Hello Experts,
We are building an app that allows users to make online reservations of our facility.
The code below is designed to allow users to perform a search by either specific date or by date range.
Users can also search by selecting a search option from the dropdownlist.
The way the code works currently, if user's search turns up nothing, then we get the following error message:
Object reference not set to an instance of an object.
Line 259: Dim lblcurrentpage As Label = DirectCast(gvrow.Cells(0).FindControl("CurrentPage"), Label)
Rather than the error message, w would like the code to work differently.
If user's search is successful, the results of his/her search is displayed.
If however, no data is found based on his or her search parameter, we would like to display one month's worth of results.
Is this possible?
Below is the current code we are using.
Private Sub showGrid()
' Set the value of the SearchString so it gets
SearchString = txtSpecificDate.Text
ViewSelect = Request("ViewBy")
If ViewSelect = "" Or ViewSelect = "Range" Then
ViewSelect = "Range"
Else
ViewSelect = "Specific"
End If
'Response.Write(ViewSelect)
'Response.End()
Dim strQuery As String
Dim strSearch As String
Dim receiveddate As String = txtSpecificDate.Text
Dim fromdate As String = txtFromDate.Text
Dim enddate As String = txtToDate.Text
' Dim dts As DateTime = DateTime.ParseExact(DateString, "MM/dd/yyyy", CultureInfo.InvariantCulture)
'Protect against SQL Injection
strSearch = Replace(receiveddate, "'", "''", 1, -1, 1)
fromdate = Replace(fromdate, "'", "''", 1, -1, 1)
enddate = Replace(enddate, "'", "''", 1, -1, 1)
receiveddate = DateTime.Today.ToString("MM/dd/yyyy")
fromdate = DateTime.Today.ToString("MM/dd/yyyy")
enddate = "12/31/2050"
' first: Do we use AND or OR between clauses in the WHERE?
Dim andors As String = ANDOR.SelectedValue
'Response.Write(andors)
'Response.End()
' and now build up the WHERE.
'First, initialize where just to make sure it has nothing prior to our search
Dim where As String
where = ""
Dim facilityT As DropDownList
facilityT = FindControl("DropDownList1")
If facilityT.SelectedValue <> "" Then
If where <> "" Then where = where & andors
where = " i.instructorName = '" & Replace(facilityT.SelectedValue, "'", "''") & "'"
End If
If ViewSelect = "Range" Then

where = where & " CONVERT(VARCHAR(10), d.trainingDates, 101) >= '" & fromdate & "' AND CONVERT(VARCHAR(10), d.trainingDates, 101) < '" & (enddate) & "'"
End If
If ViewSelect = "Specific" Then
If where <> "" Then where = where & andors
where = where & " CONVERT(VARCHAR(10), d.trainingDates, 101) = '" & strSearch & "' "
End If

Don't do that! 
The only way to truly protect against SQL injection is to use a parameterized query. It's not even difficult:
Dim cmd As New SqlCommand("-placeholder-", conn)
Dim sb As New StringBuilder( *** BASE QUERY HERE, up to but not including the "where" keyword *** )
Dim andors As String = IF(ANDOR.SelectedValue = "OR", " OR ", " AND ")
Dim startedWhere As Boolean = False
If facilityT.SelectedValue <> "" Then
sb.Append(If(startedWhere, andors, " WHERE "))
sb.Append("i.instructorName = @InstructorName")
cmd.Parameters.AddWithValue("@InstructorName", facilityT.SelectedValue)
startedWhere = True
End If
If ViewSelect = "Range" Then
sb.Append(If(startedWhere, andors, " WHERE "))
sb.Append("d.trainingDates Between @FromDate And @EndDate")
cmd.Parameters.AddWithValue("@FromDate", Date.Parse(fromdate))
cmd.Parameters.AddWithValue("@EndDate", Date.Parse(enddate))
startedWhere = True
ElseIf ViewSelect = "Specific" Then
sb.Append(If(startedWhere, andors, " WHERE "))
sb.Append("d.trainingDates = @SpecificDate")
cmd.Parameters.AddWithValue("@SpecificDate", Date.Parse(strSearch))
startedWhere = True
End If
cmd.CommandText = sb.ToString()

