Hello !
I'm using vb.net 2013.I have 3 forms : Form1, Form2, Form3
On form1 I have a button . When this button is pressed , the form2 is open.The code inside the click event is :
Dim dlg1 As New Form2
dlg1.Show(Me)
Inside From2 I have a TextBox (Txt1) and a button .When this button is clicked the Form3 is open.The code inside the click event is :
Dim dlg2 As New Form3
dlg2.Show(Me)
Inside form3 I have a button that I use to set a value in the textbox (txt1) on Form2. I use this code :
Form2.txt1.Text="123"
The problem is that after I press the button on form3 , the textbox on form2 is empty , no value is set.
What can I do ?
Thank you !

Show your exact code. It's impossible to tell what's wrong from those tiny snippets. And put the code between <pre> </pre> tags to preserve the formatting.
The difficult we do right away...
...the impossible takes slightly longer.

The problem is because of incorrect referencing.
Consider this:
You are creating an Instance of Form2 as dlg1 and then trying to set value inside Form2 (which isn't loaded). This creates a new instance of Form2 and you see the blank values.
Basically what you are trying to do is to return value from custom designed dialog forms - right !
Try this:
Declare a Public Variable in Form1 to hold Form2 value
Public Form2VAL as string
On Form1 Button Click write:
Dim dlg1 as new Form2
dlg1.showdialog
msgbox (Form2Val)
Form2Val = nothing
On Form2 Button Click write:
Form1.Form2Val = "SomeValue"
Me.close
Similarly for Form3, Declare a Public Variable in Form2 to hold Form3 value
Public Form3VAL as string
On Form2 Button Click write
Dim dlg2 as new Form3
dlg2.showdialog
msgbox (Form3Val)
Form3Val = nothing
On Form3 Button Click write:
Form2.Form3Val = "SomeValue"
Me.close

Looking at these results [^] and your comments you are trying to use a demonstration versions of a retired tool set, possibly in VB6, a dead language. You may have an unresolvable problem doing that.

Hello Guys.
I have a VBScript and want to copy a file. I want to make sure it finishes successfully.
If the destination-file is set to "read-only" there occures a Runtime Error '800A0046 - Permition denied'.
What I want: I dont want to get the Script-Host error message but instead my own. Therefore I need the error number ( the error code 800A0046 does not work ) so that I can use
On Error Resume Next
IF (Err.Number > 0) THEN
IF (Err.Number = 32755) THEN
...............
as I did it here to check if the user pressed cancel in a open-dialog box.
Since I'm very new to VBScript programming , I don't have any idea where I can look for a solution to problems like this one. So I hope to find help here. I googled a while and also searched in the MSDN but found nothing.
Thank you very much.

Set oFS = FSO.GetFile("d:\test\o2\test.png")
IF oFS.Attributes AND F_ATTR_RONLY
THEN

FSO.CopyFile "d:\test\o1\test.png", "d:\test\o2\"

Can someone please guide me through this?
In this program you will create a Windows Form application that will calculate and display the money made by a drive-in movie theater each night. The movie theater has two types of nights. A "Regular" night is where each person in a guest car has to buy a ticket, and each ticket costs $10. A "Car" night is a special promotion where there is one price per car of $15, no matter how many guests are in the car.
In addition to the cost of entry (either Regular or Car), the theater sells popcorn and candy but the price of the items depends on the type of night. On a Regular night popcorn costs $1.50 per box and on a special Car night popcorn costs $2.00 per box. On a Regular night candy cost $2.25 per candy box, while on a special Car night candy cost $3.00 per box.
On any night, the maximum number of cars allowed in is 500 and the maximum number of individual tickets is 3,000; the theater can produce 4,500 bags of popcorn each night and has 4,000 candy items.
Once the total sales are calculated, the program will display a summary message with the type of night, the total number of cars, the total ticket sales, the total popcorn sales, the total candy sales, and the total sales amount.

Looks reasonable to me, and you didn't receive any harsh comments yet.
If it does what the assignment states (and compiles), then it's a go

Good stuff.
To add elegance use a StringBuilder for your message.
Normally you would get ragged on for posting an assignment (and was roundly ignored), posting the solution got you the upvote

Can you explain further? Can you site your code? Or even tell us what are those two arguments you'll use?

You cannot 'compile' an Excel file into anything, it is purely data. You can use protected cells and passwords on the files as necessary.
