Create/read/write To A Visual Studios 2010 Pro Capable/provided Db?
Mar 31, 2012
still working on my game, but a college classmate said that I need to use databases instead of text files...so I'm wanting to know, what databases does visual studios 2010 provide for you to use...what code line should I use to create/write to/read from a databasew, and how do/should I create a database table/refer to it??
I would love to provide code, but I'm both using my cell, and don't have access to my computer right now due to it not being accessale due to not having the ability to have it hooked up right now...got new floors and don't have it plugged in yet/set up again...

To send serial data from Arduino Mega 2560 to a VB.Net PGM, then the VB.NET pgm will read data then send to via FSUIPC (an Addin DLL) to ms flight simm 2004.OK that said here is the question: how can I write or phrase or construct the proper syntex needed to 1-limit the data sent,or in reading the data-limit the data read?I have enclosed the VB.NET code and the Arduino code. Please take a look. I am very new to both,but I try hard. all the code works but I get strange all most random data in VB. The FSUIPC end works OK, I can send to and receive from Ok.It's the VB pgm that gets the data wrong some of the time. say 8 out of 10 it is OK then button x will also turn on or off another check box then do what was aked. It seems that I am not clearing the receive buffer so I get a last chr sent before.I have tryed readline, readexisting,readbyte but I don't know how to phrase or construct any but the readline. I have tryed to flush the buffer in both codes but, well I am stuck. [code]

I'm trying to make a rs232 serial data logging program, that accepts a 12 bit hex RFID tagID from an RFID module. My end objective is to save this RFID tagID into a database and assigned to a person for a personnel management system.I had to use button3 to add the value of the variable 'msg' into textbox1 because I was getting the following error "Cross-thread operation not valid: Control 'TextBox1' accessed from a thread other than the thread it was created on". It is a temporary workaround.When I do press button3, I get the incomplete hex number, instead of "4C00A2C82A0C", I get "A2C82A0C", and sometimes I get random digits like 1,A,C etc etc.
Public Sub OpenPort()
Try
If SerialPort1.IsOpen Then
SerialPort1.Close()

when the user clicks on the add button another form launches, which enables the user to add student info such as name, address, course, start date and end date, this information is then written to class when the ok button on that form is clicked, and then displays the data on the initial form in data grid. the user can add multiple entries and they are all displayed on the intial form and a the data grid is populatedwhen any of the rows in the displayed grid is selected, and the update button is clicked then the same form launches as the previous one and but this time its in the update mode and pre populates the form with the inital values.

I've been browsing and I noticed that there are addons you can install for your visual studios environment. What would some of these be? What are some addons you guys use that would be beneficial to a student? I have heard that certain addons block out default components, which I would like to avoid.

I can't seem to find the shape tool in the toolbox? When I used VB6 there was one, so why isn't there one now? I just want to set up rows of circles so I can change the color from inside instead of using images and saying
Code:
YellowCircle.Visible = False
BlueCircle.Visible = True
Instead of doing that I want to do
Code:
Circle.BackColor = Blue
How do I draw a shape in VB.NET? Not during the program, before.

How do I create commands that allow a group of adjustable voltages to be provided outside the computer, via the usb, serial or paralell ports, etc to control devices connected to the computer?
As a former electronic technician and developer, I have several useful projects I would like to develop.For example, I just received a celestron digital microcope and I am interested in developing a speciman stage the microscope can be placed in which provides a from 4 to 8 adjustable led's located above the speciman and more below the speciman so the lighting on the specimen can be adjusted in a variety of ways so hidden features of the specimen will be revealed when viewed from the microscope.
how to send the commandsf rom the computer to outside devies for further processing is my primary concern into a port to accept these voltage commands since I am behind on current technical advances in the electronic field.

I have an excel database with one column and thousands of rows of "number" data. I need to import the data into my form read the first entry, run an algorithm then move the result to the second column then move to the second entry and so on. I am having issues with where to begin. I am able to convert the excel database to a text file if it makes it easier.The algorithm that needs to be ran consists of reading each character one at a time and is as follows:ENTRY example: 12358458754The characters 1,3,8,5,7,4 need to be summed then multiplied by 3. These are all the characters starting with the first one and skipping every other one. I will call them "odds" (not referring to numeric value)The characters that are skipped, I will call them "evens", need to be summed together then added to the result of "odds".

I've been scouring Google looking for a solution to my problem, but I can't seem to find anything so thought you guys might know a way of solving my problem.Im writing a little program which needs to change a few different memory address variables of a specific process.Does anyone know how first of all I can detect if the specific process is running on the user's machine, and then how I would read the value of the memory addresses, and write to them also.

I am trying to edit the process memory of a game (Age Of Empires II: The Conquerers). I can edit the memory manually on TSearch and it works just fine. I want to this with VB.NET but have had no luck. Note: I am not doing this to cheat, I am just using this as a learning experience for changing process memory.

I have recently decided to give .net another chance, but i have a few questions about it before i get really into it. RE: Files, I use random access files to store data as opposed to databases (namely i don't see the need for a database for storing so little information(records <200 max) knowing that it is an older system and less "cool" i don't care...) Will vs2010 express read, write to random access files? Would it be done kind of like vb6 (which is my current vb version)? I will be needing to print the text of rich text boxes, is vs2010 express capable of doing this?

I got an Arduino hooked up to the PC and would like to read the serial port of it. I read the serial port in Visual Basic with com.Readline, but it won't read everything. It looses around 2-3 lines that were sent over the serial port to the Visual Basic code. They get "lost".
