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>")
...

[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?
I currently have a function that saves a control.forecolor to a file.
The file looks like this:
CODE:
Now, I have another function which retrieves the string "Color [ControlDarkDark]" from the file...But how Can I Apply that color to a control?
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?

It seems the only options available to do multi-color on a string is either a bunch of label controls cleverly grouped together or to use a RichTextBox and play with the font properties as text is added to the control.
What I am looking for instead is some kind of control that can render some style of control codes out as color. Consider bash codes:
NORMAL='e[0m'
GREEN='e[0;32m'
BLUE='e[0;34m'
echo -e "This text is ${GREEN}green${NORMAL} and this text is ${BLUE}blue${NORMAL}"
In the above, the words 'green' and 'blue' will be colorized with their respective colors. I was wondering if there was a control with some kind of feature like this, or will I have to code something myself?
Note, I only have the Express copy of VB 2010, and I would very much like to avoid third-party controls.
I have several questions/problems about Cursors.
1. I have a custom cursor that won't display in color, no matter what I do.
2. Can I have Animated Cursors?
3. Why doesn't VB.net support 32 bit cursors, but only 8 bit?
4. Can I have a cursor thats greater than 32x32?
I am new to 3D modelling. I want to create a simple model from a set of know quad elements (4 sided shape discriped by 4 x,y,z, coordinates). All I need to do is to display the model, rotate it and change the color of each element.

I want to make a small application for my web designing needs that will display the color of the current pixel under the mouse pointer. I need this to work on the entire screen (no matter what form/application is in focus) and it needs to update in real time.
I'm not worried about the math or working with coordinates, but I don't know (and can't find) anything that might get the color of the pixel under the cursor on any form. I've found a small number of VB6 examples, but I'm with .NET 2008. Does anyone know of a method or anything (DLL even >.<)

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.

View 7 RepliesI 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.
