Hi
I have done this in my previous project successfully. Now I am doing this again on my current project and it does not display groups. although ShowGroups property is set to true with view property = details.
The code is
Dim lg As System.Windows.Forms.ListViewGroup = lvAll.Groups.Add("abc", "abc")
Dim lstSC As New ListViewItem("xyz")
lstSC.SubItems.Add("xyz1")
lstSC.Group = lg
lvAll.Items.Add(lstSC)
' where lvAll is listview name
I copy pasted the listview control from my previous project incase I am missing any property but it does not work.
Any Suggestions would be highly appreciated.
Regards

ListViewGroups only work on XP or above. They don't work on Windows 2000 and below. In addition, you're application must have previously called Application.EnableVisalStyles() and the ListView's View property must be set to anything other than View.List in order for groups to work.

i m developing an application and 50% completed bt the memory usage at this time is too high its abt 40MB  y is that so? how can i solve the problem?

use less memory.
What other advice did you hope for, you've not descibed your app at all. 40MB is not a whole lot, given that it includes the runtime. I think you need to just relax, in all likelihood

Wouldn't System Temporary folders (TEMP) satisfy this criteria? But I don't think they are by default shared, unless you share them explicitly or through an Administrative Share.

Shared folders?? No, there are none.
You'd have to create a folder, Share it yourself, and set the appropriate permissions on the Share and NTFS sides.

hi All again i managed to solve my previous adapter. as Acces does not support substring function, i used Mid instead. so now i have problem in my search button. and the Problem is Poiting to the following line.
damixed.SelectCommand.Parameters("Boundary_Area").Value = cmbboundary.Text
damixed.SelectCommand.Parameters("Lis_key").Value = txterf.Text
i used "mid" function to Extract the value to is needed to be searched. like this
SELECT Boundary_Area, Compl_Boundary_Area, Extension, Current_Values, Improvements_Value, Improved_Value, First_Prop_Address, Lis_key, Num_key, Own_Name, Parcel_No, Parcel_Portion_No, Primary_ID, Prop_Address, Purchase_Date, Site_Value, Street_Name, Street_No, Actual_Extent, Title_Deed_No, Values_Effective FROM Property_ValRoll WHERE (Boundary_Area = ?) AND (MID(Lis_key, 5, 5) = ?)
When i run project code, it tell me that
An OleDBParameter with Parametername 'Lis_key' is not contained by this oledbParameterCollection.
As you can see am connecting to Acces database,i had a same project that is successfully but DB as SQL, so the code will differ in the adapter and in the parameter. So please tell me if its the correct way to get input from a user's textbox and combobox this way? and what is wrong with my code.
Thank you

OleDb doesn't use named parameters. You have to create the parameters and assign values to them in the order they are seen in the SQL statement.

i understand, please Post an example code.
Thanks

Hi ,
I have some problems. I have sql query that join tables and show results based on Date value of a table in the join. I can create crystal report using that query directly. But, that's not what I want. I want to pass the Date parameter from vb.net. I'm using visual studio 2003.
My query is like this,
Select Table1.Description as 'Name', Sum(Table2.Fee) as 'Amount'
From Table2
INNER JOIN Table3 On Table3.xxxxID = Table2.xxxxID
INNER JOIN Table4 On Table4.xxxxID = Table3.xxxxxID
INNER JOIN Table5 On Table5.xxxID = Table4.xxxxID
INNER JOIN Table1 On Table1.xxxx = Table5.xxxx
WHERE Session.EndDate between '01/01/2007' and '12/01/2008'
Group by Table1.Description
Please help me,
Thanks in advance,
RB

Create your own custom-drawn control. This is not an easy feat if you're unfamiliar with drawing, or creating controls. As with any application, creating controls has two sides to it. Managing the data model and drawing the control. After all, there's nothing to draw if you can't manage and understand the data your representing with the graphics.

I don't know of any free ones.

The file may not be there either in GAC (as shared assembly) or in bin folder (in case of private assembly).
Also
1) Wrong Forum.

Bascially, if you didn't load the DLL into a new AppDomain, there's no way to unload the DLL.
