EnhMetaFileProc
The EnhMetaFileProc function is an application-defined callback function that processes
enhanced-format metafile records. This function is called by the EnumEnhMetaFile function.
int CALLBACK EnhMetaFileProc(
HDC hDC,
| // handle to device context
| HANDLETABLE FAR *lpHTable,
| // pointer to metafile handle table
| ENHMETARECORD FAR *lpEMFR,
| // pointer to metafile record
| int nObj,
| // count of objects
| LPARAM lpData
| // pointer to optional data
| );
|
|
Parameters
hDC
Identifies the device context passed to EnumEnhMetaFile.
lpHTable
Points to a table of handles associated with the graphics objects (pens,
brushes, and so on) in the metafile. The first entry contains the enhanced-metafile
handle.
lpEMFR
Points to one of the records in the metafile. This record should not be
modified. (If modification is necessary, it should be performed on a copy of the
record.)
nObj
Specifies the number of objects with associated handles in the handle table.
lpData
Points to any application-supplied data.
Return Values
This function must return a nonzero value to continue enumeration; to stop
enumeration, it must return zero.
Remarks
An application must register the callback function by passing its address to
the EnumEnhMetaFile function.
EnhMetaFileProc is a placeholder for the application-supplied function name.

Nostalgia .Net |

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
