VS 2008 : Passing Values Between Forms Inside A DLL?

Aug 5, 2009

To start things up, I have a DLL called clsEmployeeModule, containing forms frmEmpInfo and frmAddEmpName. frmEmpInfo contains a textbox that when clicked displays the frmAddEmpName. Now the latter contains three textboxes (firstname, middlename and lastname) and a Save button. Once the user clicks Save, the values from the three textboxes will be concatenated and displayed as a full name back in the frmEmpInfo form.Below is the code snippet calling the frmAddEmpName:

vb
Private Sub empname_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles empname.Click If genInfo_edit = True Then call_addempname.Text = "Edit Employee Name" End If call_addempname.Show() End Sub

And here's the code snippet from the frmAddEmpName:

vb
Imports clsEmployeeModule Public Class frmAddEmpName Dim callempinfo As New clsEmployeeModule.frmEmpInfo Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click mnFname = firstname.Text

[code]....

When I debugged the program, it showed that employee_fullname was successfully populated with the concatenated values -- however, that wasn't the case for the empname textbox.

Passing Values Between Forms

May 27, 2009

I think I'm getting hung up on syntax here. I've got 2 forms and am trying to pass a textbox value from the 1st form to the 2nd. The textbox value is an unique ID #, so it's an integer value in the database. The ID displays in the textbox just fine on the 1st form. When I try to access the value of this ID textbox in code in the 2nd form, I see that the value is empty, or equal to "". But I see a valid ID # on the 1st form. Here's the code that shows me that the textbox equals "".

Passing Values (integer) Between Forms?

May 1, 2012

My problem is that I have two forms, Form1 and Form2 ...on Form1 there is a TextBox called txtTotal (this contains the calculation of Ticket Prices, thus it's a numeric value) and on Form2 there is a TextBox called txtTotal2. All I want to do is get the same number that appears in txtTotal on Form1 to appear in txtTotal2 on Form2 .However whenever I try some of the help tips online such as using a declaring txtTotal as global or friend it dosn't work, and any other code iv tried attempts pass the textbox value as String which brings an error.

Winforms - Passing Values Out Of Forms?

Sep 8, 2011

I have a very simple windows forms setup. Form1 has a progress bar and a button on it, when clicked the button opens Form2 which also has a button on it that launches Form3. On Form3 is a button which I want to use to raise an event back to Form1.To achieve this can I add an event handler on form1 that will listen for an event of the type raised in form3? Or do I have to pass references to form1 to form2 and then from form2 to form3?

Using Multiple Forms In A User Control And Passing Values Between Them?

Feb 6, 2012

I need a nudge in the right direction. I have a user control that has the main form and it calls a secondary form to gather some additional information in some cases. I need to pass the information back from the secondary form to the primary user control form so I can validate the data and save. In the secondary form, I have the following code:

Dim myFrm as new frmOperationComments
myFrm.OperationComments = [comments from form]
myFrm.OperationDate=[Date from form]

I have tried creating two public properties on the user control and setting them, I have created two properties in the user control form called OperationComments and OperationDate. I can set both of them, but when I close or hide the form and go back to the main user control form, the values for these properties or variables are not set. How do you set the values on the main form from a calling form within a user control?

VS 2008 Passing Values Between Threads?

Oct 26, 2009

I am trying to get into vb.net but having an issue getting a variable value from a class library in a different thread.

What I am trying to do is create my own Winsock type control for my own use. Once data arrives I try and pass it back to the main application so that I can read it and process it.

So far I cant get it working at all. I have tried the following

Raiseevent

I try passing the value as a variable in the raiseevent property. This triggers an error about the value being in a different thread, I always thought that it would create a new variable in the thread of the application it was raising an event in and copy the value.

Function

I have tried writing a function into the class that I call (much like how the winsock control works) so that the class can return the value to the main application.

aka
strData = Myclass.GetData

in the class it returns the value and clears it from its own local variable. This however means the value returns to the main application as nothing even if I step through and see it assigning a value.

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?

VS 2008 - Sending Data / Passing Value Between Forms

Dec 15, 2009

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) ?

Add Values Inside Textboxes That Are Located In Tables In Program 2008?

Nov 11, 2009

Can you add values inside textboxes that are located in tables in Visual Basic 2008?

I put a TableLayoutPanel on a form and inside the Table I put textboxes. Outside the table there is a button. The whole point of the program is so that the user inputs numerical values inside the textboxes and then hits the button and the answer comes out in another textbox. But its not working. It worked when I didn't put my textboxes inside the TableLayoutPanel.[code]...

VS 2008 Forms Inside Form, Snap To All Edges?

Sep 9, 2010

I have multiple forms within a form, typically up to 16, and I want these "inside" forms to snap all edges between eachother or the parent form edges, when a form is resized or moved, and edge comes within x pixels of any other edge.How should I approach this? What I can think of is to raise an event on the form that is moved/resized which calls a parent form handler method that loops through all the forms, check the edges and then keeps fixing (repositioning) the active form if any of its edges is close to any other form edge

Passing Data Between Forms Without Any Public Methods Or Properties On The Forms

Dec 28, 2009

Passing data between forms without any public methods or properties on the forms. everything but the "Controller" class, which I would like you furnish. I just changed the title from "Intermediate" to "Beginner" This solution is an example of the Observer Pattern. The "Controller" class is the "observed" class, which in this case means it publishes events.

' File Definitions.vb

Public Delegate Sub MessageDelegate(ByVal sender As Object, ByVal e As MessageEventArgs)

Public Class MessageEventArgs : Inherits EventArgs
Public Message As String

[CODE]...

The program should initially display Form1, and Form2. Clicking of the button on either form will modify the Title Text of both forms. I think that you will find the final end result to be pretty neat, as it works with any number of open forms not just two. I think asking for the Controller class is easier than asking for the code in the forms. My solution for Controller class has 7 lines of content, 9 lines if you include Class, EndClass. A minimal solution could achieved with only 4 lines of content, but it would a textbook example of bad programming.

Passing Values To Java?

May 10, 2009

I'm pulling up a a webpage in a control and the page is full of Java functions. I'm able to use execute a function using invokescript. That works out really well. But here's the thing. There's a function that takes the value of a rendered textbox and uses that data to perform the function.The textbox is usually hidden until another function activates it to enter data.What I want to do is to bypass having the textbox come up and execute the function with predefined data. Basically the function refers to the data it gets as txtWrapupComment.value whereas txtWrapupComment is the textbox it's getting its data from.

So, the bottom line, is there a way I can declare txtWrapupComment.value and pass it before I execute the funtion?
