I need better control of multiple windows opened in one MFC document / view.
Ideally I would like to be able to tile / cascade / select these windows in similar fashion as MFC main frame does. Anybody can point me to article / source code for such task?
I am not looking for multiple views connected to same document.
Any constructive help is as always appreciated.
Thank you for reading.

Are the views in the same frame window? If so, then you can use the MDICascade( ) method like standard MFC.
|
|
|
|
|
As ShanghaiDan said there are methods like CMDIFrameWnd::MDICascade and CMDIFrameWnd::MDITile that can do this for you.
There are also APIs called CascadeWindows and TileWindows that can do the same thing.

Thank you.
Both anwers are correct, however, I was looking for cascading windows and not views.
I need to use the API to do that.
Works as advertized in MSDN.

I have the following:
class Object
{
string data();
}myObj, *myObjPtr;
myObjPtr& GetObjPtr();
I would like to do the following:
myObjPtr& pTest = GetObjPtr();
string data1 = pTest->data();
That results in memory access violation. Is there a way to cast the myObjTtr& to myObjPtr ??

You're referencing a pointer, which is only confusing. Either reference the object, myObj&, or use pointers.
class Object
{
string data();
}myObj, *myObjPtr;
myObjPtr GetObjPtr();
I would like to do the following:
myObjPtr pTest = GetObjPtr();
string data1 = pTest->data();
This would work. With a reference, you need to ensure the object that is orignally referenced (in this case this is a pointer variable) is still in scope; in this case this is done inside your GetObjPtr() function so I can't see what is going wrong.
For your code, you should probably stick to pointers and forget references. Or, depending on the rest of your code, perhaps you could stick to references and forget about pointers.

You mixed up your identifiers a bit.
class Object
{
public:
string data();
}myObj, *myObjPtr;
Object& GetObjPtr()
{
static Object o;
return o;
}
Object *myObjPtr1 = &GetObjPtr();
string data1 = myObjPtr1->data();
Are you writing a template class and depend on this to work? There might be other solutions if you give more input.

It is completely unclear what your intentions are. The statement
myObjPtr& pTest = GetObjPtr();
only makes sense if myObjPtr is a type, but in your example it is an object. Also myObjTtr does not appear at all, so I don't know what it should represent. Last but not least, 'a reference to a pointer' is a separate type in the weird c++ world, for example
Object *& tReferenceToPointer
reads from right to left as tReferenceToPointer is a reference to a pointer to Object.
So please clarify what you mean. The 'memory access violation' comes from an attempt to access something via unitialized pointer to it.

Whevever someone says "How do I cast..." and "access violation" in the same sentence you know that something's going horribly wrong with their understanding of C++. In your case you aren't telling us the whole story as most of the code you presented wouldn't compile.
When you wrote:
myObjPtr & GetObjPtr();
You weren't writing a function prototype, you were bitwise anding the variable myObjPtr with the result of the function GetObjPtr and discarding the result. If you declared this in a function it would have compiled to nothing, outside of a function it wouldn't compile.
The same sort of thing's happening when you write:
myObjPtr& pTest = GetObjPtr();
You're not writing a declaration but you're trying to assign the result of a function called GetObjPtr (which you didn't declare, see earlier) to the result of bitwise anding myObjPtr with another variable you haven't declared (which is an rvalue) which won't compile.
Just out of interest:
class Object
{
}
myObj, *myObjPtr;
is generally a bit daft as of you stick this in an include file and then include the file in multiple Cpp/Cxx files you'll get loads of multiple copies of myObj and myObjPtr which is probably not what you want - it won't link for a start.
So if I were you I'd scrap this lot, work out what you want to say and then try again saying it in the language.
Cheers,

