从dll创建CListCtrl [英] Create CListCtrl from dll

问题描述

---------------------------DLL A----------------------------------
#ifdef SELIBCTRL_IMP
#define SELIBCTRL_API           __declspec(dllexport)
#define SELIBCTRL_EXT_CLASS    AFX_CLASS_EXPORT
#else
#define SELIBCTRL_API           __declspec(dllimport)
#define SELIBCTRL_EXT_CLASS    AFX_CLASS_IMPORT
#endif

class IListCtrl
{
   ...
};

SELIBCTRL_API IListCtrl* CreateIListCtrl(HWND hParent);

class CMyListCtrl : public CListCtrl, public IListCtrl
{
     ...
};
----------------------------DLL B------------------------------
void Test::CreateList()
{
    IListCtrl* pList = CreateIListCtrl(this->GetSafeHwnd());
}
---------------------------------------------------------------

我使用dll介面建立CMyListCtrl，并覆写DrawItem()，
但它无法接收ownerdraw消息，因此DrawItem()始终不运行，只能接收move事件.

PS:我尝试使用AFX_MANAGE_STATE(AfxGetStaticModuleState())，但它没有用

如果不使用A dll，请将CMyListCtrl类移至B dll，就可以了，
为什么会出现这个问题?谁能给我一个建议?谢谢.

致:Richard MacCutchan
创建此CListCtrl时已经设置了样式.
但是，非常感谢您的回答^^

I use a dll interface to create a CMyListCtrl, and override DrawItem(),
but it cant receive ownerdraw message,so DrawItem() is always not running, only can receive move event.

PS:I try use AFX_MANAGE_STATE(AfxGetStaticModuleState()), but its no useful

If dont use A dll, move the CMyListCtrl class to the B dll, it will be OK,
Why is this problem? Can anyone give me a suggestion? Thanks.

TO: Richard MacCutchan
I have already set the style when i create this CListCtrl.
But, thanks a lot of you answer^^

推荐答案

您在调用LVS_OWNERDRAWFIXED样式.microsoft.com/en-us/library/hyyed8e0(VS.80).aspx> CListCtrl::CreateEx() [

You need to include the LVS_OWNERDRAWFIXED style in your call to CListCtrl::CreateEx()[^].
