I am a asp.net learner. I have got seven textbox and a button on the page. I should be able to write text in the textboxes and save them in access database. I can run it OK, but when I write something in the texboxes and try to save it I get the following error.
'OleDbException was unhelded by user code'
also the following,
'Could not find file C:mohammadpweb_devcustomer.mbd'
I'm stuck with this query. I've tried a lot but ended up with no clue. Here is my sql query which is worrying me.. sqlselect = "select qo.OrderDate,qo.RequiredDate,qo.ShippedDate" & _
View 13 Repliesi'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.

I have a simple update query to a access database. Works perfectly on my localhost but when I upload it to the server it displays this. The weird thing in the "
monstababy.MailingList.btnSubmit_Click(Object sender, EventArgs e) in C:inetpubwwwrootmonstababymonstababymonstababyMailingList.aspx.cs:26" mention of my
local host settings on the server. I have spoken to my host and they have set permissions for the data folder etc but this still prevails. I am positive it

I have a user control called adminMenu and I use it in my index.aspx and all is fine, but I need to access a MenuItem in adminMenu and need to change NavigateUrl on the MenuItem. Tried this code with no luck:
MenuItem MaintenanceReports = this.adminMenu.FindItem("MaintenanceReports");
Not sure if I should be accessing adminMenu properties from controls code behind, but when I try from controls code behind was not able to access it either.
I have to access the parent form's controls inside an event handler method on my user control's code behind.

View 7 RepliesI'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.
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
Event Source: ASP.NET 2.0.50727.0
This is completely preventing access to the web site. Every attempt to access the website results in one of those error messages appearing in the event viewer. If I enable custom error pages on the website, I can see that same error.I have not been able to find any information whatsoever on what could be causing this.
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 ??

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'.
Look below this codes throw me : FormatException was unhandled by user code
Codes:
satis.KDV = Decimal.Parse((from o in genSatisctx.Urun where o.ID == UrunID select o.Kdv).ToString()); How can i rewrite linq query?
You can for example enter the length and width of the web (VS.NET2005), when it runs out of range index error exception was unhandled by user code for chieudai
Code:

Is there anything missing in IIS 6.0 that prevents me from (Insert into table) using MS-Access?
Explain: The application works fine under Visual Studio 2008 IDE the insert into table works fine with no error, Also I tested with hosting provider and works fine with no problem. but now I have published the same exact app in a dedicated server windows 2003 with
IIS 6.0 .NET framework 2.0 with latest service pack I gave IIS_WPG write/modify access to the folder where MS-Access database is located and database but at the time of insert an error pop-up. I need to install in the Server or settings in the IIS to recognize my MS-Access db is it some office runtime that I am missing. (BTW I am using OLEDB connection string in my C# )
Using System.Data.OleDb;
I can retrieve data off of it with no problem but when I try to insert is when it fails I thought the problem was Access Rights but I do not think is the case.
I am getting the error 80070005 access denied while trying to create a ms-word document dynamically through the c# code. For this I have to register COM Library to IIS. I want to know how to register a COM Library to IIS using regsvr32.
View 1 RepliesI'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:

The exception is thrown on the "da.Fill(_transactions)" line.
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.
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?
protected void Page_Load(object sender, EventArgs e)
