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.

Sir, Thank you for reply..
There is permission for folder and path is also exist.
|
|
|
|
|
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..
Security Exception
Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.
Exception Details: System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
Source Error:
Line 42:
Line 43: Public Sub CheckWH()
Line 44: Dim fullSizeImg As System.Drawing.Image = System.Drawing.Image.FromFile(str)
Line 45:
Line 46:
Source File: D:\Hosting\5201676\html\Gallery.aspx.vb Line: 44
i think it is giving error for FromFile(str). Whether FromFile() is used only to get path from localhost ?
Plse reply..

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.

Correct its the path of the client computer. So how do I fix it?
|
|
|
|
|
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.

I have Created a pdf file by using pdfSharp and save in a location.but when i want to open that pdf file on the link button click event down load dialogue box is appear and when i clicked the open button.Adobe Reader throws the Strange Error message.the Error Message is
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)
(my filename is only invoice__2009 but [1] is extra comming in the message)
can you help me for this matter?
My code sample is
string inv = Session["invN0"].ToString();
Response.Clear();
Response.ClearHeaders();
Response.ContentType = "application/pdf";
Response.AppendHeader("Content-Disposition", "attachment; filename=" + inv);
Response.TransmitFile(Server.MapPath(("~/") + "Shopping/pdfInvoice/" + inv));
Response.End();
Thank You

Check the response. I think you are ending the response before writing the output.
Also use Response.BinaryWrite to write binary data in response.
|
|
|
|

I also tried that but the result is same.
This code works when I used it on same Block where i generate the pdf.But when i pass the Pdf file name in session and used it in the Button click event this error throws.

If you want only one item to be selected, use radio buttons. Not check box.

if i want to do it using checkbox what shud i do.can i do this without using script.
|
|

Just put one Javascript which might uncheck all other checkboxes whenever one checkbox is checked.
var thiselement = null;
var elem = document.getElementsByName('groupname');
for(var i=0; i<=elem.length; i++){
if(!elem[i].id.equals('checkboxclientid')
elem[i].checked = false;
else
thiselement = elem[i];
}
thiselement.checked = true;
Just pass appropriate groupname and checkboxclientid and you are done.
