I appreciate the comment, but I have searched and looked around. I have found 2 articles which do the opposite of what I want (convert a number to a string like "1234" becomes "one thousand two hundred thirty four"), but none which do what I want which is to take "one thousand two hundred thirty four" and return 1234.

Here's a short and hopefully easy question...
One of our designers would like me to display some items in a list view right-justified, but have the title in the column header left justified. Does anyone know how to do this?
Any help would be greatly apprecaited...

Take alook at the list control section here and micheal dunns custom draw section. You could probbaly make use of that to right justify the required text.
I even think there may be an example in his article to do it.

How ca i do it if my control will be have lenght like 2-3 or more standart SystemTrayIcons ?
How can i replace standart tray tools - like clocks digits with my own controls ?
Thank you !
Live samples will be great !

My submenus are dynamic.
I think I understand the concept of setting up an WM_MENUCOMMAND handler for the submenu of a toplevel menu which I will make suitable with SetMenuInfo (NOTIFYBYPOS). I want to notify by the index of the submenu item pressed. Fine. Now if I press on item 1 " SubMenu 1" , index 0, a flyout I'd created at the same time (CreatePopup)as I was creating "SUbMenu 1" dynamically , pops out . This has its own list of items.
I want stuff to happen when I press t hese flyout items. Now the toplevel submenu handle needed for SetMenuInfo I can get by GetSUbMenu(). Can I use my same trick for the flyout:
CMenu* submenu = mmenu->GetSubMenu(pos);
except now it will be
subsubmenu = submenu->GetSubMenu(pos) (after I get the right pos in the submenu?
I cant test it out because I'm beseiged with a zillion problems before I can get to this stage, and dont want to go through the effort if my supposition wont work....
Thanks,
Appreciate your help,

MSDN says:
BOOL SetMenuInfo(
HMENU hmenu,
LPCMENUINFO lpcmi
);
Heres what I have done, and have #include winuser.h: My aim here is to press any one of the dynamic menu items that get created under the top level "mapdyn" and have it trigger the OnMenuCommand handler which sends in the index. I hope I have the correct menu handle etc (???), and am having trouble compiling:
CMenu* mmenu = ((CMainFrame*)AfxGetMainWnd())->GetMenu();
int pos = ((CMainFrame*)AfxGetMainWnd())->FindMenuItem(mmenu, "mapdyn");
if (pos == -1)
return;
CMenu* submenu = mmenu->GetSubMenu(pos);
HMENU m_hMenu = submenu->GetSafeHmenu();
LPCMENUINFO lpcmi;
lpcmi.dwStyle = MNS_NOTIFYBYPOS;
::SetMenuInfo(m_hMenu, lpcmi);
Compile error :
C:\BKView.cpp(176) : error C2065: 'LPCMENUINFO' : undeclared identifier
and the rest that follow....

When you set the MNS_NOTIFYBYPOS, can it be done for a submenu only, or only a subsubmenu? Or is it that the whole menu has to be that way?

As you can see in the documentation for MENUINFO and related stuff, this is only available in Windows 98 and later and Windows 2000 and later. VC++ 6.0 helps you avoid inadvertent use of APIs not present in baseline Windows 95 and NT 4.0 by not including anything incompatible with these. So, if you really want to use MENUINFO, inform the compiler about the target platform by inserting
#define WINVER 0x0500 before #includeing winuser.h. Please note that your program won't run in 95 or NT systems!
PS: if this doesn't work try inserting the #define in stdafx.h, right at the beginning.

I put it in stdafx.h:
But I do get:
NOTE: WINVER has been defined as 0x0500 or greater which enables
Windows NT 5.0 and Windows 98 features. When these headers were released,
Windows NT 5.0 beta 1 and Windows 98 beta 2.1 were the current versions.
For this release when WINVER is defined as 0x0500 or greater, you can only
build beta or test applications. To build a retail application,
set WINVER to 0x0400 or visit http:
to see if retail Windows NT 5.0 or Windows 98 headers are available.
See the SDK release notes for more information
=========================================================
And got rid of the #include for winuser.h
According to http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnw98bk/html/thewindowshheaderfile.asp I dont need to explicitly include it...
Now I'm getting:
HMENU m_hMenu = submenu->GetSafeHmenu();
LPCMENUINFO lpcmi;
<code>lpcmi->dwStyle = MNS_NOTIFYBYPOS;</code> line 195
SetMenuInfo(m_hMenu, lpcmi);
C:\BKView.cpp(195) : error C2166: l-value specifies const object
I must be doing something really dumb!!!
Actually, for some reason my machine MSDN doesnt have CMenu as h aving a SetMEnuINfo member, but the web mSDN does!!!!!!
SO I think I might just do
submenu->SetMenuInfo( lpcmi);</
and skip the HMENU stuff.
My local MSDN isnt that old!!!!

