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.
View 2 Repliesi'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 form set up where I want to run the function PopulateGrid on it's Form_Load event. I have initialized the DB connection as follows:
Private Sub Main_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
LoadConfigFile()
cn = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & config("DatabasePath") & ";")
cn.Open()
End Sub
Now, I want to run the PopulateGrid function directly after I connect to the database as shown above. I'm confused as to how I'd use a database query in a module when the database is initialized in my main form. Would simple setting the variable cn to public work?

View 11 RepliesI have a Util module in my VB.NET program that has project-wide methods such as logging and property parsing. The general practice where I work seems to be to call these methods directly without prefixing them with Util. When I was new to VB, it took me a while to figure out where these methods/functions were coming from. As I use my own Util methods now, I can't help thinking that it's a lot clearer and more understandable to add Util. before each method call (you know immediately that it's user-defined but not within the current class, and where to find it), and is hardly even longer. What's the general practice when calling procedures/functions of VB modules? Should we prefix them with the module name or not?

View 3 RepliesThe company I work for has a VB6 project that is using an ACCESS database.The project consists of seperate modules such as Accounts Payable, Payroll, General Ledger, and Inventory.At the current time each module is a seperate project in VB6 and the EXE files are called when needed.In total there are about 1300 forms in the project.We are moving from ACCESS to Sql Server and from VB6 to VB2008.The question that I (we) have is as follows; Should we continue to keep each module seperate and call the EXE's or should we create one large project?What are the pros and cons for each way?Is there something written that explains the advantages of either?

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.
