I am creating a gridview and need to gather the data from various functions that return a type of IEnumerable. I've created gridviews using a dataset as a datasource, but how does one use multiple data sources(of IEnumerable) to populate one gridview? Like how do you combine all that into one dataset?

I am trying to create a simply bouncy ball application in VB net; I am using a timer and the FillEllipse() method to try ad create a new circle at every tick of the timer.
Code:
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Dim Gr As Graphics = Me.CreateGraphics
Gr.FillEllipse(Brushes.Teal, X, Y, W, H)
CollisionDetect()
X = X + X_Dir
Y = Y + Y_Dir
Gr.Dispose()
End Sub
The result? The form continously draws onto itself, without clearing the last circle. This means that you end up with a 'line' of spheres together.
To clarify:
X is well, the X-Coords
Y is Y- Y-Coords
X_Dir is an integer, it is added to every iteration of the loop so the next time the loop iterates, it'll be at a different location;
Y_Dir is the same but for the Y Coords;
CollisionDetect() Is empty. It is yet to be filled, it will handle the collision with the sides of the forms. W, H are width and height, respectively.
I have to make a program in my class that will tell you the correct change due and the number of each coin/dollar you should receive after entering the amount of money due and the amount of money given. On the form it should have a Calculate button, Clear button, and a Quit Button. The Calculate button should, of course, do the calculations. The Clear button should Clear the text boxes and labels to as if you just started the program. The final button, the Quit button should exit the program. I have Programed the Calculation button and the Quit button but I am unsure on how to program the Clear button. We have been shown how to program the first two buttons but not the third. I would think the programming would be somewhat similar to the programming for the Quit button "Application Exit ()" but I can not figure out exactly what put.

I have a mainForm with a DataGridView control. This DataGridView is not bound to any datasource. All Rows and Columns were added. On another Form, I have a button. When I click it I want the DataGridView to clear all rows.
Does not work, in button click event:
Form1.DatagridView1.rows.clear
Also does not work:
A "Public Sub" on the first form, invoked by the button press - so the change is made within the same form.
I am trying to use the same form for several functions which means I have to change the properties. In order to do this, I was trying to put a select case in a module that could be recalled anywhere in the project.
As soon as I start a select case in a module, I get an error message "Error1Statement cannot appear outside of a method body." Does that require that it be in a form only and cannot be used in a module?

View 4 RepliesI have a Main form that loads 8 picture boxes. Each picture box is the logo of a different game. What I would like to know. Is there a way to clear the Main form, output text AND load 2 more picture boxes (to indicate whether to go back to the main form or quit the program)? or would I have to make a new form for each game? I can't seem to find the syntax for "CLS" (clear screen).
View 4 RepliesI guess, I am in some kind of trivial problem. Here is the scenario, I have a Form which has 3 main control two buttons "Button1" and "Button2" and 1 tab page control with two tab pages "Tab1" & "Tab2". Now Tab1 has one textbox controlled say "TextBox1" and one check box "chkBOX". What I am trying to do is, when I click Button1, only one tab page i.e Tab1 should be visible. Which I done using ".Clear" and ".Add" and is working fine. And now when I click on Button2, it should display the text in TextBox1, for this I have used:
msgbox(TextBox1.Tex)
Till now it is working fine. But when ever I use msgbox (chkBOX.checkstate), it displays 0, irrespective of control being checked or not.
I have used many of the controls in vb.net forms, including a textbox and combobox, but I want to clear all my text boxes at once, while not typing textbox1.clear() for each one. Is there any other way to clear all my textboxes?

View 4 RepliesI have a reset button created in my VB form, but don't know how to code it so that it will accomplish what I want. I want it to clear the form's text boxes so that new input can be entered. I could just code an end statement but this closes the form, and I want to keep it open to continue working with it.
View 6 RepliesI have several forms that are "reused," or vistited more than once per each time in the whole program. In VB6, using Form.Show() would show the form in its original state (the state is was when created in the designer). After closing this form (Unload Me), showing it again would still show the form in its original state.
I am coding in VB.NET 2008, and noticed that when I reopen a form I had closed during a session using my program, the form is in the state it was when I closed it (labels and listboxes filled with data), and not in its original state. I currently have the Form.Closing event filled with code to clear all of the controls, but I think that there must be a better way to "clear" or "reset" the form.
I have a small script that logs all of the website I visit and then displays them on a form. When I open the form the first time it displays all of the websites like it should. However, the second time I open it, it displays two of every website. The third time opening it, three of every website. I think that it is because the data doesn't get erased from the listbox when I close the form. Is there a way to clear the listbox when the form closes or do I need to find a new way to set it up?
