问题 I want to forward the mouse scroll event from a control to its direct parent (which is also UserControl in my case). How is this possible? Edit The control is added to a control that is scrollable. Like a memo-edit for example. When the user scrolls in the memo-control, the memo-control is scrolled (!) But when the user scrolls on top of the custom control the event is not forwared to the parent control and the memo-control does not scroll. 来源： https://stackoverflow.com/questions/10041923

问题 I am passing the parameter to the function as a var type. It is not accepting, how do I pass to the function? Example var Input = ................ listview1.itemsource = getinput(Input); public List<answers>getinput(var inp) { ................ .................. } Here the function is not accepting the var . What can I do? 回答1: var can only be used when a local variable is declared and initialized in the same statement; the variable cannot be initialized to null, or to a method group or an

问题 I've seen older posts here on SO, about one year old which would mean that they do not really cover .NET 4 or maybe even 3.5 on this topic. So here goes. If you with reflection were to fetch parameters for the current method ParameterInfo[] methodParams = MethodInfo.GetCurrentMethod().GetParameters(); Looping through each parameter will let you fetch the parameter-name however, there is only a "DefaultValue" which I guess is there because of the new Dynamic Parameters in .NET 4. However, my

问题 I have a service(Language: VB.NET, Framework:.NET 3.5) that returns a dataset from which I read a date. The value of the column in the database is: "1980-03-30 00:00:00.000". In a client(Language: C#) that uses .NET 3.5, the value is coming thorough as : 3/30/1980 12:00:00 AM However, when I change the same client to use .NET 4 or .NET 4.5, the date which comes through the service is: 3/29/1980 11:00:00 PM 回答1: The difference in DateTime values is not because of .Net framework, its because of

问题 I would like to skin a wpf default checkbox to something custom. Since it does not really make sense to start off a entirely new control, i'd like to override the Windows Chrome template binding for the Bulletchrome sub component of the checkbox. However I cannot do this like I can with checkboxes for example. tried using something like this to override the default style, but it seems to not compile like this <Style x:Key="cb_BULLETSTYLE" TargetType="{x:Type BulletDecorator}"> <Setter

问题 I am working on an Filter Attribute for ASP.Net MVC that will return a 304 response when the content has not been modified. It would be handy to be able to read the Last-Modified header value set in the Controller in order to accomplish this... there just seems to be one problem. I can't seem to find a way to read the headers when executing code like the following on Cassini [Visual Studio 2008 Dev Web Server]... Response.AddHeader("Last-Modified", lastModified); string getLastModified =

问题 After reading Dynamically calling unmanaged dlls in .net I've been trying to modify the code to my liking. I made a class that implements idisposable to wrap load calls in and free them when needed. However I can't seem to figure out the syntax if it is possible to use anonymous delegates with it. var loaded=DynamicLibraryLoader.TryLoad("User32.dll"); var beeper=loaded.GetProcAddress("MessageBeep"); var type=typeof(Action<UInt32>); Action<UInt32> beepAction2=(Action<UInt32>) Marshal
