请大师ccrun和各位大侠指点关于读其他应用程序中ListView

[ywzywz]

我读5列数据不显示请指导

#include <vcl.h>
#pragma hdrstop

#include "Unit1.h"
//---------------------------------------------------------------------------
#pragma package(smart_init)
#pragma resource "*.dfm"
TForm1 *Form1;
//---------------------------------------------------------------------------
__fastcall TForm1::TForm1(TComponent* Owner)
: TForm(Owner)
{
ListView = new TListView(this);

ListView->Parent = this;
ListView->Align = alClient;
ListView->ViewStyle = vsReport;

NewColumn = ListView->Columns->Add();
NewColumn->Caption = "股票代码 ";

NewColumn = ListView->Columns->Add();
NewColumn->Caption = "预警条件 ";
NewColumn = ListView->Columns->Add();
NewColumn->Caption = "预警时间 ";
NewColumn = ListView->Columns->Add();
NewColumn->Caption = "预警价格 ";
NewColumn = ListView->Columns->Add();
NewColumn->Caption = "现价/盈亏 ";

// 上面的((void *)0x000100DC是我用MiniSpy取得的桌面的名柄(win2000下的桌面是个ListView)，在实际调用时换成你取得的ListView的句柄即可。并且在上面的这段代码只是获取ListView的Item的Caption的。
// 如
// HWND hListView;
//....获取ListView的句柄
// MyGetListViewItem(hListView,Memo1->Lines);
//如果其ViewStyle为vsReport，就要考虑读取ListView的HeadItem了。呵呵。GoodLuck.
