View 5 RepliesI would like my forms to open as part of a "bigger" program, where there is a screen that fills the monitor and inside this screen is my form, centered. When a new form is opened, only the new form will be displayed...it will not be form on top of form.It would look similar to the screen in the following link, except the form inside the bigger screen would not have the minimize, maximize, or close buttons.I am just wondering if there is a property in VB.NET forms that will allow this to happen.

Basically, I have a large number of text boxes. Within these text boxes, I'll be doing calculations based on user input and other things. These boxes will be grouped by numbers, eg Cost1, Profit1, Stock1... Cost26, Profit26, Stock26. Without too much explanation, I went to write a FOR loop to perform a repetitive calculation across multiple groups, and the following line came up.
FOR num = 1 TO 26
Cost(num).text = ItemCost
What I've tried to do is use a variable to decide which 'Cost' textbox, from the available 26, to use in the calculation. For whatever reason, it won't work. I would like to be able to use a variable to specify exactly which textboxes I want used, so that on the 3rd pass of the loop, the 3rd box is used, and on the 19th pass, the 19th box is used. Otherwise, I'd just have to do each calculation separately, and write the same thing 26 times, with slightly different numbers.
During runtime, while (hehe...pun ) doing some operations, part of my windows form turns white, and the buttons don't show, and it doesn't look so user friendly.I am running some processes and I wonder if If its because I am not using the process.waitForExit() function, and I have quite a number of loops...
