View 6 RepliesLoading A Picture Into A Picture Box Control?
Mar 15, 2011My plan is to use a database to hold her recipes and create a user interface with search controls and different stuff, this way she will be able to add new recipe's and the program will have a much more modern feel to it.
My question is, I have added a picture box control to the new recipe form and when I click on the picture box I want the program to load "my pictures" and let me select a picture to load into the picture box, like you can on ebay when you are selling stuff, you can select your picture and it loads into the picture box.
As far as starting this off, I can add a double click event on the picture box control, this will trigger whatever code I need to use to load the open file dialog.
Can I use simaler code that I used for a text editor program I wrote for opening saved documents?

ListBox With Alternate Row Colors
Nov 19, 2011I know how to have alternate row colors with ListView. But how about with ListBox? I've run a search. I read in some web sites where they say you can't. Is that true? Meanwhile, I've done something like:
For i As Integer = 0 To ListBox1.Items.Count - 1 Step 1
If i Mod 2 = 0 Then
ListBox1. BackColor = Color.FromArgb(150, 250, 255)
Else
ListBox1. BackColor = Color.White
End If
Next i
with ListBox's DrawItem event. And it doesn't work.

Reducing The Number Of Colors In An Image?
Dec 23, 2011In the process of creating an Icon object, I need to reduce the numbers of colors in an image from thousands down to 256 or less. I do this by "chromatizing" the RGB values - counting the colors - then re-iterating the process with heavier "chromatization" until the number of colors is reduced to my requirement.
I searched these forums and google on this subject to find out more - but I found that I alone call this process "chromatization" it seems. So I was hoping someone could help me out with the correct terminology.
Specifically, I want to use the correct terminology on my UI buttons (at present I have a button labeled [Chromatize] . .) and I am curious as to whether it would be good practice to "chromatize" the Green most heavily, the Red more moderately, and the Blue least . . . or just "chromatize" them all equally which is what I have been doing

VS 2008 - Image Transparency - Loading A Bunch Of Pictures On Top Of One Image
Oct 14, 2009Ive been programming in VB6 for years, i figured its time for an upgrade. Here's what im doing, and what the problem is:
Im loading a bunch of pictures on top of one image. They are all PNG files, and some of the images have transparent edges, and some semi-transparency within the image itself.
So basically, i need to be able to load these images on top of the other images, and still maintain the transparency.
Is this possible in VB08? This is one of the main reasons i moved to 08 from vb6, more things possible including multithreading.

Loading Images From Resource Into ImageList?

Is there an easier way to do this than having 100 lines of code, like the small example below?
imgItems.Images.Add("A", My.Resources.A)
imgItems.Images.Add("B", My.Resources.B)
imgItems.Images.Add("C", My.Resources.C)
