Currently, I have a WinCE application which uses the System.Data from NetCF and System.Data.SqlserverCE from MSSQL Server 2005 Mobile Edition. Now, I'm trying to use the System.Data.Sqlclient but I can't seem to find it in my System.Data. I notice that there are different version which is one from NetCF and one from the MS.Net framework itself.
Here's my question: Is it possible for me to use both System.Data? or should I only choose one. This is for my attempt to connect also from an SQLServer and connect to the local SQLServerCE as well.
I have created a windows library control that accesses a local sql database
I tried the following strings for connecting
Dim connectionString As String = "Data Source=localhostSQLEXPRESS;Initial Catalog=TimeSheet;Trusted_Connection = true"
Dim connectionString As String = "Data Source=localhostSQLEXPRESS;Initial Catalog=TimeSheet;Integrated Security=SSPI"
I am not running the webpage in a virtual directory but in
C:Inetpubwwwrootusercontrol
and I have a simple index.html that tries to read from an sql db but throws
the error
System.Security.SecurityException: Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. at System.Security.CodeAccessSecurityEngine.Check(Object demand, StackCrawlMark& stackMark, Boolean isPermSet) at System.Security.PermissionSet.Demand() at System.Data.Common.DbConnectionOptions.DemandPermission() at System.Data.SqlClient.SqlConnection.PermissionDemand() at System.Data.SqlClient.SqlConnectionFactory.PermissionDemand(DbConnection outerConnection) at System.Data.ProviderBase.DbConnectionClosed.OpenConnection(DbConnection outerConnection,

I think that a windows form connecting to a sql database running in a webpage should be simple
conn.Open(); . Everything works fine when I run it from my computer. When I try to run it from a network share I get the following error,

I am using Visual Studio 2005 and .Net framwork v2.0.50727.

Hey All, I am developing a data acquistion system which monitors the amount of energy that a user consumes in different parts of a house and displays the information in real time on their computer screen. I am collecting the data through tranducers attached to the circuit breakers in the breaker box and sending the data to analog-to-digital converter channels in a MCU. I am retrieving the data from the serial port and storing it to a text file. Each line of data in the text file represents three fields which are separated by commas. I will be reading data from multiple data collection boxes so the first field is the unit number, the second fied represents the analog-to-digital converter channel number from each unit, and the third field is the data that is collected from the ATD channel. I am trying to use SSE to retrieve the data from the text file, and parse each line of data into individual columns in a databse. Then I want to be able to extract the data associated with a particular ATD channel number from the databse and display it in the appropriate text field on a windows form. I've got the MCU programmed. I have no problem collecting the data from the serial port, and I can do the visual basic programming okay. I have absolutely no clue how to read the data into the database, continuosly read new values into the databse, and then access the stored data to update the text fields on the form. Please help if you can, I've been working on this specific problem for a couple of weeks and I'm not making any progress. Thanks.
i someone had teach me how to write a query in datatable. however i need to get the data out from my database rather than the data table. can someone teach me how should i do it?esp at the first like.... like DataTable dt = GetFilledTable() since i already have set of data in my preset table i should be getting data from SqlDataSource1 right ( however i am writing this in my background code or within <script></script> so can anyone help me? protected void lnkRadius_Click(object sender, EventArgs e) { DataTable dt = GetFilledTable(); double radius = Convert.ToDouble(txtRadius.Text); decimal checkX = (decimal)dt.Rows[0]["Latitude"]; decimal checkY = (decimal)dt.Rows[0]["Longitude"]; // expect dt[0] to pass - as this is our check point // We use for rather than fopreach because the later does not allow DELETE during loop execution for(int index=0; index < dt.Rows.Count; index++) { DataRow dr = dt.Rows[index]; decimal testX = (decimal)dr["Latitude"]; decimal testY = (decimal)dr["Longitude"]; double testXzeroed = Convert.ToDouble(testX -= checkX); double testYzeroed = Convert.ToDouble(testY -= checkY); double distance = Math.Sqrt((testXzeroed * testXzeroed) + (testYzeroed * testYzeroed)); // mark for delete (not allowed in a foreach - so we use "for") if (distance > radius) dr.Delete(); } // accept deletes dt.AcceptChanges(); GridView1.DataSource = dt.DefaultView; GridView1.DataBind(); }
i have installed visual express and sql express. but the problem is i want to add the connection string manuallty in visual studio express 2005. so i want to add a reference of sql.data.sqlclient but could not add ? i am not sure what is the problem or is am i missing anything
I am not able to add the namespace "system.data.SqlClient" and not able to get the intellisense for sqlconnections. I have only vs2005. i do not have sql management express or sql server 2005
I've been given the task of moving data from an old system to a new one. That's easy enough apart from some of the data fields do not match in the least:
Example: In the old system (tableOld) there is a field that contains text data such as 'Laboratory','Field','Market','Demo','Development', but this one field could contain one or more of these. In the new system (tableNew) there are boolean fields for each of the above.
What I need is a way to check for these and then make sure the correct field(s) gets ticked (1 entered into the field) in the new system.
Any suggestions, just trying to get my head around SSIS.

