Accessing Value In Textbox From The Different Form In Vb2008
Sep 29, 2011
I'm using visual basic 2008. I am done coding the CRUD... but i want it to have confirmation first. Then, i tried using panel, it works. but, my interface looks not organize. Is it possible to access the values in the text boxes from the other form?
For example: the client's information text box are on the form1 and once add button is click, the confirmation box will pop out. and the pop out box is in the form2. Is it possible to access the form1 text boxes from the form2?

I am fairly new to VB .Net and have ran into an issue when working with multiple threads using BackgroundWorker.In the new thread that is created I need to access TextBox1.Text to know what the user's input was.For example:When the 'OK' button is clicked BackgroundWorker1.RunWorkerAsync starts a new Thread.
Private Sub OkButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OkButton.Click
'We cannot start more then one calculation at a single time
OkButton.Enabled = False[code]....
I know how to use Delegates and Invoke to change the value of a Textbox, but I cannot figure out how to simply access the text from a Textbox.

I have this code
Dim replace As String = System.DateTime.Now.AddDays(7).ToString("yyyy-MM-dd")
What I'm trying to do is
Dim replace As String = textbox1.text.AddDays(7).ToString("yyyy-MM-dd")
is there a way to use that add days from a text or string value already?

So I'm attempting to get three variable to print in a string, but I can't figure out how to make the Concat or Join commands to work properly. I've tried assigning the strings to a defined string variable and then "concatting" that and trying to do it in one big line. I keep getting an error either way. Here's what I have so far:
Str1 = PaymentNumInteger
Str2 = NewBalanceDecimal.ToString("C")
Str3 = MonthlyIntPayDecimal.ToString("C")

I have a program I've been working on for some time now and I'd like to try to streamline it somewhat. I have a main menu form that has a split panel, in the left panel is a treeview that displays forms you can open and when one is selected, it opens in a child window in the right panel. Each time I open form I called DWNForm, it does a series of dataset loads which are the populating items for a series of listviews.
What I would like to do is have these datasets load once during the mainMenu load and then have the DWNForm be able to access the datasets once it is called from the treeview selection.

im trying to access a richtextbox from another class and thread then the ui and i cant seem to get it working. I currently have the sub thats handling the the work inside of a public class and its a sharedsub, im going to be calling it from several different classes and threads but again i cant seem to get it working. the code looks like this. Public Class SharedSubs
[code]...
i would be calling sub using SharedSubs.Console("stringstring") when this is called from the ui thread it works fine but when its called from anyother thread or class its does nothing,ive confirmed it going thru this code but its not displaying anything in the textbox and its not thru an exception due to delegates either which i figured it would.

I have a form where I open an Access database with 3 tables. I have defined datasets and dataviews for these three tables in the main form. I want to open a new form and access and update the tables using the dataviews I've already defined. When I try to access a record from the dataview using the new form, it's not defined. Can I pass the data between forms or do I need to redefine it in the new form? This is the first time I've tried to use multiple forms.

I am using Visual Basic Pro 2008 SP1. I am currently working on a windows application form project and everything was fine until recently when I try to add a new item (does not matter a new form or control), the whole program is frozen up. If I look at the task manager, the "devenv.exe" process memory usage keeps increasing until FatalErrorOutOfMemmory. I can run build, debug without any error. I can publish the project and run the program without any problem too. I have tried to open a new project and I can add a new form or control without any problem. I wonder if there is something in the project causing this problem and where I should start to troubleshoot it.

Basically what I need to do is change a textbox on Form1 (AKA mainwin) from Form2 (AKA loginwin) using data that is inputted into Form2. I've done this before with applications by declaring Form1 in Form2, but this time I just get a NullReferenceException error. Here's the code I'm currently using for Form2. Maybe someone here can tell me why it's not working. [Code] I can't figure out why it's not working. I've used this same method before and it always worked.

I have a datagridview on a form and this shows up my list of suppliers. I have a textbox which when i click shows up the supplier list and from there when i double click on a row, the supplier's name is shown in the textbox. The thing is i have to do same on the same page for search purposes which got its own textbox. But the cell double-click event already contains code that will display it in some other textbox like i mentioned previously. What i thought is to make another form with a datagridview. So this datagridview will be used to display the supplier's name in search textbox. But what if i have to access this form several times. Do i have to create several forms everytime?
