I am loading an image on picturebox, then trying to paint some particular pixel but it does not work for the tif image that I have. I got the following error message "SetPixel is not supported for images with indexed pixel formats."
I am trying to resize images in batch using the below VB.NET code. The images are fairly large and when they are resized the images do not look very smooth. I have looked at Drawing2D.SmoothingMode.AntiAlias but cannot get that code to work.
Imports System Imports System.Data Imports System.Math

I want to create a new bmp file with 200 x 500: Append the footer.bmp into the bottom of the new image - position (0, 300) Resize the product.bmp to 200 x 300 and position into (0, 0)How do I do this using VB.NET?
Dim oBitmap As New Bitmap(200, 500)Dim oGraphics As Graphics oGraphics = Graphics.FromImage(oBitmap)
I'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've got a data-bound data grid view and one of the fields is an image. How do I scale down the image to a reasonable thumbnail size (say, 100px wide) and adjust the height and width of that cell so that it fits the image?
I am attempting to load all images from a directory to a FlowLayoutPanel. I am using the GetFiles() method to retrieve the files with a filter to just retrieve JPG files. When I run the program, it returns 'Conversion from string "*.jpg" to type 'Integer' is not valid.' exception. The offending line of code is:
For Each foundFile As String In My.Computer.FileSystem.GetFiles(FolderBrowserDialog1.SelectedPath, "*.jpg")
i trying to open a directory to list images in it..i tryed lots of codes but cant get it to work?last one was.
Public Shared Sub Main() Try ' Only get files that begin with the letter "c." Dim dirs As String() = Directory.GetFiles("C:\Users\TECHKER\Desktop\PROGRAMMING\PROJECTS\trainersTool\images\plyo", "*bmp")
im trying to open a directory to list the images in it i have this up to know
Dim strFileSize As String = "" Dim di As New IO.DirectoryInfo("C:UsersTECHKERPictures") Dim aryFi As IO.FileInfo() = di.GetFiles("*.*") Dim fi As IO.FileInfo
The code below displays a thumbnail of each image in a specific server directory and when I click on the image it pops up a nice full sized picture. It works perfectly.
I would however, like to be able to delete an image. I first thought I could have a button at the bottom of the page with a checkbox next to each image, giving it a uniqueID as per the filename but as they are dynamically created I couldn't figure how to handle the Click Event on the button for a randomly named Checkbox ID. Then I tried adding a button next to each item and then tried an OnClick & OnServerClick to call a Sub but this didn't work either.
Private Sub ImageList() If Directory.Exists(Server.MapPath("JobImages" & DBC_JOB_JobID.Text)) Then Dim MySB As New StringBuilder

Is there any way to make VB.NET to accept for all Date Formats as in VB6.0...I'm upgrading VB6.0 applications to VB.NET... Here I'm finding the Functionality difference due to VB.NET feature which goes for System date Settings.I tried using CultureInfo. But it also specifies only one format at a time..removing this functionality difference
Explanation : IsDate("MM/DD/YYYY") Returns False if the system date setting is of "DD/MM/YYYY"
although this topic has been posted for many times, I still can't figure out how to copy multi formats in clipboard.For example, I have a class called "Meta" and it contains data of a drawing. So if someone copy it to the clipboard, it should contains the original data of the class in a custom format called "drawing", a metafile of the drawing and a bitmap in case some app can't read metafiles. How exactly can I do?
I wish to avoid duplicate files using content based in any drive. Files may be at any formats . I dont know wat algorithm s used for fast search and how to compare all data formats.
I am completing a project for varsity and have done a lot of research on this topic but I can't seem to find the solution that I need. I am using Visual Studio 2005 and .NET Version 2.0. Here is the formatting they want me to use for the Cost Price textbox:"In your form, it should not be possible for a user to enter a cost price of 123.456 nor $123.45 (since we work in Rands and we also dont want to store the $ symbol nor do want the user to type a decimal point or a comma). Make sure that the cost price field has the following format: R ###. ## (where a user only has to enter the numbers)."
I am a little programmer in .net. I have a problem with opening flv files in my system. I want to make a software in .net which can open these files. If these files could be converted to wmv or any windows supported software I could open them & to be glad for new coding. Is this possible?
I would like to ask if you guys know how to convert 1 to 00001? For example, I have an item in my database with an ID of 00001. When I add another item again, it must increment already to 00002. But when I try adding one, the next ID saved is just 2. The zeros aren't on the left side.
The code is shown below da = New OleDbDataAdapter("select * from booklet", con) cb = New OleDbCommandBuilder dt = New DataTable
[Code].....
The output in the database after the 00025 is 26 up to 50 only. If I add another again, it's just another 51-75 only. I can't seem to save it on a format like the 1st series of ticket number that I've added directly on the database with the format of 00001-00025.
If mystringvar length is less than 10, it gets spaces padded as expected. If myStringvar length is greater than 10, it is still displayed in its entirety and results in everything after being pushed out of their proper place. Is there something in the formatting codes that I can include to ensure that only 10 characters would be displayed? I could write my own function for dealing with it, but I'd like to avoid as much custom coding as possible, ya know?
