问题 I am using the CL2Cap class in the Widcomm SDK on Win7. I am able to successfully establish the L2CAP connection and send the UNIT INFO command but the data returned is incorrect. I suspect that the stack has already established a connection and the AVRCP spec says: "Only one L2CAP connection shall be established between AVCTP entities. If the connection already exists, the CT/TG shall not initiate the connection request." Can anyone shed some light on what could be the problem? I have

问题 I inherited a web application that makes calls to a web service. It is being developed in VS2008 SP1 and deployed to IIS6 (2k3 Server R2). Since I upgraded to Windows 7 Enterprise RTM, the following line gets added to my Web.config: <extendedProtectionPolicy policyEnforcement="Never" /> The problem is that when I deploy this application to my web server I get the following error: The element 'transport' cannot contain child element 'extendedProtectionPolicy' because the parent element's

问题 I am trying to register a permanent WMI event on my machine, where if a file is created in the folder C:\test , a script should run. I have successfully managed to register similar events where the action is to log a line to a file, but for some reason when trying to execute a script I just get no response. Here is the query I am using: $query=@" Select * from __InstanceCreationEvent within 10 where targetInstance isa 'Cim_DirectoryContainsFile' and targetInstance.GroupComponent='Win32

问题 How do you call IFileOpenDialog and IFileSaveDialog from VBA? According to Microsoft, applications written for Windows 7 and later should use IFileOpenDialog/IFileSaveDialog API calls instead of GetOpenFileName/GetSaveFileName (see Using the Common File Dialog). This is especially important for full Library support. 回答1: Short answer: it's probably not worth the effort. Longer answer: the CFD interfaces don't extend IDispatch, which makes them impossible to call via late binding from VBA.

问题 I am working on Visual SourceSafe, for that I am trying to install the VSS update 2005. At the time of installing I am getting the following Error message: "The upgrade patch cannot be installed by the Windows Installer service because the program to be upgraded may be missing, or the upgrade patch may update a different version of the program.Verify that the program to be upgraded exists on your computer and that you have the correct upgrade patch." Can you give me the solution for the above

问题 I have a service running in Windows 7. In Windows 7 all services run in Session 0. From that service I want to create an interactive user session (in a session other than Session 0) and start an application in that session. My problem is that when I call LogonUser to start an interactive user session and then use CreateProcessAsUser to start the application the application ends up running in Session 0. All of my code is C#. Here is the relevant code: [DllImport("advapi32.dll", SetLastError

问题 I have the following segment of code where m_edit is a CEdit control: TCHAR lpsz[MAX_PATH+1]; // get the edit box text m_edit.GetLine(0,lpsz, MAX_PATH); This works perfectly on computers running Windows XP and earlier. I have not tested this in Vista, but on Windows 7, lpsz gets junk unicode characters inserted into it (as well as the actual text sometimes). Any idea as to what is going on here? 回答1: Since you're using MFC, why aren't you taking advantage of its CString class? That's one of

问题 Using a bat file, I want to change to a sub directory of folder which bat file is in, and run my_application.exe in that directory, I try: cd /d %cd%\my subdirectory START %~dp0my_application.exe But it doesn't work, it says it can't find my_application.exe 回答1: Just indicate to start command what program to start and what should be the starting folder for it. Without the cd command, it can be written as start "" /d "%~dp0my_subdirectory" "my_application.exe" if the my_application.exe is

问题 Is it possible to capture the 'live' thumbnails from the Win7 taskbar? I want to display this preview (of another window) in my application, but how to extract those previews using .NET? 回答1: Yes. MSDN Magazine explains how. You can also use the Windows API Code Pack, which handles the interop for you. 回答2: There's a System.Windows.Shell namespace in .NET 4 that enables you capture thumbnails, etc. See http://blogs.msdn.com/b/usisvde/archive/2010/03/18/windows-7-taskbar-features-in-net-4.aspx
