I am trying to print an image (from file) to a the printer using a PrintDocument.I am re-sizing my image so that it is scaled to be full page on the printout when I print this the image is cropped slightly.
EDIT 2:I am using the margins to calculate the area to use:
With printSettings.DefaultPageSettings
Dim areaWidth As Single = .Bounds.Width - .Margins.Left - .Margins.Right
Dim areaHeight As Single = .Bounds.Height - .Margins.Top - .Margins.Bottom
End With
The bounds of the page are 1169x827 (A4) and with the margins it is 1137x795.After resize my image size is 1092x682 and I am using the following code to draw it:
The annoying thing is that when I print to the PrintPreviewDialog it is scaled perfectly but when I print the exact same code to the actual printer it does not fit.
EDIT 3:Full code can be found at this url Usage:
Dim clsPrint As New clsPrinting
With clsPrint
.Landscape = True
I'm using Report Viewer(VS 2008) to make a report in VB.net. I add Table with Table Header, Table Detail, and Table Footer. Then insert a Table Group(table1_group1) and add expression =IntRowNumber Nothing-1/10 on that group. I check page breaks at end.
But when I click Print Layout Icon its show an extra page(page 3): page 1 : page header+ table header + table detail(10 list data) + page footer page 2 : page header+ table header + table detail(5 list data) + page footer page 3 : page header + table footer + page footer ( this is the error)
I also try to print the report and its print 3 page.
I am having a problem, my Printpreview is showing 2 pages, but only printing ONE.. Here is the code... PLEASE HELP.

First off I'm using the Extended Webbrowser control from: [URL]
I use the Webbrowser control to access an ESRI web based mapping solution. When the ESRI map is loaded into an IE browser and the browser is resized then the map control resizing accordingly. When my Webbrowser control is resized the map webpage is not resizing properly.
I don't even know where to start with this problem. Is there some event that's not firing in the website? I can't simply refresh the whole website because the user may have panned and zoomed around. I want to just tell the website that the container control (Webbrowser control) is resizing now.

