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.

 How to get datetime type of window system ? (ex:dd/MM/yyyy)
|
|
|
|
|
if you want to change the format you display on the screen then use
folloeong function
e.g you want to display te date in the textbox then
textbox.text=format(now.date,"DD/MM/yyyy")
In the same fashion you can use any format of the date.
|
|
|
|
|
No that mean.
I want to get window system datetime type, not format.
(e.g: dd/MM/yyyy or d/M/yy or, ...)

Those are date formats. Don't you want that?
There is only one DateTime type, it's System.DateTime and it's specified in the mscorlib.dll. It's the same for all systems, so there is no special DateTime type for any specific system.
If you want information about the current date format for the user, use CultureInfo.CurrentCulture.DateTimeFormat to get the DateTimeFormatInfo object that describes the date format.

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.
