System.FormatException

Hi Guys,

When I trying to execute this code,

insGrupo = Nothing
insGrupo = New Grupo(Short.Parse(0), TxtGrCoCodi.Text)

occurs the following error

System.FormatException: Sequence of entrance was not in a incorrect format.

Somebody knows what it can be this error?

System.IndexOutOfRangeException

I have the following code...

Public Sub SelectPieceByProductID()

Try

Dim arParams(0) As SqlParameter

arParams(0) = New SqlParameter("@dotnet.itags.org.lProductID", lProductID)

Dim oDR As SqlDataReader =
oData.ExecuteReader(sConnectionString, CommandType.StoredProcedure,
"spSelectPieceByProductID", arParams)

If oDR.HasRows Then
Do While oDR.Read()
sPieceNumber = CType(oDR.Item("PieceNumber"),
String)
lMetalID = CType(oDR.Item("MetalID"), Long)
lTotalCount = CType(oDR.Item("TotalCount"), Long)
dTotalWeight = CType(oDR.Item("TotalWeight"),
Double)
--> lNonCenterCount =
CType(oDR.Item("NonCenterCount "), Long)
dNonCenterWeight =
CType(oDR.Item("NonCenterWeight"), Double)
dPrice = CType(oDR.Item("Price"), Double)
lMarkup = CType(oDR.Item("Markup"), Long)
bActive = CType(oDR.Item("Active"), Boolean)
bDeleted = CType(oDR.Item("Deleted"), Boolean)
Loop
End If

oDR.Close()

oDR = Nothing
oData = Nothing

Catch ex As Exception

End Try

End Sub

I am getting an "System.IndexOutOfRangeException" exception on the
marked line. All values prior to this line are being set correctly.
Anyone see the issue here? I run the query in query analyzer with the
appropriate id and it works fine.

I'm clueless.

Thanks.It seems that the NonCenterCount column does not exist. Perhaps the column
name is mispelled either here, or in the table definition.

System.IndexOutOfRangeException

Hello,

I have the following code where all the used variable are declared to their respective types:

insertSql = "SELECT Max([Customer ID]) AS CustID FROM [Registration Info]"
objCommand = New OleDbCommand(insertSql, objConn)
objConn.Open()
objDR = objCommand.ExecuteReader()

While objDR.Read()
CustID=objDR("Cust ID") '********** (1.)
End While

I am getting an error on (1.). its says "System.IndexOutOfRangeException: Cust ID" why is this happening? Can comeone help me whith this problem?

Thanks,
~sIf the code enters the while loop then tere are values within objDR so why not add a watch to this and check the value of objDr(0) and then objDR(1)

Hope that helps

Cheers
Gregor Suttie
I would say it is happening because there is no field in the result called "Cust ID", though there is one called "CustID"
Yes i know thats a silly mistake on my part. very silly... i wish i could delete this post. :) thanks very much. now i am doing it like objDR(0)

Regards.

System.IndexOutOfRangeException: Index was outside the bounds of the array

Hi i am getting the following error "System.IndexOutOfRangeException: Index was outside the bounds of the array". it is coming from this line of code ;

Line 595: // Build Column Name PartLine 596: strPart1 = strPart1 + "`" + strData[lngIter, 0] + "`,";Line 597:

It may have been caused by the following code;

staticpublicstring buildQuery(string strAction,string strTableName,string[,] strData,string[,] strWhere,string strWhereOverride,string strLimit,string strOffset,string strOrderBy){
// Array Definitions
//strData(x,0)=ColumnName
//strData(x,1)=ColumnData

You will get this if you use an index that is higher than the number of items in the array. So check if the lngIter is within the index range of the array so you don't pass an index which is higher than the total amount of items in the array.

Hi, i am quite new to programming, so i am unsure if i have declared the arrays properly, however i will show you some code and if you could tell me if you can identify where i have to declare the array.;

The following code is in the page calling up a method;

clsOBJ objDHOC =newclsOBJ();

Pmillio.clsOBJ.buildQuery("INSERT","tblProperty", strData, strWhere,"","1","1","strData");

string[,] strData =newstring[11, 2];

string[,] strWhere =newstring[11, 3];

strData[0, 0] ="StatutoryDate";

strData[0, 1] = txtDate.Text;

The following code is what in the DAL which the one above is referencing;

staticpublicstring buildQuery(string strAction,string strTableName,string[,] strData,string[,] strWhere,string strWhereOverride,string strLimit,string strOffset,string strOrderBy)

{

// Array Definitions

//strData(x,0)=ColumnName

//strData(x,1)=ColumnData

// Ucase

strAction = (strAction);

// Dimension

string strSQL;

int lngIter;

string strPart1 =null;

string strPart2 =null;

System.InvalidCastException:

I get a System.InvalidCastException on the following code.

