View 1 RepliesProgram Run Out Of Memory - Draw Segment Of The Spline To The Bitmap
May 31, 2009I am building an app that builds a bunch of cardinal splines by storing their PointF structures in arrays. As the program runs, new points are added to the arrays, and the graphics are drawn to a bitmap. I can let it run for ages and the splines just keep growing like they should with no problems. The amount of points in each spline can grow into the thousands. To speed up execution as time progresses, I don't completely redraw the splines after each pass, I simply draw the last segment of the spline to the bitmap, having let the bitmap 'record' the earlier part of the splines.
But if I pan across the scene or zoom in/out of it, then I DO have to completely redraw the splines, since the size and resolution of the display is limited to its dimensions. Panning works, no problem. But if I zoom in and out of the bitmap with the mouse wheel, after about 14 wheel clicks, I get an "Out of Memory" error. BUT...I have it set up so that whenever the mouse wheel turns, the graphics and the bitmap are disposed so that new ones can be built for the new zoom setting. So why would the program run out of memory when as far as I can tell, I am disposing of all my unused, unmanaged resources on a regular basis?
No Output In Asynchronous Program - Retrieve Output After The Events Are Invoked?
Mar 1, 2012What 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.

Trying To Understand Code Segment (XML)
Nov 21, 2009I'm just getting back into VB and was never a pro. The last environment I was in, briefly, was VB6 but spent a good amount of time coding in early VB's back to QB.I'm trying to read RSS feeds and found a nice demo reader but now I want to understand the code I'm seeing:[code]
1. Why does the demo create a new XML to read through an existing XML or is this all in memory as I can't find an actually file? Is this even needed as what I want to do is read the RSS feed, grab some info from it (Source, Title of each story, Date stamp, author and the story text) and then process that in various ways (not actually view it... I want to e-mail specific stories directly to me that fit my search criteria). Or is this just opening the XML out on the web? That would explain why sending it "test" gives me an error saying it can't find "test" in the bin folder as without an HTTP address it goes local.
2. doc.load... what check can I perform here to be certain that the data entered by the user is actually a valid feed? It should, for example, have a first line header that is reliable but is that the best method?
3. Where or how are the elements stored that I can then refer back to pull the data out I want?
4. I don't understand how this part works: navigator.Select("/rss/channel/item/title") Can someone shed some lite on the 4 pieces at the end?
5. I'm assuming the clean-up isn't really needed for e-mail but I didn't remove it as it doesn't seem to harm anything.

Redirect Output To Window Within Program?
Dec 21, 2011I 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.
Sends The Output To Our Charting Program?
Jun 4, 20092.0 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.

View 2 RepliesVS 2010 Program Keeps On Displaying The Same Output
Dec 2, 2010I 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, _

Create A Program That Produces Random Sentences As Output?
Nov 14, 2010I'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.

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.
