I'd like to know how I can craete new forms at runtime.
Lets say I press Command1, a new form would open with a text box and a button on it. If I click Command1 again, another form would open with a textbox and a command button.
Background: ok I have an app that hides in the system tray. During its operations in the background it can try to invoke an outside app several times.. and I need to track when the call errors out.. I was using messagebox's but for some reason if the app hidden the messagebox's dont come up and goto the forefront. So in reading about this I read I should just use a form to do it.. so I did.. works fine.. well works fine for one error.. but if the user tries to do 3 of the same operation.. and lets say first errors.. second works and third fails.. using one error form wont work.. since I diaplay the error one.. then need to display error 2.. I need 2 error forms so they can click OK on both.[code]...
View 2 RepliesTrying to create an application where the objects in a form are created during Form.Load depending on the content in an ini-file.The objects I have in mind are textboxes and labels for a start.
View 5 RepliesI have a form that depending on results from a table would create a number of buttons using code at runtime. This could range from 1 to 20 buttons. What I am struggling with is creating a generic mouse over event for each of these buttons? The reason why I want a generic mouseover event is that depending on the text on the button I would do certain things, instead of duplicating the same code in individual mouseover events. I am writing in VB.Net.
View 1 RepliesIf 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 use VB. NET 2008. I'm starting to work with the Tab Control and command will want to know about techniques such as adding tabs at runtime using this control.
To illustrate what I'm saying, just take one checked on your browser or in the VB (Start Page, when we add other forms to our project).
But why can't I figure out how to get one of any number of created WebBrowser controls to navigate to a website?I have a FORM a BUTTON and TWO TEXTBOX controls at design time. I run the program and it creates a random number of WEBBROWSER controls named WebBrowser1 to WebBrowser whatever.textbox1.text = a number, 1 - max number of created webbrowsers, determined in whatever way it is. but what if textbox1.text could equal 35, or 1, or whatever. HOW DO I REFERENCE IT'S ASSOCIATED WEBBROWSER CONTROL?!?!?I've spent a few hours researching this and I find page after page on creating controls, but I can't change the data of a control determined at run time, and I can't find how to anywhere.

View 1 RepliesI can build the tabstrip fine and name it - that part is from what I can see the easy bit.What I want to do is select a tab then create a listbox on that tab, and then pupulate the list box with data.

The system loades the logs into memory, and then creates however many system logs there are ie application, system security etc etc.
But how the hell do I select one of these tabs then draw a listbox and then address the list box - Ideally the list boxes etc will be created at the time of the tab?[code]...
