<asp:textbox id="txttrgtprd" runat="server" font-size="X-Small" onfocus="getdata(this)" ontextchanged="txttrgtprd_TextChanged" backcolor="#ffffcc" width="70px" text="<%# Eval("TRGT_PRD") %>" autopostback="true" xmlns:asp="#unknown"></asp:textbox>
function getdata(obj)
{
var txt = document.getElementById(obj);
txt.value='0';
}
note in the above snippet that you are passing a reference to the textbox (this) to the javascript method, hence you dont need the getElementById at all - you already have a reference to the element.
therefore, your javascript method can simply be
function getdata(obj)
{
obj.value='0';
}
or your textbox's onfocus could simply be:
onfocus="this.value='0';"

|
Please give more info about what you are trying to achieve, as often you dont even need the ID of the textbox. If you do, a textbox has a UniqueID property which you can use from Javascript

The following code done in c# coding side.
string conn = ConfigurationSettings.AppSettings["connstring_card"];
con = new OleDbConnection(conn);
con.Open();
com = new OleDbCommand("select CardInfo1 from Card where State=1", con);

The guy you 1 voted had it right. If you were to use google, you'd get heaps of info on this. Seeing as you're too lazy, I did it for you. Here's the answer I found.
"that usually indicates that the default sort order in Pdox and Access are different, and the Pdox table you're trying to touch is keyed (indexed)"
Imagine how much work you could achieve if you were willing to search for yourself ?

Hey Dude,
Declare the oledb Connection Object Like This.
OleDbConnection cn=new OleDbConnection(ConfigurationManager.ConnectionStrings["connstring_card"].ConnectionString;
may be it will helpful to you...

1) He's clearly not defined his conn string in the ConnectionStrings element in his web config - he's defined it in appSettings
2) Your code snippet would not compile, it's missing a closing parenthesis.

Hi there,
I'm having a pretty serious problem with file uploads not working on my live site. I was able to upload fine when I was testing in VS on my local machine.
When I try to upload a file I'm getting the following error:
Server Error in '/' Application.
--------------------------------------------------------------------------------
Could not find a part of the path 'C:\Users\Fred\Desktop\James\Organised Files\Images\cherries.jpg'.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.IO.DirectoryNotFoundException: Could not find a part of the path 'C:\Users\Fred\Desktop\James\Organised Files\Images\cherries.jpg'.
I'm using an aspnet fileupload control and my code is as following:
Dim photoFileUpload As FileUpload = CType(dvCrops.FindControl("photoFileUpload"), FileUpload)
If photoFileUpload.PostedFile Is Nothing Then
lblMessage.Text = "No file specified."
Exit Sub
Else
Dim FileName As String = photoFileUpload.PostedFile.FileName
All my following code requires FileName to be accurate. So i'm 100% sure my problem is on that last line.
I've tried using System.IO.Path.GetFullPath but that doesn't seem to be helping.
Any ideas would be really helpful.
Many Thanks

The path here refer to the client machine path. It doesn't matter. Where you are trying to upload? I meant the server's location at which the uploaded files are stored.

I'm actually uploading an image file directly onto a database. I can edit that database so I have appropriate access. It's just an image file from my local computer. I'm sure i've just missed out something to tell the server to look on the users computer.

R u storing only Image full path in database or complete file??????
Because if u r storing only path, then while u retrive server reads pathe as C://.......... and tries to find that file in server's C://, and file is obviously not their. .. so its giving FileNotFound Exception I guess....
Tell me what u r doing???

Definitely you are missing something. Post your uploading code. Will try to find out the problem.

Essentially I'm Identifing the file, loading and resizing it in memory and producing a System.Data.Linq.Binary object that is uploaded to my database.
All this works when I'm running the website on my local machine. The live version can't find the file.
Here Goes:
'----------------------------------------------------------------------------------
' Name : btnAddPhoto_Click
' Purpose : This event handles the Conversion of the uploaded image files to System Data Linq Binary.
'----------------------------------------------------------------------------------
Protected Sub btnAddPhoto_Click(ByVal sender As Object, ByVal e As System.EventArgs) 'Handles btnAddPhoto.Click
Dim photoFileUpload As FileUpload = CType(dvCrops.FindControl("photoFileUpload"), FileUpload)
If photoFileUpload.PostedFile Is Nothing Then
lblMessage.Text = "No file specified."
Exit Sub
Else
Dim FileName As String = photoFileUpload.PostedFile.FileName
Dim ext As String = FileName.Substring(FileName.LastIndexOf("."))
ext = ext.ToLower
If ext = ".jpg" Then
ElseIf ext = ".bmp" Then
ElseIf ext = ".gif" Then
ElseIf ext = "jpg" Then
ElseIf ext = "bmp" Then
ElseIf ext = "gif" Then
Else
lblMessage.Text = "Only gif, bmp, or jpg format files supported."
Exit Sub
End If
' convert the fileupload.postedfile to system.data.linq.binary
Dim source As FileInfo = New FileInfo(FileName)
Dim buffer() As Byte = New Byte(photoFileUpload.PostedFile.ContentLength - 1) {}
source.OpenRead.Read(buffer, 0, photoFileUpload.PostedFile.ContentLength)
buffer = ResizeImageFile(buffer, 200)
crpImage1 = New System.Data.Linq.Binary(buffer)
lblMessage.Text = "Image Successfully Uploaded."
End If
End Sub
ResizeImageFile refers to this:
Public Shared Function ResizeImageFile(ByVal imageFile() As Byte, ByVal targetSize As Integer) As Byte()
Using oldImage As System.Drawing.Image = System.Drawing.Image.FromStream(New MemoryStream(imageFile))
Dim newSize As Size = CalculateDimensions(oldImage.Size, targetSize)
Using newImage As Bitmap = New Bitmap(newSize.Width, newSize.Height, PixelFormat.Format24bppRgb)
Using canvas As Graphics = Graphics.FromImage(newImage)
canvas.SmoothingMode = SmoothingMode.AntiAlias
canvas.InterpolationMode = InterpolationMode.HighQualityBicubic
canvas.PixelOffsetMode = PixelOffsetMode.HighQuality
canvas.DrawImage(oldImage, New Rectangle(New Point(0, 0), newSize))
Dim m As New MemoryStream
newImage.Save(m, ImageFormat.Jpeg)
Return m.GetBuffer
End Using
End Using
End Using
End Function
Calculate Dimensions to this:
Public Shared Function CalculateDimensions(ByVal oldSize As Size, ByVal targetSize As Integer) As Size
Dim newSize As Size
If (oldSize.Height > oldSize.Width) Then
newSize.Width = CType((oldSize.Width * CType((targetSize / CType(oldSize.Height, Single)), Single)), Integer)
newSize.Height = targetSize
Else
newSize.Width = targetSize
newSize.Height = CType((oldSize.Height * CType((targetSize / CType(oldSize.Width, Single)), Single)), Integer)
End If
Return newSize
End Function
Hope this clears everything up.
Thanks in advance!
