// Description:
|
|
sl@0
|
14 |
// The FontInjector DLL is a utility that allows test code to intercept any
|
|
sl@0
|
15 |
// virtual function calls to CFont or COpenFont objects. It is used to detect
|
|
sl@0
|
16 |
// possible virtual function calls to objects in the shared heap of the Font
|
|
sl@0
|
17 |
// and Bitmap Server from a client process. Currently, such detection only
|
|
sl@0
|
18 |
// works on the emulator, where code in a DLL that has been loaded by one
|
|
sl@0
|
19 |
// process can effectively be executed from any other process.
