无法创建组件“AxHost" System.Runtime.InteropServices.COMException (0x80029C4A) [英] Failed to create component 'AxHost' System.Runtime.InteropServices.COMException (0x80029C4A)
问题描述
我在 C# 中创建了 .Net 用户控件.它是带有文本框和列表框的图形控件.现在我想在旧版 VC++ 应用程序中使用这个控件.(本机二进制).意味着我想从非管理代码调用管理代码.
I have created .Net usercontrol in C#. it is graphical control with a text box and listbox. Now I want to use this control in legacy VC++ application.(native binary). means I want to call manage code from unmanage code.
假设我的用户控件名称是 xyz.dll.我使用 tlbexp.exe 生成了 tlb 文件，然后我使用下面的命令行注册了这个控件.regasm xyz.dll/tlb:"C:\xyz.tlb"/codebase
suppose my usercontrol name is xyz.dll. I generated tlb file using tlbexp.exe and then i registered this control using below command line. regasm xyz.dll /tlb:"C:\xyz.tlb" /codebase
我已经使用Activex 控件测试容器"检查了我的控件(打开 studio 2005 并转到工具"菜单)我在这个工具上测试了我的 .Net 用户控件，它运行良好.
I have checked my control using 'Activex control test container' (open studio 2005 and go to 'tools' menu) I tested my .Net usercontrol on this tool and it worked fine.
然后我创建了一个示例 C# 窗口应用程序.在工具箱下，我右键单击并选择选择项目"并选择COM 组件"选项卡.并选择我的 xyz.dll 控件.现在此控件已添加到工具箱中.
then I created a sample C# window application. Under Toolbox, I right click and selected 'Choose Items' and selected "COM component" tab. and choose my xyz.dll control. now this contol is added into toolbox.
但是当我将此控件拖到窗口上时，出现以下错误.未能创建组件AxHost".错误信息如下:
But when I drag this control onto window then i got below error. Failed to create component 'AxHost'. The error message follows:
'System.Runtime.InteropServices.COMException (0x80029C4A):加载类型库/DLL 时出错.(来自 HRESULT 的异常:0x80029C4A (TYPE_E_CANTLOADLIBRARY))在 System.Windows.Forms.Design.DocumentDesigner.AxToolboxItem.CreateComponentsCore(IDesignerHost 主机)在 System.Drawing.Design.ToolboxItem.CreateComponentsCore(IDesignerHost 主机，IDictionary defaultValues)在 System.Drawing.Design.ToolboxItem.CreateComponents(IDesignerHost 主机，IDictionary defaultValues)在 System.Windows.Forms.Design.OleDragDropHandler.CreateTool(ToolboxItem tool, Control parent, Int32 x, Int32 y, Int32 width, Int32 height, Boolean hasLocation, Boolean hasSize, ToolboxSnapDragDropEventArgs e)'.

还给我一些指示如何将 .net usercontrol 用于遗留 C# 应用程序"
also give me some pointer "how to use .net usercontrol into legacy C# application"
推荐答案
目前没有足够的信息，但我的猜测是:
There is not enough information but my guess so far:
控件是在 .NET 4 中开发的，而传统的 C# 应用程序是在 .NET 2 中..NET 4 可以在同一进程中混合 .NET 版本，但 .NET 2 不能，所以我怀疑要解决这个问题，您需要在 .NET 2 中开发/构建控件，以便它可以在 .NET 2 & 中使用.4.
The Control is developed in .NET 4 and the legacy C# application is in .NET 2. .NET 4 can mix .NET-version in the same process, but .NET 2 can't so I suspect to solve this you need to develop/build the control in .NET 2 so that it is usable in .NET 2 & 4.
编辑(在关于 .NET 3.5 的评论之后):
EDIT (after the comment about .NET 3.5):
您需要通过运行 regsvr32 来注册控件.
You need to register the control by running regsvr32.
编辑 2:regsvr32 xyz.dll 或 regsvr32/i xyz.dll
