I need to make a program that executes other programs and makes then believe the time I want. For example, If my PC time is 6/4/2009 12:15am, I want the program I'm executing to think the time is 2/3/2009 6:00pm.
View 3 RepliesWith a Time value in my program. Basically, I am importing a travel Time from a database e.g. 3:45 so it takes 3 hrs and 45 minutes to get from a to b. I then want to double this - 3:45 * 2 = 7:30, and then want to multiply it by a cost e.g. travel is charged at 25 per hour. so it would be total travel time = 7:30. Travel cost = 25. Total Travel Cost = 7:30 * 25. In the access db, it is stored as a text field, and then imported in vb as a string.
View 1 RepliesI have a program that allows a user to select a program to run at a certain time for a specific amount of time all choosen by the user. Everything works with the exception of if my program has launched the other program, my program become non-responsive. Meaning I am not able to look at that window again. Not that one really needs too, because when time is up my program closes the program it opened, then closes itself. I just want to be able to see my program when the other program is running. how to do this and perhaps drop me some links, that would be wonderful. This is what I have coded, but like I stated there are no code errors.

I am currently using vb 2008 and want it so when a user registers it will unlock all the extra features and stay that way even after the user quits and restarts the program... I already have everything set exept for the save feature. I don;t know exactly what to do. I just want to save the settings of my program so that they are the same every time somebody uses the program. I heard that you need to go into Project , then properties and then settings... But I don't understand what to do there...

I have a program that after clicking start, starts looping. Most of the code is in the "start" button event, and the timer keeps calling it every second. Basically the program reads a line from the serial port, opens and reads a couple text files, opens and writes a couple text files, sends a string out the serial port, then repeats.
After about 24 hours of running, the computer and this program get very slow. Screen updates get really slow and clicking on buttons takes the program several seconds to respond. The actual loop itself slows too, I think, but not much. Restart the program and everything is happy again. What would be the best way to go about troubleshooting this? [Code]
I am aware that if you wish to run a program at a specific time, the best way is to add it to the windows task scheduler. I have a forms application that accepts as input a text file and some button selections before the actual main runs.
Can this kind of program be scheduled? I realize I would have to hard code the inputs but does .net have any features to access the task scheduler?

View 8 RepliesIs there a way to code, so that if your program freezes over a period of time (5sec), it just stops trying to do it, and goto something else.
"On ERROR" wont work, since its not a error. "Try" doesnt work ether.
Its because I'm am programming something that can login to a router thought telnet, and sometimes the telnet ActiveX doesn't read the buffer or the line proberly, so when the .GetLine() func is called, it freezes. And i want away to goto another point if it keeps freezing for more than 5secounds. The telnet ActiveX that, I am using is Dimac w3sock.
