Just curious... [modified] Colin Angus Mackay17-Jul-07 0:09 Colin Angus Mackay 17-Jul-07 0:09  Why am I getting all these one-votes for my answers? I thought the answer above would be quite useful. The link I gave gives a good overview of the subject then links out to two excellent, and more in depth, articles on the subject. If I have somehow managed to offend someone I'd like to know what it was that caused such offence, because, quite frankly, following me around the programming forums voting practically everything I post a 1 is childish in the extreme. -- modified at 7:45 Tuesday 17th July, 2007 Surprise, surprise! This post gets voted a one too. Upcoming events: * Glasgow: Mock Objects, SQL Server CLR Integration, Reporting Services, db4o, Dependency Injection with Spring ... "I wouldn't say boo to a goose.

You have to enumerate the rows in the table, adding up the prices, and you can also delete each row in the datatable, then call the update method on the dataadapter for this datatable/dataset to write the changes back to the database.

Prasad listview smallimages disappear ESTAN16-Jul-07 12:01 ESTAN 16-Jul-07 12:01  Hello, I encounter strange phenomenon with my listview and smallimages. The images disappear and don't come back, even after reboot, run the application on a different machine. If i create a new listview, it works again for a while. Does anyone can help me with this annoying thing. The imagelist has 2 images and when i replace the listview i reuse it. Here you have my code, first the declaration of the listview, and second, how i add during the program one element. Thanks for to take a look into this. Declaration: ' 'ListView2 ' Me.ListView2.AccessibleDescription = resources.GetString("ListView2.AccessibleDescription") Me.ListView2.AccessibleName = resources.GetString("ListView2.AccessibleName") Me.ListView2.Alignment = CType(resources.GetObject("ListView2.Alignment"), System.Windows.Forms.ListViewAlignment) Me.ListView2.Anchor = CType(resources.GetObject("ListView2.Anchor"), System.Windows.Forms.AnchorStyles) Me.ListView2.BackgroundImage = CType(resources.GetObject("ListView2.BackgroundImage"), System.Drawing.Image) Me.ListView2.Columns.AddRange(New System.Windows.Forms.ColumnHeader() {Me.clh_1, Me.clh_2, Me.clh_3, Me.clh_4, Me.clh_5, Me.clh_6, Me.clh_7, Me.clh_8, Me.clh_9, Me.clh_10}) Me.ListView2.Dock = CType(resources.GetObject("ListView2.Dock"), System.Windows.Forms.DockStyle) Me.ListView2.Enabled = CType(resources.GetObject("ListView2.Enabled"), Boolean) Me.ListView2.Font = CType(resources.GetObject("ListView2.Font"), System.Drawing.Font) Me.ListView2.FullRowSelect = True Me.ListView2.GridLines = True Me.ListView2.HeaderStyle = System.Windows.Forms.ColumnHeaderStyle.Nonclickable Me.ListView2.ImeMode = CType(resources.GetObject("ListView2.ImeMode"), System.Windows.Forms.ImeMode) Me.ListView2.LabelWrap = CType(resources.GetObject("ListView2.LabelWrap"), Boolean) Me.ListView2.LargeImageList = Me.ImageList1 Me.ListView2.Location = CType(resources.GetObject("ListView2.Location"), System.Drawing.Point) Me.ListView2.Name = "ListView2" Me.ListView2.RightToLeft = CType(resources.GetObject("ListView2.RightToLeft"), System.Windows.Forms.RightToLeft) Me.ListView2.Size = CType(resources.GetObject("ListView2.Size"), System.Drawing.Size) Me.ListView2.SmallImageList = Me.ImageList1 Me.ListView2.TabIndex = CType(resources.GetObject("ListView2.TabIndex"), Integer) Me.ListView2.Text = resources.GetString("ListView2.Text") Me.ListView2.View = System.Windows.Forms.View.Details Me.ListView2.Visible = CType(resources.GetObject("ListView2.Visible"), Boolean) Add element with imageindex set on 0 Dim item As New ListViewItem("") ' 0 item.ImageIndex = 0 item.SubItems.Add("-") ' 1 item.SubItems.Add("-") ' 2 item.SubItems.Add("-") ' 3 item.SubItems.Add("-") ' 4 item.SubItems.Add("-") ' 5 item.SubItems.Add("0") ' 6 item.SubItems.Add("0") ' 7 item.SubItems.Add("0") ' 8 item.SubItems.Add("No") ' 9 Me.ListView2.Items.Add(item) Re: listview smallimages disappear Tom Deketelaere16-Jul-07 21:06 Tom Deketelaere 16-Jul-07 21:06  I don't immidiatly know why you're images disapear but I'd start by trying to figure out when exactly they disapear (after a specific action or time) also try triming you're code to the minimum (perhaps even rewrite some in a differant project and see if the same happens there) since I'v never encountered this before (and I'v used listviews with images a few times before) I would think that somewhere