After a path is defined with all its components, is there a version of the DrawPath that allows the composite object to be drawn in locations other than the initial locationsFor example, the code shown below displays an ellipse and two rectangles in a specificocation. To also display the same objects in one or more other location,s, is it possible to disply the defined path at other locations or is it necessary
View 2 RepliesProblem drawing dotted path lines, with even dots along the path line.I want to draw a path line that can be any shape (square, round, outline etc), and along this path line I want even dots to appear.
I also want to be able to resize the shape (as in the example attached)This is very easy to do using "DrawPath" and defining points for the path and using a pen defined as dots.The problem I have is I want the dots to be evenly placed along the path, on any shape or size I draw.In the example I have created, I create a square with 4 points and draw a dotted path.There are 2 buttons that allows me to resize the square (larger or smaller) this helps show the problem more clearly.
The path starts at the top left corner and finishes back at the top left corner, the dots are evenly placed along the path, except the final dots at the end of the path. (Sometimes the dots are even and other times they are not even).The shapes I want to draw can be any size and any shape, but I have used a square in this example to show the problem I have. point me in the direction I need to go that allows me to draw the dots and give the impression that they are even all along the path, for all shapes and sizes.
In the pictures below if you change the size of the shape, one will have even looking dots, the other will not.

What I want to do is when I click on each grid on the form (Touch Screen), a tooltip of some stored information about the grid appears on screen.

I have a problem drawing dotted path lines, with evenly spaced dots: I want to be able to draw evenly spaced dots along a path line using points in an array, My issue is not with drawing the path line, with dotted lines, this is easy, but with the spacing of the dots at the start and end of the path line.

View 2 RepliesI 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

View 3 RepliesThe file locations for a setup package using Standard Edition? I have added an .xls file to my project, marked it as Content and as Copy Always in the properties for that file. The XLS file I added to the project is from my user Apps folder in the Roaming sub folder. Other simple .TXT files are in my UserMy DocumentsData folder and each file is also maked as Content and Copy Always. When I create the setup package all goes well. I have a setup.exe and an .msi file. When I test it by installing it on my PC of course the program knows where the files are because it's my PC. In the program folder created as C:Program FilesMyProgram I find the .exe plus the XLS and TXT files, but these XLS and TXT files are not used from the program folder. How might I know if an installation made by another user on another PC elsewhere is going to load files in their user apps or user documents? I need to be sure that the additional data files deploy to the correct location (whatever I want that to be) on a remote PC.

View 3 RepliesI have a collection of locations for a sales person, allowing them to send an item to multiple locations. I want to start reading at index 1 since I am using a collection. I saw an example where you can say something like "+ 1" (e.g. myitem.SelectedIndex + 1) to skip the first record. How can I skip the first record for the following:
Public ReadOnly Property Customer() As ICustomer
Get
Return CType(Me.CustomerList.Item(Me.CustomerNumSelected), ICustomer)
End Get
End Property
I tried to say Return CType(Me.CustomerList.Item(Me.CustomerNumSelected + 1), ICustomer) but it returns an error saying "string cannot be converted to a double". without the + 1 in there, I get an error that says "collection index must be in range 1 to size of collection".

How can I assign a variable preferably an integer for each slot so when the dice is rolled I can just do a little addition as to where the markers can be moved?
