View 3 RepliesJust started using Visual Studio 2008 and was hoping to convert my VBA UserForms to VB.NET with the intent of upgrading my antiquated UserForm controls to newer Windows form controls that match the operating system.The Windows forms I create in Visual Studio look great, but when I load them in PowerPoint or Excel, the form controls look just as ugly as they did before (e.g. plain, rectangular buttons).
View 1 RepliesI have a form with a listview on it. Listviews are very versatile beasts with all kinds of odd options to them, so I'm not sure if this is working the only way that it can, or not. The issue is that when I select one of the items in the listview, only one column (of two) is highlighted. I'd prefer a selection appearance similar to using a DataGridView where the whole row is highlighted. Of course, one option would be just to switch to a DGV, but that would require a bit more code to get the column widths right. So my question is whether there is some setting to get what looks like full row selection appearance in a multiselect ListView?

In Microsoft Access there was an easy method to turn off screen updates by setting Echo = False. Is there an equivalent in VB.NET for WinForms? I've got a situation where I'm trying to prevent users from seeing controls flickering while they're being updated. I could probably solve the problem by coding it differently, but would rather avoid it if I can.

View 1 RepliesTo recreate this behaviour, you need to create a pop-up form with the following properties:
(1) ShowInTaskBar = False
(2) Display the form with the Show method and loop until the form is not Visible.
(3) In order to close the form when the mouse is clicked out of it, override OnDeactivate, and set visible to False.
Next, create another form that will display the pop-up when a button is clicked:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As Syste
Using pop As New PopUp
pop.Visible = True

With vb.net code, how can I get the Windows "Appearance" properties - specifically, see if appearance is "Windows Classic Style" vs. "Windows XP Style"? I've seen a couple threads about this regarding getCurrentThemeName, and the use of some dll import ('uxtheme'), but I'm not making heads or tails out of any of that. I would have thought this info was easily obtained..

I have a winforms app using a trackbar. The BackColor property is available for change, but doing so makes the color of each "tick" almost invisible. I don't see an explicit property to modify the color of the "tick". Is there something I am missing or a way to change the color of the tick?
View 1 RepliesI would like to specify a function to be called in my VB.Net 2005 WinForms project at midnight when the system date changes. Is this possible?I know I could do this by setting a timer by setting the interval to midnight minus the current time, then after the first tick, setting the interval to 24 hours. I was wondering if there was a cleaner, simpler way.

Let me try to describe my problems in the simplest way: I have combobox1 and combobox2. I hope to achieve two things: Combox1 is bound to list1 (a list of string). When a user selects an item in list1, list2 (a list of string) will be obtained from database and combobox is bound to list2.If user specifies text1 in combobox1 and text2 in combobox2, then these two values will be shown in the comboboxes regardless of the bound lists.
[Code]...
So the results of above code is that goal 1 is achieved, but goal 2 is never achieved. combobox1.selected index is always 0 and combobox2.selected index is always 0 too.
