I'm using VB 2008 and windows vista. I'm using a listview in my application.(view=details) I assign an image list to listview.smallimagelist. when user try to sort the listview by clicking the column header i use the imageindex property to set an icon for that column header, this works fine. When user clicks another column to sort the listview by that, I use listview.columns(PreviousColumnIndex).imageindex=-1 to remove the sort order icon from the previously selected columnheader, but it does not remove the picture from the previous columnheader. How should I remove the icon(picture) from the previous column header?
The arrow wont draw Of course the sort indicator will sometime be on the 2nd column etc.. That's why I need to use the column header's bounds.I can already hear you saying : if you do not owner draw, you can't..But why is it working with a static location (, 34, 2, 16, 16) ans not starting from another static location (e.bounds.x) How can I fix that ? I cant find previous issues similar to that one over the internet.
Points of interest :
- I tryed to load the int value e.bounds.x into a variable before, using that instead of e.bounds.x but it's all the same.
- Using the imagelist is not an option, As you can tell from the screenshot, I am already using images for headers.. the sort indicator is coming as another image
- Using ">" or "<" in the header's text is not an option either........ (sorry pal It does not look good at all..)
- Drawing the header totally in owner draw mode would be an option, but it looks quite hard to do (need to manage the "rounded" header style of the system, the mouse over - small yellow line rounded on the sides in WinXp, the click effect....).
I have a semicolon delimited string (e.g. an EMail Address List returned from a database or a textbox). How do I separate the string into an array, sort, and remove duplicates? The code below works to separate the string and sort the results, but doesn't remove the duplicates. I could probably then loop through the array and copy to a new array to eliminate the duplicates, but there must be a better way to do this using the VB.Net Array, String, and Collections handling classes.
Dim s As String = "Test; Test8;Test1;Test2;Test3; Test8;Test4;Test5; Test6"
What I am trying to do is sort a datagridview and remove a row from its sorted position to the 1st row.
The problem I am experiencing is as follows:
in the source below, when the code runs "MeanRow" is populated with what is required. As soon as Rows.Remove() executes, the MeanRow datarow is lost. Why would this be if I'm declaring a new variable and simply setting it?
Code: MeanRow = r TabGrid(dgv.Name).Datatable.Rows.Remove(r) Code: Private Sub dgv_Sorted(ByVal sender As Object, ByVal e As EventArgs) Dim MeanRow As DataRow
I need the listview in my app to sort by the date (descending) in the second column after adding a new entry to it from another form. I have tried some column sorting examples made for the column click event but am not able to use those examples for what I'm doing as I keep getting error
I'm using the following code to sort a listview:It triggers off the column click envent.What I would like to add to my code is to manually trigger it in the code. My code enumerates all installed apps on a PC and places them into a listview. I then want to sort the listview as the next step in my code but the sort code from the MS site looks for the column which was clicked:
Private Sub lvVisualResults_ColumnClick(ByVal sender As Object, ByVal e As System.Windows.Forms.ColumnClickEventArgs) Handles lvVisualResults.ColumnClick ' Determine if the clicked column is already the column that is

I'm writing an application where as many of other applications fulfill the requirements to be as an app , having it's statistics schema. Thus I made a form where I have a combox(of query category), a textbox(as searchfield), two datetimepickers(from and to) a listview and a button to fire the event with functions in it. I'm all set except for a minor issue I've encountered during my very first experiments with ListView control. Thus far I didn't know that VB users are stuck with that control's property options (whereas DataGridView has way too many), especially when it came to Column reordering/s. With the simple but not satisfying property Sort I couldn't find a proper solution to my issue.
when I click on of the columns in the listview to do a Number/Date/Text reordering (descending>ascending, via-verse). Not to forget to mention there a limited number of columns most likely 2-4 max.
The listview control has lvResults name and has for now columns inserted as "Country" and the other for subitems "Total Spent".
One e.g. of the values inserted to it is like this :
If pressed on Total Spent, should reorder from highest to the lowest number and via-versa. If pressed on Country should reorder from A to Z or via-versa.
I support a .Net 2.0 Windows application that has a custom listview control to allow for greater flexibility. I am not allowed to bring this to a newer version of the gramework until next year. We are moving from XP to Windows 7, and we have identified an issue with how the column sort image (up/down arrow) is drawn to the listview. Currently in XP, the image is drawn to the right of the column's text. However, in Windows 7, I am getting Access Violation Exceptions. Now, I know that the error is with the improper handling of memory using the unmanaged code as shown below. I am looking for a method to mimic what we have below in a safe manner using managed code.
Does anybody have any idea how i can sort a listview by the items backround colour? At the monent the listview looks very messy with all the colours in different places and i dont think the users will be too pleased!!! Iv been trawling the net but cant find anything.
I have a listview that has multiple columns. I am wanting to sort these columns when clicking on the column header.I see there is a sort function, but am not having much luck in using it.How can i sort my listview when clicking on the column header?
Below is the code that will and does add to listview1 when triggered, but, will not remove it. I have spent a lot of time trying to figure this one out. There is not any error even when I step through.[code]...
I am using vbexpress 2008. I have two queries. How a selected item of a listview can be removed? when there are more items than the height of listview an there is scrollbar how focus can be set on the last item of listview every time a new record is added in the listview?
I have an unbounded datagridview with 5 columns. Is there a way of setting the alignment of the header for column 3 only to centerMiddle, while the alignment of the others columns to remain as the default? I have been successful as setting the alignment of each columns, but I could not figure out for the column headers.
If you add a list view, then add a column, and an item, set the view to Details and run it, there will be dots around the item. Those dots will also appear whenever you select an item, along with a highlighted color. I've downloaded projects that don't have them, and when comparing I don't see any difference in listview settings between that and my listview... How do you remove those dots?
