Nov 18, 2011I am working on a simple vb project to read data from a PC serial port and write that data to a file.The data is ascii sent in Hex format. I used MySerialPort.ReadChar() to read data and MyStreamWriter.Write(MySerialPort.ReadChar()) to write it to a file.
I copied my code below, sorry about the format.The trouble is: MySerialPort.ReadChar() acts the same as MySerialPort.ReadByte() , both takes the Hex data input and returns data in decimal format.I tried to use Convert.ToChar(MySerialPort.ReadChar()) to covert decimal to char, but it's too slow.I tried decimal.ToChar(MySerialPort.ReadChar()), but VB doesn't recognize decimal.ToChar, even after I installed .NET4.
Did I do something wrong? how to make MySerialPort.ReadChar() to read Hex data and return char?

Dec 21, 2009I have an issue with a third-party COM+ DLL meant to be used from VB6, where it has a function to set a Callback for a hardware event.

.net - Function That Always Returns The Next Integer In A Sequence
Feb 10, 2012I need top create a function that gets the next integer in the sequence of 1 to 60. Each time the function is called, I need it to increment from what the last value was and return the next number as the result. It also cannot return the same integer in 2 consecutive calls. When the count gets to 60, the sequence needs to reset back to 1. I would like to function to have no parameters.
I have created a function that does this using the cache to store the last value that was returned, but I am worried that with concurrent calls to the function that it might not work as I expect and 2 calls could get the same integer.
Is cache blocking the correct method to use in this instance or is there something other method I am not thinking about?
Also, stuck using .Net 3.5 and this is a web application.
I just wrote this function based on using SyncLock. Any obvious problems with it that I don't see? I am using the Cache to save the last value that was returned.

Casting A Boolean To An Integer Returns -1 For True?
Sep 1, 2010I am working with some VB.Net code that seems to be casting a boolean value to an integer using CInt(myBoolean). The odd thing that is happening is that it returns -1 if the value is true. For example:
CInt(True) // returns -1
CInt(False) // returns 0
Is this common in other languages? I thought that a boolean would be 1 if true and 0 if false. Also, is there a way to make VB assign 1 to true instead of assigning -1?

Mar 16, 2011I have a project to make a "3x3 magic square" and I'm not quite sure how to begin. A magic square is a 3x3 table of 9 values where the sum of the values along any row, column, or either diagonal all add up to the same value.I have to use listboxes to create a form displaying a table of 3 rows and 3 columns whose elements can be individually updated. The solution should have the following features:
- a procedure that initializes a Listbox to hold the value "?", representing the value "undefined", in each of its locations. The number of locations should be provided as a n additional parameter.
- a procedure that will update the contents of a listbox by replacing the currently highlighted entry with a value provided as a second argument. The program should at most have at most one entry among the listboxes highlighted.
I am trying to use a Function that returns an integer value: -1 if not all the elements on the table contain values, 0 if the rows/columns/diagonals don't sum up to the same value, or the sum common to all the rows columns, and diagonals is returned if everything is alright.The user will enter a 3x3 set of numbers. The program will monitor the status of the table as values are entered and displays the status in a textbox that describes if a magic square currently exists. If not all the entries have been made to the table, then the textbox should display a message indicating so.
Array Of Integers Comparing Integers?
Feb 2, 2012Basically I have and array of integers that vary in size. I need to compare each number to each other number and display which number is repeated. For example:
Dim ints() As Integer = {1,2,2,5,4,6}
The number that shows up more than once is 2.
How can I run through the array and compare each integer with the numbers in the array. I tried a for loop but it didn't return the value I was looking for.
Calling Function A In Funtion A?
Jul 5, 2009I have this simple function (below) that randomizes number between 1 to 10. This function works well, except when Random() returns 5, which means intLot=5, randomizeAgain = true, and then the same function RandomizeNo will be called to randomize again. (refer the code below)
Even the new value of intLot equals other than 5 next time, say 4, the funtion returns 0.
I have no idea why. Function RandomizeNo(ByVal totalLot As Integer) As Integer

