I hoping to find a current and simple way to do this. I'm using VWD Express 2008 and SQL Express 2008.I'm able to get the client's path to the image file using an asp:FileUpload control on the web form.
How do I upload the client's image file and display it in the web form's image control?How do I save it to the sqlserver? The image table is already set up with a "Image" data type column. Can the image be saved to the database as simply as other data types?

Does anyone know if it is possible to resize an imagelist/listview image without repopulating the image list? I am using scroll bar to change the image size from 25 point to 256 point. When I leave the scroll bar the imagelist repopulates from the files list. This can be very slow when working with high resolution pictures. I don't want to limit the image size to 2 sizes by using large and small imagelist.

I tried searching and found out that someone has written a multipart form uploader. Though it had one thing wrong: It transfered all the - supposedly - POST values in the url.. Which the web application doesn't like - somehow.

I created a new ShellAppBar window (similar to the taskbar) but i want it to replace the taskbar. My question is: i can remove the taskbar but can't resize the desktop's working area, so my appbar is sitting above the taskbar (which is not even there).

I would like for a user to upload an image to a file in my web application. However, before being saved I want to resize the image to a specified size. I have found code on the Internet to do what I want but I am having trouble adapting to meet my needs. Here is the part I am having trouble with:
' Resize Image Before Uploading to DataBase
Dim imageToBeResized As System.Drawing.Image = System.Drawing.Image.FromStream(FileUpload1.PostedFile.InputStream)
[Code]....
Rather than upload to a database I want to save the image to a folder in my web application. The problem I have encountered is that VB won't let me save a byte() to a folder. Not sure what I can safely change to adapt for my purposes. Why does it need to be changed to a byte() in the first place?

I have an app that displays images (using picturebox component). what I am trying to do now is to try to allow the user to resize the image how he wants it (scale). for this i think I need to create an instanece (bmp) clone of the selected image in the picturebox and draw it ontop of the original picture; then specifi new set of size points.I was trying to use the code below:
Graphics.FromImage(PictureBox1.Image).BeginContainer('i do not know what to do here')
I need to specifi the new size of the graphics container but I do not seem to have any clue on how to do it.

I wrote a piece of code that grabs a fileupload, puts it into a memory stream, converts the main pic, and thumbnail pic, then saves them as jpegs, then updates the database.
Everything works fine, except one little glitch. If the DPI is above 300 then the image doesn't save right. It get's pixelated and blury.
here is the code.
Dim fileLen As Integer
# Dim myStream As System.IO.Stream
# Dim ImgContentType As String

I am new with visual basic 2008 express edition. I wanted to ask on how to resize an image in a picturebox with a set height and width.[code]...
All it does is open a file with open dialog filters. I have a set height and width for the picturebox. If i open a picture with a height and width greater than that of the picturebox, the picture box will only display a portion of the picture.

I have a form where i load an image to a picturebox. I open a dialog to prompt the user to grab a file and once that is done i pull the image into a picturebox. Now i want to resize all incoming images but.... because of how it affects my ability to draw lines in the picturebox i am restricted to leaving the picturebox size mode set to normal. So i set out to write a resizing function.
The issue i am having is that eventhough i pass the function an image. I get the Height and with from the image object and it appears that i should be tripping some of my IF/Then statements ... neither Scl or Scl2 ever gets set which in turn keeps nw_height and nw_width from setting themselves properly.
All 4 of those variables stay 0 at all times and im not sure why.

I have this fingerprint scanner I'm working with. The fingerprints taken are index/stored in our imaging system and the fingerprints are put on certain documents and printed.When I scan the image in and then load it into a bitmap object, the width and height are (w:480,h:640).Now if I open this file in any image viewer and print it from there the finger print is as big as a fingerprint should be.Now when working with it in code, it's huge. I have found some resize code online, but the resulting image is horrible.Is there anyway to resize an image while taking in account the dpi and such so the image is highest quality (same as print out?).
