View 2 RepliesAt one point I have a dialog form open, but in order to process it, the user might want to access information on other (open) forms. This would necessitate the ability to move/resize/scroll the other forms, but obviously everything is frozen during the dialog. I don't suppose it's possible to achieve this "semi-modal" state, where other forms can be browsed, but no other actions taken?

How can I update and get values in a Windows Forms application while moving one form to other form (like cookies)?
I need to update the values to some variable and again I am going to refer stored values and need to do some calculations.
I have used cookies in ASP.NET but I am not able to find out the same concept in .NET Windows Forms (C#).
How can these issues be resolves?
I have a question that I hope to find a much more simpler solution to.I have two forms in my program which are named Main and Second. The Second form has several textboxs, buttons (some disabled) and comboboxes. When the Second form is opened via the Main form on the very first instance, everything works fine.
However, if I re-open the Second form after previously closing it, the disabled buttons are no longer disabled and the text controls and comboboxes show the previous values entered from the first instance which I do not want. How can I ensure that the Second form will be opened "clean" every time.
Currently I have to add instances to the onload event to do this to ensure that the form is cleared on the second instance.textbox1.text = ""textbox2.text = ""textbox3.text = ""button1.enabled = False
I have a small "options" form that when shown, the user submits some changes, clicks a button, and then it fades out. I want the form to open at the mouse location. How would I do that?
