The last thing that is bugging me and hopefully I will pronounce this project finished after this. I have code to get all the software installed on the machine. Its all working however I have noticed if I open Control Panel and Programs and Features not all the software listed there is picked up in my software.
View 9 RepliesI'm trying to find a way to get all of the programs that are installed by accessing the information from the registry. I googled it and was able to find the following code
Private Function Getinstalledsoftware() As String
'Declare the string to hold the list:
Dim Software As String = Nothing

I have been trying for days now how to create a process to the user to easily create a connection to any installed data types they have installed. I have found an example right inside vb2008. I never use this because I code my own connections, but this would be real nice if I could include it or duplicate it.
View 1 RepliesAll I am trying to do is write a simple program that will let me choose a directory and get a listing of all files in that directory and its sub-directories and show it in a RichTextBox. I got as far as being able to select the directory but when I click "OK" I get "access to c:documents and settingsstevedesktopmp3 is denied".The code I am using is listed below.

how would i go over an external directory listing (like an external computer that i am connected to through winsock or likewise) with a server and client..i would like to hear some suggestions on what libraries to use also (winsock, unolib,...)I need this for a school assignment so help is more than welcome. I'm planning on letting the client download files from the server through this directory listing or something likewise..it doesn't matter really if it's a directory listing or something else, it just has to be user-friendly.

I'm almost sure that I've seen this somewhere, but I can't find it anymore. Or maybe I'm imagining it, which would'nt be strange either.
When creating a sub or function and adding parameters used when calling it.
-Is it possible to list the parameters that I can enter when using it somewhere in my code?
E.g.
Public Sub MessageMain(ByVal Message As String, ByVal MessageType As String (List of possible values for MessageType)) Same for example as when you have boolean values in a sub/function. As soon as you use that somewhere in your code intellisense will present you with True/False to select.
I'd like the same for parameters in subs or functions I create and calling them from somewhere in my code. Saves me the trouble of remembering which options are available for those parameters.
I recently installed vb express 2008 and with that download i also installed Sql server 2008. Earlier i have been working in MS Access so i have no experience in SQL server. My first problem is how to start sql server. I can see only following:

I would like to know where the dataset designer is obtained for a vb.net 2008 appliocation I need to work on. Is this part of the initial install for visual studio.net 2008. If so, what part of the initial install will I find the dataset designer? Is this a plugin that needs to be downloaded? if so, what URL do I need to use to obtain the plugin?

I'd like to mention that getting a list of the installed programs via the registry is not a viable way to receive a full an accurate list. The two main areas where the programs in the registry are stored, are mainly MS programs. Some manufacturers put their keys here as well, but most don't. And since it's impossible to know where the manufacturer has stored the key, let alone the name of the key that would give the list and the uninstall capability, it's not ideal to use the registry.
That being said, I was told that there is a COM API that Microsoft has made and uses in the Windows OS and was hoping someone knew what that API is and how to maybe implement it in VB.

View 2 RepliesI'm just starting out with VB and have downloaded and installed VB Express 2008. I'm researching and trying to wrap my head around programming in VB before I start working on any projects. I have a little bit of experience with ASP Classic so some of the syntax looks familiar, but I can't get a handle on database integration. Let's say I am creating an address book. Each installation is a stand-alone (no network connectivity). How are databases used in this situation? Are they built using VB Express and packaged into the installer or can you create them separately (using either Access or MySQL) and then package them into the installer? What is needed to read and write to these databases? Are there extra bits of software that need to be packaged into the installer to allow access to the databases?
What if this application does connect to a centralized database (let's say a MySQL or Access database on a web server). Is the connectivity handled the same way? Sorry for so many questions, but I just can find the answers I'm looking for when searching. I'm not necessarily looking for the actual code to do this, just an explanation of how it's possible (or even a link to some examples/tutorials).

View 3 RepliesI am trying to deploy an application that uses SMO on a workstation without SQL Server installed on it. The instance the app is connecting to is SQL Server 2008.
