I'm working on a playlist and would like to have 2 different highlight colors. I'm using the DrawItem Event with the following code..
Private Sub PlaylistBox1_DrawItem(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DrawItemEventArgs) Handles PlaylistBox1.DrawItem
e.DrawBackground()
[Code]....
I want the item above the selected item to be highlighted in red. Basically what I'm looking for is the select item is green"next cue" and the previous item is red meaning it is currently playing.
I am working on a page where I need to highlight different events in a day with different colors in a ASP.NET Calendar Cell. The events are store in a database with a start date column.
For example, if we have two different events for today, the cell should display half green and half red color. If there are three events for today, it would 1/3 green, 1/3 red, 1/3 blue in the cell for today.
In addition, currently I use tooltip in jquery to hover a cell, it would display a tooltip above the cell. How to handle this when we have different events in one cell?
I know how to have alternate row colors with ListView. But how about with ListBox? I've run a search. I read in some web sites where they say you can't. Is that true? Meanwhile, I've done something like: For i As Integer = 0 To ListBox1.Items.Count - 1 Step 1 If i Mod 2 = 0 Then ListBox1. BackColor = Color.FromArgb(150, 250, 255) Else ListBox1. BackColor = Color.White End If Next i with ListBox's DrawItem event. And it doesn't work.
Im currently faced with a problem. I have a textbox whereby the user would enter a word, my program would then match the word within a text. If there is a match, the program would display the word and the line that contains the matched word in the listbox. My problem is I want to highlight that particular word when the line is displayed in the listbox but I could not find any syntax that could perform that function.
I am currently working at an, as the topic tittle says, ListBox control, writed in pure GDI to inproe my GDI skills.The problem is the ListBox items (defined as ListeItm), i tryes to make the ListBox items to show up every other in two different colors.
To do so, i have created a boolean called "lf". When the ListBox item is created it checks what the value of lf the last Item got, and chose the opposit, but somehow, it is not working.

I have a small code and i want to highlight not only one found item in listbox but to highlight all items found under typed keywords.
Example: i typed vb.net programming and i wanna to find it all keywords under these names and highlight only those sites and put those keywords in textbox2 from textbox1.
I want like this:
Here is the code.
For i = 0 To ListBox1.Items.Count - 1 If ListBox1.Items(i).ToString.ToLower.Contains(Trim(LCase(TextBox1.Text))) Then ListBox1.SelectedIndex = i
I have made a little application for me and my friend to be able to chat with eachother, but now we have some unclear strings as you can see on the image below:
I would like to change for example the username or time date to a color or make it bold, could anyone tell me how to change ONLY that and not everything? I'd love to have such a thing as it makes the whole application way 'clearer'.
The code below creates a highlight rect on each of the selected items in a listbox. How can I do the same without selection but rather on mousemove above an item?
Private Sub ListBox1_DrawItem(ByVal sender As Object, ByVal e As System.Windows.Forms.DrawItemEventArgs) Handles dialogue.DrawItem If e.Index <> -1 Then e.DrawBackground() If (e.State And DrawItemState.Selected) = DrawItemState.Selected Then
i have this app. with a listbox , a save button, and 2 textboxes the listbox loads all the files in a folder that i save directly from my save button it automatically loads up the files when i click on a listing in the listbox, text1 is the file name, text2 the content.i want to be able to have the listbox highlight the new saved file name in the listbox once i save the file in order to show that the file was created and such.
If I set a ListBox.Height = ListBox.PreferredHeight when the control is hidden and IntegralHeight = True, then set it visible:
a) Actual Height reduces by typically 3-5 pixels after redraw (but not 1 pixel per item).
b) PreferredHeight does not not appear to give the correct integral of item heights.
Is there a way to make ListBox calculate the correct integral Height before the ListBox is made visible, so it can be correctly pre-positioned from bottom edge?

I'm creating a little program to help my students to understand colour-mixing in Hex for their Web Design course. What I've got so far, is as follows: The user is presented with 3 sliders (one each for R, G and B) and a button. The 3 sliders each go from 0 to 15 - and when the user hits the "Show me!" button, Select Case jobbies translate the 0 to 15 values as seen here:
this is what i need to do: In the right-hand label, invert the colors of the image. Hint: the inverting white should give black and inverting black should give white. Inverting red (255,0,0) gives cyan (0,255,255). visual basic express 2008 this is what i have, what do i need to make changes to in order to accomplish this?
I am working on a program to generate 50 circles starting with the smallest in the center of the form. The circles do not over lap and the appear to grow outward. Each circle has to be a random color. I have the code that generates what I need but all the circles are the same color. I was thinking about either using an array to hold each circle and color as to not assign the same color to all of them but not sure about putting a graphic in an array. I also think maybe a nested loop of some sort but was unable to figure one out.
Private Sub mainForm_click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Click Dim penColor As New Pen(Color.FromArgb(Rnd() * 255, Rnd() * 255, Rnd() * 255, Rnd() * 255), 2)
[Code]......
This works to do what I need to get done, I just need each circle to have a random color as it is drawn.
Essentially I am searching an array for colors. If there is no input, on button click you get an error. If the color does not exist you get an error. If it exists then it tells you. The latter two events are not happening.
