Retrieving data from GetUserObjectInformation to VB.net Andy Henderson2-Aug-04 8:16 Andy Henderson 2-Aug-04 8:16  From various sources I believe the declaration should be... Declare Function GetUserObjectInformation Lib "User32" Alias "GetUserObjectInformationA" (ByVal hObj As Integer, ByVal nIndex As Integer, ByRef pvInfo As Object, ByVal nLength As Integer, ByRef lpnLengthNeeded As Integer) As Integer However, I keep getting 'Specified OLE variant is invalid' when I try to call the routine. I've found various samples for using this call from C and even one from VB but none from VB.net. Does anyone know how I should be picking up the pvInfo parameter? Here's what I'm doing now... Dim InputDesktopName(256) As Byte Dim InputDesktopNameLength As Integer Dim UOI_Name As Integer = 2 Dim x As Integer ... x = OpenInputDesktop(0, False, 0) GetUserObjectInformation(x, UOI_Name, InputDesktopName(0), 256, InputDesktopNameLength) It's returning InputDeskTopLength OK so I'm pretty sure I've got the pvInfo parameter wrong. Andy Henderson Re: Retrieving data from GetUserObjectInformation to VB.net Andy Henderson3-Aug-04 8:10 Andy Henderson 3-Aug-04 8:10  Got it! the Declare statement should use "ByRef pvInfo As Byte" instead of "ByRef pvInfo As Object" Andy Testing ASP.NET WebForms kavithasomaraj2-Aug-04 7:47 kavithasomaraj 2-Aug-04 7:47  I need a favour from you. I am desperately hunting for a job and I have an interview for a post in .NET Software testing. I have knowledge of .NET. Now this testing is new to me. For the past two days I'm doing a lot of study on the same and now I have little knowledge of Black box/White box/Unit/Mock Testing and TDD etc. I have also downloaded NUnitASp testing tool, but unluckily it is'nt working on Web Matrix and I don't have VS.NET. Anyway I'm able to follow the coding. Can u please give me more details on Testing on the .NET framework especially Smoke Testing, Integration testing, Component Testing etc. and also most importantly I want to know if this testing process is all automatic or do u need to do coding when it comes to large software development companies. Will it be difficult for me to follow things as I have only done three small projects on .NET on my own. Do reply to rajupi@hotmail.com & do treat this as urgent Regards, Kavitha .NET IE Addins Padgett Rowell1-Aug-04 5:56 Padgett Rowell 1-Aug-04 5:56  Hello, Does anyone have any idea how to (or if it's even possible) write a toolbar add in for internet explorer using C# or VB.NET? I have found several examples / documentation in C++, which I don't know well enough to play with. Any advice would be greatly appreciated. Cheers, padgett Ps. Yes this is a cross post[^], but I didn't get much of a response so though I would ask in a different forum.

I would suggest you read the following: Command Prompt Explorer Bar[^]. There is quite a bit of COM Interop as well as P/Invoke that allows this to work but this should get you started. - Nick Parker My Blog | My Articles Re: .NET IE Addins Padgett Rowell2-Aug-04 18:47 Padgett Rowell 2-Aug-04 18:47  The article is light on documentaion but at least I now know it can be done and have a good starting point.

When i start my computer on booting it shows the message Box '.NET Framework Initialization Error C:\Windows\Microsoft.NET\Framework\v1.1.4322\mscorwks.dll could not be loaded.' and some of the programs on execution gives this error. I have Windows XP Professional edition. Initially in my system mscorwks.dll is present in C:\Windows\Microsoft.NET\Framework\v1.0.3705\ but i copied it to the C:\Windows\Microsoft.NET\Framework\v1.1.4322\ but then also it gives the same error Please let me know how to fix this problem Any pointers and help is appreciated. Naveen Naveen Re: Dll could not be loaded Roger Wright31-Jul-04 4:53 Roger Wright 31-Jul-04 4:53  Copying the wrong version of the dll (the one in \v1.0.3705\ is from the v1.0 release, not the current v1.1 Framework) won't work. Reinstall the .Net Framework 1.1 and you may find that the problem goes away.