Do i have to use System.Data.SqlServerCe or System.Data.SqlClient to connect to my db.
my environment: VS2005, SQLExpress with SP1, WXP with SPs, the error msg I get is: 'System.Data.DataRowView' does not contain a property with the name 'change'. The base for all this is the 'MS Club Site' sample code downloaded from ASP.NET! After adding a new data field "change" to my DB I changed the StoredProcedure "PagedUpcommingEventList" (statement 31) and in the 'Repeater' I added statement 32 to reflect this change (see code below). When calling 'Configure Data Source' on the SQLDataSource I can read the DB (using the StoredProcedure) but I never see the new field 'change'! I certainly checked for additional StoredProcedures with the same name: "PagedUpcommingEventList" --- I definitely have only one in my project.PS: In another .aspx file using a SQLDataSource with a DataGrid; the field is showing up correctly! I spent days in the area of 'caching' without any success; thought the StoredProcedure is always called from the 'cache'! ....

I am new to SS7. We are planning to rearrange our system databases so that the logs are on one drive and the data files are on a different drive. I found a really good white paper on this but just want to verify that there is not a problem with doing this. In sybase there were some restrictions on doing this. Any info you have would be appreciated.
Hi, I am using the DTS tool to Copy tables/date form AS400 files to Sql2005. When I enter the query select * from tableas4000 then I can see all the rows, the statement is parsed in the next step I get the error " An error occured which the SQL Server Integration services wizard was not prepared to handle. No error message available,result code:DB_E_CANTCANCEL(0*80040E15).(System.Data)".
How do I solve this? I am using IBMDB2 UDBFOR ISEREIS IBMDA400 OLE DB PROVIDER.
new to SQL Server 2000. We have an obsolete database that we need tosave off for x number of years. DB2 has utilities (DB2Look/Export)that allows for the export of the data along with a schema and scriptthat enables the future recreation of the structure of the databasesand tables to include RI etc. You can save off the architecture andrelationships of the tables as well as the data.Does SQL Server have anything similar?Thanks in advance.Gerry
I believe I've encountered a compatability problems with Visual Studion CF 2, specifically with the System.Data.SQLServerCE reference when trying to run (in debug mode - Pocket PC 2003 emulation). The environment is configured as follows:
Visual Studio 2005 - Compact Framework 2.0.50727
Microsoft SQL Server 2005 Mobile Edition
The (VB) project includes the following references:
System.Data.dll V2.0.000 from Program FilesMicrosoft Visual Studio 8Smart DevicesSDKCompact Framework2.0V2.0WindowsCE
System.Data.SqlServerCE.dll V3.0.5214.0 from Program FilesMicrosoft SQL Server Mobile EditionDeviceMobileV3.0
The IDE does not sense any problems with the following code until I try to run it in debug mode using the Pocket PC 2003 emulator. The code :
Imports System

Dim strConn As String = "Data Source = Test.sdf; Password = <password>"
In the debugger, the program terminates at Dim CEEngine As New SqlCeEngine(strConn). The message displayed is
Can't find PInvode DLL 'sqlceme30.dll'
I've tried referencing a different version of System.Data.SqlServerCE.dll (from Program FilesMicrosoft SQL Server90ToolsBinnVSShellCommon7IDE but the program will not even deploy to the emulator with this reference.
I encounter a Deployment/and or registration failed wit error : 0x8973190e - There is not enough space on the disk.
I've inherited a .NET CF 2.0 application at work that uses SQL CE, and as I'm digging into the build process, I'm getting confused about which version of SQL CE that is being used.
The project references System.Data.SqlServerCe (no hint path, just from wherever VS 2005 has it). When I look at the assembly in my project, the version shows up as 3.0.3600.0, but when I browse to the DLL's location on my hard drive (C:Program Files (x86)Microsoft Visual Studio 8SmartDevicesSDK\SQL ServerMobilev3.0System.Data.SqlServerCe.dll), right click the DLL and check the properties, the version shows up as 3.0.3600.0.
In our installation package, we install three SQL CE Cabs: sqlce30.dev.ENU.ppc.wce5.armv4i.CAB sqlce30.ppc.wce5.armv4i.CAB sqlce30.repl.ppc.wce5.armv4i.CAB
When installed on the device, the Remove Programs dialog shows as "Microsoft SQL Mobile 2005..." is installed. We keep the cabs in a seperate location so they are not just pulled from anywhere on the hard drive.
However, when I install the same CAB files located at: C:Program Files (x86)Microsoft Visual Studio 8SmartDevicesSDKSQL ServerMobilev3.0wce500armv4i, the device shows "Microsoft SQL Mobile 2005 Compa...." is installed.
In my Add References dialog, System.Data.SqlServerCe has version 3.0.3600.0, runtime v2.0.50727
Some questions: 1. Is the version 3.0.3600.0 the same between 3.0 and 3.1? 2. Given a System.Data.SqlServerCe DLL, how can I tell if it is the 3.0 or 3.1 version? 3. When upgrading my project to use 3.1, is it enough simply to upgrade my build environment? Or should I need to change the references in my project? (It appears that the 3.1 DLLs have been placed into the default locations where VS 2005 is pulling them from). I'm using VS 2005 SP1 on Vista x64.
Here's a new one I came across that stumped me for a bit. DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'xxxx'. It appears that one of my dropdown menus was referencing the old SqlDataSource1for its data source id. I had already changed the name of the of the id to something else though. To fix it, I just updated the reference to the new name.
How do I get a System Table like 'Sysobjects' into the Data Access Layer? My app generates tables on the fly, and has to check in the sysobjects table which tables are present.
