Add & Remove Listview ColumnHeader Sort Indicator?
Oct 15, 2009I'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?
View 7 RepliesDisable Conversion Of & To Shortcut Indicator (winforms)?
Sep 18, 2010I have a tab control (in my case a UltraTabControl from Infragistics) and I add a new tab.
The text of this new tab is set to "Escape &Characters".
lTab.Text = "Escape &Characters"
When visualizing the tab control the & will become an _ (underscore) for the next character - in this case "C"
I know that & is the Microsoft way of indicating a shortcut character - but is there any way of disabling this behaviour?

VS 2008 Listview ColumnHeader Sort Indicator?
Jun 21, 2011After a long time searching, I am still facing an issue with my listview column header I am trying to add a sort indicator (a small 16x16 arrow, next to the column title - looks quite good).
- My listview is in Ownerdraw mode for : Items & Subitems for a couple of reasons
- So far, I was letting the system do the job for the header (e.drawdefault = true)
I managed to add very easily the arrow using the e.graphics class, right after the e.drawdefault=true, and it is actually working good.
print01.gif
(Sub ColumnHeader OwnerDraw)
e.DrawDefault = True
e.Graphics.DrawImage(My.Resources.fleche_v2_16x16, 34, 2, 16, 16)
As you can see, I'm simply using a resource, and am forcing it to 16x16 with a custom location x=34 pixels y=2pixels My issue comes with the following :
(Sub ColumnHeader OwnerDraw)
e.DrawDefault = True
e.Graphics.DrawImage(My.Resources.fleche_v2_16x16, (e.Bounds.X + 34), 2, 16, 16)
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....).

View 1 RepliesUpgrading Software Written In VB To Include More Graphics/controls/indicator For User Interface?
Feb 18, 2011I have been given a project to update software written in Visual Basic. The software and some files are enclosed in a folder and was written 3 years ago. I have no clue what to do. All I have been asked to include more controls. The user interface allows user to select three processes by clicking on the buttons on user interface. The new requirements is to add two more buttons. There is not much information so I have to use only the resources available. When I tried to open the project, visual studio prompted to convert the project so its compatible with current version. I could open the project but dont know what to do from there. Please guide me towards the right direction. If the project folder is required please advise me how to attach it too.

View 1 RepliesSignal (NOT Cancel) A BackgroundWorker?
Mar 7, 2011Is it possible to send information to a BackgroundWorker thread while it is running? Here is my scenario: Parent thread calls background thread to send a data request to a database. If it's a big complicated query it can take a while for the db to respond, so putting the db request on the background worker thread is great. My app can do other stuff while the one thread waits for the db.
Now, db responds with beginning of data. I want my background thread to report back meta data about the result set to the parent thread. No problem there, I can use a custom user state object and the ReportProgress method. But now, how to I send a signal from the parent thread back to the worker thread? I want the background thread to wait while the parent thread does something, and then tells the worker thread to keep going or quit. I know how to cancel a background thread, but I want the parent to be able tell the child some information other than "cancel". Here's one way to think about it:
