You need to print a bmp file maybe it is some helpful to you

Thanks for the reply.

Your above code is basicaly what I am doing now, with the exeption that i am using StretchDBits, and calculating the margins.

I was wondering why this could be causing files larger than 60mb to be sent to the printer.

After a little research I have seen the error of my ways.

The problam was, I was creating a bitmap to the size of the paper in pixels. Obviously the pixel count in a print DC is substantialy higher than the of the screen. In effect of was creating a bitmap some 3000x5000 pixels and sending that to the printer.

I have now changed it to create a bitmap of (842,595) which is what my paint program creates when selecting A4 size. This has reduced the file size to under 2mb with no apparent distortion. Since I am unable to test this on a real printer, I just hope it is correct.

Hi waldermort ,

Re: How to Enable a submenu item in MDI

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.

Hello,
try this to solve it:

<br />
    // to activate an menuitem:<br />
    m_cMenu.EnableMenuItem(IDC_FILE_SAVE, MF_ENABLED);<br />
    m_cMenu.EnableMenuItem(IDC_FILE_SAVE_AS, MF_ENABLED);<br />
<br />
    // to deactivate an menuitem:<br />
    m_cMenu.EnableMenuItem(IDC_FILE_SAVE, MF_DISABLED | MF_GRAYED);<br />
    m_cMenu.EnableMenuItem(IDC_FILE_SAVE_AS, MF_DISABLED | MF_GRAYED); <br />
    // NOTE: "m_cMenu" is not a submenu, is no matter is this a submenu or not<br />
    // m_cMenu.[EnableMenuItem] takes all subitems such as popupmenu when you dropdown the menuitem<br />
    // example: MenuItem "File"->"Save" and "File"->"SaveAs" is in my sample<br />

i hope this can help you!
regards

edit subitems in listview

mukri74322-Mar-06 2:21

22-Mar-06 2:21

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:
        // your code here
    break;

    case WM_CHAR:
        // your code here
    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

COleDateTime error in VS.NET 2003 ?

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.

How to get the status of a USB printer.

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_PAGE_PUNT:

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;

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))

}
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.
