I have been wracking my brain trying to figure out how to get OleDB to not import empty rows in my importable excel files.  It starts and will run perfectly fine until it hits an empty row and then it craps out.  Is there some way of doing this where if the row it is encountering it goes to the next row?  I am using a foreach loop.  The loop code looks like this:

                {
                    File.Copy(ExcelTempl, ExcelFile);
                    DirectoryInfo di = new DirectoryInfo(DropZone);
                    FileInfo[] fi = di.GetFiles("Master_*.xl*");
                    // step through each found file 
                    foreach (FileInfo fiTemp in fi)
                    {
                        {
                            // Connection String to Excel Workbooks
                            System.Threading.Thread.Sleep(1000);
                            string excelConnStr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source='" + DropZone + "\\" + fiTemp + "'; Extended Properties=\"Excel 8.0; HDR=YES; IMEX=1;\"";
                            WriteEvent("File Read", "Reading excel file " + fiTemp + " now.", "Automation User");
                            using (OleDbConnection connection = new OleDbConnection(excelConnStr))
                            {
                                connection.Open();
                                DataTable dt = connection.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
                                if (dt != null)
                                {
                                    string[] excelSheets = new String[dt.Rows.Count];
                                    int i = 0;
                                    foreach (DataRow row in dt.Rows)
                                    { // I believe I need to do something right here

Any suggestions would be appreciated!

I use new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=uploadedfile;Extended Properties=""Excel 8.0;HDR=NO;IMEX=1""");to process uploaded excel file, however I got  The 'Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine error on production machine.

hi, 

I have a simple search function which takes the users input and checks this against a field in my database, however i would like the search to check 2 fields in the database table.

When i have only one field the sql command works fine, however when i add the second field to teh sql command i get an error of "No value given for one or more required parameters." when attempting a search.

My code is as follows;

<asp:SqlDataSource ID="SqlSearch" runat="server" ConnectionString="<%$ ConnectionStrings:#######Data %>" ProviderName="<%$ ConnectionStrings:########.ProviderName %>" SelectCommand="SELECT [ID], [PartNo], [Description], [Category] FROM [Items] WHERE (Description LIKE  '%' + ? + '%') OR (Category LIKE '%' + ? + '%') AND ([ShowOnSite] = true)"><SelectParameters><asp:ControlParameter ControlID="Search" Name="Description" PropertyName="Text" Type="String" /></SelectParameters>

So i would like sql command to search both the description and category fields, would this be possible? 

Thanks 

What I am trying to do using ASP>NET VB is create a new record when redirecting to another screen.  The purpose of this is to save values.  View state works OK but it requires using the back button.  I guess I could use Session State but there are many. Also, I want to use an AJAX update panel, so view state controls do not seem to work.

I already have code that saves a new record.  I also have code that retrieves a record using the click even with a list control.

My idea would be when returning to the original screen to use the form load event to call a sub that would open a specific record in the database.  This would be the record that was saved when last leaving the screen. Where I am stuck is I cannot learn how to open a data record except by using the list box.

Any ideas?

I have a query that needs data from 3 different datasets.

Here's the code I have so far:

Dim Conn1 As New MySqlConnection(ConfigurationManager.ConnectionStrings("MYSQLConn1").ConnectionString)
Dim Conn2 As New MySqlConnection(ConfigurationManager.ConnectionStrings("MYSQLConn2").ConnectionString)

Conn1.Open()
Conn2.Open()

Dim query As String = "select distinct `number`from db1.numbers e where e.customer = 32"
Dim query2 As String = "select `number` from db2.numbers where CustomerID = 32"
Dim query3 As String = "select `number` from db2.numbers2"

DATASET1 = New MySqlCommand(query, Conn2).ExecuteReader
DATASET2 = New MySqlCommand(query2, Conn1).ExecuteReader

Results2 = New DataTable
Results2.Load(DATASET2)

Conn1.Close()
Conn2.Open()

DATASET3 = New MySqlCommand(query3, Conn1).ExecuteReader

Results = New DataTable
Results.Load(DATASET1)

Results3 = New DataTable
Results3.Load(DATASET2)

Conn1.Close()
Conn2.Close()

Here's the query that I need it to work using the results from the above 3 datasets:

select distinct `number`
IF(`number` in (select `number` from DATASET2), 1, 0) as 'status' 
from DATASET1 e 
where number like '0744%' 
and customer = 1
AND `number` not in (select `number` from DATASET3) 
order by status desc;

Q: How can I make the above query work having these datasets?

Forgive me if this is in the wrong place but I figure I would ask here anyway.  I am using OleDB to read records from Excel.  The crazy thing is it was working properly for the longest.  Now all of a sudden, it takes my records and duplicates them.  To rule out code related issues, I tried a test on an excel with only one record.  That one was fine.  So I figured after my reboot the problem was resolved. It is not.  I simply do not get what the problem is because it does not always do this.  It is at random.

Hi All,I am new gem for developing MVC application's. I created an MVC 4 application using VS 2013.

In oracle I have one table as SSO having two columns as SSOID and SSONUM.

I created one Procedure to get data on the basis of requested ID.

CREATE OR REPLACE PROCEDURE GETSSODETAILS (
cursorParameter OUT SYS_REFCURSOR,
p_ssoid IN SSO.SSOID%TYPE
)
as
SSONum SSO.SSOnum%TYPE;
SSOid SSO.SSOid%TYPE;
cursor CursorParam is
SELECT * FROM SSO WHERE SSOID=p_ssoid;
BEGIN
  OPEN cursorParam;
  if cursorParam%ISOPEN THEN
  FETch cursorParam into SSONum, SSOid;
  dbms_output.put_LINE('SSONum = ' || SSONum || ' SSOid = ' || SSOid);
  END IF;  
END;

Now I added ADO .Net ENtity Model Framework in my project to work with Db Context.

After that In HomeController.cs class i have below code :

public ActionResult Index()        
        {
            Entities entities = new Entities();
            var output = entities.GETSSODETAILS(1);           
            return View(output);
        }

Which makes a call to my Model1.context.cs and there I have code as below

public virtual ObjectResult<SSODetails> GETSSODETAILS( Nullable<decimal> p_SSOID)
        {
            var p_SSOIDParameter = p_SSOID.HasValue ?
                new ObjectParameter("P_SSOID", p_SSOID) :
                new ObjectParameter("P_SSOID", typeof(decimal));
            return ((IObjectContextAdapter)this).ObjectContext.ExecuteFunction<SSODetails>("GETSSODETAILS", p_SSOIDParameter);
        }

When I am running this code, It gives me error as below

ORA-06550: line 1, column 8:
PLS-00306: wrong number or types of arguments in call to 'GETSSODETAILS'
ORA-06550: line 1, column 8:
PL/SQL: Statement ignored

Please let me know Am I doing something wrong..?? I believe I have to pass one more parameter in my Model1.context.cs function while calling ExecuteFunction() method. and that should be output parameter. I am not able to declare output parameter which works with CURSOR type in Oracle.

Spent my last four days on this. Would be great if anyone can help me asap. I have deadlines to kick off my project.

I will be lucky if someone can send dummy project for the same requirements. VS 2013, using Oracle Database with the help of ODP .Net using ENtityFramework, Calling procedure.

Thanks

I have a .NET 4.5 website that uses mysql-connector-odbc-5.1.6-winx64 to communicate with a MySQL 5.5.30(Linux) server. When my host upgraded to Microsoft Windows 2012(IIS 8.5) a difficult bug emerge. This is what the Exception log said :
