I am trying to make an Image wrapper class or something. The reason for this is that I need to output a bunch of images only, without pictureboxes. I don't want an imagelist, because I need the images along with their associated image properties which an imagelist cannot provide. I ended up with this :

I have some code that allows the user to browse for an image and then when that image is opened, it is copied to a new directory. This all works fine, but I would like to know if there is a way to create a thumbnail of this image and save it into a subdirectory inside the directory where the original image has already been copied?

I have a listbox with several list items added. I want that as user click on an item, I should be able to show its property. This should change for different items. For example (hypothetical) : Listbox has numbers 1 - 10. Now when I select 1 I should be able to set property - Name, Lastname, Colour, Age.
When I select 2 I should be able to set - Age, Hair Colour (clr shows), Weight, Date. When I select 3 then - City (combo box drop down), Country, Age only. This way value changes for diff items. One way is to put them in property grid and show them. Though this looks nice but adding/removing items in that is not easy. You need to have a class that refer that to prop grid. Do I have to code for each classes for all values in listbox or is there an easier way to manage items in property grid. If you think prop grid is not the right tool for such an activity then can you suggest something else.

View 8 RepliesI'm trying to make a program where I draw an image from a SpriteID. The way I usually do this with a method is by doing this:PictureBox1.Image - Util.SpriteReader.GetSpriteImage(2334)
This works fine, but I need to make it work through a Bindingsource and my class. So the Bindingsource is setup, everything is working but the image part. I set the "Image" in the DataBinding of the picturebox to my "Image" property... Heres my properties

Public _Image as Image
Public Property ItemID() As Integer

I'm trying use just a user control form to act like the old VB6 picturebox. Mainly, i'm doing this is because a user control form is also a container but i also want it to have an image property. I've done this. The new control does have an Image property but the problem is that the user control form doesn't have an image property but only a BackgroundImage property.I was hoping that there is some way to place the selected image, directly on the surface of the user control and not to it's BackgroundImage property. Here is what is got so far:
Code:
Public Property Image As System.Drawing.Image
Get
Return Me.BackgroundImage
End Get
[code]....
As you can see, for now, i have to use the BackgroundImage property but i want to image to be placed on the controls surface, so that the image can be manipulated, like drawing game tiles on it or image processing. The user control doesn't have a real image property?
I am using images imported into My.Resources as images for items in my game. Now for the saving procedure I use pnl.BackgroundImage.ToString but that returns System.Drawing.Image. What I'd like to know is how to retrieve the name of the resources object that is the image of the panel.

View 4 RepliesI am just wondering what was the use of tag property in VB.Net....
I am planning to make a system wherein i can add tags to images so that if i search in my computer, all images tagged in same keywords will be displayed..
For example i open an image to my system, and it's file name was "WhiteHouse.jpg" and i added or tagged it as "Building". Once i search on my computer, and type the word/keyword "Building", the image "WhiteHouse.jpg" will be displayed on search results as i tagged it on my system.
if the TAG PROPERTY in VB.Net can make this thing., How can i save the images together with this tags?
I am in the process of creating a relatively simple "yahtzee" game for a final class project. I have a "Roll the dice" button on my form that when clicked chooses 4 random numbers 1-6.

A series of If then statements is being used for each picture box so that for example The random number is 1, a image of a dice facing the 1 side is displayed.[code]...
View 5 RepliesI added 7 bmp files in the Resources tab of the Project Properties I have 7 PictureBox controls, for each control I set the Image property to a certain bmp saved in the Resource section.Everything was fine, however all of a sudden I got this warning message for each PictureBox
"The type 'My.Resources.Resources' has no property named 'lla_nodev'."lla_nodev represents the "lla_nodev.bmp" file I added in the Resource The worst thing is that the Form is unabel to load in the designer view, so cannot I modify it. The application is able to run though,with apparantely no problems in run time.
I am trying to work out a method to reset the image property of my picturebox on the fly.

I am writing a VB 2008 Express Edition application which has multiple forms. All of the forms contain one or more PictureBox controls. All PictureBox controls have assigned bitmaps via Image property during development mode. So far, all the bitmaps displayed during runtime without a slightest problem. Now, suddenly, not a single new one (i.e. which I add from this moment on) would display bitmap during runtime. All the old ones (i.e. those which I have added up to that unspecified point in time when something went wrong) still display bitmaps fine as they did before. But any newly added PictureBox (or, come to that, any other control which can display bitmap.
I have tried also Label control) displays the bitmap loaded via Image property only during development mode. During runtime the PictureBox shows as empty. I tried to load the bitmap during runtime via command Image.FromFile and that works fine (but I don't want to use this approach in my program). If I create a completely new application, all PictureBox controls display the bitmaps just fine. I don't get any errors or warnings in VB editor. I reinstalled the whole VB 2008 Express Edition including SP1 and .NET 3.5 SP1 with no difference whatsoever (as would be expected as any new application works with PictureBox controls fine).
