I'd like to make a simple VB utility to resize images using vb.net. I am having trouble figuring out what vb class to use to actually manipulate the images. The Image class and the Bitmap class don't work.

View 5 RepliesI need to know how to make the web application crop an image and resize it as a thumbnail to use it later on in the application?
View 3 RepliesI'm using a web cam that takes 320 X 240 pictures. This sort of gives the picture a "landscape" look to them, and I need to re-size the pictures to a 169 X 225 "portrait" picture. Its for a badge program. Anyway, when I re-size the pictures, they get all scrunched up because of the difference in aspect ratio. Is there a way to re-size the image and the aspect ratio at the same time? Would this be considered cropping or resizing? I'm a little confused on where to begin. I mainly use VB, but if someone has a good example in C#, ill take the time to convert it.
View 3 RepliesI had a project which will have a function to resize the images in the picturebox..i've seen some code snippet in resizing the images. The code works fine but it automatically resizes the image when i run the program..what i need is that the user will be the one who will resize the pictures..does anyone knows how to do this? i'm using vb 2008.
View 8 RepliesI'm using VS 2010 and MySQL 5.5. I've got a data grid view displaying the results of queries entered by the user, shown below. It works; the trouble is that if there's an image in the results, you'll only see a cell-sized very long thin strip of it.
So I want to a) resize any images to a reasonable thumbnail height (say, 100 pixels, naturally maintaining aspect ratio) when displaying them, and b) resize the row to fit them.[code]...
I have a Form1 where i can add usercontrols during runtime. I draw their appereance in the OnPaint event using the GDI+ engine. The greate part is that i want to be able to resize these images during runtime wich goes pretty well now cause i draw points in percentage of the control. Unfortunetly it is very difficult to draw nice images/drawings ect with the GDI+ engine. Is there any other way in doing this?

I simply want to have a list of all graphics saved in specified folder displayed as miniatures - this suppose to be a sort of an image browser - it does not have to be done using ListView, so I'm open to any suggestions.
I have a program in C++, that is doing some calculations. I use a vector in C++ and resize the vector in the program, in order to conserve and allocate memory. Can you allocate memory in vb.net? So if my user inputs 1000, I want an array/vector to have a size of 1000. Can I change the size of the vector in the program? And is there a difference between container types in vb.net, I was just assuming
Dim xx(1 to 1000) as double, is the standard way of declaring.
And resize xx(1 to N) would be the way to resize.
I am using visual studio 2008 express.

I created so many listviews in my project, that im too lazy to add to each listview a resize event with percentages. Is there any other trick, who just scales the columns so as they are?
View 3 RepliesI'm starting work updating an UI for one of my company's applications and I'm running into a sticky issue. The parent control contains several panels, each of which can be turned on or off depending on user input.
The final panel in the user control contains another user control which gets resizes according to a toggle switch. Essentially, it "opens" up more information.
While the child control (ChildControl) is docked to Fill inside the parent control (ParentControl), when I add height to ChildControl I can't get ParentControl's height to get updated as well. Currently I'm handling the ChildControl.Layout event in ParentControl but I can't seem to reach that code. To resize ChildControl, I'm calling Me.Height += 200 in ChildControl.vb.
I have a number of image files name image1.gif image2.gif image3.gif etc upto image52.gif

if 2 is generated image2.gif. However I have 52 such images to be displayed in 16 picture boxes so I was wondering
if there is a more efficient way than a select case method for each image and each picture box.

I have written an application in which, among other things, there is a picture browser, allowing the user to load and look at pictures (jpeg-type). So I thought it would be nice if they could print their nice pictures too. And here is where all my problems started. I've tried almost all the code examples given to me, but none works. Isn't that strange?
I want:
a) The user will click the print button and the print dialogue will appear and thus enable him or her to choose wich printer to use
b) When the choice is made, click OK or PRINT or WHATEVER and the picture/photo will appear on a piece of paper which they can frame and hang on the wall or where ever
Yes I'm sounding sarcastic, and that is because I'm tired from lack of sleep, trying to make this happen. And I only have a few days to complete everything. To make it worse I haven't even started on the part where they are able to print text from textboxes on a form... Oh My God. for some reason I though printing something from an application would be the easy task when it comes to programming in VB. I was obviously wrong. It happens from time to time.
How to retrieve the 10 images from a particular folder in vb.net
View 1 RepliesI'm in the middle of making a program launcher. I've been able to make a version of it before, but now I want to add more options for viewing the shortcuts. The 2 main views I'm trying to get are: Icon only and Icon with the name.
Here is my original code for only the name:
VB.NET

'Start bottom right of screen

SystemInformation.WorkingArea

I have switched over to a listview because I assume that's what i will need in order to show images. So I guess my first question will be how do I get only the icon from each file and then show it in the listview.

I am making a program that takes pictures of the webbrowser control on a set timer and save them in a picturebox.. I then use backgroundworkers to check the images against others stored in the program. My issue is, the backgroundworkers do not properly check the images against the ones I have stored in the program.Could this be because the images and picturebox are stored on the main thread, and no in a background worker?In other words, I am taking picture from my webbrowser and putting them in my picturebox. Then, I am comparing them with images already in the images. The only problem is, the workers are unable to properly compare the images.
