Notify A Form Sub From Module?
Nov 21, 2010
I am writing a program in VB2010 Express that handles serial port communication. All subs and functions that handle writing to, and reading from the serial port are in a module. These subs and functions are typically called from a form, e.g. by pressing a button. The command is then sent to a device attached to the serial port, and this device replies with a number of bytes as a result. A 'ReceivedDataHandler' is used to handle the serialport.datareceived event. [code]....

I want the form to hide when I click on the minimize button, then the notify icon will show up on the system tray. I have this piece of code:
(ntfLibSMS is the name of my notify icon)
Private Sub LibSMS_Resize(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Resize

I am making an application which has a form that I have set a notify icon for, I load this form at startup and then hide it. Then I have another form that the user can load (from the notify icon) which loads and runs a sub on another thread using the following
Dim d As New MyDeligate(AddressOf ProcessReminders)
d.BeginInvoke(AddressOf RemindersComplete, Nothing)
When this is executed another notifyicon appears, and then when the form closes it stays. I also notice that the memory usage remains higher than when the form loads. How do I prevent this, I am not sure but I believe that by creating the new thread it recreates the initial form and then it is not destroyed.

Simply saying I've added an Notify Icon to my project and then added context menu showing up when the left mouse button is pressed. The problem is that with the context menu some blank form is showing in the taskbar. There is no such form within the project.Does anyone know why it may be happening or how to get rid of the effect? I might add that I have other context menu attached for mouse right click button and it works fine, no blank forms and such showing on the taskbar it's just the left mouse button that works that way.Here is the code that I am using to show the menu:(the visible state to false is necessary for the other menus not to pop up with the one i want... unless anyone knows better method)
Private Sub NotifyIcon_Click(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles NotifyIcon.Click
If e.Button = MouseButtons.Right Then

I have set up a notify icon for my form. I want to make it so that when the user clicks the close button that it doesn't close the form it just takes it to shows the notify icon. They can exit the program from the notify icon. Can someone tell me how to keep it running?

I'm trying to figure out the best way to reference a control on a form from within a module. Unfortunately the form is just an instance, so it's not as easy as calling form.control...
Dim ChildForm As New frmSearch
' Make it a child of this MDI form before showing it. '
ChildForm.MdiParent = Me
ChildForm.Show()
That form has an option for printing, which calls another form where certain options are chosen. The print form in turn calls a function in a module, which tries to reference back to the origional form.
childform as new frmSearch -> frmPrintForm -> sub okToPrint (in module Print)
okToPrint tries to reference a listview on frmSearch, but can't find it.
For Each itmX In frmSearch.lstResults.Items
So the solutions I can think of off the top of my head are:
1. Somehow divine which form is the caller of frmPrintForm
2. Pass ChildForm to the frmPrintForm as a variable to be passed on to module Print..
3. Use frmSearch directly instead of using an instance of it.
Number 1 would be my preference, as I don't want to have to pass forms around like that.

How can I edit my a form through a module? I am using this code in the module.
Here is where I get an error: Private Sub ExtendedWebBrowser_NewWindowExtended(ByVal sender As Object, ByVal e As WebBrowserNewWindowExtendedEventArgs) Handles Me.NewWindowExtended Button1.Text = "New window event just triggered!"End Sub
The code editor will not recognize when I type Form1, and I obtain the following error when I manually type it:form1' is not declared.I sense there is something I can do here which is very easy to fix this, but I have not worked much with Classes before.

How do I do something like this.[code]...
This is inside the Module separate from Form1 class as you can see right off the bat it's not a class and there is no reference to Form1.. how do I access Form1 without passing reference to make factory modules work like this.

i've created a Sub in a Form.
I've created another Sub in a module.
I call the Sub in the module from the form, passing the form into the Sub defined in the module.
Then i add an Handler to an istance of a control (for example mousemove) and i want to give to this handler the execution of the Sub defined in the form.
Example.
Class form1
Sub Form1Sub()
ModuleSub(me)
[Code]....
The problem is that i don't know hot to call the Sub defined in the form, in the Sub handler using the istance of the form passed in the Sub paramenter in the module...

I have a main form (frmPos) and through a module (modTransaction) I open and close several other forms. This works flawlessly. However, when the function on the module is finalized, I want to clear the main (open) form. Therefore, I made a public sub (clearForm) on the main form and when I call this from the main form it works.

I have a situation where I need to display a Modal Window from a vb.net module and feed the contents to that modal form from the module.I am showing the form , feeding data to it from a class module and trapping the events in it using a timer control from the module.It works fine with Show() method but it doesn't with ShowDialog().If I used ShowDialog() then I was not able to continue with the code followed by it and not able to update any contents in the modal form.
I am using VS2003 version.Is there any workaround to this?

I have a form called form1 which has a thread that runs a sub from a module.[code]...
Well from the module, there's a part where I have to update controls on the form1. Whenever I try doing it, it updates the value, but not the design. For example I write a delegate which makes label1.text = "111", while debugging, label1.text becomes 111, but it does not show it updated on the form design, it just stays at its default value.

I'm writing a program in vb.net 2003 and have come up with a problem.
I have a sub SettingsSave() in a module.
Public Sub SettingsSave()
Dim frmSaveSettings As New frmSettings
MsgBox frmSaveSettings.txtName.Value 'for testing purposes
SaveSetting("MyApp", "configs", "Name",frmSaveSettings.txtName.Value)
SaveSetting("MyApp", "configs", "Pass",frmSaveSettings.txtPass.Value)
End Sub
I have a form frmSettings, which has a button btnSave. When the button is clicked, SettingsSave() is called.The problem is, if btnSave is clicked, then either of the two textbox values are changed, then btnSave is clicked again, the SettingsSave() sub still returns the 'old' values (from the first time the save button was clicked).How do I clear the old values from memory? I've tried adding frmSaveSettings = Nothing, and frmSaveSettings.Close at the end of the sub SettingsSave().
