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 am working on a personal project, and I've been looking at a way to make an application where you can enter in the other user's IP address, load a picture into a picturebox and have it appear in the other user's picturebox, on a separate computer. I am not looking for code, but examples are welcome. I would just like a nudge in the right direction.I've already looked at P2P and winsock, but I cannot figure it out...

View 3 RepliesBasically I want to have a picturebox which shows an embedded resource if not connected to the internet, and an online image if connected to the internet.I assume this can be done on the form load event, I just don't know the code for it. Basically this is the logic though:
-If 'http:/[url].... is available (therefore connected to internet)
-Picturebox1.Image = http:[url].....
-Else[code].....
How can I code that properly? Would putting it in the form load event work?

I am trying to control the Stretch property of an Image object in VB (using Visual Studio 2008 if it matters.)Is there a way to do this with VB code?I have added the Presentation Framework reference to the project.I can create a variable to point to an image using dim imgName as Image = Image.fromfile("filename.jpg").After I declare the variable, I can imgName. and get a whole list of properties, but Stretch isn't there.
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 _ItemID As Integer
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.

Is there a way I can customly add to the MainMenu control to give the child image property like you would see in a menuStrip? Where you can have drop down's with images next to the text?
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. Each number is a seperate "dice", each of the 4 pictureBoxes is meant to represent a seperate dice. 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 want to use SetPropertyItem to add a new property to an image ...
how can i create a new System.Drawing.Imaging.PropertyItem without first reading a property from an image and changing its values? as this seems somewhat counter-productive
I am trying to work out a method to reset the image property of my picturebox on the fly.
I am able to load the original image from a file. But i want to save a clean copy of it before i draw on it. Between drawings i want to be able to reload it.
Here is what i have tried
Dim img as image
Using OpenFileDialog1 As New OpenFileDialog
With OpenFileDialog1
[Code]....
the code does not seem to work it just freezes. Im not sure exactly whats going on with it.
I am getting a "Parameter is not valid " error when reading a value from an Image property and I don't know why.
Writing to the property works just fine (MyControl.EditImage = PictureBox1.Image) .
Reading from the property causes an error (PictureBox1.Image = MyControl.EditImage )
The Property looks like:
Private mNewImage As Image
Public Property EditImage() As Image
Get

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).
I need a Class with Image Property, and then have a list of that class to populate a datagridview. Questions:

But when I view myQ at a later date it tells me the parameters of the images are not valid.Is it adding them by reference?i would have through adding an object to a queue was byval. how can i enforce this?
we have our system running but our system needs to be modified because we did something wrong...we are doing an "Internet monitoring System" in our school library where the user can only access the internet 1hr a day, and he/she cannot use the internet within that day if he couldn't buy a time on a serve...every students should only have 20hrs time usage per semester...our problem is every day their 20hrs is being reduced in 1hr.. the rule is the time per semester which is 20hrs that is given to the students was reduced 1hr only if he uses the internet..but our system is reducing their 1hr every day.

View 2 RepliesI'm having some very weird issues with interfaces right now.
I have a very simple setup. In one of my class, I have a Property implementing a Property from an Interface.
In my class it's like:

Public Property Form As IForm Implements IContainer.Form
Set(value As IForm)

I have like dozens of interfaces like this working throughout my project and I can't believe this simple one can't work!
