I have 3 forms, the form one is an intro, form 2 loads a user and form 3 displays a user. i use the streamread / writer to load values on form 2, then when successful it loads form 3 and the vaules are transferred perfectly, now to save time i changed the start up form from form1 to form2 (saves having to skip every time). so after having all the code load and transfer i wanted to see it in action and then the issues started.

I have a datarepeater with a textbox that shows a row id in a sql server, for each instance of the datarepeater there's a button on the datarepeater that I'd like to have the user click, and that would send the text from the textbox on that row to another form, possibly just to a textbox on that other form. anyone know the code that would accomplish this? i've been looking all around but no luck, (i did have luck with the item_cloned solution for combobox's in datarepeaters tho..
View 1 RepliesI have a Windows Form Application that has a few TextBoxes, Buttons, and a couple of ListViews. One of the TextBoxes takes an entry (usually by a barcode scanner or the user can type text and hit the TAB character) and then that searches through some data structures and if found it modifies the color on a row in one of the ListViews and adds a row to the other ListView. What I want to be able to do is to put the focus back on the Textbox that takes the input from the barcode reader.The problem I'm having is that the TextBox doesn't always get focus back after a scan. Sometimes after a scan it looks like the focus is on one of the splitContainers. I can manually take the mouse and put the focus back on the TextBox, but that would be kind of inconvienient for the user. What I would like would be for the user to be able to scan (which enters text into the textbox and then TABS out). The TextBox's Leave Event fires and runs the code that manipulates the ListView's and then at the end the leave event code clears the textbox with TextBox1.Text = "" and then calls TextBox1.Focus()
I've tried using TextBox1.Select() and/or TextBox1.Focus() and neither one works. I even put in a Apllication.doEvents() so that any pending action that might cause focus to change will happen before I call the Focus() or Select() code.My guess is that maybe it has to do with some race condition on actions that pull focus away, but how can I keep focus on the text field and still allow the user to use the mouse to press the EXIT or SAVE buttons or even click on an item in one of the ListViews (which doesn't do anything right now).
I do have a check in the TextBox.leave event that checks for empty values using

I'm upgrading a project from VB6 to VB2008.I have a routine that clears a combo box, named 'cmbDataTable' which could be on any form. I pass the form and the combo box is cleared.
[code]...
I assumed it would be the same in VB2008 but I get the error.'cmbDataTable' is not a menber of 'System.Windows.Forms.Form'I am working my way through the project, first updating the global procedures - this is one - I haven't written the calls so cmbDataTable doesn't yet exist.
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 a listview with process that are running. my goal is to pass the "path" of the process to a text box when someone clicks on a selection.but my code isnt working correctly, this is what I have:
Private Sub lvwProcBox_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lvwProcBox.SelectedIndexChanged
Dim pID As Integer = Int32.Parse(lvwProcBox.SelectedItems(0).SubItems(1).ToString)
Dim proc As System.Diagnostics.Process = Process.GetProcessById(pID)

and of course the text boxes path changes to a different path if a different selection is made?

I am using following code to connect to my database.
Dim conStr As String = "Data Source=.SQLEXPRESS; ![enter image description here][1]
AttachDbFilename=|DataDirectory|dbTest.mdf;
Integrated Security=True;
User Instance=True"
Dim sqlQry As String = "SELECT * FROM [tblTest] WHERE ([Name] = @Name)"
Dim dAdt As New SqlDataAdapter(sqlQry, conStr)
Dim dSet As New DataSet()
Then filling adapter with
dAdt.Fill(dSet, "tblTest")
And then I can use the data the way I want.
My question is: How to pass the value of parameter that user will give through a text box on my webform.
Dim sqlQry As String = "SELECT * FROM [tblTest] <b>WHERE ([Name] = @Name)
I mean how to pass the parameter value to my query?

View 1 RepliesI am trying to pass information to parent form from modal form in vb.net winforms application.
1.) I created a copy of a form and displayed it using following code.
dim f=new frmParent()
f.show()
2.) Depending on conditions a button on frmParent opens a modal child form and asks for some informations. I used following code for that:
dim f = new ChildForm()
f.showDialog()
Both code works fine. When user press saves in child form i need to close childForm and use the user types values in parent form. I know how to close the childform but not sure how to pass info from childform to parent form.
in my form, i have a textbox in which its visible property is set to false. this textbox is bound to my table's primary key column.
whenever i try to add a new record, it automatically generates a value and i can see that when the visible property is set to true. now when i set it to false and do a messagebox.show(textbox.text), it shows no value. so i set the visible to true and then the messagebox does show a value.
i don't want this textbox shown in my form but i need to get the value from the textbox when the primary key value is generated.
how can i do this without showing the textbox?

I have a 2nd form that is minimized to the taskbar, I can click on the tab and the form opens and shows all of the data fine, but
From the main form, I am maximizing the second form and trying to pass a value to a toolstrip textbox on the second form then press a button on the toolstrip from the second form, I can get this to work fine, but where I am having a problem is
The button searches through a treeview, when I step through my code, I can see the value that I am passing, my code does execute, but the treeview is showing no nodes(but they are really there). At the begining of the code, I put a message box to give me a count of the nodes in the treeview, it shows 0, but I can see all 10000+ nodes. What the textbox is on the toolstrip is a search box. When the form is maximized, I can enter whatever and it finds it with no problems, but if I pass a value it doesnt find anything because the treeview is saying there are no nodes when there is.
I have simple app with Form1, Form2 and Form3. Form 2 is being opened with button form Form1. Form3 is being opened with button from Form2. Form1 is startup form. I can call any public sub on Form1 from Form2,(using on Form2 command "form1.mypublicsubname". If I try to call public sub on Form2 from Form3 nothing happens. If I put simple Msgbox "Hello" in public sub on Form2 and I call it from Form3 I do get Msgbox saying Hello. If I put in same public sub something like me.mydatagrid.refresh nothing happens. Also if I try calling me.mydatatableadapter.fill nothing happens. I guess it has something to do with invoke but I just don't know where to start.

View 11 RepliesI have a form with 2 dateTimePickers and a SHOW button which gets data from an sql server database and displays it in a DataGridView. this works ok. I also have an EDIT button which brings up another form with textbox and comboBox controls displaying this one record. I want to be able to click in the DataGridView to select a Name and then click on the EDIT button to bring up the selected record. I don't know how to pass the ID as a parameter to this second form. Apart from that the EDIT button works, in the sense that I hard coded the ID (32 or 35 etc.) and it brings up the appropriate record. But how do i pass the selected ID. [Code]

I am using Visual Basic 2008 for this assignment. I have a project that I am working on and I need to be able to use form variables across the entire project.
I have looked on other forums but no definitive answers.iI have declared variables as such Public StrV21true As String and "Public StrV21False As String
Now apon assigning a string to the variable with an If Then Else Command, I go to the next form expecting that the assigned variable will be available for use in this second form but to my dismay it tells me that the variable has not been declared and will not even show up in Intellesence. Like I said before from research on the net I am using the public class in Form 1 to hold the variables and am kind of expecting the public class variables to be available through all the forms in the project. I would really like to know how to do this so as I can finish my project for class.
I've got a form in my MDI container. Lets call it Form1. I now want to show a dialog box (Form2) and pass the primary key from Form1 to Form2. Do i create a public function on Form2 called SetMe() or Do I create a public on Form1 And read from it? From a best Practice point of view, How would you go about it?
