Re: Using Microsoft C++ 6.0 instead of using old C Compiler...

depends how old they are, some dos staff might not be supported anymore. What is wrong with the old compiler? If all you want to do is to use VC, in VC 7 you can specify custom compiler (non MS), in VC 6 you can check "Always use custom build step"

Hiya using the old C Compiler is ok but abit crap because I would like to use 6.0 to be able to compile the old dos programs and my new stuff, instead of continually changing between the two ...

I know Visual 6.0 is a Windows based compiler, but surely it can do this.

Were is the "Always use custom build step" and what exactly I am checking it for??

thanks,
grahamoj.

1. The steps I mentioned are to use 3rd party compiler from VS 6 and 7. Project settings is the place to configure it.
2. If talking about 16-bit dos, it most probably would not compile with 32-bit MS compiler. If your code is 32-bits - just create a project and add your files there. There could be some dependencies missing (include directories, libraries etc.) but it is easy to configure in project settings.

I guess I do not understand what exactly is the problem with converting(adapting) the code.

Get point size from font?

Hi, can I get the height in point size (not logical size) from a font ?

LOGFONT lf;
GetFont()->GetObject(sizeof(lf),&lf);
return lf.lfHeight;

From MSDN:
lfHeight - Specifies the height, in logical units

Thx for help, Moak

PointSize = lfHeight * 72 / GetDeviceCaps(hDC, LOGPIXELSYS);

Here is the source on MSDN.

lfHeight = -MulDiv(PointSize, GetDeviceCaps(hDC, LOGPIXELSY), 72);

Solution:
PointSize = lfHeight * 72 / GetDeviceCaps(hDC, LOGPIXELSY);

Cut off your thumbnail and hold it under a light. Look underneath the thumbnail, and you'll see a shadow...

XML Document

Jamie Hale28-Jan-03 8:06

I'm building an application that will use a XML file as a document. The application will simply load the document and allow the user to edit it - adding nodes here and there. The editing will be done in custom controls, so I'm not looking for a generic XML editor...

My question is this: would it be wise to use the DOM as my document? That is, would my CDocument-derived class simply maintain and update an IXMLDOCDocument? Or would it be better to load the XML then convert to an internal format (converting on save as well)?

Use the DOM, much less work. Its generaly wise to only have a single model of your data, and the DOM is about the best way to represent an XML document. It would probably be good to have your controls directly editing nodes too.

This is what I figured. Thanks for the input!

Extracting a number from text...

I need to take an input string of something like "one thousand, 2 hundred and 54" and turn that into 1254 as an integer. I know how to write an algorithm to do this, but I am hoping someone can point me to one that already exists.

Ideally, it would be C++ and non-MFC.

Thanks,

If you know a solution, then implement it. Originality has its advantages including experience.

Knowing how and having time are conflicting right now. Besides, I am not one for reinventing the wheel everytime a problem arises. I agree that originality has advantages, but when I have a low priority need I always look for existing code/tools/libraries before I invest my time into coding a solution. I would much rather use someone elses code (IF: it works, is clean, looks well written, has been used by others, works, is not someting that is critial to my system, works, etc).

I am afraid, that my question may have come off as a "school problem" type question, but I assure you, that is not the case. I just have a request for a feature which is low on the priority list and was interested in a "quick" solution.

There is an article on here that tackles the exact problem you need solving. I can't remember where it is, but if you dig deep enough you should find it

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.

subsubmenu flyouts....

ns28-Jan-03 6:56

28-Jan-03 6:56

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,

Using SetMenuInfo

ns28-Jan-03 6:24

28-Jan-03 6:24

MSDN says:

BOOL SetMenuInfo(
  HMENU hmenu,       // handle to menu
  LPCMENUINFO lpcmi  // menu information
);

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....
