Transferring Multiple Information From Form To Form?
Nov 3, 2011
So my question is that I have 2 list boxes in two forms aside from the main one. and I am trying to transfer what I choose in the side form to transfer to the list box.
several questions: Why does the blank list form I have in the main form create a problem when I enter a name for the list box and why does it appear in the box when I put it there? As you can see in my errors. It doesn't seem to recognize the listbox that I wanted to leave empty in the main form.
Second question is how do I get names to add in the main form list box. I believe I have the right code but I seem to be missing something else as well. I want the names to display in the main list box and the integers to add up together so I can separately figure the tax and shipping myself.
Here are some pictures and codes
Main:
Print:
Audio:
Public Class MainForm
Dim frmAudioBooks As New AudioBooks
Dim frmPrintedBooks As New PrintedBooks
someone give an idea or guide to do this: i have two forms. First form is used to ask from, to, departure time and how many people we want to book for. Second form is used to ask for each person that we book what is their name, age, title, phone number. i planned to use a loop to loop form 2 to ask for their info. However i woner how we can do this?? can a form be an array to loop??
The first form in my project is a simple form for a shop selling cars. At the end of the form is a text box called txtTotal.text, this is the total cost of each sale. When I press the print button I not only want to print a sales invoice(I have that bit done) but I also want the total in txtTotal.text to be added to lblDaysTakings on my second form called frmAudit. Ive searched the web far and wide and cant find anything either suitable or within my level of understanding.
Ive tried code such as
Private Sub cmdPrint_Click() Dim curTotal As Currency Dim curDaysTakings As Currency
[code]....
and several other combinations but Im obviously a mile and a half off track as Im not getting anywhere?s a lot bigger than just the print button but I didnt see the point in posting the rest as I have everything else sorted out, its just transfering the numbers from one form to the other thats getting me.
Im having a problem when transfering values from form to form.Firstly I have a main menu form,click on a button to go to the dell components form.I choose the components for the computer and when i hit calculate the total is displayed in a textbox for my subtotal. When i press send it will send the sub total from the dell components form to the grand total and display it in the dell sub total in the grand total form.This part works ok, however, i go to the main menu and click on a button to go to the packardbell components form. Do the same again but when i press send, it will send the value to the grand total form in the packardbell sub total textbox but the value in the dell sub total textbox has vanished.Here is the code in the dell components form
Code: Private Sub btnSend_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSend.Click Dim frm As frmGrandTotal = New frmGrandTotal(txtDellSubTotal.Text) Me.Hide()[code].....
Finally, the other problem im having is on the main menu form when I click on the view total button I get this error: Here is the code for this bit
Code: Private Sub btnViewTotal_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnViewTotal.Click 'frmGrandTotal.Show() Me.Hide() End Sub
How do you pass one radiobutton from form 2 to form 3? Iv tried:
Private Sub Form3_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load If Form2.rbtnPatterned.Checked = True Then rbtnPatterned.Show() End If
But that doesn't work. The radiobutton selected in form 1 doesn't appear in form 2....
I'm taking my first (and only) beginning programing class for Visual Basics 2008. I'm working on my final project and have hit a snag. A little background info - I have been able to code everything except for two final steps (but they are my most difficult steps), on these final steps I've gotten two suggestions on other sites, one person helped me with the coding which I used for my form1, but it I still have several errors, and another person suggested that I use a module.
Here is the issue. I have totals on three forms that need to pass through to a final form, and once they are on the final form they need to show up in an itemized list and need to then be totaled again. I actually have a total of 5 forms including my first form aptly named form1, which incidentally is where someone told me I should set up my whole 'connecting the totals' form, and I believe the guy was on the right path with helping me but, I'm still obviously pretty lost on this last segment of coding. Since I had little difficulty with the majority of my project, I didn't think this last bit would be so difficult. I'm going to list my coding for each form below. My project is due Tue morning May 5th Eastern Standard Time, just in case someone starts reading this on or after that date. Just in case it helps explain the issue, I will also post my listing of error codes from my VB project, and they all are centered around my form1 (which is the form that I'm trying to set up the transfer through of the form totals). I also see that I can post attachments so in case it will help I'm going to post my project in the attachment too.
Error Codes: Error1Event 'Load' cannot be found. Error2Handles clause requires a WithEvents variable defined in the containing type or one of its base types.
using one form information to be transferred to a second form the code becomes invalid after an validation error has arisen from the first form (ie no adult passengers was selected and the error message was displayed) when corrected the information to be transferred become incorrect as the information is transferred without the correction. [code]
I am working on a project that has the user building scrapbook pages through several different forms. When the user selects something a presses a button I have the information about the selection load to a list box which is on a CheckoutForm. One of the options I have is for the user to save what they have made (this includes the information in the list boxes) and return to a previous form to build another page. I have been trying to use the Me.Close() but it does not save the information and using Me.Hide() displays the wrong elements on the forms.
I have a main form and I've created another small form.In the main form I show the small form when they click a button, like this:
Button_Click Function Private Sub AddButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) _ Handles AddButton.Click
[code]....
then the LicenseNewForm appears. The problem the I stumble upon is how I get the information from the license form to the main form when they click a button in the license form or close the license form. The information is more then just a simple input, so I can't use a InputBox call because the license form has 3 comboboxes and a textbox to get the input from the user and then I need to send that input to the main form.

