VS 2010 AppActivate Error Handling?
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
Here is my I have removed all the error handling I tried to implement, however, this commented msgbox I would like to be included (that is, possible to execute) in any methods you present.

the name pretty much says it all, I need a more reliable code then AppActivate that does the same thing. I need it to activate a program I tell it to, perferribly without calling the process id.

I am working on a tournament host tool program for a MyLeague game league that plays on Pogo. I am wondering how I can select the chat box of pogo games after I use AppActivate. I am using this:
Private Sub Button11_Click(sender As System.Object, e As System.EventArgs) Handles Button11.Click
AppActivate("Username in Bridge")

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

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.

In the Catch of Try-Catch there are the following two properties:
e.Exception.Message.Count()
e.Exception.Message
Does the .Count mean there are multiple lines in .Message? If not, what is the .Count used for?

I have an object, say Order where if an error occurs, it raises the ErrorOccurred event. If I'm running some code in say, the codebehind for a .aspx page with an public Order registered as WithEvents and I want to check to see if an error has occurred before I run more code, how do I do this? I can't simply check theOrder.ErrorOccurred. Do I have to create a local boolean flag that switches over in the event handler (OnErrorOccurred)?
Example:
Public WithEvents theOrder As New Order
Public Sub DoStuff()
theOrder.DoSomething()
If theOrder.ErrorOccurred Then

What error handling should be used in VB.NET? Should one use the "On Error Goto ErrorHandler Exit Sub ErrHandler ... End Sub" pattern or should you use the "try {... } catch {...} finally {... }" pattern?

Ok, so I have set my form as the parent of a 3rd party application.Appactivate works when the 3rd party application is not a child of my form.It would appear that if the application is not on the taskbar (A non taskbar application) appactivate does not work.

I have a window that I need to activate and the window name does not work in AppActivate("WindowName") because this does not work with partial captions etc... and the window name will be different depending on user. That being said I am able to use "GetwindowhandlefromPartialCaption" to retrieve the # value of the window name or handle. Is there a way to convert this or extract the name from the handle ID to use with AppActivate?

I am just doing a bit of error handling. I am just check to make sure that a user has selected an option within a combo box (named cbtitle1) and if option has not been selected throw an error message to tell the user.this if statement is within a save button which once a user click save this error checking runs first then if combo box has an option selected the save goes ahead else it throws an error.I can stop the save function OK but I wanted to put a error icon in with the message box but I get an error when I add it.[code]

Obviously error handling is a major factor in making a good application. If a error happens letting a user know what has gone wrong.But some times error handling may(i think) not be needed. Example.
Private Sub RemoveCheckedl()
Try
For Each Item As ListViewItem In lst.CheckedItems[code]....
also when error handling it's could to think about what type of errors could be made.
Catch ex As Exception
MessageBox.Show(ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error)
even though this catches the error and displays a msg, it may not be a great message for the user so he/she can understand.

I am working on an executable to load set of data into databases.I will be running it as a windows service. I will be doing several different checks to see if the fields exists in the incoming files. When i do the checks using if statements.I would like to stop processing when a major error occurs or when any thing is interrupted Like say windows crashed. I would like to create an error file with the error message in it for that particular file. I would be monitoring error folder everyday to check if there are any errors.

When debugging a program, instead of doing this on EVERY piece of code:
Try
MyFunction()
Catch ex as Exception
MsgBox(ex.Message)
End Try
Is there a way to apply that to everything error I encounter without writing it on every function/sub/etc?

I am using try..catch for error handling. I am getting the message displayed as
messagebox.show (ex.tostring)
But it gives very long message.Is it possible just to get only the actual error or I could give my own modified message, based on what ex contains?

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).

I am looking at implementing a Web Service API for our product. I have figured out how you go about the general architecture/fault handling within WCF. My question is a more general one of how to design the overall error handling system. For example I have a method called SaveCompany (companyobject). Each company name needs to be unique. Say you tried to save a second company called "ABC Inc.". Would you expect to get back a fault named "DuplicateCompanyFault", or would you expect to get back an error code, or something else? I guess the root of my question is would you prefer to receive faults to handle, error code, or some combination? These services are going to be consumed by multiple different entities outside our company on multiple non-.NET platforms.

We are developing an application for our shop floor. This program will be tracking material through the shop and we need to capture any errors the program generates, but we don't need to stop the program for all errors. I have some code to do a screen capture and put it in a database with exception.tostring data for debugging.
What we would like to do, is create an exception from the base class, but provide additional properties to allow us to set a severity and a user friendly error message. I would like to encapsulate this in a class that we would call in the catch of a try/catch, set the properties on the class, have the class record the data to the database, then raise the exception to the main program to display only the user friendly message and severity. The main program would then determine the severity and based on the severity stop the program or just display a discreet msg and continue to process.
Does anyone have an example of a custom exception class derived from exception that does something similar, or if I heading in the wrong direction, does anyone have a better solution?

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. My question is how can I prevent crashing, it would be better to show a msgbox when this happens. (visual basic 2010)here is a screenshot of the error
I use this,
Dim connStr As String = "Database=mydatabase;" & _
"Data Source=datasrc;" & _

I just need a good nights sleep, but Im simply reading through a file (2010 data) and for selected teams, accessing the corresponding data for the previous year (2009 data), which is held on a separate file. (I painstakingly input all the 2009 data manually)
ds1.Clear()
cmd1.CommandText = "SELECT * FROM Teams WHERE Team = ?"
cmd1.Parameters.Add(NewSqlCeParameter("Team", (ds.Tables(0).Rows(x) ("Team"))))
cmd1.Prepare()

plain how error handling scope works. What I mean by that is if I have a sub called ImportData and in there I have a for loop to go through a list of files and in the for loop I call another sub routine called CheckData. All have catch error in. If a sub has a catch error in where does it go from its call.
Private Sub ImportData
Dim iLoop as Int16
Try
