Thanks, im still getting build errors though:
Error 1 Cannot implicitly convert type 'System.Drawing.Image' to 'System.Drawing.Bitmap'. An explicit conversion exists (are you missing a cast?)
Bitmap source = Bitmap.FromFile(path + UploadImage.FileName);
Thanks

Bitmap source = (Bitmap)Bitmap.FromFile(path + UploadImage.FileName); try this
Does it will help you ?
Bitmap.FromFile(path + UploadImage.FileName);
return type is Image Why you want to convert it into Bitmap
What you want to do ?
Thanks and Regards

Ill give it a go, what i want to do is allow the user to upload a picture of themselves which is then resized automatically before it is saved. The image is just getting saved to file rather than in a database.
Thanks

J# is being discontinued. Therefore it will not exist soon. Learning a technology that is about to cease to exist is pointless.

This sounds just like the hundred or so other homework questions people post here daily.
Here's a tip - try it yourself. If you get stuck on any specific part feel free to come back and ask for specific help.

|
|
|
|

What specifically is it that you need help with? You have just posted your assignment, you don't expect anyone to do your homework, do you?

Hi,
I'd been looking around the net for a code that can delete rows in a data grid table but I just can't find any suitable ones.
What I need is that I can multiple delete it and with a message prompt before it delete all the selected one. It don't sound complicated but i just can't seems to get it done.
Would appreciate some help to open up my mind, thanks.

1.First create a template column for data grid
<asp:templatecolumn>
<itemtemplate>
<asp:linkbutton runat="server" id="lnkDelete" text="Delete" onclientclick="return confirm('Are you sure?')" commandname="Delrecd" commandargument="<%# Eval("ProductID")%>">
2.set an event in DataGrid as
OnItemCommand="mydatagrid_ItemCommand"
3.Now in the code behing file in mydatagrid_ItemCommand function
protected void mydatagrid_ItemCommand(object source, DataGridCommandEventArgs e)
{
if (e.CommandName.ToString() == "Delrecd")
{
SqlConnection con = new SqlConnection("connstring");
con.Open();
int pid = Convert.ToInt32(e.Item.Cells[0].Text);
String updtstr = "Delete from products where ProductID=" + pid;
SqlCommand cmd = new SqlCommand(updtstr, con);
cmd.ExecuteNonQuery();
con.Close();
mydatagrid.EditItemIndex = -1;
binddatagrid(); //this method bind data in datagrid
}
}
just follow this u will get what u want bye

Hi Piyush,
Thanks, but at later checking, I was wondering is there a different between data grid and data view as it seems mine is data view, that whether the code used is the same.

How to update a gridview if we have used sqldatasource and updatecommand is storedprocedure,How We can get the edited fields of gridview as a parameters for our stored procedure used here??????

Use the SqlDataSource for this or code it your self.
I asume you will not use the SqlDataSource.
Steps:
1) fetch the GridViewRowUpdate event
2) compare old and new value
3) create sql statements
See sample(you should call your Storedproc with SqlCommand class)
Protected Sub GridViewDetectorInstellingen_RowUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewUpdateEventArgs) Handles GridViewDetectorInstellingen.RowUpdating
Dim newvals As IOrderedDictionary = e.NewValues
Dim oldvals As IOrderedDictionary = e.OldValues
'note TDBP1 is column name in Grid
Dim begin As String = newvals.Item("TDBP1").ToString()
Dim einde As String = newvals.Item("TDBP2").ToString()
Dim oudbegin As String = oldvals.Item("TDBP1").ToString()
Dim oudeinde As String = oldvals.Item("TDBP2").ToString()
Dim keys As IOrderedDictionary = e.Keys
'Keys are the key columns from the main key of the source table
Dim dim1 As String = keys.Item("Dimension1")
Dim dim2 As String = keys.Item("Dimension2")
Dim kid As String = keys.Item("KID")
Dim sql As String
Dim pos As Int32
If Not IsNothing(begin) Then
If begin <> oudbegin Then
pos = begin.IndexOf(":")
If pos > -1 Then
begin = begin.Remove(begin.IndexOf(":"), 1)
End If
sql = "update Elementen0 set [Value] = " & begin & " where Dimension1 = " & dim1 & " and Dimension2 = " & dim2 & " and OID = (select ID from Objecten where KID = " & kid & " and Naam = 'TDBP1')"
globalstuff.ExecuteNonQuery(sql)
End If
End If
If Not IsNothing(einde) Then
If einde <> oudeinde Then
pos = einde.IndexOf(":")
If pos > -1 Then
einde = einde.Remove(einde.IndexOf(":"), 1)
End If
sql = "update Elementen0 set [Value] = " & einde & " where Dimension1 = " & dim1 & " and Dimension2 = " & dim2 & " and OID = (select ID from Objecten where KID = " & kid & " and Naam = 'TDBP2')"
globalstuff.ExecuteNonQuery(sql)
End If
End If
'no update through SqlDataSource permitted
e.Cancel = True
'update is done through code behind so stop editmode
Me.GridViewDetectorInstellingen.EditIndex = -1
Me.GridViewDetectorInstellingen.DataBind()
End Sub
