You could use one of those several options out there:

LZMA SDK[^]

Zip and Unzip in the MFC way[^] (If you're using MFC)

ZLib[^]

You could search Google and find many more.

Hi hraman,

Remove the 'sort' style of your list box and everything will be alright.

Best Regards,
Jijo.

By default, Visual Studio sets the LBS_SORT style (forcing alphabetic sort) when adds a Listbox control to your window. To remove it, in the Resource View pane, select the Listbox and then set the Sort property to False.

You are welcome.

Another approach would be to left-pad the numbers with a 0. That may go against your design, however.

Hi. Well... I'am trying to make my own transparent button, but i need to rotate it to. I tryed to use SetWorldTransform function to make a rotation, but it results in clean dialog. Pls tell me what do i do wrong?

	void MPictureBox::DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct)
	{
	
		CDC* pDC;
		pDC = CDC::FromHandle(lpDrawItemStruct->hDC);
		m_rtfmdc = new CDC;  
		m_rtfmdc->CreateCompatibleDC(pDC);
		m_rtfmdc->SelectObject(m_bmp);

/*	  XFORM xf = {cos(angle),   sin(angle),
                  -sin(angle), cos(angle),
                  0, 0};*/   
	  
		int Rotate=1;
		XFORM xf = {0,1,-1,0,0,0}; //angle = 90
	int OldMode = SetGraphicsMode(*pDC,GM_ADVANCED); 	
	  SetWorldTransform(*pDC,&xf);
		
	  switch (MBStyle)
	  {
	  case MBUT_TRANSPARENT:
			 pDC->TransparentBlt(0,0,ButSize,ButSize,m_rtfmdc,ButSize*ImageNumb,0,ButSize,ButSize,RGB(0,0,0));
			break;
	  case MBUT_SOLID:
			pDC->BitBlt(0,0,ButSize,ButSize,m_rtfmdc,ButSize*ImageNumb,0,SRCCOPY);
			break;

		default: 
			MessageBoxA("Nepravilnie parametri prozrachnosti");

What kind of reason will cause CWnd derived class failed to be created?

transoft8-Oct-09 11:31

Hi

I designed (using VS class wizard) a class which was derived from CWnd. I did following in my View.

The Create function will return "0". According to MSDN, it failed.

pRulerX = new CRuler();

int ret = pRulerX->Create(_T(""), _T("rulerx"), WS_CHILD | WS_VISIBLE, CRect(0, 0, pRulerX->RulerHeight, pRulerX->RulerHeight), this, 55355);

From debug:
ret = 0;
pRulerX's m_hWnd is "NULL"

Thanks,

_T("") is different from NULL or 0.
The first parameter of Create can be NULL or 0, but not _T("").

Just to add, hope you have valid values for pRulerX->RulerHeight and pRulerX->RulerHeight.

I changed as following:

int ret = pRulerX->Create("CRuler", "rulerx", WS_CHILD | WS_VISIBLE, CRect(0, 0, 0, 0), this, 55355);

the "ret" is still "0".

If you look at the documentation of CWnd::Create[^] you will see that the first parameter of Create must be either NULL or a name that is registered using the AfxRegisterWndClass function or one of the predetermined class names.

Try this -

int ret = pRulerX->Create(0, "rulerx", WS_CHILD | WS_VISIBLE, CRect(0, 0, 0, 0), this, 55355);

MFC application using different Windows theme

Myzrael8-Oct-09 8:50

Hello everybody,

My question is if it is possible for a MFC application to use a theme, different from the theme of the Windows itself e.g the application to use "Windows XP" theme (or some modified theme) and the Windows to use "Windows Classic" theme. If there is some way of doing that I would appreciate a clue or two =].

Greetings, Peter

There are a lot of samples in codeproject talking about this topic. Just search for it using key word "theme".

VS 2008 can generate this type of application.

Is there any way ,that i could access to special icons like "My Document" Folder icon or "Contacts" Folder Icon or even "My Computer" Icon of the operating system.

I know how to access system Image list using this function

HIMAGELIST GetSystemImageListOfSmallIcons()const {
	HIMAGELIST himl;
	SHFILEINFO sfi;
	himl = (HIMAGELIST) (::SHGetFileInfo( _T(""), 0, &sfi, sizeof(sfi), SHGFI_SYSICONINDEX | SHGFI_SMALLICON));
	return himl;
}

but is there any way ,that i could access to special icons like "My Document" Folder icon or "Contacts" Folder Icon or even "My Computer" Icon of the operating system.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
