Hello all,
As you all probably know I am very new to programming. I am trying to understand the terminology involved with programming. So if you all do not mind, lets use the following example as I try and explain it. Please refer to the following link:
http://msdn.microsoft.com/en-us/library/aa446675(VS.85).aspx[LINK]
GetUserObjectSecurity is a function. Its function is a member of what?
does GetUserObjectSecurity have to be included in int main() ? If not can you please explain the reasoning?
If you look at the link I provided above, on the page it has a syntax block. In the syntax block, it is refering to BOOL. Now I have seen bool and BOOL and was wondering if this is included in your source code? I read that BOOL is the older version of bool? And all bool is for, is for true/false correct?
I also read that bool is a type of int, meaning could you use bool main() ? Obviously I am confused on this. Also when you use bool, is it required to be typed out in your source, or is it implied by some <header> file? How do you properly use bool? I also read that bool uses one (byte), versus BOOL uses 32(bits). Why is this?
When using GetUserObjectSecurity, what are the usages of the parameters? Can anyone provide an example with an explanation?
Thank you all so very much for your time and effort in helping me learn C++ and to continue my academic future.
V/R

I don't quite get this. If you're asking "where" is this function located, then I would say it is within a DLL named User32.dll, and comes with a companion lib file named User32.lib (The prototype is defined in Winuser.h, which is in turn included by Windows.h). So when you link to User32.lib, you could use the function like using a function that is within your code.
rbwest86 wrote: does GetUserObjectSecurity have to be included in int main()
You don't "include" a function, you call it. You can call this function, wherever you want to, given that you've included the relevant header file and linked to the relevant library, discussed above.
rbwest86 wrote: I read that BOOL is the older version of bool? And all bool is for, is for true/false correct?
BOOL is actually int, defined like this: typedef int BOOL; (I'm not sure about the file, just right click and select go to definition.) Also, Google for "BOOL vs bool".
rbwest86 wrote: Is BOOL older version of bool?
No.
rbwest86 wrote: And all bool is for, is for true/false correct?
Yes.
rbwest86 wrote: I also read that bool uses one (byte), versus BOOL uses 32(bits). Why is this?
BOOL uses 32 bits because it *is* an integer (discussed above). bool is limited to work with true and false. But with BOOL, you could use any integer. And this can come handy, if you're returning BOOL from a function and you could:
* return -1 to indicate that the function failed
* return 1 to indicate that the function succeeded
* return 5 to indicate that the something went wrong, but the error was handled. (A file wasn't existing, but it was created and written into)
* etc.,
rbwest86 wrote: Also when you use bool, is it required to be typed out in your source, or is it implied by some file? How do you properly use bool?
bool is an in-built datatype. You do not have to include any headerfile to use it. However, to use BOOL, you may have to include the headerfile, which defines it (right click on BOOL, select go to definition. That should show you the header file)
rbwest86 wrote: When using GetUserObjectSecurity, what are the usages of the parameters? Can anyone provide an example with an explanation?
The MSDN doc page what you gave us, has an example link for the same function at the bottom. It is here[^]

HI,
can any body help me as i m trying to make a resource dll to provide multilingual support for my application, is it possible to create resource file with only string tables for different languages without adding dialog boxes to it.
Thanks in Advance

