Hi nlarson, Many thanks for the replies,
Here is my actual code,
Private WithEvents mLV As AxMSComctlLib.AxListView
Public Sub Constructor(ByRef LV As AxMSComctlLib.AxListView, Optional ByRef LVWrapper As cListViewWrapper = Nothing)
mLV = LV
......
mLV.ColumnHeaderIcons = frmMain.DefInstance.imlLVSortIcons
......
......
End Sub
1) i can put back the New for mLV
2) Yes, im not using imlVVSortIcons in this form, i want to use mLV
3) frmMain is the main form which contains the imlLVSortIcons image list. And the above code is in different form.
4) Yes, I have created the definstance in frmMain.
Thanks,
AR Reddy

is typeof(columnheadericons) = imllvsorticons?
if your getting somekind of object not set then you'll need to check each one
If lv is nothing then msgbox("it's lv")
If frmmain is nothing then msgbox("it's frmmain")
If frmmain.definstance is nothing then msgbox("it's frmmain.definstance")
otherwise ????????????

I am using Visual Basic Express 2005
I have a main form wich captures several images and saves them to a folder.
Then a secondary form is opened and the user can select in a listbox the image for viewing in a picturebox of the secondary form.
The problem is when secondary form is closed, the image file viewed in the picturebox remains locked (remember secondary form is closed and theorically picturebox is disposed) and only is unlocked when main form is closed.
I have tried explicitly disposing picturebox in when secondary form closed event, with no success.
Thank you

Besides disposing the picturebox, dispose the image as well
oPic.Image.Dispose

i have 35600 records in the database , How should i display the records , so that the screen may not turn white(due to complete CPU usage).
|

1) as far as the display listbox1.suspendlayout / fill / listbox1.resumelayout may help you.
2) consider your design. what is the user going to do with 35600 records? is a "search" feature a better idea the overloading the user with a huge amount of records that most likely they won't need 90% of them at one time?

Lower the number of records you display. Seriously, no one is going to want to scroll through 35,600 records. As in the other reply you got, implement some kind of search functionality.

Or implement some paging functionality. On the first population run
SELECT TOP 50 *
FROM tTable
ORDER BY UniqueKey ASC
on each "NextPage" command run
SELECT TOP 50 *
FROM tTable
WHERE UniqueKey > (last result set's MAX(UniqueKey))
ORDER BY UniqueKey ASC
Try not to do this as it is painful for the DB
SELECT TOP 50 *
FROM tTable
WHERE UniqueKey NOT IN (SELECT TOP [PageCount*50] *
FROM tTable
ORDER BY UniqueKey ASC
)
ORDER BY UniqueKey ASC

Yep. Maybe the OP will take your suggestions, which are very good

Is the project a Windows service or just a regular Windows Forms program? Are you trying to kill the process in code or by using the Task Manager?

Get a profiling tool that will help you understand what parts of your code consume the most resources. There are several that are available as 30 day trialware

Thanks for your help.
If you have any software name, please forward it to me.

Google for ".NET Profiling tool". Pick some. I have tried some of the open source ones within the past year and was really confused (poor docs, not intuitive), so you may want to try one of the commercial products to get started.

Thanks for your reply.
I will look into the matter.
