基本内容

[]

Lib "gdi32" Alias "CreateICA" (ByVal lpDriverName As String, ByVal lpDeviceName As String, ByVal lpOutput As String, lpInitData As DEVMODE) As Long

C++:

HDC CreateIC( _In_ LPCTSTR lpszDriver, _In_ LPCTSTR lpszDevice, LPCTSTR lpszOutput, _In_ constDEVMODE *lpdvmInit );

[说明]

为专用设备创建一个信息场景。信息场景可用来快速获取某设备的信息而无须创建设备场景这样的 系统开销。它可作为 参数传递给GetDeviceCaps一类的 信息函数以替代设备场景参数

[From MSDN :]

The CreateICfunction creates an information context for the specified device. The information context provides a fast way to get information about the device without creating a device context (DC). However, GDI drawing functions cannot accept a handle to an information context.
