Generates Gradient Colours On A Form?
Jan 1, 2009
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.

Public Class Form1
Dim x As Integer, y As Integer
Dim img As Bitmap
Dim pixelColor As Color
Public Function getpixel(ByVal x As Integer, ByVal y As Integer) As Color End Function Private Sub find_img_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles find_img.Click
[Code]...
whenever i load the image, i have to load it a second time to get the colour, or if i load a new one, i get the colour from the previous image, any ideas as to why?

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
[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 ?

I have a form which I am adding a gradient to. However on this form I have aTableLayoutPanel (with controls) with the dock set to Fill. When it fills it covers up the form and the gradient on the form. Is it possible to make the TableLayout Panel and its controls colour clear or can you pass the same gradient color from the form to all the controls in the TableLAyout Panel (including the TableLAyoutPanel).

I am using a MDI form and child forms. Now I don't like the standard back colour of mdi form so I got code on the net which paints a gradient colour to the mdi. So far it is working okay.Now the problem is when I load a child form or close it or do a similar activity then it causes flicker in the mdi background. This gets pretty annoying at times and you see the background flicker.

I have recently moved from developing in vb.NET 2008 to vb.NET 2010. There is a form in the application that uses an old Ascend Gradient Caption control to visually separate sections of the form. These controls are located on a tab control. The problem isthat the gradient captions seem to be unstable. They appear in odd locations on the tab pages at runtime, and I can't seem to select them in the designer. I can choose them from the combo box on the property page and edit the properties, but they stillbehave erratically. I understand that these are older controls and was wondering if anyone has had this problem and/or could recommend an alternative control

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 text box where I write different frames from a serial port.
I'd like to write those frames in two different colours but I don't know how to do it.
If I change the option Textbox.Forecolor, it changes the colour of every single line, and that's not what I am trying...

With my program I have made a settings form - changing the colour of other forms- and instead of writing the code for each individual form I was thinking if I can create an automatic system. The forms have different types of names & the items within have different names.In the setting form i have 3 color dialogs (one for background,Text colour -labels-, and a button color -forecolor-)
Code for Formsettings
Public Background As Color
Public TextForecolour As Color
Public buttontext As Color[code]......

I've found out how to change colours for the text editor, etc, but is there any way to change the colours in the help? It'd be nice to be able to have [for example] white text on a black background. It'd be easier on the eyes for lengthy reading sessions.No crops were circled, or animals mutilated in the making of this sig.

I'm a beginner to VB2010. If I draw a red line on a BLANK form, obviously its red. But if I draw a second red line, which crosses the first, is there a way of controlling the colour at the crossover position, for example returning it to the original colour of the form?

I'm trying to make it so my textbox is colour-coordinated automatically. By this, I mean that if a line begins with a certain bit of text (for example, a line starting with <text>) then it will make the whole line red.I realise that this may not be possible with a standard textbox, so I don't mind any suggestions that need an RTF item.

Can I create a Pen dashpattern that consists of alternating colours rather than a solid colour followed by a space? For example:
LinePen.DashPattern = New Single() {6, 4}
creates a pattern with a dash of 6 pixels followed by a space of 4 pixels. Rather than a space, I would like a different solid colour. That way I could create a rectangular cursor with something like a black/white alternating pattern, which would be clearly visible on top of any picture.

I am working in vb.net, visual studio 2010.
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.

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
