Fatal Error Encountered During Data Read?
Jun 21, 2012
I am doing a regular update table scan
Using connect1 As New MySqlConnection(ConnectLocalhost.serverString)
connect1.Open()
Dim cmd = New MySqlCommand("set net_write_timeout=99999; set net_read_timeout=99999", connect1) ' // Setting tiimeout on mysqlServer
[Code].....
All I want is for the program to just "continue" when this thing happen. But that seems to be impossible. So I guess I need a way to make sure this bug doesn't happen. It happens randomly eery 800 entries or so.
Looks to me the connection is forcibly closed by remote host. In that case, I simply want to go where things left on and restart again.

I was having problems updating information in my SQL database using my vb.net application, but recently I found the solution. However now I have run into another problem which is shown in the code below:
Private Sub cmdupdate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdupdate.Click
Dim conn As New MySqlConnection
Dim myCommand As New MySqlCommand
'#######
conn.ConnectionString = "server=" & frmLogin.txtserver.Text & ";" _
& "user id=" & frmLogin.txtusername.Text & ";" _
[Code] .....
The exception message is:
Fatal error encountered during command execution.
I don't know if this is simply a syntax error that can be fixed easily, or something to do with my database configuration.

In my project I am trying to capture frames from a camera and trying to retrieve the frame from memory and display the image (Resolution 1280*1024) in a picture box. while doing this I am getting an error stating as below: FatalExecutionEngineError was detected.The runtime has encountered a fatal error. The address of the error was at 0x7a064d34, on thread 0x188. The error code is 0xc0000005. This error may be a bug in the CLR or in the unsafe or non-verifiable portions of user code. Common sources of this bug include user marshaling errors for COM-interop or PInvoke, which may corrupt the stack. I am not getting what this error is. Can anybody please help me in resolving this error and display my image onto a picture box? I am posting the code below:[code]

Presently working a tutorial in visual basic 2010. I have encountered the error " keyword is not valid as an identifier" I have read the definition of an identifier in the beginners section. Although I undertand the definition of an identifier I still am not sure of it when looking at a line of code. The tutorial gives an analogy but does not show examples of identifiers as they would actually apprear in a coding project.

"[Application] has encountered an error and needs to close. We are sorry for the inconvenience. If you were in the middle of something, the information you were working on might be lost."
I can't reproduce this.

Using MS Visual Studio 2010 Express, when trying to debug, the build finishes and the following error below appears. It doesn't seem to effect the running of the program.
The error is:

The scenario is this: VB.net 2003 connecting to access 2003 using Jet 4.0 SP8 and MDAC 2.7 SP1.On a particular client machine with XP SP2, while trying to fill a dataset it crashes fantastically without ANY error message. the exe just disappears from the task manager.I use a Module to launch the MainApp form, if I try to connect within the Module BEFORE calling the:
Code:
dim MainApp as new MainApp
application.run(MainApp)
...the datasets work normally, but if I do it inside the Form_Load (or anywhere inside the form) it presents the previously mentioned fatal crash.I have updated the clients machine with the SP1 for .NET 1.1 with no luck.Now, in a desperate attempt, I have installed VB.NET 03 in the client machine and with the dev env it works fine, but if I try to run the executable from outside, it crashes again. No error message from the exception handling inside the app, no unhandled errors from the framework or the OS, it just vanishes from the task manager.I tried to reinstall MDAC and Jet but the installers find the previous files and won't update with the new ones. Tried also reinstalling .NET framework and the error persists.

how can I make an app that knows when it crashed and why.I had some thinking, and came up with the idea that I'll have a separate process, working in parallel with my app, and looking after it, and know when and why it had crashed.Can I make my app know when an imminent crash is coming and dump unsaved user data, not to be lost?Let's say that I have an app, that need's "GoRun.dll" to work, but it isn't there, so my app will crash, but can I make my app run long enough to download the "GoRun.dll" file from [URL]?(or have a parallel process to do it, started by the original process, that downloads the "GoRun.dll" file and restart my original app)

My ConnectionString is working fine.
I've saved my SQL command in a string as follows: Dim sqlcmd As String = "select LEFT(eventDate,10) from Locations"
Dim sqlreader As SqlDataReader
Then I open my connection and at that point everything is fine.
I can execute the query just fine but the error comes up when I try to fill data into my webapp.
sqlreader.Read()
loc1Date.Text = sqlreader("eventDate").ToString() ---------- This is the line that is giving me the error "System.IndexOutOfRangeException: eventDate"
I just want the date pulled and not the time. get this date to fill into my textbox on my webapp.

I haven't been doing a programming for awhile now. But, I was a VB programmer before. I will be creating a tool to log issues encountered by the users of our system. It will be a web based.

We have a customer, who prints a large number of a batch job to a reporting service. When printing large batches of jobs, occasionally he would get a WebException from reporting services saying "The underlying connection was closed".What is the work around for this? Somebody added this portion in the code [code]It doesn't seem to fix the issue though. The customer still notices the Web Exception when she prints a large job to reporting service.

Im working on a HSD 32 bit data bus to serial converter via a microcontroller. Now first I want to make a sort of data sniffer to read the data bus (32Bit) .All on the controller side is working and the stream of bytes are coming in via RS232 as 4 bytes in HEX like FD,A5,45,8B . I already converted the bytes in Dec and ASCII to determine what is passed true the bus and how fast and stuff.. Now that is all correct and working very well if the LSB (least significant bit) of the 32 data bus is Data line 0 and the MSB (most significant bit) is Data line 31 but if that is not the case I need to invert the 32Bits (like as I would invert the connector on the bus) . How do I best do this using the 4 bytes I send from the micro controller.
Example:
(MSB) 01001000 01100101 01101100 01110000 (LSB)
HEX= 48 65 6C 70
DEC= 72,101,108,112
ASCII= H E L P
I need to invert it with a button to:
(MSB) 00001110 00110110 10100110 00010010 (LSB)
HEX= 0E 36 A6 12
DEC= 14,54,166,18
ASCII= (SO) 6 : (DC2)

I have a fairly simple XML file that I just want to read the data from.
It has 3 levels, root, main section and items. There are no attributes. I want to go to the first main section by name, then read in all the items. The items all are named the same. I've seen this done before, so it should be ok. No writing will be done. Basically this is a static data file
File looks similar to the following:

CODE:
That code works to read the entry data and to recognise the correct data, and the incorrect. However, even if entry is correct, the error msgbox will appear (x times of how many records there are in file), despite being navigated to the menu. Anyway that the Else isn't triggered when data is correct. Also for it to appear just one instead of (x times of how many records there are in file.)
