View 2 RepliesI've run into another road block while programming my game. The problem is that when a player types North in room "Crash Site" They get the description of traveling to the next room "In Trail" as well as the description of traveling to the next room after that, "Deeper In Trail" before having to type north again. I've looked over the code several times, but can't find the problem....the conditions seem to be fine, but I'm guessing that's where the problem is..
Code:
ElseIf LCase$(txtInput.Text) = "go north" And Room = "Crash Site" Then
Room = "In Trail"

View 1 RepliesI am having an issue where I need to implement a type of thread scheduling... I'm looking to implement a list of tasks, each with a set time that they need to execute, and after the time is up they will execute the respective code that goes with that task. I would use a timer based solution, however, I don't think that it would be very efficient. There will be a very large list of tasks, some of which need to be executed within seconds of being placed in the list.

View 5 Repliesat - arrival time
bt - burst time
I - idle
for example the user input 3 process
process 1 - at = 5
bt - 5
process 2 - at - 2
[code].....
this is the logic : smallest time + burst time = sum1 if the next arrival time is less than the sum1 then add the next burst time but if the next arrival time is greater than the sum1 then subtract the sum1 to the arrival time so you will get the difference1. after that the difference1 must be added to the sum1 then add the burst time. that is the cycle.

What is the best way to schedule task on VB.Net application? I have searched this forum and google but I still need some more comments.There are two ways that I've found so far:
Command Prompt By using AT or SCHTASKS command. My Windows 7 seems to recogonise both Command. May I know is there any significant different between this two command?
Timer By using Timer function, but I'm not sure whether is this a good method as it might slow down my program by constantly checking. May I know by using the above method, can I retrieve the scheduled task and display back in my program with ease?

View 3 RepliesApologies for the long post, but I would be very greatful for any advice given. I have developed a visual basic application to communicate with a device through a COM port. This application works fine. The device connected to the COM port sends information relating to the status of the device, this information is read in using VB and inturn written to an SQL database. Using the visual basic application the user can also send commands through the COM port to the device. The application scans the users computer and detects all available COM prots, these are presented to the user and they can select which one to connect to. The COM port is held open for the entire period that the program is in use (this is to allow for the incomming information to be read)

I have a program that checks for the date and minute part of my job object. If these match then it triggers a particular job.
If jb.ScheduledStartTime.Value.ToString("MM/dd/yyyy mm") =
Now().ToString("MM/dd/yyyy mm") Then
'Do some work here.
End If
Issue:If I schedule different jobs during the day at different time interval then they just work fine. I mean they are triggered and in the above code they enter the loop when it matches the current format.
However, it doesn't work when the date changes at 12:00. Even though I have scheduled start time set to trigger at 9:00 AM in the morning it enters the loop exactly at 12:00 AM which is invalidating my logic leaving me confused.
I have 5 separate class libraries where each one of thses are consuming separate web services (the web services connects to a server, runs stored procedures and return data tables to the .dll).
My task is to sequentually run these 5 jobs unattended through a job scheduler. I am not really sure how to do this and what my options are.I was planning on creating a driver (a console application) that would call each .dll. If this is a acceptable way then I am not sure how to reference and call each .dll, could I use import, add a reference to the .dlls and instantiate a new class, make a setup project with dependancies etc.
I need references to how to schedule emails to notifiy users on a specific date in the month (each month).All the references I stumbled upon were in C#.I'm not that advanced to convert them properly to VB dot net.
View 1 RepliesI am using Umbraco (a .NET CMS), and it has a reference to a specific version of a DLL (see 1 Umbraco Reference below). This is fine until I try to hook into the .NET MailChimp API which references a different vesion of the same DLL (see 2 PerceptiveMCAPI below).I can think of a couple of options for resolving this
a. Get either the Umbraco or PerceptiveMCAPI source and reference the same version of the DLL, really do not want to do this for compatibility reasons
b. Dump the 2 DLLs in the GAC, I want to avoid this as I see deployment issues arising if someone forgets (I know we should have an automated deployment but time is restricted)
I remember that there is a third option to specify what version of the DLL to use in the configuration. Is this possible and what is the code for it?

I've got a bound Combobox in a database for a lookup but when i set it up and change the data in the combo the program won't let me go and further. There is a data conflict but i don't know where. The problem is here in the combo setup:
Display member : ProductName (nvarChr(20)
Value Member : ProductID (int)
Selected Member: SelectedLookup (int)
This doesn't work. Everything is displayed in the dropdown by name but when i select a item. I can't go any further. If i change the Display member: to 'ProductID' the program works fine. but displays the ProductID where users won't understand. It's like it is trying to store the 'displayed member' Product Name instead in the Value Member 'ProductID'. if i use a list box instead the program works correctly.
I've been encountering this problem. When I add a listbox at my game, all my keypress events and codes doesn't work. But when I remove it, it will work again. I don't know what's the problem. I need the listbox to add strings on it for my game.

how to implement scheduling tasks requirement in my application..
I have an application that I need to automate where at a certain time each day, say 6pm, it will run a certain method(which is to check a database for key terms and then access the api to search for these terms). But there is also another process which is running all the time accessing the stream api so when the search is complete, it interrupts the stream and hands over the new terms.
Now I thought of adding the .exe file to windows task scheduler but not sure if that would work. The stream method run indefinitely and at 6pm each day another process needs to run. I thought of using the system.threading.task TaskFactory but when I include it, it shows taskfactory as undefined. ( I do have .net framework 4.0)If it launches using the task scheduler as 6pm with my code logic as follows:

I have a question for the well versed among you. I have done some research, but didn't seem to find the exact answer I was looking for. So without further adieu.Given an event which needs to occur at a very specific time, whats the best and most predictable way or making that happen.
A: Use a worker thread, and threading.thread.sleep(TIME).
or B: Use System.Timers.Timer or System.Threading.Timer to execute in (TIME).
NOTE- I am fully aware that any of these will work. My question is in regards to priority of execution. How will a timer, which I can't figure out how to set a priority on, compare to a thread with a priority of Highest or even Real Time. Microseconds DO count in this instance.
create a chat room? My current hosting is a linux server with mysql. I want to make a client that can connect to the database.(already done) and if the user exists, to open a chat form. I want this to be multithreaded, that way I can have up to 500 people chatting with each other at the same time, from different locations. (realistically will usually be around 50)I have found some winsock type examples, but I dont understand how I can adapt that to work with a linux server... Can anyone help give me examples?

View 5 RepliesI have a datagridview in which the user can add new rows. The datasource is a datatable who has a unique-constraint for the column "Position". Thus, if the user enters a position already existing, an exception is thrown. To avoid the ugly standard error message, I simply handle the dataerror-event and set e.cancel = true. This works. But if the user presses escape, the row_validated-event is triggered. I use this event to format the rows containing new data by changing the font color to red. Here another exception is thrown (SystemOutOfRange-Exception) telling me that the index xxx has no value. How can I achieve row-formatting for new/modified entries without getting this error?
