well my suggestion would be as follows.
int someFuntion(){
for(;;)// causes to loop infinite times, its 2 semicolons.
{
if(gets(c)=='x'){
return 0; //or break; /*breaks out of loop.*/
}
else{
keep going;
}
return 0;
}
i think the above is not a good model and is only necessary when nothing else would work. It is said that a clean program should have 1 entry point and 1 exit point. This does not follow that guideline.
the thing is there are so many things you can do with this.
such as
while(done!=1){
cin>>command;
if(command!='x')
{
done=0;
}
else
do more;
}
Also here is your problem. When you cin you recieve a string once you press the enter button. When you use the function toLower() in the ctype library you are comparing 1 char value. i think this would cause a segmentation fault(exception) if the user types XX by mistake. if you wish for 1 char then i think it would be appropriate to use something like getchar() or getch() not sure what the proper name is but use that instead. When you use C++ don't forget that C is a big part of the C++ language. It was necessary for C++ to be a superset of C simply because of simplification.

disregard the cin string part, late night cuz early blindness. sorry if i got you worried, but i got myself worried.

cin>>command;
while(done!=1)
{
if(command=='x')
done =1;
else
do more;
}
or
for(;;)//infinite loop
{
if(command=='x')
break;//break out of loop
else
get more info;
}

It would be nice if you could write something like,
<br />
bool GetInput ()<br />
{<br />
...<br />
}<br />
<br />
while ( GetInput ())<br />
{<br />
ComputePrice () ;<br />
PrintTicket () ;<br />
}
So 'GetInput' becomes a function returning a bool, and returns true for good input which you should continue to process and false for exit. I'll leave all the details out.
Hope that makes some sense.

I suggested int GetInput() only because I can't find any bool type in core C++.;)

Hi Roger.
'bool', 'true' and 'false' are all C++ keywords. By definition 'true' has the value '1' when converted to an integer and 'false' becomes 0 so most things work as expected.
I once worked on some old style C code where hidden in a header file was,
#define TRUE 0
#define FALSE 1
which explained a lot once I'd found it...

I knew it had to be there somewhere; I can't imagine a language that doesn't have a logical data type. But in the references I have, bool (or an equivalent) isn't listed. Oh well, my int suggestion at least conforms to the concept (though logically, from a hardware guy's POV, true=1).

Possibly, assuming I understood your question better. What you have presented thus far (i.e., save one application from another application) does not make much sense.

if i have CString a="a;b;c;d;f" and i want to split it to CString array.
how can i do it on VC++ NET ?
|

If you're using MFC7, have a look at CString::Tokenize() function. Otherwise look at the api function strtok()
Or have a look at

MFC4 has AfxExtractSubString, which should do a lot of what you want.

1. How is this a question ?
2. So now Java has templates, they have an STL - what does that prove, except that the STL was a good idea ?
3. What is there to prove ? Any language that takes nothing from any prior languages will either be a disaster, or a revolution. Java is neither....

JSTL really has nothing to do with C++ STL. It is a tag library for JSP (Java Server Pages).
BTW Java is getting generics (just like C#), not templates in version 1.5.

Yes, I think people saw the title and neglected to even skim over the article. Even a cursory glance would have made it quite obvious that JSTL is completely different from the C++ STL.

hi guys sorry for bothering u all again... I noticed that OnSize was called before OnCreate? In my OnCreate,
<br />
OnCreate function<br />
<br />
mSomething.Create(...);<br />
mSomething.ShowWindow(...);<br />
<br />
OnSize function<br />
<br />
mSomething.MoveWindow(...);<br />
and when it runs, an assertion is thrown BUT...
if i do it this way:
<br />
OnSize function<br />
<br />
if(mSomething.m_pHwnd)<br />
mSomething.MoveWindow(...);<br />
it works well... perfectly. So does this means that OnSize is fired before OnCreate? Freaky...

How do you work that out ? Between OnCreate and OnSize, the window is created, hence in OnSize you don't get an ASSERT because the window you're trying to move exists.

Onsize event is for the frame/view window that has been already created.
Its ur own created window is failing.

Has anyone seen anything like this before?
http://www.sagara.org/menu.gif[^]
Notice the File menu (left-most). Those garbled characters are supposed to be Japanese characters. Everything in the File menu is garbled, just like that. However, everything else on the rest of the menu renders just fine. In fact, throughout the whole rest of the UI, Japanese text renders perfectly. It's just in the File menu that it doesn't work correctly. The really annoying thing is that the Japanese characters show up correctly in the resource editor.
I had the translator re-type in the text and re-saved the file, but that didn't work.
I tried pasting in the text from the Edit menu, but that didn't work, either.
I'm stumped. Any help would be appreciated.
Thanks!
(BTW, the program is written with VC6, using MFC. It runs on Windows 2000+.)
[edit]
This seems to be a positional thing. I edited the resource file so that the Edit menu came before the File menu and then recompiled. This caused the Edit menu (now the left-most menu) to be garbled, while the File menu rendered correctly.
Does this ring any bells?

I have a static text label in a straight-Win32 app I'm working on, and I'm wanting the cursor to change to a hand icon when the mouse moves over it (and back to normal when the mouse moves away). What's the best way to do that? It appears that it's possible using RegisterWndEx, but then I have to code a text control myself; there has to be a simpler way.
|

I don't know if this would be simple enough for you, but the standard way of creating 'hyperlinking' controls is :
define your own CMyStatic : public CStatic.
Now override OnNcHitTest and return HTCLIENT, this will cause windows to ask you for a cursor, otherwise it won't, e.g.:
<br />
UINT CMyStatic::OnNcHitTest(CPoint point)<br />
{<br />
return HTCLIENT;<br />
}<br />
Now override OnSetCursor and set your hand icon within it, e.g.:
<br />
BOOL CMyStatic::OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message)<br />
{<br />
::SetCursor(LoadCursor(NULL, IDC_HAND));<br />
return TRUE;<br />
}<br />
That's it.

Thanks, that worked; I didn't even need to implement the NCHITTEST message in my WndMainProc  .
