Using The Shell Function In VB 2010 To Launch Perfmon?
Apr 22, 2011I'm trying to launch perfmon /res on a Windows 7 (32bit) install using VB Express 2010. When I use the line:
shell("C:WindowsSystem32perfmon /res", AppWinStyle.NormalFocus)
All I get told is that the file doesn't exist. IT DOES EXIST! ITS RIGHT THERE! If you try in cmd it works, if you go there in explorer it works, if NASA used an orbital platform connected to my c$ share and tried, it would work. If you get VB to check for the existence of the file using an if statement it finds it, then tells me its not there the very next line when I use shell to run it.

Aug 1, 2009I'm going to attempt to make a shell replacement for the Windows default shell: explorer.exe. I'm not sure if its possible using Vb.Net, but I can't seem why not. My end goal is to use a custom made shell for a Windows Preinstallation Environment instead of the default command prompt. I plan to use a 3rd party program to compile the program with the .NET Framework. Otherwise, it wouldn't work because Windows PE does not support the .NET Framework.

View 2 RepliesDateDiff Function Gives Odd Results For Negative Days?
Jun 9, 2009DateDiff for the interval Day gives expected results for days past until present, but if the first date is further in time than the second date, it gives the difference +1. Is there something I'm doing wrong? For example, if I put in today for both, the difference is 0. If I put in yesterday and today, I get 1. This is all expected, but if I put in tomorrow and today, I get 0, and two days from now and today give -1. Why is the function giving altered results if the date is negative?
Here is the specific code.
Private Sub DateTimePicker1_ValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DateTimePicker1.ValueChanged
TextBox1.Text = DateDiff(DateInterval.Day, DateTimePicker1.Value, Date.Now)

Show The Final Results Instead Of The Results Real-time
Sep 28, 2010I have a form that allows users to select file and then it reads the contents, parses the data and then executes a sql insert statement to add it to a database. What I am having issues with is showing real-time results. Currently, I have the import operation take place on the import form within the OnLoad event. The problem with this is it only shows the final results instead of the results real-time. Is there anyway to do this without creating a seperate thread and delegates?

How To Pass A Function To A Function Is Functors/function Objects Avaiable In VB2010
Oct 12, 2011I want to make an numerical integration method with takes in an analytic function and integrate it over a specific interval. For the numerical integration procedure I want to use some procedures in nr.com. The problem is that these are programmed in C++ and they uses functors to pass a function to the integration method. How can I do this in VB 2010?
I want to initialize the function (i.e. set a=1,b=0 for function y(x)=a*x+b) and then pass the function to the integration method. Then when the integration method call the function it only calls the function with one parameter (i.e. x since a,b is already set)
What is the best way to do this in VB2010?I want to make a general integration method where I can pass any single valued function and integration limits.
I have just started using VB, and from what I have found so far it seems like the tools you have is
- to us a delegate for the function
- to use a lambda expression for the function
- send a pointer/adressOf
- to create a function class/structure and submit this to the function
As for now I am most inclined to create a function-class. But I am not really sure how.F.ex. I make different classes for each "uniqe function" I want to integrate, but how can I pass them to the integration function when I need to specify the argument type in the integration-function-call?This seems like a basic problem which applies to many Math operations, so I think it would be very useful to clarify this.
Function Syntax - Call A Function With 2 Arguments When The Function Is Only Defined For One
Apr 1, 2010I'm trying to undersatnd the syntax of calling a funciton and it seem confusing when I'm using a web service in ASP.net. Maybe this question should be in an ASP forum, but it is a VB question. This simple web service allows you to type in your name and it response with an alert box with you name.
My question is, How can you call a function with 2 arguments when the function is only defined for one. I understand that the second argument is actually a method that handling the respons, but how can you interchange function arguments for methods and how do you know that there are methods for

AccessViolationException With Shell To Explorer
Dec 15, 2010I wrote a backup utility that synchronizes a list of folders. Errors appear in a list. In the list I can right-click to retry, exclude the folder next time, or open the folder in explorer to examine.When I shell to explorer I get an AccessViolationException. Form1 opens Form4 with Form4. ShowDialog(), and that's where the error occurs. The error does not occur within Form4 where the shell function is called. memory must be getting trashed somehow.I've used two methods, Shell and System.Diagnostics.Process.Start. Each produces similar results. Shell waits awhile before causing the error, but Process.Start causes the error immediately.This is VB.Net 2010 using framework 4, though I did resolve a shell problem once before with VBA by writing out a VBScript file then shelling to the VBScript file.

This is VB.Net 2010 using framework 4, though I did resolve a shell problem once before with VBA by writing out a VBScript file then shelling to the VBScript file. I don't think the process being started is isolated enough. It's sharing memory or something else.