in you're code there is a mistake that clears the images from the listview or the images from the imagelist so I'm afraid this might be one of those trial and error debugging things Re: listview smallimages disappear ESTAN17-Jul-07 1:45 ESTAN 17-Jul-07 1:45  Do you think that all these lines are normal? For example: CType(resources.GetObject("ListView2.Dock"), System.Windows.Forms.DockStyle) It is referring to the resources file, I am a C# programmer, but I have to make something in vb.net and in .NET 1.1, so I am using VS2003. I never saw this before. Another, if I change the listview, i have images for a while and than it falls back to its old habit. This sucks. I'll try to figure out what is causing this problem. Re: listview smallimages disappear Tom Deketelaere17-Jul-07 2:11 Tom Deketelaere 17-Jul-07 2:11  did you import you form or did you start from scratch, added the listview, set its properties,...? it is possible that you get strange code like that from the designer when importing a form or when copying a control (I don't know why or how but it doesn't always work) if you did copy it or import it I would suggest you make a new project and start from scratch there (not you whole prog just the bit with the lisview code) and see if you still have the behavior you described if so then something is probebly wrong with the code if you don't get that behavior and you copyed it or imported it then that is probably the reason if you could providy more detail about all this I might be able to reproduce the behavior and help you further Re: listview smallimages disappear ESTAN17-Jul-07 4:49 ESTAN 17-Jul-07 4:49  Well what i do is i drag a listview from the toolbox on the form, set the options that i like one by one, and between I run my code in order to see where it goes wrong. And the conclusion is that i arrive to what I would like to have and the images are there. In the meanwhile i am creating other classes, not really working on that form, and on a sudden debugging the images are disappearing. Pff, I don't know what is going on. Re: listview smallimages disappear Tom Deketelaere17-Jul-07 5:00 Tom Deketelaere 17-Jul-07 5:00  Then I'm afraid I'm at a lose aswel the code you pasted above shouldn't have been generated if you draged it from the toolbox (there should have been a very differant looking code) all I can think of is recoding that part (delete the listview and put it back set its properys, name it the same as before so that you're code still works) sorry I couldn't be more helpfull Re: listview smallimages disappear ESTAN18-Jul-07 22:28 ESTAN 18-Jul-07 22:28  Well, i am perplex myself also. I go to finish the application and recreate it from scratch, because i don't know what is going on. Damn, i wish i could program in VS2005 Thanks anyway for looking at my problem. What would be better? Cory Kimble16-Jul-07 11:08 Cory Kimble 16-Jul-07 11:08  I want to pull data from two tables with a restriction on one field (only if a certain value). I want to then load into a dataset. Then be able to filter. Then offer user to change fields and write back to the database tables. What would be the best way to do this? I thought I could run a query to get the data in one table and then load into a dataset. But, it does not seem so easy to update the two tables. I am not familar with sql. Are there any articles you would suggest? Re: What would be better?

You're going to have to learn SQL in order to do this, or any other database related project. I highly suggest picking up a book on SQL Server 2005 and going through it. The book might come with SQL Server 2005 Express Edition (free), or you can download it from Microsoft. If you write your query correctly, the DataAdapter object will fill a DataSet for you in as many DataTable and DataRelation objects as required.

So far I have my program working by sending the forms to the hastable in code. Like so... dim ptr as windows.forms.form ptr = new frmOne hashtable.add(ptr) what I would like to do is replace the code above with code that will dynamically populate the hashtable, something to the effect of... if projecttype\object\whatever is a system.windows.forms.form then hashtable.add(projecttype\object\whatever) I can't figure out how to do it I tried using reflection.assembly.getexecutingassembly however a forms BaseType is not always stated as system.windows.forms.form it can also be the project namespace.formname, which completely negates the whole purpose of using it.
