I have a VB application and I want to allow the user to choose an option between "OK" and "Cancel" buttons when he want to exit the VB application. So far, I cannot figure how to allow the user to click "Cancel" to allow the VB application to continue running. [code] So how do I allow user to click "cancel" button to prevent from exiting?

I validate a DataGridView with the CellValidating-eventhandler.That works fine. However, I want to avoid validating when the user presses the Cancel button. In the sequence validation occurs before the event CancelButton.Clicked.
View 1 RepliesI'm running an application under an account that is not the account logged-on to the PC.
Within the application I need check if the logged-on user is a member of the Administrators group. Below is the code I'm using. From what I've read, WindowsIdentity.GetCurrent() should return an object associated with the logged-on user. It doesn't, it returns the same information as the call to System.Threading.Thread.CurrentPrincipal. Which is the information associated to the ID running the application, not the logged-on user.

Which is the best way to store application and user settings of an application running with multiple instances?My problem is that using the vb's "Application Settings" one instance would overwrite the other one.I want to identify each instance with a number passed via command line argument. I could use this number to identify the appropriate settings of the running instance, but I see in a local INI o XML file a better way to handle that.
View 1 RepliesI have a spellcheck program for an external application. My vb.net app calls a .vbs file to invoke the word spellcheck engine, runs the spellcheck, copies to MS clipboard and then I want it to automatically paste back into the active window. What my issue is, is that I need a delay or check of some sort in the code so that I can know when the vbscript has been completed before pasting text to to the window. I've tried the following but the app invokes the script then immediately checks to see if the script is running (which of course it is) so it's useless... Or is this something I should change/handle in the vbs file? I'm not very good with vbscript however.

I have an application which is running off multiple user desktops (app is in vb.net/vs 2008). The application pulls its data from an SQL 2005 Server (which holds all of the main data tables as well as a bunch of reference tables). So for different projects, the application pulls in data from the main tables... ie, Project ID, Project Cost...and so on.. The data is contained by ID's and when the data is imported into the application, the look up tables are used to convert the ID's to names.. so instead of project ID, the user would see the actual project name. Before the data is written back to the db, it is converted back to ID's ... anyways, there are a bunch of these look up tables, (for vendors, different expenditure codes, projects, sub projects.

I'm using a BackgroundWorker to perform some analysis on a separate thread. The BackgroundWorker is called when a user clicks a CheckBox.
I need to provide for the user clicking the CheckBox, starting the BackgroundWorker task, and then changing their mind and clicking the CheckBox again.I simply want to cancel the currently running task and set the analysis off again. Currently I have the following method:

I have an application which uses hotkeys which are to be defined by the user. It is a combination of 2 keys, either CTRL, ALT, SHIFT as one hotkey and the F* Function keys as the other (e.g. CTRL + F1, ALT + F2 or SHIFT + F8) As stated these are then chosen by the user before a global keyhook is put in place to listen for them and trigger an event. In my app I have all my function keys as follows:
Public Const VK_F1 = &H70
Public Const VK_F2 = &H71
Public Const VK_F3 = &H72

I've used Visual Basic on and off for years, but for some reason this has never crossed my path, though it's probably relatively simple.
I have a program which runs in the background, in the System Tray. (Which is to say it has a NotifyIcon and is Hiding.) Using the Registy, I've added a new item to the right-click menu for certain files (for example PDF) which reads "Accept".
The goal is to have this open the file in my program and have it run the script. The script itself works flawlessly with an Open Dialog box - all it does is change the "comments" on the file. But I can't for the life of me figure out how to do it without the dialog box.
My program requires the reading and writing to a file that is shared among all users of a system. Currently I keep this file (an XML configuration file) in the directory that my application is installed to, which is C:Program FilesSomething by default. On Windows 7 (and probably XP too, but I haven't checked), regular users cannot write to this file. While I could probably set permissions as needed in my installation program, I'd rather find a more appropriate place for this file.All users need to read and write to it. Doing some Googling turns up C:ProgramData for Windows 7, but XP doesn't create this folder. Is there a common place on both platforms? Finally, is there an environment variable I can query for it?
View 2 RepliesI'm trying to create an app to launch at start up that will ask you what applications you want launching, or if you want all your favorite app's to start up etc. But before I go any further, I think its crucial to know how to save settings that a user has entered (such as program location and name in this case) so that he/she doesn't have to enter them every time at start up.
So far I have just made this, can anyone tell me how I would get it to save the settings entered?

View 2 RepliesWhats the most efficient way to read in moderately large data tables of constants? Im talking about maybe a few hundred items in a vector, or some 6 x 6 or 8 x 10 tables of numbers or strings, that kind of thing. (Im aware that they arent really stored in two dimensions.)In the old pre-Windows versions of Basic, wed use READ and DATA statements.In VB, we can read from an external file. I dont like to do this because something might happen to the file.
The resource file is another option. The setup is tricky, but once you get it its simple to maintain. It does involve reading strings and splitting them up to get numbers, which should be slow.Then theres the brute force method, where you just fill in the array in the source, you know,x() = {303, 279, 274, 268,} and so on for many continued lines. Some work to get everything in the right place, but one time only. I suppose that this makes the executable bigger.
