fb.AccessToken = result.access_token
fb.Post("/me/feed", New With {Key .message = "My first post"})
But still no luck , anybody how can point me in the right direction , and please also include info how to get the access token.

HI,
Every one
As i am new in asp.net,so i don't know how to display data of multiple tables in single GridView.
Can any one help?
Thanks in ADVANCE...

It's unclear...
Do you want to display some unrelated data from several tables in one grid? I think it's impossible...
If it is complementary data from different tables use JOIN in the SQL...
If this is some hierarchical data you may see this article: http://msdn.microsoft.com/en-us/magazine/cc164077.aspx[^]
I'm not questioning your powers of observation; I'm merely remarking upon the paradox of asking a masked man who he is. (V)

Create a stored procedure and get the data from multiple tables as per their relation in one result set and display them in grid view.
|
|
|
|
|
If these two tables are similar, you can use a UNION[^] clause.
If they have a foreign key relationship, you could join[^] the two tables and then display them together.
Or
DataRelation dr = new DataRelation("Relation", ds.SomeTable.Columns["code"], ds.OtherTable.Columns["pCode"]);
gView.DataSource = ds.SomeTable;

To put it simply
A web page uses the HTTP Protocol to a web server to receive and send HTML
http://www.w3schools.com/tags/ref_httpmethods.asp[^]
So when you request a webpage, the HTTP protocol calls that
GET
When you fill out a form, you have to send the changed page back to the server, so that is called
POST
When using Page.IsPostback
You are saying, if the page is posting back to the server.
eg. POST
Submitting a form, a Button Click and the code that fires when the button clicks
A dropdown list item is selected.
Or you are saying, If the page is not posting back to the server.
eg. GET
The form is loading for the first time
Example:
When you create a form, you create the HTML such as empty textboxes.
In Page Load, you can populate the empty textboxes with values
So in Page Load
If Not Page.IsPostback then
End if

Did you build a class against it using xsd.exe.
I make XSD files, but I've never used them in any project. I use the xsd.exe and create a class file, and use that file for referencing the XML it represents.
How are you using it?

I am looking for creation of project templates. Most of our projects are in similar fashion. It includes ASP.Net 4.5 framework, Entity Framework 5.0, Custom Loggging Framework developed by us internally, and then CSS & Script files. What I wanted is that the User should be able to provide the project name like the one which is provided by Visual Studio New Project Templates. Once the user provided the project name, a new project will be created with all the above said dlls, script files, css files etc.
Is there any way which I can develop this custom template. I know that there is something called ASP.Net BoilerPlate. But that is in MVC, and I need in ASP.Net Web Forms.
Any article or URL will be greatly appreciated.

Visual Studio gives you the option to create your own templates from existing projects.

What's wrong with Session or QueryString? You can put something into a cookie or into application cache but session or query string are your best options.
There are only 10 types of people in the world, those who understand binary and those who don't.
|
|
|
|
|
You can use session if data is not that big or you can use cross page posting like PreviousPage.FindControl

Hello
I am trying to add style to a aspx (vb) file but I get an error:
http://www.bayingwolf.com/attributes.jpg[^]
That erroneous underlined line is:
messageArea = Attributes.Add("style", "display:block")
and it refers to this label in my aspx file:
<asp:label id="messageArea" CssClass="formattedText" runat="server">style='display:none;'></asp:Label>
What is the correct way of displaying the label, please?
The CssClass is this:
.formattedText
{
font: normal 14px 'Droid Sans' , 'Trebuchet MS' , Arial, sans-serif;
color: #ffffff;
position: absolute;
top: 330px;
border: 1px solid white;
padding: 15px;
}
Thanks for any help.

Try this:
messageArea.Attributes.Add("style", "display:block")
There is a typo of extra ">" inside;
runat="server">style='display:none;'

Hello Peter
Many thanks for that. Those errors have gone now.
Previously, if I clicked on the upload button without selected any file, I got this message:
"Your file " & Convert.ToString(uploadControl.PostedFile.FileName) & " can not be uploaded.<br>File types allowed: .doc, .docx, .txt, .png, .gif, .bmp, .jpg, or .jpeg.<br>"
Now, I don't get any message on screen. Likewise, if I select an .asp file which is not, strictly speaking, allowed, no message appears either.
I just wonder if the CSS and/or ASP label:
<<pre>asp:label id="messageArea" CssClass="formattedText" runat="server" style='display:none;'></asp:Label is preventing the message(s) from appearing?
Thanks again.
|
|
|
|
|
I can only say that
style='display:none;'
will cause the "messageArea" label not to be shown.
|
|
|
|
|
I have removed that and I can now see the relevant text when I deliberately commit an error (wrong file type or no file). A step forward, thanks!
The only remaining problem is that when I remove
style='display:none;'
and before I attempt to upload anything, I can see on the screen a small white empty box with nothing in it. That box should really only appear with the error text when I have committed an error.
