I have a form that on load keeps closing without any errors... I have no clue what it wrong with it. How can I record all the lines of code being executed so that I can find out why it is closing. There are no errors or me.closes.
View 3 RepliesHow do I make a program run only when it is executed with a command line? For example, if you press WINDOWS KEY + R, and then type in
"firefox.exe -profilemanager"
It will open up Firefox's profile manager. How do I make my program do that, except, if it's command line is "program.exe -letmein" it'll open form2. And if it's opened manually, (by doubleclicking or anything else) it'll open form1.
How do i find the record pointer AFTER the select statement was executed. I am excuting the following code, but i need to move my pointer to the found record
adp3 = New OleDbDataAdapter("SELECT * FROM Recipe1 where RecipeName = '" & RecipeName & "' ", con)
adp3.Fill(dt2)
ListBox1.Items.Add("RECIPE NAME : " & (CStr(dt2.Rows(0)(UCase("RecipeName")))))
My problem is that some code I enter will not be executed. Here is an example of my Form Load event. If i debug the code then the first two lines are executed. The MsgBox won't be executed though. or anything else after it. My programm does run perfectly. But i cant make any changes anymore It's driving me nuts, I don't have the faintest Idea what could be wrong. I sent the code to a friend and he isn't having any problems at all. We both use win7 64bit (he has ultimate, i have home) [code]

I have a hashtable of a class that contains a timer. When this timer elapses x amount of time, it calls a subroutine within the class. This subroutine calls several other functions and subroutines and then its done until the timer elapses again. Now one of the subroutines updates a label on the form and i can see that happening when its supposed to. There is another subroutine that should be updating another label but it is not. I believe this would be a simple correction but when i set a debug point on the routine it does not work. I'm not going to post the code for this as it is hundreds of lines of code and its probably just a configuration in the IDE that got changed somehow.
I run break points around the rest of the project just fine, even in other classes that use timers. Does anyone else have this problem of code being executed but not being able to debug it?
I have a project with 2 forms. I need the code to be executed on one form first, which is why it is run first, then I want to hide it and just display the user interface form. I have the following code, it makes both forms appear, but I only want the user display form to show: [code] I call both these subs in the frmLoad of the Processing form.

Is it possible to stop a Sub from executing its code when you, for example, click a button?

The documentation for an API I am using explicitly says that I need to call close() on an object when I am done with it. I would also like to log something there.I understand GC, might not happen at expected time, etc. etc. I still want to implement some code at cleanup.I read that I need to Override Finalize() to do this.I wrote a console app to test and it looks like it indeed works.However, this does not work with windows forms. I put a break point and it never gets hit in the Finalize method.How do you add some code to be executed at cleanup time for a window form?Here is my console app test:
Public Class Foo
Public Sub New()
Console.WriteLine("In Foo Constructor")[code]......

I have a backup script i made in VB. part of the code im having trouble with:
HTML
code:
Now this code is executed when a button is clicked, if the folder does exists, it displays a message and continues the backup. however if it does not it displays displays "does not exist box" then i want the application to close.
I played around with the application.exit commands but it seems like the code just skips over it, and continues to try and backup the data, then errors out. how do i make the application close, if the dir does not exist?
How do I wait until the report has finished rendering before the rest of the code gets executed?

But then wondered if I could reduce this to:

...rest of code...
End Sub
will the "New" bit only be executed once when the function is first executed but in the next call, it will already exist.

I'm trying to understand how this code work step by step but I'm confusing How the code work when executed from first step to last step?example: when I set obj to age = 39 . is the first step is checked if the variable in m_Age or checked in Property Age

View 1 RepliesWhen I started to work on this new project in vb.net 2010, I put many breakpoints to try to understand the execution order of the project, only to find it in vain. Step into command F11 should work correctly according to Visual Studio 2010: Step Into Property/Function(F11) doesn't work as expected. But I when I pressed F11, I found the code is jumping from one place to another based on breakpoints, not line by line or step by step.To give an example, please see the code below
Me.tcData.Alignment = TabStrip.TabControl.TabAlignment.Bottom 'line 1-breakpoint
Me.tcData.Dock = System.Windows.Forms.DockStyle.Fill 'line 2
...
Me.tcData.TabsDirection = TabStrip.TabControl.FlowDirection.LeftToRight 'line 3
[code]....
When I press F11 at line 1, it goes to the property 1. After it returns, when I press F11,it goes to property 3 directly, without accessing the code in line 2 and line 3.I do not understand why the code is NOT executed step by step by using F11. If I put breakpoingts in line 2, then line 2 is executed.So it seems to me that the showed execution order is based on breakpoints! So if I put breakpoints at different places, the showed execution order would be different! Thus, it is impossible for me to really understand the execution order.
Basically I'm trying convert the following....
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

When reading and writing data to an XML file, in XML code, through a VB application, how does one go about commenting out a specific XML code line? From what I've gathered the original <!-- and --> tags aren't compatible. So what would be the VB alternative? Or is it just not possible to comment out a line of XML code using XML code through VB?

View 4 Repliesi have one project (let's call it project1) that is going to add properties to another project's class. The thing is I wanted to make it automatically. So in my project there are two lines of code which I want to add at the bottom of the class.vb or class.cs in a project called project2. Is it possible? If so, how?It is a data access builder software which after adding some new columns to our database we use it to generate its properties and its parameter to be added in BLL. Since we do it often (changing our database structure) I did not wanted to copy data from data access builder software and add it to project2 manually.
View 3 RepliesIf I add let's say 1 line at the beggining of a method, if I set a breakpoint through Visual Studio on the first line, will it point to the first line or the second? If it will flag the wrong line, is there anything we could do when editing .exe files to ensure a regular debugging session later?Isn't there something like setting line x to be Y? I remember seeing something like that somewhere, not sure if .NET related or not.
