DataSource Controls :: Reading Excel Files To Store Into Sqlserver Database - OleDbException Was Unhandled By User Code

Feb 1, 2010

i've got some problem reading excel files to store into sqlserver database. currently my code has a fileupload control and a button for me to save the excel file into a folder and read the data inside the excel file and write it into the sql database. The code works only if the excel sheet name is Sheet1.xlsx, however i tried upload a diff file named ImportUserFile.xlsx and it gave me the exception below. 'ImportUserFile$' is not a valid name. Make sure that it does not include invalid characters or punctuation and that it is not too long. i have also tried other file names and it seemed only Sheet1.xlsx works.

Invalidcastexception - Can't Access Custom Membership User In Code

Feb 2, 2010

I've wrote a custom membership provider and a custom membership user. So far so good, I can create users / login etc, but when I try to access the custom membership user in code like this;

Code:
Public Function GetOpportunities() As IQueryable(Of Opportunity)
'Dim p As CiseroMembershipProvider = System.Web.Security.Membership.Provider
'Dim _User = p.GetUser(System.Web.HttpContext.Current.User.Identity, True), CiseroMembershipUser
Dim _User As Curve.CiseroMembershipUser = Nothing
_User = System.Web.Security.Membership.GetUser() 'Dim _CurveUser As New CiseroMembershipUser
'Return From o In Me.ObjectContext.Opportunities Where o.ClientID = User.ClientID
Return From o In Me.ObjectContext.Opportunities Where o.ClientID = _
_User.ClientID Order By o.ModifiedDate Descending
End Function
I get this error:

Unable to cast object of type 'CustomMembershipUser' to type 'Curve.CustomMembershipUser'. When I put a quickwatch on the object System.Web.Security.Membership.GetUser() it is of type CustomMembershipUser. The quickwatch window generates the text DirectCast(System.Web.Security.Membership.GetUser(), CustomMembershipUser) when I click onto the properties, but reevaluating the expression raises the error.

Web Forms :: Can't Access All Of User Control Types In Code

Jun 27, 2010

I have an asp.net 3.5 WebSite application where I have a bunch of UserControls.

In some scenarios I have a reference of type Control (System.Web.UI.Control) that I need to cast to a specific User Control type (to access public properties and methods of the User Control).

The User Control classes are all declared in "the global scope", i.e. not within a namespace. However, for some reason, only some of my User Controls is possible to type in a code file and show up in intellisense and some just wont. In one scenario I could write the cast in code anyway and the site would build (but the UserControl type name did not shift in to the ordinary class name color (light green, you know) in VS text editor), but when running the page I still get the error message about missing using directive or a reference...

If I use the VS 2010 "Navigate to" feature (Ctrl+,) and search for a type I usually get one hit for the Type/Class name and another for the actual file. When searching on my User Control class names I only get the file hits, no class representation. This even goes for those User Control types I actually can access in code.

I've tried to compare the User Control classes that work and doesn't work, but I can't find any difference, they are all declared as public partial.

I am receiving the following error on one of the web servers I support:

Event Type: Warning

C# - Trying To Access Telerik RadEditor Controls In Master Page's Code Behind As Follows... Giving Error

Nov 3, 2010

foreach (Control control in ContentPlaceHolder1.Controls)
{
if(typeof(Control).Equals(Telerik.Web.UI.RadEditor))
{
label1.Visible = true; label1.Text = "dhchk";
// control.CssFiles.Add("~/styles/myStyle.css");
}
}

Error;-

'Telerik.Web.UI.RadEditor' is a 'type', which is not valid in the given context

Also, is this the correct way to add CSS class to radEditor controls ??

control.CssFiles.Add("~/styles/myStyle.css");

I actually wanna add 3-4 customized classes..how to do that?

also I was wondering if I can add some javascript or something in my Master page that will detect the ALL the radEditor controls and set their css classes ? don't know much of Javascript..how can that be made possible? how do I go about that? but first I want css classes to be set in code behind..what's wrong with the code?

[EDIT]

@Geek..I tried calling like this..is it correct?

Control c = new Control();
DoSomething(c);

now its giving this error in the method:-

The type or namespace name 'c' could not be found (are you missing a using directive or an assembly reference?)

[EDIT]

I do have this namespace added "using System.Web.UI.WebControls;" why this error ??

Security :: Impersonation Error / .NET User Account Has To Be Given Permissions To Access The Folder

Jun 18, 2010

I wrote an asp.net application that I'm trying to run on a godaddy domain I bought. I need to read a file in a folder that I did not give read access to so that your average user cannot see in the informaion in that folder. I assumed that the asp.net program would have the same credentials as myself because server-side code. Turns out I am wrong. When I go to use the asp.net application it throws an access denied error saying that the ASP.NET user account has to be given permissions to access the folder.

After talking to two different tech support people at godaddy I've come to the realization that they are either dumb or lazy (or a combo of the two).I came across some code that you can put into the web.config file that would allow the asp.net application to impersonate a user, which would work great to use myself as the impersonated user. However it seems that godaddy cannot give me the name of the server that my domain is on (that's understandable) so I don't know what to put in the identity tag to get this to work.

Here is the code I found:

[Code]....

(of course I filled in the username and password with the correct info)

When I went to use it again it threw this error:

System.Web.HttpException: The current identity (PHX3username) does not have write access to 'C:WindowsMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files'.

Feb 17, 2010

Databases :: OleDBException: Too Many Fields Defined?

Aug 25, 2010

I'm trying to import an Excel file into a datatable. It works fine most of the time. However, I get this error when there are more than 255 columns in the Excel file. The columns are empty (after about 6 or so), but since they've been formatted it sees them anyway.My question is, is there any way around this? Can I limit the amount of columns somehow? Unfortunately, I can't just remove the columns in the Excel document, as this is being designed for users to upload documents, so I have to account for this possibility (even though most of the time there will be maximum 20 columns).Here is the code I'm using:

[Code]....

The exception is thrown on the "da.Fill(_transactions)" line.

C# - OleDBException Using Fill Method Of OleDbDataAdapter?

Nov 2, 2010

I'm using a OleDbDataAdapter object to fetch certain data from a database and place it in a data set object. The code for this is presented below:

oleConn = new OleDbConnection(WebConfigurationManager.ConnectionStrings["PTDB-ConnectString"].ConnectionString);
oleConn.Open();
oleComm = new OleDbCommand("spGetPartRevisionFromSN @SerialNumber = " + SN, oleConn);
oleComm.CommandType = CommandType.Text;
ds = new DataSet();
da = new OleDbDataAdapter(oleComm);
da.Fill(ds); //<--OleDbException occurs here

My problem is that when the program reaches the Fill method of the data adapter, I receive an OleDbException with the error being "Incorrect syntax near 'SN' ", where SN is an alphanumeric serial number. I have a few SNs that I'm testing, the pattern I notice is that the method seems to run fine with an SN that begins with a letter, e.g. "J123456", but this exception gets thrown for every SN that begins with a number, e.g. "1ABCDEF". I'm not alterting the SNs, which are just strings, in any way and I've run the SELECT query, defined in the stored procedure, in SQL Server Management Studio with both kinds of SNs without a problem.

Forms Data Controls :: Throw The Exception Back To Page_Load Error: ArgumentNullException Was Unhandled By User Code

I'm trying to throw the exception back to Page_Load but the throw statement causes error: ArgumentNullException was unhandled by user code. How can that be fixed? Also, I can't see Label1.Text displayed on the page after the ArgumentNullException occurs because the page is not re-load. If there is no exception, it's fine to not reload the page. How can I see the Label1.Text displayed?
