Dynamically Generate Subroutines?
Mar 20, 2010
To detect 'death of player' I am using the mouseleave event of my picturebox background (background1). Unfortunately this triggers both when the mouse enters an 'evil' and the 'points' and ends the game without the player being able to collect points.
The obvious way to solve this would be to swap detection to entering evils.
Unfortunately I am dynamically creating my 'evils' and do not know how to also dynamically create subs to deal with MouseEnter. Here is my code for generating the 'evils'
'The number of evils (asteroids)
Dim evilcount As Integer
'A count for use with comparison to evilcount

I've done asp.net exclusively so long, and now I have to convert a small web app to a desktop app.
At one point in the web app, I dynamically generate a table of data and add it to a placeholder control.
I'm not sure how that would be done on a desktop app. Can anyone suggest a control or 'windows' way of doing that.

I would like to generate the checkbox list dynamically.For example against the list of employees(rowwise), provide the list of check box options (columnwise), the selected items will be stored in the database against the each employee. Since i am the new to .NET your guidance will help me to complete the task.

I have an error panel that is subbed in to a page if an error goes wrong to gracefully handle and display errors.Currently, I am just appending the error messages to a string and pushing that to a label. If you have multiple errors, this gets messy.I'd like to push each error to a list item in a bulleted, unordered list.How can I dynamically generate, from a vb codebehind file, new list items inside of an undordered list element?

I recently added three subroutines to a form, and as a result of adding only the three subroutines, I have noticed some weird behavior in the form and I can't pin down why these three subroutines would cause it.

I'm struggling with an event related to my communications class.I'm calling a 'DataChange' function via event handler any time I receive new data over my serial connection. I then proceed to load that data into a DataGridView, perform some formatting, etc for the users. I'm getting a ton of problems due to the frequency at which the DataChange event is called and seems to steal the focus out of othert subroutines and functions mid-process.For example, I'll attempt to transmit data back to the serial device. After I format the data, but before I can actually call the Send function from my library the focus is directed back to DataChange and I never actually transmit my data.
Is this a problem best addressed by threading the DataChange related routines, unhooking the DataChange event before a function or routine then rehooking, or is there some basic principle I'm not implementing.

The Visual developer express outline provides hide/plus-minus signs throughout the HTML code, and it does this for Class's, but not for my subroutines in an ASPX file.Is there a way for it to do this, so I can reduce subroutines I'm not working on at the moment? I know I can highlight areas and hide, but it's kind of clunky to do quickly through many subroutines if I have 2k lines and a hundred subroutines.

I have 2 arrays X(n) and Y(n) where n can vary programmatically, no set value. I want to pass these two arrays between two subroutines.
Sub sub1()
...
call sub2(X,Y,n)
end sub
sub sub2(x,y,n)
...
end sub
I want to know how to prepare the arrays for the "call sub2" and how to extract the arrays in "sub2".

have been writing code to replace an old Fortran program. The Fortran program had very organized subroutines which could be called from anywhere in the project. Most of these were relatively small and left a small, easily followed main routine. I'm converting over to VB.net and when I write the subroutines they are all on the same form. Wading through 50-100 subroutines on one form is going to be messy.

I am trying to convert an algorithm to use them in order to save memory. However, I am struggling to achieve error-free code while using "Strict On".
Here is a basic version of the code I am attempting to use.
Code:
Option Explicit On
Option Strict On
Module Program
[Code]...
It works when I do not use the Strict option. How do I improve the code to compile error-free?

I find myself calling functions from lambdas frequently as the provided delegate does not match or does not have sufficient parameters. It is irritating that I cannot do lambda on subroutines. Each time I want to do this I have to wrap my subroutine in a function which returns nothing. Not pretty, but it works.
Is there another way of doing this that makes this smoother/prettier? I have read that this whole lambda inadequacy will probably be fixed in VS2010/VB10 so my question is more out of curiosity.

Working on my major project for my last year of school worth 30% and am having issues with getting screen elements (buttons, labels, picture boxes, etc.) to update before or during a sequential sub program or function.
For example, I have a series of picture boxes that require to be clicked on to activate certain commands. Here is the code for one of the picture boxes, picX3Y0, when it has been clicked on:
If picX3Y0.ImageLocation <> imageFolder + hiddenImages(3, 0) + ".png" And imagesSelected < 2 Then
If x1 = -1 Then
x1 = 3

As it is right now I have a bit of code that kind of looks like this (a little paraphrased but Im sure you get the idea)[code]I thought for sure the above would work but it still seems that I am missing something, when I open the excel sheet nothing was printed. This would cut down the lines of code that I have in half easily, so I would love to find a solution for this [code]But the excel sheets still do not update with the new information.

I'm having trouble with passing an array between subroutines
I have an array called "lines" which is loaded from a text file and then edited according to a series of checkboxes within one subroutine. Each line in the array is essentially a line from the text file
I then need this array passed to another routine so that it saves to a new text file once the save button is pressed. (in this case just the top 5 lines)
At the end of the section that creates the array i have placed this
From File Edit
Call Savefile(Lines)
The section of code below is from the section once the button is pressed
Save Code
Sub Save_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Savebutton.Click
[Code].....

I'm trying to communicate through a serial port with separate subroutines for establishing the connection to the device and handling routine messages. I'm able to establish the connection, but reference to the COMPort in another subroutine fails with a message that the port is closed. I can successfully communicate using COMPort.Write commands within the connection subroutine, so I know that works. How do I pass a reference for the comport to other subroutines?

Visual Studio 2008, Standard Edition VB.NET I have only limited experience using the background worker, and all that I've done with it thus far was fairly straightforward and worked fine.
I am now looking to run a process in a background worker which calls various functions and/or subroutines, but of course it generates an error indicating that it's on the main thread (or something like that - I don't recall exactly, but that was the crux of it).

The problem comes when n can be changed in sub1 say a textbox. How do you transfer an array of variable length between subroutines?

My project is built in VB.Net.Many times I find that Visual Studio has added subroutines to my code files even if a subroutine of the exact same name already exists. This can cause debugging nightmares as the new empty routine seems to override the correct routine. I think this can happen if I double-click on a control in the form Design view, but I try not to do this.Is there any way to turn this off?
Example:
Hand entered
Private Sub TS_Main_View_Network_Click Handles TS_Main_View_Network.Click
System added:
Private Sub TS_Main_View_Network_Click( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TS_Main_View_Network.Click
I guess that the system adds the second routine because the argument list (which is unneeded but may be required) list is missing from the first routine.

I have been learning vb.net for about 6 months now and I red few books about basic visual programming as most to them have information about the basic concepts like what is Object oriented programming, subroutines, functions ,inheritance etc and bit about ADO connectivity to database. Having said all that I think I have good concepts about all these things but now I want to proceed further but can't find appropriate text books or online tutorials.

I am very familiar with modules from my time with VB and my other programming, but what is the most commonly used practice and the best way to go about this for a website application with ASP.NET? Say I have multiple pages (in multiple directories; some in the root directory, some in child directories from the root) that will call the same set of functions and subroutines, how do I go about putting this reusable code in a place where the pages and their respective classes can call the functions/subroutines?

Several times while debugging a VB.Net program I have found that continuation lines are missing from a subroutine designed to handle an event. The continuation character "_" is there but the following line is missing
[Code]...
The first few times I figured I had made some editing error, but this has happened 3 times now, always in the same way (different subroutines but same place). As far as I can tell, no other continuation lines have changed. Is this a bug or some feature I have missed?
