For some reason it's flagging the 2nd line in the GetJacketByPolicyID function saying the specified cast is not valid. So I'm guessing it's something I'm doing wrong. I'm sure the tblPolicy/tblPolicies class works right since I can create a new instance of a tblPolicy and set a few variables by hand and return it, so that's not it. I've also checked the datarow I'm fetching and there's no null values in the record, so that shouldn't be it either.

I have a .Net 2 solution with some asp classic pages.I get a specified cast is not valid error when I access the page on my local. Below is the vb function where I get the Error:

At first, I thought the problem is with the source code and we were thinking the source code we have is different with the ones deployed on test and prod servers. But when I tried to upload it on the test server, I don't get the specified cast is not valid error.
have a table that keeps track of customer data that is beyond the scope of the Membership Class, this table I am also using the Membership.CreateUser() generated user ID.When I use my INSERT statement however to create a new row in my table I keep getting the Specified cast is not valid error.This is my SQL Command (The ...refer to other fields)
Dim mySqlCommand As String = "INSERT INTO Customers (UserID, ...) VALUES (@UserID, ...)"
I send it to my Write_Database(mySqlCommand, Membership.GetUser(txtUserName.Text).ProviderUserKey, ...) function which then
I also tried sending he UserID as: CType(Membership.GetUser(txtUserName.Text).ProviderUserKey, SqlGuid)
Neither Works...both cause errors...My Write_Database Function is declared as follows:
Public Function Write_Database(ByVal MysqlQuery As String, ByVal UserID As System.Data.SqlTypes.SqlGuid, ...)
However Visual Studio shows that the error originates in the function calling code...
I have a complicated join between a few tables but I have managed to replicate the error using linqpad and the small tables below. There are references between the COLNAME column and the YAXIS column and also between COLNAME and XAXIS that is not explicitly defined.
The error is "Specified cast is not valid", which originally I wasted time thinking the problem was converting the data returned to my object in VS 2010, but the error also happens in linqpad with no defined object. It seems insane that a bit column would cause this problem. If I change the column type to a VARCHAR it works fine. If I run the generated SQL from linqpad or sql profiler that also returns fine.

There is select and update SQLs in sqldatasource and checkbox in formview which is 2way databinded to an sqlserver bit field type.
it always gives same error
Specified cast is not valid
I excpect nobody posts me an "eval" solution.because update is a need for checkboxes which are attached to a bit field.

I have a custom oledb role provider that pretty much a cust and past of:
[URL]
except I've used oledb instead of odbc. I'm connecting to an oracle database and the tables have been created with out any issues. now if I go into the Website Administration Tool and try to create a new role I get the error
"Specified cast is not valid."
I can create a role directly in the database (through TOAD) and the role will show up in the .NET WAT, so I know it can make the connection and read the info just fine. I just can't create or delete or modify a role without the above error.
I'm using C# in VS 2008 Pro.
My provider code is as follows:

I've written a View (form) that has a section with two radio buttons and a blank <DIV> block that will dynamically be updated. When one radio button is clicked, a <DIV> on the page is updated with fields specific to that radio button option. When the other radio button is clicked, the <DIV> on the page is updated with fields specific to that radio button option. To determine what content gets displayed when a radio option is selected, I call a JavaScript function and set the content appropriately using jQuery. Pretty easy so far. Let's assume that the User has toggled the radio buttons and filled in some data. Further down in the form, the User has entered an invalid e-mail address. When the User submits the View, the ModelState is invalid. If it is invalid, I return the View.
[Code]....
Problem is, when the View is returned, some of the form fields (that are static) are in place. However, the <DIV> that was previously updated based on User radio button selections is reset to its original state. When we return a View because of an invalid Model State, is MVC smart enough to return the View in it's modified state (in this case, with the modified DIV and dynamically added content)?
In Asp.net application. i cache a Linq to Xml result to a Cache object. when i cast the cache object back to generic list. i get the following exception.
[A]System.Collections.Generic.List`1[CarRentalAddress] cannot be cast to [B]System.Collections.Generic.List`1[CarRentalAddress]. Type A originates from 'mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' in the context 'LoadNeither' at location 'C:WINDOWSassemblyGAC_32mscorlib2.0.0.0__b77a5c561934e089mscorlib.dll'.

My code looks like this.
if (!Page.IsPostBack) { if (Cache["xml"] == null) { DataSet ds = new DataSet(); ds.ReadXml(HttpContext.Current.Server.MapPath("~/CarRentalAddress.xml")); var grid = (from d in ds.Tables[0].AsEnumerable() orderby d.Field<string>("City") where d.Field<string>("Enabled") == "1" select new CarRentalAddress { City = d.Field<string>("City"), HotelName = d.Field<string>("HotelName"), Address = d.Field<string>("Address"), EmailID1 = d.Field<string>("EmailID1"), EmailID2 = d.Field<string>("EmailID2") }).ToList(); Cache["xml"] = grid; totalrows = grid.Count().ToString(); grdAddress.DataSource = grid; grdAddress.DataBind(); } else { //Exception is thrown by this line var grid = (List<CarRentalAddress>)Cache["xml"]; totalrows = grid.Count().ToString(); grdAddress.DataSource = grid; grdAddress.DataBind(); } }
The error that I get from this code states that the cast is invalid and that the number must be less than infinity. [Code]....
By the way, I tried to paste my code using the icon from the toolbar but it didn't work. Firefox problem maybe?

The problem is that this is occurring only on our servers, not on our local development boxes. I've tracked it down to a single property we're modifying:
event.SalesForceId = "701Q0000000AOTIIA4";
If I comment out that line, everything works fine.
I've tried:
1 ) waxing all of the code on the server and redeploying. Same issue.
2 ) Pulling down a copy of the server DB and trying it locally. Works fine.
3 ) Trying another IIS environment we have setup on the same box. Same issue.
4 ) Physically comparing ( using AdeptSQL ) both local and remote schemas. No differences.
5 ) Verifying the datatypes of both columns ( local and remote ) are the same. Also, this column is a FK to another table. I verified that both are of the same data type, down to the collation.
The server is Windows Server 2008 and the local box is Windows 7 x64. Both have all important updates setup.
The only thing I can think of is perhaps since the database and web server are on different boxes that could be an issue? Otherwise, I'm completely stumped.

I am getting a parameter is not valid exception..While saving the image
Here is my code to save the image
if (!File.Exists(pictureBox1.Tag.ToString()))
{
Image image = pictureBox1.Image;
image.Save(pictureBox1.Tag.ToString(), ImageFormat.Jpeg);
}
else
{
string delStr = pictureBox1.Tag.ToString();
pictureBox1.Image.Dispose();
File.Delete(delStr);
Image image = pictureBox1.Image;
image.Save(delStr, ImageFormat.Jpeg);
pictureBox1.Image = Image.FromFile(delStr);

I have implemented the following functionality that connects to webservice and downloads a favicon from a given site and saves it to a byte[] which I store in our database. I now want to set it up so that it saves the icon to the disk. However I am getting a "Parameter is not valid" when I try and create the image from the byte[].My code is as follows..
stream.Write(imageByteArray, 0, imageByteArray.Length);
Image i = Image.FromStream(stream); // EXCEPTION HAPPENS HERE.
i.Save(@"C: mp" + filename + ".ico");
The exception occurs on the middle line. This code works perfectly 9 times out of ten, but for some favicons, even thought the icon is a valid image (or at least it appears to be and it shows in the browser when point at it) I get this exception. Does anyone have any ideas? I am pulling my hair out here!
