As you are creating an ASP.NET application so I would suggest you to use FileUpload control to upload the said file to your server’s working directory. Here is a small example which does that:
protected void UploadButton_Click(object sender, EventArgs e)
{
if(FileUploadControl.HasFile)
{
try
{
if(FileUploadControl.PostedFile.ContentType == "image/jpeg")
{
if(FileUploadControl.PostedFile.ContentLength < 102400)
{
string filename = Path.GetFileName(FileUploadControl.FileName);
FileUploadControl.SaveAs(Server.MapPath("~/") + filename);
StatusLabel.Text = "Upload status: File uploaded!";
}
else
StatusLabel.Text = "Upload status: The file has to be less than 100 kb!";
}
else
StatusLabel.Text = "Upload status: Only JPEG files are accepted!";
}
catch(Exception ex)
{
StatusLabel.Text = "Upload status: The file could not be uploaded. The following error occured: " + ex.Message;
}
}
}

I am using Sqlserver2005 and i took datatype image to store the uploaded file..
The document is storing in binary format in database...
Now,i want to retrieve the document in a Textbox which i am not able to do...
This is the code i used for fileuploading...
if (FileUpload1.FileName != "")
{
Stream ImageStream;
int intImageSize = FileUpload1.PostedFile.ContentLength;
byte[] ImageContent = new byte[intImageSize];
ImageStream = FileUpload1.PostedFile.InputStream;
int intStatus;
intStatus = ImageStream.Read(ImageContent, 0, intImageSize);
try
{ con.Open();
SqlCommand cmd = new SqlCommand();
cmd.Connection = con;
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "Image_table";
SqlParameter p = new SqlParameter();
p.ParameterName = "@Content";
p.SqlDbType = SqlDbType.Image;
p.Value = ImageContent;
cmd.Parameters.Add(p);
cmd.ExecuteNonQuery();
}

Hi Navaneeth,
Thanks for ur reply,
I already worked on what you had sent...
I am able to get the images but i need MS-Word Document...

For Eg:
when u visit naukri.com and click on register u will fill all the details and
upload resume...and when u want to update the resume, u will see it in a
textbox(multiline).
I am able to store the uploaded file in the database,but not able to retrieve
it from database and show the content in the textbox
If you have any ideas then plz send me.
Thank You,
Rajesh

So you need to show the contents to a text box ? Right. Try saving the file after reading from database to a temporary place. Then read it from there. Read contents to a byte array and save it using FileStream object. Then try reading file from that location. But still I am not sure that you can read a word file using StreamReader without loosing the formatting !

You just need to install the version of .NET framework along with VS version(to which you are looking to upgrade). Thereafter, you can migrate your earlier projects to the new version by some easy steps.
If this does not solve this issue, then please give a detail description of your requirements.

I have tried to connection SQL Server, but I always get the same error:
Error Type:
Microsoft OLE DB Provider for SQL Server (0x80004005)
[DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied.
/bhxhtth.com.vn/csdl/kndl_kocandns.asp, line 23
Here my code:
<%
dim oConn
dim oRS
dim strSource
set oCOnn=server.CreateObject("adodb.connection")
set ors=server.CreateObject("adodb.recordset")
strSource = "PROVIDER=SQLOLEDB;DATA SOURCE=10.0.0.1;DATABASE=MISBHXH;User Id=sa; Password=sa;Network Library=dbmssocn;"
oConn.ConnectionString = strSource
oConn.Open
sqltext = "Select MADVI, TEN from HOSOCN;"
ors.Open sqltext, oConn
Response.write ""
Response.Write ors.GetString(,-1," | "," | "," ")
Response.write " |
"
oRS.Close
Set oRS=nothing
oConn.close
Set oConn=nothing
%>
Please advise
Thanks.

try replacing DATABASE= in your connectionstring with INITIAL CATALOG=
|
|
|
|

I thank sqltext = "Select MADVI, TEN from HOSOCN;" is Error and the right is sqltext = "Select MADVI, TEN from HOSOCN"

Hey guys
Any idea about "Upload File via FTP using ASP.net 1.1"???
|
|
|
|
|
Use the Save AS.. method for file upload control to save youe file on to server then give the path for your server where you want to store the file.
|
|
|
|

FTP in ASP.NET 1.1 is a bit cumbersome process compared to .NET 2.0 where different new classes have been added. You may view following forum post which gives an idea on how to create your own FTP client in 1.1:
http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=421403&SiteID=1
Also note that in order to write an ASP.NET application that allows users to transfer files to and from FTP servers, the files must make two trips.
To upload files from a browser to the FTP Server would require:
1. The files to be located on the web server, because this is the FTP client. Therefore, the files must be uploaded to the web server from the browser. This is done using HTTP and not through FTP.
2. Once a file is on the web server, it can then be transferred to the FTP server using FTP communication.
The crux is, you have to use HTTP as well as FTP communication for the same

Hi Programmers,
In my application i m using 30 session varialbles.i want to know will it effect the application access speed,if the number of users are 5 how will it effect,if the number of users are many how it will effect.please suggest if this is not good then what is the solution for this.
waiting for reply
|
|
|
|
|
well using more and more session effects server speed. You can reduce number of sessions by passing information through querystring etc.
|
|
|
|
|
Definetly as session are going to store at server side the memory requirement for your application will increase if you use many session variables so if you have to store 3 to 5 varaibles then you can use session but 30 session varaibles sounds bad ...
Why are you storing those things in session ...... ?
Why don't you use database or pass them in query string if data is not concern to security ....
Or yuo can create xml files to store the data
Thanks and Regards

After repeated attempts, I have un-istalled IIS on the server and tried to Reinstall it again.The files on the installation cd seems to be corrupt because it cannot be copied across.As a result, the Exchange is no longer working due to the smtp service being removed.Is the some way to install IIS from an exe application or can these files be downloaded from somewhere?I Have tried to use the files from Windows server 2003 but it does not work.
Thanks

Why not to use Javascript Back button
<INPUT TYPE="BUTTON" VALUE="Go Back" <br />
ONCLICK="history.go(-1)">
|
|
|
|
|
you can write '' or on button click write 'Response.Redirect (Request.UrlReferrer.ToString());'

vcode column name doest not exist in your resulting Dataset.
YOUR SQL QEURY DOES NOT RETURN VCODE DATAFIELD NAME.
RUN YOUR SQL QUERY IN SQL QUERY ANALYSER AND CHECK OUT RESULT.

select * from table1,table2
