Hi,
I am doing a fopen and fwrite,
TCHAR *szFileName = tmpnam(NULL);
FILE *pfBmpFile = fopen( szFileName, "wb" );
fwrite( lbbuddy_data, sizeof(unsigned char), __bmp_size, pfBmpFile );
fclose( pfBmpFile );
There is no problem when we create our application users as administrators on the workstation
but in this case they can not be Administrators because of security risks. So whenever i use a Non-Admin users the application crashes.
Does someone have suggestion on how to go about other than giving administrator access?

it crashes ? you should check the return from fopen before using it in fwrite/fclose.
you'll probably have better luck if you create your temp file in the system temp folder. use SHGetSpecialFolderLocation to get the path.

Does tmpnam() return a path that non-administrators have access to?

Last time I checked, all files had names.

See the docs for the OPENFILENAME structure Flags member: "If you want the old-style user
interface, omit the OFN_EXPLORER flag and provide a replacement old-style template or hook
procedure. If you want the old style but do not need a custom template or hook procedure, simply
provide a hook procedure that always returns FALSE."
The GetOpenFileName()[^] docs explain how to add the hookproc.

Hi,
WIN 32 application crashes while calling a MFC DLL export function, which creates a dialog box using CDialogBox::Create().
What will be the reason?
One more doubt..How can I add MFC support to a WIN 32 Aplication?
Thankx In Advance...
|

If the MFC dialog is created on the main application thread then the main application thread needs
to be an MFC UI thread. That means your application needs to be an MFC app.
I think the easiest way to convert a Win32 app to MFC would be to create a new MFC project with
the app wizard. MFC provides the WinMain() function so...
From the Win32 code, take application-wide initialization code and put it in the new app class'
InitInstance() override. Cleanup code goes to an ExitInstance() override.
The Win32 app's main window message handling can be moved to MFC window message-map style
handlers. MFC provides the message loop.
Hope that helps get you started.

what is the difference between const and volatile ?
and which can be the cases we use them?
Thank you

In brief:
const is a contract between the developer and the compiler: the developer promises not to modify the const-declared identifier and if he/she violates that contract the compiler generates an error.
volatile is used as an instruction to the compiler that the volatile-declared identifier may be modified in the background. The compiler must not optimize and cache it in a register; its memory location has to be read each time the value is requested.

Hi,
const is to say the programm that the value in this variable should not change or be modified. One easy example to use it is when you use a function e.g. SearchObject (const CString szName, const int nID)
here I'm telling that these szName and nID may not being changed inside the run of the function.
About volatile... I can't tell you more than the MSDN help says, I have never used it.
volatile Member data is loaded from memory each time it is accessed; disables certain optimizations.

If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?

Help !!!!!!!!!!!!!!
1. I use C&WinAPI
2. to show a dialog to select file, but you cannot manipulate it
my imagine :
1. use openfile dialog and hide the right key menu
2. i know a dialog in VB, right of the dialog is a editbox show directory list, when you select any folder in that, the left side show a file list of that folder, but it is ocx, how can i invoke it?
so, how can i do for each way. and are there any other simplest way ?
