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]

View 1 RepliesI 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:
e.Graphics.DrawImage(printBitmap, .Margins.Left, .Margins.Top)
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

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?
View 3 Repliesi 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....

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].......

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.

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?
View 5 RepliesI 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.

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.

View 5 RepliesUsually I am a web developer so this is probably a very novice question. I recently made an app in VB2008, but I developed it in a huge reso (1920x1200).

I didn't really think about it at all while I was making the program.
View 1 RepliesHow to make my forms resize automatically. here's the situation. I have my intro screen, which a user may want to maximise. Once this is maximised, the whole program should stay maximised. Again, if the user chooses to restore the window to its default size, the whole program should remain in that default size. However, once the user clicks the button "Press here to start" on the intro screen, the form automatically reverts to its original size if it was maximised. I also need to be able to stretch the contents in the correct ratios to fit the new screen size.

View 1 RepliesLets say I want to create an array with 20 elements all set to a default value (let's say, 0)
But later, during runtime, I might want to resize the array. I might make it larger, to support 30 elements. The 10 new elements will have the default value of 0.
Or I might want to make my array smaller, to just 5. So I delete the complete the existence of the last 15 elements of the array.

My full screen sized Form is locked in size when I reduce it in size by clicking on the "restore down" [ie] not to the minimized size. I mean "locked in size" by I cannot for instance "grab" it on a corner and to increase or decrease its size. I suspect the control is in the properties window but I cannot find it.

View 5 RepliesMy form keeps resizing after debugging. FormBorderStyle is FixedSingle and AutoScaleMode is None...what am I missing?
View 2 Replieswe all know how to dock or anchor controls so that they resize themselves accordingly when a form is resized. It works fine till we have rows of controls on left and right size of the form. But what if have three columns (Columns as in visual sense. I'm not talking about any column control containing other controls) of controls? For example a form having a bunch of controls in the left side, a bunch in the middle and a bunch in the right. There may be a few more bunches in the middle. Now while resizing the form, I want the controls to resize accordingly as well as change their positions to make space for the previous bunch of controls that are resizing.
I mean, while the user increases the form size horizontally, the controls of the second bunch should resize and at the same time they should move right because the controls of the first bunch are increasing horizontally too. When the user decreases the form size horizontally the same thing should occur in the reverse order. I can manage it somehow using nested split-containers but that's too cumbersome. I would like to know if there's some better way to achieve it, like setting some property etc.?
Currently, my application is comprised of:a Main Form On this Form, lies an array of User controls, (pardon my terminology, i believe the more proper VB.Net term is Collection of controls). Within these controls are pictureboxes that have distinct graphics drawn on them. When I run this program, no graphics are drawn in the pictureboxes or it appears the graphics are overwritten. Also, it seems that the Form resizes uncontrollably varying in size on the screen and hits an infinite loop. I use the Form_Resize function for updating the size of the form. What could be causing this problem. What is the Paint method used for?Currently, to draw graphics on the Pictureboxes i am using the graphics object. I have two pictureboxes within the usercontrol for toggling back and forth for a more fluid refresh upon property updates.
From my reading, vb.net does not allow the ability to create an array of controls on a form, so I attempted to create an array of controls dynamically to try and stay as close to my vb6 application as possible because my knowledge is limited. This works, from what i can tell I know that in the Upgrade wizard the VB6.Compatiblity reference was used to try and mimic an array of controls, but I wanted to steer away from that and program strictly using VB.Net commands.
I want to prevent from resize of form. I set false MaximizeBox and I set FormBorderStyle to FixedSingle. I couldn't change the MaximumSize of form at runtime. If the user double click on the Tiltebar of the form the form resized. I couldn't prevent that
Then I write the following code at size changed event
If FormLoaded Then
Me.MaximizeBox = True
Me.WindowState = FormWindowState.Maximized
Me.StartPosition = FormStartPosition.WindowsDefaultLocation
Me.Size = InitialSize
Me.MaximizeBox = False
End If
Has anyone ever had or dealt with resizing issues on MDI Child forms? I am working on a VB.Net Windows applciation project I inherited from another devloper. When I took it over the forms had already been designed. There are one MDI Parent Form and two MDI Child Forms. When the application starts up the parent form and one child form open by default. Both the parent form and the child form will maximize, restore, and minimize. Although I have to move the parent form slightly, when it is not maximized I can resize it with the mouse pointer as expected. The child form will not resize and when I move the cursor to the border of the child form I do not even get the mouse pointer. Also, when both the parent and child form are maximized the vertical scrollbar on the child form is no longer displayed.
One potential problem is that there are lots of controls on the child form, which are inside several group boxes. When I comment out the controls, the blank form displays without the vertical scrollbar but will resize with the mouse pointer as expected. When I uncomment the controls the resizing does not work any more. The AutoSize propery on all of the controls is set to True. I tried commenting out the code setting the Autosize property to True on the group boxes only. The result of that is that the resizing still does not work and I lose the vertical scrollbar.I am trying to avoid having to redesign the form completely, however I am running out of alternatives. The project will not pass UAT if the resizing does not work.
I am writing a relatively simple "yahtzee" program. Its set up so that the user can pull up a options window and select whether they want the game to be 1 or 2 players. If the user selects 2 players id like the second players score card to become visible on the Score Card window (easy enough with the visible property) and i would like the Score Card form itself to resize it self (at run time) to allow the second players score card to fit. How do i make the form resize to fit 2 players at run time?
