• 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. It seems that SendInput(1, &ipEvent, sizeof(INPUT)) was not introduced to vc6.0 when vc6 was released, so I can not use SendInput in vc6, please tell me wha ...Show All

• SQL Server Status of Replication Through Transact-SQL

  Hello, I currently have a transactional replication between SQL Server 2000 and an Oracle database. Once a week on Monday mornings we have a process that drops replication, uploads data to the SQL Server database from Oracle, does some manipulation of the data and then recreates replication. We came across the thought of what would happen if replication had erred out and there were still transactions within the distribution database to be replicated across. Then our job just came about and dropped the replication. We are looking for a way to tell what the status is of replication through Transact-SQL. This way we can check the status and if it contained an error that we could abort the job, so as to not lose any transactions. D ...Show All

• Visual Studio 2008 (Pre-release) Adding Web Reference in VS 2005 to WCF Service

  Hello, As I’ve found out yesterday, it’s important to create a proxy class for ‘WCF web service’ using svcutil.exe even though it uses 'basicHttpBinding'. If one does it through VS2005's 'add web service' routine, the created proxy allows passing string fields only. All value types doesn't go through. I mean the proxy class looks correct with all fields having correct types. But when I attach the debugger to the WS I see default values only for types like int, short, DateTime etc. Am I doing something wrong nefis Nefis, Do you have the Visual Studio Extensions for .Net 2.0 installed If so you can use "add service reference" instead of "add web reference."
