Hi I trying to get the max timedate from a table using LinqToSQL. I already asked a similar question, but was trying to do something a bit more specific, and no one was able to help. This time, i would not mind using any solution, short of an Execute SQL task in another part of the SSIS package. This is my whole code. I was trying just to get the Identity column and it wasnt even working, so ignore the ToString please if it seems out of place. I just want to get the latest CREATED_TIMESTAMP please

i am using a method to retrieve data from an OPC DA server using TitaniumAS packages, the problem i am having is that i have a lot of tags to read/write so i have to use methods.
The WriteX method works fines as it doesnt have to return anything but the read does not, well it does its job, it reads but i cannot use that data outside of the method because it was a void method, when i tried to use it as a String method (that's the type of data i need) it says :
Error CS0161 'ReadX(string, string)': not all code paths return a value
PS : note that i am just a beginner in C#
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using TitaniumAS.Opc.Client.Common;
using TitaniumAS.Opc.Client.Da;
using TitaniumAS.Opc.Client.Da.Browsing;

using System.Threading.Channels;
using Async;
namespace OPCDA
{
class Program
{
static void Main(string[] args)
{
TitaniumAS.Opc.Client.Bootstrap.Initialize();
Uri url = UrlBuilder.Build("Kepware.KEPServerEX.V6");
using (var server = new OpcDaServer(url))
{
server.Connect();
OpcDaGroup group = server.AddGroup("MyGroup");
group.IsActive = true;
Ascon ascon1 = new Ascon();
ReadX("Channel1.Ascon1.AsconS", ascon1.ALM);
Console.WriteLine("value = {0}", ascon1.ALM);
void WriteX(String Link, String Ascon)
{
var definition1 = new OpcDaItemDefinition
{
ItemId = Link,
IsActive = true
};
OpcDaItemDefinition[] definitions = { definition1 };
OpcDaItemResult[] results = group.AddItems(definitions);
OpcDaItem tag = group.Items.FirstOrDefault(i => i.ItemId == Link);
OpcDaItem[] items = { tag };
object[] Values = { Ascon };
HRESULT[] Results = group.Write(items, Values);
}
string ReadX(String Link, String read)
{
var definition1 = new OpcDaItemDefinition
{
ItemId = Link,
IsActive = true
};
OpcDaItemDefinition[] definitions = { definition1 };
OpcDaItemResult[] results = group.AddItems(definitions);
OpcDaItemValue[] values = group.Read(group.Items, OpcDaDataSource.Device);
read = Convert.ToString(values[0].Value);
}
}
}
}
}
the first step was to state the return like this :
return Convert.ToString(values[0].Value) instead of read = Convert.ToString(values[0].Value)
then go up and use that value with my variable :
ascon1.ALM=ReadX("Channel1.Ascon1.AsconS");
This code filters elements of certain category and finds and concatenates parameters although what needed is something a little more complex.
First of all, a person needs to be able to choose a category (out of a drop down list) or search and find the necessary ones.
And the second thing is that a user is supposed to specify what parameters he would like to combine (we have shared parameters txt fyi) and choose the order in which they are going to follow one another. Any resource on it or something similar to it would help greatly!

In your Code you commented out "System.Diagnostics.Process.Start(#"C:\Program
Files\SAP\FrontEnd\SAPgui\saplogon.exe");"
Go with this aproach, but use "sapshcut.exe" from the same Folder instead!
(this will be available on the most systems)
In this case it could be as simple as that:
string strProg="C:\Program Files\SAP\FrontEnd\SAPgui\sapshcut.exe";
string strParam="-system=N7P -client=460 -user=youruser -password=yourpassword -language=EN";
System.Diagnostics.Process.Start(strProg,strParam);
Find an (VBA)Examle with some pre-Tests on the Commanline at trouble using excel macro for access to sap
Hope this will do ist for you!
Hi please can anyone give me solution to this problem,i have to import csv file using c# but i have this problem in this screenshot
Screen
the separate betwenn column is ',' but in the data there is a rows tha contains ".
Mohamed, I cannot see your screenshot, but can point you toward generic lists and creating a class to represent data. You will need to add references from the "Project" menu.

}
}
}
Google TestFieldParser and look at the methods, properties and constructors. It is very versatile, but runs slowly due to the layers it goes through. It has the ability to set the delimiter, handle fields wrapped in quotes, trim whitespace and many more.
My purpose on this is to insert a autonumber for this format AN-00000000 to the db, with the type in db varchar.
my code in windows form is saving a integer number already "10000000".
But I turn on my mind and think if possible that the auto number will be like this AN-00000000 and to save to the db with a character string.
I tried my best to change and apply but suddenly I can not implement because is on the integer part.
I am creating the basic system in our company to create a automate membership for the members, in our company we have 4 parts of membership which is Dep, sep, mep and cef, so I turn on my mind that i need to implement the 4 Id with the following to identify what the department they included. like DEP-00000001, SEP-00000001, MEP-0000001 and CEF-00000001.
Can anyone suggest or give their opinion on my code below? Thanks!

You are probably throwing a FormatException on the above line now if the string contains more than 0-9.
FormatException - value does not consist of an optional sign followed by
a sequence of digits (0 through 9).
If you know the first 4 chars will always be "XXX-" (e.g. "MEP-") then why don't you:
int pcount1 = Convert.ToInt32(pcount.Substring(4)); // ######## part
int pcountAdd = pcount1 + 1; // ######## + 1
textBox1.Text = String.Format("{0}-{1:D8}", pcount.Substring(0, 4), pcountAdd);
Which will convert only the numeric part, increment it, and then concatenate it with the first part.
Also you can look into the TryParse method. Which will indicate if your parse succeeded.
TryParse - Converts the string representation of a number to its 32-bit signed
integer equivalent. A return value indicates whether the operation succeeded.
