Answer 1

MessageBox(0, "And text here", "MessageBox caption", MB_OK);

The example I gave is plain Win32 API. See here:

In C++/CLI (including WinForms) you can do this:

MessageBox::Show("Any text here");

or this:

MessageBox::Show("CLR MessageBox", "MessageBox Test",
  MessageBoxButtons::OK, MessageBoxIcon::Exclamation);

Hi Tanruberdi,

Welcome to the MSDN Forum.

Here are some samples in C++ applications of MessageBox for you, please refer to them for help:
1->In win32 Windows Application:

MessageBox(NULL, _T("Open the message box "),_T("message"),MB_OK|MB_SYSTEMMODAL);

2->In C++/CLI windows application:

MessageBox::Show("The operation has been completed ","Notification", MessageBoxButtons::OKCancel,MessageBoxIcon::Asterisk);
if (MessageBox::Show("Do you want to exit?","My Application", MessageBoxButtons::YesNo,MessageBoxIcon::Question)==::DialogResult::Yes)
{
Application::Exit();
}

3->In MFC application:

AfxMessageBox(_T("first message box"));
AfxMessageBox(_T("do you want to leave?", MB_YESNO|MB_ICONSTOP);

Best regards,
Helen

If you still have problems it's because within the form and button you have to completely call the full path for the result. 

->>  System::Windows::Forms::DialogResult::Yes

EXAMPLE:

if (MessageBox::Show("Do you want to exit?","My Application", MessageBoxButtons::YesNo,MessageBoxIcon::Question)==System::Windows::Forms::DialogResult::Yes)
         {
MessageBox::Show("You pressed YES!", "STATUS INDICATION");
         }
else
{
 MessageBox::Show("You pressed NO!", "STATUS INDICATION");
}

I'm sure there is a way to convert the full path in another way and use it. But at least it's working and solving your initial problems.

Any hints or way's for converting are welcome ;)

If you still have problems

After two and a half years? I hope not. ;-)

Just adding the statement by itself doesn't compile anymore.

MessageBox::Show("Any text here");

In Visual Studio 2017 gives a slew of errors, starting with Name followed by :: must be a class or namespace name, must be a class or union, and "Show" identifier not found. So things have apparently changed since this question was answered.

Whats the new quick & dirty way to throw up an alert box if you're working with the dialog box system given to you in the "Build a windows ap in 5 minutes!" starter kit? The alerts and such that are pre-build with the toolbox are working fine, but that's not so useful for displaying dynamically generated text on the fly...

Nothing changed : it is C++/CLR

You should start your own thread instead of tacking on your problems to
a thread that is almost seven years old and long since answered.

If you start a new thread on this, provide more specifics. Don't assume 
that we all know what kind of project you're building, what your code
looks like *exactly*, etc.

If you are building a program using the Win32 API, then the posts in this 
thread also show how to get a MessageBox that way. Note that they assume
that the program has:

#include <windows.h>

Note that it isn't a "new" way. It is the original way to do it in a 
Windows program.
