View 2 RepliesVS 2008 - Linq Statement To Go Through A Dropdown Menu's Sub Items And Get What Items Are Checked
Apr 8, 2010I have the following linq statement to go through a dropdown menu's sub items and get what items are checked: vb Dim UnselectedItems = From xItem As ToolStripMenuItem In tsiSelectObjects.DropDownItems Where TypeOf xItem Is ToolStripMenuItem AndAlso CType(xItem, ToolStripMenuItem).Checked = False
I get this error tho: Unable to cast object of type 'System.Windows.Forms.ToolStripSeparator' to type 'System.Windows.Forms.ToolStripMenuItem'. As you can probably guess i have ToolStripMenuItems and separators in there
However the AndAlso should short circuit in the case where the item is not a ToolStripMenuItem and it doesn't seem to be doing so (as TypeOf xItem Is ToolStripMenuItem=false in this case)?

VS 2008 Drawing 'arc'?
Aug 19, 2009I have a little experience with drawing using GDI+ in VB.NET, but not so much with more complex shapes. All I ever used were lines and rectangles, and the occasional ellipse.I need to draw an 'arc' like this:I can specify the starting angle (0 in the picture), ending angle (angle from the horizontal (left side)), and the starting and ending radius, and I'm sure any other things I need can be calculated from that.The problem is that I have no clue which drawing function to use. Can I do it using FillPath, or FillClosedCurve, or? Of course, I could create a pie shape and then draw a second pie shape (slightly less radius) on top of that to make it appear like it's a single shape, but what if it needs to be 'transparent'? I don't want it to draw a solid shape on top.
View 17 RepliesDrawing On Picturebox Vs Drawing On Form?
Feb 18, 2012I need some code to draw a resizable, draggable rectangular cursor (or selection box) on a picturebox. I found some excellent code (albeit rather old) that does just that, but on a form rather than a picturebox. I have tried converting the code - basically moving things to the picturebox events (Paint, MouseDown, MouseMove etc). It nearly works but leaves a trail behind it when you move or resize the cursor. In other words, the selection rectangle is not being erased before being drawn in the new position.
Is there some fundamental difference between drawing graphics on a form and drawing on a picturebox that would cause this behaviour? Something like, when you invalidate a form and cause a redraw it erases what you did last? If not, then I just need to dig a bit further and work out how the cursor is being erased from the previous position.
Here's the original code that works fine on a form:
Private DragRect As New RectangleF(20, 20, 100, 80)
Private Adornments(7) As RectangleF
Private MouseInRect As Boolean = False

VS 2008 Graph Drawing
Sep 30, 2009my assignment is to draw a graph within my VB form with a some variables I have. I was told by my boss that I should use Microsoft Chart Control 6.0, but I don't think it matters if it is in another software.I currently have a few variables, each with a lot of values, "Frequency", which is user entered from maximum to minimum, CH (channel) 1-4 which are given by a machine output I use at my company. My graph, is supposed to have the Frequency values in the X-Axis (horizontal) and the CH 1-4 values within a range of each other in the Y-Axis. Can anybody help? My code for extracting the data and getting the frequency is below. How I got most of it is thanks to Stanav, the thread is over here: url...It comes with 3 buttons (I have not put in the code for button 3), the 3rd button will be used for plotting the graph when clicked.
