2)Add ::SetCursor(AfxGetApp()->LoadStandardCursor(IDC_WAIT));
3)Remove the base class call CView::OnSetCursor

vector math on different pc processors (amd, intel)

Hi,

I'm interested in porting some mac c++ code to PC. I use al lot of heavy vector math. There are, probably, libraries for this. But how do you use them all, so you don't have to create new applications or new code for every processor? (p3, p4, athlon, athlon xp, etc.)

Does anyone know if there are templates, macros or something for this?
I just looked at OptiVec (http://www.optivec.com/), does anyone have some experience with this?

Great to hear something, some pointers/url/etc,

Best Regards,

Aram

I can't understand how C++ vector math can be different under different processors.

The only difference could be when you use SIMD instructions.

OK, I'll put it like this.

I'm using SIMD instructions, are there some libaries which will convert my high-level code to the proper (processor dependent) low-level machine code, in order to get the fastest vector math possible on every PC processor?

Or do I need to build this in my self, checking which processor and then applying the right optimized vector code for that one?

what about www.optivec.com, could this be where I am looking for?

thanks!

I've not ever used the DOS subst command, but are you needing WNetAddConnection(), or maybe WNetUseConnection()?

I was talking about the subst.exe command.
I had a response : it's the DefineDosDevice(...) function.

go into the "Resource View" tab of your project and change both IDR_MAINFRAME icons to whatever icons you want Smile | :)

Did you change them both ?

BTW - there is an MSDN article on this subject also.

The easiest way is to replace the .ico file(s) in the Res folder.

hidding splitter windows

hi!

i have created three splitter windows like microsoft outlook in MFC SDI application. The splitter windows are created in OnCreateClient() function of main frame. Now i want to hide and show the left and bottom window on some events dynamically. I have tried to use deleterow() type of functions but it is giving exception. Unsure | :~

kindly tell me what to do? and how to resolve this issue? Confused | :confused:

The code for creating splitter windows is posted below for reference
// CODE

// create vertical splitter<br />
if (!m_wndSplitterV.CreateStatic(this,1,2))<br />
	return FALSE;<br />
if (!m_wndSplitterV.CreateView (0, 0, RUNTIME_CLASS(CLeftView), CSize(150,150), pContext))<br />
	{<br />
	m_wndSplitterV.DestroyWindow();<br />
	return FALSE;<br />
	}<br />
// create horizontal splitter<br />
if (!m_wndSplitterH.CreateStatic(& m_wndSplitterV,2,1,WS_CHILD|WS_VISIBLE|WS_BORDER,m_wndSplitterV.IdFromRowCol(0,1)))		<br />
	{<br />
	m_wndSplitterV.DestroyWindow();<br />
	return FALSE;<br />
	}<br />
<br />
if (!m_wndSplitterH.CreateView(0, 0, RUNTIME_CLASS(CSCR1View), CSize(500,500 ), pContext)|| <br />
		!m_wndSplitterH.CreateView(1, 0, RUNTIME_CLASS(CLowerView), CSize(0, 0), pContext))<br />
	{<br />
	m_wndSplitterV.DestroyWindow();<br />
	return FALSE;<br />
	}

There's at least one article here at CP that shows how to use CSplitterWnd with changeable views. Unlike other implementations that destroy and recreate the views as necessary, this one basically keeps them in a list of some sort.

Transparent Text to bitmap

The wording of you question needs work, but here is what you need.
SetBkMode(TRANSPARENT); (the text is drawn without drawing background).

If you need to be able to move the text around via draging then you will have to create a compatible bitmap of the appropriate size and draw the text on it then drag the bitmap around on top of whatever bitmap you are placing it on. In which case you will need to use the functions: GetTextExtent (to determine the size of the bitmap to create before drawing to it) and TransparentBlt (NT/Windows 2000) or some other method for drawing doing transparent blits. An example of one way to do transparent blits is in the code provided in CDibData and another in the MSDN library.

Good luck!
