View 10 RepliesI've made a small program that creates a registry item in the users run key (basically starts the program on bootup), my question is does anybody know how to remove the item from all the users of the computer when the program is uninstalled?.
I know that all the other users registry hives aren't loaded at anyone time and feel a custom action dll that runs on uninstall that iterates through the 'documents and settings' folder loading the hives one at a time and removes the registry key.
how can i crate a customized installer/uninstaller package for windows programs?

View 8 Repliesi recently wrote an application in vb.net to print over an a4 paper, the app consists of a basic windows form with a couple of text fields who's values will be printed over specific location on the a4 paper, some of the extra features i added were the ability to save the text in the fields as .pf file (.pf is my own custom made extension name to make this custom extension i had to create 3 keys in the registry: [Code]
This indicates that whenever an application with an extension .pf is double clicked open it with my application and the "%1" means pass in the name of the file as a command line argument to my application (later in my application i added code to deal with command line parameter i.e simply read the content of the file and fill in my text fields with it) also i added a 3rd registry key which describes the location of the icon for this extension: QuoteHKEY_CLASSES_ROOT\PrinterForm\DefaultIcon with a string value of the path to the icon file using the following code: [Code] now i want to delete this keys when the user uninstalls my app. How can i achieve this goal? is it possible to write uninstall code in vb.net?
To create a program that asks for input then uses an else statement to create a handling fee balance.
Input: sales record - first name, last name, purchase amount, balance before purchase
Output: report - full name, old balance, purchase amount, handling fee, new balance
Definitions: handling fee is 5% of the old balance if the old balance is less than $1000.00 else it is 2% new balance = old balance + purchase + handling fee
Processing:
Ask for and receive sales information
Calculate new balance
Print output report
End the program when a purchase amount of 9999.99 is entered

With VB.net, I'm coding a simple application to get more used to the new .Net format.
I'd like to save all the information to a 'new' database file. how to create a database on the fly, once that is done i'll be able to connect to it no problem, but actually creating the file is proving difficult to work/find out.
Also, with vb.net and the newly created custom file, how can it be made to automatically open that information with the program?
Is there a method in installation to associate the file type with the new program? How can i check when the program loads if a database file has been 'double-clicked' (rather than just running from the .exe of the program) and proceed to load the data?
EDIT1 - Extra InfoThe windows application has many different fields and content etc, then i need to save that to a file that could later be loaded by 'double clicking'. I assumed the easiest way would be to create a mini-database for each unique file

Basically, I want it so if dllA doesn't have a method that the application is looking for, it asks dllB. This is assuming, as well, that ApplicationX and dllB don't know anything about dllA and dllA kind of just appeared out of nowhere (I want dlls dynamically like a patch to my applications without having to rewrite ALL of the methods, properties, etc. in the dll and have everything else just routed to the old dll).
As i am trying to create a custom FTP server for an application i've been reading up on this for a while. One part of the problem is obviously the multi threading issue.Now i know that the synclock command will lock an object to the thread that requested it's lock, however in an example on the internet i found the following construction and i am wondering why he would do this.
Code:Private Sub ProcessClient( NewClient As Client )Call SendMessage( "530 Acces Denied", NewClient.ControlSocket) more codeEnd Sub Private Sub SendMessage(ByVal message As String, ByVal ToSocket as Socket)Dim CurrentThread As Thread = Thread.CurrentThread SyncLock CurrentThreadToSocket.Send(Message)End SyncLockEnd Sub Now ProcessClient is a thread that is trying to do some stuff with a newly connected client and SendMessage is just a sub in the same class as where the thread was created. Now normally one would synclock a "syncobject" however here he calls a sub and then from that sub he synclocks to the thread that called it. I wonder what the use of that is and why he does it this way?
I have removed the synclock statement and as I expected it functions exactle the same as it does with it. I tested it with multiple users at the same time trying to connect to it.
I'm trying to create a password change form for my company's vendors. There are a couple of scenarios I could encounter doing this:
1 - User enters invalid current password
2 - New passwords do not match
3 - User's account is locked
4 - User cannot authenticate because password is expired
It's case 4 that I'm struggling with, because their is no way for me to take the password the user entered and verify it against active directory without getting an error.
I've search the net in order to create a custom control but nothing I find is worth looking at, The main thing I want to do is create a skinengin via DLL and import it in my vb 2010 then using or creating some sort of skin builder where I can create a full setting file which contains all the details of the customization regarding the Form(Look, Feel and the controls such as a menu), I have used Iriskin and multiple apps doing this for me and when a user installs my application they still recieve a message about buying the registered DLL file, I would like to create it completely from scratch.
