Imagine a project with couple of forms and a module. Now as per my knowledge if i want to send some data from one form to another then :
- If I declare variable friend/public in a module then it can be accessed in the entire project (thus also between forms).
- If I just have to send data from one form to another, then I can call the other form's sub/function and pass value.
- If the pass value by reference then I can get new value only if its changed in that function.
Now what the issue is, I need to pass a variable to a form and in that form when user types contents in a textbox or makes other selection and presses OK button then it should return some values back to the calling form. Now how can I achieve this (without declaring global variables which will be accessible everywhere) ?

I'm trying to create a UserControl in ASP.NET to display news items based on two values that are passed in, NewsTag and ItemLimit. The problem is that the SQLdatasource is not picking up the properties in SqlDataSource1_Init. Instead the calls to the properties are empty when this is called but after render have values.
<script runat="server">
Public Property NewsTag() As String

I am using VB 2010 express and am trying to make a program for a project that generates lottery numbers in a specific way. What I have is two forms. Form one has two text boxes and a button. Form two has a checkedlistbox that is pre-populated with numbers from 1-56. What I am trying to do is have the program open to form1, the user presses button1 ("Select Numbers") which opens form2. From there they will select numbers they want to pick from (narrowing their pool of lotto picks to only numbers they want to use). Then when they hit select, I want the numbers they have checked to return back to the textbox1 on form1. HOWEVER, I also only want 5 numbers, randomly selected, from the pool of checked numbers the user selected on form2 to return to the textbox1 on form1..... I may be in wayyy over my head, but I have all of the forms designed and I have been close to getting the forms to at least communicate, but still far from doing what I have described I am trying to do.

I have two UserControls on a MasterPage. DataEntryUC contains several TextBoxes and DropDownList. NavSaveUC contains navigation buttons. When the user clicks on a navigation button, I will be saving the data entered into DataEntryUC from the NavSaveUC UserControl.
I have a couple of tables in my DB that contain stored procedure names, control names, control types, SqlDbTypes, etc.... that correlate with DataEntryUC.
How do I reference a text box that is on DataEntryUC from NavSaveUC?
I have been working on the following code from NavSaveUC with no luck.
Dim MyControlName = "txtFirstName"
Dim MyControlType = "TextBox"
Dim MyStringValue as String

I've code this code below:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim hwrRequest As HttpWebRequest = HttpWebRequest.Create("http://www.example.com/web-service.php")
[Code]....
The MsgBox() at the end shows the response, which as I've added to my script, echos the result from the $user and $pass variables which are supposed to retrieve those details being written to the stream above, but they show up empty.
I'm retrieving those values by doing: $user = $_POST["user"]; $pass = $_POST["pass"];

I have a program that I collect data using a com port. I display that using special visual controls - no problem here.
What I would like to do is to send this same information out over the network via ethernet to another PC located in another room.
I presume I would have to have another copy of the program on the second pc as the information is simply duplicated but I am not sure how to get the data out of one to the other

I have written a class library that creates a dll to pass data back and forth within the same compiled instance exe. Is it possble to configure this Class Library in order to pass the data produced in the first instance of an .exe to other instances exe programs written in VB.NET?
My first thought was to add a Module. Older versions used Declare Files. Is there something in the compiler that I should set where the variables point to a specific memory address, or something..., that makes the variable available to other VB programs running in a seperate instance?

I am having trouble sending data to a comport..... I am a noob at this and have been doing my head in... I have done a fair bit to a few programs that I have on the go, but am stuck at sending some data to the comport...
I have in form1 put the serial port contol and added SerialPort1.Open() to that. I have then added 3 buttons that I was to use to send data to the port... Since this is for a radio scanner the buttons turn the backlight on / dim and off.....
LTN is used to turn the light on and works fine in hyperterminal.. I have got the port settings right in vs2008 but the code is wrong.

