i am currently developing a reservation system which has a map locator using visual studio 2008. when the user click in any of the amenities available and a transaction was completed, the color would change. I was able to change it but if you check it for the monitoring, the amenity with completed transaction doesn't change color. my prof said that i have a problem with filtering the data with the date.

Is it possible to change the scrollbars color?
Reason I ask is because look at this:
The scrollbars stand out like a sore thumb.
I am having a slight problem using the color change alongside an if and then value. What I want is for gtotal.text to display in red IF the value drops below a "saved" number previousley used in the program. this number is used as "addicost"
Below is a snippet of the code that is most likely to be wrong. The color of gtotal always displays as red by the way. The only time it displays as black is when it first appears on the screen, but after "recalculating" the number in gtotal, it always displays as red.
If total > addicost Then
gtotal.ForeColor = Color.Red
gtotal.Text = String.Format("Total: £{0}", total.ToString())
[CODE]...
I have now noticed that by calculating in such a way that G total = 0 makes it display in black. So maybe addicost isnt saving properly? which would be insane since I use it at another point in the program okay.
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim AddCost As Double
Dim Total As Double
AddCost = My.Settings.AddCost
[CODE]...
This is how I save addicost

View 1 RepliesI have a combobox called cbMaterialType on a windows form that's bound to a table in SQL - everything loads great and the combobox displays 'Material' items as it should, in that table I have two fields - Material (as mentioned above) which is a char(25) and InStock which is an nchar(1). If the InStock field contains a '1', I'd like the individual material to be green in the combobox, if '0', then red. I have the simple code in the drawitem event of the combobox as follows, but can't seem to get any results at all:
Private Sub cbMaterialType_DrawItem(ByVal sender As Object, ByVal e As System.Windows.Forms.DrawItemEventArgs) Handles cbMaterialType.DrawItem
If MaterialTableAdapter1.GetData.Item(cbMaterialType.SelectedIndex).InStock = 1 Then
cbMaterialType.ForeColor = System.Drawing.Color.Green
Else
cbMaterialType.ForeColor = System.Drawing.Color.Red
End If
End Sub
I've never worked with any form of color in comboboxes before and this is my first attempt at the drawitem event.

What I need is for when you click on a label (for instance), the back color will change, BUT I also want it to change to another color (back to its original) when nothing is clicking it. I can change the color with one mouse click, but when I release the mouse button, it stays the color it changed and doesn't revert back.

I have populated a ListView with currently running processes and with the help of JMC, been able to highlight specific rows based on memory consumption. However, I've decided to change it up a little bit and change the color of rows based on whether the process is owned by the User, if it's a System process, or if is a Service. I've already been able to determine if the process is a User process by utilizing the OpenProcessToken.

I cannot figure out how to change the data in a listbox. I'm being driven completely mad by vb.net, finding it very very complicated.
Ok I have two list boxes on a form that contain correlated data i.e. the first item in the first list box corresponds to the first item in the second list box.
Under the two list boxes I have two text boxes for data entry.
For Example :
LstTagDatabaseLoop LstTagDatabaseSource
TxtTagDatabaseLoop TxtTagDatabaseSource
I want to Add Update and Remove items from the list. If the user selects an item, I want the selected item in the other list to change to correspond. I also want the two text boxes to be udpated with the currently selected item.
[Code].....
however this invoked the selectedindexChanged sub umpteen dozen times and while in the end it did actually update the data, its obviously not the right way.
I found ListViews which perhaps is more appropriate but I couldn't get my head around it at all so returned to trying to use these listboxes. Is there a different object I should be using.
I'm finding vb.net to be too complicated for a hack programmer like myself...
I have a standard DataGridView. One of the columns is a DataGridViewComboBoxColumn. When I select one of the ComboBox items, I want to trap the change and add additional columns based on the item selected in the ComboBox. I've tried using CellValueChanged for the DataGridView column, and a bunch of other events, but none of them is fired when the DataGridViewComboBox value is changed. What event can I trap to make this happen? Right now as I said, I am using CellValueChanged, but of course the event doesn't fire until I click on another cell...
