Access SAP R/3 Data Directly From .NET?
Sep 21, 2010We have an assignment to create some XML outputs from data in SAP R/3. We are using SAP .NET Connector, for doing this. The problem we are facing is that there are some fields which are not exposed by any standard BAPI. Unfortunately we cannot create customized BAPI on this particular system.
We are therefore restricted to whatever standard BAPI are available. I have seen on internet that tools like ERPConnect can provide access to tables directly using RFC. How can this be performed in VB, without purchasing any such tool, using or without using .NET Connector.

View 2 RepliesRead From CSV File, Write Directly To Data Source
Sep 7, 2011I'm trying to "convert" an Access DB to a stand alone application. I have under estimated the differences between VBA and VB. Although I have many questions, I'll focus on this topic first.
The Access DB collects and maintains SNMP traps from a radio station. I import CSV files from a remote Unix server via FTP, parse the text line-by-line, and add to a table as a new record. So far, I can parse the text and add to a dataset but I want to write directly to the data source. I also need error handling that will trap errors for duplicate records. There is a Reconcile function that ensures that all lines in the CSV files are added to the table before the files are permanently deleted. Here's what I have so far:
Public Class clsRnm
Private msTrapTable As String
Private moTrap As clsRnmTrap

View 2 RepliesDefine A 3 Dimensions Matrix With Different Data Types?
Dec 8, 2011I define 3 arrays: ID(n), Hour(n), Showed(n). If Hour(i) = actual time, I get the data pointed by ID(i), if not Showed(i).
BUT... I can add new hours or modify some existent, but I need to have the Hour array sorted. If I sort this array, the ID and Showed will point to different data.
So I though some different solutions:
1 - To make a string array with all inside (a 7 characters ID, a 5 characters Hour and 1 char for showed (T or F)). It could work, but, how can I sort the middle part of the array (Hour)? So, this don't work.
2 - A 3 dimensions "multitype" matrix (1 dimension of type Integer, the second of type Date and the third of type Boolean). I have no idea about how this can be done.
3 - A 3 dimensions string matrix, some like the "all inside" array: ID converted to a fixed size string, hour converted to a 5 chars string (hh:mm) and Showed converted to T or F. And sort the second dimension.

Saving Directly From A Datagrid To A Table In A Database?
Apr 7, 2011Basically I have a DataGrid on a form that is used to monitor attendance. I do this by making the data types for the relevant fields boolean so that at runtime, they appear as check boxes that the user can tick. If the user ticks this then the table in MySQL saves this as a 1, or if it is left unticked the table saves it as a 0. I then use those values in a mathematical equation to calculate weekly attendance.
My problem, however, is with saving changes to the table itself. Initially I set a primary key which was fine and allowed me to save. However I needed to turn that primary key to a foreign key and when I do that, I am told that I need a primary key. Now I got round that before when I was entering data into a text box and in my SQL query I'd simply put as my value being " & (name of textbox).Text & " but when I am entering data straight onto the datagrid, I am unsure of what to put in my SQL statement.
StudentID (Was primary key but turned it into foreign key)
Name
Surname
Monday
[cod]....
My friend from college told me it's probably because there are multiple records in the database and can't distinguish between the two (as perhaps there's no WHERE clause in that UpdateCommand) but I doubt it as it was working perfectly well with multiple records when StudentID was a primary key.
Access SQL Table Data From VB
Sep 18, 2009how can I access SQL data from VB? I am working on a purchased application with a bunch of 3rd party VB controls. What I would like to accomplish is to validate certain controls for user entry and I have one 3rd party control that has a table grid in it displaying SQL data and was wondering if it's possible to validate that SQL table data. And to complicate things, the 3rd party control is located in a different form altogether from the form where I need to insert my validation button.

View 1 RepliesHow To Access Table Data Via DataSet
Feb 17, 2012I'm confused about DataSources and DataSets.I created a DataSource (DataSet?) via the DataSource wizard called PPIDataSet. This has tables in it Customer, Vendor, Orders, etc.Now I want to access the data in these tables via code. So I'm expecting to be able to do PPIDataSet.Customer.AddRow or something like that. However, when I access the PPIDataSet object, in IntelliSense,I only get PPIDataSet.CustomerDataTable PPIDataSet.CustomerRow
How do I access the table data via the DataSet? Or do I have to access it some other way?

Adding A Column To An Access Data Table Through VB?
Nov 22, 2011I have already binded a data source from Access to my visual basic program but need to add a True/False column to two of the tables. I could do this manually in access and re-bind the sources but that would take up too much of my time so I wanted to know if I'm using the proper code to add a column to the data table directly from VB? Here is the code I want to try but I don't know where to place it?
OleDbCommand = OleDbCommand("ALTER TABLE tableName ADD
FieldName DataType");
(something).Connection = OleDbConnection;
[Code]....
I'm not sure what goes into the "something" parenthesis and where this code must go. I already tried editting through the data designer but although it shows the column in the DataGridView, it does not save any data or the column into the actual access file.
