So I got this program to generate me some data and I want to show that data to a label.
If I don't do a display I can generate about 20,000 data per second, but if I do, I get about ~9,000 data per second.
PS. Since the generating logic in is a thread, I have a function that does the displaying to the label.
I have a loop in my program that iterates at the start about 20,000 - 25,000 times per second. By the end of the loop, the iteration is down to about 6000 per second. [Code] The Alphabetize function merely returns the string with it's Chars in abc order. Can you see any bottlenecks or any reasons for the slowdown?
View 13 RepliesI'm trying to animate a game piece by using a picture box where the x,y location is changed as the image changes (cycles through a walk animation sequence). This all works fine, however it's too damn quick. I've tried slowing it down using a simple:
for z=1 to 1000000: next
While this works-ish there must be an easier way to slow down code....is there? On a related matter: Why does picturebox animation look so crap compared to combining images in the paint screen section? My picturebox seems to flicker every few frames.
I am working on a program where a user either enters "small" or "large" and then the number of toppings. Once the user has done that my program outputs the total cost of a pizza based on user input.
My problem is no matter if I enter LARGE or SMALL into the textbox for size of pizza the output displays "A small pizza with 2 toppings cost: $x.xx"
It also displays the price of the pizza as a small one. So somewhere along the lines it changes everything to be small.
this problem only started occurring after I made this procedure.
Procedure that I believe is causing problem
Function IisUserInputValidSizeOfPizza(ByRef mytextbox As TextBox, _
ByRef errorMessage As String) As Boolean

I have 12 Boolean values in an array. Each of these values represent a CheckBox in my application. I want my program to output a string, based on each value not selected. Each of these values will have a predetermined string that is different from the CheckBox's caption and will be joined to create a final string. I want to generate all the possible combinations for when there are 1, 2, 3, 4 and so on up to 12 of these options at once. I can better explain my problem through the repetitiveness of the code below.

View 3 RepliesI work in an engineering design house and programming is not my actual profession. And I am relatively new to VB .net (previous i had worked in vb 6)
I am working on an in house application. I am coding a simple application in vb .net. This applications takes a few inputs from user and calculates a result. Now I want to implement a simple functionality that user should be able to save the input and results just like most of the windows programs can in a new file format. And user should be able to open the save file when desired.

View 1 RepliesIn the program I'm working on, there is a 'sign-in' form that pops up for the user to enter first name, last name, and DOB. What I want to do is STORE that information in a text file for FUTURE use by the program (i.e. displaying a list of all previous users of the program).I already know how to use streamwriter to write text to a file, but I would like for the text file to be stored within the program files and also for a new user's data to be appended to that file every time.
Do I simply add the text file to the project files? When I do that, its path is 'My Documents'. How will that affect the program when I publish it? I guess I just don't yet understand what happens when the program is finished and published. The code for the 'Submit' button on the sign-in form is pasted below. At the bottom, I've put a comment to indicate where I want to store the data to a file.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim TxtBox() As String = {TextBox1.Text, TextBox2.Text, TextBox3.Text}
For i As Integer = 0 To 2
If TxtBox(i) = Nothing Then

What is the output of the following program segment?
[code]...
Here is what I would like to do:
- Store string data from a 'sign in' form into a text file. This text file must be one that is saved even after the user exits the program. The text file must also be one that will stay with the program even after it is published (executable).
- Be able to write to/read from the file for purposes of displaying some or all of that data on a form.
I use an Application Setting to do this - of type 'Specialized String Collection'. I tried this, but for some reason I could not get it to work. It was a good idea, but I need to be able to SEE the data that has been saved, and with a setting it seems like that is not easily done. I've decided that I either need to use a simple text file or a 1-table database for this. I would prefer just a text file, but in either case, it needs to be part of the .exe when published.
I have added a text file to my project, but I am not sure if it will be "included" in the project when I publish it. The path of the file I've added is in 'My Documents', but in my code, I will have to specify the path in order to use Streamwriter. How will this affect the program when I publish it? I felt the need to make a new thread because on my last one we had been mainly talking about settings, and I've decided that isn't the best option for me.

I made a Visual Basic program that adds an interface to some Windows network diagnostic tools like Ping and Telnet. Currently the program opens a new DOS window and displays the results. For each system you test or each time you hit the button it opens a new window.
What I want it to do is redirect the output back to the program and display it using a List box or whichever is the best choice for displaying results. I have checked out posts that talk about capturing the text and redirecting it back to the program but I can never get those to work.
Is there an easy answer for this or does it entail a lot of additional coding? I am using Visual Studio 2008.
2.0 Framework.Our software does some measurement and then sends the output to our charting program. Right now it is taking 20-30 seconds for the results to print after our chart has sent the data to the printer since the printer is in sleep mode. What we are wanting to do is send a command to wake the printer at the end of our test, before it sends the results to the charting program, so the printer is (hopefully) done "waking up" by the time the chart program auto prints.
I have been looking around and haven't been able to find anything regarding this. The printer we are mainly using is a Brother HL 5250DN. I have contacted Brother but I have yet to hear anything back from them.

I'm trying to create a program that produces random sentences as output. With five arrays of strings, one each for nouns, adjectives, verbs, prepositions, and articles. Each array should hold several words for that part of speech. It's supposed to generate sentences by randomly choosing eight words (randomly generating eight array indices) from these arrays, always constructing sentences by using the parts of speech in the following order: article, adjective, noun, verb, preposition, article, adjective, noun.Also, theh code should be properly modularized so that the code to generate each part of speech is not repeated.

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.
