I want to know how exactly to add the button at the top of the search to note as the search criteria is for example asc to desc or vise versa
your attachment is unreadable. what compiler, operating system, and gui library are you using? But it should be a simple thing to place a button wherever you want it and add the text "up" or "down", but maybe a checkbox would be better suited for that.
this might help?
operating system is xp
visual studio
the work of this button should be like if i click on it then based on the asc or desc it has to place the arrow up or down
what arrow? I guess you want to add another button with an arrow, like a toggle between up and down.
Is that an MFC program?
yes that is what i meant can you help me with that
Just add a button, set it's property to hold a picture, then add the picture of the arrows. In the OnClick event handler change the picture from up to down, or vice versa and set a BOOL flag accordingly. The hardest part is finding the two pictures you want to use, or use the icon editor to create your own.
how to Add arrow to indicate column sorted on by and order asc/desc in c++ was my question
how to incorporate the arrow button in exisitng application as shown in the above attachment :(
you want the arrow to appear on a button, right? Study the links I gave you and they will tell you how to do it.

// Base the size of the triangle on the smaller of the column
// height or text height with a slight offset top and bottom.
// Otherwise, it can get drawn outside the bounds of the cell.
size.cy -= (nOffset * 2);
if (size.cy >= rect.Height())
size.cy = rect.Height() - (nOffset * 2);
size.cx = size.cy; // Make the dimensions square
// Kludge for vertical text
BOOL bVertical = (GetFont()->lfEscapement == 900);
// Only draw if it'll fit!

}
}
if (HasButtonsInCell ())
rect.DeflateRect (3, 0, 0, 0);
// We want to see _T('&') characters so use DT_NOPREFIX
DrawText(pDC->m_hDC, GetText(), -1, rect, GetFormat() | DT_NOPREFIX);
pDC->RestoreDC(nSavedDC);
return TRUE;
}
this is the code written is it fine ?
how should i call the function in button :(
I assume that code is drawing an arrow on a button. If that's true then put the code in the button's OnClick event handler.
can you explain or provide links for the same :(
Don't you have the slightest idea how to write MFC program? Or use VC++? If not, then google for tutorials. I already gave you lots of links, its up to you to study and learn.
any type of help is really appreciated :(
Thank you all for your help
