I want to know if it possible to use tabs (like Google Chrome or many others program) in VS Express 2010 to swap between forms without closing any window.
I know there is the tab control item in the tool box but as far as I know you need to create the tab content in the same form. I'm looking for a way to swap between form like if I put Buttons in the the top of each form (workers, customers, ext) that open the form I clicked and close the one I'm in but not change the main window.
You can use MDI parent method. If I understand rightly, this link will help you.
OR
You want it to be in the same window.
Add this code
this.IsMdiContainer = true;
to main form.Create new form for every menu or button click.
Create this function and call every button click for make to hide all form
After that button1, button2,... click event
