Hi Appu,

I assume you have saved the word doc in the SQL Server as a byte array...
and here is the code..
byte[] byteArray = //Get your byte array - ( file content )and assign it here.
string sFileName = //Get your fileName and assign it here
Response.AppendHeader("Content-Type", "application/msword");

Response.AddHeader("Content-Disposition", "attachment; filename=" + sFileName);
Response.BinaryWrite(byteArray);
Response.End();
Hope it works

Thx,
Gayani

DropDowns/GridView Column

Hello All,

Have a problem where I would like to display a column only if a particular item is selected in a drop down.

To be more specific, I display some values in a gridview and the last column contains a link that removes (actually just archives by setting a bit flag) the row from being displayed in the "Active" view. If the user wants to see "Archived" rows, they would select it from the DropDownList and the page automatically posts and displays the archived items. But the last column with the link still appears. In this view, the "Remove" link is useless and somewhat unprofessional looking.

What I need help with is NOT showing that column when the SelectedIndex of the DropDown is == 1. If it is == 0 then I want the last column to show as normal.

I have tried "GridView.Columns.RemoveAt" which works the first time but doesn't show again.

So, is there anyway to hide a column on a postback and make if visible again.

Thanks in advance for any suggestions.

Sorry for the quick posting. I got it to work by:

if (blah blah)
{
GridView1.Column[4].Visible = false
}
else
{
true
}

Thanks anyway gang. Take care

web.config authentication

This may seem like a very basic question but how to I get ASP.NET to authenticate based on the credentials provided in a .config file?

It's just for testing a site and when it's moved to production it will be in an SQL Database but whatever I do it tries to find an SQL database in ~/App_Data to load the authorization information from.

You probably have a sql-based membership provider configured in your web.config. Something like this:

<system.web>
  ...
  <membership defaultProvider="xxx">
    <providers>
      <add name="xxx" type="System.Web.Security.SqlMembershipProvider" ... />
    </providers>
  </membership>
  ...
  
</system.web>

You will probably want to change the <membership> configuration to a different provider for your test environment.

Nope, that's the thing which is annoying me, the web.config is blank from providers but I looked through the assemblies in the Object Browser and couldn't see anything to change it to.

Dim v As PROPREGLB.AssetQuerry '

End Function

}

when I debug retvalue,
I get retvalue as
__type "PROPREGLB.AssetQuerry, App_Code.hpedrzja, Version=1.0.5.31325, Culture=neutral, PublicKeyToken=null"

How to convert retval as the proper object of PROPREGLB.AssetQuerry

What kind of typecast has to be used.

I need to call methods available in
PROPREGLB.AssetQuerry class from the returned object in javascript also need to avail the existing data(inserted in the server side) in the javascript client side code.

any help will be highly apreciated.

Hi All,

I have System.Xml.XmlDocument xmldc = new System.Xml.XmlDocument(); I am able to load values in to it from XML String.
Now I want to read these values in to DataSet object or DataTable object. But without writing it in to the file. By writing in to the file I can but I dont want to use it.
If you want we can write it in to XMLReader objet, shouldnt write in to the file, which is time consuming.
Any help is very usefull.

Thanks a Lot,

The Controls collection cannot be modified because the control contains code blocks (i.e. <% … %>).

Hi there

I have a page with a DDL which binds the data in the .aspx page rather than the code behind. It was all working nicely until I moved this page onto another computer - it was working on one with Visual Web Developer Xpress but now it won't work on Visual Studio 2005. I thought maybe it is because the versions of .Net are different. I'm a newbie so please don't patronise!

Here is a snippet of my code:

<body>
<form id="form1" runat="server">
<div>
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:angell_eurosalesConnectionStringLocal %>"
SelectCommand="SELECT DISTINCT [BicCode], [Description], [BicCode] + ' : ' + [Description] AS CodeDesc
FROM [tblBicCode] WHERE LEN(LTRIM(BicCode))=1"></asp:SqlDataSource>

</div>

Please someone help me!

So you want the user to recieve the e-mail, then after they have recieved it you want to provide a prompt or cancel or save the document before they close the window?

Yes,
As per the functionality for downloading the document user must fill up a form containing his information. Once user fill and click on submit i m sending a mail to admin and downloading the document for user. When document get download Mozilla Firefox/internet explorer displays a prompt and ask user that he want to save document or just want to open. (like whenever we are downloading any file from server) once user done his action for document or after sending the mail i want to close that form (which is appearing in popup window).

Thanks

Thats because browsers render css differently.
A webiste designed for IE might not look correct in Firefox.
This is mainly down to the fact that IE almost corrects your mistakes in your css code where as firefox doesnt.
You will just have to go through it and change parts to suit both browsers

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
