Enlarge Image To Normal Size In ASP.NET 2.0?
Mar 10, 2009
My users uploads a picture and the picture get saved into my SQl Server Database.My users view the picture on the page in a normal Image WebControl with size 150px by 150px - example can be found[url]...
If the user uploads a picture of 300px by 200px the image will look funny in my static 150px by 150px Image box. Any idea how i can display the Image so it wont be fuzzy?
Also, how can a have some form of pop-up that will appear on the screen, showing the actual size of the picture from the database when the user clicks on the 150px by 150px Image.
Note: I dont want the Image static size to increase as this will totally mess up my page layout and look. It must be some form of pop-up or something. Something i have seen before i think was really cool. User clicked on the small image and then a pop-up appeared in the middle of the screen with the actual size of the picure and everything ells on the page was disabled until the user clicked on the close button.

when I click the Open button a file is opened and its items are sorted alphabetically. to do this I have doubled the size of my list. However, when I click the button again to reopen the same file, the items will ADD ON to the previous open-file event even though I have this piece of lstListboxTwo.Items.Clear()(the correct thing is to clear the previous items and add the new ones)So I think this has to do with the new size of my list..I think that I have to set the list size back to its normal size when re-clicking on the button.

Dim List() As String = {""}
Dim count As Integer

I want to design visual match the pairs. There will be two columns. The left column will have images and the right one will have word labels. User have to drag image over the correct label.
Since the form size is small, images will have to be smaller (thumbnails). So there should also be image enlargement when user hovers mouse over the image. The user should also still be able to do a basic drag-and-drop of the image.

I want to enlarge an image, possibly up to 32 times or 64 times bigger than original dimensions (so that the user can see each pixel) if possible. The following is a simple function that I have to enlarge an image.
Private Function xEnlarge(ByVal Source As Image, ByVal Rate As Double, Optional ByVal Quality As Drawing2D.InterpolationMode = Drawing2D.InterpolationMode.HighQualityBicubic) As Image

I have just found that if a DataGridView image column's size (height & width - in pixels) is smaller than the image's original size (in my case all images are exactly 180 x 180 pixels) at the time the cell is populated then the image is automatically being converted to a lower resolution I assume to fit the image completely within the size of the cell). How can I stop the automatic scaling of the image?
The image below show the same file displayed twice, both at 60x60 pixels ('Thumbnail' column) and a blowup of the image (PictureBox populated via the CellMouseEnter event) to it's right. You'll notice the resolution of the first blowup is far less the the second. so, what made the difference in the resolution of the blowups is? In the second blowup's case I'd first stretched the image column's width to ~180 pixels and set the row height to match (via the ColumnWidthChanged event) then populated the DataGridView then stretched the image column to 60 pixels (its minimum).

I have a form which contains an Image control. What I am trying to do is find a way to adjust an image according to the size of the control and have the image look normal no matter how I adjust the Image control. I want the actual image to fill the Image control completely and not loose any integrity.

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

Is it possible to take the last row added to the grid and enlarge it for viewing? Then when another row is added it enlarges and the previous goes back to normal size. When I say enlarge, almost like a magnify effect. Am I making sense?

I have a picturebox with a tiled background image (plane white bitmap), and an "image" resource centered in the middle of it, I would like to chance the size of this centered image within the picturebox.
I tried:
picScaledRepresentation.SizeMode = PictureBoxSizeMode.CenterImage
picScaledRepresentation.Size = New Size(Width, Height)
But this just changed the the size of the whole picturebox, rather than the image within it.

I'm currently working on a school project. And a part of the program is to 'change' the images. All images added are BMP-files. But the output has to be JPEG. Now there are 2 other problems:
- The width of the image should be between (70-165 ) Pixel and the height between (65-185 )Pixel
- The filesize of the image should be between (3-4 KB)
I know how to change the width/height, but it's hard to make the filesize between 3-4 KB.

I was wondering how can I change the text of a Radio Button with the help of Check Box...Let's say the text inside the Radio Buttons starts in size 10, Not Bolded or Underlined and in Black.
I have 4 Check Boxes and each of them does something to the Radio Buttons. One of them should make the font Bold, another Underline it... Change color,and Enlarge font. What codes should I use for that?

I can not seem to figure out how to change the size of a photo being put into a picture box.I need the photos that are placed in the picture box to come in their original size....I have 4 different pictures in an ImageList and depending on what a Text box from a different form says, one of the photos will be displayed in a picturebox when the form is loaded. Right now all the images show up very blurry and in the predetermined size in the imagelist. Here is my code:[code...]
As you can see I figured out how to autosize the PictureBox (candypic) to the size of the image coming in....just cant get the image to come in as the right size.....
When I created the imagelist all the photos have a default size of 16, 16 when entered into the list.....I see in the imagelist properties how to adjust the image size but it groups them together as one.
