如何从vc ++ 2008对话框中隐藏图像. [英] how to hide the image from the dialog vc++ 2008.

问题描述

你好..
MFC 2008中如何在if-else条件下隐藏和显示图像

解决方案

嘿，根据我的理解，您想在单击按钮时隐藏和显示图像.
所以下面的代码只是建议
在对话框.h文件中定义CPitureEx的对象.
像下面一样，

CPictureEx m_piture;

在对话框的OnInitDialog()中，只需提供以下代码行

if (m_Picture.Load(MAKEINTRESOURCE(IDR_FELIX),_T("GIF")))
m_Picture.Draw();   ///you can provide bitmap ID If you want draw bitmap

单击"HideShow()"按钮时不可以

HideShow()
{
  if(m_Picture.IsWindowVisible())
  {
      m_Picture.ShowWindow(0);
   }
   else
   {
    m_Picture.ShowWindow(1);
   } 
}

如果您谈论的是标题栏中的图标，则可以执行以下操作:

显示图标:

//get the main application icon for example
HICON m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);
//set big icon
SetIcon(m_hIcon, TRUE);
//set small icon
SetIcon(m_hIcon, FALSE);

隐藏图标:

//set big icon
SetIcon(NULL, TRUE);
//set small icon
SetIcon(NULL, FALSE);

不，我只在对话框中显示图像.此后，我想在单击按钮时隐藏. blockquote>

hello..
how to hide and show the image with in if-else condition im MFC 2008

解决方案

Hey What i understand according to this you want hide and show image on button click.
so following code is just suggestion
define object of CPitureEx in your dialog .h file.
like following,

CPictureEx m_piture;

in OnInitDialog() of you dialog just provide this lines of codes

if (m_Picture.Load(MAKEINTRESOURCE(IDR_FELIX),_T("GIF")))
m_Picture.Draw();   ///you can provide bitmap ID If you want draw bitmap

No on click of your HideShow() button

HideShow()
{
  if(m_Picture.IsWindowVisible())
  {
      m_Picture.ShowWindow(0);
   }
   else
   {
    m_Picture.ShowWindow(1);
   } 
}

For more information you may see this example

If you are talking about the icon in the title bar, then you can do something like that:

To show the icon:

//get the main application icon for example
HICON m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);
//set big icon
SetIcon(m_hIcon, TRUE);
//set small icon
SetIcon(m_hIcon, FALSE);

To hide the icon:

//set big icon
SetIcon(NULL, TRUE);
//set small icon
SetIcon(NULL, FALSE);

No,i just show the image in dialog box..after that i want to hide when we click on the button..vis versa i want to show..
