Create DB With More 65535 Records?
May 24, 2011
Usually when I need to create a DB with excel files(in order to get records that I need), I used following
HTML
Excelconnection = New OleDbConnection("provider=Microsoft.Jet.OLEDB.4.0; data source=" + mypath + "; Extended Properties='Excel 8.0;HDR=Yes;IMEX=1'")
Excelconnection.Open()[code]....
where mypath contains path of excel files.Now I have a file with no extension where structure is: each record is separated by space and row are more than 65535.I saw that with csv file I can solve this issue but I don't know if OLEDB connection to csv file works fine.I don't want to create several sheets.

I have a datagrid which contains 750 columns. When I try to assign it to datasource, I get the following error
An unhandled exception of type 'System.InvalidOperationException' occurred in System.Windows.Forms.dll
Additional information: Sum of the columns' FillWeight values cannot exceed 65535.
My code is as follows
Public TaView As DataView
Dim table As DataTable = New DataTable
[Code]....
I think I need to SetWeight to 1 for all columns. But how can it be done before assigning to datasource.

My application is in VB.Net and I'm using the driver of IBM Client Access to access data on our IBM iSeries server.
The problem is that some characters are not translated automatically in CCSID 65535 (i.e. the € character) and the update/insert command fails.
I don't know on which level the problem must be handled. On the ODBC driver ? In the connection string ? Or do we have to create a conversion dll ?

I am essentially trying to create a list of records in VB.net using the 1.1 framework.It seems that I should be using an object even though I have only properties but no methods (more like a traditional record), I would like to store a list of objects, how can I create the list and add an instance of the object to the list.I do have sample code that almost works but it is too poor for public display.

I am trying to create an application that records screenshots every 50 milliseconds... And It works below:
Private Sub Timer1_Tick(sender As System.Object, e As System.EventArgs) Handles Timer1.Tick
Dim b As Bitmap = New Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height)

But after 30 seconds I see an ArgumentException on the second line...
Does anyone have a solution or an alternate method of capturing the screen like this?

Create a class to deal with records from the Classes table, much like the Student class we created in Lecture #17 handles Students records. The name of the class should be Ualb_Class (note we cannot use Class, as it is a reserved word in VBA). All of the fields should have corresponding properties. There are few considerations:
The class (course) code, department code, and course number are set at Initialize, so there is only a Get property method for those
The property for Meeting Day only accepts one of the values defined in the table. You can decide whether to accept an integer value or a string value of the days represented.
You are also to code the Initialize method, much like we coded the Initialize method for the Student class in Lecture #17. In the Initialize method, you will use the InputBox function to obtain the department code and course number. use a different InputBox for each value, so you don't have to mess with separating the single text value returned from that function. The Course Code will be obtained by using a function that has already been created, called GetNewCourseID. It has no parameters.
TABLE: Classes

I'm using Visual Basic 2005 and I have created a program to display, edit, and create insurance records. Right now I am using an access database and it is hosted locally. What I want to be able to do is host it on our server here at our office and have the program installed on every computer on the network.
My connection string at the moment looks like this:
Code:
Public con As New OleDb.OleDbConnection
con.ConnectionString = "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source = C:Insurance ProgramInsurances.mdb"
'Opens connection

I have been playing with VB6 for quite a few years now and I can normally get by ok on my own.I finally made the move to VB.net, but I am totally lost.I have started writing a program that is basically a planner. It helps the user organize and plan activities with a client.I have created the ui and have added a BindingNavigator and it happily pulls in the records from my Access database which I can cycle through.What I would like it to be able to do is, allow the user to see all the current records (maybe in a flexgrid), select which record he/she would like to view, then the entire record is populated into the ui.I would have no problem in vb6 of course...but I could do with a little help in vb.net (2008).My main problem is I think is, once the flexgrid is populated, how to create the event that allows the user to view and update that record once in the ui.

I have an MSAccess 2007 DB to record our employees Personal Days Off (PDO). Until now I have only had a form to record each single day taken. This results in time consuming repetitive entry when an employee takes multiple consecutive days or weeks off.
My database consists of two tables:tbl_PDO (to hold the Worker, DateTakenOff and TimeTaken) tbl_Employees (containing the Employees contact info, Name, Address, etc.) A form for Single date data entry with tbl_PDO as the record source and the following fields: (This is the original entry method one day at a time and works as it should)cboWorker(with Record Source tbl_Employee[Worker] DateTakenOff(ShortDate) TimeTaken (in hours) A form for Date Range entry with tbl_PDO as the recored source and the following fields: cboWorker(with Record Source tbl_Employee[Worker] StartDate EndDate TimeTaken (in hours) I have been trying to work with bits and pieces of code Ive found online to create multiple rows in a table based on a date range.[code]...

i have a simple application which can create/update/delete/search records using Access database. If i add a record, save it, then close the application and run it again and search for that record, it appears. However, when i write some code to my application, nothing to do with the search function, and i run the application the record is not found. For example i added a button to clear the textfields, and when i ran the application the records i have added earlier were not found.
