I've used FirebirdClient 2.0 ADO.NET and I'm migrating to FirebirdClint version 5.7 ADO.NET.
This code below does not work in the new version of firebirdClient
If IO.File.Exists(pathScript) Then
txtScript.Close()
Dim fbScript As New FbScript(pathScript)
fbScript.Parse()
If fbScript.Results.Count = 0 Then
Exit Sub
End If
If fbScript.Results.Count > 0 Then
If automatico = False Then
frmImpSintegra.LblTitulo.Text = "Gravando 60I"
End If
Application.DoEvents()
Dim fbConn As New FbConnection(cnEmpresa)
fbConn.Open()
Dim fbBatch As New FirebirdSql.Data.Isql.FbBatchExecution(fbConn)
fbBatch.AppendSqlStatements(fbScript)
fbBatch.Execute(True)
fbConn.Close()
End If
deleteArquivoTemporario()
txtScript = New IO.StreamWriter(pathScript)
End If
This error appears in the line fbScript.Parse ()

Can someone help me?
You are passing the filename to the constructor of FbScript, but this constructor is expecting the actual script content. This leads to the filename c:\0556_16122016_081323.txt to be parsed as if it is a statement, and c:\0556_16122016_081323.txt is not a known Firebird statement.
Instead you should use FbScript.LoadFromFile(pathScript).

I have a SQL Server stored procedure that is used for uploading a document and returns an ID upon success.
I am storing the parameter file_data into a byte[] type in the Customer_Document_ADD class.
public byte[] file_data { get; set; }
The following is my repository code.
public async Task<int> InsertCustomer_Document_ADDResult(Customer_Document_ADD customer_Document_ADDED)
{
await using(SqlConnection connection = new SqlConnection(_connectionString))
{
connection.Open();
// define SqlParameters for the other two params to be passed
var company_idParam = new SqlParameter("#company_id", customer_Document_ADDED.company_id);
var customer_idParam = new SqlParameter("#customer_id", customer_Document_ADDED.customer_id);

All other values are captured except the file. I am getting a null value in the debugger. Why am I unable to upload a file into the database? Thanks in advance.
Firstly,default model binding system cannot bind file to byte[] properties.If you want to bind file to btye[],you can use ByteArrayModelBinder,here is an official link.
Also,if you don't mind to change the type of file_data,you can use
public IFormFile file_data { get; set; }
and then you can convert it to byte[] type with MemoryStream.Here is an official link about upload files in .net core.
I'm creating a web application for the parish in angular.
It is a CRUD web application in which I use SQL Server.
I have the product-list.component page where I created the OnDelete method to be able to delete the single product.
The method is correct, but I have a problem that in the table there are relations to the "CommandRighe" table that inhibit deletion.
I modified the OnDelete method with try catch to be able to intercept the error code and send an error message to the user.
It does not work and I would like to know how to handle the problem in order to send the user an error message telling him that the record cannot be deleted.
How can I do ?
thank you

I have created a dynamic function to my class using MSIL emit statements and I have hosted the class as WCF service.
Emitted code :
Type myMthdParams = new Type[2] {};
myMthdParams[0] = typeof(int);
myMthdParams[1] = typeof(int);
MethodBuilder myMthdBld = myTypeBld.DefineMethod("Add", MethodAttributes.Public | MethodAttributes.Static, typeof(int), myMthdParams);
ILGenerator ILout = myMthdBld.GetILGenerator();
int numParams = mthdParams.Length;
for (byte x = 0; x < numParams; x++)
ILout.Emit(OpCodes.Ldarg_S, x);
if (numParams > 1)
{
for (int y = 0; y < (numParams - 1); y++)
{
ILout.Emit(OpCodes.Add);
}
}
ILout.Emit(OpCodes.Ret);
The method is "int add (int, int)".
This is how the proxy looks from client
public int Add(int in0, int in1) {
ConsoleApplication4.ServiceReference2.AddRequest inValue = new ConsoleApplication4.ServiceReference2.AddRequest();
inValue.in0 = in0;
inValue.in1 = in1;
ConsoleApplication4.ServiceReference2.AddResponse retVal = ((ConsoleApplication4.ServiceReference2.MyDynamicType)(this)).Add(inValue);
return retVal.AddResult;
}
Client call :
var v = client.Add(int, int);
However when I try calling this function from a client side I get the following exception - "An unhandled exception of type 'System.ServiceModel.FaultException`1' occurred in mscorlib.dll"
Additional information: Index was outside the bounds of the array.

Any help is deeply appreciated. Thanks.
First, I would like to tell that i am new on the .net development (MVC 4)
and I am trying to follow this tutorial with entity framework 5 but I keep getting this error " exception of type 'System.NullReferenceException' occurred in jqGridMVC2.dll but was not handled in user code
Additional information: Object reference not set to an instance of an object.
, even though i tried to cheeck the value for null before.
if(propInfo.GetValue(this, null) != null) {
}
private static object GetPropertyValue(object obj, string property)
{
System.Reflection.PropertyInfo propertyInfo = obj.GetType().GetProperty(property);
// if (obj != null)
// if (propertyInfo.GetValue(obj, null) != null)
return propertyInfo.GetValue(obj, null);
// return 0;

Please help me in solving this problem
Thank you in advance.
I just solve the error by this
private static object GetPropertyValue(object obj, string property)
{
foreach (var property1 in obj.GetType().GetProperties()) {
return property1.GetValue(obj, null); //throws exception TargetParameterCountException for String type
}
return 0;
}
I am trying to fetch all Product where the CheckedOutToGuid is null or is the Guid of the current user. I have tried to use the following QueryOver:
public IEnumerable<IProduct> GetProducts(IUser user, Expression<Func<IProduct, bool>> predicate)
{
return Context.GetSession().QueryOver<Product>()
.Where(x => (x.CheckedOutByGuid == null) || Guid.Equals(user.UserGuid, x.CheckedOutByGuid)
.OrderBy(x => x.Version).Desc
.OrderBy(x => x.DisplayName).Asc.List();
}
but I get an error:
Atf.NUnit.Model.TestDatabase.TestModule1():
System.Exception : Unrecognised method call: System.Object:Boolean Equals(System.Object, System.Object)
What is the cause of this error? I tried removing (x.CheckedOutByGuid == null) so that no OR is necessary but still get the same error.
UPDATE
As #Andrew Whitakersugggested, I changed one line
.Where(x => (x.CheckedOutByGuid == null) || (user.UserGuid == x.CheckedOutByGuid))
This now causes the following exception:
Atf.NUnit.Model.TestDatabase.TestModule1():

Well, I then tried this:
public IEnumerable<IProduct> GetProducts(IUser user, Expression<Func<IProduct, bool>> predicate)
{
Guid g = user.UserGuid;
return Context.GetSession().QueryOver<Product>()
.Where(x => (x.CheckedOutByGuid == null) || (g == x.CheckedOutByGuid))
.OrderBy(x => x.Version).Desc
.OrderBy(x => x.DisplayName_DE).Asc.List();
}
and this is when I found that user is null :-( This was the cause of the error. The error messages led me in quite the wrong direction.
NHibernate is attempting to turn Guid.Equals into a SQL expression. NHibernate doesn't recognize Guid.Equals as something it can turn into SQL, hence the exception.
If you change that line to read:
.Where(x => (x.CheckedOutByGuid == null) || user.UserGuid == x.CheckedOutByGuid)
Everything should work fine.
