I am looking to record information about the computers power consumption over time, is there any way I could do this using vb, I can get the current voltage from the processor but do not know the current therefore can not work out the wattage. I know of application which do have power consumption recorders but I would like to create my own.

Can I monitor the registry for changes similar to how sysinternals process monitor does it in VB? I have checked many different articles and C# samples but not come any closer to getting an answer, I would like to know if there an easier way (a VB sample perhaps)that you folks can share. Ultimately I'd like to be able monitor other things too like file system, processes etc but wonder most about how the registry can be done in VB...Would using system.management be a start? Or WMI? if so is there a nice VB sample..
View 3 RepliesI've been profiling a WinForm's application using ".NET Memory Profiler".I can't quite seem to understand how my application is growing to 1GB, then 2GB, then 3GB of usage - according to windows task manager.
The private bytes using that tool, and "Total Bytes in All Heaps" shows only as 70MB or so. At the top of my list of instances hanging around, they are mostly String, or WeakReferences to lots of little objects.
All the application is doing is showing a form that loads data from a database. I repeat the show/dispose cycle of the form about 100 times and the growth is continuous.I've tried about 3 memory profiling tools now and none of them are showing me where this enormous amount of memory consumption is coming from.
I found what seems to be an easy and effective way to reduce the memory consumption of my vb.net app. What I need to know is how "correct" or "proper" is the method I'm using for my application and what exactly is going on behind the scenes that I should worry about? I want to release memory every time a form closes. Here is how I reduce the required memory of my program:[code...]
View 7 RepliesTarget machine 4 core AMD I have an event that is raised my the main thread of the application. The event is consumed by several different classes in the application. I want them all to run concurrently up to the max cores available and then que the rest in order.The work routine in each class is relatively small but concurrency is the goal.Considering this.
A. Create a background worker on each classes initialization and have the event handler start the worker.
B. Create a delegate to the do-work sub that is called by the event handler
A- Pros - worker is only created once and reusable so only pay creation cost once.
A-Cons could create a ton of workers that consume resources eventually.
B- Pros Smaller thread pool
B- Cons Lot of overhead
According to the language specification guide for VB.NET Section 10.9.3. The enumerator expression in a for each loop is copied over into memory. If I have a list of 10000 objects that list will be in memory twice for the code below?
dim myList as new list(of bobs)
'put 10000 bobs in my list
for each x In myList
'do something
next
If I were generating the list from a linqQuery or some other such query it would make sense to generate that list at the for each loop statement thus not having the list in memory twice for example.
for each x in myList.where(function(x) x.name = Y)
'do something
next
If the LINQ query is unreadable on the for each loop, do I forgo readability and just put it on the for each loop declaration line? Should I declare the list in its own variable and just bite the bullet and have the list exist twice in memory?
I have a VB Function (in Visual Studio 2008 with .NET 3.5) that opens up a connection to an Oracle database and queries the database for information. Apparently after some trial and error, I discovered when the SQL statement is being processed and filling the dataset, it apparently is taking up too much memory trying to complete the task. I'm running into System.OutofMemory exceptions and other unpleasantness.I'm wondering, is there some sort of program out there to measure memory consumption of your SQL code that is being processed in a Visual Studio application?

View 2 RepliesI did a project (College Management) in vb.net 2008 which contains 13 forms in it. I designed the different functions in a different normal form, i.e. frmAdmission, frmSearch etc. When the project run's the main form is loaded. When user chooses a particular function say 'frmSearch' then the main form is unloaded and the form frmSearch is loaded. Now my lecturer told me to use MDI forms instead of normal forms because, normal forms takes larger memory than the MDI forms.
