The easiest way would be to look for a web service to do this, but otherwise you will have to use some kind of screen scraping. Do a google search for screen scraping in asp.net and you should find plenty of articles.

If you do decide to use web services i have used

Hi
Just use File upload control that will upload the image that you want to update.
Regarding the file path FileUpload1.PostedFile.FileName will give you full path path of file from client machine
Google the subject you will find more articles on this topic

Thanks and Regards

this will help, you to upload image........
and Store the path in database

protected void Button2_Click(object sender, EventArgs e)

string sSavePath;
string sThumbExtension;
int intThumbWidth;
int intThumbHeight;

sSavePath = _Default.fullpath;

// Destroy objects

}

catch (ArgumentException errArgument)

lblOutput.Text = "The file wasn't a valid jpg file.";
System.IO.File.Delete(sSavePath + sFilename);
}

}
}
public bool ThumbnailCallback()
{

}

and read in this way

Assalam-0-Alaikum,
hru? well in .Net 2.0 there is a file upload control. put it on ur .aspx page. In code behind file
provide its id and press a dot(.). Now the real fun starts here.

--- to get file name :
dim fileName As String = FileUpload1.PostedFile.FileName
then u can use this string fileName to save it in the database using inLine Query or Stored Procedure etc. If u have Problem Inserting data in the database, do let me know. i would write u know how to do this.

-- to Save file in the specified Location:
FileUpload1.PostedFile.SaveAs("Location as string")

there are other properties and method for the fileupload control tht u could use but depend on the requirement.
Hope it Helps.

Assalam-0-alaikum,
yes i would tell u. look its u who will decide where to store the file. like,
fileupload1.postedfile.saveas("c:\myweb\images\image1.jpg")
now save the same path in the database i.e., c:\myweb\images\image1.jpg
now Question arises how to differentiate files. give them a unique name.
now how to give a unique name? there are so many ways but how do i save is, i create a folder with the username, save the file and name it with the username concatenated with some other patameters to make it unique.
hope u get it.

Hi phuhoa

In ASPX, variable not stored in a long time. Just whene the page is created. To use long life variable use session (however in default just 20 minuites).

Like the example:

First, store your variable
Session("textbox1") = textbox1.text

To retrieve it
textbox2.text = Session("textbox1")

Hope it is usefull for you.

Sandeep Akhare31-Oct-07 21:12

31-Oct-07 21:12

I am confused can you tell me What is Site A and Site B
If both are different web application then pass the value in query string if you don't know how to pass the query string please google it

Thanks and Regards

Hi Sandeep, Hi phuhoa

Query string is also a nice choice to "transfer" the variable. However, it is not really safe, when we deal with the security.

Let us follow the sample:

Me.TextBox1.Text = Request.QueryString.Get("prevpage").ToString

*Change the prevpage with the value of previous page.
