Can VC++ launch MS Dos window then issues Dos commands? [modified]

Sam Hobbs

You can execute the command prompt using CreateProcess or ShellExecute and use the "/K" option in the command prompt's arguments.

It is the same, I did try system("pause"); It is pause but the previous MS DOS Window still disappear! So it shows an empty MS DOS Window ... but it stay there until I press a key!

ATC

I try ShellExecute(this->m_hWnd,"dir/k", "","","", SW_SHOW ); it does not work! Can you give a typical DOS command? Thanks

Stephen Hewitt

Can you describe your application a little. For example, is it a console application or a Win32 application?

It is a WIN32 MFC application

Stephen Hewitt

Try this: // DOSCommands.cpp : Defines the entry point for the application. // #include "stdafx.h" #include <process.h> #include <conio.h> int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) { AllocConsole(); system("dir"); system("tree"); getch(); FreeConsole(); return 0; }

Glad I could help.

Please stop saying DOS! First, did you search for previous answers? It is nearly certain that this question has been asked and answered many times before. When I said command shell, I meant command-interpreter. Look at the documentation of the system function. It is useful because it describes how the filename of the "command-interpreter file" is determined. For NT type versions of Windows, the command-interpreter file is Cmd.exe. For 95 versions of Windows, the command-interpreter file is Command.com. Those names might change for future version so it is better to get the filename from the environment. You need to execute the command-interpreter and pass the options and command on the command line. Note that this will create a new window for the command; if that is not what you need, then I am sorry for misleading you.

Stephen Hewitt

While you're correct you seem to be being a little pedantic; I think we both know what he meant by the question.

I did not know what was meant by the initial question and the answer could have depended on the difference. People trying to help often waste their time answering a misunderstood question. People asking questions should try to be clear. In this situation, this person is not trying. It is now not important for this question, but this person will likely waste people's time in the future. My guess is that this person is not using the best solution for their fundamental problem. They probably think that this solution is the easiest, but then they will need to enhance it some more and the final solution is likely to be more work than if they considered all their requirements initially and asked for solutions for all the requirements.

Stephen Hewitt

I understood what he meant. Sometimes people do be vague and it annoyes me, but in this instance I didn't have any problems.

I have not been very active in CodeProject, but in the CodeGuru forums I was the first to hit 10,000 posts and about 99% of them were efforts to help others. So I have seen quite a few vague questions and such. People often spend less time asking a question than we spend answering them. In this situation, my guess is that there are better answers if the person were to take the time to be clear about requirements.

Stephen Hewitt

I can't argue with you there.
