Im not sure do you need to FindFirstFile/FindNextFile? for show files
|

If your names are very predictable, how about something like:
...
CString s;
CFile f;
for (i = 0; i < 3; i++)
{
for (j = 0; ; j++)
{
s.Format ("c:\\subfolder%i\\folder%i\\blah.file", i, j);
if (!f.Open (s, ..., CFile::modeRead, ...))
break;
f.Read (stuff);
DoSomething (stuff);
f.Close ();
}
}
?
Check parameters for yourself - I know CFile::Open has not been done correctly.
If your subfolders have more random names, then you're going to have to use FindFirstFile / FindNextFile. It will be a bit harder, but not lots.

Here the SaveDC is returning 0.

In what cases SaveDc returns 0?

Hi,
I have a static CString variable declared in the dll.
static CString strUserName;
After which i make some modification to this CString inside the file. Now, I want to export this value.
However in the .def file of the dll, in EXPORTS i mention only the variable name.
EXPORTS
; Explicit exports can go here
strUserName
But i am getting linker error.
Linking...
AppProject.def: error LNK2001: unresolved external symbol strUserName
Kindly help

Remove the static keyword from declaration. If the varaible is global, then there is no need of static isnt it?

I suspect you also need to declare in the CPP file that the variable will be exported, using __declspec(dllexport).
But I've never actually exported a variable. Always a class, or a function which can modify or retrieve that variable. This gives me room at a later date to change how I work on the variable. Does it exist in the DLL? Do I interrogate some other resource (ie a DCOM object) for it, etc. It gives me more flexibility. Just a style recomendation, not a RULE.

The solution resides in your query itself. See GetSystemTime().
Somethings seem HARD to do, until we know how to do them.

You're not using the mutithreaded libraries.
- Select "Projects"->"Settings..." from the menu.
- Select the "C++" tab.
- Select "Code Generation" from the "Category" combo.
- In the "Use run-time library" combo select a multithreaded one.

I try to resize my CFrameWnd, but it doesn't work.
Can anyone tell me the reason, thanks
void CMyApp::OnAppAbout()
{
//here I want to resize and draw my framw window
SendMessage(AfxGetMainWnd()->m_hWnd, WM_SIZE, SIZE_RESTORED, MAKELPARAM(50, 50));
AfxGetMainWnd()->ShowWindow(SW_SHOW);
AfxGetMainWnd()->UpdateWindow();
}
|
|
|
|
|
SetWindowPos(AfxGetMainWnd()->m_hWnd,NULL,0,0,50,50,SWP_SHOWWINDOW);
|
|
|
|
|
Thank you for your advise.
If I call SetWindowPos, it indeed does work.
However, I feel very strange about why WM_SIZE message doesn't do any effect.
Won't it redraw the frame after I resize it?
