Try to put a breakpoint at switch, or use MessageBox, in order to see which value contains row[0]. If it contains an unexpected NULL or a non-numeric string, then atoi returns 0.

Please read this article[^] on why you do not want to use GetDlgItem and how you can avoid it while makeing your code mor readble.

The author Joseph M. Newcomer is a old regular here on codeproject. His Page is full of great tips.

"We trained hard, but it seemed that every time we were beginning to form up into teams we would be reorganised. I was to learn later in life that we tend to meet any new situation by reorganising: and a wonderful method it can be for creating the illusion of progress, while producing confusion, inefficiency and demoralisation."

if CMainDialog is main dialog and CLocalDialog is another dialog use this code in another dialog

<br />
CMainDialog* m_Main = (CMainDialog* )GetParent();<br />
m_Main->m_Youredit.EnableWindow(0);//disable or 1 enable<br />

string::const_iterator in VC8

The problem with the compiler VC8 is as follows:

<br />
char sz[]="Hello";<br />
std::string s=sz;<br />
std::string::const_iterator iBegin,iEnd,iPos;<br />
<br />
//string<br />
iBegin=s.begin();<br />
iEnd=iBegin+3;<br />
iPos=std::find(iBegin,iEnd,'e');<br />
<br />
//char<br />
iBegin=std::string::const_iterator(sz,NULL);<br />
iEnd  =iBegin+3;<br />
iPos  =std::find(iBegin,iEnd,'e');<br />

Is it possible to avoid const_iterator(sz,NULL) without using the defines

<br />
#define _HAS_ITERATOR_DEBUGGING 0<br />
#define _SECURE_SCL 0<br />

Or must I copy the char array into stl:string? Is it really standard const_iterator(ptr, this)?

Re: string::const_iterator in VC8

If is acceptable, for searching in sz string you can use std::find function in this manner:

char * p = std::find(sz, sz + 3, 'e');

In this case you do not need iterator. I don't think the const_iterator can be constructed in your code. It is supplied for you by STL.

Yes, I know this. My problem is const_iterator and iterator. I have installed the new Visual Studio 2005 and after that I run into this problem.

When I use the standard

<br />
std::string::const_iterator iBegin;<br />
<br />
iBegin=std::string::const_iterator(sz);<br />

I get the compiler error

<br />
error C2440: '<function-style-cast>' : cannot convert from 'char [6]' to 'std::_String_const_iterator<_Elem,_Traits,_Alloc>'<br />

STL iterators only make sense when used on a matching STL collection. Iterators are not pointers. Using iterators on a C array is iffy at best.

Masked input (standard c++)

Peter Charlesworth12-Jun-06 0:13

12-Jun-06 0:13

Hi guys

I have a question: is it possible to mask the user input by using a pre-determined symbol?

Like when a password is being inputted, instead of the actual password, '*'s will appear to mask it. Is this possible in std c++ and if it is, how do I do it?

Thanks in advance!

Regards,

Peter

the output is UI/platform dependant, not standard C++.,

What exacly are you trying to acheive ? you want to do the same in a console application ?

Yes, I wanted to achieve that in a console app.
I was afraid it wouldn't be possible, but I had to know for sure.
Thanks for confirming my hunch!

I am not sure there is such a feature in STL or C++ libraries.

Using Windows API, you can try at least to hide the input while the user enters the password. Investigate the SetConsoleMode function with ENABLE_ECHO_INPUT flag. Also you can try to read each character separately in a loop and print '*'s yourself.

It required little logic to reach there, Call GetParent() to reterive Pointer to Parent Property sheet, then by calling CPropertySheet::GetPage to reterive the Pointer of Specfic Page whoes variable you want to access...

Yet the subject says "use the variable of another property sheet."

If you are simply wanting one page to communicate with another, create a class/structure that is owned by the sheet. Load/store data in that.

There's no need for one page to communicate directly with another.

You can investigate how SetSilent member of the CHtmlView class affects the functionality.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
