I´m writing a windows form application.
Consider this code:
if(openFileDialog1->ShowDialog() == System::Windows::Forms::DialogResult::OK)
{
System::IO::Path::GetDirectoryName(openFileDialog1->FileName);
MessageBox::Show(openFileDialog1->FileName, "Directory");
}
How can i store/write the result presenting in MessageBox to a file called "c:\path.txt",
instead of presenting the result in the MessageBox?
I would be eternally grateful for your help!
Assign the result to a string var rather than showing in a message box.
Create and open a file object.
Write the contents of the string var to the file.
Close the file object.
How do i do that?
This is what i was trying to do:
What is wrong with my code?
if(openFileDialog1->ShowDialog() == System::Windows::Forms::DialogResult::OK)
{
String^ path = System::IO::Path::GetDirectoryName(openFileDialog1->FileName);
fstream File;
File.open("c:\\path.txt", ios::out);
if (File.is_open ())
{
for (int i = 0; i <= 50; i++)
File<< path[i] << endl;
}
File.close();
}
I get the error:
An unhandled exception of type 'System.IndexOutOfRangeException' occurred in myapp.exe
Additional information: Index out of limits for the matrix
Very well.
Problem is solved.
I just have do do this:
System::IO::File::WriteAllText("c:\\path.txt", openFileDialog1->FileName);
