I have a CWnd Derived window. I have added several Child windows.
[main window]
[title_win]<-child window
[main_view_win]<-child window
I create the child window [main_view_win] using WS_CHILD|WS_VISIBLE|WS_HSCROLL|WS_VSCROLL the scroll bar exists and works however there are two problems.
problem one.
the scroll bar buttons initially are not drawn. ( thumb and middle part are drawn ) Once they are clicked on they are drawn properly.
when the child window [main_view_win] is covered by another window ( for example notepad ) the scrollbar's do not redraw until they are physically clicked on.
I have tried the following with no luck.
Made sure no other child window was overlapping.
Tried with clipchildren clip siblings turned on
turn off all painting functions to make sure i was not doing something stupid.
turned on and off erase background.
I did a quick test adding a scrollbar as a seperate child window and it worked just fine.
I was about to change my code ,illiminating the WS_VSCROLL and WS_HSCROLL, then I thought the smart people of codeproject might know what is happening.

I want to add 2 matrices (2 dimensional), using 2 methods.
1. Pointer To Array Method
2. Base Address of Array Using Int Pointer
Anyone please help me.

What is your trouble about?
It's basic pointer handling...You know, proper pointer handling is required to access the real programmer initiation.

Does this get you started:
void main( void )
{
int A[2][3] =
{
{0,1,2},
{9,8,7}
};
int B[2][3] =
{
{6,5,4},
{3,4,5}
};
int C[2][3];
for (int x = 0; x < 2; x++)
{
for (int y = 0; y < 3; y++)
C[x][y] = A[x][y] + B[x][y];
}
}

Newmat10 is a very powerful and neat library for matrix manipulation containing many useful functions. It might be helpful to you. Go to internet download it and try it!

From documentation [^]:
The display area of a tab control is the area in which an application displays the current page. Typically, an application creates a child window or dialog box, setting the window size and position to fit the display area. Given the window rectangle for a tab control, you can calculate the bounding rectangle of the display area by using the TCM_ADJUSTRECT message.

See here[^]
The article is about Outlook 2007.
And here[^] is an article (includes adding contacts) for automating Microsoft Outlook 2000, 2002, 2003 and older versions.
I hope this helps.

while rotating rectangle in c by draging mouse how can i calculate the angle ......
actually I want to rotate rectangle dynamically on mouse event like open office.

Your question is short, but the answer heavily depends on how much math knowledge you have.
Possibly the biggest tip I can give anyone who ever wants to deal with graphics is to go back you your end-of-school (ie A-level) math books, and learn about matrices (matrix-es) and vectors. It's fine if you don't know it now. If you are unwilling or unable to do this, quit now and start learning how to say "would you like fries with that?".
That said, the following will help, I think:
Angle between vectors[^]
For a more complex dragging about of shapes, have a look at the following, superbly written and illustrated, article:
Warping Coordinates with Matrices[^] by me!
If you don't already know about it, I'd advise you learn about SetROP2(R2_NOT) for your mouse handling code, to draw / undraw tracking lines.
I hope that helps steer you in the right direction. A more exact answer would depend on the details of your application and skill level.
Good luck,
Iain.

to add to warrior panda's reply :p, you can try [this] to understand vectors. Once you know that, you should not have any problem calculating angles or rotating a rectangle. you just need to specify the rotate center and angle of rotation and then rotate each of the 4 vectors obtained by joining rotate center and 4 corners. easy, huh?

1. get the coordinates of the two points on the 'top' edge. (this assumes one of them is the anchor point of the rotation)
2. find the change in x and change in y (dx and dy)
3. use atan(dy/dx) (or atan2(dy/dx)) to find the angle in radians of the line that connects them
watch out for div by 0

Try putting this line at top of file.
#pragma comment(lib, "Oleacc.lib")

|

Did you link your project with Oleacc library, because AccessibleObjectFromWindow()[^] needs this library.

Also this line contains syntactic errors.

In the above code, I'm getting HRESULT hr ="E_FAIL".
main objective is to get value in pWindow. I might have missed some link.
Any suggestions? Thanks in advance.