"My kid was Inmate of the Month at Adobe Mountain Juvenile Corrections Center" - Bumper Sticker in Bullhead City Fun with compiler errors adonisv30-Jul-04 8:22 adonisv 30-Jul-04 8:22  I'm getting these errors as I try to upgrade an visual studio 6.0 project to .NET. 1)"error C2628: 'wchar_t' followed by 'unsigned' is illegal (did you forget a ';'?)" which points to this part of the code typedef wchar_t WCHAR; // wc, 16-bit UNICODE character in the "c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\PlatformSDK\Include\WinNT.h" file 2) "error C2371: 'BOOLEAN' : redefinition; different basic types." which points to this part of the code typedef BYTE BOOLEAN; in the "c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\PlatformSDK\Include\WinNT.h file." and last but NOT least, 3) "error C2371: 'BOOLEAN' : redefinition; different basic types." which points to this part of the code /* For backward compatibility */ typedef VARIANT_BOOL _VARIANT_BOOL; #else /* ANSI C/C++ reserve bool as keyword */ #define _VARIANT_BOOL /##/ #endif typedef boolean BOOLEAN; in the "c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\PlatformSDK\Include\WTypes.h file." Is there a way to NOT include these files when I compile? Re: Fun with compiler errors Eric Reynolds4-Aug-04 5:04 Eric Reynolds 4-Aug-04 5:04  There's an easy way to stop WTypes.h not being included and that is to #define __wtypes_h__ at the beginning of your source file, or even just add __wtypes_h__ as a defined macro in your project settings. This may well not solve your problems, however. Re: Fun with compiler errors adonisv4-Aug-04 17:20 adonisv 4-Aug-04 17:20  Ok I'll try that thanks... Re: Fun with compiler errors adonisv11-Aug-04 11:59 adonisv 11-Aug-04 11:59  That actually gave me more errors. Where would you suggest putting this macro in the project settings? Under which tab?? I dont get this compiler setting conflict! adonisv30-Jul-04 7:16 adonisv 30-Jul-04 7:16  These are my settings in Project, Properties, C++, Command Line. /Od /AI ".\..\Bin" /D "WIN32" /D "_DEBUG" /D "_WINDOWS" /D "_AFXDLL" /D "_MBCS" /FD /EHsc /RTCs /MDd /GS /Yu"stdafx.h" /Fp".\Debug/AdoManRs.pch" /Fo".\Debug/" /Fd".\Debug/" /W3 /nologo /c /Zi /clr /TP But I keep gettting the error that /RTC1 and /clr are incompatible. cl : Command line error D2016 : '/RTC1' and '/clr' command-line options are incompatible I don't see that those two options are being used. I've tried every combination of compiler options but I just get the same error. Re: I dont get this compiler setting conflict! leppie30-Jul-04 8:06 leppie 30-Jul-04 8:06  /clr is activate via the "use managed extensions" option in the general page. /RTCx is enabled via C++/Code Generation/Basic Runtime checks. Looking up the Compiler error code will should give a better explaination too.

New features in .net 2 beta SirErugor30-Jul-04 5:22 SirErugor 30-Jul-04 5:22  Salutations mateys.... I was wondering about the new features in .net framework 2 beta.. Can anyone tell me or give me a list of the new features? Thank you in advance Morten Kristensen aka. Sir Erugor Re: New features in .net 2 beta leppie30-Jul-04 7:52 leppie 30-Jul-04 7:52  This is good starting point, I dont see much info now, but im sure it will fill up. http://msdn.microsoft.com/netframework/downloads/updates/fw20readme.aspx[^] top secret xacc-ide 0.0.1 Processing after suspend or hibernate Andy Henderson30-Jul-04 3:35 Andy Henderson 30-Jul-04 3:35  In W2K and XP, when you resume after a suspend or hibernate the OS asks you to provide a user id and password. While this is happening, the suspended programs continue to run in the background. Does anyone know how to detect this is happening from within the program? I'd like to suspend processing in my program until the user has logged on. Andy Re: Processing after suspend or hibernate leppie30-Jul-04 8:11 leppie 30-Jul-04 8:11  Enviroment.UserInteractive , mite be of help. top secret xacc-ide 0.0.1 Re: Processing after suspend or hibernate Andy Henderson31-Jul-04 23:55 Andy Henderson 31-Jul-04 23:55  Thanks for the suggestion, but that is specific to services. For ordinary programs running on the desktop it always returns 'True'. I ran a test just to be sure. Thanks anyway, Andy Re: Processing after suspend or hibernate leppie2-Aug-04 1:20 leppie 2-Aug-04 1:20  Andy Henderson wrote: is specific to services. Oops didnt know that Will add to my knowledge base! Another suggestion, you can perhaps look if a handle has been created, that failing query the size of the form, if size.empty normally the program is in a minimized state, but u could check for that, it mite be diffenrent in your case. top secret xacc-ide 0.0.1 Re: Processing after suspend or hibernate Andy Henderson2-Aug-04 3:37 Andy Henderson 2-Aug-04 3:37  Thanks again for the suggestion, but no good either. The program runs in what it thinks is a normal environment - it even has a current user even though a log in screen is being displayed! I guess there might be some kind of system message, but I don't know where to get a list of them from. Andy Re: Processing after suspend or hibernate Andy Henderson3-Aug-04 8:20 Andy Henderson 3-Aug-04 8:20  After a lot of research I managed to answer my own question. During the log in process the OS displays a different desktop - and that can be detected in a VB.net program as follows... Declare Function GetThreadDesktop Lib "User32" (ByVal dwThread As Integer) As Integer Declare Function OpenInputDesktop Lib "User32" (ByVal dwFlags As Integer, ByVal fInherit As Boolean, ByVal dwDesiredAccess As Integer) As Integer Declare Function GetUserObjectInformation Lib "User32" Alias "GetUserObjectInformationA" (ByVal hObj As Integer, ByVal nIndex As Integer, ByRef pvInfo As Byte, ByVal nLength As Integer, ByRef lpnLengthNeeded As Integer) As Integer ... Dim MyDesktopName(254) As Byte Dim MyDesktopNameLength As Integer = 0 Dim InputDesktopName(254) As Byte Dim InputDesktopNameLength As Integer = 0 Dim StringLength As Integer = 255 Dim UOI_Name As Integer = 2 Dim x As Integer Dim z As Integer ... 'Get name of the program's desktop x = GetThreadDesktop(AppDomain.GetCurrentThreadId) z = GetUserObjectInformation(x, UOI_Name, MyDesktopName(0), StringLength, MyDesktopNameLength) 'Get name of the active desktop x = OpenInputDesktop(0, False, 0) z = GetUserObjectInformation(x, UOI_Name, InputDesktopName(0), StringLength, InputDesktopNameLength) For i = 0 To 254 If InputDesktopName(i) <> MyDesktopName(i) Then 'Here if the program is not running on the active desktop 'Eg. if login screen is showing after hibernate or suspend, 'or a password-protected screen saver.
