Failed To Convert Parameter Value From String To Int32
Jan 28, 2011I'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.

VS 2008 - Failed To Convert Parameter Value From String To Int32
Jun 5, 2010I 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!

Formatting - How To Convert Decimal To String
Apr 14, 2009I have an app that deals with currency. For display purposes I use the nifty VB FormatCurrency function which will format based on the OS's region setting. So, if in France you might get 123,45 where in the US you would get 123.45. To perform calculation on these amounts I use CDec() to convert to decimal.
My problem is that when I convert the Decimal to a String using toString() it formats according to the currently set region. I need to be able to always convert the decimal into a String representation for the US, i.e. with decimal points. I thought I would be able to do something similar to this:
.toString("#0.00")
Stuck Trying To Convert A String To Decimal?
Aug 1, 2009i'm a little stuck with a personal project, i'm interfacing a MiniBee usb output card to my pc and having a few code problems, i am trying to control outputs 1 to 8 which requires a decimal number that relates to the binary pattern of the ouputs if that makes sense i.e
1 = output 1 on
2 = output 2 on
3= output 1 and 2 on
etc etc
So, i figured the easiest way to individually control outputs was to use public boolean vars Out1 to Out8 so i can use those anywhere in the code and use a form timer to trigger the updating of the output
So the bit im stuck on is i've done a test using 8 checkboxes to set Out 1-8 as true/false

Convert String To Integer With Variable Decimal Sign?
Nov 22, 2011I am currently looking into the conversion of a string value to an integer. Obviously I will need to do some validation as to whether the passed value is in fact convertible to an integer.
At the heart of my question is this: the users' local is nl-BE (dutch (Belgium)), which means that we use a comma as decimal sign (and points as thousands separator); e.g. 123.456,78 would be a valid nl-BE number. Now, when using the numeric keypad, the
decimal key will yield a point, not a comma (weird huh!). So many user will enter 123456.12 and when converted to an Int, this should yield 123456.
The thing is that I want to cover all possible angles; both points and commas may be used as decimal sign by the users. So I wondering if anyone has written some code that deals with such a situation. I was thinking of an extension method that makes the
conversion based on whether a point or a comma is last used in the passed string (since no thousands separators should occur after the decimal sign).

View 1 RepliesConvert BCD To Decimal?
Dec 7, 2009I am trying to convert information stored in a file to a decimal (or ASCII) format, then write the contents of that file to a new file.
What I have is a list of files that are generated from a cash register. The documentation that was provided to me says that this particular file I am trying to work with has a length of 6, a width of 6, and that it's BCD type.
I've done quite a few google searches and can't seem to find a good solution. I know BCD numbers should be stored as 0000 format. But the problem I'm getting is when I read each part of the file (using my sr.read) I'm getting full numbers..and I am expecting the 0000 format. I'll get a 0, 0, 0, and then all of the sudden I"ll get a number that's 65,000..then I'll get a 34...and there doesn't seem to be any
I'm sure I'm doing something incorrect here, my knowledge of reading HEX, BCD, etc. is very minimal. I'm guessing it has to do with using a filestream, so I can use the fs.ReadByte() method..but when I tried that my program was literally chugging along for several minutes with no sign of ending.[code]...

View 8 RepliesConvert A Double X To A Decimal Y?
Oct 5, 2011Let's say I want to convert a Double x to a Decimal y. There's a lot of ways to do that:
1. var y = Convert.ToDecimal(x); // Dim y = Convert.ToDecimal(x)
2. var y = new Decimal(x); // Dim y = new Decimal(x)
3. var y = (decimal)x; // Dim y = CType(x, Decimal)
4. -- no C# equivalent -- // Dim y = CDec(x)
Functionally, all of the above do the same thing (as far as I can tell). Other than personal taste and style, is there a particular reason to choose one option over the other?
EDIT: This is the IL generated by compiling the three C# options in a Release configuration:
1. call valuetype [mscorlib]System.Decimal [mscorlib]System.Convert::ToDecimal(float64)
--> which calls System.Decimal::op_Explicit(float64)
