View 2 RepliesJust started VB programming this week and have found a wealth of information about what I'm trying to do. Problem is, some of it is more complete than others.Here's what I'm trying to do:In Form1 (my main form), I want to instantiate a class that contains a couple of properties (speed setpoint and position setpoint). When I click a button, I want to pass this data to Form2 and populate two textboxes on Form2 with the properties of this object. I want to manipulate the property values on Form2 and click an OK button which closes the dialog and returns the manipulated data, updating the property values of the object. Here's the algorithm I'm following:1) On Form1, instantiate the class2) On Form1's "Pass Data" button click event handler, instantiate a Form2 object and invoke the ShowDialog method, passing the object as a parameter.
3) On Form2, overload the ShowDialog method to accept the object as a parameter and modify the method so that it returns the manipulated class data.4) On Form2, in the ShowDialog method, populate the textboxes with the class data that was passed in.Here's where I get stuck. If I press the OK button on Form2 (DialogResult.OK), it returns me to Form1, but what hook do I have in Form1 to receive the manipulated class data that the ShowDialog method is returning?Here's an example of what I'm thinking about:
Code:
Public Class Form1
Dim clsController1 As New MotionController

I'm sure it's probably a very elementary question, but every explanation I've found seems to be incomplete.
I'm trying to program in a true object oriented manner and its causing me to re-learn a few things. Specifically, I'm having some trouble with error handling. I have all of my data access being performed by an adapter class in a seperate project. I can catch duplicate records without any problems, but I want to be able to send a message back to the user. Here's what I have so far:

View 1 RepliesI have some code that works in winforms, but not in WPF apparently, the code is as follows: This is set globally:
Private Property avar As Object

And then in the Window Loaded sub, this is placed:
charchoice = main.charchoice
Thing is, the next window doesn't pick up this variable, so how can I make it recognise and use it?

I'm sure this is possible but I've got no clue of what I'm looking for to even start to learn this. Basically I want to create a form that can load data from one software application and feed it to another.
Is it possible to change settings in other forms by another piece of software like if there was a flag = True and I wanted to change it to flag = False or instead of loading Dim processorID As String = String.Empty I can input Dim processorID As String = 1234

I have two VB projects in one VS2010 solution. The first program brings in about 60 integers every few seconds from my PC's serial port. The second program, published via Click-Once and running on my customer's PC, needs to see that new data every two to five seconds.
Is there a simple and reliable way to accomplish this, staying with VB? WCF is way over my head.
I am developing an application for internal use in our company. The purpose of this application is for document imaging. What we are wanting to do is print a barcode label to attach to documents so that when they are scanned in a piece of software such as vfiler will be able to read the barcodes and know how to file them.The main focus is our ERP system which is web based (PHP). We are wanting to modify the code to allow the user to print the barcode label immediately once they enter an order or PO. I have access to the source code for the ERP web pages. I don't know of any way to make a web page print to a printer without displaying the printer select dialog. So, I decided that I wanted to try and create a VB application that would do the printing of the barcodes. This would allow me to bypass the the printer select dialog.
Now for the question. Is there any way to have a web page (PHP) running on the server call a VB app to perform a task? So, if I had a button on the webpage and the user clicked it, that button would somehow send the pertinent information (Order number) to the VB app and the VB app would print the barcode. The VB app will always be running on the machine. The label printers will be Zebra USB label printers on each person's machine.

View 1 RepliesCan anyone suggest me how to pass datagridview data to database.
Process must be like this, if the user enter multiple data into the datagridview after user press "save" button, datagridview data must be passed to database. Need C# code in windows application. It should have some comboxbox control in datagridview.
As we pass data to a database in a clear cut way, there may be situations, when we might fear data stealing. So can we simply encrypt data at the time of insertion, so that the data privacy will be maintained and the front end can only see the data.
