Failed To Convert Parameter Value From String To Int32
Jan 28, 2011
I'd like to see what is about to be sent to the SQL Server from my SqlCommand before SQLCmd.ExecuteNonQuery() runs.
I'm trying to debug because I am receiving the following error:
System.FormatException: Failed to convert parameter value from a String to a Int32.
Normally, I would use SQL Server Profiler to view what is being sent to SQL Server, but my statement is not making it that far. Is there a way to determine what it is trying to convert? I am having problems determining which parameter is causing the error.

I have an update query and I'm receiving the error "Failed to convert parameter value from a String to a Int32."
I'm assuming this is because of a format issue... I'm using Text and Date formats. I've tried a few things but I'm not sure exactly what is causing this error.[code]...

I am getting an error - "Failed to convert parameter value from a String to a Int32"
Background Information:
Table: Customer
Fields: CustomerID, Title, Forename, surname, street, town, country, postal code, home phone, mobile phone, work phone, email.
All the data types in this are Strings with the exception of CustomerID.
Table: Country
Fields: CountryID, Country
CountryID = Integer, Country = String
There is a relationship between country.country and customer.country. I have made country a combo box with the contents of country inside it. This problem is resolved if I remove country as an input - but I need it in!

I'm getting this error
Unable to cast object of type 'System.Int32' to type 'System.String'.
when doing a routine LINQ to SQL query:
Return (
From n In DbContext.Newsletters
Where n.NewsletterID = NewsletterID
[Code]....
How is it possible that an Int32 can't be cast to String? How can I debug something this? Since it all happens deep in the bowels of LINQ, I can't even get any indication what field this is angry about.

I wrote the code below which calculates the length of a line on the form and save record. An error occurs when the programme tries to save the record. It gives me "Cannot perform '=' operation on System.Int32 and System.String" error. I checked the data type of "ID"(int), "Microscope"(Varchar), "Magnification"(int) and "Calibration"(Decimal), and they are fine so far as I know.
Code:
Private Sub btnEnd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnEnd.Click

Is it possible to extend primitive types such as System.String and System.Int32 (IE: integer) in .Net 4 and if so how?
To be more specific, I am aware of the concept of partial classes but this doesnt seem to be the answer. Also I find that System.String is not inheritable and Int32 is a structure.
Lastly I am interested in knowing both a VB.Net and C# answer to the above question.

I get an error "Cannot perform '=' operation on System.String and System.Int32" on the following code:
VB.Net Code:
Public Sub board2_OnGameWon(ByVal sender As Object, ByVal e As EventArgs)
If Not board2.isCheated() Then
Dim time As Integer = board2.getGameTime()' I have tried changing this to String
[code]....
The exception is in the lines where I 'Dim betterScores' above. The idea is that when the player wins a game their score is placed and held in the betterScore variable. It is then written to an xml file later on.
I have a Difficulty Menu item (System.Windows.Forms ToolStripMenuItem) containing 4 choices, 3 of them work but one doesn't. The one that doesn't work is "1.0 (Normal)" and in the Sub New is "adjustDifficulty(mnuDifficulty100)"I have copied some other subs that are associated with this code below.
VB.Net Code:
Public Sub New()
' This call is required by the Windows Form Designer.

I have buttons generated through code (dynamically). I have to associate an event (the same) to them. I use AddHandler button.click, AddressOf mysub.The issue is that mysub gets a string (mysub(string)), but AddressOf doesn't accept a parameter inside the routine. How can I do this? Using also an alternative to AddressOf.

1. I have three classes. Now I want to know how do I convert object to my class runtime?
for example,
Dim obj as New Object
obj = CType( MyPassedObject, Class1 )
Now, in above code, MyPassedObject can be Class1 or Class2 or Class3 but it is passed as Object. So is there any way that I can convert into CType as per the type of that object, directly to that class? I mean, I can pass object name into parameter and write down CASE statement here to convert to that class but I do not want to write down Case statement for each of my class, so just want to know is it possible anyway?
I mean just for example, Can I do something like obj = CType( MyPassedObject, GetObject('Class1') or any other way?
2. Now for this obj, I am getting properties runtime and setting values and then updating.
for example,
Dim PropertyInfo As Reflection.PropertyInfo() = obj.GetType.GetProperties()
Now, Will it work fine if obj has been declared as Object and then I typeCast it runtime and then I get properties and set its values. Will it work if obj's variable type is Object or it must be that class type itself.

I have two datetimepickers on my form to set a start date and end date for a SQL server database query. I am passing these dates with parameters to my query from the .Value of the datetimepickers. When I run the program, the code returns an error of "Conversion failed when converting datetime from character string" I am not converting anything in my code. It is my understanding that the StartDatePicker.Value is already a datetime and does not require conversion.
Here is some code:
'Define Wages_Query
Dim Wages_Query As String = _
"SELECT [Department], [Operation_NUM], sum(STWag) as [STwag], SUM(OTWag) as [OTWag]," & _
" SUM(Shift_Diff) as [Shift_Diff]," & _
" SUM(COALESCE(STWag,0) + COALESCE(OTWag,0) + COALESCE(Shift_Diff,0)) as [TotalWages]" & _
" FROM dbo.Financial" & _
