Application Does Not Crash On Runtime Errors

Mar 31, 2012

I've got quite a big application and I've just started noticing that not all runtime errors cause an error.

for example if I call a function that executes an SQL query and the query string uses invalid syntax or refers to a field that doesn't exist then that would normally cause an error at runtime. But it doesn't - as soon as it hits the error the function simply returns to the caller.

If I enclose the code in a try/catch then the error is trapped but, while developing, I just want a good old runtime error but not getting one.

Use The Listview Tool With Check Boxes?

Apr 11, 2011

I am using visual studio 2008. I need to use the listview tool with checkboxes instead of the checked list box as with the ListView the properties can be set that the user can only have one choice.

Problem: I am not sure on the code to manipulate what option has been picked. I want it to output the same as the code below. I know how to manipulate a checked list boxes by the example code below:

If (ChkdListChoice.SelectedIndex = 2) Then
LstDisplay.Items.Add("Spicy Chicken - �3.50")
price = price + 3.5

Tool Strip Menu And Check Box Sync'd Together?

Dec 16, 2009

Ok, I'm a very inexperienced programmer writing my first "non-example" program without step by step instructions provided by the learning material. That said, I am still trying to grasp all the different concepts, syntaxes, tools available, etc. So I wanted someone to take a look at my code and give me some input as to how I can make the code more efficient because I can already envision some bugs that could come up from the code I have written right now.

So I'm writing a program that will have two controls (as of now, which I might think of other controls that might become useful) that will be in a boolean state. I have a checked tool strip menu item and a check box item. I need to have the clicked event run some statements that will either set a textbox's visible property. But my question is whether I should keep the code as it is, if I should create a new module, use a sub procedure, or what is the most efficient way of dong this? Here's my code but I can already see some functionality problems if I decide more controls that accomplish the same task as having to go back and add code to the existing controls. Should I not try to keep the code in a seperate module so all I have to do is change the code getting called in that seperate module instead of actually going through the event code and changing/adding statements repetitively? Anyway:

Visual Studio 2010 - Diagnose Program Crash During Execution?

Feb 15, 2011

My program keeps crashing every time I try to run it on another machine other than my own dev system. It runs just fine on mine but crashes on everybody else's when I install and run it. To make matters worse, it only gives me the generic "[name here] has encountered a problem and needs to close. We are sorry for the inconvenience". So i never can find out why and where it is crashing!!!!

Check For Errors When Running DataAdapter / DataSet SQL Query?

Jul 8, 2010

This is how I update a table using DataAdapter and DataSet in VB using SQL Server[code]...

I know that the Fill method does not make sense in case of an INSERT statement, but I am new to this technology and the above statement does the job and updates the table w/o problems. My question is this: If there was an error (say a duplicate key error) how would I know this in my application? Should I be putting the above code in a try/catch block?

Also, if there is a "proper" method for running INSERT statements using a DataAdapter/DataSet combination that does not use the Fill method, please indicate that as well.

2 Errors Converting C# To VB Code

Aug 15, 2012

I'm converting some C# code to VB.Net, as it's a language I know better, I've got some code that I can't figure out...

Dim mybtn As New ImageButton()
mybtn.ImageUrl = _imgUrl
Select Case _buttonType
Case ButtonType.Backpage

[CODE]...........

This is giving 2 errors:

Me.btnBackpage_Click = Delegate 'System.Web.UI.WebControls.CommandEventHandler' requires an 'AddressOf' expression or lambda expression as the only argument to its constructor.

And

mybtn.Command = 'Public Event Command(sender As Object, e As System.Web.UI.WebControls.CommandEventArgs)' is an event, and cannot be called directly. Use a 'RaiseEvent' statement to raise an event.

Tool To Reformat Code / Specifically Line Breaks

Jan 6, 2010

Are there any tools available for automatically formatting vb.net code - specifically for adding line breaks at a predefined line length? I'm working with a lot of code with long lines (thousands of lines), and manually reformatting it is quite time consuming. I've seen a number of tools for rearranging code into regions etc., but haven't found any that reformat with line breaks.

Cut And Paste Code In VB Express Without Generating Errors?

Aug 5, 2011

I've deleted the original code, but to be specific, when I developed a form using Buttons and Textboxes I didn't place them in any specific order. The result was that as the user clicks the cursor, it would bounce around the page in what would appear to be a random sequence, but in fact was going to the next button/box in order of how it appeared in the code section of the form. Naturally, my first inclination was ..... OK, that's how it's going to be, I'll just cut and paste the code in the order of how I want the cursor to move. What happened was I generated several errors and the file would not compile. I can find no information on how to properly cut/paste code sections without generating these types of errors. BTW, I did try the focus() function and it did direct the cursor to the appropriate box, but it also only allowed 1 character to be entered in the textbox and summarily directed the cursor to the next box.
