int nCount = strlen( source);
char *pRev = new char[ nCount + 1 ];
for( int nIdx = 0;nIdx < nCount + 1;nIdx++)
{
pRev[ nIdx ] = source[ nCount - 1 - nIdx ];
}
return pRev;

Assuming you're using the MS compiler, why not just view the CRT library source?
|
|
|
|
|
Or even better yet, why not do your homework yourself?

I would advise you to do that (your own homework yourself). You see, the code Naveen R provided contains some potentially hazardous "features", is highly sub-optimal, and will surely get you in big trouble when you try to explain it to your teacher.
Here is my contribution:
char* reverse_string(char* s) {
char* p=0;
while(s) *p=*s;
return p;
}
If you can't get this code to reverse the string this may mean you should study harder

Override WM_CONTEXTMENU..
CMenu menu;
menu.CreatePopupMenu();
menu.AppendMenu(MF_ENABLED | MF_STRING , ID_HELLO, _T("Hello"));
if(pWnd->m_hWnd == m_button.m_hWnd)
{
menu.TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON, point.x, point.y, this);
}
m_button is object of u r button...

menu.AppendMenu(MF_ENABLED | MF_STRING , ID_NEWITEM1, _T("NewItem1"));
menu.AppendMenu(MF_ENABLED | MF_STRING , ID_NEWITEM2, _T("NewItem2"));
just keep on adding as many items u want,..u can add separator,u can appened to existing menu also..
if(pWnd->m_hWnd == m_button.m_hWnd)..when u click on a button on dialog ,contextmenu appear,if u want it for whole just remove that line..that`s all...

Well using the below mentioned way u can move the progress ctrl:-
myCtrl.GetRange( nLower, nUpper );<br />
myCtrl.SetStep( (nUpper-nLower)/10 );<br />
myCtrl.SetPos( int nPos );
But according to your defn it feels that you want a busy control rather than a progress control .
