IContextMenuCallback.AddItem失败 [英] IContextMenuCallback.AddItem failure

问题描述

我一直在努力在.NET 4.0中实现IExtendContextMenu.我已经正确调用了接口，但是当我尝试添加菜单项时，我似乎无法通过System.Argument异常，并且该异常仅提供信息 CONTEXTMENUITEM值之一超出范围.在下面，我将显示我正在使用的导入信息.

I have been working on implementing IExtendContextMenu in .NET 4.0.  I have got the interfaces being called correctly, but when I try to add my menu item, I can't seem to get past the System.Argument exception and the exception only provides information that one of the CONTEXTMENUITEM values is out of range.  Below, I will show the import information that I am using.

首先，失败的函数调用:

First, the function call that is failing:

   CONTEXTMENUITEM l_item = new CONTEXTMENUITEM();
   l_item.fFlags = 0;
   l_item.fSpecialFlags = 0;
   l_item.lCommandID = MMC_VERB.PROPERTIES;
   l_item.lInsertionPointID = CCM.INSERTIONPOINTID_PRIMARY_TASK;
   l_item.strName = l_text;
   l_item.strStatusBarText = l_text;

   piCallback.AddItem(ref l_item);

其中piCallback是对传递到IExtendContextMenu.AddMenuItems中的IContextMenuCallback接口的引用.现在获取支持代码:

where piCallback is a reference to the IContextMenuCallback interface that is passed into IExtendContextMenu.AddMenuItems.  Now for the supporting code:

IContextMenuCallback:

IContextMenuCallback:

[ComImport(), InterfaceType(ComInterfaceType.InterfaceIsIUnknown), Guid("43136EB7-D36C-11CF-ADBC-00AA00A80033")]
 public interface IContextMenuCallback
 {
  void AddItem(ref CONTEXTMENUITEM pItem);
 }

上下文菜单项:

 [StructLayout(LayoutKind.Sequential)]
 public struct CONTEXTMENUITEM
 {
  [MarshalAs(UnmanagedType.LPWStr)]
  public String strName;
  [MarshalAs(UnmanagedType.LPWStr)]
  public String strStatusBarText;
  public long lCommandID;
  public long lInsertionPointID;
  public long fFlags;
  public long fSpecialFlags;
 }

MMC_Verb:

 public class MMC_VERB
 {
  public const uint NONE = 0x0000;
  public const uint OPEN = 0x8000;
  public const uint COPY = 0x8001;
  public const uint PASTE = 0x8002;
  public const uint DELETE = 0x8003;
  public const uint PROPERTIES = 0x8004;
  public const uint RENAME = 0x8005;
  public const uint REFRESH = 0x8006;
  public const uint PRINT = 0x8007;
  public const uint CUT = 0x8008;

  public const uint MAX = 0x8009;
  public const uint FIRST = OPEN;
  public const uint LAST = MAX - 1;
 }

有人对我可能会出错的地方有任何见解吗?

Anyone have any insights of where I may be going wrong?