I have a dialog based application named: basicreport
and created
one dialog called: CExternalDataDlg ,
3 property page called: CImportPage, COptionPage, CConfirmPage
and 1 property sheet named: CImportPropertySheet.
inside: BOOL CBasicReportApp::InitInstance()
BOOL CBasicReportApp::InitInstance(){
......
CExternalDataDlg dlg;
m_pMainWnd = &dlg;
INT_PTR nResponse = dlg.DoModal();
if (nResponse == IDOK)
{
}
else if (nResponse == IDCANCEL)
{
}
return FALSE;
}
CExternalDataDlg displayed correctly, worked fine!
I have change above code to:
BOOL CBasicReportApp::InitInstance(){
......
CImportPropertySheet importWizardSheet(_T("Import Spreadsheet Wizard"));
CImportPage importpage;
COptionPage optionpage;
CConfirmPage confirmpage;
importWizardSheet.AddPage(&importpage);
importWizardSheet.AddPage(&optionpage);
importWizardSheet.AddPage(&confirmpage);
importWizardSheet.SetWizardMode();
m_pMainWnd = &importWizardSheet;
INT_PTR nWizardResponse = importWizardSheet.DoModal();
if(nWizardResponse == ID_WIZFINISH){
AfxMessageBox(_T("Importing..........."));
}
else if(nWizardResponse == IDCANCEL){
AfxMessageBox(_T("Cancel"));
}
else{
}
return FALSE;
}
CImportPropertySheet displayed correctly, worked fine!
but when i combinated the both above into once. It looked like
CExternalDataDlg dlg;
m_pMainWnd = &dlg;
INT_PTR nResponse = dlg.DoModal();
if (nResponse == IDOK)
{
CImportPropertySheet importWizardSheet(_T("Import Spreadsheet Wizard"));
CImportPage importpage;
COptionPage optionpage;
CConfirmPage confirmpage;
importWizardSheet.AddPage(&importpage);
importWizardSheet.AddPage(&optionpage);
importWizardSheet.AddPage(&confirmpage);
importWizardSheet.SetWizardMode();
INT_PTR nWizardResponse = importWizardSheet.DoModal();
if(nWizardResponse == ID_WIZFINISH){
AfxMessageBox(_T("Importing..........."));
}
else if(nWizardResponse == IDCANCEL){
AfxMessageBox(_T("Cancel"));
}
else{
}
}
else if (nResponse == IDCANCEL)
{
return FALSE;
}
return FALSE;
The ExternalDataDlg displayed, when i press OK button on ExternalDataDlg the CImportPropertySheet blink and the immediately disappear without any action by user.
i dont know why? Please kindly advise

Image *pIm = bm.GetThumbnailImage(size.Width, size.Height);
ImageType imt = pIm->;GetType();
Bitmap *pBm = dynamic_cast<bitmap>(pIm);</bitmap>
I need an HBITMAP object, so I need a Bitmap first.
In this code, imt will be ImageTypeBitmap,
but pBm will be NULL. What is the problem?
Though Graphcs::DrawImage can do the work, but it's better
to save a Graphcs object.

I suggest you help yourself getting helped by making things somewhat easier, such as showing formatted code (use the "code block" button) and by specifying the symptoms, i.e. why do you think something is wrong?

as per Luc's comments - define 'something' for us - what are the symptoms/error messages - can you step by step debug the program for example
we dont read minds - give us a bit more to go on - no-one (ok, almost no one, unless they are incredibly generous) is going to take code posted in that condition, attempt to compile it etc for you given your description.

arrays are zero-based, NOT one-based; so your array loops should be like :
for (x=0;x<9;x++)

ıwas complie many times but the program coming we can say read when ı execute program ısaw the window just
"access1 "
and then stop and givme error .
after that ı have to shutdown the program.
I'm stuck ı have no idea how can ı get rid of that ?
some people say give me spesific ı think this message a little bit specific .
ı have got an appointment my lecturer next week for this program .
I'm still searching to fix that but unfortunately nobody knows .

Common, ... Can't you try at least to write something understandable ? People asked you to give details about the problem you encountered and you reply that the program stop and "givme error". Which error ? Do we really need to ask 20 questions before we can get a clear description of your problem ?
Anyway, did you consider using your debugger to track the problem ?

You'll have to translate that text. In any case, why do you refuse to use the debugger? Anything short of that and you're just wasting everyone's time, including your own.

You thought wrong. When you take you car to the shop to have it serviced, do you just hand the keys to the mechanic and say, "It won't run" and expect him to know where to start looking?

So why has he not been consulted earlier?

Hi,

That's fine. Now you should study the driver documentation in order to know what you need to send on the serial line.
Have you such a documentation?

I am able to get my *->DevicePath variable to pass to CreateFile (displayed a bit below) however I am unable to get a proper handle. It seems that no matter which attributes or whatever I change to my CreateFile function, the function ALWAYS returns INVALID_HANDLE_VALUE
\\?\usb#vid_04e6&pid_5116#5&9b0a1df&0&1#{50dd5230-ba8a-11d1-bf5d-0000f805f530}
Is it that I have an improper *->DevicePath name, or is it something with my CreateFile? Or am I missing a step here? Any help would be greatly appreciated!
