View 3 RepliesI have a standard scoring algorithm but I need to help on a piece of code to only execute the scoring algorithm at certain times.I want it to be triggered by dates, but the problem arises if the program is used after 2 (or more) dates have passed, the first date will not be added as the second date is the newest and therefore the one that triggers the scoring algorithm. - The scoring algorithm gets the scores for that week, which are stored in a text file.

View 1 RepliesI was recently assigned to do some research on how to approach a project. Right now we have an old program written in tcl. From this tcl program ( running on VMS client computer), we are able to run unix commands to execute processes on a unix server. This is done via tcpip. Now, we are thinking of making upgrades to this system . We are wondering if this kind of thing was possible with Visual Basic. Are we able to run a VB program on windows computer to run UNIX commands on a server? If so, what issues might be brought up. If anyone has even the briefest guideline or tip on this,
View 3 RepliesI am trying to create a piece of software that will help people develop there ears, so that they can learn songs by ear.For this, I am creating a piece of software that plas a musical note and you have to answer what the note is. the plan is, the sound plays, but incase you miss it, you can tell it to replay, and on the page, there is a text box, where you type in the musical note and then you click accept, and you get a new sound, and do the same. and I want it to just loop and randomly play sounds up untill the user clicks end and then I want a score sheet to come up with there answers and what the actual answer was and basicaly what there score was.
I will be ok making certain parts of the program, but there are a few concerns. the main concern is how to get these sounds to randomly play. and have the answers with it too.
I have a service that scans network folders using a parallel.for method. However recently I am finding if I stop the service then while windows says the service is stopped the process is still running in task manager. However it is at 0 cpu and the memory does not change. If I try and end the task (even a force in command prompt) it just says access denied and i have to reboot the server. What would be the best way to make sure everything terminates? I thought of adding a global Boolean that in the stop procedure it turns true and part of my parallel code will check for that and call s.stop.

View 2 RepliesI'm trying to, from a client-side piece, call off to a server-side piece. I need to do this synchronously. On my server-side code, though, I'm calling off to another piece of code, which I want to have a maximum of, say, 10 seconds to return a value. If I don't have a response within 10 seconds, I want to force my own server piece to set my result equal to 0, and return to the client.
Here's what I have on my server-side code so far:
Public Function GetWebResult(ByVal inputParameter As Object) As WebReturnObject Implements IWebInterface.GetWebResult
Dim result As New WebReturnObject
Dim webItem As WebItem = Nothing
[CODE]...
I realize this code is not functional. The problem is that I'm unsure how I would go about getting back into GetWebResult to set the appropriate return values before it is sent back to the client.
Currently I'm creating a task that runs a hardware i/o loop for the duration of my program.i.e. it's a task that's created at the program's start and runs a loop that is only broken at the programs termination. Each loop cycle communicates via ethernet to hardware.depending on time outs each cycle takes 30-300 msec)I've noticed that if the loop runs with out any break that the program really slows down... to counter act that I placed a thread.sleep(x) in the loop

My question maybe not be very clear, but I just want to know how this process is called or references needed to create something similar, so I can investigate on my own ( but if you have code is welcome.Basically I have 2 desktop programs ( A and B). For A, I do not have the source code, for B I do.What I need is to create some service/program that after a screen pops up from program A, automatically runs B. IN other words, capture the moment a specific screen is shown in A and execute B.
My real life scenario is that I have a very basic POS where I can't collect customer demographics ( zip code, etc), so I created a second application to capture that but my cashiers are always forgetting to run the program and I need to find a way to run it after a screen is shown ( let's say the "Change Due" in the POS, so they don't forget to run it.

View 3 RepliesI'm new to MVC2 and my question should be pretty basic. At least I thought so until I could'nt find any answer on the web, so here I am.
I have a parent object Pool that can have 0 to many children Question.
In my Details view of Pool, in addition to the Pool's property, I render his childs using RenderAction on the Question action List, so far, so good.
Inside my List view of Question (which is always rendered inside the Details view), I want a button to start the Create action of the Question object. My problem is, I don't know how to pass the Pool object, which is the model of my Details view, to the Create action so that I can link my Question to the right Pool.
Is there a way to access the "Master" Model inside the "included" view via RenderAction and if not, what's the best way to implement a work around.
