Hi,

I have some DOS legacy applications ( No code available for this)
accessing windows network file (say, test.dat) to write data. Many of
these application write data in this file exclusively. A windows
application (MFC, source available) reads this test.dat file. To read
this file, I have used ReadFile(..) function. This function sometimes
return success and if byte length is checked it is exact number of
bytes requested but data is all NULLs. This problem i found when i
try
to read repeatedly last record before the end of file while other
applications are writing records into it.

for example, File Lenght=2000/Current position=1900, at this position
it is showing this behaviour. record lenght is 100bytes.

Can anybody help me with your ideas for this behaviour, please?

Thanks in advance

Sorry, this is the first day I've been trying to understand Vista security,
so I'm probably going to ask a lot of questions using the wrong jargon
(grin) ...

The situation is this. I have an MFC application under Visual C++ 6.
Porting it to a newer version of Visual Studio is not an option, I tried and
it required so many changes to the app to get it to compile that the QA
department (correctly) said these changes would require a complete QA cycle
of every single feature, and we don't have time for that right now.

The program is composed of several EXEs, and one of the feature it has is
automatic updating, where it downloads a new EXE from our web site (with
appropriate security) and then overwrites the installed EXE. Under XP this
works fine (obviously no EXE tries to overwrite itself).

Vista of course assumes my application is a virus and puts the kibosh on the
whole automatic update thing.

As I've been reading up on this, I'm wondering if I need to create a
manifest. But then I'm not sure what to put in it ... 95%% of the time, the
program won't be automatically updating itself, so I don't want the
obnoxious Vista "Oh my God somebody is trying to run an application! Shall
I kill it?" message popping up every time users run my application.

My code seems to play the mp3 for a second, but then it scatters and
stops. When I insert a Sleep(3) at commented part, it works.
What's wrong here?

(fully featured working example ahead, just replace the MP3_FILE name)

### -start code- ###

#include
#include
#pragma comment(lib, "VFW32.lib")

#define MP3_FILE "C:\\music.mp3"

HINSTANCE hInst; // Aktuelle Instanz

LRESULT CALLBACK __WndProc_(HWND hWnd, UINT message, WPARAM wParam,
LPARAM lParam)
{
switch (message)
{
case WM_ERASEBKGND:
return 1;
case WM_CLOSE:
DestroyWindow(hWnd);
PostQuitMessage(0);...

Hi,

I am printing a local html file using ShellExecuteEx.It works fine as
long as Internet Explorer is the default browser. But when Firefox is
set as the default browser i get a message saying "This file does not
have a program associated with it to perform this action. Create an
association in folder options control panel". What can i do to solve
this problem?

Thanks,
