View 1 RepliesTrying to set the viewable area to a smaller screen area and have it cycle through as the person moves using collision detection to move the backgroudn image. Here is the start but its off to a bad start so far.
Public Class Form1
Dim Mapx As Integer = 600
Dim Mapy As Integer = 2000
[code]....
Basically the forum size is set to 600x2000 but the client should only allow you to view 600x600. I want it to add +1 once you "collide with a invisable box I'll add and this will redraw the screen.
Is there a way to disable the user's ability to edit the text in the combo-box, so that they can ONLY choose from the options in the drop-down list?

now the question is: any idea as how to solve the problem?
I'm designing a player application to accompany our phone system. As our calltakers take calls, it makes recordings of each call. They can go to a list module, find a recording and double click, which opens my player. The issue i have is that if the calltaker gets another call, my player doesn't know it and will continue playing. I'm looking for a way to monitor the screen in a particular area and when it sees yellow or red instead of blue, it will pause my player.
The phone system does not have any API's that I can hook onto, so I have to try it another way.
The screen resolution never changes and the queue buttons where they receive calls will always be static. When they get a call, a small area changes from the background color blue to yellow or red to indicate a call.

Basically, right now I have a circle with a line through it that goes across my screen as I drag and what I would like is for it to be the text that I am dragging that drags across the screen, just like a file on my desktop would do when I grab it and try to drag it somewhere else on the desktop. I have put my code in below, how to get rid of the circle with the line through it, and replace it with the actually text that I am trying to drag. I am using Visual Basic 2010

View 1 RepliesI have a custom control with an event handler when you click on it. Everything works and the event get fired right.
AddHandler (cu.MouseLeftButtonDown), AddressOf Me.DoSomething
When the control resizes to show some extra information it expands. It also collapses when the user preses a button. This works alright. But now when I click where the expanded area used to be, it still fires mouse leftbuttondown on that control. I have tried to set IsHitTestVisible to false on the expanded element but it diden't work. Here's some xaml...
<UserControl x:Class="MyCustomControl">
<StackPanel>
<Grid>
[code]....
I cant use another element around my customcontrol since I also use this MouseLeftButtonDown on all different kind of controls.
I can't figure out how the boundaries on the cu.MouseLeftButtonDown event work to fix this.
how to stop a ComboBox from displaying blank data?
The query I'm using does not allow nulls but the ComboBox is showing black areas and the user can click in those areas.
The PureComponents ComboBox did not show the blank areas but when I started to use the ComboBox from VS 2008 the blank areas are showing up.
The attachment shows me clicking in a blank area.

How can i drag already created user control into a form? In a clear statement, i have created a user control. I need to use this user control 2 times and i need to drag it into a form.
I currently using vb 2008 express edition.
I am converting my company's VB6 program over to VB.net and I have hit another stupid little roadblock.
The old program had a ListView docked to the left side of the application screen. The user could place the cursor over the right portion of the ListView, the cursor would turn into the SizeWE arrows, then they could drag it, which would resize the ListView.
I am trying to recreate this. As far as I can tell there is no Property called "Resizable," or at least nothing is popping out to me. I do not believe that it is being done in the code.
Is there a property I am missing? If not, is there an easy way to do this within the code? (ie. is there a event that would make my life easier)
I am using Visual Studio 2008.
Edit: I see how how it was done in the previous program (you always seem to find it once you ask the question, don't you?). The old program had a invisible picture that was only a few pixels wide that when hovered over would change the cursor to SizeWE. You could then drag that invisible picture and that would hit an event that would then change the size of the ListView. This seems rather convoluted. My question still stands: Is there a better way to handle this dragging and resizing?
Im trying to allow the user to drag the text back and forth from labels. The code I have below seems to just show the little circle with a slash through it, and I cant drag or drop the text?
