DOS Prompt

I've currently got a dialog based application which when the user clicks a certain button the program starts up a new thread. What I would now like to do is for this new thread to start (in) a DOS prompt window and then output various pieces of information to it.

Can anyone tell me if it is possible to do this and if so how I can do it.

cheers,
Andy

What is the purpose of outputting various pieces of information to a command prompt window? Are you instead wanting to run a program from a command prompt?

how to solution this error: class' type redefinition

wokankan9-Jun-05 22:09

am assuming that a 'struct' can be defined only once but not sure when / where it is defined.

Both 'IPHeader' and 'ICMPHeader' appear in 3 different files: rawping.cpp, rawping.h and rawping_driver.cpp .

My questions: assuming a 'struct' can be defined only once, when/where should it be defined?
(as the error appears in the header file, I'm guessing the compiler found the 'struct' in one of the .cpp files)

What other references to IPHeader and ICMPHeader need to be removed?

do you have a multiple-include guard on that header file?

#ifndef ICMPHEADER_INCLUDED
#define ICMPHEADER_INCLUDED

... definitions for those structs

#endif

?

I assume that you are learning C++.

Always in the header file! The rule of thumb is: Keep definition and implementation seperate. As you learn more about C++, you'll find exceptions to this rule.

flybest wrote:

I think that this is not the case. Your problem probably is that you implicitly included the headerfile with the definition multiple times. One solution are the include guards as Chris pointed out. An other solution is (if you are using MS Visual Studio) to add the following line to your header files:

#pragma once

Hope this helps

deflare it in only one header file, and include this header file from all cpp files that need to have the declaration!

Call GetDeviceCaps(hdc, LOGPIXELSX) on any device context that refers to the screen. You can use GetDC to get a device context for a given window.

No visible CListCtrl after Wnd restore

Member 9083819-Jun-05 22:03

9-Jun-05 22:03

Help me! Blimey!
When my CDialog, which contains 3 CListCtrls, is first minimized and later restored the lists are gone away in the case there was an update of the lists during the minimizing time. I have tried to manual invalidate,redraw (-items),update the lists and also the whole dialog by catching the restore event in OnSysCommand - but nothing works. I can reenable the lists in two ways: 1. automatic with the next update, 2. manual change the content of the lists with a button with some filter action in the background. As an ugly workaround i also tried to simulate this manual action by direct calling of the functions but that also doesn't work - i must do an mouseclick. Befor the next step is to simulate that mouseclick (i hope no one will ever see that), i hope somone can help me with right action for that case. !

Use the AllocConsole API function. Then, use the ReadConsole function to read from it, WriteConsole to write to it.

Dunno if that'd been answered before, but looks to me like it'd disable the keyboard. Do I get a prize?
