I'm assuming you're asking how CTestDoc is referenced in the CTestView class in the TestView.h file.
If you look in the TestView.cpp file you will see the following 2 lines -
#include "TestDoc.h"
#include "TestView.h"
Here you will notice that TestDoc.h is included before TestView.h.
This way the CTestView class already knows about the CTestDoc class.
Change this to the following and you can expect errors at exactly the place where you're talking about -
#include "TestView.h"
#include "TestDoc.h"

Probably the include is done by one of the standard MFC include (afx.h or something similar)
In general, the document does not know the view(s); the view know about the document (GetDocument)
When the document (CDocument derived class that contains the data(*)) is modified then there should be a message is sent to update the views or in the case of the CDocument a method is called (CDocument::UpdateAllViews) that will eventually call (by message?, don't recall the exact mechanism) CView::OnDraw which should be overriden in your CView derived class so that the view is refresh after a change in the CDocument..
Watched code never compiles.

You could probably give it a quick test by referring to this page[^].

thanx alot....I had just done it but using CFile class and could not find the exact way.

You're welcome. Don't forget when using managed code (VC++.Net) that you cannot also use MFC classes. However there are also many useful file handlers in the System.IO namespace[^].

Hi!
When I run my application, it crashes at this line curTab->getElementFromId(i)->remove();and displays:
Unhandled exception at 0x00632175 in SlogOut3D.exe: 0xC0000005: Access violation reading location 0x00000000. When I view the Memory contents at this location 0x00632175, it has:
8b 11 8b f4 8b 8d 18 ff ff ff 8b 42 18 ff d0 3b f4 e8 3e 64 ee ff eb b1 5f 5e 5b 81 c4 e8 00 00 00 3b ec e8 2c 64 ee ff 8b ...ô...ÿÿÿ.B.ÿÐ;ôè>dîÿë±_^[.Äè...;ìè,dîÿ.
curTab is a pointer.
What is wrong with this program? How to run with out crash?
|
|
|
|
|
"0xC0000005: Access violation reading location 0x00000000" means you are using a NULL pointer.
So either curTab is NULL or getElementFromId(i) returns NULL. You can fix the crash by checking the curTab-pointer and the pointer returned by getElementFromId(i) before using it.

Hi all,
i draw a rectangle by CDC::Rectangle function,
CDC* pDC;
CRect rect(10,10,50,50);
pDC->Rectangle(rect);
CBrush brush;
brush.CreateSolidBrush(RGB(210,210,210));
pDC->FillRect(&rect,&brush);
before using FillRect function Rectangle boundries are visible properly but when i user FillRect to Fill color in rectangle the rectangle boundaries are not visible.
and i am insert text in this rectangle,with TextOut function i also want to set the background color of the text as same as rectangle color.
please help me for this.
thanks in advance.

You probably need to use InflateRect()[^] or similar to change the limits of your rectangle before you do the fill, in order not to overwrite the borders. As to the text I think SetBkColor()[^] will probably do it.

alternatively you could first fill the rectangle, then draw the rectangle's outline.

That is illogical Captain.

depends on how your rectangle is defined and what tools are available for filling.
In .NET you could easily do
Graphics.FillRectangle(...);
Graphics.DrawRectangle(...);
using the same rectangle for both, not having to insect by an amount that depends on the pen characteristics.
BTW: if it works well, it doesn't have to be logical all the time!
|
|
|
|
|
Yes, it always depends ...
I know there are some rules in Win32 about where the rectangle actually ends relative to its start point and width or height, so one has to take that into account when rendering this sort of picture. I may run some tests later to remind myself how to do it.

Hello folks!
I am using this[^] method to control the initialization order of some global objects. I have (plans for) a class that will be instantiated all around the code, all instances will be globals, i was wondering, is there maybe a way to specify that i want all instances of this class instantiated in a given segment so i don't have to use
#pragma init_seg("aseg$x", some_method);
CIWantThisInSegX whatevera;
CIWantThisInSegX whateverb;everywhere and instead i can just create the instances and they will be placed in the correct segment "automatically"? Maybe by specifying a new operator for it? If it was possible it would help a lot because it is enough to forget the init_seg part only once and havoc might get loose.
Thanks in advance for any ideas.
