Hello World,
I have a simple class
class CData
{
public:
CData () {}
CData (CObj obj, unsigned short a) {m_obj = obj ; m_a = a ; }
private:
unsigned short m_a ;
CObj m_obj ;
};
and a list of this type of object
typedef CList < CData, CData& > CDataList ;
Something odd happens when
CObj Obj ;
unsigned short a = 10 ;
CDataList TheList ;
TheList.AddTail(CData(Obj, a)) ;
TheList has one more element, and the data in m_obj is perfect. However, the value in m_a is not correct! It gets a random value.
If I change the default constructor to
CData(unsigned short a = 5) { m_a = a ; }
and do the same thing TheList.AddTail(CData(Obj, a)) ; m_a equals 5 (that is, the default value in the default constructor) and not the value passed when constructing the object...
I've tried to reproduce this problem in a different project and I can't. I guess there is something wrong with one of the classes I've defined. Any idea??

Do you have a copy constructor and are you copying all the members inside of it as well?

Where/how are you verifying this?
I tried your code, and the CData object in the list did indeed contain the value 10 for the m_a member variable.

I am able to display a bitmap using bltblit() function.
Now i have a raw image buffer. I want to display this data to my window using the device context.
I have the current HDC.
should i have to create a bitmap from this raw buffer.
Please help me.

I guess it depends on the raw image buffer format.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

What is the solution for this problem?

As I've already pointed out, knowledge of the raw image data format maybe a good start.

I am not getting your point.I have a 800 x 600 x 4 RGBA raw image buffer.
I want to display this on current HDC.
My question is should i have to create a bitmap for this buffer and then should i use bltblit () function.
Curently i am able to display a bitmap on current HDC.
Please elaborate your idea in little details.
Thanks,

Is there is any other alternative other than creating a bitmap?
Thanks,

IMHO nope. But there are a lot of tutorials about.
Have a look at GDI articles here at CP.

Thanks for you help.But i am not understanding one thing that, if it's not possible to do this in any other way then what you are suggesting to find me in the GDI tutorials?
Thanks,

Is there any freeware tool to find out only GDI leaks in a project.
Can anyone tell me the occurances of GDI leaks.

Well you can use of Task Manager it displays GDI resources for each process.

Using Visual C++ 6.0 MFC in SDI application
I'm relatively new to C++ (from C). In an application using Visual C++ MFC, I setup a menu item. When that menu item is selected, my code calls the following routine that was setup by Visual C++
CMainFrame::ShowTheCircle()
{
// has my code here...
}
I want to perform this identical operation from another place in my code, which is in a separate .cpp file. I don't understand how to call the ShowTheCircle function from this other place.
void MyCode(void)
{
// call the ShowTheCircle function just as if the menu item was
// selected
// thanks for your help!
}
|
|
|
|
|
One way would be to make ShowTheCircle() a static method. Another would be to make it not part of the CMainFrame class.

void MyCode(void)
{
CMainFrame *pWndMainFrame = dynamic_cast<CMainFrame *>(AfxGetMainWnd());
pWndMainFrame->ShowTheCircle();
}
provided CMainFrame is the class for the main frame window of the application.
|
|
|
|
|
ShowTheCircle is a method of CMainFrame class, therefore to call it you must have a reference (or a pointer) to a CMainFrame object, for instance
CMainFrame * pMainFrame = (CMainFrame *) AfxGetMainWindow();
CMainFrame * pMainFrame = (CMainFrame *) AfxGetMainWnd();
pMainFrame->ShowTheCircle();
Note that ShowTheCircle must also be declared public.
BTW what about a good C++ tutorial?

Thanks to all for the help. The function in your reply should have been AfxGetMainWnd() and not AfxGetMainWindow() but I found things. Everything worked great!

Of course. Fixed: thank you for pointing out.