HI,all
I iave some problem for IME, I have some game source and input language is chinese but i want to change input language to thai, How can i do it. I know this game is use IME for input language and i don't understand IME, Please help me.
This some function for chinese language:
void CI_CHINESE::IME_MessageProcessor(UINT message, WPARAM wParam, LPARAM lParam)
{
int len;
if(wParam == 0xe5) return;
if(message == WM_CHAR && ImeRunning())
return;
HIMC m_hIMC=NULL;
HWND ImehWnd=ImmGetDefaultIMEWnd(g_hWnd);
switch (message)
{
case WM_IME_STARTCOMPOSITION:
gbl_skip_escape = true;
g_pDXInput->SetAcquire(false);
ShowWindow( ImehWnd , SW_HIDE );
ShowWindow( ImehWnd , SW_SHOWNORMAL );
SetFocus(g_hWnd);
g_pDXInput->SetAcquire(true);
break;
case WM_IME_ENDCOMPOSITION:
IME_EndComposition();
break;
case WM_IME_COMPOSITION:
gbl_skip_escape = true;
m_hIMC = ImmGetContext(g_hWnd);
if(lParam & GCS_RESULTSTR)
{
if ((len = ImmGetCompositionString(m_hIMC, GCS_RESULTSTR, NULL, 0)) > 0)
{
ImmGetCompositionString(m_hIMC, GCS_RESULTSTR,m_composing_string, len);
m_composing_string[len] = NULL;
IME_NextComposition();
memset(m_composing_string,0,128);
gbl_skip_escape = false;
}
}
ImmReleaseContext(g_hWnd,m_hIMC);
break;
default:
IME_Normal(message, wParam, lParam);
break;
}
}

Unless you are using a very common acronym, it would help to explain what IME is?

yes it's Input Method Editor

You can't change the language of an IME editor. Each IME editor is built to support just one language. Windows provides IMEs for Chinese, Japanese and Korean, but no Thai, AFAIK.

I have something along the lines of:
typedef CList<MyObjPtr, MyObjPtr> PTRLIST;
MyObjPtr pMyObj1 = CreateObject();
PTRLIST* myList = new PTRLIST;
if(pMyObj1 && pMyObj1->isValid())
myList->AddTail(pMyObj1);
I know the pointer is valid and the list is empty, but when I try to add to the tail I get an exception. I traced it to where it's trying to new a new node.
Any ideas?

What kind of exception did you get?
Could you post the erro message?

Memory access violation 0x000...5

Have you tried narrowing the problem down to just the code you've shown? I tried the following (with a few syntactical changes) and it worked:
typedef struct _MyObjPtr
{
public:
BOOL isValid( void ) { return 1; }
} *MyObjPtr;
typedef CList<MyObjPtr, MyObjPtr> PTRLIST;
MyObjPtr pMyObj1 = new _MyObjPtr;
if (pMyObj1 && pMyObj1->isValid())
{
PTRLIST* myList = new PTRLIST;
myList->AddTail(pMyObj1);
}

I stepped through the code and it's narrowed to pretty much that. The AddTail is calling NewNode which it appears is trying to deference the pointer.
In afxtempl.h NewNode function (Line 931)
::new( (void*)( &pNode->data ) ) TYPE;
And it fails there.

I used CTypedPtrList<cptrlist, myobjptr=""> PTRLIST; and that seems to be working.

Hi
my program print a form-view correctly if it does not have scroll bar.
if scroll bar is present then we can print only visible area of scroll bar.
But i need to print full form-view with all control .
i.e. scroll bar should not be effect on print procedure.
many sample available but no one fulfill above requirement.
|

The view that you see on the screen is merely one 'page' which you can scroll up, down, left and right. After each scroll operation the view is repainted to show just the data within the current view. In order to print all pages you need to add some similar print logic to your program which will iterate through all your data formatting it correctly to the printer device of your choice.
It's time for a new signature.

Here is an old post of mine that describes printing in MFC in a generic way. It was written for CScrollView but I'm hoping it'll help regardless...Printing Sample[^]

Thanks for response
it work good but, my requirement is still open.
my form view have many control and scroll bar hide some control so
how can print full image of form view.
