I have a datagridview where i add rows using array like this:
Dim srow() As String = {getIDprodus(cmbprodus.Text), cmbprodus.Text, getprodusforma(cmbprodus.Text), txtcantitate.Text}
griddetalii.Rows.Add(srow)
Next, i need to let user to modify the added row. So when user selects a row and press EDIT, a new form is popped out using this code:
Dim i = griddetalii.CurrentRow.Index
frmdetaliiiesire.cmbprodus.Text = griddetalii.Item(0, i).Value
frmdetaliiiesire.txtcantitate.Text = griddetalii.Item(1, i).Value

In textbox1 i have put the index of the current row selected in grid The problem is when i push OK, the applications crashes and i receive an error: INDEX WAS OUT OF RANGE
If the users changes the values from the same form, it's works. But changing them from another form crashes the applications
I update a Form's Title from within the form, but it doesn't update. Any idea how to "Refresh" it so that the update displays?
View 2 RepliesI'm not sure exactly how to describe this. In VB6, there was a Timer command. I could create a variable of type Timer and loop until the current value for Timer exceeded the initial plus a given amount of time. This allowed me to update form variables while the timing loop was executing. How can I do something similar in .NET?
Here is a sample of the VB6 code:
Code:
Dim StartTimer As Double
StartTimer = Timer
Do

After making the changes or adding a record I use invoke childmethod from my toolbar to call these subs. The first table updates and adds, but the second does not. I have set all of my textboxes databindings and double checked them. I get no error, but it does not update the second table. What am I doing wrong?
Public Sub AddRecord()
'Clear out the input data fields on a new Add.

When I use
Me.Close()
Form1.Show()
It closes the whole app.
How would I change it so that it only closes the current form while opening a new one? EDIT: I put [Not Resolved] Because I accidently pressed the resolved thing
My project will end up with several forms to be filled out. Once a form is completed, a button can be pressed revealing the next form or previous form if something is going to be changed. I've been using Me.Hide() so that the users screen doesn't get to cramped.
I'd like a few things to happen. If an input from one form changes a value on another I'd like it to update automatically, I figure some event on button_click or form_load. My problem is that different things work depending on how I open or hide a form. I would also like the forms that have been Me.Hide() to retain the value in the textboxes. Let me show you from a practice vb project so that you don't have to dig through the larger code.
Public Class Form1
Public Shared Info1, Xcord, Ycord As Double
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[code]....
1) If I don't use "Public Shared", TextBox1.Text does not update.
2) If I reopen Form1 with the "Dim First As New Form1" method it seems to refresh the Form1_Load. If I use My.Forms.Form1.Show() it does not. Another side effect is that clicking the close button on the ControlBox ends debugging when using "Dim First As New Form1" and does not when using My.Forms.Form1.Show(). Wierd. I've set ControlBox to False on Form2 and Form3, otherwise the program remains running in the task manager. I've read other solutions to that problem, but my solution seems to work for me so far.
3) Xcord and Ycord are my attempts to have the other forms open on top of the first form. My problem now is that I have them set to CenterParent and they open where the first form used to be. If I move Form1, Form2 and 3 open where I've left them instead of centered on Form1, maybe. Form1 is set to WindowsDefaultLocation. My new plan is to set to manual and have Xcord and Ycord update and then offset based on form size. So far I haven't implemented that code.
4) Me.Close() ends the program.
Public Class Form2
Public Info2 As Double
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim First As New Form1 'Done so that Form1.Info1 works
[code]....
I'd like a consistent method that represents good programming practice. My understanding is that Public Shared is frowned upon. I'm also wandering if Me.Hide() is the right choice. I've also played around with .ShowDialog() which didn't work?
I am sorry to keep bothering you about this damn DataGridView control ... As you might have noticed I am having a hard time with the DataGridView control ... My latest problem has to do with updating the data base file (Access) through a DataGridView control .
Up to now I have managed to successfully edit an entry in the DataGridView control and moreover to successfully update the data base file itself .
The above form and its code work fine . The problem starts when I am trying to run the code of the Update button from another form .
You see , I have another form , through which I change the contents of some of the cells in the DataGridView control (back in Form1) . What I want next is to simply update the data base file itself , just like I was doing with the button in the first form , after I manually changed the cell in the DataGridView control .Thus , on the second form I have a button with this code :
Form1.Button1_Click(Nothing, Nothing) (of course the Click event is declared public)I have also tried :
Form1.Button1.PerformClick()
but still nothing ...Although Form2 successfully changes the cells back in Form1 , the data base file itself does not get updated ...If I manually press the Update button in Form1 I once again successfully update the data base file , but I want to do the whole thing by calling the Update button from Form2 .
why I need to instantiate a form instead of form.show?

I have a dual monitor setup on my computer. My program has multiple forms. I've designed the program to check which monitor the main form is currently on and to open the secondary forms on the current monitor. When the main form is on the primary monitor the secondary forms open as FormWindowState.Normal which is the design-time setting for the secondary forms. If the main form is on the secondary monitor and I click to open a secondary form then the secondary form is to be displayed as FormWindowState.Maximised.
[Code]...
So I moved the Form.Show line to after the Form.WindowState line. This works fine when the Form.Show process is very quick. The problem is that one of the secondary forms downloads some information from the internet so it takes about a second to finish the Form_Load process. When I had Form.Show first the form would not appear on screen until the Form_Load process is complete, so the delay was in the form appearing at all which is how I prefer it. With Form.Show last the form appears on screen immediately but appears mostly blank and unresponsive until the Form_Load process completes.
I would prefer that the form not appear at all until the Form_Load process is complete but I would like it to appear in an already Maximised state. Is this achieveable? It doesn't seem that complicated but I just can't figure it out.
[code] I can't show the form 2 when i use TAB.tabindex already set into 1.
View 6 RepliesMy mate & Myself are currently building a IRC Client, a problem we have come across is when opening a chatroom the form Freezes for example.
We are currently using arrays so we can open multiple chat rooms and at this current time to open a chat room we use
Channels(ChatIndex).Show()
The form opens but freezes.
I have also tried using
Channels(ChatIndex).ShowDialog()
Application.DoEvents()
Using the above code, the form does not freeze but appears we can not access any of the controls such as (RTB)
What would be causing the form to freeze on .show(), Has anyone else had any similar issues?
