How do i open a file in C++ (Windows Form Application)

[LAfSLyTq]

i have used microsofts own code and all they did was confuse me and cause errors, have to restart now... can somone tell me how to open a file without a dialog box by clicking a button?

Within your button click handler you can use the standard ifstream or if you want the .NET equivalent. The dialog box is only for getting the file name.

thanks for your help, but that makes a text reader, im trying to open a file as in run the file...

There's only two parts to this, opening a file and handling a callback. You've been given code for both. If you still have problems, maybe you're not asking the right question.

That's new, no wonder you weren't getting a relevant answer.

Specify the full path+file name when you open the file.

If you don't specify the path, the file is opened in the current directory, and that isn't always what you think it is. To see the current directory, see GetCurrentDirectory.

Check yourself before you start pointing the finger at others.

You asked how to open a file. If you want to execute an external binary try

using namespace System::Diagnostics;
...
Process::Start("notepad.exe");

If not, try being a little more descriptive with what you are looking for.
