2008 DLL Passing Data Among Different Exe's?
Oct 15, 2010
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 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'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?

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 have 2 forms. Using Visual Basic.On Form 1 there is a populated combo box. This was done so by running a query through it and populating it with PUZ_ID values from a data set.On form two there is a tool strip and below is a search query.I need to be able to select the value i want in the combo box on form 1, and launch a button that opens form 2, which has loaded the data that i binded onto the form.Anyone have any ideas/code or need me to clear this up a bit more?So i need to run something through a query, or make something public or what?

I would like to have custom methods to pass data between function, or to keep it in memory throughout the program.
Example:
Private function info()
Addr1 = addr1.text
Addr2 = addr2.text
City = city.text
[code]....
Could I run this function towards the beginning of the program and use it throughout until the form is disposed? I can't seem to get the information to stick once I get out of the function, I will need to use the same information multiple times throughout the application so I figured if I could make a function to keep the info rather than declaring the 5 lines in every option but anytime I call the method, it fills it correctly then when I get back to the main function the info goes back to 'nothing'. is it possible to pass data around between functions like you could in Java?

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.

In reference to this post [URL] I have another more specific question about passing data between forms in VB.net I have a form with over 50 variables that I need to access on a second form and if i followed the method above, my form 2 will end up way too long and time consuming. I'm making a complex calculation software that prompts user inputs values and calculates all those unknown variables. I need to display all the resulting values in the 2nd form. and from the 2nd form , i want to give the users an option to export all those values to an ms Excel sheet.
