply close again without any problem. As I need the form to be in a dll, I changed the application type to a class library and added an extra project containing an exe-file that only references the main form in the dll and shows it. So far so good...
The main form is basically a tabcontrol with a bunch of controls, buttons among others. Five buttons on different tabs use the same handler to open a child form. When I click the button on the first tab everything works fine. The form opens and when it closes, only the child closes. When I click any of the buttons on the other tabs, the child form opens and when it closes again, both the child and the main form close...
I am stumped, especially since all buttons use the same code to open the child form and everything appears to be completely identical, yet the results are not. Below I have pasted the code that opens the main and child forms. I am undoubtedly not looking in the right place, but I also have no idea where to look anymore, let alone what to look for...
The code opening the main form:
Public Sub StartProgram()
'Load the form and show it
Dim frmProgram As frmMain = New frmMain

View 3 RepliesI ran out of ideas and couldn't find any reference about it so here I go... I need to keep a secondary application wich is not related to my c# project always running in background. So if this secondary application crashes or someone else close it manually it will automatically re launch again via my c# app.
I have no clue of how to accomplish this one, I mean checking if this application closes by something external to my c# app.
Is there an easy way to disable all form validation when the user clicks on the "X" icon to close an application or when the user clicks on a button in the application that closes the application?[url]...
View 1 RepliesI have a parent form and a few subforms. When the user clicks the red X to close the form I have a dialog box open that asks the user if he wants to exit the application. I have a issue when the user clicks no the application closes anyway. I am wondering what I am doing wrong. [Code]
View 8 Repliesdetect whether the current application is a console or a winforms application.The reason that I want to do this is that I am developing a library with a global error handler in it and I need to know what type of application it is in order to be able to subscribe to the appropriate exception event.Obviously I could get the user to pass in a parameter specifying what type of application it is, but I would rather deal with that automatically so its all encapsulated from the user of the class.
View 1 RepliesI want to ask the user a barrage of questions regarding configuration settings within the application. All that is handled, except that I want to ask them on the first run. (Kind of like a "Welcome form".) My question is, what is the easiest way to detect the first run and how would I go about doing so? Side note: regarding the link above, which location would be a good location to set a key value? (I've never really worked with the registry much until now.)

View 1 RepliesI have a WinForm program developed in VB.Net with Visual Studio 2005. The program needs Microsoft Office Runtime installed atleast on the computer to allow the application to run without any errors.
Is their a way to check the computer to see if the minimum of the Runtime or Microsoft Office is installed on the computer? If either isn't I would like to display a message to the user on the startup of the application that states to atleast go to Microsot's site (I have full link to Runtime Download) and download the runtime for free.
Or is their a way to include the runtime as a component with my install for the application so if it isn't installed on the computer already it will install when the application is installed?

View 2 RepliesI spent some time with data modems till I realized it's a voice modem that I'm going to need in my application. I see that there are some other commands for a voice modem, although nothing very elaborate. I would imagine you make the call as you would in a data modem ATDT etc and it looks like there is really just one command to send audio...
AT+VTX
AT#VTX
Not sure what this is all about except maybe just different standards? Still not sure about how to detect when the call is answered though. I won't be talking to another modem. Maybe the serial port itself has a pin change or something? You would think there would be a bit "somewhere" that the modem would generate when it quits ringing. I may have build my own outboard box to do this. (easy enough -- probably more reliable too -- modems sure need rebooting a lot it seems).
Here is the goal though --Voice modem calls out, call is answered, and I inject my audio from the PC sound card for a minute or so and then tell the modem to hangup.
I am in process to develop an application for Windows Mobile 6.5 using Visual Basic 2005 and .NET Compact Framework. My problem is that I want to know if an instance of my application is already running and, in that case, I want to jump directly to that instance, without starting another one. I tried several solutions found on the internet but I think there are solution for desktop applications not for mobile applications because I have a lot of errors.
