I'm trying to turn this into a UserControl for a project and my end goal is to have a combobox that lists all of the colors in the color enum and it also shows a little box next to each item in the drop down that shows the color of each color's name. Just like the one in VS 2005 when you click Tools -> Options -> Fonts & Colors, there's an "Item Foreground" and "Item Background" that does this.I already have the drawing of the colors and whatnot done, here's the
Dim CurrColor As Color
For Each aColorName As String In System.Enum.GetNames(GetType(System.Drawing.KnownColor))
CurrColor = Color.FromName(aColorName)
I am trying to write code to load all nown color names from color.xxxxxxx in a ComboBox, but can not get it right. I can not find the Color Enum member. What I had in mind was something like this:
I have a question for a combobox in Visual Studio 2008 (VB)If illed a combobox from a table and the use the following statement: Me.cmbProduct.SelectedValue = 1 (or another number)The problem is now that in the form the value is selected but with a blue color. I have on my form several comboboxes but i don't want that blue color.
Well I'm trying to change the form color using a combo box. It seems easy, so I tried it. I just get errors. This is what i'm trying to do: Form1.BackColor = Color.Red But it fails and gives errors.
I have a combobox in a toolbar on my form. I want each item to have a specific forecolor. The forecolor property for the combobox only sets the forecolor for all items in the combobox. I though of overriding the drawitem event but sharpdevelop doesn't show a draw item event for a combobox embedded in a toolbar, only when i add a combobox to the form.
I have a Win Forms app written in vb.neIn it, I have a combo box with an OwnerDraw Item routineUsing this routine, I am able to implement an application-wide default value for a selection color like shown below:This works great except for one tidbit:ction color again in teh textbox portion of the control
I've created an ownerdraw ComboBox (used as DropDownList only) in Visual Basic .NET 2010. I inherited ComboBox and set DrawMode to OwnerDrawVariable. The control itself and the dropdown items are drawn with Paint and DrawItem.
The control works fine so far, but there is one thing i was unable to change: When i click on the combobox to open the dropdown area, this new area has a very bright border color (nearly white) which I want to change to black. I've uploaded an image of the current control and how I want it to look like:
I have a combo box which will store a list of RGB values generated when the user makes a custom color in the color dialog. The values are stored in the combo box in RRR, GGG, BBB format. I have this working. The code for this is as follows:
dlgChooser.ShowDialog() Dim colorR As String = dlgChooser.Color.R.ToString() Dim colorG As String = dlgChooser.Color.G.ToString() Dim colorB As String = dlgChooser.Color.B.ToString() lblTitle.ForeColor = dlgChooser.Color() cmbRecent.Items.Insert(0, colorR & ", " & colorG & ", " & colorB) cmbRecent.SelectedIndex = 0
The next part is to change each recent color's background color to match whatever color the values represent (so that it's easier to pick from the colors). How do I assign a background color to each item listed in the combo box?
I have added a custom Control to my project, but every time I edit it and rebuild the form that I use the custom control in adds the project name in front of the control and won't compile. i.e. Project name = MyProject, Custom Control name = MyControl. When I rebuild the project after editing my control I get an error, MyProject.MyControl doesn't exist. If I remove the MyProject from the line it compiles and runs fine until next time I edit the custom control.
I can't figure out what I would be doing wrong to cause this, or why it is putting the project name in front of the control, but then not accepting it. I am also struggling figuring out how to change the back color on an individual cell in an Datagridview Combo Box. The style.backcolor property of the cell doesn't seem to do anything.
I have a combobox called cbMaterialType on a windows form that's bound to a table in SQL - everything loads great and the combobox displays 'Material' items as it should, in that table I have two fields - Material (as mentioned above) which is a char(25) and InStock which is an nchar(1). If the InStock field contains a '1', I'd like the individual material to be green in the combobox, if '0', then red. I have the simple code in the drawitem event of the combobox as follows, but can't seem to get any results at all:
Private Sub cbMaterialType_DrawItem(ByVal sender As Object, ByVal e As System.Windows.Forms.DrawItemEventArgs) Handles cbMaterialType.DrawItem If MaterialTableAdapter1.GetData.Item(cbMaterialType.SelectedIndex).InStock = 1 Then cbMaterialType.ForeColor = System.Drawing.Color.Green Else cbMaterialType.ForeColor = System.Drawing.Color.Red End If End Sub
I've never worked with any form of color in comboboxes before and this is my first attempt at the drawitem event.
I created a tool that creates a kml file where several Scrambling codes ( SC are simply number) are shown on google earth and to each of SC is associated an automatic color:
For i = 0 To ListBox2.Items.Count - 1 Dim intR = oo.Next(0, 256) Dim intG = oo.Next(0, 256)
I have a requirement to have a button filled with a gradient colour (red to green) & can't seem to find a way to do this.I am able to draw a rectangle & do a gradient fill, however I need the buttons backcolor property to have the gradient fill rather than a rectangle on top of the button.
create a regular expression. It is a little like a search and replace, I want to replace any string that contains any substring in parentheses with the same string but the words in parentheses colored RED.
Eg Take this text in TextBox1:
"The Prime Minister (that idiot from Scotland) made a speech today"
and convert to this text in RichTextBox1:
"The Prime Minister (that idiot from Scotland) made a speech today"
I was trying to create a custom button that changes the color of the backcolor & the forecolor upon mouse enter & leave the code in the designer as follows:
<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _ Partial Class FocusedButton Inherits System.Windows.Forms.Button
[code]....
but when i press f5 i get the following error message:
Assembly 'D:my projectsFocusedButtonFocusedButtonobjDebugFocusedButton.dll' doesn't contain any UserControl types.
despite i have saved the project to that particular folder & when i try build it gives build succeeded?
I need to create an on-screen shape (circle) that has a fill color, which will blink every X seconds (go from fill color, to white, back to fill color). This is trivial to do...BUT... i want to do it in my own class, so that I can instantiate it numerous times passing it unique coordinates for each instantiation.
How do I do it? Can a class have its own "timer control" in it independent from the form? How would I draw a shape from a class?
I have a problem with inserting a multiple selection option into my Inputbox.
IDEA: First the user chooses an excel file which he wants to open and then the sheet he wants to be read.
I can manage everything else except making the sheet selection a multiple option one.
At the moment the name of the wanted Excel sheet is typed into the text field in the inputbox. But I want the textfield to be a dropdownlist which would be populated with this:
With ComboBox1 For i As Integer = 1 To XL_WB.Worksheets.Count Dim nimet As Excel.Worksheet = XL_WB.Worksheets(i)
[Code]....

I'm trying to rig up a ComboBox with a Datagrid dropdown in WPF. I need the the code to be done programmatically and contained in the codebehind. Here's what I've got so far:
[Code]....
This code produces a ComboBox that contains a DataGrid with two columns and seems to look fine. Although when you click on the ComboBox and select one of the rows in the DataGrid the selection in the ComboBox doesn't work properly. (It just shows the colum headers.) I want the value in the first column of the selected row to appear as the ComboBox selection.
