Try:
listview1.Items.Insert(1, YourListViewItem)
(The index is 0-based)
Good luck,
Johan
My advice is free, and you may get what you paid for.

I'm creating a VB.net application ( vb.net 2005) .The application use a Ms access 2003 database with 5 fields ( Primary key is autonumber).I have create dataset using wizard.
I have problems when insert a new record in databse. The code is :
--------------
Dim drw1 As XTDataSet.PassRow
drw1 = Me.XTDataSet.Pass.NewPassRow
drw1("name") = "xxxxx"
drw1("ALG_1") = "ccccc"
drw1("aksnot") = True
drw1("aksfin") = False
Me.XTDataSet.Pass.AddPassRow(drw1)
Me.PassTableAdapter.Update(XTDataset.Pass)
Me.XtDataset.Pass.AcceptChanges()
-------------------------
With these code the new record is added to database , but after if i try to modify the new record ( without closing the form ) i get an error : Concurrency Violation....
If i close the form end reopen i can modify the new record without problems.
And without closing the form , if i fill again the dataset after adding new record everything is ok.
But how to do without closing the form and without filling again the dataset ( this is to slow)
Please help me !

Hi All
I want to print a wages slip for an employees through one of my project developed in VB6. The printing will happens using DMP i am using the following code: -
Dim Fn As String
Fn = FreeFile
Open Printer.Port For Output As #Fn
Print #Fn, "Some Text"; Tab(35); "Some Text"
Print #Fn, "Some Text"; Tab(35); "Some Text"
Print #Fn, "Some Text"; Tab(35); "Some Text"
Close (Fn)
This code print the slip but i want to reduce the text size, and want to change the font and paper size.
I use the printer.fontsize but its not working
Plz help me how could i do the same.
Thanks in advance

You're going to have to dig out the manual on the printer and find out what the codes are to tell the printer to change the font and styles. I think you'll find you are quite limited in what you can do.
Using the fontsize and other properties of the Printer object won't do you any good in this case. You're sending data directly to the printer port, not to the Spooler and you're not using any GDI objects to draw your printed image.

Well, it's doing wxactly what you're telling it to do. List ALL the rows that have a Name like "something%". You can look at the first row by getting index 0 of the Items collection.
Dim dv As New DataView(dttemp)
dv.RowFilter = "name LIKE 'text%'"
dv.sort = "name"
' Retrieve the first item in the sorted, filtered list:
Dim drv As DataRowView = dv.Item(0)
' Use the retrieved DataRowView as normal...

Hi there..
I want my application to check whether an input in a textbox is invalid when cmdAddDB is clicked.
It should check if there is a string for DByear value.
****************************************
DByear is declared as private integer
Sub CmdAddDBClick(sender As Object, e As System.EventArgs)
'check whether the textboxes are empty
If txtYear.text = "" OrElse txtMonth.text = "" OrElse txtDay.text = "" Then
'inform user of error
Messagebox.Show("Missing Information")
'clears all textboxes
txtYear.Text = ""
txtMonth.Text = ""
txtDay.Text = ""
Else
'set the textboxes to private variables & convert textboxes to
'integer values
DByear = CInt(txtYear.Text)
DBmonth = CInt(txtMonth.Text)
DBday = CInt(txtDay.Text)
End If
End Sub
****************************
Please can anyone help?
Thanx

Have you read the documentation for it? Have you even attempted to look up the documentation?

He just told you how to do it. Do you always ignore the answers you're given??
|

i've made a quick example for you, i think people forget they come on these boards to help people out when they start giving out sharp answers instead of just helping with a code snippet that only takes a moment to make.
Code:
<br />
<font face="Courier New" size="2"><font color="#008000"> '/// load original image from file as a Drawing.Image...</font><br />
<font color="#0000FF"> Dim</font> img <font color="#0000FF">As</font> Image = Image.FromFile("<a href="file:///C:/Image1.png">C:\Image1.png</a>")<br />
<font color="#008000"> ' <font color="#0000FF">Dim</font> g <font color="#0000FF">As</font> Graphics = Graphics.FromImage(img)<br />
<font color="#008000"> '/// draw the String on the image...</font><br />
g.DrawString("some text on an image!", <font color="#0000FF">New</font> Font(<font color="#0000FF">Me</font>.Font.Name, 16, FontStyle.Bold), <font color="#0000FF">New</font> SolidBrush(Color.Red), 10, 10, <font color="#0000FF">New</font> StringFormat(StringFormatFlags.DirectionVertical))<br />
<font color="#008000"> ' img.Save("C:\testing.jpg", Imaging.ImageFormat.Jpeg)<br />
<font color="#008000"> '/// clean up...</font><br />
g.Dispose()<br />
img.Dispose()<br />
<font color="#008000"> ' PictureBox1.SizeMode = PictureBoxSizeMode.StretchImage<br />
PictureBox1.Image = Image.FromFile("C:\testing.jpg")</font><br><br />
hope it helps  .
<font color="blue">Csharp</font> me = (<font color="blue">Csharp</font>)Dynamic_Sysop; <font color="#008000">// My Signature.</font><br><font color="#008000">$twins</font> = <font color="#008000">me.twins</font>(<font color="#800080">"Taylor"</font> , <font color="#800080">"Delta"</font>); <font color="#C0C0C0">// My twin daughters.</font><br>echo <font color="#008000">$twins</font>;

And what do I want with a code sample? I'm not the one looking to mark an image.
You missed the point of my post. He asked a question, got the description of how to do it, and then repeated his question, without saying anything about what he was having a problem with.
All to often, there are people who come here and just want the code written for them without having to lift a finger themselves to write it. That's why he didn't get code sample. He has to show that he at least attempted to solve the problem on his own. Then we'll go through and show him where he went wrong.

Maybe you didn't know this, but the only person who gets an email that you responded to a message is the person you are replying to. Everyone else in the chain does not get a notification that you posted anything. So, I'm the only who got a notification that you responded to my post.

erm, i wasn't giving a sample to your good self, i was aiming it at the person who asked for help. didn't realise it was a touchy subject to post code, sorry. i just presumed that it was ok to help people when they ask for help on a forum. the sample i posted was just a very basic guide to point them in a direction, not war in peace.
