Yes. VS2003 don't have any AJAX framework available. But you can do thi by writting XMLHttpRequest using javascript.

Sorry I don't have any idea on this. Instead of going for some third party programs, it's better to use your own script.
Magh_M wrote: Ok for this ajax we want ot install anything in our vs2003?,
For your information, AJAX is not only for .NET. It can be used with any web programming script. It's a concept where browser will give request to server asynchronously and avoids browser refresh. You can search for "using XMLHttpRequest in javascript" for getting started. Also check the browsers and versions that supports AJAX.

Ok, I have been searching for a while on this, and just cant work it out. I have web form with a INPUT type='file' called fileToAdd, and a textbox called tbTitle, and a button called btnUp.
The IDE is complaining about the line 'objStream.Read (bDocTemp, 0, iDocLength)', saying "'1-dimensional array of Byte' cannot be converted to '1-dimensional array of Char' because 'Byte' is not derived from 'Char'."
Fair enough, but I just cant figure out how to get it as a byte, all the examples I have found on the net for uploading images are the same as below, but it just wont work! If I DIM bDocTemp as a CHAR, the error goes away, but it wont work at run time.
Argghh! Any help will be appreciated please! Thanks
Protected Sub btnUp_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnUp.Click
Dim iDocLength As Integer = fileToAdd.PostedFile.ContentLength
Dim sExt As String = fileToAdd.PostedFile.FileName.ToString()
sExt = sExt.Substring(sExt.IndexOf(".", 0), 4)
Dim objConn As New SqlConnection("Data Source=XXXXX;Initial Catalog=XXXX;Persist Security Info=True;User ID=XXXXX;Password=XXXXX")
objConn.Open()
Dim objCmd As New SqlCommand("spUploadFile", objConn)
objCmd.CommandType = Data.CommandType.StoredProcedure
Dim pTitle As New SqlParameter
pTitle = objCmd.Parameters.Add("@Title", Data.SqlDbType.VarChar, 200)
pTitle.Direction = Data.ParameterDirection.Output
pTitle.Value = tbTitle.Text
Dim pType As New SqlParameter
pTitle = objCmd.Parameters.Add("@Type", Data.SqlDbType.VarChar, 3)
pType.Value = sExt.ToString
Dim bDocTemp(iDocLength - 1) As Byte
Dim objStream As StreamReader = New StreamReader(fileToAdd.PostedFile.InputStream)
objStream.Read (bDocTemp, 0, iDocLength) '<----Error here
Dim pDocument As New SqlParameter
pDocument = objCmd.Parameters.Add("@Document", Data.SqlDbType.Image)
pDocument.Value = bDocTemp
Dim pUser As New SqlParameter
pUser = objCmd.Parameters.Add("@user", Data.SqlDbType.VarChar, 50)
pUser.Value = Request.ServerVariables("AUTH_USER").ToString
objCmd.ExecuteNonQuery()
objConn.Close()
End Sub

Hi,
I made a simple report CrystalReport1.rpt which was added to my project (Add New Item => Crystal Report).
Now I want to use this report in my project, When i tried to write code in the code behind of the webform "CrystalReport1" code snippet did not appear. Then I typed the name of the report in the code:
CrystalReport1 = new CrystalReport1();
But I get this compile-error:
The type or namespace name 'CrystalReport1' could not be found (are you missing a using directive or an assembly reference?)
What is wrong?
Plz help.

Yes,
Add the foll. references to your project.
CrystalDecisions.CrystalReports.Engine<br />
CrystalDecisions.ReportSource<br />
CrystalDecisions.Shared<br />
CrystalDecisions.Web
and in your code behind file, import all the above references.
Hope this helps.

Yes I have added it in my code behind but its not working...
I kept like this...
using CrystalDecisions;
using CrystalDecisions.Shared;
using CrystalDecisions.ReportSource;
using CrystalDecisions.CrystalReports.Engine;
Plz Help.
Jagadeesh

OK.
Hope you also added reference ("Add Reference..") to your project. Check again
Harini
|
|
|
|

Just now I added it by right clicking on my project solution explorer and select "Add reference" and selected
* CrystalDecisions.CrystalReports.Engine.dll
* CrystalDecisions.ReportSource.dll
* CrystalDecisions.Shared.dll
and clicked ok.
In the code behind i added these classes.
Even now i am unable to get the Report name in the codebehind snippet.
Plz let me know your thoughts.

Can you tell me how can i confirm that these references were added to my project.
I couldn't see any difference even after adding these references. 
Jagadeesh
|
|
|
|

For an update, Just now I googled and found that We must get the "References node" after added the references.
But I am not getting it. 
Plz let me know how to get it.

Added references should appear in the project explorer under 'References'.
If not add again.

Harini,
I'm following these steps correctly.
When i binded a simple report using CrystalReportViewer control (with out using any dataset), It worked fine. (There is no code in the codebehind except the CrystalReportViewer bind property) It showed the values correctly.
When I tryed the same with the dataset in the code behind i am unable to get the reportname in the snippet.
CrystalReport1 crReportDocument = new CrystalReport1(); --> i'm not getting this report name here.
I am a fresher i don't know much about this. Is it compulsory to get the references node in the solution explorer to get the report name in the code behind.
Plz let me know your thoughts.

Response.AddHeader("content-disposition", "attachment;filename=RegisteredUsers.xls")
Response.ContentType = "application/vnd.ms-excel"
Response.Charset = ""
Me.EnableViewState = False
Dim oStringWriter As System.IO.StringWriter = New System.IO.StringWriter()
Dim oHtmlTextWriter As System.Web.UI.HtmlTextWriter = New System.Web.UI.HtmlTextWriter(oStringWriter)
oHtmlTextWriter.WriteLine("Registered Users: ")
'Me.ClearControls(dgGrid)
DataGrid1.RenderControl(oHtmlTextWriter)
Response.Write(oStringWriter.ToString())
Response.End()
