I have a TextBox that displays a color as its background color and the background color code in its text. I have set the text color as Black.The problem is that if the user sets the color as Black then the color code will be unreadable. How do I set the text color programmatically so that it becomes readable when the user selects any color?

View 2 RepliesI have a array of pixels. And I would like to Quantize them.
For Example
FF00FF,00FFFF stuff like that, but most are custom colors and are not a standard 256 color palette. So I need code to convert a color to a 256 color. I dont have any idea on how to do this, but thats why I came here. I do not want to use System.Graphics.Image.Palette or anything like that as this project uses arrays for images. I would like to if at all possible be able to convert a R, G, B color to 8bit, 16bit, 256bit and possibly use the HSL or NeuQuant method or something close to that, or maybe even some other methods of doing it. I do need to be able to do this for a single pixel, but I will also need a method for a array of them.
I have a windows form that has 18 checkboxes named CheckBox1 -> CheckBox18. Also i have a text file that i want to use to store whether the checkbox was checked from a previous session.[code]Now say 002's seventh character = 1 i want to to be able to change CheckBox2.checked to true without having to put in a long if..elseif... statement - so i need to somehow get the checkbox name to change dependant on the the first three characters.[code]

I'm in a bit of a bind with this project I'm currently working on. I'm making a 52 card deck counter, so the first code I whipped up was an array to create checkboxes for 13 cards of each of the 4 suits.
Dim x As Integer = 10
Dim y As Integer = 440
Dim width As Integer = 150
[CODE]............
The problem is I can't figure out for the life of me how to use the contents in cards(k, i). Anyone know how to initialize event handlers for that array of checkboxes?
Something like:
[CODE].........
But again, I have no clue how to get the script to detect when a cards(k, i) is checked.
i want to insert checkbox text only if they are checked.[code]This code will add all checkboxes whether it is checked or not..so that only checked checkboxes would be added in array list
View 1 RepliesI've created a treeview that is going to represent a 'table of contents' for a Word template I use frequently and I need to add checkboxes to each node of the tree view.
Here is some of my code so far:
tvwSIGtemplate.Nodes.Add tvwSIGtemplate.Nodes.Item(2), tvwNext, , "3. Statment of the Issue and Solution"
tvwSIGtemplate.Nodes.Add tvwSIGtemplate.Nodes.Item(3), tvwChild, , "3.1 Issue Details"
tvwSIGtemplate.Nodes.Add tvwSIGtemplate.Nodes.Item(4), tvwNext, , "3.2 Solution Details"
What to add to these lines to simply display a checkbox next each line?

View 2 RepliesI have a ListView with the columns 'Name', 'Expected', 'Total', and I want to add another column saying 'Recount' at the end. The 'Recount' column will ideally have a checkbox only if the 'Expected' value is larger than the 'Total' value.
So far I have got the ListView with columns and can add a check box on the left hand side, but that check box is not under a column heading (though I can probably put another column with no values in there to work around that) and it is on all of the records.
I need a way to have 3 colums of checkboxes inside a checkedlistbox. I know i could do it with a panel, labels and checkboxes. But having them all in the control would be more convenient. I'm pretty sure there is no direct way of doing this, so i assume i need to create a user control. If you're not completely sure what i'm trying to create, i'm going for something that looks like this: [URL]

View 5 RepliesI want to have my current row stand out as the current row by virtue of the background color.I also want my current cell stand out from the row color.
in other words i want to controll the background of the current cell as well as the current row, and have these colors different from each other as wel as the background from the non current cells.
I am getting confused with the notion of the current row vs the selected row.I have tried messing with the default row style.selectedbackgroungcolor as well as the same for the default cell style, but cant get it to work the way i want.
i can almost get it if i set the selection mode to full row, but then cannot get the current cell to have a different background color.
if i wanted to make the text of an array index in to a colour. I mean
str1(0) text value is 45673
str1(0) = color.blue
so i would like the out put to be 45673?
Suppose i have an image and i extract each pixel color and store it in a color array, is there any way by which i can save the color array along with the image? I was thinking about converting the color array to string and then integer and then append data to a text box, but then again i must store the text along with the image....and i dunno how to do that?
View 1 RepliesI have created 3 arrays of buttons for a form which manipulates the value in a combo box or 2 by the name of the button ( buttons named 2 through to about 70 )
This works great but the problem is, now that the buttons are in, I want to be able to change the color of the buttons when another button is clicked
ie. The first bunch of buttons is a list of locations all with unique text.the second bunch of buttons is events that happen, sign on, sign off, beach open and beach closed.
What i want to be able to do is change the color of the button clicked "before" i click sign on, sign off, beach open or beach closed.
I do not know how to reference these buttons in my code as for starters, they are numbers, which is a big no no apparently. Also, even if i change the name from just a number to something like cmdBeach(i) when creating them, i still can't refer back to cmdBeach5 in my code as the button doesn't exist yet
I have a form with a lot of LineShapes on it, and basically what I'm trying to do is make certain lines a blue colour and others a black colour, depending what it's in an array of integers. Each line is called line1, line2 etc. So if one of the values in the array is 3, then line3 would be coloured blue.
I have the following code to handle all the lines more easier:
MeterArray = New PowerPacks.LineShape() {line1, line2, line3, line4, line5}
However, since I'm going to have about 50 seperate lines, this is going to look quite messy when I reach line50. So my question is, is there a tidyier way of handling these lineshapes.
I've created a program that requires students to answer addition questions.I have the code so that it calculates if the answer is correct, along with outputing the correct answer into a textbox.If the answer is correct the textbox background colour changes to green.If the answer is inocrrect the textbox background colour changes to red.I've done this using an array, and I want to use this array to calculate how many questions the students have answered correctly, and output them onto another page.I'm not sure is something like this would work:I was thinking about giving the textbox that outputs the grade score a value of 10. For every red box that is highlighted, 1 is taken away from the texbox value, outputting the amount of questions the user has answered correctly.Here is my array so far, not including the ability to output how many answers the student has answered correctly.
Public Num1(10), Num2(10) As Integer
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

I have a small project that requires me to have a font dialog, a color dialog and a print dialog. It has four text boxes that are formatted based on the font from the dialog and the color from the other dialog. I am to print it all out with the same font and color. I have easily put the font in the right place and have the rest of the print set up, but the DrawString wants Brushes.<color> for it's color. How do I make it the same color as in the text boxes? I am not trying to get you to do my HW for me, but everything I see online is the brushes or shapes... if you could suggest something to look into that would be great, but I doubt my grade would be much affected by my printing everything with Brushes.Black like everyone else in the world seems to be doing...
