I want my dialog to sometimes show a ToolTip when it opens up (when the dialog opens up).
I want to do thsi regardless of wether the user is hovering over a specific control or anything of that kind.
I've been looking for something like CToolTipCtrl::ShowMeNow(...) but alas I couldn't find one.
I found that TTM_POPUP should do the deal, but it's defined for XP and above only :
#if (_WIN32_WINNT >= 0x0501)
#define TTM_POPUP (WM_USER + 34)
can someone please help ?
thanks

So write one!
void MyApp::DisplayToolTip(CPoint& pt,CString* m_pMyToolTip)
{
CString str = m_pMyToolTip);
if (str.IsEmpty())
return;
SetWindowPos(NULL,il, it,iw, ih, SWP_SHOWWINDOW|SWP_NOCOPYBITS|SWP_NOACTIVATE|SWP_NOZORDER);
}
Now you finish it!
Good luck and best wishes,
Marty

I have done a keyboard hook and in my callback function i have to check for
each character
if (wParam >= VK_NUMPAD0 && wParam <= VK_NUMPAD9)
then it is checking correctly for numeric keypad nos
but if i want to check for
if (wParam =VK_A)
then it is giving an error
undeclared indentifier vk_A
but i havent declared for vk_numpad0
Are there anybody to help me

If you look in the header file where VK_NUMPAD0..9 etc are declared you will see that VK_A..VK_Z do not exist, but map directly onto the charaters 'A'..'Z' which can be used in their place.
if (wParam == 'A')

HICON LoadIcon(
HINSTANCE hInstance, // handle to application instance
LPCTSTR lpIconName // icon-name string or icon resource
// identifier
);
Hi, I want to use LoadIcon function to get the icon from other application, I can provide the hInstance, but how can I know the icon's name?
Thank you!
How can taskmgr.exe retrieve those running application's icon?

OK
Let me restate the question and see if I have it right.
You want grab an ICON on the fly from another application and display it right?
Well first you need to create a function to enumerate all the open windows, this requires a call back function. Many articles on this site for that.
?? When you get a parent window handle from the callback do you want to grab the icon for All or Some?
Icon 0 is alway the IDR_MAINFRAME ICON
I have not done this in several years but here is what I remember, at least a good start!
Pass cshandle from the callback
hwndyourapp = is your app.
CWnd* pWnd = cwhandle;
if (pWnd)
{
HWND hwndyourapp = pWnd->GetSafeHwnd();
// Make sure that the window doesn't 'belong' to you if ((::GetWindowThreadProcessId (GetSafeHwnd(), NULL))
!= (::GetWindowThreadProcessId (hwndyourapp, NULL)))
{
m_strHwnd.Format("%ld", hwndyourapp);
// Get the class name
char lpClassName[255];
if (::GetClassName(hwndyourapp, lpClassName, 255))
{
m_strWndClass = lpClassName;
m_strWndClass.MakeUpper();
// Is this an ICON
if (m_strWndClass.CompareNoCase(/*svb "ICON"*/strSel) /*svb!= -1*/== 0)
{
// Get the window's style
LONG lStyle = ::GetWindowLong(hwndyourapp, GWL_STYLE);
char szText[255];
::SendMessage(hwndyourapp, WM_GETTEXT, 255, (LPARAM)szText);
// Just in case is this an ICON
if (m_strWndClass.CompareNoCase(_T("ICON")) != 0)
{
char szText[255];
::SendMessage(hwndyourapp, WM_GETTEXT, 255, (LPARAM)szText);
}
}
}
// go get the next parent win from callback }
}

Look up EnumResNameProc / EnumResourceNames to work out how to get the names of icons
in a specific loaded module.
Task manager will just take the first icon, as does explorer unless told otherwise.
SHGetFileInfo may also help, if you don't have a HMODULE / HINSTANCE.

What about gwb?
What part of it?
gwb is white house, Yes?
well what part of whitehouse?
WhiteHouse gwb;
gwb.p(2000);
or
gwb.~WhiteHouse;
but not gwb(2000);

in f() you are assigning ww to fdr.
Now when the function returns fdr goes out of scope so the destructor gets called. so the variable p of fdr (which is the same as that for ww) is deleted (becomes free for reuse) and subsequently the variable p in ww becomes an invalid pointer.
in main when you declare gwb, the constructor calls new to assign a memory location to p. since the memory location held by the old p is free it (can be) is allocated to gwb->p and assigned value 2000. But ww->p still points to this location and so it's value is 2000 too.
hope this helps more than it misleads

i tested each os that below code in Win98,Win2000.
but different value this variable "procFunc".
i guess wrong value in Win98.
what is wrong? i just get address BitBlt in gdi32.dll.
how can i get right value. gave me your advise.
///////////////////////////////////////
// code start
HMODULE hMod;
FARPROC procFunc;
// Right get value.
hMod=GetModuleHandle("GDI32.DLL");
//or
hMod=LoadLibrary("GDI32.DLL");
// wrong get value.
procFunc = GetProcAddress(hMod,"BitBlt");
////////////////////////////////////////

Are you getting a value other than NULL?
If so, what makes think it is wrong on win98? There is no one value for this function. Depending on the OS or even the Service Pack, it might be different.

it not value is NULL.
so i find same result in WinME.
|

As long as the value isn't NULL, you shouldn't care at all what the value is. Expect it to be different on every different computer you run the program on. Your software should never care what the value actually is.

I can't seem to figure out how one layers bitmaps. And, can one layer things that aren't bitmaps, like CStatics? Also, what's the best REDO/UNDO method for a publisher-like program?

Manually, by keeping several bitmaps with transparency keys.

No, they don't have a transparent background, unless you're using W2000 or higher ( maybe )

Read 'Design Patterns' for some good ideas. It's on Addison Wesley ( I forget the authors name ).

So, is there a way to do something like save the visual aspects of a CStatic as a bitmap, and then layer it for display? Or would that cause weird laggy stuff for the user, or other lame problems?

If you're not supporting Windows95 you can use TransparentBlt, otherwise search the Windows Developers Journal article backlog at www.wdj.com, I have an article there that shows you how.

Statics are just text, so store the text, and draw it onto a bitmap and show that. Other controls, you have to worry about them getting click messages and so on as well, you should develop a control to hold other controls, display them and get them their messages properly. Sounds like hell to me.

I am having some problems figuring out how to programmitcally group buttons with a toolbar control.
If you want the following:
+-----------------------------------------------+
| btn1 | btn2 | btn3 | | btn4 | btn5 | | btn6 |
+-----------------------------------------------+
\______ _______/ \___ ____/ \_ _/
\/ \/ \/
group 1 group 2 group 3
How do you indicate which group a button is in?
What breaks the group? The separator (ie using the TBSTYLE_SEP) ?