ObjtInterestLadder.dblPrinCcyAmt = (double) dsRecs.Tables["DetailData"].Rows[iSub]["Prin_Ccy_Amt"];

Why is this.

When I retrieve the data to a string it is OK

sData = (string) dsRecs.Tables["DetailData"].Rows[iSub]["Prin_Ccy_Amt"].ToString();

have you checked for NULL values?

What is it showing when you do that ? If it is null or blank it will show exception.

I can't figure out what's going on either, since you did not tell us which
line was causing the error.
This sort of thing happens frequently when a database column contains NULL.
NULL is not a value, so if you try to treat it as a string, you'll get the
invalid cast exception.

John,
My frustration is that it works on my PC that has Framework 1.1.
But when I move it to production that has framework 1.0, it does not
work.
I have the backward compatibility turned on, so it should work.
Since it is on production, i don't have an easy way to debug.
All I could do was set debug=true on web.config and look at the
trace.axd to get that error.
Is there an easy way for me to find out what line is actually giving me
that error?
thanks...

I don't know, but this kind of thing is a reason to develop on the platform
you're going to use in production.

Ok, if there's something on that line that ASP.NET doesn't like, then
simplify it:
Dim projectColumnName as String =
AtRiskProjDS.AtRiskProjects.ProjectColumn.ColumnName
Dim atRiskCodeColumnName As String =
AtRiskProjDS.AtRiskProjects.AtRiskCodeColumn.ColumnName
Dim query As String = projectColumnName & "= '" & strProject & "' AND " &
atRiskCodeColumnName & "= '" & strAtRiskCode & "' "
Dim rows() As AtRiskProjectsDS.AtRiskProjectsRow =
AtRiskProjDS.AtRiskProjects.Select(query)
Try that and tell us which line has the problem.
John Saunders
I had defined rows() variable as my dataset.datatablerowtype.
eg.
Dim rows() As AtRiskProjectsDS.AtRiskProjectsRow
Framework 1.0 did not like it.
After I changed the rows() variable to simple datarow type as shown
below, it worked fine.
Dim rows() As datarow
Just so if anyone has this problem in the future.

I can't figure out what's going on either, since you did not tell us which
line was causing the error.

This sort of thing happens frequently when a database column contains NULL.
NULL is not a value, so if you try to treat it as a string, you'll get the
invalid cast exception.

John Saunders

John,
My frustration is that it works on my PC that has Framework 1.1.
But when I move it to production that has framework 1.0, it does not
work.
I have the backward compatibility turned on, so it should work.
Since it is on production, i don't have an easy way to debug.
All I could do was set debug=true on web.config and look at the
trace.axd to get that error.
Is there an easy way for me to find out what line is actually giving me
that error?

thanks...

I don't know, but this kind of thing is a reason to develop on the platform
you're going to use in production.

John Saunders
Here is my DeleteProject method.
Dim rows() As AtRiskProjectsDS.AtRiskProjectsRow =
AtRiskProjDS.AtRiskProjects.Select(AtRiskProjDS.At RiskProjects.ProjectCo
lumn.ColumnName & "= '" & strProject & "' AND " &
AtRiskProjDS.AtRiskProjects.AtRiskCodeColumn.Colum nName & "= '" &
strAtRiskCode & "' ")

is the statement that is not being liked for some reason.

Sub DeleteProject(ByVal Project As String, ByVal AtRiskCode As String)

Try
Dim strProject As String = Project
Dim strAtRiskCode As String = AtRiskCode

Dim rows() As AtRiskProjectsDS.AtRiskProjectsRow =
AtRiskProjDS.AtRiskProjects.Select(AtRiskProjDS.At RiskProjects.ProjectCo
lumn.ColumnName & "= '" & strProject & "' AND " &
AtRiskProjDS.AtRiskProjects.AtRiskCodeColumn.Colum nName & "= '" &
strAtRiskCode & "' ")
Trace.Write("proj1: " & strProject & ", code1: " &
strAtRiskCode)
Dim r As AtRiskProjectsDS.AtRiskProjectsRow

If rows.Length <> 0 Then
r = rows(0)
r.Delete()
End If
Catch ex As Exception
Trace.Write(ex.ToString)
End Try
End Sub

Ok, if there's something on that line that ASP.NET doesn't like, then
simplify it:

Dim projectColumnName as String =
AtRiskProjDS.AtRiskProjects.ProjectColumn.ColumnNa me
Dim atRiskCodeColumnName As String =
AtRiskProjDS.AtRiskProjects.AtRiskCodeColumn.Colum nName
Dim query As String = projectColumnName & "= '" & strProject & "' AND " &
atRiskCodeColumnName & "= '" & strAtRiskCode & "' "
Dim rows() As AtRiskProjectsDS.AtRiskProjectsRow =
AtRiskProjDS.AtRiskProjects.Select(query)

Try that and tell us which line has the problem.

