It is also redundant since the first test catches that condition also.

And catches any file or directory whose name starts with '.'.

What you have so far looks good enough.

There is an API called SHFileOperation that can take multiple wild cards.
But you cannot use this to find files.
You have to either copy or move or rename or delete the files.

I'm not sure what exactly your application does but if you can copy the files to a another folder or temp folder, this API may be helpful.

How to move buttons to the left side？

How to move windows titlebar (included buttons: Close & Minimize & Hide) to the left side ?

What I want to do is to move buttons to the DockablePane left side. I've created a derived class of CDockablePane.

Thanks,

One way could be to handle WM_NCPAINT[^] and WM_NCHITTEST[^] and draw and handle hit testing yourself (possibly using the themed drawing methods like DrawThemeEdge[^] and such for the drawing).

How to tile multiple windows in a single view

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.

Reference to a pointer question

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 ??

Re: Reference to a pointer question

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.

C++

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.

Window IME language

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:

//-----------------------------------------------------------------------------
// IME_MessageProcessor
//
// 
//-----------------------------------------------------------------------------
void CI_CHINESE::IME_MessageProcessor(UINT message, WPARAM wParam, LPARAM lParam)
{
	int len;
	if(wParam == 0xe5) return;
	
	//이건 웈기 식으로 end안거칠때의 처리
	if(message == WM_CHAR && ImeRunning())
		return;
	
	HIMC m_hIMC=NULL;
	HWND ImehWnd=ImmGetDefaultIMEWnd(g_hWnd);
				
	switch (message)
	{
	case WM_IME_STARTCOMPOSITION:
		// When focus change, enter garbage value in input buffer.
		gbl_skip_escape = true;
		g_pDXInput->SetAcquire(false);
		ShowWindow( ImehWnd , SW_HIDE );
		ShowWindow( ImehWnd , SW_SHOWNORMAL );
		SetFocus(g_hWnd);
		g_pDXInput->SetAcquire(true);
		
		//			SetStartComposition();
		//			IME_StartComposition();
		//			SetGapEscape();
		break;
	case WM_IME_ENDCOMPOSITION:
		//			if(ImeRunning() || !m_bl_end_of_ime)
		//				SetGapEscape();
		//			SetEndComposition();
		IME_EndComposition();
		break;
	case WM_IME_COMPOSITION:			
		//			SetGapEscape();
		gbl_skip_escape = true;
		m_hIMC = ImmGetContext(g_hWnd);
		if(lParam & GCS_RESULTSTR)
		{
			if ((len = ImmGetCompositionString(m_hIMC, GCS_RESULTSTR, NULL, 0)) > 0)
			{
				//					SetStartComposition();
				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;

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.

CList with Pointers

VentsyV10-Sep-10 7:05

VentsyV

10-Sep-10 7:05

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?
