[john113]

Can someone please tell me why this code does not give a output of text box?

Hi

Thanks for the help.

But it still does not print a window, it just prints out Press any key to exit!

any idea why?

A bit confusing... Did you build the project as console application? Also, you need to add a function to your code to receive keyboard input.

the program is working correctly, it's a console application so the text appears in the console box.

add the "inkey" command as last command, then when u start the exe directly from explorer u will see that the console title is also changing as desired ...

I was trying to create a Macro using it, then call the macro ---> print "message",13,10

I was able to get it to work and it prints the message on console window. How can I use the macro to print few lines?

if I try
print "message",13,10
print "message",13,10

It only prints one line..

For the MASM32 print macro, something like this will work:
print "this",13,10,"is",13,10,"a",13,10,"5-line",13,10,"message",13,10

hm,

now i'm a bit confused too,
u have created a new macro with that code and named the macro "print" ?
i would change the macro name to something different so it can't be confused with the original masm macro.

in ur code u have  cursor positioning, so if u execute it twice there appears only 1 line on the console... maybe thats the explanation...
