I am making a diary Form in VB.NET to do this I am using a listview with two columns.
Column 1 consists of a list of time and column 2 is the description
Can I change the colour of certain cells in column 2 only. So when I read in the data from the database it reads in the description and then puts the data in the relevant time slot but I want the recent cells of the description column to be a different colour.
Is there any way to change the default colour to the highlight when a listview row is selected? Apparently the default blue colour causes some problems for some users who have some visual eyesight problems. They didn't tell me what colour they wanted but they did indicated the blue is annoying.
View 2 RepliesI have a custom listview called xx. It has two columns.I want to save the value of the second column to a database, based on the first column
[code...]
Basically that is a for loop reading from the 8th column of the database to the end.
the first column of the list view is populated on form_load with the names of those columns from the database.

I know this is a really noob question but in my program when my button is enabled true/false I change the colour so i was thinking if there is an easier way to do this? or is the following the best way?

I know I'll have to change the 'BackColor' bit but I don't know what to. Is there something that turns all text on the form one colour or do I have to do it label by label?
Also I am can't figure out how to rotate labels to display text at a 60 degree angle (to display along the edge of an equilateral triangle) And for the triangle I have drawn it using lines which move independently from each other, is there anyway to 'group' these lines together so they are fixed.

I have a button (btnAdd) that adds the content of a textbox (txtName) to a textblock (lblName). I want to add a date to the textblock when btnAdd is pressed but I want it to be a different font size and colour. So far my code looks like
lblName.Text = txtName.Text " " + DateTime.Now
I only want DateTime.Now to be a different size and colour. Is this possible? Instead of a label I need to display it in a listBox. My new code:
listBox1.Items.Add(txtName.Text " " + DateTime.Now)
I'm looking for a way to change the font colour on alternate rows within a datagrid. e.g. normal row would be green and the alternate row would be blue. I can change either by using
me.datagrid.Styles.Row.Forcolour
me.datagrid.Styles.AlternatingRow.Forcolour
The problem is that I am having trouble using both of them together as I need to manipulate both colours. I have created a HtmlRowPrepared event and have been setting them there, however, If I set the Row.Forcolour first, it will over ride the AlternatingRow.Forcolour and vice versa. This needs to be done via SEVER SIDE code only as the colour choices are held in the database.
I am currently working on a VB.NET project and the hardest thing that I am having trouble with is that everything is black and blue. Having worked a lot with C#, I really like the way that types are colored differently.
I have tried going in and having a look at the "Tools > Options > Fonts and Colors" and the various "User Types" under "Display Items" is set to a different colour but its not reflecting that colour in the text editor.
I currently have a listview on a forum. The user will select an item and press a button, presenting a second form with data based on their selection. In the event that the user wishes to return from the second form back to the first, the selected item in the list view should still be selected.
I have set the hideselection property to false, but have found that the selected item will be a light gray as opposed to the normal blue. Can anyone please tell me how to change the colour so it will always be blue?
Does anybody have any idea how i can sort a listview by the items backround colour? At the monent the listview looks very messy with all the colours in different places and i dont think the users will be too pleased!!! Iv been trawling the net but cant find anything.

To .NET after getting tired of using VB6 due to the lack of functionality. I'm trying to create a log on method for a system which will involve users selecting a colour from a paint panel and then placing/drawing the colour in 1 or more tiles of a grid, basically a 3x3 grid in which for example they selected the blue colour and drew in the top left tile and the bottom left tile. The logon is selecting the correct colour and placing the colour in the appropriate tile. What i want them to be able to do is place even a single pixel of colour so it has a high accuracy. So far i have a timer which loops from the width of the grid to the height of the grid.
Private Sub Timer1_Tick(sender As System.Object, e As System.EventArgs) Handles Timer1.Tick
Dim BMP As New Drawing.Bitmap(1, 1)
Dim GFX As System.Drawing.Graphics = System.Drawing.Graphics.FromImage(BMP)
GFX.CopyFromScreen(New Drawing.Point(MousePosition.X, MousePosition.Y), _

To start with i have just hard coded the colour i want it to detect. At present it produces an error. Parameter must be positive and < Width the error is on System.Drawing.Point(i,j). If i place the mouse over the colour then run the program it will say it has been found, but otherwise it wont find the colour. I believe i am not updating the location of the pixel or something to that effect.
I've got a combobox which loads the system colour list, the selected colour is stored in the registry (i've tried storing the index number value aswell as the colour name - how can i get the combobox to display the stored colour as the default colour when the form loads? It always defaults to the first item in the colour list I've tried

So I have got a program with a timer on, a few labels displaying coordinates, and two buttons. Here is my

It displays the color of the pixel at the coordinate typed into the text boxes.I have a video of a tennis ball which is bouncing on the spot, and the background in brown, so when the tennis ball comes into view there is a significant color change and i want it to start and stop a timer each time the colour changes significantly.So my question is, how do i get it to check whether the colour chas changed significantly?
this is my very first posting and I must say I am desperate. I have a VB assignment due in 2 days and I am so lost. I have written a code to draw some graphic, just a basic house, tree, sun etc. I have also written a code to magnify said graphics which were all the specifications of my Assignment 1 part A. Now for Part B I am being asked to extend my program so that: A - My graphic can be drawn using different colour schemes designed by me but chosen by the user B - My graphic or an appropriate part of it can be animated around the picture box if the user chooses to do so. C - Error checking is included.

I am writing some data from database to the excel via visual basic.net.I need to change background of some cells and also need to make text bold. I need something like that :

Of course none of above is works.How can I achieve this?
I have a project due tonight and suddenly 2 of my datagridviews are acting funky while the others are fine.
I have 2 tables in an sqlce db. the first is books(id, title, copyright) and the next is publisher(id, name, bookid). I'm writing a vb.net frontend to access the data.
I have data bound datagridviews for both tables. Both have their respective ID columns hidden. The publisher dgv uses a combobox cell style to display the book title in the bookid column. So far so good.
I have suddenly run into a problem where if I have clicked in a cell on the books dgv and then click a cell on another row, the title changes to the id value. The publisher dgv also updates to show the id instead of the title.
It sounds to me like there may be a problem with the booktableadapter or bookbindingsource, but I don't know where to start looking for it. I have a 3rd dgv referencing an unrelated table, and it has no problems. The code for both the working and problematic dgvs are the same (only the control names are different).
what I'm trying to do is read a text file and convert column2 in to lowercase and save it again.
But I get Value of type 'Integer' cannot be converted to 'System.Globalization.CultureInfo'. after .ToLower?
Dim Convertcolumn = From line In System.IO.File.ReadLines("Path")
Select line.Split(" "c)(1) & line.ToLower(1)
