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.
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 turn on my computer and appear this " Ixdn MsdMon.exe-fatal error CLR error: 80004005 the program will now terminate" and the computer runs very slow
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]
I am a fresh graduate and I am working now as a developer By the way, I am not the one who developed this tool, it's the previous programmer and they gave the project to me to update it however, when I try to run the application in my local computer I am getting this error:

How to make a program wait till a shell command finishes? For example:[code]In this example the line "Finished" is first written and only after then the shell function starts. How to start the shell function first, and only when it has been finished write the line "Finished"?
When I do it via VB express, it is clumping the code together. For example
Threading.Thread.Sleep(5000) SendKeys.Send("enter was entered ") Threading.Thread.Sleep(5000) SendKeys.Send("double tab was input ")
Instead of pausing for 5 seconds, typing the keys then pausing for another 5 seconds, it pauses for 10 seconds and then immediately types the input. I tested this on notepad.
How do I replicate the sleep feature in VB script into VB? There appears not to be a sleep feature in VB Express 2010
I have a client application that has been in use on about 14 workstations for nearly a year now. on the admin side the old app works correctly but the new one comes up with an error stating a column (Job_ID auto increment primary key) in the database does not exist when inserting a new job record yet it still adds the job to the database. all information is correct. The estimation side does not come up with this error and all computers in both departments run the same exact application installed from the same disk. all issues seem to be related to the jobs table only. But the same workstations with the column not existing error on admin side have a different setup on the network and will not allow a desktop icon to be created by the new application or manually.
im wanting to make a game that will teach users about server security systems. By programing a game that will act like you are in the real field or in real life right now how malicious users would go about hacking a server that way you can secure your server in the future.
But what im having trouble with is getting the whole setup its basically going to be a text based game. on startup i have a warning message pop saying this software is not meant for illegal use and upon hitting ok the other software pops up with a logo and to the left is options
Shell, Hack Tools, Shop, E-Mail, CPU Now what i want to do is when the user clicks Shell a somewhat shell like system would pop up giving you base line stories to do. But how would i go about making the user commands for example if user typed in
[code...]
So the main question here is how would i get the commands to work? And then lets say your first objective is to find a random .txt file somewhere in the server . User would have to type

I am checking to see if a textbox contains a number, or is null. If it is non numeric or null a message box appears asking the user to input the proper value. When the user clicks OK on the msgbox the program will continue to execute the code. I want it to stop executing the code and revert back to its default state as it would be if you just opened the program. What is the command for doing this so I can add to the if statement?
Dim numCheckV as boolean numCheckV = IsNumeric(Vinput) If numCheckV = False OrElse TextBox1.Text = "" Then MsgBox("Please enter voltage!") End If
I've just finished installing VS2010 on my computer. I have a project I built in 2003 that I'm trying to open in 2010. It went through the conversion process and generated this error: System.SystemException - The type library importer encountered an error during type verification. Try importing without class members. : System.MissingMethodException - Method not found: 'Void
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.
I have completed and distibuted a VB.net (VS 2008) winforms application to numerous users.
One user reports the following error when opening the application:
"[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 am executing a SQL Server 2000 DTS package using C# by following the code from this article [URL]. once the package is executed I am looping through each step to find out if any step has failed and get info about error if it has failed. I also use this information to find out if the package has succeeded or not (package failed if anyone step has failed).
Is there a command that will stop the execution of my program?
I have a service that is processes an exchange account via telnet every 10 minutes. During one point of execution the application could possibly have a response from the telnet session when there are NO e-mails in the folder, which would look something like this[code]...
So is it possible for me to just stop my application at that point since there's no point in continuing if there are no e-mails in the account?
I got a stored procedure that reads a table and insert those data to antoher table. That's the way how it works because the first table imports data from excel using a package with SSIS.In EF4 I imported the SP and create function import:This SP has 2 IN variables and 2 OUT varibales.The IN varibales are parameters and OUT variables are a message and the number of records created.[code]
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:
An exception was encountered while constructing the content of this frame. This information is also logged by running the application with the /log parameter on the command line, which stores results in "C:Documents and SettingsCorkyApplication DataMicrosoftVBExpress10.0ActivityLog.xml".
Exception details:

I can't find the "ActivityLog.xml" file the message references.
I am a newbie and am trying to open a table in SQL Server 2008 table from Visual Basic using ADO and its throwing up a weird fatal error. The error message is:'A fatal error has occurred and debugging needs to be terminated. For more details, see the Microsoft Help and Support web site. HRESULT = 0x80131c08. ErrorCode: 0x0' The code I am running at the time is:
I am trying to get this contact form to work, but I get an error message saying: "failed to send message". The problem is the section of code near the bottom of the page where it executes this line of code: MailObj.Send(myMessage)'ve put dummy credentials in the snippet below but triple-checked my smtp un/pw and cant figure things out.
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)

I imported an app from vb6 to vb.net It works fine. It has one axmsflexgrid control. Now I want to add another axmsflexgrid control in the same app. I tried to copy and paste from one frame (groupbox) to another and got this error:
"An error occurred while processing this command: Exception from HRESULT:0x800A018A (CTL_E_GETNOTSUPPORTED)"
An inputs on how would I fix this? Or just make a new axmsflexgrid?
