User-940083561 posted
Hi, all.
Attached is showing how the 3 parameters are passed to ahsx asp.net. But in the ashx, it would use something like as below :http://172.20.100.12:888/rpt_Detail_dept.ashx?cardno=0000008904&year=2018&month=2
This is to select all the record based on month.
Now my requirement is to change to cardno=0000055799&txtLog_Date='2/2/2018'&txtCompleted_Date='2/3/2018'can somebody help to revise below ashx coding so that it can pass correct parameter to my store procedure in MSsql..
<%@ WebHandler Language="VB" Class="rpt_Detail_Dept" %>
Imports Microsoft.Reporting.WebForms
Public Class rpt_Detail_Dept : Implements IHttpHandler, IRequiresSessionState
Private dConn As New SqlConnection(ConfigurationManager.ConnectionStrings("DataDB").ConnectionString)Public Sub ProcessRequest(Page As HttpContext) Implements IHttpHandler.ProcessRequest
Try
Dim dComm As New SqlCommand("", dConn), tData As New DataTable()dComm.CommandText = "[$_RptDetail]"
dComm.CommandType = CommandType.StoredProcedure
dComm.Parameters.Add(New SqlParameter("@Card", CardNo(Page)))
dComm.Parameters.Add(New SqlParameter("@Mnth", Month(Page)))
dComm.Parameters.Add(New SqlParameter("@Year", Year(Page)))
dComm.CommandTimeout = 0Dim dData As New SqlDataAdapter(dComm) : dData.Fill(tData) : dData.Dispose() : dComm.Dispose()
Dim iStrm As String() = Nothing, iWarn As Warning() = Nothing, iEncd As String = "", iExtn As String = "", iMime As String = ""
Dim iRepo As New LocalReport(), iData As New ReportDataSource()iData.Name = "tMain" : iData.Value = tData
iRepo.ReportPath = Page.Server.MapPath("~/rpt_Detail_Dept.rdlc")
iRepo.DataSources.Add(iData)Dim iByte As Byte() = iRepo.Render("PDF", Nothing, iMime, iEncd, iExtn, iStrm, iWarn)
Page.Response.Buffer = True
Page.Response.Clear() : Page.Response.ContentType = iMime
Page.Response.AppendHeader("content-disposition", "attachment; filename=" & Now.ToString("yyyyMMdd_HHmmss") & "." & iExtn)
Page.Response.OutputStream.Write(iByte, 0, iByte.Length)
Page.Response.Flush()
Catch ex As Exception
Page.Response.ContentType = "text/html" : Throw ex
Finally
If Not dConn.State = ConnectionState.Closed Then dConn.Close()
End Try
End SubPublic ReadOnly Property IsReusable() As Boolean Implements IHttpHandler.IsReusable
Get
Return False
End Get
End PropertyPublic ReadOnly Property CardNo(Page As HttpContext) As String
Get
Dim iData As StringIf Not String.IsNullOrWhiteSpace(Page.Request.QueryString("cardno")) Then
iData = Page.Request.QueryString("cardno")
Else
iData = ""
End IfReturn iData
End Get
End PropertyPublic ReadOnly Property Month(Page As HttpContext) As Int32
Get
Dim iData As Int32If Not Double.TryParse(Page.Request.QueryString("month"), iData) Then iData = Now.Month
Return iData
End Get
End PropertyPublic ReadOnly Property Year(Page As HttpContext) As Int32
Get
Dim iData As Int32If Not Double.TryParse(Page.Request.QueryString("year"), iData) Then iData = Now.Year
Return iData
End Get
End PropertyEnd Class
--------------------------- end of ashx ------------------------------------------------------------
Above ashx will pass the parameter to sp as below :set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
GO
ALTER PROC [dbo].[$_Rpt_vehicle]
@Card VARCHAR(16),
@txtLog_Date Datetime,
@txtCompleted_Date DatetimeAS SET NOCOUNT ON
BEGIN
set @card = @cardSELECT cardno, trdate
FROM VW_RPT_van2
where
cardno = @Card
and
trdate between @txtLog_Date and @txtCompleted_DateEND
----------------------------- end of sp --------------------------
FYI, my sp is able to display all those record which are based on cardno and txtlog_date and txtCompleted_date
how can I modify the ashx so that I can display record on my asp page?TQ

Hi Ipohtech,
I don't know how to MS Visual studio for this task. I will try to use ms edge developer tool by pressing F12 on the asp page...Hope I can able set the breakpoint at the ashx file with the mentioned line ..FYI, the asp page is to call ashx file , If I set breakpoint F9 onto that asp page, will it able to go to ashx file?
Firstly, the browser develop tool(F12) is not as same as the visual studio develop tool, you couldn't set the breakpoint in the visual from the browser.
I suggest you could set the breakpoint directly in the ashx file in VS.
Then if the request send into the ashx, it will fired the breakpoint.
Best Regards,
Brando
