VS 2008 has built in support for ajax which was not present in VS 2005 that is why you are facing this error.

in your Project you have referenced an Assembly with this Version 1.0.61025.0 and you opened your Project VS 2008 and Automatically it added 3.5.0.0 now you need to use one. Remove the old one that targets 2.0 <b>1.0.61025.0</b> and leave the 3.5 one. remove it in the webconfig.

Hi! I have the next problem: I have a master page which has a textbox and a Web Content Form which is built from my master page. In the Web Content Form I have a button and I when I press it, I want the text from the textbox to update. For example when I view in browser my Web content form when I press my button, the text from the textbox should look like "You've press a button". Can anyone help me? Thanks!

You can access the textbox by accessing the master page object.

A simple Google search for "access master page controls from content page"[^] would get you these

Hi frnds,

I hv a code to get width and height of image in a file. Image is stored in folder and imagename in database.. I'm using asp.net 2.0 and sqlserver 2005.

Dim width,Height as integer
ImgPath = "~/Photos/" & ImgName
Dim fullSizeImg As System.Drawing.Image = System.Drawing.Image.FromFile(ImgPath)
width = fullSizeImg.Width
Height = fullSizeImg.Height

This works only in localhost. But after uploading to server it is not working. Is ther any other method to get the width and height of the image from server..?

The most common problem when something "works locally, but not on the server", is because the path that you are expecting your images to be in either doesn't exist on the server, or you don't have permissions to access it.

Check those first, then get back to us with more details about the error that you are getting.

Okay, so assuming they exist (and the file also exists), what is the actual error you are receiving?

Sir, This is the error i'm getting..

i think it is giving error for FromFile(str). Whether FromFile() is used only to get path from localhost ?

fileinfo object can't find file path

I have a app that when ran locally will upload my file to the database but if I try remotely it can't find the file. I am using the fileupload control and streaming it to the database. Is there a permission setting I am missing? This is called from the button_click of a submit button

byte[] ReadFile(string sPath)
{

byte[] data = null;

FileInfo fInfo = new FileInfo(sPath);----THIS IS WHERE IT CANT FIND sPath
long numBytes = fInfo.Length;

FileStream fStream = new FileStream(sPath, FileMode.Open, FileAccess.Read);

BinaryReader br = new BinaryReader(fStream);

data = br.ReadBytes((int)numBytes);
return data;
}

Check the value in the sPath if it actually exists on the server.
If sPath is the path that FileUpload control has provided, it will obviously not work. Since it is the path of the file on the client computer and this code runs on server.

Well my solution was I created a folder for the upload control to upload to then my sp would go grab the file for the folder on the server and insert into the table. This worked.

Adobe Reader couldn't open "invoice__2009[1].pdf because it is either not supported file type or because the file has been damaged(for example it was sent as an email attachment and wasn't correctly decoded)

Response.TransmitFile(Server.MapPath(("~/") + "Shopping/pdfInvoice/" + inv));

Check the response. I think you are ending the response before writing the output.

Also use Response.BinaryWrite to write binary data in response.