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.I need someway of taking the newly resized image and placing it back into the pbCrop picturebox, indicated by the "'code to draw it into the pbCrop picturebox" code below: NOTE (Ly = 60)[code]
How do I add constraints to image resizing code? I want the image to be no larger then 165x146. The below code does not hold the constraint when image is 525x610.[code]
1. Image Resizing: The code takes the screen when you press the button and then save the image. My question is, how can I set the image size before saving?[code]
2. Location (in the center):Almost all computer have different resolution from another computer. My question is how do I find the center of the screen and is where the program (when they open the program and see it in the middle of the screen)
Imagine I have a rectangle say 400px x 300px. All of this is very easy using Sytem.Drawing. DrawImage. But then I want to leave the left hand side as 300px but change the right hand side to 250 px. I can draw the box using 4 DrawLines but I don't know how to squash the image into the new shape. I want the right hand side of the shape to be 250, the left size 300 and the top and bottom 400px.I can't use DrawImage as it expects the left and right sizes to be the same. Is there a way to manipulate the image into the new shape?I've looked at other questions, but they only apply where the left and right hand side is equal.Any thoughts on how to squash an image into a shape which did not have parallel sides?
i was searching google for some kind solution and i found one, i tried to implement it in my code but it doesn't work. The problem is that after resizing white images they gets gray border.Here is the link of soloution i found:It says:
This problem is occuring because you are interpolating your image data to a new size, but along the edges there are no pixels to interpolate and .NET uses black pixels for these edges by default. To fix this you need to use an ImageAttributes class in your DrawImage call....
https:[url].....
CODE 1: And this is my code WITH IMPLEMENTATION OF ImageAttributes:
Private Shared Function ResizeImageFile(ByVal imageFile As Byte(), ByVal targetSize As Integer) As Byte()
Using oldImage As System.Drawing.Image = System.Drawing.Image.FromStream(New MemoryStream(imageFile))
Dim newSize As Size = CalculateDimensions(oldImage.Size, targetSize)[code].......
Code that opens image file this code works properly Private Sub MenuItem4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles FromFile.Click PBDisplay.Visible = False If OpenFileDialog1.ShowDialog() = DialogResult.OK Then PBDisplay.SizeMode = PictureBoxSizeMode.AutoSize [Code] ......
This code is what I am using to save image after it is re sized, It will not save the new image, it saves the old image and the old size. I am using a picture box to import the image into, then I am resizing the picture box and the image. But when it is saved it reverts to the original image. Private Sub MenuItem6_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Save.Click If SaveFileDialog1.ShowDialog = DialogResult.OK Then PBDisplay.Image.Save(SaveFileDialog1.FileName) End If End Sub
Ok, it seems my question might not have been straightforward, so here is a more generic question.On a form in a picturebox if I have a 32 x 32 picture. How can I scale it to be 64 x 64.I am not refering to stretching the image or resizing the picturebox. I mean using the ScaleTransform method of the graphics class. How can I do this without deforming the image?
I want to resize the resolution of an image before uploading it to local storage. Right now it saves the image in its full resolution and I have to manually resize it using width="200" height="200" or a css tag in aspx. I want to reduce the file size of an image before storing it, hence by resizing the image resolution when the user uploads it via button. I've tried using System.Drawing before and setting the int imageHeight and int maxWidth to be resized but couldn't seem to get it to work.
My code so far is: Protected Sub btn_SavePic_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btn_SavePic.Click Dim newFileName As String Dim SqlString As String [Code] .....
I don't have code because I don't know if its possible. I need to make a webbrowser for work that will auto rezie images like internet explore does when it is to big for the browswer, I have done it with vb6 b4 by parsing it into ram and then displaying the image, but I don't know how to do it in vb.net cause the code will not convert. Also I need to have vb.net auto send user name and password to the website its navigating to. The website uses a standard username and prompt window that pops up once you navigate to the web address.
I am trying to use itextsharp to take dynamic information and generate a PDF with it.. The PDF's use a background Image on each page which is different and the text content is positioned where it needs to be using the contentByte helper. Thats the plan anyways. I hit a hang up when I tried to add another page and then drop the image and text onto that page... My first page ends up with the image that should be on my second page and the first page image fails to display at all on either page... My code so far is as follows:
Function ID_and_Parking(ByVal id As Integer) As ActionResult Dim _reg_info As reg_info = db.reg_info.Single(Function(r) r.id = id) Dim _conf_info As conf_info = db.conf_info.Single
Imagine a have a painting program with a PictureBox, which I can paint on.I would like to have the ability to press "Next Page", and the program shall store my current image/page as "Page#" (where # is the number), and create a new one, which I can draw on. I should then be able to click "Previous Page", and get my previous image/page (in this case, "Page1"), and be able to edit/view that.So I have a PictureBox which is the "viewer", and then I have a lot of images, which are the pages.The way I would do it, is that I would store them locally as files, and call them "Page1", "Page2" and etc. in a folder.But I would assume, that this will require a bit processing power, and slow down the program - it will also cause problems, if for example "Page3" would be deleted - then the current "Page4" should be renamed to "Page3" and etc and etc.[code]
I have the code of a web page and it contains lots of "divs" with backgroud images like this:style="BACKGROUND-IMAGE: url(/images/image1.jpg)"Is there an easy way in VB.NET to get all the URLs from bg images from the page?

I'm working on a simple image tagging and searching app. I've got my images uploading to the DB, the tags being applied, but am failing when I pull them back - the images don't render. I found this here on SO, but I'm not able to get it working.
I am newbie here and sorry if I post at wrong section if I did it. May I know how to do that in vb.net? I try response.addheader but it seems this can only work but cannot save the image file to my document.
What I'm trying to do is grab a specific image from the page and throw it into a picturebox on my form. This isn't difficult and I know how to do it except this time in the source of the page there is no image url yet on the page if i right click copy source on the image there is a full link to it. I am confused and not sure how I could grab that image from the 'front' of the site rather than the 'back'.
I am placing and image using this [code]It works perfectly however when my document is extended to second or third page.. it does not stays on the first page.. it stays on same position however moves to the last page
