No Output In Asynchronous Program - Retrieve Output After The Events Are Invoked?
Mar 1, 2012
What I am trying to do: There are three powershell scripts with different time delays as shown below.I am trying to run them asynchronously in .NET and I followed this article to implement Asyncrhonous programming. Where I am stuck:The I am not able to retrieve output after the events are invoked.The scripts are being called but then the program ends and it shows "Press any key to continue" in console windows.I don't what I am missing here.
Info: JobRequest is a class that I use to pass around information keep track of jobs.
Sub Main()
OurAsyncFunctionCalling("psDelayScript2.ps1", "-arg1 4 -arg2 5", 1)

I'm just going to throw all my code in here in case there's something wrong with a piece of the code not in the "SelectName()" sub.
Module Module1
Dim selectednames As String = ""
Dim index As Short = 0
Dim inarray As Boolean = False
[code]....
Here's an image of what it does (I suppose you can see what went wrong)13 inputs, 3 outputs expected, only 1 output given.As from what I've figured out so far, it's doing the correct amount of loops etc. It's just as soon as it starts generating the "winner" for the 2nd game key it doesn't get a string value from namesarray.Also, why is
For x = 0 To totalnames - 1
Debug.Print("namesarray(" & x & ") = " & namesarray(x))
Next
not giving me a debug output?

I am suppose to be creating a mortgage amortization program that calculates the monthly payment and the amortization table for a mortgage based on user input of the mortgage amount, the interest rate and the length of the loan. I have worked on the program all week and finally got the program to compile; however, the interface does not give me any output. I already posted the assignment yesterday and am getting a C in the class but each week the program builds on the last week? Attached is the complet VB 2005 project file.

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 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

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'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 have 50 checkboxes that I need to write onto an aspx page. Each checkbox comes with 3 textboxes.[code]...
Now this shall go for all 50 states, depending on which states the person wishes to donate. In each state's row shall be a checkbox. So initially the page shall have value 0.00 in donation and new donation checkboxes, but all 50 states shall be visible. When the person puts a value of donation in certain state, that state shall get "checked" value and the donation, after submitting. On reloading, the value shall be populated automatically and checkbox checked automatically.
How do I make these 50 checkboxes in VB.NET?

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.

I 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.
