Invalidate刷新的问题

[shore1000]

/*双击选择框控件*/
void CSetPlateLine::OnSelectlineCombox()
{
m_bCheck = 1;
OnPaint();
}

/*刷新控件*/
void CSetPlateLine::OnPaint()
{
int iTempCurSel = m_comSelectLine.GetCurSel();
if(m_nIsChanged == 1)
{
m_nCurrent = iTempCurSel;
m_comSelectLine.GetLBText(m_nCurrent,m_strSelectLine);
if(m_strSelectLine == "单行")
{
DrawSignalLineImage();
}
else if(m_strSelectLine == "双行")
{
DrawDoubleLineImage();
}
m_nIsChanged = 0;
m_bCheck = 0;
}
else if(m_bCheck == 1)
{
Invalidate();
m_bCheck = 0;
m_nIsChanged = 1;
}
CDialog::OnPaint();
}
发现我点两次选择控件中的单行才有画图显示,第一次是空的,第二次才画出图像来.
我要的结果是点击一下选择对话框控件就直接覆盖掉上次画的图像,显示这次图像,请高手指定

问题已经解决,
void CSetPlateLine::OnSelectlineCombox()
{
int iTempCurSel = m_comSelectLine.GetCurSel();
if(iTempCurSel != m_nCurrent)
{
m_nCurrent = iTempCurSel;
m_comSelectLine.GetLBText(m_nCurrent,m_strSelectLine);

this->InvalidateRect(NULL,1);
this->UpdateWindow();

if(m_strSelectLine == "单行")
{
DrawSignalLineImage();
}
else if(m_strSelectLine == "双行")
{
DrawDoubleLineImage();
}
}
}

/*刷新控件*/
void CSetPlateLine::OnPaint()
{
CDialog::OnPaint();
}

要分的速度来,一会结贴了

RedrawWindow

改成这样试试：

/*双击选择框控件*/ 
void CSetPlateLine::OnSelectlineCombox() 
{ 
	m_bCheck = 1; 
	Invalidate(); 
	UpdateWindow();
} 

/*刷新控件*/ 
void CSetPlateLine::OnPaint() 
{ 
	int iTempCurSel =  m_comSelectLine.GetCurSel(); 
	if(m_nIsChanged == 1) 
	{ 
		m_nCurrent = iTempCurSel; 
		m_comSelectLine.GetLBText(m_nCurrent,m_strSelectLine); 
		if(m_strSelectLine == "单行") 
		{ 
			DrawSignalLineImage(); 
		} 
		else if(m_strSelectLine == "双行") 
		{  
			DrawDoubleLineImage(); 
		} 
		m_nIsChanged = 0; 
		m_bCheck = 0; 
	} 
	else if(m_bCheck == 1) 
	{ 
		m_bCheck = 0; 
		m_nIsChanged = 1; 
	} 
	CDialog::OnPaint(); 
}

楼上的兄弟,代码测试后,发现一副图像都没画出来
