Hello all,
I am trying to take the contents of a textbox, and display it as part of a custom message on a message box. I can display either my message, or the contents, but I'm having trouble getting both. I searched the help, but couldn't find an example. Thanks for any help. Here is my code (with explanatory comments):
{
// This code is from the button1_Click event. Clicking the button should take the
// text from a textbox and display "You entered <insert textbox text here>"
// Create a sting, assign contents of textBox1
String^ msgboxInput = textBox1->Text;
// I need equiv. of printf("You entered %s", msgboxInput) to display in message
// box, but I can't figure out how to combine "You entered " and msgboxInput.
// I can display either, but not both.
MessageBox::Show( "You entered ", "Thanks for testing this box!",
MessageBoxButtons::OK, MessageBoxIcon::Exclamation );< xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
}

But I tried it dynamically, and it works:
String^ msgboxInput = "You entered " + textBox1->Text;
Messagebox::Show( msgboxInput );
Also:
String^ msgboxInput = textBox1->Text;
String^ msgboxOutput = You entered " + msgboxInput;
Messagebox::Show( msgboxOutput );
Thanks.

System::String::Format< XML:NAMESPACE PREFIX = MSHelp NS = "http://msdn.microsoft.com/mshelp" />
Then I was hoping you would click on the link to find information on that function. You would click on the first overload, and discover the ins and outs of String::Format(String^, Object^), and learnt that .Net carried slightly different syntax to sprintf. Then after having read the documentation, you would have realized you could have done:
String ^msgBoxInput = String::Format("You entered {0}", textBox1->Text);
And then you would have realised how useful Online Help could be. I'm a little disappointed that didn't happen.
At least you know about String::Format now, so when the time comes when you need to build something complex like:
("Are you sure you want to {0} the {1} named, {2} to the {3} \"{4}\"", EnumMoveOrCopy.ToString(), "system file", fileName, "folder", "C:\Recycled");
You'll know how to do it.
ps. don't forget to mark a post as answered.

If you are looking for the .Net equivalents of C functions, you should consult the Visual Studio help for them. At the bottom of the printf help page, you can clearly see the .Net Framework Equivalents to printf
isare:< XML:NAMESPACE PREFIX = MSHelp NS = "http://msdn.microsoft.com/mshelp" />System::Console::Write
What's that System::Console::WriteLine isn't what you want Could it be that you didn't actually want the equivalent of printf, you really wanted the equivalent of sprintf
By the way, you could have also built your string dynamically like
"You entered " + msgBoxInput;
