C# need help
The idea is to check if the user entered a name. If he didn't, alert the user that he didn't do so. Currently it's giving me this error...
\MainForm.cs(94,7): error CS0122: 'System.Windows.Forms.Control.text' is inaccessible due to its protection level
The field 'text' is the private or protected backer of the 'Text' property. You need the property, thus 'Text'. Watch the uppercase T!
Change
to
Change
if (tbName.text == "")
to
if (tbName.Text == "")
Looking at your recent topics, have you made a switch from C++/Win32 to .NET? If so, and also if not so, good luck with .NET :)
