I am new to arraylist. I have used standard 2 dimension or single dimension arrays which is there is .net & legacy VB.What I want is removing & searching in arrays to be easy ? VB.net does provide something called arraylist whereby we can remove items easily like X.removeat (index) or x.remove (search) etc.[code]Now I have a array person. To add i do redim person(10) or using preserve if I need to dynamically add etc. To remove is a pain as I need to copy contents and remove manually.Anyways in .net you have option called ArrayList.How can I use this to make life easier? If I want an arraywhereby I can do person.removeat (2) or person.add person.name="XYZ" & so on.Just wanna ease up on searching & removing.
View 6 RepliesIs it possible to determine how much RAM a process is using?Let me rephrase that, is it possible in VB.net to do this, and if so, how can I do this?
View 2 RepliesI am currently running through a loop with 20 threads. These loops contain a series of 3 HTTPWebRequests (relatively CPU intensive). At the beginning, CPU usage never spiked above 10%. After about 7 hours of run time, CPU is spiking up to over 40%. I believe that this will eventually lead to the program crashing (it has before in less time, I modified some things and it seems to be running longer). What kind of intense CPU spikes are associated with threading? More importantly, how can the duration of runtime affect CPU usage by so much?

View 9 RepliesIm wondering if there is some way of monitoring individual processes (read: not mine) cpu usage and ending (asking politely then killing it off) the offending process. I dont know about you, but i've been in multiple instances where i've been unable to get to taskmanager to "choose" process to be killed. For multiple reasons (Either taskmanager has been visible, but a game window is still showing (alt+tab not working), leading to a guess game of clicking processes or cpu usage has been so high that one mouseclick takes 30 sec.)

Im trying to monitor the battery of notebooks to diagnose whether there charging/discharging correctly or not for my work. I can get the basic info using SystemInformation.PowerStatus but i want to be able to see the slope or decline of the charging via a graph. Is this possible? i was playing with the system monitor control and thats the kind of output im trying to get. A simple line graph would be perfect....passmarks battery test is a example of what im going for
View 2 RepliesHow do I get the cpu usage percentage to display in the label on a form?
View 4 RepliesThe following code works perfectly to allow moving a control on a form at run-time. However, when AutoScroll is set to True on Form1, and you drag Button1 past the right and/or bottom bounds of the form, it goes haywire. I really need someway to smoothing control the autoscroll so that as you scroll the control off the form, the scrollbars smoothly appear.

I'm writing some VB2008 code to control four 7-seg LEDs I bought from Velleman. They came with some example code in VB 5.0, and with instructions telling me to input 5 bytes at a time in the format Chr$() & Chr$() & etc. for the rest of the 5 bytes. When I try to do this using VB2008, it rejects the $ sign, so I've tried it using the Chr() format, which VB2008 allows. However, it doesn't work. Is Chr() the new version of Chr$() or are they different entities? In sending data to the LEDs, I'm using LiveComPort.WriteLine() as my command. (My serial port is called LiveComPort) I also tried it with LiveComPort.Write() asthe command. I know that my serial port and the LEDs are working, because they respond to the demo program provided by Velleman.

2) How to make the RTB's Back Color to transparent??? Cause it is not supported. Or is it I use the wrong control???

View 2 Repliesi am a beginner in vb.net programming...started a project in it.Below is the breif project description.The application is to ensure the integrity of the files.Following are the majors things that i have to implement
1. To browse the files from the disk on runtime.initially i am just taking the database files so it's basically to connect with the MS access db files.
2.To apply the different hash and encryption algos on the file.
3.To store the results on the hard disk back.
4. To calulate the performance of each algo using some performance matrix.(TIME,MEMORY USAGE etc)
Now i am having problem in two things.First in runtime connectivity with MS access batabase..and secondly and the main problem is that i could'nt find any appropriate builtin function to calulate the processing TIME and the MEMORY usage.
instead of using if control.invoke required in a procedure can I just call the procedure with begininvoke?I have, possibly, the following:
Private Sub UpDateTimer_Elapsed(sender As Object, e As System.Timers.ElapsedEventArgs) Handles UpDateTimer.Elapsed
UpdateTime()
If MicActive Then
PTTCancelTime += 1