C:\BKView.cpp(195) : error C2166: l-value specifies const object The error says it all! You're defining a pointer to a const MENUINFO and trying to fill it: two errors here, the const-ness thing prevents you from changing the contents and you haven't allocated any space for lpcmi. What you surely will want to do is the following:
HMENU m_hMenu = submenu->GetSafeHmenu();
MENUINFO mi;
mi.cbSize=sizeof(MENUINFO);
mi.dwStyle = MNS_NOTIFYBYPOS;
SetMenuInfo(m_hMenu, &mi);

Yikes! I am sooooo blind! Thanks!
I modified my post above to include the caution I got about WInver....do I need to worry about that? You said it wont work on NT4. Is that right? I need it to work on NT4, but not worried about win95...
Appreciate your help,
ns

Well, as for the warning it is sweet from Microsoft that they inform you about the convenience of downloading the latest SDK. If you have time I'd recommend you to do it, altough in this particular simple case you won't probably need it.
The NT4 problem seems unsovable: docs are very precise in stating that MENUINFO functionality is not available in NT 4.0.

From the MSDN I found the requirements too...so I wonder how people handled getting the index of the menu item and running an index specific handler (not ID specific) on NT.
Requirements
Windows NT/2000/XP: Included in Windows 2000 and later.
Windows 95/98/Me: Included in Windows 98 and later.
Header: Declared in Winuser.h; include Windows.h.
BTW, its happy now since the constantness issue is resolved (and I still think they shouldnt have said LPCMENUINFO in the argument for SetMenuInfo..I guess they mean they will treat it as constant after it goes in....do you agree? . So before we pass it in , we have to do it like you showed me, and pass the address...

This idiom may be difficult to understand at first, but it is most usual: Win32 (and almost any other library you can think of) is crowded with examples similar to this with regard to the const pointer issue. After all, the idiom seems more natural if you consider that the function invoked can do little with a const pointer except reading its contents, so it makes sense that the caller be responsible of filling them.

My next effort is putting in the message map entries for my submenu handler for WM_MENUCOMMAND...I'll be back with more questions I am sure.
Do you think I am correct in understanding that if I give SetMenuInfo a partiicular handle, only that menu will be NOTIFYBYPOS, and my other menu items will be running the usual COMMAND handlers? I havent tested that yet either....so stuff I added under File, View etc retains its normal behavior...
Appreciate your help,

Okay. My other menu stuff seems to be normal, and I havent yet messgagemapped the one I setMenuInfo for.

What SDK do I want? Do I want the SDK for Microsoft Platform SDK in the download section? Or do I need a Visual Studio 6 SDK (is there even such a thing? ) I didnt see a VS SDK link, but theres stuff for .NET SDK. But I'm using VS6, and Win2K.
I looked up SDK in MSDN but I couldnt decide whose SDK I need.

I'm working on an MDI project and I want it to be possible to open more than one instance of a given document. How do I force OpenDocumentFile() to create a new doc/view even if a document has already been opened from the given file?
|
|
|
|
|
Take a look at the CMultiDocTemplate class. When a document file is opened it checks in this calss to see whether the file is already open. You will need to modify/override this behaviour.

Please help.
I created a dialog app that contains a picture control which acts like a button.
The picture control (IDC_MODEL_COLOR) will bring up the common dialog CColorDialog and allows the user to select an RGB color. This color will then repaint the picture control to show the user the color that was selected.
My problem is in initialization and the odd case of toggling focus between my app and another window on the desktop.
Initialization Problem:
The correct color of IDC_MODEL_COLOR is not displayed when my dialog appears.
(See code for constructor and OnInitDialog() below and the visual at
http://www.dlowracing.org/mmedia/Dialog_Black.gif 3kb
http://www.dlowracing.org/mmedia/Dialog_Red.gif 3kb -- what should be)
Toggle Problem:
When I change focus between my dialog app and another window on the screen, without moving either window, the picture control is not repainted. For example, if part of
IDC_MODEL_COLOR is covered by another window and I toggle focus between the two (Without moving either window), the part that was covered is not repainted.
(See http://www.dlowracing.org/mmedia/CColorDialog_.gif 9kb)
Below is the code that supports my dialog based app.
Thank you for your help.

sorry for the long post.
The references are to visuals that would help explain my situation - CColorDialog_.gif (or CColorDialog.gif same thing) is an animated gif
that shows effects of the Toggle Problem i'm experiencing.)
Thanks again for any help.

Hello everbody:
I was wondering if it is possible to have more than one line in the string that is going to be displayed in a tool tip? I gave it a try with the following code, but is displayed all in one line and there is a small square in between the two strings that I want to display:
<br />
CString displayLine;<br />
CString idString;<br />
idString.LoadString(IDS_TT_DCSRAW);<br />
displayLine.Format("%s\nHi Res", idString);<br />
.<br />
.<br />
.<br />
m_ToolTip->AddTool(this, (LPCTSTR)displayLine,rFileTypeCoord, 1);
Is this a Tool Tip attribute that I have to set? Is there another way to put the new line character? Any answer is more than welcome.
Best regards,
Luis E. Cuadrado
