First of all, I will not GIVE you any code. I will however try to help you on your way. The textbox is the wrong control for this. You should use a richtextbox. Look here[^] Especially have a look at the properties SelectionColor, SelectionStart, SelectionLength, ... Hope this helps. V.

On the first menu tab page, I update the 'main'table with default values and values the user enters. The user clicks the next button the user is allowed to change some values based upon when customers submitted work. Basically some of the dates that are loaded on the first page come off of a schedule due date table. If the customer submits various parts of the paperwork late, the user changes the dates in the database. So the question is if a date was loaded into a sql server 2008 r2 datqabase, and the user finds that they need to change the value to NULL is that allowed? Basically on some of the paperwork that is supplied by the customer if they do not supply a date, the data needs to be set to NULL. Thus in the application how do I pass the null value to the database via the datacontext object? Do I pass the value as '' or 'NULL', or some other value? Thus can you tell me how to pass this Null value to the appropriate column in the database?

Re: How i Can open my c# form only automatically to user when user open windows. Richard MacCutchan22-Nov-11 3:40 Richard MacCutchan 22-Nov-11 3:40  You will probably need to add it to the registry in HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run. But you may find that your users have their own ideas as to whether they want this to happen or not. Unrequited desire is character building.

Pour water into the cooling fans, turn it on and BAM!!! faster computer along with the use of the program in all users YOUR WELCOME!!!!

Clark Kent12322-Nov-11 9:43 Clark Kent123 22-Nov-11 9:43  I agree with others with either using the Registry and StartUp folder. However, there is also one more alternative if not more to consider. Why not try creating a Service? Here is an article to get you started. MSDN: Walkthrough: Creating a Windows Service Application Once that is done you can go to the Component Services and set the application to start once the computer has turned on. There is also very cool recovery options. (dcomcnfg) Hope this helps! Re: How i Can open my c# form only automatically to user when user open windows. Mark Salsbery22-Nov-11 9:47 Mark Salsbery 22-Nov-11 9:47  Services shouldn't be interacting with the desktop, so not a great idea for a "form" app Mark Salsbery Re: How i Can open my c# form only automatically to user when user open windows. Clark Kent12322-Nov-11 10:05 Clark Kent123 22-Nov-11 10:05  Depends Mark upon what the developer is trying to achieve. Hence, the reason why I chose the suggestion icon. Just another option to consider that's all I was trying to get at. I don't know the specifics of what the developer is hoping to accomplish with the "form" app. Thanks for the feedback.

Dave Kreskowiak22-Nov-11 19:13 Dave Kreskowiak 22-Nov-11 19:13  Under Windows 7, a service cannot display a Form for security reasons. Well, it could, but at best, it'll show up on a seperate Desktop and the user would be informed that a service is showing something that might need the users attention. If OK'd, it would switch Desktops. This is not something I would use in a production app at all.

BillWoodruff22-Nov-11 15:11 BillWoodruff 22-Nov-11 15:11  The answers here have assumed that you want your application to open automatically when Windows is started. I am wondering if what you are really asking is: how do you open your application when a file with the unique extension you are using for files you save is double-clicked ? Please clarify your question. thanks, Bill "... Sturgeon's revelation. It came to him that Science Fiction is indeed ninety-percent crud, but that also—Eureka!—ninety-percent of everything is crud. All things—cars, books, cheeses, hairstyles, people and pins are, to the expert and discerning eye, crud, except for the acceptable tithe which we each happen to like." early 1950's quote from Venture Sci-Fi Magazine on the origin of Sturgeon's Law, by author Theodore Sturgeon: source Oxford English Dictionary on-line "Word-of-the-Day." KeyPress events in a console window? Member 840468922-Nov-11 1:11 Member 8404689 22-Nov-11 1:11  Venerable coders, How do I connect a key press in a console window to event code? All I've found on a search, thus far, is to put the Console.Read() statement in a loop to catch a key press --non-acceptable. Please share. Koodos, AZdon Re: KeyPress events in a console window? PIEBALDconsult22-Nov-11 2:10 PIEBALDconsult 22-Nov-11 2:10  You'll need a loop regardless, or the program will exit. Edit: I just wrote this... Producing KeyPress events for the Console[^] Re: KeyPress events in a console window? OriginalGriff22-Nov-11 2:14 OriginalGriff 22-Nov-11 2:14  The console does not have the concept of a message queue, so it doesn't really handle events - the only event it publishes is CancelKeyPress[^] However, there is a way to do more. See this article: Console Event Handling[^] Be warned though - it's not for beginners!
