It doesn't look like it.
Maybe you fooled the compiler by putting a break; after a return.
And why have a for() loop if it always exits the first iteration?

i want to know when a GetAt(i) is not letter (a-z A-Z) so it would be 1234567890!@$#^%^ etc
i want this so i can find how many words exist in a string

if (0 == _istalpha(str.GetAt(...)))
{
}
I don't know what the problem with isalpha/iswalpha was...
Regardless, look at your for loop - no matter what the condition, the function returns.
To the compiler there's no return after the for loop. If the for loop condition fails before the
first iteration, then no value is returned. We know the for loop will always execute (because
for (int i = 0 ; i <26 ...) but the compiler doesn't.

the _istalpha create me a problem and while it work fine for CStrings intiliaze and valued in code
it dont work for CString (buf) from File.txt
|
|

hmm well I never saw that code so I'm not sure why but it should work on any character you pass
to it.
There's nothing wrong with using your own function, but you probably want to fix it so
it works properly

you can see my code with alpha in below post
Different results when , compare 2 strings and 1 str with 1 str from file
|
|
|
|
|
can i ask something the isalpha how it works?
i mean i want only A-Z a-z i dont want numbers and !@#$~>time
isalpha work for that?
|

That's exactly what it does. It returns non-zero if the character is A-Z or a-z.
To find something NOT alphabetic then look for it to return 0.
From the posts below, it doesn't seem that this is the problem. It looks like you need to step
through your code and see exactly what's going on and in what order
If you are looking for matching words then why are you looking for non-alpha characters.
Don't you want to look for whitespace?

whitespaces = " " ?
That means this site (Codeproject) wouldn't reveal in my search because it is between ( ) ?
i thought an alorithm if the letter in i isn't character + letter in (i-1) is character then we got a word
"yes i think works correctly but not in my code 
so here with that algorith it would find 10 words
Well i will alt tab back to Visual studio and alchemy with isalpha
To find something NOT alphabetic then look for it to return 0. i think this helped me

By the way, you could replace the entire function with a call to _istalpha (isalpha/iswalpha).

it's so obvious that you forget to return after the loop.
You may think that it will definitely return inside the loop (it loops 26 times) but at compile time, the computer can't tell whether the loop will be perform or not. To the compiler, a for() loop is one kind of structure that can be ignored, that's why you have to put a return explicitly after the loop.

I have developed an application and I am wondering how I can prevent the main window from being displayed in the task bar even when it is visible; I am writing in plain C/C++ (no MFC)
Thanks for your help,

put this code in your OnInitDialog function
ModifyStyleEx( hWnd, WS_EX_APPWINDOW, WS_EX_TOOLWINDOW );

Thanks!
I used the foll: call to hide the taskbar:
ModifyStyleEx(0, WS_EX_TOOLWINDOW,0 );
Helped loads,thanks again.

Have a hidden parent for the window.

this is the best option ModifyStyleEx( hWnd, WS_EX_APPWINDOW, WS_EX_TOOLWINDOW );

Thank you for all of your replies

Have you looked into the IHTMLDocument interface?

Hi i have create a fuction to find how many words (str2) exist in line
int CInfoRecoverDlg::Compare( CString line , CString str2)
{
int nCount = 0;
int index=0;
for (int i = 0 ; i < line.GetLength() ; i++)
{
index=line.Find(str2,index);
if( index!= -1 )
{
if( !isalpha(line.GetAt(index-1)) && !isalpha(line.GetAt(index+ str2.GetLength())))
{
nCount++;
index++;
}
}
else
return nCount;
}
return nCount ;
}
When i compare 2 CString that i have initialize and give value throught my code everything work nice
like here
void CInfoRecoverDlg::OnButton1()
{
CString str1;
CString str = "yes";
CString line = "yes i said yes, yes yes ";
int nCount;
nCount = Compare( line , str);
str1.Format(_T("%d"), nCount);
AfxMessageBox(str1);
}
but when i compare 1 str (User give it throught application UI) with 1 line
(it get it from a file) things dont go well
<code> CArray<CString , CString> RArray;
CString FilePathName;
CString LineRead ;
CString str7;
int ntimes=0;
const int sz =100;
char buf[sz];
CString sl , slsl;
sl = "\\" ;
FilePathName = m_FolderName + FArray.GetAt(0);
m_List.AddString(FilePathName);
ifstream FileText(FilePathName);
while(FileText.get(buf,sz))
{
FileText.get();
LineRead = (LPCSTR) buf;
for ( int m = 0 ; m <WArray.GetSize() ; m++)
{
str7 = WArray.GetAt(m);
ntimes = ntimes + Compare(LineRead , str7);
}
}
FileText.close();
CString str13;
str13.Format(_T("%d"),ntimes);
AfxMessageBox(str13);</code>
