Hello all.
How can I retrive the name of all files that are in a specified directory?
If the soulition could be done with standard C/C++, it would be better than using Windows API or other. But any idea will help.
Thanks a lot.
Kith.

Under windows you can use the FindFirstFile and FindNext functions to do this. If you need a platform independant system you might want to look at boost::filesystem.
MSDN Example
boost::filesystem

If you can dream - and not make dreams your master;
If you can think - and not make thoughts your aim;

Hi,
I have an MFC SDI application and in the view I have a CListCtrl.
Based on the size of the list, I need to enable/ disable some menu options. For example, if the list has no elements, then the option in Edit> Remove should be disabled. How do I do that?
I don't seem to have handles to the menu items I want to disable in <application>View.cpp.
Thanks in advance.
Help wanted!

Is there an example of simple notepad program? Nothing fancy. I just need example on how to do File -> New, how to display opened file on screen, and how to take what's type on the screen save into text file. Without using Dialog.
|
|
|
|
|
MSDN come with that sample. Look at the sample folder

Where? Using Visual Studio 6.0 here. If you are talking about .net 2002 version I downloaded that one but it's wordpad style and too complex. I need something very simple
|
|
|
|
|
If you are using VS6.0, it is very simple to have a text editor. Just create a project by wizard and choose CEditView as base class for view. Is that you needed?
|
|
|
|
|
But in that, File -> New doesn't work, File -> Open doesn't open the text file, and File -> Save doesn't save the content.

Hi,
I'm having troubles processing my user messages so I think I'm leaving some code line.
I do this:
#define WM_ICON_NOTIFY WM_APP+10
...
int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,LPSTR lpCmdLine, int nCmdShow)
{
...
while (GetMessage(&msg, NULL, 0, 0))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
...
}
...
inicialize the structure NOTIFYICONDATA:
...
icon.uCallbackMessage = WM_ICON_NOTIFY;
...
and process the messages:
LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
{
...
switch (message)
{
case WM_ICON_NOTIFY:
my action
.....
but anything I do in case WM_ICON_NOTIFY there's not response, so I'm sure the program doesn't receive the messages when click a mouse button over the icon, for example.
What i'm doing wrong?
Thanks!

instead of using WM_APP use WM_USER
and try sending Dummy message to your application,to se wheather you are receiving message or not using
PostMessage or SendMessage Apis
Really these apis are very Easy and Whole window system depend on it,REALLY

I've tried with PostMessage and SendMessage and nothing, app doesn't receive anything.
With WM_APP or WM_USERS occurs the same.
One question, in Project Settings i'm using MFC in a static library because with Not MFC I have problems to linking:
nafxcwd.lib(thrdcore.obj) : error LNK2001: unresolved external symbol __endthreadex
nafxcwd.lib(thrdcore.obj) : error LNK2001: unresolved external symbol __beginthreadex
If I use MFC in a static library i have to do a MESSAGE_MAP? Will it be this the problem?
I haven't an own class so i don't know how to do a message map.
--Modify-- I've modified the program to NOT use MFC ant continues the trouble

I got it!!!!!!
I've created another invisible window that it will be POPUP for the icon, so the app message from the taskbar are processed well.
Ufffff.
ThatsAlok, thank you very much for your help in all my threads, you help me a lot, I'm newbie and i'm lose easily 
Thanks

I have a UI basically consisting of a CWnd (the Bad Window)as a child of a CTabCtrl as a child of a CWnd ( a placeholder ) inside a docking window.
When creating the hierarchy, every UI window is created and resized properly up to The Bad Window; upon Spy++ing it, I find that its size and position is (0,0,0,0)
I suspect that at one level, when I do a MoveWindow on a UI, it does not propagate the WM_SIZE because the size is the same.
I have something like in an OnSize Handler:
CRect rect;
GetClientRect( rect );
rect.DeflateRect( 2, 2, 2, 2 );
m_pController->MoveWindow( rect );
I suspect the size of m_pController is the same as rect and does not trigger a WM_SIZE.
When I manually resize the docking window, all is fixed and resized nicelly.
Is there a way to force a WM_SIZE to be triggered ? or maybe I'm missing some obvious thing ?
Can SetWindowPos be used to help fix the problem ? ( I will try that ... )
Thanks.

