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;
bSuccess = TRUE;
break;
case PRINTER_STATUS_IO_ACTIVE:
dwStatusID = ID_STAT_PRN_IO_ACTIVE;
bSuccess = TRUE;
break;
case PRINTER_STATUS_MANUAL_FEED:
dwStatusID = ID_STAT_PRN_MANUAL_FEED;
bSuccess = TRUE;
break;
case PRINTER_STATUS_NO_TONER:
dwStatusID = ID_STAT_PRN_NO_TONER;
bSuccess = FALSE;
break;
case PRINTER_STATUS_NOT_AVAILABLE:
dwStatusID = ID_STAT_PRN_NOT_AVAILABLE;
bSuccess = FALSE;
break;
case PRINTER_STATUS_OFFLINE:
dwStatusID = ID_STAT_PRN_OFFLINE;
bSuccess = TRUE;
break;
case PRINTER_STATUS_OUT_OF_MEMORY:
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:
dwStatusID = ID_STAT_PRN_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.

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?
|
|
|
|
|
If you haven't already done so, download the boost library. The regex library has an example ("regex_split_example_2.cpp"), that scans a file and returns a list of the URLs.

maybe it is some helpful to you
...
HDC m_dcPrinter=CreateCompatibleDC(CreateDC(m_Printer->pDriverName,

PrintDlg(&pd);
hBitmap=LoadBitmap or LoadImage
SelectObject(m_dcPrinter,hBitmap);
StartDoc (pd.hDC, &di);
StartPage (pd.hDC);

You are not making any sense, rephrase the question.

Of course you can use DLL with VC++.

Hi Everyone,
How can we write the commandline instructions in VC++? For example, i want to copy Excel file from one location to another location in another place(LAN). I have a copy button in my dialog. When i press the copy button, the excel file should be copied over to another location. Is it possible to do so?
Thanks in Advance.
Chetan.

system() if you directly use DOS commands.
otherwise, use CopyFile()
