• Visual C++ noob programmer questions:)

  Hey guys Im new to programming and am teaching myself c++ with the visual c++.net express edition. I finally figured out how to build(compile) and run a simple program but now I have a new question. I click on start new project. then make my source file and name it. then i input a simple program, build and run it. now i click on add new source file and change the program around a little and when i try to build and run it, it wants to link with the other source file. How can I stop this linking together of source files in the same project so i can easily switch back and forth between the two Do I have to start a whole new project everytime I ...Show All

• Visual C++ Problem in setting PATH,LIB and INCLUDE environment variables through script for 32 and 64 bit plateforms.

  Hi, I'm using Visual Studio 2005 Professional Edition. I have a script file (batch file) to launch the devenv by using /useenv.

• Windows Forms DataGridView events master detail

  I have 3 nested DataGridViews (Parent, child, grandchild). Which event in the grandchild(most detailed) DataGridView should be used to capture when it's data has changed    Since it's bound to the child, which is bound to the Parent, it's data changes when either of these other two grid's change. I've tried the grandchild's DataBindingComplete and SelectionChanged events but these sometimes fire more than once when clicking (making selections) in the other two grids.  I can't seem to find any event in the grandchild grid that fires just once. VS 2005 Thank you. The DataBinding ...Show All

• Windows Forms Position of context menu

  Hi, How can I get the position of context menu Thank's Alexei Normally, the context menu will be shown at the center of the control when the keyboard is used to invoke the context menu of a control (Shift+F10, for example). You can customize the location as follows. Override WndProc in the grid and check if the Message.Msg is WM_CONTEXTMENU (0x007b) If so, check if the Message.LParam is -1, which means this was due to a keyboard message as opposed to the user right-clicking the mouse. Now, call the associated ContextMenu's Show method explicity at the selected row position. Make sure NOT to call the base class after show ...Show All

• Visual Studio Express Editions Updating the database

  I am asking a pretty common question it seems. Yes, I did look and do see the existing posts/responses. My problem is that I am not seeing the database actually get updated with new data. It seems fine at runtime, but if I shutdown the app and check the Db it is not getting back to the table. I also added some code from one of those VB for dummies books to help check that the update worked and it claims it is. I must be a different kind of dummy, lol. As I mentioned, I have seen the numerous responses regarding this issue, so I am quite puzzled as to why this isn't fising my problem. I checked the "copy to output di ...Show All