Hi Richard
Ever since I started posting here, you have save me a lot - Thank you very much.
Does your solution include the core question that I have about presenting one month's data if user's search turns up nothing?
Also, I am not sure I understand the difference between
Dim cmd As New SqlCommand("-placeholder-", conn)
and
Dim sb As New StringBuilder( *** BASE QUERY HERE, up to but not including the "where" keyword *** )
I know the sqlcommand(..) is this:
SELECT L.LocationId," & _
"c.courseId, " & _
"c.coursename, " & _
"CASE WHEN L.Seating_Capacity - COALESCE(TS.TakenSeats,0) = 0 THEN 'Not Available' " & _
" ELSE 'Available' END AS 'AvailableSeats'," & _
"d.dateid, " & _
" d.trainingDates, " & _
"d.trainingtime, " & _
" c.CourseDescription, " & _
" i.instructorName, " & _
"l.location " & _
" FROM tblLocations L " & _
" Inner Join tblCourses c on l.locationId = c.locationId " & _
" Inner Join tblTrainingDates d on c.dateid=d.dateid " & _
" Inner Join tblCourseInstructor ic on c.courseId = ic.CourseId " & _
" Inner Join tblInstructors i on ic.instructorId = i.instructorId " & _
" OUTER APPLY (Select Count(*) TakenSeats " & _
" FROM tblTrainings T " & _
" where(L.LocationId = T.LocationId) " & _
" AND c.courseId = t.courseId) TS where "
but I don't understand what goes into the stringbuilder(...)

The "-placeholder-" string in the SqlCommand constructor doesn't need to be changed. It's just there so that the command has some initial text which is obviously not a query. That text will be replaced later, once the full query has been built. (cmd.CommandText = sb.ToString())
The *** BASE QUERY HERE ... *** part needs to be the base query, up-to but not including the final "where" statement:
Dim sb As New StringBuilder("SELECT L.LocationId," & _
"c.courseId, " & _
"c.coursename, " & _
"CASE WHEN L.Seating_Capacity - COALESCE(TS.TakenSeats,0) = 0 THEN 'Not Available' " & _
" ELSE 'Available' END AS 'AvailableSeats'," & _
"d.dateid, " & _
" d.trainingDates, " & _
"d.trainingtime, " & _
" c.CourseDescription, " & _
" i.instructorName, " & _
"l.location " & _
" FROM tblLocations L " & _
" Inner Join tblCourses c on l.locationId = c.locationId " & _
" Inner Join tblTrainingDates d on c.dateid=d.dateid " & _
" Inner Join tblCourseInstructor ic on c.courseId = ic.CourseId " & _
" Inner Join tblInstructors i on ic.instructorId = i.instructorId " & _
" OUTER APPLY (Select Count(*) TakenSeats " & _
" FROM tblTrainings T " & _
" where(L.LocationId = T.LocationId) " & _
" AND c.courseId = t.courseId) TS")
The code then appends the relevant filters to the StringBuilder instance to produce the final query.
As for returning one month's data if the search doesn't find anything, you'll need to modify the If dt.Rows.Count = 0 Then ... End If block to issue a new query to return the default data. Something like:
If dt.Rows.Count = 0 Then
message.Text = "No matching records found."
cmd.Parameters.Clear()
cmd.Parameters.AddWithValue("@FromDate", Date.Today.AddMonths(-1))
cmd.Parameters.AddWithValue("@EndDate", Date.Today)
cmd.CommandText = "SELECT L.LocationId," & _
"c.courseId, " & _
"c.coursename, " & _
"CASE WHEN L.Seating_Capacity - COALESCE(TS.TakenSeats,0) = 0 THEN 'Not Available' " & _
" ELSE 'Available' END AS 'AvailableSeats'," & _
"d.dateid, " & _
" d.trainingDates, " & _
"d.trainingtime, " & _
" c.CourseDescription, " & _
" i.instructorName, " & _
"l.location " & _
" FROM tblLocations L " & _
" Inner Join tblCourses c on l.locationId = c.locationId " & _
" Inner Join tblTrainingDates d on c.dateid=d.dateid " & _
" Inner Join tblCourseInstructor ic on c.courseId = ic.CourseId " & _
" Inner Join tblInstructors i on ic.instructorId = i.instructorId " & _
" OUTER APPLY (Select Count(*) TakenSeats " & _
" FROM tblTrainings T " & _
" where(L.LocationId = T.LocationId) " & _
" AND c.courseId = t.courseId) TS " & _
" where d.trainingDates Between @FromDate And @EndDate"
dt = GetData(cmd)
End If
You'll still need to modify the code which tries to find the "CurrentPage" label, in case the second query doesn't return any data either. There might not be a row, the row might not have any cells, or the cell might not contain a Label control called "CurrentPage"; any one of these things would cause your code to throw a NullReferenceException.

