What I've done so far.My server interface only accepts POST requests, that's why I'm using POST and asked if something is wrong with the way I use the parameters.

Currently my ListView sorts items by image.index. So 0 is at the top, then 1, 2 and so on. Think of it as an IRC chat room nick list. Ops at top then the rest are sorted alphabetically

I'm writing a Cleint/Host program that sends a image over tcp (from printscreen, not a file) to the host. Everything seems to work fine and the image is transmitted and displayed in a picturebox plus saved to a folder. The problem is when the printscreen is bigger than 176040 B. First the limit was 128000B but after setting the sendbuffersize and recivebuffersize to 1000kb the limit is 176040 B. Could it be a limit in the tcp protocol?
Here's the client code

View 3 RepliesI have 6 picture boxes 5 of which shows the players and 1 picture box for the basketball. What I would like to do is to drag those picture boxes on the court at run time but when I drag them inside the court the images should not be moved instead they should only be copy inside the court. how do I do it? Im having a hard time solving this problem. what I have right now is that when I drag the images the image are moved to the court and not copied. Also after dragging the first picture box that picture box from the source should be hidden then the 2nd picture box will now be visible and so on...

I have an application that downloads a .jpg snapshot from an IP camera, writes it to the server hard drive, attaches it to an email and sends it out to my users. Pretty simple until one guy had to mount his camera upside down and that's how he received the image via email.
It gets a bit annoying after a while, so he asked me if I could rotate it 180 degrees before attaching it to the email. I have absolutely no idea - hence my post. The app is on a hosted ASP.Net v3.5 web server.

My current code looks like this:

e.Graphics.DrawImage(New Bitmap(ds.Tables("Track1").Rows(0).Item(1)), 3, 3)
End Sub
When I run my program I get the following message in my code: Illegal characters in path how I can draw the image from the database?

I am trying to verify that an image has been loaded into the picturebox1. I am loading the image from the web and need to verify it has arrived before I can save it to disk. If I save it to soon I will save nothing and that will crash the app. I have tried to use 'if PictureBox1.image = nothing then' ... 'End If', but that isn't a valid check. I can obviously not check picturebox1.image if it is empty or has an image.
So the question is, how do I verify that the file has finished loading?
I am trying to incorporate in my vbdotnet application a form in which I would like to make a thumbnail from an image. So what I have is two picture boxes, one with the source image and the other with the destination image, I would like to crop the image from picture box 1 and display it on picture box 2, but the way I wan to crop it is not giving the coordinates of the selected area box but to simulate a selection area box in which the mouse can move the box and select the area of the picture to be cropped. This selection area box would give me the coordinates i need in order to proceed the cropping. The problem is I don't know how to create this selection area box. It is like doing the cropping on a graphic design software like Macromedia Fireworks, Adobe photoshop, even paint.

View 3 RepliesI vagely understand how to edit an image using Graphics. I can rescale an image using scaletransform but I want to be able to use a dynamic scale i.e., given an image with (x,y) coordinates, I want x_new = x_old + y*Factor so that when the image is stretched one end is stretched more than another.
View 6 RepliesI would like to create a pixel viwer (i.e. zoom into a picture to view the image's pixel information - Similar to windows paint or Photoshop). I have created an image zooming code, but it enlarges the image and sadly, doesn't show the blocks of pixels I was hoping for.I have thought of several ideas, but each worse than the next. As an example, re-create the image, increasing each pixel's area based on the zoom-level. But I can tell already that this process would be slow and judging by photoshop (or paint) there is a quicker method.
