View 1 RepliesI want to read a string from a registry key, if its 0 do one thing, and if its 1, do something else.
This code (if it works..) would at the first time create a sub key, and assign it to 1, but if its not existing, it would then show a few messageboxe's - But it doesnt work, even if I set it to 1 or 0, it won't work, it always displays the messages.

The setup is running in 32 bit mode and the installer class is made with Visual Basic installer class.
Now the problem is, how to read SQL Server 2008 64 bit registry settings in Windows Server 2008 R2 64bit machine.
E.g. installed instances and the data paths for every instances.

Example code that can be set in visual basic installer class would we nice.

I have the following code to retrieve a string value from the registry.
Dim retval As String = String.Empty
Try
objManagementBaseObject = objManagementClass.GetMethodParameters("GetStringValue")

The problem is that if sValue doesn't exist, it generates a ManagementException. I want those errors ignored because I don't care if the value doesn't exist, it's entirely possible and acceptable. How can I "accept" those errors but display all others?
I'm adding multi-threading facilities for the first time. I have a function that is wrapped to be run in a separated thread. This function retrieves data (text) from a combobox and it works for sure without multi-threading.
When I call it as multi-threaded, I get the following error when I try to retrieve the data from the cmobobox: Cross-thread operation not valid: Control 'cmb1stBL' accessed from a thread other than the thread it was created on.
It looks like a restriction of thread-safety... I assume that the child thread cannot read from his parent, to make sure that he doesn't change his parent data. So how can I read the data from the combobox? Should I read the comoboxbox data before calling the child thread?

Does Anyone know How to read multi-line strings? I am using XmlWriter to write a Multi-Line Textbox to an Xml Document. The Trouble Is I can't figure out how to get the reader to read that multi-line element. I know the writer is writing it in multi-line, but the read just squashes the lines together. Does anyone know how to read that multi-line element properly?

View 1 RepliesI'm working on a way to authenticate users in my app, and what I've come up with is the following method.To write to a database, the user must have an account in SQL server 2008. However, I still want people to be able to view the application if they don't have access, but only read, they can't sync any changes. This is working well, as I have a string array hard coded containing approved users:
Dim Users() As String = {"BWANG", "EDASALLA", "ERICHARDSON", "HALONZO", "JCHAPMAN", "SKIM", "PMACK"}
The one problem with hardcoding is that if I need to ever add a user later on, I'd have to release an update to the program. (which isn't hard as I already have updating built into the app, and users can still download updates even if they can't sync.)
What I'd like to do, is use an encrypted .dat file that contains the user names, and store that with the application, so that i could always be added to, and only one file would need to be downloaded.
I have code in place to encrpt and decrypt the .dat file (called users.dat) and this code works for single text entries in the file. I need to figure out how to load a list however into the array in place.
Imports System
Imports System.IO
Dim userfile as String = "C:users.dat"
Dim Users() As String = Data.Decrypt(File.ReadAllLines(path))
Basically each line in the file will have an encrypted user name, and i want it to decrypt each line and store it back into that authorized user list.

How do I read, write and delete a registry using VB 2005/2008?
View 1 RepliesI'm having troubles reading the values from a registy key, basically I already have my code working which reads back data from a registry key with the name "Printer" however I also have another key called "Printer" and when I attempt to read that the "+" get ignored and it reads back "data" which is in the same location. Is there a simple way of reading it back which won't mean large changes to code that is already working as I need it to?

[code]After spending hours of research.I finally figured out the vb.net version on how to read a 64 bit registry with a 32 bit .net application. The importance of this is when you try to write to one part of the registry, it gets redirected somewhere else in the registry, which is super annoying.[code]

I'm reading the registry values under the uninstall registry keys. I use string variables to store the program name and program version. This usually works fine but for example Firefox 10.0 appears to be less the Firefox 9 since the version is a string value.
