Hi,
need help with the following code, the intention is for my server-side web app to open a doc held on the server's drive using a clients external native program (ie. notepad for a .text doc).
my code so far:
(previous page redirects to here after setting the file path as the session 'FullFilePath')
FileStream theFile = File.Open(Session["FullFilePath"].ToString(), FileMode.Open);
Response.AppendHeader("content-disposition", "attachment;filename="+Session["FullFilePath"].ToString());
Response.Write(Session["FullFilePath"].ToString());
long filesize = theFile.Length;
byte[] getContent = new byte[filesize];
Response.BinaryWrite(getContent);
Response.Flush();
Response.Close();
theFile.Close();
theFile.Dispose();
compiled my site which was all fine
but then get server error in my app when i browse to it after its set live.
'Specified argument was out of the range of valid values.
Paramater name: offset'?
but I can't see that anythings wrong?
any thoughts at all?

What line does the code on. The other response.write of the filename might also be giving you a problem...
|
|
|
|
|
it seems to be on the filestream line, which made me think that the file path was bad, but then i response.write displays the path as ok, though the system may think otherwise
|
|
|
|
|
ok, with lots of playing I've narrowed it down to the
'Response.BinaryWrite(getContent);'
It took me a while to get that bit to what I thought was right, and taking it out lets the page work, but it just tries to open a new IE window with the redirected page in it rather than the file that I'm trying to open, I'm a little stumped as this is al new to me.

HI all,
I need a help for printing the content of the page displayed in the webpage
using vb.net
Can anybody help
I will be very very pleased if i get answer

Printing on the client? You can just get them to hit the print button in the browser...
Also, you can set css styles with a media of 'print' that will control how your page is displaying the print preview.

I hope the following article may help u out
Ever wanted to print a DataGrid alone from an ASP.NET Web page? Put an <asp:DataGrid> tag inside the tag does the trick. Here are the steps involved:
1. Enclose the <asp:datagrid></asp:datagrid> tag inside the <div></div> tag.
2. Write a JavaScript function which takes care of printing the content from <div> tag.
Here's an example:
<script language=javascript>
function CallPrint(strid)
{
var prtContent = document.getElementById(strid);
var WinPrint = window.open('','','letf=0,top=0,width=1,height=1,toolbar=0,scrollbars=0,status=0');
WinPrint.document.write(prtContent.innerHTML);
WinPrint.document.close();
WinPrint.focus();
WinPrint.print();
WinPrint.close();
prtContent.innerHTML=strOldOne;
}
</script>
<div id="divPrint">
<asp:datagrid>
.....
.....
.....
</asp:datagrid>
</div>
<asp:button ID="btnPrint" onClick="javascript:CallPrint('divPrint');" Runat=Server />
Everything Is Possible!

I have a webform whereby i use a dropdown list to select fields like title,province etc. but the problem is that when i select a value from the dropdown and click save button,the field in the database becomes blank.
my code is as follows:
BUSINESS LAYER
Public Function GetTitle() As Data.DataSet
Dim strSQL As String
Dim obj As Datalayer.Database = New Datalayer.Database
'strSQL = "Select * from UserProfile with (nolock) where UserName='" & strUserName & "' and Status = 'A'"
strSQL = "Select TitleID, Title from Title1 with (nolock) "
GetTitle = obj.GetDataSet(strSQL)
obj.Close()
Exit Function
End Function
PRESENTATION LAYER
Private Sub LoadTitle()
Dim ds As New Data.DataSet
Dim objdata As Businesslayer.Contractors = New Businesslayer.Contractors
ds = objdata.GetTitle
cbotitle.DataSource = ds
cbotitle.DataBind()
cbotitle.Items.Add(New ListItem("Select...", ""))
cbotitle.Items.Item(cbotitle.Items.Count - 1).Selected = True
End Sub
BUTTON SAVE
Dim obj As Businesslayer.Contractors = New Businesslayer.Contractors
Dim ds As Data.DataSet
ds = obj.Getcontractor(txtfirstname.Text)
obj.AddContractor(txtID.Text, cbotitle.SelectedItem.Value, cbogender.SelectedItem.Value, txtfirstname.Text, txtlastname.Text, _
txtIDNumber.Text, txttel.Text, txtcell.Text, txtfax.Text, txtemail.Text, _
cbodepartment.SelectedItem.Value, txtlocation.Text, txtcity.Text, txtpostal.Text, txtoccupation.Text, cbomtype.SelectedItem.Value, _

the field in the database becomes blank.?
you mean. the selected value doesn't store in database.
some tips.
1. Set the breakpost in Button Save. Check the selected value of combobox.
2. Check whether you got any value (eg: paraProvince) in Businesslayer.Contractors.AddContractor() function. [Make ensure that all values of parameters has been passed from Presentation Layer to BusinessLayer.]
3. Check the SQL Statement.. [Make ensure that all values of parameters has been passed from BusinessLayer to DataLayer.]

Hi,
1. If you are adding any .aspx, that file should be a valid .aspx file. i.e Page should have '<% @Page Language='C#' %>. Otherwise it will not display.
2. If the page is valid then you need to set default page.
Open Inetmgr -> Right Click your web application -> Go to second tab 'Documents' -> Remove all files from the list -> And add your default page name.
3. If application files are in main folder (i.e wwwroot/inetpub) .. then it can be accessed using the link 'http://localhost.
4. If in some other folder then 'http://<virtual directory> (make sure that you have added default document as given in step 2).
Hope this helps.

Check and make sure that C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_isapi.dll is assigned to the Aspx extention in you application mapping dialog. You may have not installed .NET

in the databound gridview i want a hyperlink . on click of which it should go to another form carrying a querystring.
urgent !!
thanks in advance
|
|
|
|
|
To accomplish this you need to override the Gridview OnItemDatabound.
Then find your Hyperlink control and set his NavigateURL to your desired databound field from the parameter “e”.
Can you tell us what you have done or accomplished. This will help us to determine what particular problem/mistake you have.

Mark

Or your can use a HyperLinkField and have the grid view do it all for you

Hello all,
I am new to .net, m developing a small application, the problem i face is whenever there is a postback on my page the font size of the whole page increases. How can i avoid this ??

Strange !!!  Never Seen
Have you writen any code in Post back ?
<l>Thanks and Regards

Hi Deepak,
If font size increases after postback, it means there is some javascript error.
If it so, but how to check?? Then double click on the left corner of your web browser. (Instead of text 'Done', text 'Done with some errors' will be displayed if there is an error in your .aspx). Error may be syntax error or Braces not enclosed etc...
Check it now. Hope you got it.

May be the possible cause of this problem is you have improper html tags, I mean no closing tags.
How will this happen.
1.You have a literal control then you set his value to this Literal1.Text =”<H1>My H1” when page load was trigger.
2.You have a label and you set his value to this Labe1.Text = “This is a <B>Bold”.
3.GridView or Datagrid Item has a HTML value with no closing Tags.
4.You have generated a DHTML code with no closing Tags. Eg. InnertHTML or OuterHTML.
I think there are much more reason out there.
Check your browser view code now to verify if your HTML conform to HTML standards or XHTML.
Regards,
Mark