VS 2008 For Loop With Integers?
Jul 30, 2009I currently have a grid of 30 buttons, (6 x 5). So I named them btn1_1 - btn6_5
When the board loads up (this is for a jeopardy game) I have this
code
For counter = 0 To 5
Btn1_#.text = counter * 200
Next
Is there ANY possible way to do that (replace # with the number of the counter.) I doubt there is, but it never hurts to ask!
As a side note, where is a good place to post the jeopardy game that I am making in these forums, i tried both the code bank and gaming forums but they are dreadfully inactive.... since it is in VB.NET, i was wondering if i could post it here.
It is still in the making, but I would really like some feedback as i worked hard on it and got stuck for 6 hours on the save/load feature that was getting messed up cuz of a difference from A and a lol.
Button On Program Doesnt Seem To Funtion On Another PC?

VS 2008 - Anyway To Time How Long It Takes A Message Box To Pop Up?
Sep 9, 2009I'm trying to time how long an operation takes in Visual Basic (VS 2008) but its not working. the code I have is as follows:
[code]...
this is in an OnClick event, so what happens is that the user can click a menu item, and it goes and sends any changes it has to a database, and pulls down any new changes to a local data cache. This operation takes time, depending on how many changes are on the server and how many are cached locally. I've thought about making this a background task, so it doesn't draw away from the main app while it's running, but before doing that, I'd like to get an idea how long the operation takes. Since I can't exactly do a progress bar, I figured using the stopwatch would tell me how many ticks/milliseconds would occur between click, and when the "total synced" message comes up, but every time i run it and do an update the message always shows 0 ticks/ms. I don't think it's accounting for the delay, just from start to finish. Is there any way to make it so it detects a message popping up and times off that?
VS 2008 Seeing Long It Takes To Copy File

timeElapsed = 0

The issue is, timeElapsed always comes back as equaling 0, so fileCopySpeed always equals infinity. Also note that test.dat is a 100MB file. There's no way it's getting copied in under 1 millisecond!

Zoom / Magnify Funtion For Unknown Control?
May 26, 2011I have a Application that has a web control that loads a map from internet on a timer.what I need is to have a designated part of that blown up so I can see it better, think of it in this term, a map of the USA displayed and I want to draw a box around a state and display that in a seperate box and have it say.. 3x bigger.heres the original pic strait from the web now it displayes it just like it displayes it here, and I can draw a square around where I want it to zoom just so the user knows what area is zoomed, and this will be able to be turned off/on as it isnt really coded to do anything its just a visual aid and this pic below needs to be the result on the same form just out beside the webpage, I can have it load to a picbox, or another control that loads images Note that this was done with a photo program manually, I dont know how to code something like this.you Know Your Addicted To Computers When - Your main computer is a 7 terabyte, Core2Quad 3 Ghz +, with 4 or more gigs ram, over 200 programs installed, and you would rather sit with it programming than go to the movies!I've got 13 PC's in the House and 7 are in my bedroom and my main one exceeds this set of stats.
View 14 RepliesVS 2008 - Web Services Application Takes FOR EVER To Build / Run Using Windows 7
Jul 6, 2010I'm a relatively seasoned VB (COM) vet but this is my first VB.Net application and as is my luck a web services application feeding off a site that I can't publicly mention nor can I post any code that may expose the site.
So, here's the problem. I have written a simple form and have 2 buttons. 1 button simply asks the webservice for it's version. This works no problem. I was able to load the web reference using their supplied WSDL file for this "version" class. Now that I have that working I think "GREAT, that was straight forward. I have my credentials, urls, etc working, the rest of this should be just as straight forward." (See where I jinxed myself here?)
Anyway, I move onto the next WSDL and set of classes and get that reference added no problem. (Man that took a LONG time, like 20 minutes.) I then build my "Get my order data" code syntaxes on the prescribed exposed classes and run my project just to see what errors I get. The "run" process takes almost 45 minutes to an hour..... It's as if the app is getting the WSDL set all over again but doing it over and over..... I have no clue what's going on.
I've tried to disable all the Windows 7 "potential" issues, UAC, firewall, etc, but these changes don't help. Anti virus, spyware, etc all these are off and no difference. I'm running VS2008 as an Admin, right click "run as admin", and have complete control over this machine. Any ideas, suggestions, etc are VERY welcome and I am happy to expose as much of this application as I can providing I can stay with in the rules of the confidentiality contract.
