I'm working with an eprom emulator in trying to understand the command string write instructions. Here is what I have. [code] From what I know, the values in hex need to be converted to decimal first. What I'm not sure about is the checksum value needed. The instructions say Checksum =(1 byte truncated addition of all the above).

So what I've been trying to learn how to do is create a command console program so when I open it up it will execute a series of keystrokes, i.e I want to create a program that when I open it a cmd will open and automatically open up itunes and press podcasts the ctrl u to update them. How would I could that?
View 1 RepliesWith much help from the forum I am almost there with my project to emulate a cmd console using a form with a textbox (txtResults) to display the output of the (hidden) console, and another textbox (txtCommand) for me to type in commands, and send to the console with a click of a button (Button1).
The following code now almost emulates the cmd console exactly, but just one little bug still to iron out:
Look at the following pairs of screenshots from a cmd console and my emulator, and you will see the difference.

I found out how to get the emulator working for my kinectmultipoint on 32-bit and 64-bit machines (i still need to confirm 64-bit by tests but 32-bit works). I used the webbrowser controls invokescript property and placed my vbscript code in an html page to tell internet explorer engine to pass script to correct version scripting engine when executing the vbscript.
after using navigate property I use these lines of code:
In form load: 'setup the softehci controller before executing dsf code!
Shell("C:Program Filesdsfsoftehcisoftehcicfg /REMOVE")
Shell("C:Program Filesdsfsoftehcisoftehcicfg /REMOVE")
In button1 click event: Webbrowser1.Navigate("path to html file with vbscript")
Webbrowser1.Invokescript("my vbscript method")
Note: i think this approach only works in local mode not on a web server or such.
So if anyone wants to check up on the project or help me i just need to change the vbscript to add multiple mouse devices and then i portion it up to do these three main functions:1. Add a new mouse device when kinect detects another person walking up to computer.
I am writing an application that has to read and interpret data stored in some PDF files. The reading part is done but I am only able to get a dump of all the words on a page and not the format of the words. What I mean is that if I have to extract a table, I am getting the numbers in the table but not the markup which defines the table.
Further, there is some formatting used which displays a few of these numbers within parentheses (meaning that those numbers are negative) but the parentheses themselves are not part of the text. Hence, I am not able to distinguish between positive and negative numbers present in the PDF table!
How do you get the PDF markup along with the text? Is a PDF similar in structure to an XML with tags used to markup tables etc.? If not, then, is there a resource which describes the salient features of the PDF DOM? I am using VBA and the Acrobat library (AcroExch etc.)

View 1 RepliesMy goal is to read a data streaming from a machine the streaming is divided in tre main parts,the first is a 10 byte array that declare the length of the second and third part.The second one, the header, is a 22 DWORD (*32bit) ( 88 byte ) structured of mixed data types.I can easly read the value inside this header when the DWORD contains just one information using something like: [code] My problem starts because some of these DWORD contains several indipendent informations, for example DWORD #4 [ channel 2 peaks 31..16] [channel 1 peaks 15..0].For what I understood the first 16 bits ( so 2 bytes) are used to store the information of the first channel , while the second 16 bits are used for the second channel, I tryed converting the first 2 byte with System.BitConverter.ToUInt16()but without success.Can someone explain me what to do and how these numbers are supposed to be stored?
View 6 Repliesso i have a class called FOOTBALL,then another 3 classes/forms that inherit FOOTBALL, they control score (SCOREBOX), possession (POSSBOX), and quarter (QUARTERBOX).the FOOTBALL class has 4 variables, "score" (array of 2 ints), "teams" (array of 2 strings), "possession" (boolean), and "quarter" (int)after that i have another form called MAINBOX, which creates new instances of the 3 classes (SCOREBOX, POSSBOX, and QUARTERBOX) (like this: private scoring = new SCOREBOX)... however they all technically create their own FOOTBALL classes, so I cannot connect them.

