I've built a dialogbox with a RichTextBox and I'd like to have the following behaviour:
I've got the focus (cursor) in the RichTextBox. When the ENTER key is pressed, then there should be a new line in the rich edit control created. The ENTER should NOT close the dialog box [as it does now :-( ].

I am new to vb.net, from VB6. Trying to understand drawing a simple line graph into a picturebox, which was so simple in VB6 ! From code snippets, I can see the basic idea using an bitimage to draw the lines and then showing it in a picturebox. I don't understand how to (simulate) scaling of the bitmap's x/y scales like you could do with VB6's .Scale.

VB 6 has a ScaleHeight and ScaleWidth property which VB 2008 does not support and this is causing me fits to work around. I'm trying to draw some lines (a graph) on a Picture Box (or a Panel) using my own coordinates (not pixels). This can't be all that hard can it?

My problem is centering the 0,0 points of my graph to the center of my picturebox
Dim picBoxWidth As Integer = picGraf.Size.Width
Dim picBoxHeight As Integer = picGraf.Size.Height
Dim halfWidth As Integer = picGraf.Size.Width / 2
[code]....
So how to I tell it to start at the center of my picturebox names (picgraf) btw.

ReDim dataGraph(2, UPPER + 1)
Chart1.Series.Add("Series1")
Chart1.Series.Add("Series2")

using vs2008 I am trying to create a line graph using vb in a windows form. I have dragged a chart onto the form, and via the properties window, through the series option have changed the type to the graph that I want, which is line. But all the time the data is displayed as a simple bar chart. How do I remedy this please to get the type of chart that I want.

I've looked around, I can't find much documentation on Line Graphs using the MS Chart Addon for VB2008.
Whenever I add the "chart" control (which seems to be the only new one in the property browser) a Bar Graph appears. I'd like to create a line graph rather than a bar graph, I don't see an option to change the kind of graph it displays. I'm sure I'm missing something simple, since I've seen people able to create their line graphs almost immediately after installing the control.

I am trying to plot a set of data using a function I have defined as an array:
Private Sub calculate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles calculate.Click
range(1) = min.Text
For i = 2 To 100

Range(i) I want to be my x values and fee(i) to be the y values. When I try to select range() and fee() as the x and y values for a series, I get an error because they are not of type double.

I would like to know a simple method to create a simple line graph, with a grid and X and Y values... I tried just drawing in a picturebox but that was just annoying and not clear... Is there any simple way to create a little graph with prefixed values on X and Y (graph should just be lines drawns from different Y values, with always the same change of X)

I'd like to do something I thought was simple. All I'd like is to take the data from a connected database, then put those values into a scrolling line graph. Preferabley with 4 lines (taking information from separate tables) on the same graph. I've connected the database and set up a script to populate it with data, but that's as far as I go with graphs.
I've downloaded 'MSChart.exe', 'MSChart_VisalStudioAddOn.exe', ChartFXLiteNet' and others, yet none work. I've also followed a tutorial here on graphs, but it's for visual studio 2005, and I don't have the options required. I'm using Visual Studio 2008 with VB.NET.
