VS 2008 - Highlight Listview Destination During Dragover?
Feb 14, 2010
I would like to highlight the item in a listview that the mouse is hovering over during a drag-drop operation. I'm using a similar method for treeview that works great, but for a listview I'm having trouble. I found a C# example online, but the VB.Net equivalent did not work, unless I translated incorrectly. Here is my
VB.NET
Private Sub AddonDirList_DragOver(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles AddonDirList.DragOver Dim hoveritem As ListViewItem = AddonDirList.GetItemAt(e.X, e.Y) hoveritem.Selected = True hoveritem.EnsureVisible() End Sub
When I use this code, not only does the highlight not work, but the drag-drop operation does not work at all. Rather than the typical drag-drop mouse pointer, the circle with diagonal line pointer is shown, which is what you would normally see if the listview did not have dropping enabled.

Does anyone know why a ListViews dragover event does not fire when dragging over a listview column header or an empty row?I'm trying to highlight the row a user is dragging over. Everything works with the exception that when I drag over the column header or an empty row the previous row stays highlighted since the dragover event doesnt fire. Is there another event that I should be looking at? I've checked the hover over and it doesnt fire either.

I have a ListView that I populate with running processes and would like to highlight specific rows based on the amount of memory consumption. After I add the processes to the list and and call the WorkingSet64 property of the process, I tried this:
vb.net For Each lvi In ListViewProcess.Items If proc.WorkingSet64 >= 2000 Then lvi.BackColor = Color.Yellow End If Next
Processes is the variable I used to grab the collection of processes. proc is defined as a variable and then used to loop through the processes.
lvi is of course the ListViewItems in the ListView.So, by the code I have above, I loop through the ListViewItems, and if any of the processes are above or equal to 2000, then I set the background color to Yellow.
However, it sets every line to yellow, and I can't seem to figure out to set only those processes that have a WorkingSet64 above 2000.
Would I need to loop through the processes and then set the background color of the ListViewItem based on that? That kind of makes sense to me, but if I do that, I'm not sure how to set it just for those processes. Maybe by setting a separate variable?

I have a Listview that will display all System Services on the local machine. I also have settings to change states of the services as a group as well as single selected item. My question is, Is there any way when the user selects which option to change, to highlight all the services that were changed in the listview, making it easier to see what the user has changed .

I am using this code:
[Code]...
It even indicates if the string I'm seeking is in the middle of a line. But what I would like is for the routine to highlight the line that that string is in and ensure visible. I can do that with another routine that uses an integer, but then the whole string(line) has to be the searchString. I've tried combining the two and even calling a Private Sub but with no success:(What is the best way to do this? Also, how do you get around doing it when the searchWord in in several lines?

I can search for items in first listview column using FindItemWithText. I wonder is it possible to search in other listview columns and highlight found text, not all item line? My Listview contains multiple items and each item has 9 subitems. I would like to search in column 4.

I have tried many different ways to make this work. Every attempt causes a pause where the drag operation is not recognizing the drop sites under it. There are many long narrow flowLayoutPanels that allowdrop of my button. I am basically wanting the scrollbar(vsFLP_UnitPanel) to scroll if the condition is met. It works, but for some reason there is a pause when the scroll begins.
Try
If e.Data.GetDataPresent("myButton") Then
Dim show As Integer

I am using the Streamwriter to send simple messages to other machines in my office. But i hit across a problem today which i never thought about. If the computer im sending the message to, doesn't have the listener running, the sender crashes out. Is there anyway to trap the error, and deal with it nicely (i.e a message box) instead of the app quiting?

When I exclude a block using #if #endif in VB.Net there is no visual evidence that the block has actually been excluded unless I indent the block and it does not return to the left margin. I checked the active settings for Fonts and the Excluded Code colorization is identical to that of C# and C++. However, the block is not colorized at all. VB clearly knows the block has been excluded, but I cannot figure out how to get the block highlighted as it is in C# and C++.

I am not sure if it is possible, but I would like to be able to provide a custom "SelectedHighlight" color when an item is selcted in both a treeview and a listview (Better yet, any) control.
While I am a fan of sticking with established convention in most cases, There are times and places when I would like to do this.
A. Is it possible to do this? And by possible, I am looking to Override the Default system SystemHighlight at runtime, for only a particular control. I am NOT looking to change global system settings (at least, outside of any time when the particular control has the focus.
B. I haver tried a few searches, and I will contiinue (Try searching for any combination of "System", Color", "Selection", and "Highlight" and see what comes back!).

I am trying to make a program that would allow me to track all my customers and flights. My idea is to have a label for every seat of the plane. Then I would want it to highlight and turn green when the ticket's barcode is scanned.I think it would be cheaper to do it this way then to buy some corporate software.

I am working on an an explorer form project where I have one treeview and one listview. I have all of my drag and drop functionality working as expected. However, I would like to highlight the treeview node the user is hovering over when draging items from one folder to another. This is the same functionality as windows provides in windows explorer.
Thus far I have been successful in changing the backcolor of the node using the dragover event. However, once I move away from the node, the backcolor does not change back to white. I have looked at the dragleave event but my code does not seem to work in reverse. how I can change the backcolor after moving away from a node?
Private Sub TreeView_DragOver(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles TreeView.DragOver
Dim loc As Point = (CType(sender, TreeView)).PointToClient(New Point(e.X, e.Y))

I am trying to read through some code and it would be helpful if the editor in VS 2008 would highlight the If statement by using the cursor and double clicking the End If statement (or something like that).
I believe I could do something like this in Java using Eclipse - it was very good at highlighting a code block by clicking next to one of the curly braces.