It is my understanding that in .Net 4.0, VB will have an in-memory compiler.

i am running a Sub which takes as arguments a Datatable and a String.
Private Sub Populate(ByVal dttemp As DataTable, ByVal strWhichPart As String)
At one point there is a combobox which is populated with some of the data in the datatable. The name of the combobox is cmd plus the name of the string for example when the string is Person_FirstName the name of the combobox is cmbPerson_FirstName.Then i add items to the combobox like this:
cmbPerson_FirstName.Items.Add(strHold(rr))
My question is this can i make a String into a command? Because i have many comboboxes which have the same name as the string argument of the sub how can i do something like this to work
strWhichPart.Items.Add(strHold(rr))
in which strWhichPart is a string. Is there a command that i can execute a string as a command?

If i have a class called A and a class called B, if B inherits A that means A is the super class and B is the subclass. I have been asked to describe why class A is not an abstract class but as i see it class A is an abstract class A, as it has been created for Class B to use in the future, is it something to do with Class B not being able to access the fields in Class A as although they are private by default?

As far as I understand from the docs, it seems that Application.Run() starts a message loop on the current thread, which in turns enables it to process user input (Is that right?).The overloaded version Application.Run(Form) basically does the same, only it exists when the form closes, and it shows the form by default.timer ticks after 20mns, and has to execute say approx. 15 tasks one by one, every time creating an instance of a progress dialog, initially hidden in the taskbar.

I expect to get a runtime error, because And evaluates both conditions, which is why in this case AndAlso should be the better operator to use. When I try this code there is no difference in behavior between 'And' & 'AndAlso'. In neither case I get a
runtime error, not even when I flip the conditions around. Is this by design, a lucky accident, or do I just not get it?

View 2 RepliesI have a situation in a program I'm writing where I'm not sure of the best way of coding a couple of objects and was hoping for a few pointers.I am using VB.NET 2003, so F/wrk v1.1. My business is horticultural in nature and I'm trying to help streamline the business with a new order fulfillment app.In my program, I have products. Some products don't have any component parts, but others are made up of a selection of plants.For example: we sell a trowel, which obviously doesn't have any component parts. But we also sell a large vegetable garden, which is made up of, say, 20 rocket plants, 30 salad plants, 5 spring onions, etc.[code]I believe the ProductContents table is technically referred to as a 'join table'?
I have written the classes in VB.NET which load, save, edit the Products and the Plants. I also have Manager classes which store collections of these objects (ProductMgr, PlantMgr).I have dealt with situations before with join tables where there are only two columns which are both FKs and both make up a composite PK (ie - to express a one-to-many relationship). This is pretty straightforward (using my product/plant tables as an example) because when I load an individual Product from the database, I also run a second SELECT query which returns any PlantIDs associated with that PlantID from ProductContents. I store that in an array of integers within the Product object. I can then load Plants from the PlantMgr object based on the PlantIDs stored in this array. I kind-of do the reverse when I save the Product to the database, I run a second INSERT query which updates the ProductContents table with the Plants associated with the Product.Where I'm getting stuck is with the inclusion of the extra 'Quantity' column. I can no longer store the PlantIDs in an array of Integers because I also need to store the Quantity associated with that Plant. I also can't use the PlantMgr object any more (to express which Plants are in each Product) because it also doesn't include any information about Quantity.I was just wondering if there is a standard way of handling this kind of situation, where I have a 'join table' which also includes extra columns as well as the two columns that identify the join.

I am working on a project, but the latest enhancement to it has me stumped currently. Here is what the class enhancement asks for:
Modify class time to provide a Tick method that increments the time by one second. Also provide methods IncrementMinute to increment the minute and methods IncrementHour to increment the Hour. The Trick method, the IncrementMinute method and the IncrementHour method should be called when you click the Add 1 to Second button, the Add 1 to Minute button and the Add 1 to Hour button, respectively. Be sure to test the following cases:
A) Incrementing into the next minute.
B) Incrementing into the next hour.
C) Incrementing into the next day (that is, 11:59:59 PM to 12:00:00 AM).
Here is my GUI:
The reason I am confused is currently my program already increments the seconds, minutes, and hours correctly (as shown in pic) for Cases A, B, C. But, I haven't added a Tick method which is what the enhancement to the class Time calls for. Here are the 2 classes I have so far:Time Class that the Tick method is supposed to be added to
Public Class Time
' declare Integer instance variables for the hour, minute and second
