Sorry for the extra long title, Here's what I want to do.I want to give the user the option of using or not using specific features of the program.If I can set a simple yes or no value that wil persist each time the program run and then depending on the variable turn off or on the feature at start
View 14 RepliesI want to hear some discussion regarding what is the best way to persist program parameter and variable settings from one run of the program to the next. I used to often use the ubiquitous INI type file in VB6 programs but I am aware that these are not formally supported in .Net programs. I also have a major aversion to adding to the already overwhelming bloat of the Windows registry by using that to store values.

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 3 RepliesI'm looking for a more elegant way to work around a problem I have
Code:
Private Sub MnuCheckForUpdates_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MnuCheckForUpdates.Click
Dim startInfo As New ProcessStartInfo(mStartUpPath & "" & "Updater.exe")
Process.Start(startInfo)
End Sub
As you can see I�m calling my updater program, but I want some code to run only after the Updater has closed.My work around was to:
A - Initially load the updater.
B � Start a time
C � Check if the updater is still running.
D � If its not call the routine in the timer event.
But this is not elegant is there another way around this, I can call events in the updater but I don�t think I can join them in someway to ProcessStartInfo Class .
I have made a program that has an intro screen, moving onto an activity select screen which acts as the main interface to get around the program. After creating the program and installing it on my computer, when I close the program from the activity select screen, using the "X" at the top right corner, the program continues to run under "processes" in the task manager.If I close the program from the intro screen though, it will close everything, including the processes. Is there anyway I can get the same to happen with the game select screen? I can make it work by putting my own "End" button on the form, but id prefer to be able to do it with forms own close button.
View 5 RepliesI'm working on program that has two forms. The main form is called 'frmMain'. Second form is called 'FrmHistory'. In the History form, you can check a number of combo boxes to set settings for a grid.
This works.Now, when I close the FrmHistory form and then open it again, I have it so those combo boxes (Settings) are how I left them. This works. I do so via this.

i have a third party software and i would like it to lunch when someone runs my program (and no its not a virus). But the thing is when you run it; it shows up in the system tray, how can i set the program to invisible and close it when it my app closes?
View 13 RepliesOk, So I am making a front-end for a program, and it runs the exe with command line arguments. One of those arguments is creating a log file that tells me who the winner is. Currently I have code that runs the app, tell VB when it exits and then does another event. When testing with message box as the other event, works fine.
When running the System.IO.Streamreader the app just closes down on its own and there are no errors shown.

View 1 RepliesDoes anybody know if it's possible to make your program 'self-destruct' (delete itself) when it closes? I know this sounds like malware, but it's not. What happens is the user clicks 'install', the application copies itself to another directory, then the application starts the new copied file, with an argument that begins the installation, kills itself, and then the copied application restarts and then it's done. But I can't get rid of the original executable.

View 1 RepliesI have a VB program that displays a PDF file. When the program is closed it takes 30 seconds or so before AcroRd32 process releases the PDF file. In certain circumstances if the program is restarted with in this period, the PDF file does not display. The specific circumstances is that I have a second program (re)starting the program that displays the PDF file.
a) Make the PDF file be immediately released when my program closes
b) When the PDF file is loaded test that it properly loaded so that it can be reloaded if necessary.

The variables in the brackets [example] do not actually have brackets in them in the original code. These are where the issues are. For both variables, it says, "The type for variable [variable] will not be inferred because it is bound to a field in an enclosing scope. Either change the name of [variable], or use the fully qualified name (for example, 'Me.[variable]' or 'MyBase.[variable]')." Now, I'm not entirely sure if this is a stupid question or not, as I'm used to VB '98 because that's what we use in my programming class at High School. let me know why this won't work.
-Note: The intention of this program is to continually loop the generation of numbers for this list until I tell it to stop.

The above code is what I used in VB6 to close all forms associated with my programs before my program closed. I have been searching for information on how to make sure all forms are closed when closing a VB2008 program.
I have seen info on using the Project Property Shutdown mode When startup form closes and I currently have this set.
Is this all that is really necessary? Will the garbage disposal close everything else to free up RAM?
Also, if I have several forms open and want to close all from the main form without closing each one individually, what is the best approach? Is there a collection like in VB6, go through the collection, compare it to the name of the main form and close it if it is not the main form?

I'm working with Visual Basic 2008 Express. My application opens with the Terms screen, a form that asks the user to declare his acceptance of certain terms and conditions or to decline. If he accepts, the app opens the main screen, giving him access to all the app's facilities. If he declines, the app gives him a message and then closes. Whether he chooses to accept or decline, the app puts his decision in My.Settings so that it can be used next time the app is opened. In this way he is presented with the Terms screen on the next opening if he declined on the last run. But if he accepted on the last run, he is presented with the main screen on his next opening.
All works fine when I do a debug run. But when I build and publish the app onto my desktop it opens with the Main screen instead of the Terms screen.
why it works on F5 but not after publishing?

I need to very quickly write an exe system on a laptop where when the laptops are connected to the network they read a database table and store the data locally, so staff can use the laptop while they roam.The laptops have quite small capacity and the company would prefer not to use SQL Express or Access.
My question is, can the data initially be downloaded into the exe application via a dataadapter and dataset, and will that dataset the retain the downloaded data, or will I need to ensure the dataset is written to an XML file and then loaded/unloaded each time the laptop application is started while the staff are travelling ?
