VS错误：没有找到符号 为什么？


我建立一个窗体，在上面加了静态文本框，把它的ID 改成了IDC_STATIC1，然后再程序里面用到，为什么监视的时候总是说找不到符号？ 而且的确程序也不满足if条件，进不去。这是为什么？

IDC_STATIC1CXX0017: 错误: 没有找到符号“IDC_STATIC1”

C/C++ code

HBRUSH CCTDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor){    HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);    // TODO:  在此更改 DC 的任何属性     if (nCtlColor==IDC_STATIC1)      {             //将文本框IDC_STATIC1设置为透明              pDC->SetBkMode(TRANSPARENT);                   //返回一个空画刷              return (HBRUSH)GetStockObject(NULL_BRUSH);     }          return hbr;        //return m_brush;  返回另一个画笔    }

[解决办法]
你写错了吧，if判断错了吧
if(IDC_STATIC1 == pWnd->GetDlgCtrlID())
{
...
}

#include "resource.h"
[解决办法]
int nID = pWnd->GetDlgCtrlID();
if(nID == "控件ID")
{
............
}
