在Win32 ListView中，我有常规和状态图标。这适用于Win7，但不适用于XP

Question

我已经看过Microsoft文档，但它表示应该没有区别。

请注意，这是一个虚拟的ListView，因此如果在LV_ITEM :: mask中设置了LVIF_STATE标志，我将在实现LVN_GETDISPINFO消息的代码中提供状态图标索引。

有没有人知道任何可能导致这种行为差异的细微差异？

不张贴在你的问题并不完全帮助任何示例代码...

此代码的工作对我来说：

#include <Windows.h> 
#include <commctrl.h> 
#pragma comment(lib, "comctl32.lib") 

typedef struct { 
    LPTSTR text; 
    UINT icon; 
    UINT stateicon; 
} MYITEM; 
HWND g_hLV=NULL; 
MYITEM g_myitems[2]={{"item1",0,0},{"item2",2,2}}; 

LRESULT CALLBACK WndProc(HWND hwnd,UINT msg,WPARAM wp,LPARAM lp) 
{ 
    switch(msg) 
    { 
    case WM_NOTIFY: 
     if (lp) 
     { 
      NMLVDISPINFO*pLVDI=(NMLVDISPINFO*)lp; 
      NMLISTVIEW*&pLV=(NMLISTVIEW*&)pLVDI; 
      switch(pLVDI->hdr.code) 
      { 
      case LVN_GETDISPINFO: 
       if (LVIF_TEXT&pLVDI->item.mask) pLVDI->item.pszText=g_myitems[pLVDI->item.iItem].text; 
       if (LVIF_IMAGE&pLVDI->item.mask) pLVDI->item.iImage=g_myitems[pLVDI->item.iItem].icon; 
       if (LVIF_STATE&pLVDI->item.mask) 
       { 
        pLVDI->item.state=INDEXTOSTATEIMAGEMASK(1+g_myitems[pLVDI->item.iItem].stateicon); 
        pLVDI->item.stateMask=pLVDI->item.state; 
       } 
       return 0; 
      } 
     } 
     break; 
    case WM_CREATE: 
     { 
      g_hLV=CreateWindowEx(WS_EX_CLIENTEDGE,WC_LISTVIEW,0,WS_VISIBLE|WS_CHILD|LVS_OWNERDATA|LVS_REPORT|LVS_SHAREIMAGELISTS,0,0,0,0,hwnd,0,0,0); 
      LVCOLUMN lvc={LVCF_TEXT|LVCF_WIDTH}; 
      lvc.pszText="dummy"; 
      lvc.cx=99; 
      ListView_InsertColumn(g_hLV,0,&lvc); 
      SHFILEINFO sfi; 
      HIMAGELIST hil=(HIMAGELIST)SHGetFileInfo(".\\",FILE_ATTRIBUTE_DIRECTORY,&sfi,0,SHGFI_SMALLICON|SHGFI_SYSICONINDEX|SHGFI_USEFILEATTRIBUTES); 
      ListView_SetImageList(g_hLV,hil,LVSIL_SMALL); 
      ListView_SetImageList(g_hLV,hil,LVSIL_STATE); 
      g_myitems[1].stateicon=g_myitems[1].icon=sfi.iIcon;//assuming the imagelist has icons is wrong, so set at least one of them to a valid index 
      ListView_SetCallbackMask(g_hLV,LVIS_STATEIMAGEMASK); 
      ListView_SetItemCount(g_hLV,2); 
     } 
     return 0; 
    case WM_SIZE: 
     SetWindowPos(g_hLV,0,0,0,LOWORD(lp),HIWORD(lp),SWP_NOZORDER|SWP_NOACTIVATE); 
     break; 
    case WM_DESTROY: 
     PostQuitMessage(0); 
     break; 
    } 
    return DefWindowProc(hwnd,msg,wp,lp); 
} 

int WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPSTR lpCmdLine,int nShowCmd) 
{ 
    InitCommonControls(); 
    //This dialog subclassing is a ugly hack, but this is just sample code! 
    HWND hwnd=CreateWindowEx(0,WC_DIALOG,"LVTest",WS_OVERLAPPEDWINDOW,0,0,99,99,0,0,0,0); 
    SetWindowLongPtr(hwnd,GWLP_WNDPROC,(LONG_PTR)WndProc); 
    SendMessage(hwnd,WM_CREATE,0,0); 
    ShowWindow(hwnd,nShowCmd); 
    MSG msg; 
    while (GetMessage(&msg,0,0,0) > 0) 
    { 
     TranslateMessage(&msg); 
     DispatchMessage(&msg); 
    } 
    return msg.wParam; 
}
