I have built a dataset named Transaction_Time.I called it on Page_Load
Transaction_Time tranTme = new Transaction_Time();
put it in the session.
Session["Transaction"] = tranTme;
Then I call that session and cast to dataset.
DataSet dstTranTime = (DataSet)Session["Transaction"];

Above is my code. The error I'm get is, Unable to cast object of type 'System.DateTime' to type 'System.String'.
The column "To" and column "Subject" are strings and column "Receive" is DateTime. I can't made any changes in the database, so I need to write some code to handle casting a string to datetime or if statement as a work around.

This error is occuring randomly, and I can't seem to pinpoint what is causing it. For the most part, the code works fine. I'm confused why it works sometimes, but then suddently craps out on me, lol.It happens in the code when I call upon the asp.net membership provider. It only seems to happen when i use Membership.GetUser() to grab the logged in user's information.
View 9 RepliesI have installed the final version of Crystal Reports for Visual Studio 2010. I created a new ASP.Net project, saved it, closed it, and then came back to it later. I was prompted to convert the project because of an out of date version of Crystal Reports. But I just created the project...how can the version already be out of date? Also, once the conversion is complete the CrystalReportViewers error stating "Unable to cast object of type 'CrystalDecisions.Web.CrystalReportViewer' to type 'CrystalDecisions.Web.CrystalReportViewerBase'. I am using .NET Framework 3.5 (I cannot use 4.0 for other reasons). Is this the cause?
View 2 RepliesI have on my page.aspx CheckBox with IDs representing the month.
<asp:CheckBox ID="January" runat="server" Text="Janvier" />

The ChecBox will be selected according to the user need: 1, 2, 3 or plus... When the page is fired, I wanted to get in the code behind the box which are checked so I can build a query consequently. So in the code behin, i wrote this:
Dim MyCheckBox As CheckBox
Even if I try Dim MyCheckBox As New CheckBox I was getting the same error below.
For Each MyCheckBox In Form.Controls
For j As Integer = 1 To 12
If TypeOf MyCheckBox Is CheckBox Then
MyCheckBox.ID = MonthName(j)
If CType(MyCheckBox, CheckBox).Checked = True Then
TargetedFieldName = MyCheckBox.ID
'Build a query against tables
MyCheckBoxCollection += TargetedFieldName & ", "
End If
End If
Next
