VS 2008 Form_Load Terminates Despite Commands Left?
Jan 25, 2011
i have a problem: I have a Form_Load-Method which is not doing all the commands in it. It just interrupts and jumps to the "Form_Paint"-Event, eventhough i did not yet paint anything or invalidated any object. The Form_Load-Method is this:
[Code]...
the dashed line indicates the point of termination. the for-loop is simply not done. i tried it with stop points and the last point it stops is the ReDim-part. this can only mean, that the ReDim-Command forces the program to leave the method. but the for loop is never done afterwards. Can you help me? Because i really dont get it.

I have an application which I wrote in vb.net. When the application starts it connects to mysql database online to get some data and once done it proceeds. The problem is at times it gets stuck in the mysql thing, I mean after requesting nothing happens and this causes my program to lock up. Is there a way the program can determine that x seconds has elapsed and it has not got data, so self terminate it.
I tried using timer to perform this action but as the program requests for data, it gets stuck, I mean it locks up and thus timer also locks up and only after task is done everything resumes. I wanted that when the program is about to start request, I can start a timer and determine that x seconds has elapsed, so now terminate the application.

I was under the impression that there was not much difference between Sub New() and Form_Load. However, I found one weird bug...Add a combobox and a label to a form, and the following code:
Public Class Form1
Private mstrOutput As String = ""[code].....
The label text shows that the value of ComboBox1.Text changes between Sub New() and Form_Load.Is this meant to happen?

The application I'm writing requires the user to select a certain directory on their hard-drive (a game directory), which is saved to the Settings. If the directory is not selected, my application can't work. So, when the program starts for the first time, the directory setting will not be present, and I want my application to ask the user to select the correct directory before the application starts (the main form is shown). I used the following code in the Form_Load event of my main form:
vb.net
If My.Settings.WolfPath = String.Empty Then
MessageBox.Show("Please select your root 'Wolfenstein - Enemy Territoryetmain' mapping installation.", "Select W:ET Path", MessageBoxButtons.OK, MessageBoxIcon.Information)
[code]....
It looks pretty complicated (probably too complicated) but I wanted to make sure that the user cannot continue until a valid directory has been selected. So when the user cancels the folder selection, my application should end. If the user selects an invalid directory (it should end in "etmain") it should display a messagebox and show the folder browser dialog again. It should keep doing this until the correct path has been chosen.The problem occurs when an invalid directory is first chosen. The messagebox does show, but it shows behind all other applications! It took me a minute to figure that out, because I could not find my application anywhere, but Visual Studio still said it was running... After finally finding the messagebox behind everything else, it seems that now everything comes up behind everything else! When I click OK on the messagebox, the new folder browser dialog also shows up in the background, etc, etc. If I then choose a valid directory, the application loads the main form in the background...
I thought at first the problem would be the fact that I am running this code in the Form_Load event. A better place perhaps would be a Sub Main() from which the main form would be loaded explicitly (Application.Run(mainForm)). However, I can only select Forms as the Startup Form. If I disable the "Enable application framework" checkbox I can select the Sub Main() as Startup Object, but all the visual styles are lost...?

After dealing with the pain-in-the-____ error "The path is not on a legal form" witch only occured after dragging a file system watcher onto the form, by creating the file watcher in the code. When an event is raised, i have to tell the user what happened. I can do this using messageboxes, without any problem. But, when I wanted the output to be displayed in a textbox, the program terminates without any warning. Here is what my code looks like:
Public Class Form1
Public watchfolder As FileSystemWatcher
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I have a simple vb.net app written using MS Visual Studio 2008 with SP1 and .NET framework version 3.5. This app simply queries a MySQL table into a dataset, makes a csv file from that data and then uses Oracle SQL*LDR to load a local Oracle table. Nice and simple.
This app runs fine on just about any computer or workstation I have tested it on with no issues but when I move it to the workstation it will live on...it shuts down just before it hits the load event. I have tried to capture any errors but so far there do not seem to be any errors generated at any point...it simply terminates with no explanation.
I even went so far as to recreate the project from scratch and still got the same result. this phenomenon only seems to occur on the very pc I am expected to deploy to.
the only thing I know for sure is that it is getting at least as far as the declaration section of the form. Once it has dimmed all objects/variables/etc..it seems to just shut down.

I have this on the form load;
Private Sub frmMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.Visible = False
Me.ShowInTaskbar = False[code].....
Notice: I used "End", to terminate the process.What I want to do is when the last function is called (Delete_AutoReq_PracNo) it terminates the execution of the application.
Reason...I'll schedule this application to ran from MS SQL Server at night. So realistically, doing all the processes I would like it to stop...Is what am doing sufficient to stop the application from running or there is a more robust approach..

I am trying to figure out how to make a .SubString get the characters from right to left not left to right.Say if a user enters 123456789 in text box 1 and I use textbox1.text.SubString(0,2) it will display 12. But, I want it to get 89.I do not want it to get 98, but 89. I tried textbox.text.substring (0, -2) but that just gives an error.So if Gold is entered it gets ld

I got a panel that i am adding labels to. I have autoscroll enabled on it so when they fill the viewable space it scrolls. but i need to put the labels to the left unviewable space(when left scroll is already at 0) The label is placed but i dont get the scroll bars and i cant force it to scroll to a - value.
Is this even possible? Same thing with UP.
Or is the Scroll only limited to Bottom and Right?

I am extremely new to visual basic and it is the first time i have ever tried to program anything. I am currently using Visual Basic 2008 Express Edition which I downloaded for free off of the mictosoft website. Anyhow, to the question at hand: I was wondering how one would use keydown commands in VB express 2008. I have looked far and wide and have yet to find an answer to this. To simplify it to a specifit answer how would I move (or rather, slide), say, a picturebox to the left of the screen by holding down the left arrow key and have the picturebox stop moving after I released the arrow key. By simply seeing how the code is I should be able to do it for any other keydowns.

What I need to be able to do is send a command across a specific network port (eg. 2124) to a specific ip address. I already have writen the recieving code (for the iPhone os) and accepts commands like:
filefound("Name of file",filetype,size)
All this is to be sent in plain text and once received the iPhone will then send a command like:

I have been playing around with VB for a while now, but still need to consolidate some thoughts. I was wondering if anyone could answer this..... Whats the difference between say Form1_Load and Public Sub New() on form startup? The reason i ask is i normally add calling subs to the form load process, but can you add any startup calls to the Public Sub New(), and if so, what is the advantage?

I have a very large table, and I have a sql data adapter to fill a data table. The user is able to change some values, then saves the changes, at this point i just call the adapter update method (I use the sql command builder to get all the commands of the adapter). What I need it's to make some changes to 4 parameters in the update command, before calling the update command, but I don't see how to do this? Before the update itself, I don't have any values, if I set the parameters (I saw the number of the parameters in the debug mode), before the update, that doesn't do anything, I think they get override in the update method...

I have an application in which I save transactions. So I have a datagridview populated with records and i test for changes in the datatable when saving.then i loop through the changed rows and save in the following order:I have a command that saves a wage.then a command that saves interest.I use this to save as a transactiondate:
acccmd.Parameters.AddWithValue("@TransactionDate", tdate.Date + Date.Now.TimeOfDay)
then the other command :
intcmd.Parameters.AddWithValue("@TransactionDate", tdate.Date + Date.Now.TimeOfDay)
but sometimes the code is executing the two commands on the exact same time. Now I have a query that displays a running total and on order for the running total to work properly no two transactions should have the same datetime for a particular person.how can I add a delay between the two commands to ensure the datetimes are saved differently?
