Some preamble… A Runtime Callable Wrapper (RCW) only calls IUnknown.AddRef once on the unmanaged COM interface that it wraps. However, an RCW also maintains a separate count of the number of managed references there are to the RCW itself. It is this separate count of managed references that is decremented by a call to Marshal.ReleaseComObject. … Read more
You’ll need to add a reference to WindowsFormsIntegration. If you do a Add Reference in Visual Studio, it will be near the last DLL available in the .Net tab On my machine it’s located at %ProgramFiles%\Reference Assemblies\Microsoft\Framework\v3.0\WindowsFormsIntegration.dll
do I just import java.io.Serializable Yes. Just be aware that Kotlin uses @Transient annotation instead of a keyword. Of course, Java serialization does have its issues, but there’s no difference in that respect between Kotlin and Java, and if you are happy with your current code…
Depends on what type of DLL. Is this built in .NET ? if it is unmanaged code then here is an example otherwise the Answer from Rob will work. Unmanaged C++ dll example: using System; using System.Runtime.InteropServices; You may need to use DllImport [DllImport(@”C:\Cadence\SPB_16.5\tools\bin\mpsc.dll”)] static extern void mpscExit(); or [DllImport(“user32.dll”, CharSet = CharSet.Unicode)] public static … Read more
Looking at the documentation here http://msdn.microsoft.com/en-us/library/microsoft.office.tools.excel.worksheet.move(v=vs.80).aspx, it indicates that the ‘after’ object isn’t a numerical position; it’s the object representing the sheet you want to position your sheet after. The code should probably be something like (untested): workbook.Sheets.Add(After: workbook.Sheets[workbook.Sheets.Count]);
In .net 4 static Add() and Subtract() methods have been added. IntPtr ptr = IntPtr.Add(oldPtr, 2); http://msdn.microsoft.com/en-us/library/system.intptr.add.aspx
You can’t access a static member via COM interop. In fact your code doesn’t even compile, the method should be in a class. Here is how you can do it: [InterfaceType(ComInterfaceType.InterfaceIsDual)] [Guid(“01A31113-9353-44cc-A1F4-C6F1210E4B30”)] //Allocate your own GUID public interface _Test { string HelloWorld { get; } } [ClassInterface(ClassInterfaceType.None)] [Guid(“E2F07CD4-CE73-4102-B35D-119362624C47”)] //Allocate your own GUID [ProgId(“TestDll.Test”)] public class … Read more
For some reason (I haven’t yet investigated why) not (obj.ReferenceEquals(value, null)) performs much better than value <> null. I write a lot of F# code that is used from C#, so I keep an “interop” module around to ease dealing with null. Also, if you’d rather have your “normal” case first when pattern matching, you … Read more
Do you not need to call Quit? app.Quit();
You can use the module called win32clipboard, which is part of pywin32. Here is an example that first sets the clipboard data then gets it: import win32clipboard # set clipboard data win32clipboard.OpenClipboard() win32clipboard.EmptyClipboard() win32clipboard.SetClipboardText(‘testing 123’) win32clipboard.CloseClipboard() # get clipboard data win32clipboard.OpenClipboard() data = win32clipboard.GetClipboardData() win32clipboard.CloseClipboard() print data An important reminder from the documentation: When the … Read more
