If the menu items do not have handlers ( ON_COMMAND ) they will be disabled by default.
If you want to have them enabled, either had handlers for the command or and update handlers ( ON_UPDATE_COMMAND_UI ) to enablet the menu item.

Inside your MDI MainFrame Constructor set this boolean variable to FALSE
m_bAutoMenuEnable = FALSE;

i have to create a list view where u can edit subitems.( non MFC one)
I refered the article by Mr.Zafir
http://www.codeguru.com/cpp/controls/listview/editingitemsandsubitem/article.php/c923/
i am unable to trace when the functions in the class(here: CInPlaceEdit) which is derived from the CEdit are invoked or called.
It has something like this... in the .h file
//{{AFX_MSG(CInPlaceEdit)
afx_msg void OnKillFocus(CWnd* pNewWnd);
afx_msg void OnNcDestroy();
afx_msg void OnChar(UINT nChar, UINT nRepCnt, UINT nFlags);
afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);
//}}AFX_MSG
DECLARE_MESSAGE_MAP()
in the .cpp file
BEGIN_MESSAGE_MAP(CInPlaceEdit, CEdit)
//{{AFX_MSG_MAP(CInPlaceEdit)
ON_WM_KILLFOCUS()
ON_WM_NCDESTROY()
ON_WM_CHAR()
ON_WM_CREATE()
//}}AFX_MSG_MAP
END_MESSAGE_MAP()
as this is not valid in a non MFC one .. i used something like this. in the .h file
BEGIN_MSG_MAP(CInPlaceEdit)
MESSAGE_HANDLER(WM_NCDESTROY, OnNcDestroy)
MESSAGE_HANDLER(WM_KILLFOCUS, OnKillFocus)
MESSAGE_HANDLER(WM_CHAR, OnChar)
MESSAGE_HANDLER(WM_CREATE, OnCreate)
END_MSG_MAP()
LRESULT OnNcDestroy(UINT nMsg, WPARAM wParam, LPARAM lparam, BOOL& bHandled);
LRESULT OnKillFocus(UINT nMsg, WPARAM wParam, LPARAM lparam, BOOL& bHandled);
LRESULT OnChar(UINT nMsg, WPARAM wParam, LPARAM lparam, BOOL& bHandled);
LRESULT OnCreate(UINT nMsg, WPARAM wParam, LPARAM lparam, BOOL& bHandled);
what i want to know is how to call these functions or how to invoke them or
when are they called(from where).
right now they are not been called?
i am just able to create the edit control at a particular sub item location...
Plz Plz help me ragarding this..
Thank in advance.

I think you are going bout this the wrong way. In non-MFC you don't need to create a seperate function for windows message, you simply need to handle them in the parent window of your control.
Normally you would use
switch (message) {
case WM_KILLFOCUS:
break;
case WM_CHAR:
break;
}
For list views you should consult MSDN for exactly what messages are sent and where to trap them (for list views usually they are in the form of a WM_NOTIFY). there are also some good articles on here about how to handle windows messages.

Hi friends,
i want to develop an application wherein i need to send ".txt"(size may vary aroung 1MB) files across the network(LAN) from one computer to another. So i want to know which will be the simplest and easiest way to do it? will it be sockets or TCP/IP or DCOM(i know this thing is very tough..).
since performance(speed) is not so important i'd like to know the simplest method to do this.
Thanks and regards,
Rajeev

Hello, i suggest you consider the TCP/IP sockets for your application. Good luck.

You could always do the copy yourself to a UNC sharename on the target computer.
onwards and upwards...

Hi,
Recently I wrote simple code like that:
//
COleDateTime dt(2006,02,30,1,1,1);
if (dt.GetStatus() == COleDateTime::valid) {
AfxMessageBox("valid");
}
else {
AfxMessageBox("NOT valid");
}
///
It shows message box "valid" in VS.NET 2003 ! Am I crazy ? Or sth is wrong ?
It shows message box "NOT valid" in VS 6.0.
Best regards,
Irek Olchawski.