Thank you very much sir.
Your code is so elegant. I hope to get close to where you are one day.
I have pretty much put all the pieces together but I think I have things a bit mixed up because first, I commented out some lines that are throwing errors.
Second, when the page loads, I start paging, it starts showing some weird lines.
Can you see what I am doing wrong?

I can't see anything obviously wrong with your code. The line you've commented out would generate a compilation error, because the cmd variable is already defined towards the start of the method.

What do you mean by "weird lines"?

Sorry to keep bothering you sir and thanks for your continued assistance.
There are actually two problems that I discovered upon further testing.
1, when I select a date range with good dates - meaning dates that exist on our db, it doesn't capture them.
Instead, it displays the month values we elected to display if user's search turns up empty.
Same happens when I perform a search with specific date.
So, for some reason, the parameters are not working.
As for what I meant by weird lines, when I first run the app, it displays for instance 3 pages with a text that says, Viewing page 1 of 3. when I click page2, the text now displays Viewing page 2 of 3. However, the paging doesn't change to page 2. It still has page 1 highlighted (based on color I used).
When I attempt to click that page 2 again, I get this:
First ... Prev LinkButton LinkButton LinkButton Label LinkButton LinkButton LinkButton Next ... Last
The original code I posted wasn't doing this. It was paging perfectly only problem was that I wanted it to display one month's data if user's selection doesn't exist on the DB.

What data-type are the dates stored as in your database? They should be either date, datetime2, or something similar.
As for the paging, you haven't posted any code relating to that.

Here is the code for paging (kind of long sorry). Markup not included because I am not sure you want to see it.

page(6) = GridView1.PageIndex + 4
For i As Integer = 0 To 6
If i <> 3 Then

End If
End If
Next

lnkbtn.Visible = False
lnkbtn = DirectCast(gvrow.Cells(0).FindControl("LinkButton2"), LinkButton)
lnkbtn.Visible = False
End If

There are two things missing from the top of your updated showGrid method which were in the original code:
SearchString = txtSpecificDate.Text
ViewSelect = Request("ViewBy")
If ViewSelect = "" Or ViewSelect = "Range" Then
ViewSelect = "Range"
Else
ViewSelect = "Specific"
End If
Also, since your dates are datetime, and your original code was only comparing the date part, you'll need to update the date filters:
If ViewSelect = "Range" Then
sb.Append(If(startedWhere, andors, " WHERE "))
sb.Append("(d.trainingDates >= @FromDate And d.trainingDates < DateAdd(day, 1, @EndDate))")
cmd.Parameters.AddWithValue("@FromDate", Date.Parse(txtFromDate.Text))
cmd.Parameters.AddWithValue("@EndDate", Date.Parse(txtToDate.Text))
startedWhere = True
ElseIf ViewSelect = "Specific" Then
sb.Append(If(startedWhere, andors, " WHERE "))
sb.Append("(d.trainingDates >= @SpecificDate And d.trainingDates < DateAdd(day, 1, @SpecificDate))")
cmd.Parameters.AddWithValue("@SpecificDate", Date.Parse(txtSpecificDate.Text))
startedWhere = True
End If
I can't see any obvious reason for the paging issues. I'd probably be inclined to use a DataPager control[^] rather than custom LinkButton controls, but if your code worked with the old version of the showGrid method, it should work just as well with the new version.

