I am trying to retrieve the file summary information but keep receiving File not found. I have tried this on two different boxes. Can anyone suggest a reason for the failure? Can we agree the file is where I say it is? 
Thanks so much in advance

Can you first check what PathFileExists returns?

I am trying to use the wavetables in a sound card in order to play a number of overlapping WAV files.
I'm trying to avoid getting locked into a particular manufacturer so does anyone know of a gneral purpose library ?
Thanks.

Have you considered using DirectSound? It will happily play simultaneous WAV files.

Don't type when you have the flu, all you have to do is cough at the wrong moment.
I would prefer to use wave tables as that would allow more simultaneous sounds which could be useful.

how can I save a stuct whit Cfile
here is my code but id does not work :
struct naslovniki
{
CString ime1;
CString naslov1;
CString posta1;
CString drzava1;
CString naziv1;
CString skupina;
};
CFile f;
f.Open("hasek.has",CFile::modeWrite|CFile::typeBinary);
naslovniki x;
x.ime1=m_ime;
x.naslov1=m_naslov;
x.drzava1=m_drzava;
x.posta1=m_posta;
x.naziv1=m_naziv;
x.skupina;
f.Write(&x,sizeof(naslovnik));///this is the porblem
f.close();
///---there is no hope for you---\\\

I bet it does work, it just is not doing what you are expecting.
If you were to TRACE("Size of my data is %u bytes.\r\n", sizeof(naslovniki)); I bet your number would be close to 24, and it would not change depending upon what text your CStrings contain. Now, why is this? Because when you write out sizeof(naslovniki) you are only writing out the contents of the CString class, not its data. In order to write out the text of the CString (unless you are using CArhive), you have to process the data yourself, writing perhaps the length of the text followed by the contents of the text itself.

Had you serialized naslovniki instead of using Write(), it would have worked.

Hi everyone!
Thanks for the reply about running an exe directly in memory!

Hi everybody. Does anybody know why a Visual Basic Application doesn't respond to the WM_PRINT messages that I send from Visual C++? I got a serious problem with this because I'm trying to get in a bitmap the contents of a Visual Basic window even if that window is not currently on screen.
I am thinking that maybe I can insert some Visual C++ hook or subclass in the VB window and somehow determine it to answer to the WM_PRINT message. But the problem is that VB windows don't have an OnPaint event........ so I'm kind of stuck.
Thanks for reading this : ).

I am using MDI Architecture for my application.
I have the MainFrame Window within which I can create mulitple child windows.
My issue is that I am selecting a color from a dialog box.
When I click the apply button I want to invalidate all the child windows behind the dialog box so that the selected color is applied to the child windows even when the dialog box is visible in the foreground.
I used the following code but it throws a memory exception.
void CMyPropertySheet::OnApply()
{
CDC *pDC;
try
{
GetActivePage()->UpdateData(TRUE);
pDC = this->GetDC();
((CMyApplnView*)AfxGetApp())->OnDraw(pDC);
// ((CMyApplnView*)AfxGetApp())->Invalidate(FALSE);
}
catch(...)
{
AfxMessageBox(" Exception during OnApply");
}
}
I tried calling the Invalidate function of the View class as in the code above but the memory exception is still comming.Can anyone let me know what is the problem here.

For updating all the child windows i used the foll. code But it updates only the topmost window.
pMainWnd = (CMDIFrameWnd *)AfxGetMainWnd();
CMDIChildWnd *pActiveWnd = (CMDIChildWnd *)pMainWnd->MDIGetActive();
CKolOSDBuilderDoc* pDoc = (CKolOSDBuilderDoc*)pActiveWnd->GetActiveDocument();
if(pDoc)
{
pDoc->UpdateAllViews(NULL);
}

Try that
AfxGetApp()->GetMainWnd()->RedrawWindow(NULL, NULL, RDW_INVALIDATE|RDW_ALLCHILDREN|RDW_UPDATENOW);

Is there a "serious" implementation of a MRSW-Lock available?
(I *think* a MRSW lock should do whatI need: I have a map with frequent concurrent reads and rare writes, contention during reads should be very low.)

If you can write the data atomically, then you shouldn't need a lock for the readers. If you can't then this[^] might help.

I guess I can't update a std::map atomically 
But the link looks good.

Hi everybody,
I have a question .How can i print out the source code of my program, after i launch the program.
For example i run the program and it prints out on screen it's own source code ???
Thanks in advance

Use OpenProcess, VirtualQueryEx, and ReadProcessMemory to access the memory. you are probably only interested int he parts of memory marked as MEM_IMAGE, as that contaisn the code. the other parts are other data.
Pass all this data to the disassembler, which will print out the assembly language

alternativly just have the source included in a text file with your program and just have it print it like any other text file.
|
|
|
|

One thing you have to realise is that the program has no idea what it's source code is, you will need to embed the source code as you would any other string, and then you can display it the same as you would any other string.

Not possible, unless you are storing the code as part of the string table resource. The compiler turns the source code into an object file. In turn, the linker turns the object file into an executable. See here.

I would like my program to run at set times (for example, every minute at the start of the minute, or every 30 seconds, at either the start of the minute or :30). What is the best way to do this. I dont want to use just "Sleep(6000)" or something like that, because after a few runs, it wont be starting at exactly minute:00. How can I solve this problem??
Thank you

Sleep for 1 second then when it wakes up look at the system time and see if you want the program to run.
Look at CTime class members.