You might find this[^] useful.
Thanks for the heads-up  . The apps that I write uses this class a lot and could, in theory, be severly affected by this.

hi,
I needed a small help regarding the code which i have written in VC++ to get the status of a printer like ''PRINTER_STATUS_NO_TONER", "PRINTER_STATUS_PAPER_JAM" etc..
I have written the following code:
char szPrinter[255];
memset(szPrinter,'\0',255);
strcpy(szPrinter,m_szPrinterName.operator LPCTSTR());
BOOL bSuccess = FALSE;
HANDLE hPrinter = NULL;
PRINTER_DEFAULTS *lpDefaults = NULL;
BOOL bOpen = ::OpenPrinter(szPrinter, &hPrinter, lpDefaults);
DWORD dwBytesReturned;
DWORD dwBytesNeeded;
GetPrinter(hPrinter, 2, NULL, 0, &dwBytesNeeded);
PRINTER_INFO_2 *pPrinterInfo = (PRINTER_INFO_2*)GlobalAlloc(GPTR,dwBytesNeeded);
bSuccess = ::GetPrinter(hPrinter, 2, (LPBYTE)pPrinterInfo,dwBytesNeeded, &dwBytesReturned);
uint32 dwStatusID = 0;
switch(pPrinterInfo->Status)
{
case PRINTER_STATUS_BUSY:
dwStatusID = ID_STAT_PRN_BUSY;
bSuccess = TRUE;
break;
case PRINTER_STATUS_DOOR_OPEN:
dwStatusID = ID_STAT_PRN_DOOR_OPEN;
bSuccess = TRUE;
break;
case PRINTER_STATUS_ERROR:
dwStatusID = ID_STAT_PRN_ERROR;
bSuccess = FALSE;
break;
case PRINTER_STATUS_INITIALIZING:
dwStatusID = ID_STAT_PRN_INITIALIZING;

break;
case PRINTER_STATUS_IO_ACTIVE:
dwStatusID = ID_STAT_PRN_IO_ACTIVE;

dwStatusID = ID_STAT_PRN_OUT_OF_MEMORY;
bSuccess = FALSE;
break;
case PRINTER_STATUS_OUTPUT_BIN_FULL:
dwStatusID = ID_STAT_PRN_OUTPUT_BIN_FULL;
bSuccess = TRUE;
break;
case PRINTER_STATUS_PAGE_PUNT:
dwStatusID = ID_STAT_PRN_PAGE_PUNT;
bSuccess = FALSE;
break;
case PRINTER_STATUS_PAPER_JAM:
dwStatusID = ID_STAT_PRN_PAPER_JAM;
bSuccess = FALSE;
break;
case PRINTER_STATUS_PAPER_OUT:
dwStatusID = ID_STAT_PRN_PAPER_OUT;
bSuccess = FALSE;
break;
case PRINTER_STATUS_PAPER_PROBLEM:
dwStatusID = ID_STAT_PRN_PAPER_PROBLEM;
bSuccess = FALSE;
break;
case PRINTER_STATUS_PAUSED:
dwStatusID = ID_STAT_PRN_PAUSED;
bSuccess = TRUE;
break;
case PRINTER_STATUS_PENDING_DELETION:
dwStatusID = ID_STAT_PRN_PENDING_DELETION;
bSuccess = FALSE;
break;
case PRINTER_STATUS_POWER_SAVE:

bSuccess = TRUE;
break;
case PRINTER_STATUS_PRINTING:
dwStatusID = ID_STAT_PRN_PRINTING;
bSuccess = TRUE;
break;
case PRINTER_STATUS_PROCESSING:
dwStatusID = ID_STAT_PRN_PROCESSING;
bSuccess = TRUE;
break;
case PRINTER_STATUS_SERVER_UNKNOWN:
dwStatusID = ID_STAT_PRN_SERVER_UNKNOWN;
bSuccess = FALSE;
break;
case PRINTER_STATUS_TONER_LOW:
dwStatusID = ID_STAT_PRN_TONER_LOW;
bSuccess = TRUE;
break;
case PRINTER_STATUS_USER_INTERVENTION:
dwStatusID = ID_STAT_PRN_USER_INTERVENTION;
bSuccess = FALSE;
break;
case PRINTER_STATUS_WAITING:
dwStatusID = ID_STAT_PRN_WAITING;
bSuccess = TRUE;
break;
case PRINTER_STATUS_WARMING_UP:
dwStatusID = ID_STAT_PRN_WARMING_UP;
bSuccess = TRUE;
break;
case 0:
bSuccess = TRUE;
break;
default:
dwStatusID = PRINTER_STATUS_SERVER_UNKNOWN;
bSuccess = FALSE;
break;
}
The above code works fine for a parallel port network printer,but the "pPrinterInfo->Status" parameter returns "0" for a local USB printer.
Can anyone kindly tell me what may be the problem.