Thank you so much Richard for your generous assistance.
The search by date range is working really good now.
For some reason, it wouldn't work until I changed this line:
sb.Append("(d.trainingDates >= @FromDate And d.trainingDates < DateAdd(day, 1, @EndDate))")
cmd.Parameters.AddWithValue("@EndDate", Date.Parse(txtToDate.Text))
to these lines:
sb.Append("(CONVERT(VARCHAR(10), d.trainingDates, 101) >= @FromDate And CONVERT(VARCHAR(10), d.trainingDates, 101) < @EndDate)")
cmd.Parameters.AddWithValue("@FromDate", txtFromDate.Text)
But the search by specific date is not working. It is still display the entire month which suggests it is not recognizing the date value I am passing as valid.
Don't worry, I will work this one out.
You are incredible inspiration to me on how to be patient.
Thank you very much sir.
Note: It is still exhibiting the odd behavior of displaying the weird links I posted earlier.

It seems you missing some JavaScript code related to the Ajax Toolkit, however you will have to show us code/debug to see where and what exactly the problem...

Hi,
I have this result of Guid :
d926ef0d-07df-3c5b-2246-12e061f71be1
Now i wanna to get the main string that was converted to this Guid?
Ans : the result for this guid is : "0000000000"
now My Question is :
what is the main string that converted to this GUID :
fd7bd272-f7e8-1e57-0a82-e15b79694d25
thanks in advanced!

A Guid is just a kind of 128bit number, nothing else. It is not at all a string.
If you have some strange algorithm for encoding or encrypting strings into a Guid, well, that's your own idea. We don't know how you do that. And consequently we cannot help you in reverting that strange process.
|

You may talk about a hash? Can you show us the code generates those 'GUID'...
I'm not questioning your powers of observation; I'm merely remarking upon the paradox of asking a masked man who he is. (V)

Thanks all!
But my question is how to decode ( i dont have encoding method) :
i got these from a website :
d926ef0d-07df-3c5b-2246-12e061f71be1 ------> "0000000000"
fd7bd272-f7e8-1e57-0a82-e15b79694d25 ------> "09130000000"
146b2bf5-fddb-5e68-0e9a-e5cdd19513dc ------> "0000000001"
4fb94dee-654f-55a5-5c94-71974b23fcd4 --------> "09130000001"
b69ff890-e528-a2fc-c011-8f31dcfe4794 ----> "09125395974"
f734f107-2d2c-b2e0-ed26-b92679d7cf68 ---> ???????????

You are here on CodeProject since more that 10 years. How come it you haven't learned that you must not post your question into several places?

Hai All,
I am using forms authentication and set the timeout to 539 minutes. Also I have set the session-state timeout to 540 mins in web.config. Also I have set the same in IIS manager also. But after 20 mins the session variable expires and it throws exception "Object reference not set". Could any one please tell me where I went wrong.
<authentication mode="Forms">
<forms loginUrl="~/Login.aspx" timeout="539" slidingExpiration="true"/>
</authentication>
<sessionState
mode="InProc"
cookieless="false"
timeout="540"/>
</system.web>
Code in Login.aspx.cs
Session["userprofile"] = ds;
FormsAuthenticationTicket tkt;
string cookiestr;
HttpCookie ck;
tkt = new FormsAuthenticationTicket(1, UserName.Text, DateTime.Now, DateTime.Now.AddMinutes(539), RememberMe.Checked, "your custom data");
cookiestr = FormsAuthentication.Encrypt(tkt);
ck = new HttpCookie(FormsAuthentication.FormsCookieName, cookiestr);
if (RememberMe.Checked)
ck.Expires = tkt.Expiration;
ck.Path = FormsAuthentication.FormsCookiePath;
Response.Cookies.Add(ck);
string strRedirect;
strRedirect = Request["ReturnUrl"];
if (strRedirect == null)
strRedirect = "default.aspx";
Response.Redirect(strRedirect, false);
Regards,
Rajesh Kandepu
