I'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
[code].....
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'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.
I'm currently using the following to code to grab the installed programs and list them in a ListView:
vb.net
Dim SoftwareKey As String = "SOFTWAREMicrosoftWindowsCurrentVersionInstallerUserDataS-1-5-18Products"
Using rk As RegistryKey = Registry.LocalMachine.OpenSubKey(SoftwareKey)
For Each skName In rk.GetSubKeyNames

What I don't understand is when I run the code, I get a NullReferenceException was Handled on this line:
vb.net
If name.ToString <> "" Then
I haven't been able to find much on the error. It seems like it is a pretty generic one and can fit into a lot of different scenarios.

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.

View 1 RepliesI am sure this can be done, as Visual Studio is basically built this way. What I want to do is simply make a class that my other workmates can use.

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 started with VB 6.0 back when i was 14, I was mostly into coding programs that interacted with other programs. Recently I installed VB.net 2005 pro i got from school, and i grabbed few source codes that teach show interaction, I feel so dumb, i dont remember anything lol. It be great if you guys can share some source codes and other stuff in this field. also other day i was in dream spark and i am able to get copy of VS.net 2010 ultimate edition, are there a lot of major changes, cause i got 2 thick book for VB.net 2005..

View 3 RepliesI have a Windows Form Application which has been developed in vb.net 3.5. It is a charting program and shows stock market charts to users. Now I have made another program in vb.net (same .net version) and I want this program to interact with the one I made before. The new program is like a small scripting language. So for example: if I run a script then its output should be reflected in the other program. How can the two programs communicate ? Both will be running on same systems. No remote stuff. I mean passing arrays,strings or possibly structures.
Plus I have several functions which are written in first program. Is it possible for the other program which is an .exe also to call the functions of the other one if I make sub/function public or something. The reason is we can calls functions or subs if we include a dll. But can one exe calls functions/sub of another exe (if both program are in .net).
the only way I can get reading from an instrument is through proprietary software. even though it is connected with USB. the instrument - a Cary 500, with a GPIB interface.the problem is with instrument commands, like "reset" or "change wavelength" or "instrument reading" They reside inside a primitive Basic shell provided by the instrument software. I'm looking at expencive National Instruments, is there another solution with VS/NET?

They are all working on my computer,but they are not working on any other computer(I tested it on about 10 computers). They are working when i start making it,but after they are not working. When i try to run it on other computer it is not opening(there is not any error message), or there is a crash report(application crashes). So they are working on beginning of programming, and after they aren't.
