SAP.Middleware.Connector.RfcInvalidParameterException: Table line 0 out of range: table is empty

I have a C# console aplication that connects to a SAP server to get data from some of its tables.
Sometimes this error pops up when i try to copy a value from a field in a SAP table called "SOHEADER" to a string variable.
Here's the stack trace:
SAP.Middleware.Connector.RfcInvalidParameterException: Table line 0

Can somebodoy tell me what could be the issue here? Could it be that the field comes empty from the SAP table and if i try to copy it somewhere the whole thing crashes? Is there a safe way to check if the field is null before trying to copy it?

in your line
status_doc = Convert.ToString(tableHstatus[0].GetValue("GBSTK")).ToUpper();
you are adressing the IRfcTable tableHstatus with index 0, which means you're trying to read the first entry from that table object. That only works if the table has entries. You should first check whether the table contains any rows and only then continue. After invoking the RFC function, check property RowCount of your IRfcTable.
functionStatus.Invoke(rfcDest);
if (tableHstatus.RowCount > 0) {
status_doc = Convert.ToString(tableHstatus[0].GetValue("GBSTK")).ToUpper();
}
there's a number of reasons why a RFC function might return an empty table. It could be standard behavior in some cases, or it could be because some query parameter was wrong and no data was found, or because an error occurred in the function. Standard SAP BAPIs usually return a status structure or table (often of type BAPIRETURN or BAPIRET2) that contains additional information about error codes, messages etc.

how can I add or update values with select count (*) and parameters SQL table and c#?

I'm trying to update information in the SQL table with this code using c# language, the first section is to count all data. the second section is to run my update Query/function
the event is : private void mlnk_ADD_Click(object sender, EventArgs e)
string SARL;
SqlCommand cmd = new SqlCommand("SELECT COUNT(*) FROM [employe] WHERE CODE = #CODE OR FULLNAME =

cmd.Parameters.Clear();
cmd.Parameters.AddWithValue("#CODE", mtb_CODE.Text);
cmd.Parameters.AddWithValue("#FULLNAME", mtb_FULLNAME.Text);
cmd.Parameters.AddWithValue("#BIRTHDATE", mdtp_BIRTHDATE.Text);
cmd.Parameters.AddWithValue("#BIRTHPLACE", mtb_BIRTHPLACE.Text);
cmd.Parameters.AddWithValue("#ADDRESS", mtb_ADDRESS.Text);
cmd.Parameters.AddWithValue("#NCCP", mtb_NCCP.Text);
cmd.Parameters.AddWithValue("#PHONE", mtb_PHONE.Text);
cmd.Parameters.AddWithValue("#JOB", mtb_JOB.Text);
if (mrb_LOCATERR.Checked == true)
{ SARL = "LOCA-TERR"; }
if (mrb_LUDAR.Checked == true)
{ SARL = "LUDAR"; }
if (mrb_ECORA.Checked == true)
{ SARL = "ECORA"; }
cmd.Parameters.AddWithValue("#SARL", SARL);
int UserExist = (int)cmd.ExecuteScalar();
here I am trying to insert the data into my table after checking that all data not exist to avoid the duplicate
if (UserExist > 0)
{
this.Alert("the information already exists.", frmAlert.alertTypeEnum.Error);
}
else
{

}

Use stored procedure its more cleanner and you can define the output and the input parameteres ( exemple :select cout(*) into output_parameter where ....).
and use switch statement, There is a lot of IF in your code.

I have a scenario I am unable to understand, regarding the session variables

Note:-The Question pertains to ASP.NET and C#.
I have 3 functions
GetDataBySearchCriteria.
GetData.
GetGridData.
The first function is called when page is loaded. The second function gets called when the user makes a change on page and and presses a btn (GetData) where I set the Session Variable which holds the Search Criteria Data as GridData Object. The Third function is called by the second function to get data as a GridData Object where GridData is a user defined class. Later in the calling function it is converted to json object which is used to render a grid table(jqgrid).
Problem:- We maintain the session in order to facilitate a temporary search criteria holder which we use when the intended user navigates from one page to another in the same module. In my code I set the Session variable only when user presses GetData and according to the current requirement I had to put hard code changes to change the data I get from session for particular pages. In doing so the Session Data is automatically changing. I am unable to figure out why. please help.
Here's the code :-
[System.Web.Services.WebMethod]
public static string GetDataBySearchCriteria(int ReportID) // called when page is loaded
{
if (SessionVariables.RoleID == 0)

When you do
gd = HttpContext.Current.Session["SalesUserSession"] as GridData;
gd is an Object reference to HttpContext.Current.Session["SalesUserSession"]
that's why your session is impacted by your modifications.

Search multiple column using multiple control in asp.net using linq

Project_Detail pro = new Project_Detail();
string title=Ttitle.Text;

string key = Tkeywrds.Text;
string area = Ddl_area.Text;
string categ = Ddl_catgry.Text;

var q = from obj in da.Project_Details
where obj.Project_Title.Contains(title)

|| obj.Project_Area.Contains(area)
|| obj.Project_Category.Contains(categ)

|| obj.Project_Type.Contains(type)
select obj;
if (q != null)
{
DetailsView1.DataSource = q;
DetailsView1.DataBind();
}
else
{
Literal1.Text = "Data not found";
}
this code give last record of table and also not give else condition result.
I want result of all condition and want to use LIke satatement.

q is never null. It might be empty, though. So you should change your code to
if (q.Any()) // <<-----
{
DetailsView1.DataSource = q;
DetailsView1.DataBind();
}
else
{
Literal1.Text = "Data not found";
}

You can also use count method .Count()
if (q.count()>0)
{
DetailsView1.DataSource = q;
DetailsView1.DataBind();
}
else
{
Literal1.Text = "Data not found";
}

Enum Ploblem alway value how?

public enum FrameStatus
{
NotReport = 0,
NormalStatus = 1,
NotNormalstatus = 2
}
but alway FrameStatus.NormalStatus how?
public FrameStatus FrameReportStatus(int Framid, string Timebet)
{
foreach (FrameCam fc in al)
{
if (fc.Timebet == Timebet && fc.IdFrame == Framid)
{
if ((int)fc.status == 1) fc.status = FrameStatus.NormalStatus;
else if ((int)fc.status == 2) fc.status = FrameStatus.NotNormalstatus;
else fc.status = FrameStatus.NotReport;
return fc.status;
}
}
return FrameStatus.NotReport;
}
my complete classs
class FrameCam
{
private ArrayList al = new ArrayList();
public string strConnect;
public FrameStatus status = FrameStatus.NormalStatus;
public string Timebet;
public int IdFrame;
public FrameCam()

public FrameCam(string st, string bt)
{

return fc.status;
}
}
return FrameStatus.NotReport;
}
}

You're not assigning anything to fc.Status within LoadToList and the initialize for FrameCam's 'status' field is "FrameStatus.NormalStatus". If you update the code in LoadToList to assign to fc.status (instead of this.status, as is shown here) then it should work as you expect.
As a side note, LoadToList should be a static method, which would have mitigated this problem.

Use a debugger. Step through the code.
The code is not taking the path you think it is taking.
If you do not know how to step through code in a debugger, you MUST learn.
This is not an optional skill for a computer programmer.
