View 1 Replies.net - Given A Large Number Of Objects, Create Multiple Forms In Designer For Them Or Use Code To Create The Forms?
Dec 29, 2010If I have a large number of classes, each similar to the other in certain aspects (they all share a common base class, but each does things differently), and I need to create Windows forms for each to allow easy changing of their values through a GUI? Create one matching form for each object in VS' forms designer, Or Use code to create the forms dynamically at runtime.
#2 makes the most sense to me, because a lot of these objects will share very common features of the form, notably "Ok" and "Cancel" buttons. But one object might need to draw a textbox on the form while another might need to draw a combobox. Not to mention, if I want to put icons on the "Ok" and "Cancel" buttons, I'd have to do this for each copy of the form in designer, and that sounds like it could get out of hand quickly.But is drawing forms through code sane? VS' forms designer is pretty sophisticated and designed to make life easier. Am I wise to consider ignoring its functionality and diving into the trench warfare of forms design through code? Or are there examples of automating form creation based on an existing object's properties?

I'm using a date/time picker control and sending the db value to it. I know that the value is null, but I don't understand why the Picker can't be blank. Is there a way to let it be blank? Or should I set up a way to check for nulls and assign today's date or something just in case?

View 3 RepliesHow To Create Actual 'wizard' That Allows Users To Use It To Create Their Own Forms
Dec 1, 2010I've designed my own encryption application in VB 2008 that has a free tools section where users can choose a particular wizard to use from the drop down. The javascript wizards display the code required to put in their own sites. I already created wizards that users can well, use.I see people have their own "contact form wizards" on their websites all the time. Where users can use the wizard and get the displayed code to copy and paste on their sites. But trying to locate source codes to these things is very aggravating on the web.So what I want to do is create my own "form wizard" like out of javascript, that allows the user to put in some information then get the displayed code to put in their own websites. I'm not looking for the generator such as the online form generators.But the javascript source code(s) for the generator itself.Then I could simply put a form generator inside of my VB-app, that will allow the user to use the wizard, then get the html code to paste in their own sites. Preferably not the PHP one because the php backend is very difficult to put in a VB app.I know that it can be done. For example copying a web pages source code then putting it inside a string, then calling that string from a button click that will open the javascript page in the webbrowser inside the VB app.
