DataTable In SQL Server Compact Exception On First Fill ONLY?
Jun 5, 2011
I'm trying to create a Server/Client Sync scenario for my application using Sync Services for ADO.NET specifically the LocalCache custom tool which sets the whole thing up for me.My server DB has 5 Tables, all of which are being synchronized to the client application, which now has a SQL Server Compact DB with the same schema as the server DB. I have a dataset with some custom queries that I use to connect my app with the local database.So far so good.However in my application when I try to fill one of my tables with the table adapter on my form (the default "fill" method) it gives me the following exception:No mapping exists from DbType Object to a known SqlDbType.
However, if I continue and do the fill again, IT WORKS without a problem.
Try
Me.WTSUsersTableAdapter.Fill(Me.WTSMainDataSet.WTSUsers)

I am trying to add NewRow to the database by using datatable in dataset, but before I do that I want to make sure that row is not already there. I create new row for the datatable I am working with, fill it with information. I fill datatable with the row from database that has the same primary key as my NewRow by using tableadapter.fill method, but when I do that my NewRow that was never added to the datatable is filled with information from database(and not information that I assigned to it). I count rows in my datatable before I fill it and it's 0, so why is my NewRow affected by Fill command? (I am using VB.NET 2005 Framework 2.0)

I have an internet available SQL Server 2008 R2 instance that is running normally. Clients connect over the internet from vs 2005 and 2010 desktop applications, without issue. My scan gun application can connect to the local instance (if I'm in my office) but not to the internet instance from my Windows Mobile 5.0 scanning device. Connect string = user id=[Code]. This connection string works fine for the desktop apps. It's not a port issue, I have all the correct ports open.

So I created a table and one of the columns is is called currencydate, and has a datetime data type. Within my vb scripts, i've taken a filename and extracted the date components from it. an example filename is WER22402.10. The part in bold is the date meaning 24th February 2010.
I use the following function to extract the date values and convert it to a date type.
Private Function ConvertStringToDate(ByRef FileName) As Date
Dim S As String = FileName
S = S.Substring(4, 7)

I am trying to build a stand alone programe in VB.net (Most of my Experience is in VBA) I am using Visual Studio 2008 and have created as part of my project an SQL Server Compact database (Database1.sdf)
The problem I am having is that I can not seem to work out how to connect to this database and retrieve the data into a recordset to work on. I am sure it must be a simple task but I can not get it to work.
I have tried two ways, first is via ADODB connection
Dim strsql As String
Dim rsRecord As New ADODB.Recordset
Dim ConsDataADODB As New ADODB.Connection

I am trying to do multiple joins within a single query in SQL Server CE. I know that SQL Server CE doesn't support multiple SELECTs but I can't find any information on multiple INNER JOINs. I keep getting token errors on ProjectItemMaster (after the FROM) and the first INNER JOIN. Warning this is a big ugly query used to generate reports.
[Code]...
If I can't uses multiple INNER JOINs I can I break the query down into a number of different queries but I would prefer not to. So it is easier to maintain a SQL Server CE and an SQL Server version of the program.

Greetings, I'm a little bit confused about SQL Server Compact behavior.I have a small app that uses a small sdf file located on a network share.The problem is that while the app itself is working perfectly well using the connection string that points the location of the sdf file on a network drive, when I try to open the same sdf using the Server Explorer I get this error:
SQL Server Compact does not support opening database files on a network share.Obviously, if the app IS working it does indeed support network shares, then why Server Explorer cannot open it?
I copied the database file to a local drive but it's not very convenient. What might be the problem?

I have an application that is currently using DAO and would like to move it to ADO.Net. The problem I'm having is that when I do, I cannot do any queries that take variables if the database is Access or SQL Server Compact Edition. For example: SELECT RecipeName FROM tblMasterRecipe WHERE CategoryID = iCategoryID..The database is a local standalone database. Of course if I use the Standard SQL Server I can add parameters just fine using the TableAdapter Query Configuration Wizard. How do I do something similar for Access or SQL Server Compact Edition? The Create new stored procedure radio button is greayed out when the database is Access or SQL Server Compact Edition.

I am reading an XLSX that is about 100MB in size using the following (on XP 32bit):
connS = "Provider=Microsoft.ACE.OLEDB.12.0;"
connS &= "Data Source=inwaredata" & frmConversion.DBCompany & "" & in_file & ";"
connS &= "Extended Properties=""Excel 12.0 Xml;HDR=No;"""
[code]....
On the FILL command the memory in the task manager gets up to about 1.3GB and then gets an outofmemory exception. Is there a way i can specify this is read-only and read-forward since i am just reading through the XLSX and not moving backwards/forwards or doing any updates? Or, is there a better way to read the XLSX so i don't have to do a file.I do not want to use the excel add-on - i just want to read straight through the XLSX file, massage the data i read and then write it to an SQL database.

i want to fill a Datatable with a Datareader row by row but get an exception because the reader's columns have a different order than the Datatable's columns.
Why and how does a Datatable loads itself with a Datareader correctly, even so it has a column collection with different order?
I need to calculate values for every row so i dont want to load the Datatable completely but row for row. It has 25 columns so i dont want to set it all manually.
There must be a chance to load/fill/add a new row from a datareader without having the same column order(reader.GetSchemaTable?).
Following is what i have but what doesnt work:
Using reader As System.Data.SqlClient.SqlDataReader = command.ExecuteReader
'next line works(configInfo.DataSource is a Datatable)but is inappropriate
configInfo.DataSource.Load(reader)

I am using a SQL query to fill a datatable from 2 associated tables. The first table has Products and the second has associated addonpackages. When I loop through my Products I am able to get all of the addonpackages for the first product but after that the datatable is only getting populated with the last addonpackage for each product. ie:
product 1 - all 6 packages are added tp the datatable
product 2 - only package 6 is added to the datatable
product 3 - only package 6 is added to the datatable
...and so on
My query follows. Why I am getting all of the info for the first product but just the last item for all others. No matter which product I would query first, I get all of the associated data with it but only the last for all others.
SELECT Products.ProductNumber, Products.Name, Products.Mnemonic, AddOnPackages.PackageNumber,
AddOnPackages.Name AS PackName, AddOnPackages.Mnemonic AS PackMnem
FROM AddOnPackages RIGHT OUTER JOIN
Products ON AddOnPackages.ProductNumber = Products.ProductNumber
WHERE (Products.Name = @ProdName)
ORDER BY Products.ProductNumber, AddOnPackages.PackageNumber

I would like the main form I am designing in VB.net to appear as quickly as possible. As a result I don't want to fill a datatable in the load event but instead fill it as soon as the form appears, in the background.Then when a user clicks the button a listbox can quickly be populated.
With this in mind I called a function to fill the datable from the _Shown event. The trouble is that the form freezes until the query executes, making the process pointless for my needs.
Does anyone know how to keep the form active while the datatable fills silently in the background?
