如何以编程方式设置一个Outlook搜索文件夹中的自定义图标？ （即Outlook文件夹SetCustomIcon） [英] How to programmatically set a custom icon on an Outlook search folder? (i.e. Outlook Folder SetCustomIcon)

问题描述

我试图使用 Folder.SetCustomIcon（）方法来放在我编程方式创建一个保存搜索文件夹的自定义图标。在 SetCustomIcon（）文档是很稀疏，但可以的这里找到适合的参考。

另外，对象，预计是这里又一次的例子非常稀少。

请问有人知道如何设置自定义图标文件夹？下面的代码是我迄今：

  searchFolders = inboxFolder.Store.GetSearchFolders（）; 
的foreach（在searchFolders Outlook.Folder文件夹）
 {
如果（folder.Name ==即将到期保留策略邮件）
 {
 folder.ShowItemCount =微软.Office.Interop.Outlook.OlShowItemCount.olShowTotalItemCount; 
 folder.SetCustomIcon（新位图（32，32））; //< =  - 这是行不通的，因为它预期stdPicture这对如何转换这种类型很稀疏的信息。 
 Globals.ThisAddIn.Application.ActiveExplorer（）CurrentFolder =文件夹。 
} 
} 
  

解决方案

您只需要使用一个 PictureDispConverter 从图像/图标 IPictureDisp 去。下面是从MSDN 的例子。在展望2010 +这只能。要查看自定义的文件夹图标中的 Outlook 2013中，您需要的查看文件夹列表 - 不是邮件视图

从MAPIFolder SetCustomIcon

<预类=郎-CS prettyprint-覆盖> 私有静态无效SetCustomIcon（Outlook.MAPIFolder文件夹）
{
图标图标= NULL;
试
{
图标= Properties.Resources.myCustomIcon_16x16;
stdole.StdPicture iconPictureDisp = PictureDispConverter.ToIPictureDisp（图标）作为stdole.StdPicture;
folder.SetCustomIcon（iconPictureDisp）;
}
终于
{
icon.Dispose（）;
}
}


PictureDispConverter（ Icon-> IPictureDisp，图像 - > IPictureDisp 的）

返回PictureDispConverter.OleCreatePictureIndirect（pictIcon，楼盘iPictureDispGuid，真正的）;
}

//将图像转换成IPictureDisp。

I am attempting to use the Folder.SetCustomIcon() method to place a custom icon on a saved search folder I programmatically created. The SetCustomIcon() documentation is very sparse but can be found here for reference.

Also, the object it expects is here and again the examples are very sparse.

Would anybody know how to set the custom icon for a folder? The following is the code I have thus far:

searchFolders = inboxFolder.Store.GetSearchFolders();
foreach (Outlook.Folder folder in searchFolders)
{
    if (folder.Name == "Expiring Retention Policy Mail")
    {
        folder.ShowItemCount = Microsoft.Office.Interop.Outlook.OlShowItemCount.olShowTotalItemCount;
        folder.SetCustomIcon(new Bitmap(32, 32));   // <=-- this isn't working because it's expecting stdPicture which has very sparse information on how to convert to this type.
        Globals.ThisAddIn.Application.ActiveExplorer().CurrentFolder = folder;  
    }
}

解决方案

You just need to use a PictureDispConverter to go from an image/icon to IPictureDisp. Below is an example from MSDN. This only works in Outlook 2010+. To view custom Folder Icons in Outlook 2013, you need to view the Folder List - not the Mail view.

SetCustomIcon from MAPIFolder

private static void SetCustomIcon(Outlook.MAPIFolder folder)
{
    Icon icon = null;
    try
    {
        icon = Properties.Resources.myCustomIcon_16x16;
        stdole.StdPicture iconPictureDisp = PictureDispConverter.ToIPictureDisp(icon) as stdole.StdPicture;
        folder.SetCustomIcon(iconPictureDisp);
    }
    finally
    {
        icon.Dispose();
    }
}

PictureDispConverter (Icon->IPictureDisp, Image->IPictureDisp)

public static class PictureDispConverter
{
    //IPictureDisp GUID. 
    public static Guid iPictureDispGuid = typeof(stdole.IPictureDisp).GUID;

    // Converts an Icon into an IPictureDisp. 
    public static stdole.IPictureDisp ToIPictureDisp(Icon icon)
    {
        PICTDESC.Icon pictIcon = new PICTDESC.Icon(icon);
        return PictureDispConverter.OleCreatePictureIndirect(pictIcon, ref iPictureDispGuid, true);
    }

    // Converts an image into an IPictureDisp. 
    public static stdole.IPictureDisp ToIPictureDisp(Image image)
    {
        Bitmap bitmap = (image is Bitmap) ? (Bitmap)image : new Bitmap(image);
        PICTDESC.Bitmap pictBit = new PICTDESC.Bitmap(bitmap);
        return PictureDispConverter.OleCreatePictureIndirect(pictBit, ref iPictureDispGuid, true);
    }


    [DllImport("OleAut32.dll", EntryPoint = "OleCreatePictureIndirect", ExactSpelling = true,
    PreserveSig = false)]
    private static extern stdole.IPictureDisp OleCreatePictureIndirect(
    [MarshalAs(UnmanagedType.AsAny)] object picdesc, ref Guid iid, bool fOwn);

    private readonly static HandleCollector handleCollector =
    new HandleCollector("Icon handles", 1000);

    // WINFORMS COMMENT: 
    // PICTDESC is a union in native, so we'll just 
    // define different ones for the different types 
    // the "unused" fields are there to make it the right 
    // size, since the struct in native is as big as the biggest 
    // union. 
    private static class PICTDESC
    {
        //Picture Types 
        public const short PICTYPE_UNINITIALIZED = -1;
        public const short PICTYPE_NONE = 0;
        public const short PICTYPE_BITMAP = 1;
        public const short PICTYPE_METAFILE = 2;
        public const short PICTYPE_ICON = 3;
        public const short PICTYPE_ENHMETAFILE = 4;

        [StructLayout(LayoutKind.Sequential)]
        public class Icon
        {
            internal int cbSizeOfStruct = Marshal.SizeOf(typeof(PICTDESC.Icon));
            internal int picType = PICTDESC.PICTYPE_ICON;
            internal IntPtr hicon = IntPtr.Zero;
            internal int unused1 = 0;
            internal int unused2 = 0;

            internal Icon(System.Drawing.Icon icon)
            {
                this.hicon = icon.ToBitmap().GetHicon();
            }
        }

        [StructLayout(LayoutKind.Sequential)]
        public class Bitmap
        {
            internal int cbSizeOfStruct = Marshal.SizeOf(typeof(PICTDESC.Bitmap));
            internal int picType = PICTDESC.PICTYPE_BITMAP;
            internal IntPtr hbitmap = IntPtr.Zero;
            internal IntPtr hpal = IntPtr.Zero;
            internal int unused = 0;
            internal Bitmap(System.Drawing.Bitmap bitmap)
            {
                this.hbitmap = bitmap.GetHbitmap();
            }
        }
    }
}
