I have a dataset with numerous tables.I have changed the column type of a couple of columns in the source DB form smallint to int.No I need to update the datasets (and eventually the code) to the appropriate datatype.Rather than hunt around the dataset and find all the places where these columns are referenced is there a way to direct the dataset to go back to the DB, reread the queries and update the datatypes.I know I can either change the field or one by one go to each table and force it reread the query but I want the dataset to do it in mass.

I am new to this forum. I have created a module in which declared one structured in public. There were some fields earlier in the structure.
[Code]...
I have included statement includes project.modulename in my main project form where i am referring this structure. everything worked fine. Today, i added new field to the structure by name "example as string" and written some code in module itself to access this field. even this is working fine. but when i am trying to access this field in the main code it is not showing example as structure field and saying not a member.
The drop down suggestion of IDE is not showing this field in main code but in module code it is showing the field. Later, i also found that my debugger is also not working. I tried to clean solution, restart IDE, computer but nothing seems to be working.

View 4 RepliesI have two tables namely BankAccount and MoneyTransfer to be used in a single form. Here lies my form: Attachment 72574
In the BankAccount table I have got the AccountNo,BankName and CurrentBalance columns.I am fetching the data of these columns during the form load event and filling up the combobox's of the From and To part as shown in the form snapshot. So I did this below code in the form load event:
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
con = New OleDbConnection("Provider=Microsoft.Jet.Oledb.4.0;Data Source=C:UsersGautamDocumentsVisual Studio 2005ProjectsEtech_TransferEtech_TransferBankAccount.mdb")
con.Open()
[Code] .....
Now I have a Date and Amount field in the form and I have both the columns present in the TransferMoney table. The user will first select the BankName and AccountNo. from their dropdown list,then enter an amount in the Amount field and ontransfer button click the money will be transfered from the FROM part to the TO part and the BankAccount table will get updated by the current balance of both the FROM and TO part and the Transfer money table containing the Amount and Date column will also get updated by the Amount transferred and the date in which the money is transferred.
I am working on an application which involves serial port communication with stepper motors. Now I am sending queries to the PLC via modbus protocol. There is one query in which I ask the PLC for the current position of the moving motor and display it in a current position textbox using a DO Loop. Here the problem is the textbox only displays the position at the end of the motor movement and not while the motor in movies though I have included the code to do so inside the DO loop.

I'm using sqlbulkcopy to load data into a sql2008 database, and we're getting timeout errors loading larger tables. Some tables which were loading OK are failing since indexes have been added to them. The source data is a Informix datareader. I've tried setting large values in both the connection timeout and the sqlbulkcopy.bulkcopytimeout, but the timeout usually occurs within 60 seconds, well below the timeout values I've set (240 secs). I've tried setting the .bulcopytimeout property to zero but it makes no difference. Very occasionally a load will take place - the last large table to load took 7 minutes. I've reduced the batch size to 500.
The documentation on bulkcopytimeout that I have found does not describe what the property actually means - is it the maximum time to complete the entire copy or to complete one batch or what ?Here's some extracts from my error log - the first shows a successful large table load, follow by timeout failures.

Part of the download was a 'key' that lets me know which file belongs to which person (I have this in excel).

Is there a way to transfer huge amount of data in a single shot from vb.net to Oracle database? I have a couple of thousands of records in my vb.net code which I want to update to Oracle database. What I do currently is, call a stored procedure in database once for each of those records. This would end up calling the stored proc couple of thousand times, which is highly inefficient.
View 2 RepliesBulk Insert is only breaking every other row. I've tried every ROWTERMINATOR I can think of, but none of them will break all lines. I've even tried to break it on exact text, and it won't break it on that exact text. I've attached a pic and circled what appears to be the line break that it refuses to recognize as a line break. When I open it up in notepad, it recognizes it as a line break.
View 7 RepliesI have an app that needs to bulk rortate a folder of images either left or right using

Recently there was a request about sending bulk email which was building a potentially dangerous collection of answers which could lead to someone easily creating a spam engine. While there are legitimate reasons to send bulk email, one must be sure to follow all the applicable rules. This means following RFC 2821 and forming properly crafted email messages. In the US, it also means complying with fedral law regarding the sending of unsolicited email (express permission must be captured through direct user initiation e.g. user's must choose to check the box to receive your email), and that means including a removal instruction as well as valid contact information.
To that end, here is an example program for sending a mass email to a list of recipient addresses located in a database. The code only cares about recieving an array of DataRow objects, so any database for which you can fill a DataTable will work.To run this example, simply place a Button on a Form and paste in the following code:
Option Strict On
''' <summary>
''' Example of safely sending bulk emails
