Dec 13, 2009

Sometimes when my server is down or busy, I get an error saying "connection timeout" while connecting to MySQL. But with the error the program also crashes.

I use this,
Dim connStr As String = "Database=mydatabase;" & _
"Data Source=datasrc;" & _

No Connection With Database (possible No Internet Available) / It Should Display An Error Message

Aug 1, 2010

I've added a database to my application with 2 fields:"ip" address and "started" that holds the number the application was started from that specific IP.I want to upload the database to my site hosted at google.sites. When the program is started it should make a connection with the following cases:

1-no connection with the database (possible no internet available) - it should display an error message

2-there is connection, the IP is not stored on the database, it addes the IP to the database and the field "started" with the value 1

3-there is connection, the IP is stored on the database, it increments the field "started" by 1

InputBox And MsgBox Button Handling?

Dec 29, 2005

From my input box, if cancel is clicked, I want to exit the sub. Here is my input box, but how do I create an if..then to find out if Cancel was clicked and then stop running the macro?

myLPS = InputBox(msg, title, vbOKCancel)

Second thing, I have a message box that asks if the user wants to continue with Yes & No buttons. But, if I click No, it just keeps executing. I want it to execute from the end of an if..then if No is clicked. Here is the function called and my if..then:

If CheckOK(MLSName) = vbNo Then GoTo ClickNo ' this is at the end of this big if statement - ClickNo:
Public Function CheckOK(MLS As String) As VbMsgBoxResultDim message As StringDim title As Stringmessage = "Create Task for: " & MLS & "?"title = "Continue..."Result = MsgBox(message, vbYesNo, tite)End Function

Error Handling When Using VB 2010 Express?

Jun 3, 2012

I used the following code(with bug):

Code:
For n = 0 To 100
If saveLine(n).Substring(0, 8) = "heading:" Then
cboSelect.Items.Add(saveLine(n).Substring(8))
End If
Next n

The For loop only ran 5 times. It turned out that saveline(5) was shorter then 8 characters, so I changed the code which solved the problem:

Code:
For n = 0 To 100
If saveLine(n).Length > 8 Then

[code]....

VB 2010 neatly exits the for loop when the bug occurs. In this case it was easy for me to pick up the bug, because the combo box was not properly populated. What if it was not obvious that the for loop did not complete? It is quite scary to think that bugs like this are not displayed at run time.

Dec 17, 2011

I am trying to add some error handling for AppActivate if any error occurs.I initially tried using a try statement and cancelling the sub that calls the function where my AppActivate code is, but that didn't work.I have tried looping it, changing values and everything I know. I have Googled and nothing :S

Handling Application StartupNextInstance Seems To Trigger Internet Access Event?

Feb 7, 2010

I successfully coded MyApplication_Startup and MyApplication_StartupNextInstance to give my single-instance application access to the command line. It works fine. if the application is not running and the user double clicks on a filetype associated with my application, my application starts up and reads in the file that was double clicked on. That's fine.

However, when the user double clicks on another file (same associated type) when the application is already running, I then (and only then) get a warning (from McAfee in my case) that my application is requesting access to the internet. I simply click OK to allow access, McAfee goes away, focus shifts to the original instance, and that instance successfully reads in the second file.

If the user then double clicks on a third file when the application is already running, focus shifts to the running application, it loads the third file, and the internet access warning DOES NOT appear. Same with all subsequent cases.

Any ideas about why the sudden internet access warning is occuring? In all the startup and load events, I do not do any internet related things. Much later, the program will send an email, but that code is far removed from Startup and Load things.My only idea is that perhaps because I have "awakened" the normally hidden ApplcationEvents.vb file (by putting some code in there), maybe I have triggered some sort of handling of the MyApplication_NetworkAvaialabilityChanged event, even though I make no reference to this event anywhere.

Before I added the command line handling stuff, I noticed that the internet access warning would occur only once for each new build. Susequent execution of the same build would not trigger an internet access warning. So now it is as if the handling of the StartupNextInstance event is simulating starting up a new build for the first time. Weird.

One more thing. I am not deploying this over a network. I am making a simple .exe by selecting Build from the MVS 2008 menu, then running the .exe by double clicking on it from Windows Explorer. I am using Visual Basic 2008 Express on Windows XP.

The function checks for the input only the digits.

Internet Connection Best Practice?

Dec 8, 2010

What is the best practice way of detecting internet connection?

From Windows Vista onwards, a status is set in windows that is displayed in the task bar. However, I cannot call this function/api/whatever, since some of the client pc's are still on xp, and only due for upgrade in 18 months.

so do i use and request something like [url]... to try and see it it works, and on the catch block set the return value to false, or is there another way?

Second part of this question, If no network connection is available, I can use [url]... to dial a connection. Will this use internet explorer's settings, or dial the connection marked as default in DUN?

Can't Seem To Establish A Connection Between My Two P2P Applications Over The Internet

Sep 14, 2010

I just can't seem to establish a connection between my two P2P applications over the internet(LAN works perfectly fine).

I have tried the following.
- Disabling Firewall
- Changing Port

The only way I can establish a connection is if I'm connecting to the same computer using the universal IP or the local. Does anyone have a fix for this? Oh and here is the error that I receive when trying to connect over the internet:

System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it 255.255.255.255:8787