I have returned to a project I started a while ago. I have a small members database showing basic info (Title, Forename and Surname) in a data grid view with all data populated from a SQL database. I have the dataset populated with all this info as well as other data through the use of relationships/foreign keys (Addresses and Telephone Numbers, etc)I have tested the relationships using a simple form which shows the correct addresses, telephones, etc for each user as you navigate through it.
I now wish to show just the datagridview on form 1 which is read only with the row select set to full row (I have done all this so far). I have also set up a second form which displayes just the relationship data.I want to be able to load the second form (with the address and telephone number data, etc) when the row is double clicked by the user. ie - if row 15 is double clicked on, then the second form should load the address and telephone number data for record 15.

Form1 is a Datagridview which is non editable. I want a user to be able to double click and open Form2, which will allow editing BUTForm2 is a list view and also had a binding navigator so I guess I cannot use dialogue? I do not want to simply just edit in a dialogue and save.Is there an easy way to get the record from Form1 and pass it to the controls in Form2 so that the correct record is displayed?

I am trying to pass data between forms on a double click operation. On Form1, I have a simple database with three fields (ProfileID(PK), Profile First, Profile Surname). The database has 10 records at present which displays all records in a datagrid view which is set to read only. I have the Selection Mode set to FullRowSelect to highlight the full row.Form2, is a form to Display one record at a time. This form allows editing and saving of changes.How would I go about coding in vb.net to firstly get the ProfileID from the relevant row and send this into Form2 to display that record for editing?

I have a very basic knowledge of coding, just enough to understand some PicBASIC Pro and program a microchip to send the values of some variables to a PC via the com port. I've used a terminal utility like Hyperterm to confirm the right variables are being sent, so I thought it would be cool to have a custom application on the PC to display these variables, and possible set them via the application by writing the new one back to the PIC. So I downloaded VB express 2008 - and whilst it was "simple" to draw a box and add a few text boxes I'm lost at how to actually do anything practical with it
[Code]...
Could someone advise me in laymens terms exactly what I need to do inorder to populate the text boxes with the data from the PIC micro. Whilst I understand the basics about BASIC, I have no idea on things like classes etc

I've got a main form (Form1.vb) where I created some controls (with the Designer).I've created a class myTextBox, inheriting from TextBox, in myTextBox.vb.In the main form, I call procedures from myTextBox. The issue is, those procedures use values from the Form controls. So the class doesn't recognise them as initialised.What's the best solution for this?I think I could pass the object itself as a parameter but doing it on each call seems a bitredundant and it thickens the code.Is there any way to access the Form1 controls and objects directly from the myTextBox.vb class?

I just discovered the joys of UserControl's and I was wondering if it is possible to populate the usercontrol with data from a database in the UserControl's Form.Load event instead of the form the userControl is placed on. I feel it would make using the control a lot easier if it just populated itself without anymore code.I tried it with a ListView but it gave me a bunch of errors, so I didn't know if it had to be done a certain way or if it was just one of those things that doesn't work no matter what.

I've made a user control (http:url.....)I'm trying to format the text based on the data type e.g.:
Date
Numeric - 2 Decimals
Numeric - 0 Decimals
String
Now, I've added a property so that the user can decide at design time, what format he wants for the textbox. I've also made the options an enum. And then the coding in a sub. But not sure what I have to do with the sub.When I put it in the TextChanged event, then I get the weirdest behaviour from it.LIke when I typed in 1234 on Numeric0Decimals, after I typed 4, the cursor jumped to the first position of the textbox...On type Date, I just type in 2009/08 and then again it just jumps to the front and set the text to 01/08/2009 .So obviously can't place the sub in the textchanged event...
Private msTextConversion As TextConversionOptions
Enum TextConversionOptions
DateType[code]....
I'll obviously still change my sub to make sure that the text entered is numeric,or string, or valid date etc. Just didn't get around that part yet.

Is it possible to have a Textbox on a form that when the user inputs data, ( during Runtime )that data remains in the Textbox for good and the Textbox then becomes read only ? Is it also possible to make it so that the CD with the programme on, is in the PC when the programme is being used. Perhaps writing the Textbox data back onto the CD ?

I need to control a device with a GPIB port. I have the commands that I need to use to do this; but I don't know which is the sintaxis in Visual Basic.
For example if I need to send a instruction like "START:0.01" to the external device which are the libraries that I have to include?, how should I write the programming line to do this?
The main tasks that I need to program are sending data, receiving data, and saving data
