c# - How to take screen shot of MDI form while clicking on any Toolstrip menu item -

I tried the following C # code, but when taking a snapshot, also part of the opened part in the image Is the file menu I need some help to capture the screen after the click event and before clicking the save button, but should not be part of the opened file menu in it

  Private Zero viewviewsstrip menuItmclClique (Object sender, eventarges e) {string filename = ""; Bitmap screen = new bitmap (network_drawing_panel.Wide, Network_drawing_panel.html -50); Use (graphics g = graphics. Framesize (screen)) {g.CopyFromScreen (0, 80, 0, 0, screen size); } // SaveFileDialog SaveFileDialog dlg = new SaveFileDialog (); Dlg.InitialDirectory = @ "C: \\ Picture"; Dlg.DefaultExt = ".jpg"; Dlg.Filter = "JPEG Images (.jpg) | * .jpg | All Files (*. *) | *. *"; Dlg.Title = "Save an Image File"; If (dlg.ShowDialog () == DialogResult.OK) {filename = dlg.FileName; {Try the screen. Save (File Name, System. Drawing Imaging. Format .jpg); } Catch (Exception C) {Console.WriteLine (c.ToString ()); }}}    This is my snap shot.   
 
  The basic way to do this is to use postmessage, before the operation is complete, the current dispatch is completely Completion is allowed.  
 PostMessage is equivalent to WinForms (a form is a control).    WinForms uses PostMost to actually perform delegates from PostInfo.

visual studio 2010 - How to reinstall MVC 2 tools for VS2010? -



    I uninstalled ASP.Net MVC 2 device for Visual Studio 2010. How can I restore it? MVC2 downloads seem to include only the VS2008 device.   Whatever I said, says that MVC 2 has been included in VS2010, but the installation of an improvement did not fix it, and MVC 2 is not listed. Add VS2010 / Select a component in the Remove screen.      You will get your VS2010ToolsMVC2.msi VS2010 DVD under WCU \ ASPNETMVC - hopefully it will do!    






Git Bash script to check whether repo has any commits? -



    I have a script on which I need to work differently if there is one, which is one or more , Commits. What is the best way to do this?   Something like this will appear in the proxy code.    #! / Bin / bash if [[`git log_count`] ==" 0 "]]; Then there is no commodity for this repo. # What goods ... and echo are "one or more committed!" # What are the other things?    Any ideas?      you can    git rev-parse -verify HEAD    (after :)     This is a pipeline command, and its behavior vs. "  git diff " There is very little possibility to change   I find it more pronounced  rev-parse -verify  means "is this a valid object name?"    This is your  show-ref .  You ask "Is there anything in this safe / head in the safe?"  I ask, "what current  head  exists?"   In practice, both of these are fair tests, because once you have a branch, so to achieve the  HEAD , some mock values will indicate manually lack of editing It is very diffic...