John Saunders
I had defined rows() variable as my dataset.datatablerowtype.
eg.
Dim rows() As AtRiskProjectsDS.AtRiskProjectsRow

Framework 1.0 did not like it.

After I changed the rows() variable to simple datarow type as shown
below, it worked fine.

Dim rows() As datarow

Just so if anyone has this problem in the future.

System.InvalidCastException: Specified cast is not valid.

I have an table with a field of bit. the fields name is Active.
When trying to add that field to a label it gives me the following.
It all works when not using this field.

Error : System.InvalidCastException: Specified cast is not valid.
get {
Line 2057: try {
Line 2058: return ((bool)(this[this.tableJob_Posts.ActiveColumn]));
Line 2059: }
Line 2060: catch (System.InvalidCastException e) {

My code is as follows.

jpDT = jpTA.GetJob_PostsByJobID(jid);

foreach (DataSet1.Job_PostsRow jprin jpDT)

{

if (jpr.Active !=null)

{

this.ActiveLabel.Text = jpr.Active.ToString();

}

Is this field nullable in the database, and are you using TableAdapters? If so, can't simply check for null. You need to instead call the method IsActiveNull() which will be auto-generated by your row class if the field is nullable. This will then check for DbNull instead of null.

System.InvalidOperationException: Collection was modified; enumeration operation may not e

hi all,

i am getting the following error when i am trying to move the ltems form listbox1 to listbox2

"System.InvalidOperationException: Collection was modified; enumeration operation may not execute"

ForEach itemAs ListItemIn Listbox1.Items

If item.SelectedAndNot Listbox2.Items.Contains(item)Then

Dim newItemAsNew ListItem(item.Text, item.Value)

Listbox2.Items.Add(newItem)

listbox1.Remove(newitem)

EndIf

thanks.

You can't modify the listbox1 item collection while you are iterating over it using "for each". Wait until you add everything to listbox2, and then call Clear() on listbox1.

System.InvalidOperationException: Application is restarting

Hi All,

I am getting the following exception in an ASP.NET
application.

Exception Details: System.InvalidOperationException:
Application is restarting.

I have been to the following Support page

http://support.microsoft.com/default.aspx?kbid=312592

and disabled the Realtime monitoring. But, I was not able
to solve the issue.

Any suggestions are greatly appreciated.

Thanks a lot in advance,

Regards
HariHi,

There are vast spectrums of situations that can cause application
restarting. I suggest that you find first the line that causes
application to restart. Start with simple application to check out if
this problem is application specific. If this is the case and other
application doesnt cause recycling you should find the application line
that cause recycling.

Thanks Natty for your prompt reply. Unfortunately I don't
have the real access to the code at the moment and I am
kind of new to ASP.NET. But, I understand the technology
well.

The following is the exception I was getting when this
error occurs: Please have a look if it makes sense. Any
advice from your side is greatly respected.

Hi,

Nothing special with excaption stuck. it's regular operations that
called while loading a page. try to delete the temporary directory of
your application under
""C:\WINDOWS\Microsoft.NET\Framework\v1.0.3705\Tempo rary ASP.NET

System.IO.IOException: Cannot create a file when that file already exists.

Getting the following error on my production server whether the file exists
or not:

"System.IO.IOException: Cannot create a file when that file already exists."

Here's the code generating the error (seems to be happening when I try
creating a directory)

If dirmgr.Exists("s:\blah\" & txt_name.Text) Then
lblerror.Text = lblerror.Text & "Unable to build physical path. " &
txt_name.Text & " & Contact Dev Team.<BR>"
Else
dirmgr.CreateDirectory("s:\blah\" & txt_name.Text)

This code runs fine on my development server (only the path is c:\blah\blah
instead of S). Also, my production server has failover cluser, and the s
drive is the failover drive. I can't imagine that could be a problem, but
thought I would mention it.

