Getting The Color From A String Using Vb.2010
Jan 29, 2012
I am writing a rather large project using the vb 2010, and customer wants to have the opportunity to change the colors of labels, forms etc.
input of color names to a series of ComboBox'es and the ComboBox.text are stored in a database for later use. But now I am faced with the problem of converting those names back to a color. I have used the following codes which is working - but there have to be a more intelligent way of doing it ?
Private Sub ShowColors()
Me.BackColor = SelectColors(rsFormSetUp.Fields("FormBackColor").Value)
Label1.ForeColor = SelectColors(rsFormSetUp.Fields("FormTextForeColor").Value)
[Code].....

[URL] That way if the string that is not recognised that is passed to Color.FromName it returns a SolidColor of
Color.Black = Color.FromARGB(255,0,0,0)
That way, Forms and controls that only support SolidColors are supported.Installing VB6 on Windows 7?

How can i use the color dialogue to return the color selected as a string? So if i was to select red i would like the return to be "Red" and so on so fourth.Another thing i would like to ask is if it is possible to return the color selected as a string in hex color code form (like what is used in HTML for example #FFFFFF, #000000 and so on so fourth).I have a feeling though that it can only be returned as R G B integers but maybe there is a way of converting these to hex color codes?

converting a string to color. i use the colordialog to the user can pick a color, which is then saved into a db. when i load the color to fill a lable it comes as a string. so, how do i convert:Color [A=255, R=128, G=128, B=255] to coloralso, when i use the colordialog, it will save basic colors as color[TheColor] and complex as the one above. to be uniform, is there a way to have the colordialog always return a hex value? or do i need to write a function for that?

I'm trying to convert a chosen color into hex base 6 to save to a config file for later use, and that part works, but when converting back to integer to use for a color, it gives me an error about incorrect base.
Dim hex_color = System.Drawing.ColorTranslator.ToOle(ColorDialog1.Color).ToString("X6")
Dim color_int As Integer = Convert.ToInt32(hex_color, 6)
Panel1.BackColor = System.Drawing.ColorTranslator.FromOle(color_int)

My VB.NET application generates an HTML table with numeric data. I wanted to format the numbers with commas and put brackets around negative numbers. That i did by specifying the format string in the ToString() method. What i want to do is change the color of the negative numbers to red. My sample code:
...
rowHTML.Append("<td align=""left"">" + num.ToString("#,##0.##;(#,##0.##)") + "</td>")
...

How can I change font color of a string. I set the fore color properties of the label holding the string but seems that only works when the string is displayed in that label. Is there a way of setting the color of a string itself such that it displays any where with that color by default. I am actually sending this string as email but wanted to format it in a way that it will display differently however it doesn't.

Well I've been working on a web designer and I wanted to be able to color different keywords and strings enclosed in quotes. Now I've been able to color the keywords but every time I try to color a string in quotes it colors the from the beginning of the document to the end of the quoted string. I've tried looking at samples and apply those methods to the code but it still colors all the text in front of the quoted string as well.This is the sub I'm using to color the text.
Public Sub ProcessText()
Try
LockWindowUpdate(_sourceRTB.Handle)

I have a project im working on and im trying to change the font color of a specific string basically how vb does while your coding. (eg if i type dim it turns blue).I want to do this with a textbox in a vb application to show a topic of interest. It needs to be dynamic so when a user types it only changes the color of the specified string. I have tried
If TextBox2.Text.Contains("dim") Then
TextBox2.ForeColor = Color.Red
End If
but this changes all the text in the textbox to the color.

I'm kind of stuck on this one, and i know it's going to be something simple, but I just can't come up with the solution. I want to be able to assign a background color for each item in a listview with a predefined string or other variable type, so when item's are added to the listview and they contain a specific string, the background color for that item will be changed to the predefined color which is stored in a string (or other variable). When I attempt to change the background color of the listview item using a string ie. "Blue" I get an error.[code]....

i have a listbox that contains the words "week1", "week2",all the way up to "week52" and when i select a week from the listbox it will retrieve a value from a mysql database that will represent a progress bar value. my progress bar has a range of 0-120 and i would like to have all the weeks that have values higher than 100 to be highlighted or marked somehow, in the listbox. so my question is, "is there a way to set the background color of certain weeks in the listbox to orange based on the value that they represent on the database?
for example for "week1", the value is 114, so when the listbox loads, i want the background color of the item "week1" in the list to be orange (indicating that it's current value is higher than 100)? i know that this requires me to implement a user defined drawing function for the listbox items but i dont know where i would even start. i would like this to be somewhat automatic so that it checks the values and changes the background colors of any value higher than 100, instead of me specifying a name of the item.
