wpf controls - How to make Thumb non-draggable after certain Height and Width in WPF? -

I have a resizable button whose control template has thumbs up among other things:

  & Lt; ControlTemplate x: key = "ResizableButtonTemplate" TargetType = "{x: type button}" & gt; & Lt; Grid & gt; & Lt ;! - Other Stuff - & gt; & Lt; Thumb height = "3" cursor = "sizeN" margin = "0 -4 0" vertical alignment = "top" horizontal align = "statch" /> & Lt; Thumb width = "3" cursor = "size" "margin =" - 4 0 "workspaceElement =" statchch "horizontal alignment =" left "/> ...  gt; & lt; / ControlTemplate>    Now I would like that these thumbs are non-dragable after the user reaches some height and width. I tried to use MaxHeight and MaxWidth, But this did not help. Anyone from here can help me!   
 
  In the Drag Delta event handler of the Top, where you also change the size of the button (?), You can limit the maximum size when dragging goes to the acceptable size, you do not allow change.  
 Something like this:  
  DrugDelta at zero (object sender, drag deltaant ergues e) {// no real code if (actual sizeofbutton + new shape (E. Horizontal change, E. Vertical Change)) MaxSize {// button size adjustment Industry Ministers in}}

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...