Asside from that, the only other thing I can think of is that the framework
version on my dev box says 1.1, and the one on my production server says:
1.0.37 - surely that's not the cause is it? Permissions shouldn't be an
issue (i've even tried as domain admin)

I would appreciate any help on this, as I'm out of ideas, and can find no
other documentation on this.

I agree with Natty. The problem you are having is most likely caused by
having no right to access network resources. Willy address a similar
problem before. See

Thanks for the response.

I understand that, but I'm trying to create a directory on the local drive.
This isn't a mapped share. The drive is physically present on the web
server, and if that web server fails, the other system physically takes over
the drive (ie, a cluster). I've also added the local ASPNET account to the
NTFS permissions on the folder, and it still fails.

It doesn't work creating folders under the same directory as the web
application... same issue.

I'm going to try figuring out why that server is showing that it's running
version 1.03 of the dotnet framework. It shows that v1.1 was installed.

Thanks,
Chad

Chad, was the problem resolved? It seems that you installed both v1.03 and
v1.1 on the same web server. If so, it might be helpful to look at the
article "Compatibility Considerations and Version Changes" on
http://www.gotdotnet.com/team/changeinfo/default.aspx. Try configuring your
web application to run V1.03 and V1.1 specifically to see how it works.

Allen,

Thanks for the followup. I actually got my program working late last night.
The problem was the framework version.

I tried simply configuring the web application to use version 1.1, but that
didn't help. I also tried uninstalling then reinstalling framework version
1.1, but that also didn't get IIS to start using version 1.1 by default. I
consequently uninstalled versions 1.1 *and* version 1.03, then only
reinstalled version 1.1 again, and this took care of the problem.

Thanks again for all the help everyone!

- Chad

System.IO?

If I am not wrong, System.IO is one of the seven namespaces that get
imported in all ASP.NET page automatically but in the following code:

<%@dotnet.itags.org. Import Namespace="System.IO" %>
<script runat="server">
Sub Page_Load(ByVal obj As Object, ByVal ea As EventArgs)
Dim ioFileInfo As New FileInfo("C:\Inetpub\wwwroot\File1.asp")

lblOutput.Text = "Name: " & ioFileInfo.Name & "<br>"
lblOutput.Text += "Path: " & ioFileInfo.DirectoryName & "<br>"
lblOutput.Text += Last Accessed: " & ioFileInfo.LastAccessTime
& "<br>"
lblOutput.Text += Last Written: " & ioFileInfo.LastWriteTime &
"<br>"
lblOutput.Text += Size: " & ioFileInfo.Length & " bytes"
End Sub
</script>
<form runat="server">
<asp:Label ID="lblOutput" runat="server">
</form>

if I get rid of the <%@dotnet.itags.org. Import....%line, then ASP.NET generates the
following error:

Type 'FileInfo' is not defined.

pointing to the very first line within the Page_Load sub (Dim
ioFileInfo As New FileInfo...).

Why?

Please correct me if I am wrong.

Thanks,

You are wrong.

If you wish to use System.IO, you must import it explicitly.

System.Collections
System.Web
System.Web.UI
System.Web.UI.HtmlControls
System.Web.UI.WebControls

I hope the above 6 namespaces "do" get imported automatically by all
ASP.NET pages. If not, then please let me know. God knows what all I
must have learnt wrong from that ASP.NET book!

BTW, are there any additional namespaces apart from the above 6 that
all ASP.NET pages import automatically?

Thanks once again,

Arpan,
If you do not see it in the using .. list (or "Import" in VB.NET) when you
create a class or web page, then you need to explicitly add it an ensure that
the project has a reference to the namespace assembly. If it isn't there, you
will find out about it very quickly!

In ASP.NET 2.0, the default namespaces are defined in the default web.config, located in :
Drive:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\ CONFIG

Here they are :

You could add System.IO, so it's automatically imported, by adding :

to the <namespacessection of web.config.

Of course, any other namespace you want to import automatically can also be added.

Look in <framework dir>\v2.0.50727\CONFIG\web.config.comments under the
compilation section to see the default imports (there are nine).

For 1.1 look in <framework dir>\v1.1.4322\CONFIG\machine.config. There
are eight listed there. The new one in 2.0 is System.Configuration.

Kevin,

don't you consider mscorlib to be one of them ?

Also, doesn't the vbc compiler automatically import Microsoft.VisualBasic ?

Also, isn't the list supplied in the default web.config's pages element accurate ?

Won't any namespace defined in web.config be automatically imported,
and you will not have to import it specifically ?

Ah! I don't do VB, so I didn't look :)

Yep, but I was listing the assemblies not the namespaces, which of
course I should have been.