Hi,
CMenu* pMenu = GetMenu();
ASSERT (pMenu != NULL);
for(int i=0;i< (int)pMenu->GetMenuItemCount();i++)
{
CMenu* pActionMenu = pMenu->GetSubMenu(i);
ASSERT (pActionMenu != NULL);
int nMenuItemCount = pActionMenu->GetMenuItemCount();
int nTemp = nMenuItemCount-1 ;
nMenuItemCount=nMenuItemCount-1;
while (nMenuItemCount >= 0)
{
if(!(i==0 && nMenuItemCount==nTemp))
{
pActionMenu->RemoveMenu(nMenuItemCount, MF_BYPOSITION);
//pActionMenu->EnableMenuItem( pActionMenu->GetMenuItemID
(nMenuItemCount) ,MF_BYCOMMAND|MF_DISABLED);
}
nMenuItemCount=nMenuItemCount-1;
}
}
Requirement : Disabling all menu items
I have used the above code snippet to removing Menu items in my application.
But when i attempt to use EnableMenuItem for disabling than removing it fails.
Can any one show some light on this?

RemoveMenu: Deletes a menu item with an associated pop-up menu from the menu.
Try using same function i.e EnableMenuItem for enabling & diabling the menu items.

Ashok.

Use ON_UPDATE_COMMAND_UI.

I can use ON_UPDATE_COMMAND_UI if i need to disable a single menu item
My requirement is to disable all menus in a single shot,How can this be done.
Thanks
for thendral

Hi, I think that the only solutions is to disable each item of your menu. There isn't other way to make this. Sorry and good coding!

|

You can use ON_UPDATE_COMMAND_UI_RANGE. There are certain limitations too.

From Code Project articles i have coded a C++ DLL to be used as a global hook for C# projects. I have been successful in getting a global keyboard hook working. But when i try the same with a mouse hook, computer CPU goes to 100% and C# app gets a million messages that say the same thing. I am not the greatest C++ programmer. Am i missing something here? I think i have all the code parts needed?
Below is the code i am using (40+ lines):
#include "stdafx.h"
#include "hookdll.h"
#pragma data_seg("SHARED")
HHOOK m_mouseHook = NULL;
HWND m_hHookClient = NULL;
#pragma data_seg()
#pragma comment(linker, "/SECTION:SHARED,RWS") // linker directive
HINSTANCE m_hHookDLL = NULL;
const int GH_MOUSEOTHER = WM_USER + 4099;
BOOL APIENTRY DllMain(
HANDLE hInstance,
DWORD callReason,
LPVOID reserved)
{
switch (callReason)
{
case DLL_PROCESS_ATTACH:
m_hHookDLL = (HINSTANCE)hInstance;
break;
case DLL_THREAD_ATTACH:
case DLL_THREAD_DETACH:
case DLL_PROCESS_DETACH:
break;
}
return TRUE;
}
extern "C" __declspec(dllexport) void InstallHook(HWND hWnd)
{
m_mouseHook = NULL;
m_hHookClient = hWnd;
// set mouse hook
m_mouseHook = SetWindowsHookEx(WH_MOUSE, (HOOKPROC)MouseHookProc,
m_hHookDLL, NULL);
}
extern "C" __declspec(dllexport) void RemoveHook()
{
UnhookWindowsHookEx(m_mouseHook);
}
LRESULT CALLBACK MouseHookProc(
int nCode,
WPARAM wParam,
LPARAM lParam)
{
if (nCode >= 0)
{
PostMessage(m_hHookClient, GH_MOUSEOTHER, wParam, lParam);
}
// pass control to next hook in the hook chain
return CallNextHookEx(NULL, nCode, wParam, lParam);
}

Hi,
is it possible for me to code a program in c++ to gather all URLs contained in a website/webpage?
or if not does anyone have a code to find URLs in a text file?
Does anyone have a sample code or a link that may give me information about this?
Your help will be appreciated. Thanks in advance

Use the following regular expression:
"<\\s*A\\s+[^>]*href\\s*=\\s*\"([^\"]*)\""
I've taken it from an example of boost regex library.

Thanks, but can u show me a more precise code?
