c++ - 获取状态栏文本

Question

我正在尝试从我的程序状态栏中检索文本，以便我可以在 wm_drawitem 事件期间使用它。以下代码为 statustext 返回零值，而不是第一个窗格文本。

char statusText[1024];

int nLength = SendMessage(hStatus, SB_GETTEXTLENGTH, (WPARAM)0, 0);
int len = SendMessage (hStatus, SB_GETTEXT, (WPARAM)0, (LPARAM)statusText);

有什么我想念的想法吗？

状态栏设置如下：

int parts[3] = { 100, 408, 508};
SendMessage(hStatus, SB_SETPARTS, 3, (LPARAM)&parts);
SendMessage(hStatus, SB_SETTEXT, SBT_OWNERDRAW|SBT_NOBORDERS|0, (LPARAM)"Ready");
SendMessage(hStatus, SB_SETTEXT, SBT_OWNERDRAW|SBT_NOBORDERS|1, (LPARAM)NULL);
SendMessage(hStatus, SB_SETTEXT, SBT_OWNERDRAW|SBT_NOBORDERS|2, (LPARAM)timeStr); 
SendMessage(hStatus, SB_SETBKCOLOR , 0, (LPARAM)RGB(219,227,250));
