Here is the part of the code that will error out. Specifically the
da.Update(ds, "info") Everything works fine with the datasets on the form and I can manipulate everything just fine. When it comes down to actually updating the changes to my database it errors out. Here is the entire code.
Imports System.Data
Public Class Form1
Dim inc As Integer
Dim maxrows As Integer

Creating a new database in a Windows Forms project (done according to one of the MSDN tutorials) results immediately in a "The event log is full" error.The database exists as an item in the project, but cannot be opened or configured (i.e.,it doesn't exist really). newly installed MS SQL Server Compact Edition,This is a new computer (though fully updated), and to my knowledge no other versions of SQL server are installed.I note that someone else has contributed a message about the exact same problem (according to a preview in the MSDN search results page), although for unknown reasons clicking on the item does not take me to that message.

My plan is to send emails from the application interface and insert the data into the database; I understand how to do this completely.What I am struggling with is how to receive the emails, parse them and then insert that data into the database.

I'm trying to accept two pieces of data from two textboxes, which will then be inserted into a database on pressing enter, along with a date stamp, and a time stamp. My two text boxes are called; txtindicatorand txtemployee, the database is called; Database11 (Database11DataSet1).
The data would be imported into a table named; Data_Collection and the fields would be; Employee ID (which would come from the info the user inserted into 'txtemployee'), Time (automatic time stamp), Date (automatic date stamp), Type (which would be identified from textbox 'txtindicator').

I am taking my first quarter of programming and am having a VERY difficult time understanding jagged arrays. At the moment I am working on a project that is using two two dimensional jagged arrays
If IsNothing(g_decChargesArray(g_intActivePatientNumb er)) Then
numVisits = 0
Dim decTemp(g_intActivePatientNumber) As Decimal[code].....
The line in bold is the only way I can think of to pass the amount of decCharges into the array g_decChargesArray.

This is a bit of unusual problem that I'm experiencing, but recently one of the users of a production application started reporting errors in the system. These were traced to a 503 Service Unavailable error when making a call to a web service used by the application.
Now here's the odd part, only the one user is affected by this issue. Other users of the application have not reported any errors. When the user logged on to a different machine that worked for another user, they still received the error.

I am creating a simple email application which sends mail from a user's Gmail account, as I haven't worked out how to receive incoming mail yet.I have created a form (frmSignIn) which asks for the log-in info and another (frmComposeMessage) which has all text boxes necessary for composing an email (to, subject, message body).After clicking Sign In on the first form, it should hide it and open the second form, however I get this error:
System.InvalidOperationException was unhandled
Message=An error occurred creating the form. See Exception.InnerException for details. The error is: Object reference not set to an instance of an object.

I'm developing vb.net application with mysql as database. The database is on other machine in the network. In one function connection opens and executes query successfully. The same function makes call to other function.This second function tries ot do same thing. But this time while opening connection it gives error-"Access denied for user 'root1'@'AZAR' (using password: NO)". Here 'AZAR' is the name of my machine. The first function uses public variable declared in module for connection, whereas second function uses local variable for connection. I'm using PhpMyAdmin tool.

Dim excel As New Microsoft.Office.Interop.Excel.Application()
Dim wb As Microsoft.Office.Interop.Excel.Workbook = excel.Workbooks.Open(txtFileLocations.Lines(w))
Dim ws As Microsoft.Office.Interop.Excel.Worksheet = TryCast(excel.ActiveSheet, Microsoft.Office.Interop.Excel.Worksheet)
when the program tries to opens an excel file, it always throws me an error "Office has detected a problem with this file. Editing may hard your computer" and my program crushes.......The problem appears on the SECOND line, on DIM wb...blahblah.. i went to the office and unclicked the "protected view" checkboxes.. but it still throws me those errors. my guess is that the office i have in the computer is not the same as the one that my program uses to open excel files (i mean, i loaded/imported some excel.dll files in the program so i guess that will be the one) But how do i make the program not care if the excel file is "potentially dangerous"?
