View 6 RepliesI have Visual Basics 2008 express and I tried to make a autotyper, so this is my
Button1: Timer1.Start
Timer1: Timer2.Start
Timer2: SendKeys.Send(Textbox.text)
Button2: Timer2.Stop
So it was my first try ever with VB and it kind of worked... Only 2 problems;
1. Button 2 doesn't really work, I have to click it really many times, then go to a different window, then click it really many times again, in the meantime it keeps on spamming
2. How do I make my autotyper press enter every single time after the textbox message was typed?
I am trying to make a list, separated by a comma, of entries from a single column in a SQL database. I have been spending the last several days searching for a way to do this, but every thing I found either didn't work, or wasn't exactly what I was looking for.
The query will pull all the email address that are not null. What I need to know is how to take the result of that query and make it look like this:
email0@address.com, email1@address.com, email2@address.com, etc, etc, ...
I feel like I should know this, but for the life of me, I can't remember nor can I find it in any of the textbooks I have.
I am using Visual Basic 2010 and SQL Server 2005. I also have access to Visual Basic 2005 if needed.
how can I detect if press Enter in the Textbox Change event and not in Textbox Keypress?
View 3 RepliesI am building a POS app with a barcode scanner that auto-return( = pressing keyboard's enter key) after each scan. I need to handle this event by processing the scanned barcode against my items database table. I am using the scanner in keyboard wedge mode so I selected a textbox control to collect the scanned barcode, clear cache and ready to collect another barcode data from scanner. I have tried all the changed events I know on text boxes but I dont get the desired result, I cant clear cache and my cusor wont remain in the text box! I have used the keypress, keydown, textChanged and Enter methods, in most cases I got only the first digit in the barcode.
View 2 RepliesI have a multiline text box which is used to enter barcode numbers into. I have a barcode scanner and all the barcodes will end in L2, L3 or L4. Once a barcode is scanned in I need VB to detect either L2, L3 or L4 then go to a new line and repeat. Where I can start to accomplish this?
View 4 RepliesI am using Richard L. Grier's Enhanced Serial Port dll to read input from a serial port barcode scanner I notice that the datareceived event fires only once per barcode scan, but the delegate sub fires twice per barcode scan. Once for 1st half of Barcode , 2nd for 2nd part of barcode This makes it hard to capture the full barcode so it can be passed to routines in my vb.net 2008 windows application In Richard's example 'Test Enhanced Port' program he sends it to a textbox using .selectedtext and it works fine Richards Delegate code ......................

I am a student and I am about to make a program that will use a barcode scanner well ofcourse to scan a barcode. My problem is i don't know what library to use and what certain things i need to do so that when i am going to scan a barcode it'll be something like show it on a textbox and pull something from the database. i've actually research some. i've seen mscomm1 (not so sure about that) and POS for .net (haven't fully understood its use) were those will help me develop my program?i have a metrologic ms9520 Voyager barcode scanner. and i am going to create a program for it in vb2005.

I'm trying to create a "LOTTO" number picker, but I don't want to have more than one TextBox. And I also don't want duplicates in that single textbox. The program randomly picks six numbers from 1 to 30 (Sorry I don't have the code at the moment).
My code runs fine, but I keep getting duplicates in the textbox. (I'll update as soon I have the code.)
I'd like to create a standard AutocompleteTextBox that works with a timer, such that there is only one BackgroundWorker working on searching - if the user entered a few more keystrokes, but the old search is still running - that search shall be canceled gracefuly (via CancelAsync), and as soon as its canceled the new search will begin.

I have run into a situation where my application requires data from an ancillary source that cannot be altered/changed, which of course means dealing with poor database architecture and implementation!

Perhaps I should be handling this when attempting to set the controls? Not sure, but here is the current way this is done:
