Making an app OS dependant

[mstester]

Hey Guys,

I want to make an application (in VB.net or c#) which will run only on a Server 2003 box, does anyone know of a way to do this?

Thanks,

Why not just get the program to look for the OS String... and then if it doesn't equal that it just says "nope, go away" lol

Something like this should be helpful for C#:

[LLXX]

The GetVersionEx function obtains extended information about the version of the operating system that is currently running.

BOOL GetVersionEx(

LPOSVERSIONINFO lpVersionInformation // pointer to version information structure

);

Parameters

lpVersionInformation

Pointer to an OSVERSIONINFO data structure that the function fills with operating system version information.

Before calling the GetVersionEx function, set the dwOSVersionInfoSize member of the OSVERSIONINFO data structure to sizeof(OSVERSIONINFO).

Return Values

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError. The function fails if you specify an invalid value for the dwOSVersionInfoSize member of the OSVERSIONINFO structure.

Remarks

The GetVersionEx function supersedes the GetVersion function and is the preferred method for obtaining operating system version number information. New applications should use the GetVersionEx function rather than the GetVersion function.

There you go.

hey guys cheers for the help on this, still not sure what direction to take, i was recently pointed at this piece of code which works fine

Public Function OS_Version() As String

		Dim osInfo As OperatingSystem
		Dim sAns As String

		osInfo = System.Environment.OSVersion

		With osInfo
			Select Case .Platform
				Case .Platform.Win32Windows
					Select Case (.Version.Minor)
						Case 0
							sAns = "Windows 95"
						Case 10
							If .Version.Revision.ToString() = "2222A" Then
								sAns = "Windows 98 Second Edition"
							Else
								sAns = "Windows 98"
							End If
						Case 90
							sAns = "Windows Me"
					End Select
				Case .Platform.Win32NT
					Select Case (.Version.Major)
						Case 3
							sAns = "Windows NT 3.51"
						Case 4
							sAns = "Windows NT 4.0"
						Case 5
							If .Version.Minor = 0 Then
								sAns = "Windows 2000"
							ElseIf .Version.Minor = 1 Then
								sAns = "Windows XP"
							ElseIf .Version.Minor = 2 Then
								sAns = "Windows Server 2003"
							Else 'Future version maybe update
								 'as needed
								sAns = "Unknown Windows Version"
							End If
					End Select

			End Select
		End With

		Return sAns
	End Function

However im unsure of the following bits?

If .Version.Revision.ToString() = "2222A" Then

??? any ideas

Thanks crahak for clearing that up for me, just a thought though. Would it be possible to make an .msi which would check to see what version the OS is and if its not 2003 kill the installer? would this be more efficant than having the application check the OS?

Gee. Thanks Yzöwl...

At least on newsgroups, there isn't one single person with god-like powers that can nuke your entire post if they feel like it over a slight difference of personal opinion about one sentence in it. They don't usually side with the trolls either.

No point in posting your section seemingly. Won't be making the error of wasting time on that anymore. I've edited all my posts in the section to reflect that.

That's nowhere close to a "solution". You're suggesting he should bypass the [very bloated] standard .NET classes

Fixed.

Wait a moment... this is .NET so I should just get out before I start getting influenced~!

[Yzöwl]

Okay, I'm all for healthy debate!

Unfortunately crahak's latest post was a little bit beyond what I would term healthy and has as such been removed.

If you must fight, please keep it a clean.

Thank you.

lol sorry to have caused a fight :s

Anyways I was thinking instead of using the app to determin wheather or not its OS 'x' should I get the msi to do this, is this even possible or am I talking through my noobie hat?

[LLXX]

Yes, a versioncheck can be done with the MSI.

See the (freely downloadable) MSI SDK documentation for more information.
