如何在MFC CSplitterWnd中显示两个OLEControl [英] How do I display two OLEControls in a MFC CSplitterWnd

问题描述

每个人早上好，



rigth现在我正在开展一个项目，我必须使用GDPicture来显示图像。

这个GDP图片库包括一些olecontrols为我做这件事，现在它很简单，但我必须扩展我们的程序，添加一个thumbnailviewer到我们构建的这个视图。



为了做到这一点，我认为使用CSplitterWnd并不是那么难，只需在左侧放置缩略图查看器的olecontrol和观察者身边。



我尝试了一些对话框和CFrameView类，但是当我覆盖create方法并在这个CFrameView中放置带有CreateControl的控件时，我总是会显示一条断言消息此时：



（winsplit.cpp第318行，CreateView）

 ASSERT（（ int ）_ AfxGetDlgCtrlID（pWnd-> m_hWnd）== IdFromRowCol（row，col））; 

基本上我只是这样做



（CThumbnailChild是CFormView的孩子）

 BOOL CThumbnailChild :: Create（LPCTSTR lpszClassName，LPCTSTR lpszWindowName，DWORD dwStyle， const  RECT& rect，CWnd * pParentWnd，UINT nID，CCreateContext * pContext）
 { 
  return  CreateControl（GdPicture_NET_9 :: CLSID_GdViewer，lpszWindowName，dwStyle，rect，pParentWnd，nID）; 
} 

对话框设置为：

边框：无

风格：儿童

控制：true





休息时默认设置适用





长话短说我只需要在CSplitterWnd中放置两个olecontrols，thumbnailviewer和图片查看器。




greetings

解决方案

< blockquote>一种可能的解决方案是将函数的MFC代码复制到项目中并修改它运行。

Good Morning every one,

rigth now I'm working on a project where I have to use GDPicture to display images.
This GDPicture lib includes some olecontrols to do this stuff for me and rigth now it is very simple but I have to extend our program an add a thumbnailviewer to this view we build.

In order to do that I thougth it couldn't be so hard to use a CSplitterWnd and just place on the left side the olecontrol for the thumbnail viewer and on the rigth side the viewer.

I tried a bit with dialogs and CFrameView classes but when I override the create method and place the controle with "CreateControl" in this CFrameView I always get an assert message displayed at this point:

(winsplit.cpp line 318,CreateView)

ASSERT((int)_AfxGetDlgCtrlID(pWnd->m_hWnd) == IdFromRowCol(row, col));

Basically I just do this

(CThumbnailChild is a child of CFormView)

BOOL CThumbnailChild::Create(LPCTSTR lpszClassName, LPCTSTR lpszWindowName, DWORD dwStyle, const RECT& rect, CWnd* pParentWnd, UINT nID, CCreateContext* pContext)
{
 return CreateControl(GdPicture_NET_9::CLSID_GdViewer, lpszWindowName, dwStyle, rect, pParentWnd, nID);
}

The Dialog Settings are:
Border: NONE
Style: Child
Control: true


At rest the default settings apply


Long story short I just need to place two olecontrols , thumbnailviewer and the picture viewer in a CSplitterWnd.

Many thanks for your help, I hope you understand my problem

greetings

解决方案

A possible solution is to copy the MFC code of the function into your project and modify that it runs.
