Is there an easy way to get a list of the installed web browsers on the system (including the path to their respective .exe)? I have a web application which uses the Web Browser Control, but I would like to give the user the ability to view their web page in any of their other installed browsers.

View 3 RepliesI have a dll installed on my machine and want to find a way to verify this programatically with VB.Net. I have been trying to use LoadLibrary but it always returns a zero. Can someone provide a code snippet of how I might do this?
Also, if there is another way to verify that a dll is installed, without having to supply a full path, please let me know.
I have to access the active x dll which is installed on my system from VB.net.
I added as reference and followed all the steps as given in I have declared private mycomponent as activexcomponent.libclass and i gave constructor for this i.e. creating the object for this class in the constructor of the main form as mycomponet = new activexcomponent.libclass()
Then the following expection is coming when i tried to run the program.
System.InvalidOperationException: An
error occurred creating the form. See
Exception.InnerException for details.

I am writing a application where i need to know which games are installed on a system.I have 3 ways by which i think i can detect the games
1: Scan specific parts of registry and look for key names that match with a List of Publishers. The list is manually maintained.
2: Scan the hard disk for and do same as in step 1
3: run the program in background and check for programs in memory that use a large portion of memory(which games always do) and if they use Direct X ( Which all games do except for some) then its a game.
Now i have been thinking about it and first and second method seems to be in need of a updated database ie list of publishers to make out if a particular program is game.
I am having trouble developing an asp.net page. I can create custom collections and use them in win apps, but when i reference the system.collections namespace, the page response hangs up. No exception info is passed back or anything. The page just freezes. Is this a common problem. I am wondering if its due to the assembly not being present (but am unsure why an exception wouldn't indicate this.).

View 2 Replieshow can i view my installed program list and uninstall program from the list using vb.net 2008.
View 1 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.

View 1 RepliesI am trying to create a plugin system. I have the actual plugins working fine but now I want to implement a system that knows whether the plugin is installed or not. I can get the plugin name when the form is loaded (ex. "Plugin1"). I then want to check this against something to see if that specific plugin is already there (if not add it) and if it is there is it enabled. I was thinking of doing this with an xml file but thought that might be a lot of work reading and writing each value. I then thought of the My.Settings and was wondering if this is possible. I would want to create an "element" for the name and give it a value of either true or false.

Question: How do I programmatically determine which provider to use (Microsoft.Jet.OLEDB.4.0 vs Microsoft.ACE.OLEDB.12.0) when my app runs as a 32-bit process on a machine with Office x64 installed?
I'm developing a VB.net WinForms app in VS 2010 and targeting both x86 and x64.The app processes data from xls, xlsx, mdb and accdb files using System.Data.OleDb:Dim oConn As OleDbConnection = New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=...")
The x64 version of the program works as expected. The x86 version works as expected on a system with Office x86.When I run the x86 version on a machine with Office 2010 x64, I get the following exception when trying to open a connection:
The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine.I believe this is because I'm running Office 2010 x64 so the x86 data access components are not installed.I can get it to work for Office 2003 files (*.mdb and *.xls) by changing the provider to Microsoft.Jet.OLEDB.4.0.
How do I figure out which provider to use when running as a 32-bit process on a machine with Office x64 installed?Ideally, I'd like a function:If ProviderIsAvailableFor("Microsoft.ACE.OLEDB.12.0") Then
Else If ProviderIsAvailableFor("Microsoft.JET.OLEDB.4.0") Then
