VS 2008 Highlight Rows In A ListView Based On Specific Conditions?
Oct 12, 2009
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 want to change the row color of every row in my DataGridView where a particular column value = "RBF3". I am currently using the DataBindingComplete event which seems to work fine, but it fires every time I change a cells value. I'd like for this bit of code to only fire when the datagridview is first displayed, sorted, or filtered. Is this possible?

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.

deal with ever changing SQL queries based on various conditions? i am using Cmd.BindByName = True so it doesn't need to be in an ordered way when adding parameters. Just that this is the hectic way of doing the update SQL ..or even worse insert SQL/I favor doing parameters instead of using stored procedure bcoz i find it faster by using parameters .
SQLStr.Append("Update Table set col1 = :time ")
Cmd.Parameters.Add("time" , OracleDbType.Varchar2)
Cmd.Parameters("time").value = "xxx"

Let's say I have items in my WinForms application which have an expiration date. I have more different conditions than this one but let's do it simple. I'd like to trigger an event when an item comes to expiration. What is the ideal way to do so? Checking every X minutes?

I have a MySQL database which acts as a source for a datagridview, is there anyway I can set colors to the rows based on values in a cell? So that if the value in a row in the field "Priority" is "yes" then the row is red?

I am working on Treeview control and Gridview Control VB.NET08. In the Treeview i have Parent and Child Nodes. Like: [Code] Comparing the Parent Node text and first two digits in the Column values. I want to add rows inbetween the gridview rows based on the parent and Child Nodes. If i expand the First Parent Node Called "31" then according to the Number of Child Nodes (for first parent node(31) there are 5 child nodes.) add rows in the gridview.
These New rows should be add under the 31-xxxx. If i expand the 32 Parent Node based on number of Child Nodes, add rows under the 32-xxxx. [Code] I am getting the rows in the end of the Gridrow not in the Specific row.

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 have the code listed above as a translation from a Java snippet. The problem i have is that in Java, my table was stored as a dataset and as such, the methods were easily identifiable by "getRow" and getCell" using specific numbers and column names. However in VB the information is stored in an MS Access database (which i already have an open connection to, called: "_SalesPerformance_AnalyticsToolDatabaseDataSet12") and as such i do not know the correct way in which to iterate through each row in the database, checking a specific column against an already specified variable and then returning an integer based upon the value of a seperate column in the same row.

I wanted to identify the conflicted schedule of each of the section. If there's conflict then the two or more subjects that are conflict will be colored to make then noticeable. They are in datagridview. I don't know what's wrong but there are some that although they are conflict they are not highlighted. Here's my code:
For item As Integer = 0 To DataGridClass.RowCount - 1
For item2 As Integer = 0 To DataGridClass.RowCount - 1
If DataGridClass.Rows(item).Cells(ClassID).Value <> DataGridClass.Rows(item2).Cells(ClassID).Value And

I am creating a project in VB.NET in which one of the reports require that the name of employees should be displayed as column names and whatever work they have done for a stated period should appear in rows below that particular column.Now as it is clear, the columns will have to be added at runtime. Am using an ODBC Data source to populate the grid. Also since a loop will have to be done to find out the work done by employees individually, so the number of rows under one column might be less or more than the rows in the next column.Is there a way to create an empty data table and then update its contents based on columns and not add data based on addition of new rows.

I'm currently grabbing all files in a folder and displaying them into a listview. Below is the code I'm using:
[Code]...
If you look at the "For" line, you can see that pulling all files with an extension of .txt. There are some files that I need to pul with different extensions. I tried just doing "*.", and it would grab the files with not extension, but not the txt extension.
So, I wanted to know if there was some way to just pull all files or specify more than one extension.

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:

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?
