View 1 Repliesi have a MDI application with parent and childforms.
i have a global timer in a module that makes a com search and writes the result to a parentform status strip label.
the problem is that the label do not change.
i have tried the following:
1) on timer.elapsed
parentForm.statusstriplabel.text =...
2) to create a delegate and invoke a parent form function
3) to create and raise an event
although all 3 seened to run the label didn't changed.
the timer was created in a different module than the parentform class for many reasons.
one of them is because i want to access the timer.start , timer.stop from all the childforms
when i tried a local timer to paretform worked perfect but i couidnt start and stop it from the childs

View 5 RepliesI am in the process of upgrading a VB6 Project to Vb.net. My problem is that when I open a child form in my project from within the Parent form a new instance of the Parent form is created. The code is fairly simple:
frmnewContract.MdiParent = Me
frmnewContract.Show()
my problem is that i have an MDI Parent form. it has lots of child forms. on my MDI Form i have the toolbar buttons Add, Delete and Save.all or most of the child forms, i created a custom public procedure Sub AddNew, Sub Delete and Sub Save.what i'm trying to do is when i click the AddNew in the MDI Form, it will run the custom public Sub AddNew of the currently ActiveMDIForm. i have tried...
DirectCast(Me.ActiveMdiChild, Form2.AddNew()
but i'm getting an error "Unable to cast object of type 'Form1' to type 'Form2'" if the currently ActiveMDIChild is not Form2.

Just had a small doubt.Say i use something like this
vb Dim ownr as New Form1Dim Dlg as New Form2ownr.Showdlg.showdialog(ownr)
how should i call an public function of form1 in the form2 if form1 is owner of form2, and also if form1 is not the owner of form2 should i use FormName.FunctionName in both the cases.
I have two forms. Form A and Form B. Form A has a datagrid that is populated from a SQL Database Table query. When a button is pressed Form B is launched that allows you to add a record to the database table. I need for the datagrid to be refreshed and show the newly added record when I close form B and go back to the parent.

I need to know the proper way, or maybe I should say, the different ways to call another form from a parent or preceding form. I am currently using ex: formname.showdialog() to call my next form, but I am uncertain if I should be using that in every situation. [code] Whats the difference between these different methods? (ex: .showdialog() , .show() )I tried both of these to open a temporary form to retrieve a persons name from a database, so as the users progresses through my training program they can keep track of their scores.But, I also call other forms as I branch through my program, from the main page, to a secondary page, to a testing page, to a results page and then back to the secondary page

I have a class inhert ToolStripButton. it builds a new toolstrip button. the button will be added to the toolstrip which is on main form.
I will need call function in the main form. what's the right way to do this?
now, I pass the main form when create the class. but I guess the right way is to raise the event in main form.
but, how about the properties in main form?
if I raise the event, will it run the event first, then go to the next line of the class? or, just raise event, then go to the next line in the class immediately?
I am trying to create a project in VB 2010 like I have in VB6. In VB6 I have a parent form which opens a child form. The child form displays calls (customers) on a spread sheet control that are on hold. The user selects the call in the child form, it calls a sub in the parent form passing a record number to identify the customer. The parent form then "pulls" up the call and and connects the user to the caller with all of the customers information.So, I haven't done this in VB NET and I have searched to see if this would be done the same way in .NET as it was in VB6, but I haven't found much decisive information. Is a parent/child form the way to do this?

I get an error message which say FrmEmbed is not defined. How can I correct this?
My main form is a tabbed control with 2 tabs. The first tab is has two listview controls which display information about the current machine. The second tab contains a treeview control and two listview controls. This tab recreates the device manager in windows. I created a Machine class to gather the information about the machine that I want to display to the user. When I call the Display() Method from my form's load event everything appears to be fine the first tab's information is displayed in the listview controls.
Here's the kicker, when I click to the device manager tab there's nothing there. The LoadTree() procedure never fires. This code works, I've seen my device tree display a thousand times in the past. When I comment out the call to Machine.Display() my device tree reappears no problem. The code compiles fine no errors. I know the problem has to be in my Machine class but I have no idea what could cause this kind of response. I've never seen a program compile clean and then refuse to fire a procedure call but not produce some kind of runtime error.
This is a challenging one that got me stumped while I was coding today. Suppose I am running the Sub Test1() and Test2() and would like to print out the value of the Shadows method of the instance of the object I am passing in to TestCall() (see below - it is clearer) using the following restrictions:
Can't change the contents of Class A, B, and C
Can't change Sub Test1() and Sub Test2()
TestCall() can't have an if, select case etc. statement that tries to figure out the type

The instructions are as follows:
1. Write a Visual Basic Console Application.Inside the main procedure call a function procedure to input and return a value for a double variable called x, the width of a right triangle.Inside the main procedure call the same function procedure a second time to get a value for a double variable called y, the height of a right triangle.
2. From the main procedure call a function procedure which calculates and returns a value for the hypotenuse equal to the square root of (x squared + y squared).You will have to pass the values of x and y to this function procedure.The procedure should calculate and return a double type value.The value that is returned by this function procedure should be equal to the square root of (x squared + y squared).
3. Also from the main procedure call a sub procedure to display the values of x, y, and the hypotenuse.
I connected to the Informix server using RazorSQL, created a stored procedure and tested it, getting the expected answer, so the procedure exists in the database in some form.
I then run the following code:

cmd.CommandType = CommandType.StoredProcedure
