Did you read the forum guidelines [^]?
You should be specific, for instance what kind of rotation do you need (arbitrary angle, simply 90 degrees steps,...)? What's your bitmap format? What code did you make?

hi i am just doing processing on image like just reading image by imread() and after that rotating a image by imrotate() may be an angle thita in matlab so i need this c code of this matlab function which i can burn on micro controller

Is your CPMRU working well? Mine seems broken. Moreover I cannot get a piece of useful info from his posts.

BTW: After 'data mining' we should introduce a new discipline: 'data guessing' (and I suppose we need more 'intelligence' for this 'business').

Hence you need to a function to rotate an image by an arbitrary angle. This is the maximum info you provided so far. I can just give you this link [^]. Good luck.

PRINT PREVIEW ZOOM COMBOBOX

Hi Friends,

I need to show zoom combo box in print preview window like Microsoft power point print preview.

I removed zoom in and zoom out buttons.

I dervied my class i.e.

class CPrintPreviewView : public CPreviewView
{
  void SetScaledSize(UINT nPage);
}

void CPrintPreviewView ::SetScaledSize(UINT nPage)
{
switch(m_nZoomState)
{
case ZOOM_25:
     pRatio->cx = 25
     pRatio->cy  = 100;
break;

case ZOOM_400:
   pRatio->cx = 400
   pRatio>cy  = 100;
break;
}
}

I inserted the zoom combobox and added zoom levels from

25% to 400%, as user selects value in cobmobox, I update zoom ratio and call DoZoom function.

But there is some calculation problem.... ??? I dont know what ??

But if i keep zoom in & zoom out buttons and click zoom out button once
and then use combo , there is no problem.

Everthing is fine.

Can you please provide me some code snippet.

Thanks,
Subhash Madhukar

There is a bit of guessing going on here, but I would think that the OnSelChange for the combo box would need to call:

SetZoomState(requiredZoomLevel, 0, CPoint(0, 0));

where requiredZoomLevel maps to the the correct zoom level of:

0 for totally zoomed out
1 for next zoom level etc...

If you vote me down, my score will only get lower

Hi,
i have a Slider ctrl and im calling SetRange(1,3,TRUE) and when im trying to drag the slider from one position to the other ..ie OnHScroll(UINT nSBCode,UINT nPos,CScrollBar *pScrollBar) is called...

and in this if the nsBCode is SB_PAGEDOWN im always getting the nPos value is 0 eventhough the position of the slider is changed...and when the nsBCode is SB_THUMBPOSITION evrything works fine...

Please help me regarding the same...

MSDN says

For the TB_THUMBPOSITION and TB_THUMBTRACK notifications, the high-order word of the wParam parameter specifies the position of the slider. For all other notifications, the high-order word is zero; send the TBM_GETPOS ( GetPos ) message to determine the slider position. The lParam parameter is the handle to the trackbar.

MD5 using openssl

Looking at the documentation for MD5 in openssl[^], it looks like it's as simple as calling the MD5 function:

const char* msg = "This is my message";
unsigned char digest[MD5_DIGEST_LENGTH];

MD5(msg, strlen(msg) * sizeof(char), digest);

Problem Compiling in VS 2005 after installing microsoft platform SDK for Windows Server 2003 SP1

As the title suggests I'm having a problem compiling MFC based applications, this problem started immediately after installing the windows server 2003 platform SDK and now even when I try to compile a new MFC project I get the following errors:

in some cases I solved the problem by including/moving windows.h and defining WIN32_LEAN_AND_MEAN at the top of stdafx.h. However for large projects that uses static and dynamic linking to other libraries the proposed solution did not work. I'm not really sure why this is happening as I've also tried to reinstall the platform SDK to no avail.

Any help is appreciated.

Thanx Smile | :)
