I know to define integer type sqlparameter but I do not know the decimal type sqlparameter for the precession.
I am giving a sample example.
//Code
Dim sqlparameters(2) as sqlparameter
sqlparameters(0)=new sqlparameter ("@RMID", SqlDbtype.integer,7)
but in case of decimal I am giving like this
sqlparameters(1)=new sqlparameter ("@RMID", SqlDbtype.decimal,7,2)
which is wrong
What is the cleanest, most readable way to String.Format a decimal with the following criteria

In one of our application the parameters passed to a stored procedure in this way
Dim parm As New SqlParameter("searchText", SqlDbType.VarChar)
parm.Direction = ParameterDirection.Input
parm.Size = 50
parm.Value="test"
cmd.Parameters.Add(parm)
and the procedure contains a parameter as @searchText
ie the parameter name passed from the code is searchText and that in the stored procedure is @searchText .
But it is working properly, i am always getting the required results.
So my question is like so there is no need to specify @ before the parameter? Whether it will append @

My user requests to change the . on the numpad to a when entering text in a multiline textbox.So I was thinking about the KeyDown event.To determine if the numpad . was pressed I can do something like this [code]But now how do I change the returned charachter as a , ? All e.Key... properties are ReadOnly. The KeyPress events let me change this by providing e.KeyChar, but in that event I can't check for the numpad .
View 2 RepliesHow would I go about rounding up decimal numbers to the nearest 2 decimal places? For example $7.0000032 would be $7.01 In theory, VB would make it $7.00 but if it is > $7.00, I want it to reflect that to the nearest penny... so $3.0000001 would be $3.01

Is it casting from a double to a decimal implicitly. How would I do this explicitly in vb.net?
1) One Decimal Varibale stores a decimal value
2) The value must be converted in string ( some time the comma is used as decimalplaceholder some time the dot)
3) the user modifies the value
4) i need to riconvert the string back in decimal
how can i do this
so:

View 3 RepliesMaybe this is just a really basic question that everyone knows the answer to, and is why I couldn't find the answer. What I want to do is pretty simple. I want to declare a custom type that's just like a Single, except when you access the value, you get the value rounded to the second or third decimal place. Something like this:

Problem: Using the sub routing below, when adding a value to another value the results eventually change from 2-decimal places to multiple decimal places.Basically, the amount stored should always only be 2 decimal places, because the values passed in are always 2 decimal places. Output from calling the sub routine multiple times.
Running total = 329430.75
New Withheld Amount = 710.79
Running total = 330141.54
[code]....
As a workaround, I have a new routine that uses a custom round function to properly store only 2 decimal places - as the VB round function does not perform the type of rounding desired.I understand that we are removing the value from the dictionary and adding it back..
format number to hower many number on left of decimal and 1 decimal without rounding
