Reload Form And Reset All Variables And Arrays
Mar 22, 2008
My program is only one form, at a certain point I want the form to reload, and have all the variables and arrays be reset? I am able to to reload the form by:
Dim frm As Form
frm = New frmMain
frm.Show()
But the original form still stays open? My program is a version of blackjack. when who won or lost is figured out i want all the cards to clear (held in an array of picture boxes) I have random numbers generated (also put into an array) each random number then finds the image of the card it belongs too and then places it into the array of picture boxes. How to reset the arrays so I thought maybe trying to just reload the form would work?

SI have a form and on submit I need the following variables stored in array.
Dim OrderName, OrderNumber, OrderSize, OrderQuantity, OrderAddOn, OrderEachPrice, OrderTotal As String
So pretty much its an order a customer will be making and every time a new order is placed, a new array will be made.
Example:
OrderName = TextBox1.Text was Sean
OrderNumber = TextBox2.Text was 123456
OrderSize = TextBox3.Text was Large
OrderQuantity = TextBox4.Text was 2
OrderAddOn = TextBox5.Text was Pocket
OrderEachPrice = TextBox6.Text was 10
OrderTotal = TextBox7.Text was 20.00
On submit a new array would be created and would be something like this:
Dim ArrayName(,) As String = {{"Sean", "123456", "Large", "2", "Pocket", "10", "20.00"}}
BUT a new array has to be created each time the submit is clicked.

I am working on a tic tac toe game and it needs to have a file menu with a new game option. i was wondering if there is a line of code that will accomplish this for me instead of having to manually enter the code to remove all the images from the picture boxes and reset all my variables. reset the form?

I have a pipe delimited file with 3 values on each line, something like this:
0001|234587|Bracket, 3 x 3 x 0.125, Steel
0001|254378|Bracket, 4 x 4 x 0.125, Steel
0003|234587|Hinge, 4 x 4 x 0.125, Brass
The first Value can be duplicated in the file, the second value also can be duplicated. There are no instances of BOTH values duplicated on 2 or more lines. I need to read another file and get the first 2 values, then look up those two on one line to get the proper 3rd value. The "other" file looks a bit like this:
0E0522070001EF54ED7823458700FF00FFA5A5A5A5
-----------XXXX-----------XXXXXX--------------------- (X's are the data, the rest is filler to comply with some code unknown to me)
Right now I have code to read all into an array (split on vbcrlf), then split each line on "|" and populate three arrays, I then go thru every element of the first column that matches the value I am looking for and test that the second column also matches the second value and if so, return the third array contents at the same index. This seems crude and inefficient. Cannot use a hashtable (I don't think) as it only supports 2 values. A List(Of) doesn't seem to work either and I don't want to use a database.

I am trying to do the following:
Public WithEvents frmButtons(999) As Button
And then use it like this:
Private Sub frmButtons_Click(ByVal sender As Object, ByVal index As Long) Handles frmButtons.Click
Where the index variable has to represent the object in the array like this:
frmButtons(index).Text="..."
But it gives me an error:
'WithEvents' variables cannot be typed as arrays.

I have an aspx page which houses an iframe. When a button is clicked, a WCF is called to produce a PDF which is read into a byte array. I was storing the byte array in a Globals.vb file like this:
Public Shared PDF_Data as Byte()
The global was loaded from the parent aspx page like this:
PDF_Data = MyWCF.Create_PDF_File(SomeVariable)
After that, the iFrame's src was set to a blank aspx page, which had the following code in the page_load event:
'Write the PDF binary data to the screen (viewer)
Response.Clear()
Response.Buffer = True
Response.ContentType = "application/pdf"
Response.BinaryWrite(Globals.PDF_Data.ToArray)
However, realizing that this application will have several users who will get different PDF documents, I have learned that this is not the way to go. My shared variable would be accessible to all users, a big no-no.However, I am stumped as to how I'm going to store the byte array and make it available to a child aspx page from it's parent.

I need to call again my gameplay form after finishing 1 stage. I'm just doing the normal calling. Me.Close() then Object.Show(). (Object is the object of gameplay form). The problem is, there is a continous loop of the form its flashing. It's like it's showing then closing again ang again non stop. What should I do? Or is there another way of calling again my gameplay form?

Is there a way to force a form to reload itself? The reason I ask is I have a listview that shows the data from my database. You can add information to the database from another form but when you go back to that form the information is not updated because the information updates on the form load. So my question is there a way to just do the form_load event again?

I have a form with a browser inside. When loading this form I set the browser.navigate to a url.Now to display this form I used the: form. ShowDialog()to have the form modal (which is what I want).But now when I close this form and reopen it, the browser doesn't refresh (the navigate doesn't start)this is beacuse closing a Showdialog() form doesn't unload it from the memory. To empty the memory I used the.[code]It closes and when reopened it reload the page, but it's not modal anymore and also closing the main form doesn't close this form.So what I would like is to have the form with the browser modal, but every time I load it, it should navigate to the url set.

I am using Vb 2008 Express Edition. I have only 1 form with 10+ arrays. My app runs a few calculations and finally plots 2 graphs. The first time I run my program, everything works fine. But when I run my app with a new set of data it gives me the wrong results. Is there a way I can force my form to reload itself and act as if its running for the first time? I know I can do an Application.restart. But I don't want to restart my app every time.
Me.Refresh() doesn't work, as my form still seems to remember my old data set (array)

Basically I have a form which is used for a report, when completed it is then mailed to various mailboxes. I would like the option that if the user cannot complete the form, they can save it & reload the values into the form to use later.Some of the boxes will have quite a lot of text, so using the registry is not an option. I have looked at My.Settings but think this is for application settings not user input such as a lot of text - but I could be wrong.I've looked at freefile & got it to work with text boxes saving to a .dat file, but had a problem in that text appeared in the wrong text boxes so I assume the order was different in the load to what it was in the save?

I am building an app with multiple forms. It has a MainForm, which is the main interface, and several sub-forms that are started using buttons on the MainForm.
The MainForm Load method has some code that runs each time the form starts. This code populates various fields in the MainForm and it works fine. When I click a button a sub-form loads. I update some data there and then close or hide this form.
My problem is this: When I close or hide the sub-form and show the MainForm again, is it possible to have the MainForm Load method 're-run', or execute again? I presume I might be able to add something to the sub-form "Back" button event that runs when I hide or close the sub-form. I've tried a few variations of "frmMainForm.this" and "frmMainForm.that" with no luck.
I want to do this because the MainForm Load code will pick up the changes I made in the sub-form and display the updated data in the text fields of the MainForm.
