Dim image__1 = System.Drawing.Image.FromStream(fromStream)

I have the following code to generate combinations of string for a small list and would like to adapt this for a large list of over 300 string words.Can anyone suggest how to alter this code or to use a different method

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.
View 1 Replieshow to resize images?
View 6 RepliesI 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

View 1 RepliesI 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 am trying to figure out how to go about my two problems i am currently having when trying to display a resized picture into a picturebox on my form.
What does it need to be in order to grab the image thats already been cropped in the pbCrop picturebox? I have the cropped image in the pbCrop picturebox and i then am trying to resize it.[code]...
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 an application developed in VB 6.0 and VBA that uses latest Office 32 bit version. But since this application is 32 bit, it does not run on systems where 64 bit Office versions are installed. What is the best strategy I have to adopt to port this application to 64 bit. We have a mandate to use VB.NET and minimal (as much as possible) code modification from VB/VBA to .NET 64 bit. Please suggest the best option I can use so that I can leverage all best practices for this porting.
View 2 RepliesI 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?).
View 2 RepliesI've got code to allow the user to import an image to the document they have opened, however right now, the image displays at it's default size, and well, if it's a large image, the document stretches and looks like crap. I want the user to be able to select the image after they insert it, and have the handles show up on the corners so they can resize it, and would also like to have it allow them to move it around the document if possible.

View 4 RepliesI'm currently in the process of making a dynamic signature generator, and I want to make the user be able to see what he would get... So I thought of putting a browse button and allowing them to load up a background image for their signature, but I also want the picturebox to resize according to that image's size. I need them to be the same size because of the image's X, Y are needed for the signature.
So I'm using this code for that:
LocalMousePosition = PictureBox1.PointToClient(Cursor.Position)
xy.Text = ("X=" & LocalMousePosition.X & "," & "Y= " & LocalMousePosition.Y)
It works fine, but it only gets the coordinates for the picturebox, not the actuall image, so I think if the picturebox is the same size as the picturebox it would get them just fine..

The image is bigger thant the picturebox, how can I resize the image to fit the picturebox?
For the resize I have a form to reduce and expend image code:
Dim source As New Bitmap(Form1.PictureBox1.Image)
Dim target As New Bitmap(Size.Width, Size.Height, PixelFormat.Format32bppRgb)
Using graphics As Graphics = graphics.FromImage(target)
graphics.DrawImage(source, New Size(16, 16))
End Using
As far as I know it resizes but when I save I get the default icon image instead of whats in the picture box?
