I've got all the code figured out to make a picture box appear with a gradient inside of it. My problem is that the gradient doesn't appear in the picture box when the form loads, paints, or when the picture box is painted. I can only make the gradient appear if i click the picture box after the form appears.
Dim xFormTopColour As Color = Color.Black
Dim xFormBottomColour As Color = Color.DarkOrchid
Private Sub frmTestGradientBars3_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Call GradientPictureBox(xFormTopColour, xFormBottomColour, picSample)
In my project I am using a camera to capture images. The images will be stored in a byte array. Now I want to display my images in byte array to picture box on my form. I am pasting the code bit below.
HTML Declare Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory" (ByRef Destination As Byte, ByRef Source As Byte, ByVal Length As Integer) Delegate Sub MyFrameHookerDelegate(ByVal FrameType As Integer, ByVal row As Integer, ByVal Column As Integer, ByRef lpImageAttribute As TIMAGEATTACHDATA, ByRef Buffer As Byte) Public ImageBuf() As Byte [Code] ....
I want to display the image from ImageBuf() to a picture box on my form.
I have two pictureboxes with images in them inside a panel. The two pictureboxes have the background color transparent. One half of one of the picturebox is over the other and that half gets the panel backgroundcolor. How can I make the pictureboxes to not get that behavior.
I am using a PictureBox to display images. I have SizeMode set to StretchImage. While this does indeed show the whole image, it is of coure stretched. Is there a way to prepare the image to be displayed so it will fit correctly in the PictureBox? I just want it displayed without distortion and within the box.

I have used a single picture box and I want it to display many pictures when I run it, whereby I cant navigate through it by clicking next or back. I used some codes, they had no error but they weren't able to display my pictures during run time.

I've tried using the method in the link below, but unfortunately this only works with .exe files. I want to be able to display icons from all filetypes in picturebox's.

I'm constructing a Management system. Now, I have a problem with the interface design.
I wish to use ForumsAccount's tab control and JuggaloBrotha's gradient form in my application (both can be found in CodeBank).
But the problem is, I'm confused in the design ! Which one shall I use for the main form ? an MDI form or a normal form ?
Details about the Mgmt. System app: it will be used to manipulate everything for a small firm, like adding customers, employees, payments, etc.. Everything is managed using the app and saved to the db.
I have a PaintEventHandler connected to a picturebox via AddHandler.
In PaintEventHandler I have coded this for writing the drawing to PictureBox1.Image:
Dim PictureBox1 As PictureBox = CType(sender, PictureBox) PictureBox1.Image = New Bitmap(PictureBox1.Width, PictureBox1.Height) Dim bmp As Image = PictureBox1.Image Dim g As Graphics = Graphics.FromImage(bmp)
... drawing something ...
PictureBox1.Image = bmp
Everything works fine but after running through the paint event handler and showing the picture on the screen it calls the painthandler again and again. It does not stop.
Replacing the code above with
Dim g As Graphics = e.Graphics
Makes it running. But then I cant save the Image to a file.
So i want to apply gradient to a square, a center to edges gradient. This is the code:
Public Class Form1 Private Sub PicSourcefrm(ByVal sender As System.Object, ByVal e As PaintEventArgs) Handles Me.Paint Dim Graph As Graphics
[Code].....
NOTE: Picsource is just a PictureBox named that way. If I put "BrushSquare.SurroundColors = Color.Red" in a comment. The program works but the edges are white, not red like I want them to be.
I have this code for a gradient form(EXAMPLE 1). It works fine on its own.I tried putting it into an existing project of mine and I cannot get it to work. The project is quite large so I am no sure what the issue is. Is it due to the fact that I have an InitializeComponent() line in the my Sub New in Example 2? Note I have alot of code
EXAMPLE 1: Public Class Form1 Private Sub Form1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles Me.Paint 'Creating a new Rectangle as similar width and height of the base form

DataGridView, add unique gradient to each Row I like to add a gradient brush to each row of my datagridview. I like to change the gradient colors for each row independently depending of some cell values in the row. I know how to add a solid background color to each, cell, row, column etc. but I do not know how to add a gradient brush to each row individualy.
I need to fill the datagridview with values, the datagridview is disconnected from any database or other data source. After filling the datagridview, I want to step trough each row, find my key values, decide the gradient colors and then add the gradient to the row.I like to do something similar to what I now do with a background color:
For Each R As DataGridViewRow In DGV.Rows Dim CS As New DataGridViewCellStyle Select Case i

I am creating a page that auto-creates a pdf file from data in the database. I have the entire pdf working with the exception of the pdf background. The customer wants a gradient which I will need to repeat, but how would I create this? the image is 1px in width 976 in height [Code]. I was hoping that declaring a longer width it would stretch the image across but this failed.
I am using Visual Basic.NET 2008. I was earlier a VB 6 developer. I found a (VB 6) code online which generates gradient colours on a form. It has a small sub (routine) which does the trick. If we pass red, green and blue values then form's backcolour changes and it appears like a gradient.Now that code is not working in VB.NET.i mean is there an easier way to generate gradient colours in VB.NET (2008)convert the code I have into .net specific so form's backcolour becomes gradient.I have attached a zip file which contains the code.
How can I change a form's backcolor to gradient one. The code (VB.Net) - e.Graphics.FillRectangle(New Drawing.Drawing2D.LinearGradientBrush(New PointF(Me.Width, 0), New PointF(Me.Width, Me.Height), Color.FromArgb(0, 58, 140), Color.FromArgb(0, 215, 255)), New RectangleF(0, 0, Me.Width, Me.Height)) 'fade from left to right
This code changes the form's background to a gradient one. It works fine. Now I want this to take place in an MDI form which will be a container for other forms. If I turn option IsContainer = False then it works but otherwise it does now. How can I change backcolor of MDI Form to a gradient one ?
