I import a XML to a Dataset and works fine, import XML with Schema and fine to, but for any estrange reason the primary key that is in the XSD don't appears in the Dataset.

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?

I'm using Visual Studio 2008 and MS Access 2007.
I have linked the database to vs2008.
The first problem I have now is how to add all the data to the combobox from access 2007? [I have solved this myself accidentally.]
The second problem I have is I cannot save the primary key.
Assume that I have these:
Table name: tCustomer
Fields:
ID Datatype [Text]
[Code]....
Now, the user fills in the form. The ID cannot be edited by them where it's automatically counts the number of customer in database and give the id. For example, I already have 3 customers in the database so when I add new Customer, it will be 4 for the ID.
When I click save, it shows me the message of "Index or primary key cannot contain a Null value." I have set an input mask for my Customer. So, can I make it to save in a format like CT001, CT002, CT003 automatically?
On a client i have an anonymous list containing a multi-column primary key previously selected from the DB.Then i need to select all the records from the DB that equals the primary key list i have stored in the memory.[code]

I have an .XSD that is made from a class so that I can pass to a webservice. It got it over to the webservice as an XMLSchema object and now I need to make it into a class so that I can make objects out of it on the webservice side. I know that XSD.exe is the answer but I'll be darned if I can puzzle out exactly how to implement this thing. I need it to do this conversion at run time so I need to put the code for it into my project and all the references I've seen to using XSD.exe talk about calling it from the command line.

There is an old timesheet application being used in my company and i am going to rewrite it in asp.net.There are other tables which can be linked to new Timesheet table like employee table but my main concern here is the Project and Project_Activity table.In the current system, there is a one project and a activity table which are linked to the timesheet table seperatly and user has to spend alot of time on selecting activities code they worked on for specific project.I have came up with the new idea; Project manager will have to fill up a project template and link all the activities code with the one project before starting this project. This way user will have to select the project only and it will automatically bring the associate codes for them.I like to know if this design will work okay? and is it okay to link Project_Activity table with timesheet?

return dsRetVal

On the client side I call this function through a generated "service reference":
Dim ds as Reference1.MyTypedDS = myRefInst.GetDS
How can I disable schema serializaion of the typed dataset to reduce the traffic?Is it enough to set the SchemaSerializationMode of 'dsRetVal' to ExcludeSchema before returning it? Or is this option ignored by WCF?
