• Visual C# Application.Exit(); not working in the form constructor, why?

  Hello, I'm using Application.Exit(); in the form contructor to terminate the application if certain condition is met... but it's not working! Why and what can I do Thanks... I don't know, I find that wierd. difference between the 2: Application.Exit() -> informs all message pumps that they must terminate then closing all application Windows after the messages have been processed. It doesn't force the application to exit Environment.Exit() -> terminates the process giving the underlying OS the error code its terminated with. You need to have the SecurityPermissionFlag.UnmanagedCode permission otherwise you will be thrown a SecurityException ...Show All

• Visual Studio Express Editions precomiled header directives

  I am using some user defined header files and i have included the header files in the program but when i try to compile it, i get the following error: fatal error C1010: unexpected end of file while looking for precompiled header directive Error executing cl.exe. I went onto project->settings->c++ and changed the option to not use precompiled headers but it did not solve teh problem. I had a similar problem before but changing the project settings solved my problem but thats not the case anymore. Could someone shed some light on this please!! Thanks very much All i can suggest is that you create a new "empty project" and manually add in the files you need, that way you can be certain that ...Show All

• 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.

• Visual Studio Team System Data Compare - Next button grayed out

  Trying to a Data Compare. After I select my 2 data sources, I go to the next screen where I select the tables/views. I can select all tables or select individual tables, but no matter what I do the Next button is grayed out. Clicking the Finish button just closes the wizard without doing anything. What am I doing wrong I am running the initial CTP that was distributed at Tech Ed. Gert, I just want to add one thing to this. Your reply says "One obvious reason".

• SQL Server How to update a dimension column with the pipeline tasks

  I have been working with DTS and ETL in data warehousing projects for several years and my question is this. You can only update a dimension column with SSIS by using TSQL-update statements. There is no way to do this except issuing TSQL from the control flow or the data flow This subject is not mentioned in Wrox SSIS book nore in Kirk Haseldens book. When you run the SCD task in the data flow you will get an OLEDB command that actually do this, issue a TSQL-statement. Is this correct Regards Thomas Ivarsson Thomas Ivarsson wrote: I would prefer a graphical TSQL-task in the dataflow that will do this set based, not row by row.

• Visual Studio Team System VSS Migration hanging TF60047 - how to move forward?

  I am in the middle of running VSSConverter to migrate our source (~2GB) from VSS to TFS. It has been hanging for an hour or so with error # TF60047. The error message says there could be a problem with the network connection or TFS connection. I am running in a single server setup so TFS and SQL Server are all on the same machine, and all are running, incl. all SQL Server service - I checked in Configuration Mgr. One problem earlier was that there was huge (~800K) memory usage by w3wp.exe which was being run by the TFSService account. So I shut down IIS. Now, even though memory usage is down to acceptable levels, the migration is still not moving forward. Any ideas on how I can proceed here Or if I were to start afresh, how do I do that ...Show All
