Finding The Input About Program Workflow?
Sep 18, 2009
I have a program that pulls orders from the database and prints packing slips and labels for the warehouse. There are 2 reports that print out every time and the are potentially 7 others that could print for each order. all of the reports will use the same basic information and just present it in different ways (i.e. label, packing slip, international paperwork, etc). the program we are currently using was written in a rush and I know is not efficient. I am pulling the same information several times for each run. I am trying to redo the program the correct way now. What I am asking input for is what do you think the best way to approach this is. I am currently using the System.Collections.DictionaryBase to store all of the information I need. I am thinking of creating more of those to store the information for each of the reports, but that still doesn't seem like the most efficient way to do it either.

I am trying to see find out if a user has been inactive for a certain amount of time by mouse and keyboard events. I want to be able to find this from windows not my form. I am lost as to where to start. I came across this "GetLastInputInfo Function" but am not sure if that is right and/or how to use it.

I have worked on .NET 2.0 technologies and now that I want start learning newer technologies, I am currently very confused on how to proceed.
New technologies I am considering consist of AJAX, Workflow, WCF and WPF
Here is my dilemma:
1. Where should I start first?
2. Which technology would allow me quicker understanding?
3. Is there any specific sequence to this learning?
I understand the questions might be stupid; however, this would help me concentrate on one instead of all over the place and archiving nothing.

I'm making a workflowdesigner to create workflows on a canvas with wpf and vb.net. I have made it possible to draw lines(relations) between objects with a nice function. Now I want to implement a way to delete a relation. I add a onclick handler on the shape but the line is very thin and hard to click. I've heard to draw 2 lines 1 with a thicker stroke thickness, but this isn't possible since the drawline method is heavy on the cpu.

I'm implementing a State Machine in WF 4.0. In some transitions, I have added a condition where I check that some variables have the expected values. The variables are enums and booleans, and everything is fine.
However, now I tried to evaluate when a property is null. I have and argument in my workflow, let's say, 'MyArgument'. In a transition, I try to put a condition like 'MyArgument.MyProperty = Nothing'. I never developed in VB.NET, I don't know if I'm missing something here...
VS2010 gives the following error: "Error 4 Compiler error(s) encountered processing expression "MyArg.MyProp = Nothing".
Operator '=' is not defined for types 'XXXX' and 'XXXX'
The type names are exactly the same, and I have debugged VS2010 to ensure that my assembly is not loaded from 2 different locations.
How can I check if the property is null or not?
BTW, I'm using VS2010 SP 1, with .NET Platform Update 1 installed, on W7 64 bits.

I am developing an app that uses a sql backend database (hosted on a different machine).The app I am developing will be run on 10 different workstations simultaneously.Sometimes the app will change the database in such a way that the database needs to initiate a workflow process and I'm not sure of the best way to do this.Also, when database changes happen, how does one best notify the other app instances that the change has happened, so they know to refresh their data? I was thinking that triggers could help initiate the workflow but it might be nice to develop the actual workflow in .net code.Should I write another App to run as a service on the server and do the work and also to tell the client apps when things change?

I have a procedure at the end of my console application that ask the user to either hit enter to end the program, or type s to perform another search. The issue I'm having is no matter what the user types in the program end. What I would like to happen is if the user types s, then the program starts over and lets the user perform another search. The program is procedural and I need to find a way to start back off at the top of the program which ask the user to type a name to search.

I needed to make a program for finding prime numbers. The logic is that you have to put limits n & m and then LOOP and odd-integer P between n & m inclusive. I have a button to click on my form that displays 2 message boxes, one saying " enter upper limit" and the other say "enter lower limit". I need now to get the results of the odd prime numbers between the limits into a list box!
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

I know how to check for the version information from inside a VB2005 application:
Dim version as String= String.Format("Version {0}", My.Application.Info.Version.ToString)
That works fine. But let's say I have two applications, A and B. App A wants to find out what app B's version is. Is there a way to do that?

I'm tryng to figure out a way how I can stop my code from running while I wait for input from a device.Networked device that sends data to .net app.I now wish to prompt the user to answer a 'Continue' questoion and select either 'Yes' or 'No' on the device. This is transmitted to program over netstream.I want the code to pause though while waiting for an answer as different routines are run dependent on the answer.

I wanted to know if there was a way putting items into input fields on another program?
For example, if there is a login form, I want to be able to submit the user amen and password into the fields.
The program is a console program that only accepts keystrokes. It's a program for my work and I want to be able to login to the system, pull up reports and put the results into my form.

How can you access the webcam and microphone in VB.net, assuming the user even has one?
I fail to see a My.Computer.Webcam or My.Computer.Microphone, both of which would probably have been a nice addition.

I am new to VB.Net and programming all together. I am trying to make a program that will take 2 numbers input by the user, Add them together and display the sum. Then take the sum and divide it individually by each number to give you what percent of the sum the numbers are. I'm working on making it a program that will calculate the Hardy-Weinberg equilibrium for my Anthro Class. I'm just doing this for practice for my VB.Net Class. But i will move onto that at a later time. I just want to finish this first.
So.. Here is my code so far. It's not complete yet but this is should be enough to make it function.

i did this much but something doesn't seem right...the question is A Visual Basic program that requests a positive integer as input, and carries out the following steps:If the number is even, divide it by 2.Otherwise, multiply the number by 3, and add 1 to the result. Repeat this process with the resulting number, and continue repeating until the number 1 is reached.After the number 1 is reached, displayed how many iterations were required to reach the number 1. (Hint: a number is even if number Mod 2 = 0.)

I've been working on a program that takes input from a textbox, removes the punctuation, puts the words into an array (using the split method), and compares the array against a reversed copy of itself to determine if it is a word palindrome or not. I understand the logic, but I'm getting kind of caught up as far as what code to us. This is what I have so far, but no matter what I enter into the text box, nothing happens. I'm completely lost as to what I'm doing wrong.
