• Visual C++ simulate keyboard operation, but while compiling the program, it said: KEYBDINPUT and SendInput have not been defined.

  I want to use the following codes to simulate keyboard operation, but while compiling the program, it said: KEYBDINPUT and SendInput have not been defined. Please tell me why and the head file needed to be added. KEYBDINPUT ki; ki.wVk = VK_RETURN; ki.wScan = MapVirtualKeyEx(VK_RETURN, 0, GetKeyboardLayout(0)); ki.dwFlags = KEYEVENTF_EXTENDEDKEY; // or KEYEVENTF_KEYUP, one of those must work ki.time = 10000; ki.dwExtraInfo = 0; INPUT ipEvent; ipEvent.type = INPUT_KEYBOARD; ipEvent.ki = ki; UINT nNumEvents = SendInput(1, &ipEvent, sizeof(INPUT)); I appreciate your help. If you have a desktop machine with a PS/2 connector, the easiest way IMHO to simulate keyboard input is to just build a simple microcontroller circuit to interfa ...Show All

• Visual Studio MSCCI Get on multiple files isnt working for me...

  I am creating my own editor app that integrates with sourcesafe and have had various issues. I am using VS6 and the app is an MFC MDI app. The various issues I had were that the HWND passed has to be valid otherwise it says it succeeds and returns SCC_OK but actually it didnt. Other things like local project paths MUST not have a trailing slash (all horrible stuff, shame it doesnt error for me). Those being all solved, I am now trying to do a multiple file get again it comes back SCC_OK but nothing has been got. If I use my code to get the files one at a time, it works fine. The same code also works in a console app so I was wondering if its the HWND problem rearing its ugly head or if its something else ...Show All

• SQL Server How to specify a row filter on joined tables

  I am using SQL Server 2005 to publish joined tables for SQL Mobile subscribers for merge replication and column level tracking. Using Management Studio I am trying to join tables and specify row filters on the joined tables. I.E. table 1 is joined with table 2. I need to define row filters for table 1 and row filters specific to table 2. An example would be: Table 1 is a customer table that I filter on a specific customer. Table 2 might be an orders table that I need to join to get the customers orders but I also want to filter for open orders only. When I specify the row filter for table 2 the join appears to be ignored and I receive the complete table 2 with the row filter applied. I have searched the online books and the we ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Deployment / strange Network Problem

  Hello I have a problem with deployment of a xbox 360 game. Okay the problem seems to be the network connection, i get the message that the host (my xbox 360) cannot be reached. I tried a PING to the IP Address of my XBox 360 and it fails. So i checked the Subnet, the IP Address, everything looks fine. And than i figured out something really strange: I started "PING -t 192.168.0.2" (the IP of my XBox) and i got timeouts as before. Than i started the network diagnostic tool on the XBox - still PING timouts. From the moment on where the network diagnostics reached the ICMP test, the PING succeeded and i receive an answer. Unfortunatly when the network test is over, the PING fails again. Can someone help me Greetings, Ber ...Show All

• Visual C# How to load images effectively ?

  Hi guys, In my program I want to view thumbnails.. But when the original image size goes up the program starts to freeze.. In my method I directly load the original image to an Image object and then using the GetThumbnail(....) method resize it and pass to another Image object. But it seems this is not an effective way !! Is there any idea, or trick or something else to increase this performance I am open to any advice.. Best regards The documentation for GetThumbnailImage doesn't say how hard the method works on getting a good quality image. Probably as hard as possible. As an alternative, considering using Graphics.DrawImage to create your thumbnail with the Graphics.InterpolationMode set to Low. ...Show All

• Visual Studio 2008 (Pre-release) Lots of ListView Items in my ListView = LAAAAGG....

  My program is quite simple really, but for some reason, when I have a lot of items in my ListView, the program hates my computer, and slows the whole thing down kinda. When I have just a few items in there, it works just fine. But, when I'm getting an array of files from GetFiles(path, searchpattern, alldirectories) or whatever, and am putting it in the ListView, where there's ALOT of files listed in there, which I might need in my program, it slows it down. There could be over a thousand files in that ListView. I really don't know how many songs I have. But, what could be the issue here I am using the latest .NET Framework 3 (downloaded like 2 days ago), Visual C# 2005 Express Edition, and I'm running on Windows XP SP2 (latest updates, e ...Show All

• SQL Server Changing connection string dynamically and Reports calling performance
