i want to create a GUI which content a button and when the button is clicked, a signal B'0000 0001' send out through USB port.
my pc already can detect my hardware through USB port.
So, i just want to know how visual basic 2008 setup USB port function.
I am in process of writing a setup program that will reside in a USB stick.After inserting the Stick the VB2008E program starts (dont know how) and guides the technician to do certain tasks. As a part of this She/He needs to run a Setup.exe that resides in the same USB stick.
1- How do I define the drive letter of this USB stick.
2- How do I run the x:Setup.exe program without exiting the VB2008? The install process should begin after click of a button.
3- Would Autorun work on USB drives to run the program automaticaly?
4- How do I compile to make a single EXE file at the end?
I am working to make a function that will update the back color of a text box based on multiple variables values. I can write the code to do the calculation, but I am not sure how to make the function realize which text box to update (as I will have about 30 different boxes). Below is the code that I have for each box so far, but I will have quite a few more, and would rather use a function to reduce the amount of code, and also make it cleaner as well.
If sngPreviousPrimaryPropertyTotal >= sngPrimaryPropertyTotalCost Then
txtPreviousPrimaryPropertyTotal.BackColor = ColorProgramLightGreen
Else
txtPreviousPrimaryPropertyTotal.BackColor = ColorProgramLightRed
End If
[Code] .....
Or is there a way that I can tell the function that it's updating the text box that call the function in the first place? Say if txtBox1 has updated text and calls the function, then the function 'knows' to update txtBox1, but will update txtBox2 when it's called by txtBox2.
I have a disk created with Inno Setup 5 with a Visual Basic .Net project on it. It installs fine on my computer. I want to give this disk to a client for him to install on his computer. My understanding is that Visual Studio .Net Framework 3.5 or higher must be installed on his computer. Is this correct? How can I tell if Visual Studio .Net Framework 3.5 or higher is installed on his computer?

Is there a simple sleep function in Visual Basic that doens't involve thread.
Something similiar like there exists in: C: sleep(1);

I am trying to transfer a very complicated Matlab function into visual basic. It takes a matrix input and gives 4 outputs.
From my own research I found something called Matlab CODER, which can transfer matlab code into C/C++ code, however, this function is too complex for that. So I guess now my question is, it is possible to call my matlab function somehow within VB and store the outputs for use within my VB program?
The matlab function looks something like this:
function [f,x,s,c,l] = mytest(Y,varargin)
%Code here...
end % function
I'm working on a small freeware application in Visual Studio 2008 Standard that will match geographic data to a geographic position. For this I need some mathemathical functions and one of them is how to detect if a point is inside a polygon. There's a great solution for this from the Microsoft team at: [URL]
but it is in a different programming language that I do not know anything about. How can I use these functions in my program? I'm afraid that if I try to rewrite them in Visual Basic I'll make mistakes that I can't detect. To be complete, I'm not using screen graphics so I really need a mathemathical solution.
I'm doing a baseball program for a class project. And I almost have it complete, but it's giving me a syntax error. I can't figure out what i'm doing wrong. I'm using two functions to return a value for different type of baseball tickets to the button that calculates them. Here are the instructions 1.)User selects whether to purchase season tickets or single-game tickets 2.) User enters the number of tickets needed and the type of seats based on whether they selected season single-game tickets.3.) User clicks the Compute Ticket Cost Button to display final cost4.) User clicks the Clear Form button to clear the responseI just can't figure out what I did wrong. I know it's something stupid that i'm doing.the errors are happening inside the btnCompute sub routine. with syntax erros on SingleGameCost() and SeasonalCost() line 114 and 118

In a while loop, I am writing a progressively increasing integer value (between 0 and 100) to the Value attribute of a ProgressBar control, when it disappears from the window in which it resides. I have verified at the time that it disappears that the Min is 0, Max is 100, and Value is a valid integer in range.

I am very new to Visual Studio Application Development. I'm mostly a DB guy. I used Visual Studio as a Report Designer, not much of an .Net guy though I can understand it.

My step-by-step guide says choose Visual Basic, Windows Forms Application. But I can't see it as an option.
