I am trying to pass a value of a textbox on frmMain to a textbox on frmDepartment. I have tried the following code which I thought would work but it dosen't. I ma a new user to VB and come from a php background where it would have been a simple task of setting a seesion. Can anyone help with this? If you need to see more code, please ask. many thanks
txtDeptCustomer.Text = frmMain.txtCustomerActive.Text
In frmMain, I am getting value like this:
Dim value As Object = UserDataGridView.Rows(e.RowIndex).Cells(0).Value
txtCustomerActive.Text = CType(value, String)
Private Sub btnDepts_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDepts.Click
frmDepartment.Show()
End Sub
Which is showing in frmMain ok.
In frmDepartment I have this code
Private Sub txtDeptCustomer_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtDeptCustomer.TextChanged
'Dim customer As String
txtDeptCustomer.Text = frmMain.txtCustomerActive.Text
End Sub
instead of putting the code within the txtDeptCustomer.TextChanged sub, try putting it within the frmDepartment_load:
Private Sub frmDepartment_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
txtDeptCustomer.Text = frmMain.txtCustomerActive.Text
End Sub
or you could set the frmDepartment text box text on the frmMain button click:
Private Sub btnDepts_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDepts.Click
frmDepartment.txtDeptCustomer.Text = txtCustomerActive.Text
frmDepartment.Show()
End Sub

A noob query I have, is there any way to use a single command to open different forms on different button click events. I have 24 buttons in one form and will use these buttons to open 24 different forms.
So instead of doing it for 24 times as:
Private Sub BtnCh1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnCh1.Click
FormCh1.Show()
End Sub
Private Sub BtnCh2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnCh2.Click
FormCh2.Show()
End Sub
Private Sub BtnCh3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnCh3.Click
FormCh3.Show()
End Sub
Private Sub BtnCh4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnCh4.Click
FormCh4.Show()
End Sub
Can it be done with a single command?
In your form's load event add the forms in a List(Of Form)
Private list As List(Of Form)
Private Sub Me_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Me.Load
list = New List(Of Form)
list.Add(New Form1())
'
'
'
list.Add(New Form24())
End Sub
Set your button's Tag property with the form's index and set them all to use the same click event:
Private Sub btn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn.Click
list(CType(sender, Button).Tag).Show()
End Sub
Attach all the handlers to your method and then branch behaviour based on the Select Case:
Private Sub Button_Click_Handler(sender As Object, e As EventArgs) Handles Button66.Click, Button67.Click, Button68.Click
Dim btn As Button = DirectCast(sender, Button)
Select Case btn.Name
Case Button66.Name
Dim f1 As New Form1
f1.Show()
Case Button67.Name
Dim f2 As New Form2
f2.Show()
Case Button68.Name
Dim f3 As New Form3
f3.Show()
End Select
End Sub
That might have sounded weird so let me explain.
I have a school assignment that has me pulling my hair out. I have to get a collection of 5 facts and have them display to a ListBox using a For Next Loop. The user would use an InputBox to input the facts.
I dont know what to put in the For Next to fetch the string from the InputBox. I'm at my wits end and am falling behind.
Here is what I have so far
Public Class frmWWIIFacts
Private Property RemoveAt As Integer
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub
Private Sub AddFactToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AddFactToolStripMenuItem.Click
Dim intFact As Integer
Dim strInputFact As String
strInputFact = InputBox("Do you want to add a fact?", "Add a fact")
For
Next
strInputFact = InputBox("Do you want to add a fact?", "Add a fact")
End Sub
Private Sub CloseToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CloseToolStripMenuItem.Click
Application.Exit()
End Sub
Private Sub ClearListToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ClearListToolStripMenuItem.Click
lstFacts.Items.Clear()
End Sub
Private Sub RemoveFactToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RemoveFactToolStripMenuItem.Click
End Sub
I've submitted a reddit post requesting some assistance but its gotten me nowhere. https://www.reddit.com/r/learnprogramming/comments/3t614u/vb2015_using_menustrip_to_addremove_items_in_a/
I would love some help on this. Please ask questions if your confused on my method or if you need to know more.
Sounds like you're trying to do this:
Private Sub AddFactToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AddFactToolStripMenuItem.Click
Dim intFact As Integer
Dim strInputFact As String
lstFacts.Items.Clear()
For intFact = 1 To 5
strInputFact = InputBox("Please enter a fact:", "Add a fact")
If Not strInputFact = "" Then
lstFacts.Items.Add(strInputFact)
End If
Next
End Sub

Here is how your form should look like :
And now you need to add the "Time" columns to the datagridview:
And now... follow my steps through the image:
and here is the code :
Public Class Form1
Private Sub Button6_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button6.Click
Table1BindingSource.Rows.Add()
Table1BindingSource.Rows(Table1BindingSource.Rows.Count - 1).Cells(0).Value = TextBox1.Text & Table1BindingSource.Rows.Count
End Sub

I'm trying to add a new row to a DataGridView from FORM 2 but I can not succeed, the code I tried is as follows:
FORM 2:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
FORM1.invoice_items.Rows.Add()
End Sub
Looking like it took time but can not find a solution, someone who can help me with my problem would be nice, Thank You.
Try this
This work only if you use a showdialog.
Form 2 :
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'Pass the value to be added in the datagrid to form 1
Me.DialogResult=Windows.Forms.DialogResult.OK
End Sub
Form 1:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If Form2.ShowDialog = Windows.Forms.DialogResult.OK Then
'Getthe value from form 2
invoice_items.Rows.Add()
End If
End Sub
Using VB.Net (Windows Application)
In the form (called as FirstForm), i am using textbox, add-form Button, search button.
When i click the add-form button, it will give the new form (same as FirstForm)
Code for adding new form
Private Sub btnadd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnadd.Click
Dim SecondForm As New FirstForm
SecondForm.Show()
End Sub
Search Button Code
Private Sub Search_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Search.Click
If FirstForm.Focus = True Then
FirstForm.textbox1.Text = gridview1.Rows(crRow).Cells("code").Value.ToString().Trim()
Else
Dim SecondForm As New FirstForm
SecondForm.textbox1.Text = gridview1.Rows(crRow).Cells("code").Value.ToString().Trim()
End If
End Sub
The above code is working, but If i am in second Form when i click the search button and selected the value, then the value is appearing in the FirstForm textbox, it is not appearing in the SecondForm textbox.
If SecondForm is showing, the selected Value should appear in the SecondForm textbox not in the FirstForm Textbox.
How to solve this issue.
Need Vb.net code Help
Use Me - Reference variable which hold ref. of current form.
Dim frm As FirstForm
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
If IsNothing(frm) OrElse frm.IsDisposed Then
frm = New FirstForm
End If
frm.Show()
End Sub
Private Sub Button2_Click(sender As System.Object, e As System.EventArgs) Handles Button2.Click
Me.textbox1.Text = gridview1.Rows(crRow).Cells("code").Value.ToString().Trim()
End Sub
Using "me" will not solve the problem?? why are you referring to the form in a static way?
Private Sub Search_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Search.Click
textbox1.Text = gridview1.Rows(crRow).Cells("code").Value.ToString().Trim()
End Sub