Hi,
I want to change the dialog box size so that it fits my computer screen without having any horizontal or vertocal scroll bars. Is it possible to do this by changing the property of the dialog box. Its just the one time change the user is not going to alter its size.
please help me out. I read a few articles where i need to include new class. can anyone please help me on this

Use GetSystemMetrics() to get the current resolution. Then use SetWindowPos() or MoveWindow() to change the size.

If you want to set the size of the dialog, do so by calling SetWindowPos() or MoveWindow() in the dialog's OnInitDialog() method.

Hello, everybody
I have a problem with the GetPrinter call. I use the following code to get the printer info:
// The printer Information (PRINTER_INFO_2)
// is pointed to by m_pPrinterInfo
BOOL CAutoApp::GetPrinterInfo()
{
HANDLE hPrinter = GetPrinterHandle( (char*)((LPCTSTR)(m_printer)) );
if ( hPrinter == NULL ) return FALSE;
// Release previous information
if ( m_pPrinterInfo != NULL )
{
free(m_pPrinterInfo);
m_pPrinterInfo = NULL;
}
DWORD cByteNeeded, cByteUsed;
// Get the buffer size needed
if (!GetPrinter(hPrinter, 2, NULL, 0, &cByteNeeded))
{
if (GetLastError() != ERROR_INSUFFICIENT_BUFFER)
{
_stprintf( m_szLog, "Error code: %u\r\n", GetLastError() );
PrintFileLog::WriteLog( m_szLog ); // winerror.h
PrintFileLog::WriteLog( "Failure to get the printer Info buffer size" );
CloseHandle(hPrinter);
return FALSE;
}
}
m_pPrinterInfo = (PRINTER_INFO_2 *)malloc(cByteNeeded);
if ( m_pPrinterInfo == NULL )
{
// Failure to allocate memory
PrintFileLog::WriteLog( "Failure to allocate memory for the printer Info" );
CloseHandle(hPrinter);
return FALSE;
}
// Get the printer information
if (!GetPrinter(hPrinter,
2,
(LPBYTE)m_pPrinterInfo,
cByteNeeded,
&cByteUsed))
{
// Failure to access the printer
PrintFileLog::WriteLog( "Failure to obtain the printer Info" );
CloseHandle(hPrinter);
free(m_pPrinterInfo);
m_pPrinterInfo = NULL;
return FALSE;
}
CloseHandle(hPrinter);
return TRUE;
} // GetPrinterInfo
When I apply the method to my local printer I get the number of jobs submitted to the printer. However, when I try to get the number of print jobs for a network printer I always get it = 0.
I use the testing procedure
void CAutoApp::printerJobs()
{
// begin testing
int cnt = 0;
bool bJobFound = false;
do
{
if ( GetPrinterInfo() )
{
if ( m_pPrinterInfo->cJobs > 0 )
{
bJobFound = true;
break;
}
}
if ( !bJobFound )
{
Sleep( 5 ); cnt++;
}
} while ( !bJobFound && cnt < 10000 ); // 50 secs wait
if ( bJobFound )
MessageBox(NULL, "Print Job Found!", "Test", MB_OK);
else
MessageBox(NULL, "Print Job Not Found...", "Test", MB_OK);
return;
} // printerJobs
to capture the event (m_pPrinterInfo->cJobs > 0).
I don't know why it works differently for both printers. My access rights to both printers are 'Administrator access rigths' (Print, Manage Printers, Manage Documents, Special Permissions).
I'd appreciate any hint.
Thank you.

hello
i have a data base in prolog and i want to transfer it to excell and make some transformation ,i would like to know if there some API or command who can help me in this work?
|
|
|
|
|
My first question would be is this sort of thing even possible (i.e., exporting the Prolog database to something that Excel can understand)? If it can be done manually, chances are there's a way to do it via code.

i could transfer the prolog database to text file ,and now i am looking to transfer it to excel file .
|
|
|
|

That'll probably work, but you need to make sure that the format of the text file is understandable by Excel. To verify this, export the Prolog database to a text file and try to open the file via Excel. It will ask you about the delimeters used in the file. If you can successfully open the file via Excel, then you can do the same thing with code.
