I am using VS 2008/VB with Access 2007. I have 2 forms that I use to create entries. In the first form (fomr1) I select the type of entry which opens the respective form (form. In form1 I use some code to read through a oledbreader the id rows and get the max value in that column. I take that value and I add 1 to it and then assign the value to a textbox in form2. The whole process worked fine until today which gives me this exception "An error occurred creating the form. See exception.innerexception for details. The error is Object reference not set to an instance of an object. "

i am pulling together a cash register that will allow both bar code product entry and manual key entry.imagine if you have a tin of beans in front of you, in a small corner shop they would probably type "47" and then hit "Produce". Fairly straight forward as I have the button Produce to act upon my code and update my salestrans.mdb but,if you scan the bar code I want the same form to handle both 'real' actions, (i assume that keyboard emulation barcode scanner includes "ENTER" after providing 13 digits)....
Q. in perhaps a long winded way i want to know how to kick off an event based on the "ENTER" key being activiated by the barcode scanner)?i do not want to have to hit any buttons if i am scanning bar codes.

What is the code for ignoring the case of an entry while checking to see if the entry is correct or not... (i.e. in a flashcard program... given definition, asks for the name) I don't want the case of a character to affect whether the answer is correct or not.

I am trying to make a program with a bar code reader for the first time. I am programming with VB 2005. I want to differentiate a bar code entry to keyboard entry. My questions:
1. Does bar code reader generate a keydown (or keypress) event for each of the digits of the entry? For example, if the barcode read: 1234567890, does that mean that there will be 10 keydown (or keypress) events for that single barcode that was read?
2. I have read from the posts that the best way to differentiating keyboard vs bar code input is to analyse the time between keystroke (for less than certain number of milliseconds).

I am developing an FTP program which: Watches a folder. If a new file is dropped there then upload it. Tells user if uploading and when complete. All the above works, however I wan to add the items to a listbox that are being uploaded. So if I dropped 3 items there it would look like :
Upload Listbox:
cake.jpg
myExcelFile.xls
woot.docxAnd as each one is done, or new files are added it removes them or adds them.
I tried using que, but with no luck as the program just hangs whilst it uploads. So I had a search and looked into multithreading and I tried to implement it, but I can't get it to work as it gives me some 'delegate signature' related error message as you can't pass in values when trying to use 'AddressOf'.
Here is my code for the The .created sub:
Public Sub FSystemWatcher_Created(ByVal sender As System.Object, ByVal e As System.IO.FileSystemEventArgs) Handles FSystemWatcher.Created
'if any file created add fullpath to the listbox
ChangeLog.Items.Add("Created: " & e.Name)
QueueListBox.Items.Add(e.Name)

I am stuck on a homework problem and was wondering if anyone could help out a beginner.The question reads:Calculate the amount of a server's tip given the amount of th bill and percentage obtained via input dialog boxes. The output should complete sentences that reiterates the inputs and gives the resulting tip.
here is what I have so far:
[Code]...
It works fine if I input the tip percentage as a decimal, but I need to be able to input a whole number for the percentage, and in turn, output the correct decimal. I'm sure this is a pretty easy fix,

I migrated an application from Vb6 to .NET and there are still a few bugs to fix.One of them is when I want to edit a record, the inputs should have been populated with the coresponding data from the database. Instead, only the drop-downs are populated, the text inputs are blank.

I have a recursive function that causes a stackoverflow for big inputs. So I want to enlarge my stack. I have never worked with threads so maybe I'm doing something wrong but when I try to make a new thread, the description for the second argument (StackSize) says that if I use a stacksize bigger than the default one, this argument will be ignored and the default size will be used. How to increase the stacksize? Or how to create a thread with a bigger size than the default one?

working with Adobe .pdf files. I have an Adobe .pdf template that allows the user to enter text into different parts of the .pdf template (such as name, address, etc.) I have been developing a VB.Net program that is made up of a set of user forms. I would like to be able to have data that the user enters into textboxes on the VB.Net user forms write to specific areas of the Adobe .pdf template on the click of a command button. I have searched MSDN and Google but I have been unable to find any information on this particular task. If it is can you recommend a MSDN type article or any articles/books/message board posts that provide guidance on how to proceed with something like this.

I have several text boxes that I will input answers into and I want them to catch the values if they are incorrect or correct.
Example: the user will input a Letter for the answer, A or a, and I was curious to how the correct input can detect if the answer is correct.If the answer is A B C or D then no message should display but when it's some other value this message will come up.How do I use true or false in this code?
Dim dbl1 As Double
dbl1 = CDbl(txt1.Text)
If dbl1 Not 'A OR a' Then
'Display message
MessageBox.Show("Enter A, B, C, or D")