I created a VBA project in Excel. I would like to figure out how to transfer the data back in forth to make a more presentable and user-friendly program in VB Studio.Basically, I need my form in VB to input data to into an excel �workbook.data�, where the calculations are preformed. Then I need to copy the finished excel data cells �workbook.results� and paste them into an end result form in VB. I have tried looking at threads and cannot come up with a solution. There is no data saved each time the program runs, so I don't have a database.
I have a program that uses two forms. The program opens to the Main form, and the user can navigate to the other form from the Main form through use of a button. Here's the way I've currently written it: When the Main form loads, it declares and instantiates the other form during the load procedure. When the user presses a button, the second form is displayed by means of the ShowDialog method. On the second form, there is a Return to Main Screen button which closes the second form, bringing the user back to the Main form.
So, here's the structure of the code:
Code: Public Class frmMainForm
Dim frmSecondForm As New SecondForm
Private Sub btnSecondForm_Click(blah, blah, blah) Handles blah, blah, blah
[CODE]...
Here's my reasoning: Originally, I wrote the code so that a new instance of the second form was created every time the button was pressed. The problem was that whatever data was displayed on the second form, previously, was lost when the user returned to it a second time. Since the user would be switching back and forth between these forms, frequently, I needed that data to persist.
What is the best practice for accomplishing this:
1) Declare and instantiate the second form on program start, as I have done, and use the button simply to show the form?
2) Declare and instantiate the second form each time the button is pressed but maintain the variables on the Main form and pass them ByRef to a custom constructor for the second form? Is this even possible?
Is there a better way to make a form with multiple buttons opening different things than having a form that has lots group boxes for each tab. So in the begining each box will be invisible and when you click the button the corresponding group box will become visible. Is there any other way?It will be like a background image and it'll have buttons that will mask it with invisible buttons. when the button is clicked it will open the corresponding group box.
I have multiple forms and have multiple declarations that I need for all the forms, is there a better way than declaring them each time on each form? Can a .dll do this, if so does it require the .dll to be a seperate file than the final .exe file. Or is there someway to reference the variables on other forms?
If I make the following array in a push button event and I want to put those array variables in a class array. How do I do that? I am just beginning to learn about classes in vb.net but I am having problems using classes and arrays.Is there any good tutorials on that subject.

I am trying to get information from form A to be used in form B. It's just that when I go into form B's load event, it can't find progressbar1 from form A.
I made up Form where you need to fill in information like Name, Surename and Group. And when I press Next (button) I want it to check first if all information is given and in case its not, then you cant go to the next form before filling all information.
i have a form that I need to do two separate functions, however about 95% of the code is the same it's just that last 5% so I don't want to create two forms. What I would like to do is when I click on a button to open the form pass it a variable or something so I can determine which of the two buttons were used to open the form.
Basically if Button1 is clicked do this if button2 was clicked do that...
Therefore that code above works perfectly as both of them saves information to the Customers table and waitingforApproval.The problem is here:When I open form2 which recieves information from WaitinforApproval database table(and I see it getting it from there as tableadapter works), I want to save the received information to the customers.So I have two data sets in here. Just like above So here I have created a button called confirm/save the data to customers. Hence I put this code in confirm button: Form 2 code
And the current dataset set for this form is �waitingforApproval.So it doesn�t save the received information from waitingforApproval into the customers�
im writing a program for my vegetarian girlfriend that does two things from the main menu. 1: add foods with attributes like name, iron content, protein, sodium etc. 2: use the foods that have already been stored and use them to make a balanced meal. What im having trouble with is, how do i save the attributes when storing the foods ? i have knowledge with c++ so i understand how classes work and was wondering if there is something similar in Visual Basic.
I wrote the below code for my final project and I need to pass the array players to the next form that I open called Game I don't seem to be able to make heads or tales of what I have read so far. I will just change where the team is loaded from but I want to do it this way.

At the moment I am stuck with a problem of it telling me it cannot access the text box as it was created on another thread. Does anyone know what I can do with this error? I have tried using invoke statements but it does not seam to work. [code]...
i have two forms and two database tables in sql. my problem is that, in one form(form1) i can save information to another form (form2) but in form2 can't able to resend data back to form1.
Am using dataAdapters and dataSet to load the data into application.
Having been thinking about this issue but doesn't solve it. i mean shall i use select query or what?
In form2, i don't want to insert new information rather all i want is to resend the loaded data from form1 back to it.
