我如何使TreeControl的加载更快！

问题描述

你好，

我是VC ++编程的新手，有人可以通过TreeControl来帮助我.


大约有40000个元素(存储在一个数组中)要加载到Treecontrol中，大约需要2分钟，有人建议我一种更好，更快的方法吗?

代码片段是这样的:

Hello,

I am new to VC++ programming, could anyone help me with TreeControl.

There are around 40000 elements(stored in an array) to be loaded to a Treecontrol and it takes around 2 minutes, does anyone suggest me a better and faster way?

The snippet of code is something like this:

int CDerivedfromTreeView::OnCreate(LPCREATESTRUCT lpCreateStruct) 
{
    unsigned int    i,k;
    CTreeCtrl &controlList = (CTreeCtrl &) GetTreeCtrl(); 
    if (CTreeView::OnCreate(lpCreateStruct) == -1)
        return -1;
    controlList.ModifyStyle(0L, TVS_HASLINES | TVS_LINESATROOT | TVS_HASBUTTONS | TVS_NOTOOLTIPS | TVS_SHOWSELALWAYS ); 
    controlList.SetRedraw(TRUE);
    if(controlList.GetCount() )
    controlList.DeleteAllItems();
    controlList.SetRedraw(FALSE);

    for(i=0;i<global_Total_No_Of_Items;i++)
    {
        controlList.InsertItem( (LPCTSTR)items[i].name ,TVI_ROOT,TVI_LAST);
        
    }
        controlList.SetRedraw(TRUE);
    SplitterWindow = CView::GetParentSplitter(this, TRUE);
    return 0;
}
