VS 2008 Woodcutting Program / Draw Image & Save Cuts
Jan 27, 2010
I'm currently working on a VB 2008 course of Michael Halverson, and I'm stuck at an assignment where I'll have to expand a previous wood order program so customers can add woodcuts to their orderIn the newer program a customer can define 4 coordinates (x & y for startpoint and x & y for endingpoint), after clicking on the button 'Next cut' a line will be drawn on screen (in PanelCuts) with a maximum of ten lines. After finishing, the coordinates must be saved in the order.txt, and when the client re-select the order in the main order program, they can review and adjust / remove the already specified cuts.Right now I'm at the point that the you can enter the coordinates, and the line will be drawn.
- What's the best way to store the submitted cuts, in a Label? array? or something else?
- When the form reloads, how to displays all previous made cuts? Can i count the numer of cuts and with For i = 1 to combined with SelectedItem. Split() ? [code]

I'd like to draw an image (like a bar code) pixel-by-pixel in a Visual Basic .NET WPF Application and ...
show the image in my UI
copy it to the clipboard
save it as a .BMP-File.
It should also be possible to add Paint-like editing features later.What is a good approach? System.Drawing.Bitmap works internally, but the only way I could show it is to convert it to an ImageSource and show it inside an Image control. Is there any better way?

I'm making a front end to dvdauthor.I have a picturebox which holds the menu background. In order to draw a textbutton on the background image I store the image in a hidden picturebox. So the text doesn't get drawn to the visible background.
Dim ctl As Control
For Each c As Control In pbMenu1.Controls
If c.GetType() Is GetType(TextBtn) Then[code]...
This works the first time. But if I hit save again it writes the text to the background image on pbMenu1.

I am trying to make it so that my form application can have hot links to any other program on your computer by simply having the user input the target path of the program and also save that so the user does not have to do it all over again every time.

I want to draw an image onto another image object but use an alphamask specified from another image that is grayscale.
I am drawing an animation manually so don't want to do this pixel by pixel as this would be extremely inefficient.

I want to know if there's a faster way to draw images onto a picturebox based on a list of point.
vb
Dim MyPoints as New List(Of Point)
Dim MyBitmap as New Bitmap("C:MyBitmap.PNG")
[code]....
Now, This code may be a little sloppy, but I just put it together. The image isn't very simple, but it's simple enough. After about 10 images that need to be drawn, it starts to get slow.What would I need to do to ensure it draws the images faster? If I made the image itself smaller would it make it go faster?

I assume that this will be an easy one for you guys. I have never dabbled with drawing in VB.NET. I have searched the forum and Google already, but have turned up nothing to help me. Here is my problem. I have an image that is in an image box. I would like to draw a string of text on it, centered vertically and horizontally. Here is what I am using to draw the text.

I know that you can pass a Point array to the DrawImage method of the Graphics object to apply rotation, skewing and flipping, but I'm having trouble figuring out how to calculate the rotation. So far I've got:
Dim radius As Integer = Math.Sqrt((rect.Width / 2) ^ 2 + (rect.Height / 2) ^ 2)
Dim dX As Integer = RadToDeg(Math.Cos(DegToRad(angle))) * radius
Dim dY As Integer = RadToDeg(Math.Tan(DegToRad(angle))) * dX
Dim new_upper_left_corner As New Point(rect.X + (rect.Width 2) - dX, rect.Y + (rect.Height 2) - dY)
This is all just off the top of my head so far, I'm not sure if it's right. How do I calculate the other points on the rectangle, and is there a built-in VB.NET method that's much easier? (Apart from Graphics.RotateTransform, which is slow and also rotates around 0,0.)

I have a problem with saving images in Access. OK the problem is: I saving for first a picture without problems, but then I want to change it for instance "I don't like this image and I want to change another one". Access doesn't want to save second image... and I don't understand way! Code is OK I think because it saved one image. I can change the previous image only if I closing the program and I start it again.[code]...

This has really been a problem for me in the past and with deadlines, we decided to just have the app copy the image to the server, rename it and save the link in the database. This is the worst way of saving that kind of sensitive data, I know. We now have the time to fix that.
