In the program, when you need to get an icon of other programs, we can first call the SDK function SHGETFILEINFO to get information about the application, and use the obtained HICON handle to display the icon display.
For example, if you need to display a write panel icon in the upper left corner of the program window (see Figure 1), you can add the following code in the corresponding view class onDRAW:
Void CsampleView: OnDraw (CDC PDC)
{
// Get icon information
IF (: ShgetfileInfo (_t (c: // program files // accessories // wordpad.exe "), 0,
&& StfileInfo, Sizeof (StfileInfo), SHGFI_ICON))
{
// Display the obtained icon information using the Drawicon interface of the device description table
PDC -> Drawicon (10, 10, stfileinfo.chicon);
}
}
Alternatively, you can also call the Extracticon function to obtain the icon information of the application, and the Drawicon function of the device description table is called display.
Void CsampleView :: OnDraw (CDC PDC)
{
HiCon Hicon = :: Extracticon (AfxgetInstanceHandle (), _ T
("C: // Program Files // Accessories // WordPad.exe"), 0);
IF (Hicon &&& HiCon! = (HICON) -1)
PDC-> Drawicon (10, 10, Hicon);
}
