I have a form. All I want to do is display a section of that form on another form. I don't want it to be functional or anything. I basically just want it to be a picture. Is that possible, and if so, how? Like display = new display(form, new rectangle(X1, X2, Y1, Y2)); Is that a possibility? Yes you can do: Bitmap bmp = new Bitmap(myWidth, myHeight); myForm.DrawToBitmap(bmp, new Rectangle(x, y, bmp.Width, bmp.Height)); And then pass this bitmap to the other form. 来源： https://stackoverflow.com/questions/14612589/is-there-a-way-to-show-part-of-one-form-on-another-form

I need to use MemoryMappedFile class in .net 3.5... is there any way to find the code of the classes used in .net 4.0 and create to use in .net 3.5? thanks in advance If you need memory mapped files in .NET 3.5, you could also write your own wrapper around the respective Win32 methods from scratch. This might take a bit more effort, but it avoids any licensing issues. .NET 4 uses a whole new CLR, and I wouldn't be at all surprised to find that enough had changed under the hood to make this basically infeasible. Basically, you should be working to use a version of .NET that supports the

I'm using Visual Studio 2010 with .NET 4.0. I have a windows service that is installed from a Visual Studio Setup Project. In the setup project I have the RemovePreviousVersion property set to True. In the project that contains the service I have an installer class that will be used to stop the service when upgrading from a previous version. So when upgrading the software the service will already exist and could be running. If it is running then during the installation the installer prompts that the file is already in use and gives the option to Try Again, Continue or Exit Installation. At

Is this possible? I know it is for MS since they have WF activity packs but I'm not sure how it's done. It would be nice to be able to have Activities with Body blocks to insert other activities, buttons, etc. If not too much trouble and/or time consuming that is. Its easy enough if you follow a few rules. Here's an example of a NativeActivity that has a child: [Designer(typeof(MyActivityDesigner)), ContentProperty("Child")] public sealed class MyActivity : NativeActivity, IActivityTemplateFactory { // this "activity delegate" holds our child activity public ActivityAction Child { get; set; }

I'm using Unity IoC (Microsoft.Practices.Unity) and I can compile fine, but I'm getting the following error at run time: Could not load type 'System.Reflection.IntrospectionExtensions' from assembly 'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. The Unity version is: 3.0.1026.0 Is there a compatibility problem between .Net 4 and this version of Unity. Also, I get the same error when using Unity v2. If so, how might I go about resolving this issue? EDIT: Also, I've verified that mscorlib is referenced in my project. RESOLVED. Indeed I was using the .NET 4.5
