Have you somehow told the printer to print from a manual source rather than an actual tray? What does the call to OpenPrinter() look like?

Hello everybody,

I have to write a program that generates some scripts that execute something in case of certain events.
The program must provide a visual interface from wich the user can pick available events and possible actions. The script language is not specified so I'm thinking of generating logicals relations between events and actions, like:

If Event1 AND Event2 OR Event3... Then Action1 AND Action2 AND...

From theese relations a specialized module would generate the script.
I need a way of expressing this kind of logical expressions. I don't want to reinvent the wheel Smile | :)

so I would want to use an existing language. I also need the possibility to express time, for example a timeout can be considered an event or an action can be executed for a certain amount of time.
Any ideeas?

Thanks,
Marius

I think what you need is to show the tooltips on the controls of the dialog?
Right?
Use CToolTipCtrl.

Somethings seem HARD to do, until we know how to do them.

Not entirely. The "balloon" message is displayed regardless of the mouse's position. It is displayed only when the password control has focus.

Adding tooltip is simple. Just google for it...

OnFocusing the edit box get the key state using GetKeyState(VK_CAPITAL).
The retun value will be 1 if CAPSLOCK is on see detailed return values below.

. If the high-order bit is 1, the key is down; otherwise, it is up.
. If the low-order bit is 1, the key is toggled. A key, such as the CAPS LOCK key, is toggled if it is turned on. The key is off and untoggled if the low-order bit is 0. A toggle key's indicator light (if any) on the keyboard will be on when the key is toggled, and off when the key is untoggled.

Check MSDN for more information

ON_EN_SETFOCUS handler of the dialog class

e.g

BEG_MESSAGE_MAP()
ON_EN_SETFOCUS(IDC_EDIT1, OnSetfocusEdit1)
END_MESSAGE_MAP

void CSampleDlgDlg::OnSetfocusEdit1() 
{
}

Are you asking how to show a tooltip? That's a new feature in XP, look up EM_SHOWBALLOONTIP

Strange error message

27-Jun-06 3:30

I all

I have the following scheme on two classes:

template <typename T> class MyClass {

 public:

   class MySubClass {

     public:

        ~MySubClass( void );
   };

};

And I tryed:

template <typename T> MyClass<T>::MySubClass::~MySubClass( void )
{
}

And also:

template <typename T> class MyClass {

   public:

     template <typename T> class MySubClass {

        public:

           ~MySubClass( void );
     };
};

With:

template <typename T> MyClass<T>::MySubClass<T>::~MySubClass( void )
{
}

But I get the message "error C2039: '__dtor' : is not a member of 'tBaseArray<T>'" for the 1st case and that same message plus "error C2935: '<Unknown>' : template-class-id redefined as a global function" for the 2nd case.

I tryed googling for __dtor, and it seems to be a function to enable using delete on a class, but I don't understand why I get this error neither how to bypass it.

Can anybody help?? =)

best regards

Its working fine with my VC++ 7 compiler

template <typename T> class MyClass {

public:

	class MySubClass {

	public:

		~MySubClass( void );
	};

};

template <typename T> MyClass<T>::MySubClass::~MySubClass( void )
{
}

i created the instance as follows

MyClass<int> t;

VC6's template support was not complete, especially when dealing with complex classes like your example. Sometimes, you just have to say it ain't gonna work in 6.

BTW, "dtor" is the abbreviation for "destructor" (along with "ctor" for "constructor")

How to get device context?

shivditya27-Jun-06 3:11

How to get device context from the runtime class used in multithreading application. For the application I am using single document interface.
Is there any easy way to get device context whenever and whereever you want?
The way of Creating device context with CreateDC seems to be worse than creating
another application. Where to get driver file name which drivers are installed by windows automatically.

A CDC* is passed to the view's OnDraw() method. The view's OnPaint() method creates a local CDC-derived object. Where else are you needing it?

In multithreading application we do pass RUNTIME CLASS.
In that runtime class we write the all the stuff which the thread is suppose to do.
Now my thread is going to draw something on document. My question is how to
achieve device context for the same purpose, and where to achieve
Moreover my application is crashing as I am not getting device context at the point
where I start using device context

How? The document is not something that can be drawn on. You can only draw on CWnd-derived objects (e.g., CView).

Friend sorry Its Single document interface application,CView is there.

David Crow27-Jun-06 3:59

27-Jun-06 3:59

Of course. It stands to reason that if you have a document, you will also have a view. What makes no sense is that you wanted to draw on the document.

Actually I dint get your question.

It is possible to get device context by passing Window handle to ::GetDC function.

I tried all the stuff but how to get handle of SDI window from the class instance which is used inside runtimeclass which is being called by SDI using
AfxBeginThread

void CMy5CYLINDERView::support()
{
for(int ii = 0;ii < 1;ii++)
{
x[ii] = AfxBeginThread(RUNTIME_CLASS(SHIV)); //SHIV is my RunTime class.

}
}

//FOllowing is constructor which is using another simulate class instance engine.
SHIV::SHIV()
{
engine.getdata(0);
engine.nextpos();
}
//And this nextpos method requires DC to draw

void simulate::nextpos()
{
CWnd* cc;
cc = (CWnd*)GetWindow(();
CDC* pDC = cc->GetDC();
CBrush bluebrush,old,white;
white.CreateSolidBrush(RGB(200,

which windows DC you want? MainFrame? Try AfxGetMainWnd() instead of GetWindow
