Solution 1

Its the same problem as here:

Input string was not in a correct format.[^]

Look at the two lines above it, notice the 500 thats missing? You need to supply that integer value on those ones too.

HI Ron..on declaring the application date how do i declare date like yr/month/date with also same command here cmd.Parameters("@date").Value = date??

Ron Beyer 5-Jun-13 21:49pm

Yes, as long as date is a DateTime then the parameter will infer the type of the parameter when it creates it.

ok im wondering what do you mean in my statement of 500?? i believe that my size of the value for package and promocode also with other value i comment out.. do i need to remove it that's what i think on what you've said earlier

No, what I'm saying is that there is no overload of the .Add function that takes (ParameterName, SqlDbType, ColumnName). Its trying to convert it because the closest overload is .Add(ParameterName, SqlDbType, int32). Its trying to convert your string to the int32 parameter. See the linked question in my answer for links to the MSDN documentation for the .Add function.

BTW, this is a really horrible "feature" of VB.NET, implicit type conversion between unrelated types. In C# this would cause a very apparent compile-time error.

Solution 2

Putting the variable applicationdate in quotes like this "applicationdate" causes VB.NET to treat it like a string. If it's a variable, don't use quotes.
