FVSHOWINFO
Contains information that the IFileViewer::Show member function uses to display a file.
typedef struct {
DWORD cbSize; // size of structure, in bytes
HWND hwndOwner; // see below
int iShow; // see below
DWORD dwFlags; // see below
RECT rect; // see below
LPUNKNOWN punkrel; // see below
OLECHAR strNewFile[MAX_PATH]; // see below
} FVSHOWINFO, *LPFVSHOWINFO;
Members
hwndOwner
Handle of the owner window. When a file viewer creates a window to display a
file, it should specify this handle as the owner of the window.
iShow
Show command. For a list of show commands, see the description of the ShowWindow function.
dwFlags
Show information flags. This member can be a combination of these values:
FVSIF_CANVIEWIT
| The file viewer can display the file.
| FVSIF_NEWFAILED
| The file viewer specified a new file to display, but no viewer could display
the file. The file viewer should either terminate or continue to display the
previous file.
| FVSIF_NEWFILE
| A drag and drop operation has dropped a file on the file viewer window. The
file viewer passes the name of the file to the shell by copying the name to strNewFile. The shell attempts to load a file viewer that can display the new file.
| FVSIF_PINNED
| A pinned window exists. A file viewer should either use the pinned window to
display the file or set a new pinned window and display the file in it.
| FVSIF_RECT
| rect contains valid data.
|
rect
Address of a RECT structure that specifies the size and position of the file viewer's window.
This member is valid only if dwFlags includes the FVSIF_RECT value.
punkrel
Address of an interface whose Release member function is called by a new file viewer to release the previous file
viewer. This member is used when a drag and drop operation drops a file on the
file viewer's window.
strNewFile
Address of a string that specifies the name of a new file to display. A file
viewer sets this member when a drag and drop operation drops a file on the file
viewer's window.
The shell uses this structure to pass information to a file viewer, and a file
viewer uses it to return information to the shell.

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 » |
