VS 2005 Schema .ini DateFormat - Program That Is Desinged To Read A 3rd Party Text File Database

I am having a problem with my program that is desinged to read a 3rd party text file database. I posted previosuly about a problem inserting an item in a new row and the column was expectig a different data type. It appears that sometimes the column is being determined to be of decimal value, I dont understand why. the fields contain information such as

Col1
F123456
CLW-12321 etc....

So my column fills with
123456
12321 the letters just get chopped off

So I added MaxScanRows = 0 to my schema file and that took care of the problem

Except now several of my columns that contain Date Values are coming back

9/24/2010 00:00:00

without the setting MaxScanRows = 0
The date returned 9/24/2010

Here is the code for my schema ini file I am creating:

HTML

Dim fs As New FileStream("Schema.ini", FileMode.Create, FileAccess.Write)
Dim writer As New StreamWriter(fs)
[CODE]............

I have been trying different settings hence the dimmed out lines

Here is the code to fill the datatable:

HTML

[CODE].............

I am thinking that without the MaxScanRows = 0 setting the datatype for Col1 is being incorrectly determined

I am not sure what is happening with other columns that contain date values. Apparently If i use MaxScan Rows=0 all columns are being pulled over as string value which creates numerous problems. If I dont use maxscanrows then all columns appear to be correct except Col21 MLSNUM which is being pulled in as a decimal. Can I change that in the schema file?
