The easiest way would be to compare an empty SDI application with an empty MDI application. I know that OnInitInstance() will have a few differences. As far as the frame goes, CMDIFrameWnd will be used instead of CFrameWnd. The document will use CMultiDocTemplate instead of CSingleDocTemplate.

How about CreateProcess()?

If you only have to run on WindowsXP or later, you are in luck.
Your service, after registering its service control handler function, should receive a control event of SERVICE_CONTROL_SESSIONCHANGE. This will pass a data structure with the information about what happened: log on, log off, session locked, etc.

From MSDN:"A HandlerEx function is an application-defined callback function used with the RegisterServiceCtrlHandlerEx function. A service program can use it as the control handler function of a particular service.

The LPHANDLER_FUNCTION_EX type defines a pointer to this function. HandlerEx is a placeholder for the application-defined name.

This function supersedes the Handler control handler function used with the RegisterServiceCtrlHandler function. A service can use either control handler, but the new control handler supports user-defined context data and additional extended control codes."

Also see this:"WTSSESSION_NOTIFICATION
The WTSSESSION_NOTIFICATION structure provides information about the session change notification. A service receives this structure in its HandlerEx function in response to a session change event."

Menu Item Bitmap

I like to change an ItemMenuBitmap with the CMenu::SetMenuItemBitmaps() function.
I have problem to display the correct bitmap. Usually a dot bitmap is displayed ( may be is the default bitmap of MFC ).

Below is the used code.

CBitmap bitMap ;
bitMap .LoadBitmap(IDB_BITMAP);
pPopup->SetMenuItemBitmaps(ID_MENU_ITEM1,
MF_BYCOMMAND,&bitMap, &bitMap);

Dont declare bitMap variable local . If you declare it out of the function that you wrote this code it work safe .

I wrote this code and work very well :

CBitmap m_CheckBitmap,m_UnCheckBitmap;
OnButton1()
{
ASSERT(m_CheckBitmap.LoadBitmap(IDB_BITMAP1));

// Associate bitmaps with the "Test" menu item.
CMenu* mmenu = GetMenu();
CMenu* submenu = mmenu->GetSubMenu(0);
(submenu->SetMenuItemBitmaps(ID_A_B, MF_BYCOMMAND,
&m_CheckBitmap, &m_CheckBitmap));
}

hey, guys
As we know that a commonly used PDF file maybe contains both the vector elements and raster elements.
If I want to transfer all of vetor elements to raster then what will I do?
I think that some API functions is neccessary, so who can show me them.
thanks all

You have to use a RIP (raster image processor).. There are several around... some cheap, some expensive.. some freeware. Have a look for an application called GhostScript... that'll do what you wnat to do.

hello all

im connecting to a ODBC datasource and im using

hr = cpDbCMIS->Open("DSN=CP_CMIS_CON;UID=STUD_ADMIN;PWD=STUD_ADMIN","","",-1);

to connect to it, this works fine when i already know the user name and password
but i need to connect to different databases, with different user names and passwords
which would be provided by the users, and then stored in CString variables

i want to use something like

CString CnnStr="DSN=CP_CMIS_CON;UID="+username+";PWD="+password+"";

hr = cpDbCMIS->Open(CnnStr,"","",-1);

but i cant get that to work Confused | :confused:

can ne1 help at all

Why? What is the value of CnnStr after the assignment? It should be the same as the first value you've shown being passed to Open().

but if i use

CString CnnStr="DSN=CP_CMIS_CON;UID="+simon11+";PWD="+simon12+"";
hr = cpDbCMIS->Open(CnnStr,"","",-1);

then i get a complier error

error C2664: 'Connection15::Open' : cannot convert parameter 1 from 'CString' to '_bstr_t'

if i use GermanGeorge's example

CString tmp="DSN=CP_CMIS_CON;UID="+simon11+";PWD="+simon12;
cpDbCMIS->OpenEx(tmp, CDatabase::noOdbcDialog );

then i get the compiler error

error C2039: 'OpenEx' : is not a member of '_Connection'

How about:

hr = cpDbCMIS->Open(_bstr_t((LPCTSTR) CnnStr), "", "", -1);

If I want to know the dependancies of IE patch ?how should I know?
where are these patch ids stored.
How should one come to know that a IE has patch?
