Anyone know how we can connect a USB cable to one of the ports on the computer and send keys to it and have that acted like it was a keyboard if the cable was connected to another computer? I'm sure the USB jump drive for example is like a mini-computer, so how do we do the same thing but with a computer? Is there any code in VB, .NET for this?

How to emulate a mouse click with directinput?
like ive been searching for this for hours and can't find anything decent for VB 2008
Visual Basic 6 had the Text Box Array that worked great.It no longer exists(in the same form) in either Visual Basic 20085 or 2010.I know that there are work-arounds that emulate the Text Box array but these are certainly not as easy to use as the version 6 Text Box Array.
In Visual Basic 2010 there is a tool box item that can be added, called Text Box Array. However, this does not place a Text Box on the form and I can't find any explanation of how to use it.what adding this to a form accomplishes and how to use it?

View 16 RepliesI am trying to emulate the Wordpress post editor. Basically Bold, Italics, hyper links, bullet points, and numbering. Is there an application I can incorporate into my project and if so how would I do it.
If not, how can I reference text that the user has selected in a RichTextBox. Say they have the first 10 characters highlighted and the bold button is clicked, I would wrap it with <strong></strong>.Also, in a RichTextBox aside from an html editor, how can I justify the text within the box?

-Stopwatch Class, still lags (little but still).

what I did was, I coded a HTTP web request "Browser". It's not a real browser but it's emulating a browser. It works fine, I'm using it to perform some searches without the clicking sound or audio from the pages (stupid ads).
Then thing is, it returns back the page's source code. There is a tag called "Block1". Now Since it's a string I can't just use str.document.getelementbyid("Block1").getattribute("value")but if the webbrowser can "emulate" then source code sent back from the HTTPBrowser then I can use it.
I have a serious dilemma! I have a com port COM3 and i USB device attached to it ! now when i use Hyper terminal and i can read and write to it using AT commands. for example when i type in "ATI" in hyper terminal it will return me a bunch of data how can i so the same using a VB program ? is there a way to emulate the functionality of Hyperterminal?

View 10 RepliesI have a problem with a purchased UI control, and to do a quick and dirty fix (no time to build/order a new control), I need to emulate a click at the right side, say 10 pixels into the control, from the right side of the control. Is that possible in vb.net? We can't do this functionality programmatically, due to a bad API design. And now time is running low.
Which method do I use to get the coordinate to perform the click at, and what code do I use to do the actual click? The code should move mousepointer to the location, do a right click and then return to where it was, hopefully without the user ever noticing anyting.
if there was a way to emulate the application.settings file's ability to do something like the following:
If I add an item to the settings file editor say Variable1 with a a value of "foo"
I can then go to my.settings.default. (and at this point) Variable1 is item that is an option after I type the '.'
Is there a way to do this for a collection? To where I have
Collection1. (and when I press '.' the name of an item would show up?)
I'm trying to automate using a remote ASP.NET website using the .NET WebBrowser control to simulate user input. I'm trying to call InvokeMember("click") on an image button on the remote site but it doesn't appear to be working and I suspect it is because the X,Y click coordinates that are submitted are both 0,0 (rather than representing real click coordinates). Is there any way I can programmatically set the submitted x,y coordinates to emulate a real click? (BTW I know I'm selecting the correct HTML element on the page so I've exhausted all other possible reasons why this is not working other than the x,y coords!)
