Unable to get a table data from SAP

This is a c# method that invokes SAP BAPI.
public Message ReleaseBapi(string orderNumber)
{
Message msg = new Message();
DataTable dt = new DataTable();
_ecc = ERPRfcDestination.InitialiseDestination();
try
{
IRfcFunction api = _ecc.Repository.CreateFunction("BAPI_PRODORD_RELEASE");
IRfcTable orderNumTable = api.GetTable("ORDERS");
orderNumTable.Insert();
IRfcStructure ItemData = orderNumTable.CurrentRow;
orderNumber = orderNumber.PadLeft(12,'0');
ItemData.SetValue("ORDER_NUMBER", orderNumber);
api.SetValue("ORDERS", orderNumTable);
BeginContext();
api.Invoke(_ecc);
//EndContext();
IRfcTable detReturnTable = api.GetTable("DETAIL_RETURN");//On this line I am getting RfcInvalidStateException
IRFCToDatatable convertToDT = new IRFCToDatatable();
dt = convertToDT.ToDataTable(detReturnTable, dt);
if (dt.Rows.Count > 0)
{
msg.Msg = "Order number " + orderNumber + " released";
msg.MsgType = "S";
}
else { RollbackAPI(); }
}
catch (Exception ex)
{
msg.MsgType = "D";
msg.Msg = ex.Message;
RollbackAPI();
}
finally
{
EndContext();
}
return msg;
}
I checked every other instances where similar line of code is written and on debugging I found that it works as expected. Above is the only place where I am getting this error although I was able to invoke the Rfc method.

How to transfer payment line into Sage 50?

I'm using sagecrmErp2008feeds to the integration with my application. I'm able to create SalesCredit and SalesInvoice data. But I would like to transfer payment data from my application to Sage50.
Which feed Entry should I use for that for payment transfer ? Please see my Invoice code example. I would like to use the same way to transfer payment but I'm not getting feedentry for that. Here I'm using salesInvoiceFeedEntry feed entry.
public IResult<string> CreateSalesInvoice(Sage50Transaction data)
{
var result = new Result<string>();
try
{
var tradingAccount = GetCustomer(data.CustomerGuid);
if (tradingAccount == null)
{
throw new Exception("Customer not found in Sage");
}
var salesInvoice = new salesInvoiceFeedEntry
{
tradingAccount = tradingAccount
};
salesInvoice.reference = data.ReferenceId;
salesInvoice.reference2 = data.OurRef;
salesInvoice.customerReference = data.YourRef;
salesInvoice.netTotal = data.NetSub;
salesInvoice.taxDate = data.TransactionDate;
salesInvoice.date = data.TransactionDate;
salesInvoice.salesInvoiceLines = new salesInvoiceLineFeed();
if (data.Lines != null)
{
foreach (var item in data.Lines)
{
salesInvoice.salesInvoiceLines.Entries.Add(GetInvoiceLineItem(item));
}
}
var invoiceRequest = new SDataRequest(uri.Uri, salesInvoice, Sage.Integration.Messaging.Model.RequestVerb.POST);
invoiceRequest.Username = Username;
invoiceRequest.Password = Password;
salesInvoiceFeedEntry savedSalesInvoice = new salesInvoiceFeedEntry();
invoiceRequest.RequestFeedEntry<salesInvoiceFeedEntry>(savedSalesInvoice);
result.Data = savedSalesInvoice.UUID.ToString();
result.HasData = !string.IsNullOrEmpty(result.Data);
}
catch (Exception ex)
{
result.HasData = false;
result.Data = null;
result.Error = ex;
result.FailMessage = ex.Message;
}
return result;
}

As per my understanding, "payment transfer" is not possible from 3rd party to sage50, as the Sage 50 Accounts does not support this.

Validating digitaly signed PDF Spire.Pdf C#

So I am developing a web app that generates a PDF contract from a partial view, and then validates the digital signiture. I came accross an example here . The problem is that an exception is thrown when validating the signiture and for the life of me I cant figure out why...
Here is the code :
public async Task<ActionResult> Upload(HttpPostedFileBase FileUpload)
{
ActionResult retVal = View();
AspNetUser user = DbCtx.AspNetUsers.Find(User.Identity.GetUserId());
bool signitureIsValid = false;
string blobUrl = string.Empty;
if (FileUpload != null && FileUpload.ContentLength > 0)
{
string fileName = Guid.NewGuid().ToString() + RemoveAllSpaces(FileUpload.FileName);
string filePath = Path.Combine(System.Web.Hosting.HostingEnvironment.MapPath("~/Content/pdfs"), fileName);
FileUpload.SaveAs(filePath);
List<PdfSignature> signatures = new List<PdfSignature>();
using (var doc = new PdfDocument(filePath))
{
var form = (PdfFormWidget) doc.Form;
int count = 0;
try
{
count = form.FieldsWidget.Count;
}
catch
{
count = 0;
}
for (int i = 0; i < count; ++i)
{
var field = form.FieldsWidget[i] as PdfSignatureFieldWidget;
if (field != null && field.Signature != null)
{
PdfSignature signature = field.Signature;
signatures.Add(signature);
}
}
}
PdfSignature signatureOne = signatures[0];
try
{
signitureIsValid = signatureOne.VerifySignature(); // HERE SHE BLOWS !
if (signitureIsValid)
{
blobPactUrl = await BlobUtil.BasicStorageBlockBlobOperationsAsync(System.IO.File.ReadAllBytes(filePath));
if (!string.IsNullOrEmpty(blobPactUrl))
{
ApplicantInfo info = DbCtx.ApplicantInfoes.FirstOrDefault(x => x.UserId == user.Id);
info.URL = blobUrl;
info.SignatureIsValid = true;
info.ActivationDate = DateTime.Now;
info.ActiveUntill = DateTime.Now.AddYears(1);
DbCtx.Entry(info).State = System.Data.Entity.EntityState.Modified;
DbCtx.SaveChanges();
retVal = RedirectToAction("Publications");
}
}
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
finally
{
System.IO.File.Delete(filePath);
}
}
return retVal;
}
Here is an image of
what it looks like when I'm debuging:
I have checked the signiture and it is valid and cerified... I know I'm missing something basic here... Please help me internet!

Just noticed that I posted this. . . Turns out that the problem was due to bug in the package itself. Upon asking the lovely people at E-Iceblue, the bug was recreated, solved and a new version of Spire.PDF was up on nuget within a week.
great job E-Iceblue, it worked fine :)

Connect to a Webservice - convert C# to PHP code

I have a sample code I got from a documentation provided by a merchant. I think the code is in C#. I need to write a code for PHP but I don't have any idea about C# so I'm having a problem with this. I've tried to write a PHP code for this but it doesn't seem right.
By the way, this is a webservice kind of setup and it uses WCF to expose various endpoints. Here's the endpoint they've provided to me: http://services.scorpion.biz/Public/Leads/ExternalLead.svc
Here's the C# code:
public bool SubmitLead(string contactName, string contactNumber) {
bool outcome = false;
string message = string.Empty;
if (contactNumber.Length <= 9) {
message = "Telephone number is too short";
outcome = false;
} else if (contactNumber.Length > 11) {
message = "Telephone number is too long";
outcome = false;
} else if (contactNumber.Length == 10 && contactNumber[0] != '0') {
message = "Telephone must start with a ZERO";
outcome = false;
} else if (contactNumber.Length == 11 && contactNumber.Substring(0, 2) != "27") {
message = "Telephone must start with a 27";
outcome = false;
} else {
WSExternalLead.LeadRequestMessage request = new
WSExternalLead.LeadRequestMessage();
request.Message = “Your Keyword” + ". Contact Name: " + contactName + ".
Contact Number: " + contactNumber;
request.TelephoneNumber = contactNumber;
request.Network = “IMU”;
request.ReceivedTime = DateTime.Now;
using (WSExternalLead.ExternalLeadClient client = new WSExternalLead.ExternalLeadClient()) {
try {
WSExternalLead.LeadResponseMessage response = null;
response = client.GenerateLead(request);
if (response.Result != true) {
message = "We were unable to process your request at this
time. Error: " + response.ErrorMessage;
outcome = false;
} else {
message = "Thank you for your interest in Scorpion Legal
Protection. We will get back to you shortly.";
outcome = true;
}
} catch (FaultException fx) {
message = "We were unable to process your request at this time.
Fault: " + fx.Message;
outcome = false;
} catch (Exception ex) {
message = "We were unable to process your request at this time.
Exception: " + ex.Message;
outcome = false;
}
}
}
HttpContext.Current.Session["OUTCOME"] = outcome;
HttpContext.Current.Session["MESSAGE"] = message;
return outcome;
}
Here's the PHP code that I've written:
// Read values to variables
$username = $_GET['un'];
$usersurname = $_GET['ul'];
$phonesubmit= $_GET['up'];
$useremail = $_GET['ue'];
$aff_id = $_GET['aff'];
$unique_id = $_GET['uid'];
$rdate = date('m/d/Y G:i:s');
$rdate = date("c", strtotime($rdate));
$wsdlFile = "http://services.scorpion.biz/Public/Leads/ExternalLead.svc?WSDL";
$client = new SoapClient($wsdlFile);
$variables->TelephoneNumber = $phonesubmit;
$variables->Message = "IMU. Name: $username $usersurname. Contact Number: $phonesubmit";
$variables->Network = "IMU";
$variables->ReceivedTime = $rdate;
$result = $client->GenerateLead($variables);
$returnMessage = $result->Result;
$returnMessage = trim($returnMessage);
if ($returnMessage == ""){
$returnMessage = $result->ErrorMessage;
}
Any idea on how to solve this would be greatly appreciated. Thanks.

SQLite connection strategies

I have a database that may be on the network drive.
There are two things that I want to achieve:
When the first user connects to it in read-only mode (he doesn't
have a read-write access to the location, or the database is
read-only), other users must use the read-only connection also (even
if they have RW access).
When the first user connects to it in RW mode, others can not
connect to the database at all.
I'm using SQLite, and the concurrency should not be the problem, as the database should never be used by more than 10 people at the same time.
UPDATE: This is a sample that I'm trying to make work, so I could implement it in the program itself. Almost everything can be changed.
UPDATE: Now when I finally understood what #CL. was telling me, I made it work and this is the updated code.

Set PRAGMA locking_mode=EXCLUSIVE to prevent SQLite from releasing its locks after a transaction ends.

I don't know if it can be done within db but in application;
You can set a global variable (not sure if it's a web or desktop app) to check if anyone connected and he has a write access or not.
After that you can check the other client's state.
