ADO.NET :: How To Get And Write Data To A DB Located On The Server
Jan 2, 2011
I have a silverlight client that i want to get and write data to a DB located on the server . now this is what i did :
1. created the silverlight projecte hosted in asp site project, with wcf enabled .
2. created a DB with some tables in it.
3. created linq to sql classes, and wcf service with operation to fetch data from the DB, added the project the referance .
result:
when i debug it locally on localhost, it workes perfectly, but when i upload all the content to the server i get an error, my guess is that the service is not finding the DB . after I uploaded the content, all i did was change the connection string in my web.config file to the one provided to me by the hosting server.
exception:

I am trying to post data from vb.net application to web service asmx that is located on server! For posting data from vb.net application I am using this code:
Public Function Post(ByVal url As String, ByVal data As String) As String
Dim vystup As String = Nothing
Try
'Our postvars
Dim buffer As Byte() = Encoding.ASCII.GetBytes(data)
'Initialisation, we use localhost, change if appliable
Dim WebReq As HttpWebRequest = DirectCast(WebRequest.Create(url), HttpWebRequest)
'Our method is post, otherwise the buffer (postvars) would be useless
WebReq.Method = "POST"
'We use form contentType, for the postvars.
WebReq.ContentType = "application/x-www-form-urlencoded"
'The length of the buffer (postvars) is used as contentlength.
WebReq.ContentLength = buffer.Length
'We open a stream for writing the postvars
Dim PostData As Stream = WebReq.GetRequestStream()
'Now we write, and afterwards, we close. Closing is always important!
PostData.Write(buffer, 0, buffer.Length)
PostData.Close()
'Get the response handle, we have no true response yet!
Dim WebResp As HttpWebResponse = DirectCast(WebReq.GetResponse(), HttpWebResponse)
'Let's show some information about the response
Console.WriteLine(WebResp.StatusCode)
Console.WriteLine(WebResp.Server)
'Now, we read the response (the string), and output it.
Dim Answer As Stream = WebResp.GetResponseStream()
Dim _Answer As New StreamReader(Answer)
'Congratulations, you just requested your first POST page, you
'can now start logging into most login forms, with your application
'Or other examples.
vystup = _Answer.ReadToEnd()
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try
Return vystup.Trim() & vbLf
End Function

Is there anything missing in IIS 6.0 that prevents me from (Insert into table) using MS-Access?
Explain: The application works fine under Visual Studio 2008 IDE the insert into table works fine with no error, Also I tested with hosting provider and works fine with no problem. but now I have published the same exact app in a dedicated server windows 2003 with
IIS 6.0 .NET framework 2.0 with latest service pack I gave IIS_WPG write/modify access to the folder where MS-Access database is located and database but at the time of insert an error pop-up. I need to install in the Server or settings in the IIS to recognize my MS-Access db is it some office runtime that I am missing. (BTW I am using OLEDB connection string in my C# )
Using System.Data.OleDb;
I can retrieve data off of it with no problem but when I try to insert is when it fails I thought the problem was Access Rights but I do not think is the case.

I've got a ASP.NET site that's located on a local server (MY_SERVER). And one of the things it does is pull up tiff files which are located on another server (ANOTHER_SERVER). The location of each of these files is stored in SQL. I pull up each of these images and am supposed to display them. The problem is:
the files are not named with a tiff extension (does it matter?) they aren't displaying at all.
I am using an Image control to display these images, and I'm not sure if it matters that the extension is not set (does the image control know the difference between an jpg and a tiff without the extension?)
I am guessing the images aren't displaying because they are not on the same server MY_SERVER that the images are located (ANOTHER_SERVER).
edit: actually displaying the tiff files were amazingly simple:
protected void Page_Load(object sender, EventArgs e)
Response.ContentType = "image/png";
new Bitmap(Request.QueryString["ImagePath"]).Save(Response.OutputStream, ImageFormat.Gif);
}
but because the images are located on ANOTHER_SERVER I still can't access them. I may just do a hack where I copy them to a local directory on MY_SERVER but there's gotta be a simple way to fix this. Anyone?

I want to grant access to some ressources located on server only for specified web pages, how could I do this?
For example I have an image www.mysite.com/images/image.jpg and something like <img src="www.mysite.com/images/image.jpg" /> should only work on site asp.net.
Is it possible with web.config or maybe with some C# code?

I'm working on an ecommerce project that is missing 5,000 product pictures.
I am trying to assign all products without pictures into a category located on a mapping table.
I know an insert can be accomplished from one table (or subquery) to another but I only need to find the product IDs and insert them with default values into the category mapping table that has all non-null columns.
The following code is the farthest I can get without help (I'm not strong in SQL), it won't work because my subquery returns many rows while the SQL statement is designed to insert one - I don't know how to handle this...
[Code]....
Any help would be appreciated from those more experienced than I. BTW... there are no known search results for this type of solution - if there is even a solution.

Suppose we want to select the data from the database then we write the query for that. Example:
SqlConnection con=new SqlConnection(Connetion name) string selectPkId = @"SELECT PK_ID FROM TABLE" SqlCommand cmd=new SqlCommand(selectPkId ,con);
So,my question is that why we basically use @ before the sql query.If I don't use @ before that then it again work fine (does not give any error), then what is need of using "@"?

I have a gridview which displays thumbnails in the first column and details in the other columns. The thumbnail URL is being retrieved using the following:
[Code]....
However, if the thumbnail cannot be located, a white box with a cross appears instead (as expected).
To handle this better, I would like to display a different image if the thumbnail cannot be located for any reason, for example an image saying "Image Cannot Be Displayed". But I am unsure of how to do this, of even where to do this. Essentially I need to assess the value that the datagrid is using for the particular URL when it is databound. But can I put VB.NET code in this?
