*)
-> unit

Parameters

cmdReadFinished: Type: LinkarClientOperationAsyncCallbackLkData
Return type in asynchronous methods.
filename: Type: SystemString
File name to read.
recordIds: Type: SystemString
It's the records codes list to read, separated by the Record Separator character (30).
dictClause (Optional): Type: SystemString
List of dictionaries to read, separated by space. If dictionaries are not indicated the function will read the complete buffer.
readOptions (Optional): Type: LinkarCommonReadOptions
Object that defines the different reading options of the Function: Calculated, dictClause, conversion, formatSpec, originalRecords.
customVars (Optional): Type: SystemString
It's a free text that will travel until the database to make the admin being able to manage additional behaviours in the standard routine SUB.LK.MAIN.CONTROL.CUSTOM. This routine will be called if the argument has content.
receiveTimeout (Optional): Type: SystemInt32
It's the maximum time in seconds that the client will keep waiting the answer by the server. By default -1 (wait indefinitely).

Copy

LinkarClt lkClt = new LinkarClt();

string filename = "LK.CUSTOMERS";
string recordId = "1";
string dictClause = "";
ReadOptions readOptions = new ReadOptions();
lkClt.ReadAsync(new LinkarClt.OperationAsyncCallbackLkData(ReadAsyncFinished), filename, recordId, dictClause, readOptions);

Dim lkClt As LinkarClt = New LinkarClt
Dim crdOpt As CredentialsOptions = New CredentialsOptions("127.0.0.1", 11300, "admin", "admin", "ENTRYPOINT")

Dim recordId As String = "1"
Dim dictClause As String = ""
Dim readOptions As ReadOptions = New ReadOptions
