Close Forms Created Programmatically?
Feb 21, 2009
In my program it detects if there is more than one monitor connected. It then creates a form on each monitor screen and you just click on the screen that you want the program to run on.
Here's where I'm having a problem. Everything works great, but when I load my MAIN form how would I call those programmatically created forms? I can't just do frmYou.close.
Here's the code I use to create the forms.
Public myScreen As New Point
Public ScreenReady As Boolean = False
Public sX As Integer'holds screen x width
Public sY As Integer'holds screen y height

In a program I'm working on, I want a "Loading..." dialog to close when it can't log in to a site using the username and password provided by the user. Basically, I have the code set up right because the function it is supposed to carry out when that occurs does work, but for some reason it ends up in some really weird stuff happening. In the Loading form, I have it set to do "Form1.Show()" and then "Me.Close()", assuming it would simply show the login form and then close the Loading form. However, when this happens, the Loading form closes, and then for only an instant Form1 shows, and then the Loading form shows and Form1 closes. This happens forever until I stop the debugging, and I can't seem to figure out why. Am I using the wrong method? What exactly does Me.Close() do anyways? All I want to do is close the form and open another

I have a Tray icon in my application. I am showing the balloon tip for 20 seconds, when I am loading something in the background. But, if the background load gets completed early, say in 10 seconds, I would like to hide the balloon tip. Currently the only way to hide the balloon tip is to click the close icon in the balloon tip.

After searching Google, and finding only answers to XML indent, "just use Visual Studio's auto indent" and "that would be crazy to write your own auto-indenter" I've decided to come to the good place: StackOverflow.Question:
1. How do I add an 'indent' to a programmatically created file?I would be generating the files via the System.IO class / streamwriter, unless someone can tell me of a better way, I just want to generate a file from my asp.net page, a windows app or possible a batch file (well, maybe not this last one)... to generate a class file, such as Employee.vb OR EmployeeDAL.vb

In a Windows Form application (VB.NET) I have a combo box and under certain conditions, when the user opens the DropDown list, I want to display a warning message.All of this works well: In the DropDown event, I check the conditions and if required I display the warning message.The problem is that when the user clicks on Yes on the warning message, I move to another tab on the main form and the drop down list still shows even though I've moved away from the tab containing the combo box.I've searched quite a bit and tried to set DroppedDown to False, call OnDropDownClosed, etc but nothing worked.It seems that when I try to close the drop down list from within the DropDown event, it doesn't work.

I am attempting to import items from a legacy issue tracking system stored in an Excel sheet into Team Foundation Server. I loop through the rows of the Excel file successfully, and I can create new work items, but they are always in the Proposed state. If I attempt to change the state to Closed, then call the Validate method for the work item, I receive a validation error on the State property - InvalidListValue{4}.
Dim MyProj As Project = store.Projects("MyProject")
Dim WIT As WorkItemType = MyProj.WorkItemTypes("Task")
Dim WorkItem As WorkItem = WIT.NewWorkItem()

how to connect a SQL Table to a DataGridView that was previously created programmatically. Basically, at run-time the user names and creates several empty SQL Tables and DataGridViews. After that the user selects from a combobox the name of the SQL Table and DataGridView that they want to import data into, then clicks a button named "Import"...after clicking "Import" the user navigates to an Excel file, chooses a worksheet, clicks a "Continue" button and then the code successfully connects to the Excel import file and SQLBulkCopies the data to the SQL Table...next I need the imported data in the SQL Table update to the DataGridView...this is the part I can't figure out.
The challenge is the datagridview isn't hard coded it was created and named programmatically at runtime. So now the user selects the name of the SQL Table the data resides in and the name of the DataGridView from the combobox "moduletableCB" and I need the code to update the datagridview.

Now everybody knows that creating GUIs that have lots of repeated elements that are evenly spaced by hand is for chumps; all the cool kids use loops and add them at runtime. Given that being one of the cool kids is one of my top priorities I decided to give this a go - as my current project involves creating a grid of check boxes and then chunking them together under one event handler. In my experience - an nice effective way of dealing with grid like structures (2D arrays if you will) is to use nested loops such as:
For intY = 0 To 9
For intX = 0 To 9
Dim chk As New CheckBox

I have a situation where me.close() doesn't close the form. I have a form with a button with the code seen below. What happens when the button is clicked is the new form shows, but the original form(calling form) is still there. When I go into debug mode, I can see the me.close() execute, but nothing happens (calling form stays open). When I close the second form both forms close. If I comment out the call for the second form to open the first form closes without problem.
Private Sub cmdNext_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdNext.Click

I have code that refers to controls like buttons and labels and textboxes (obviously), but i want to create them programatically, how can i create a button or label that is on a form that has also been created programatically. Here is what i have:
Dim frmIndashone As Windows.Forms.Form
Dim vscPage As Windows.Forms.ScrollBar
Dim lblPageNum As Windows.Forms.Label
Dim txtVector As Windows.Forms.TextBox
Dim txtPageCode As Windows.Forms.TextBox
I am asking because i have a With statement that assigns different values to the different things that looks like this below:
RaiseEvent Load(frmIndashone)
With frmIndashone
.vscPage.min = 1
[code]....
But i am told on everyline of the second snippet that vdcPage, lblPageNum, txtVector and txtPageCode are not members of windows.Forms.Form, How can i make them members?

I have a form which when button1 is pressed creates and displays a new form. From this form a user has the choice yes or no buttons. Each button has its own handler and script it executes. If yes is clicked i want to run the script and then close both forms. I used me.close() and that only closes the orriginal form and leaves the dynamically created on open. If I place a call to form2.close() in the yes handler sub I get an error that it is not declared. How can i close this second form?

I have a drop down menu, and based on which item is selected, I call a web service and then dynamically create some text boxes.The first time I drop down the menu and select an item, it works perfectly, and the text boxes are created and populated dynamically. However, the next time I drop down the menu (after the first postback), and select something different..fter the second postback, the original values remain in the textboxes.

i have a problem with trying to get 2 forms to close at different times using a timer on each of the 2 forms.
This is my form layout:
Quote:
frmMain
Frm1
Frm2
Frm1 and Frm2 are identical to each other. FrmMain has 2 buttons on it. One button to call Frm1 and the other to call Frm2.Frm1 and Frm2 each has a timer. It counts down to 0 and then does a .close(). However, if i pause between clicking the second button they both seem to always disappears at the same time.I would do something like this...
Click on the first button (showing the Frm1 form)
wait about 10 secs...Click on the second button (showing the Frm2 form)they both are shown on screen...hen they both disappear at the same time.... which shouldn't happen since i clicked the Frm2 box 10 seconds AFTER Frm1... So Frm1 should hide before Frm2 does...but it does not.

I have two forms frmMain and frmNew, and one module modMain. In modMain I hold public variables which are needed for application. My question is how to open and close those two forms when needed? I ask this because if i set frmMain as startup form, then when closed, application will end, and one of those two forms will always be displayed. Also if I set frmNew as startup form, then when I close this form, application will also end. Is there a way to do this from module or something so my application won't end after closing and opening any of those two forms?

I have a panel with 5 labels and 5 listviews in it. By default they are hidden. At runtime I want only the ones shown that are needed. For example, if there are enough players for three tables then three tables should show up. I know how to make the controls visible, but not sure how to control how many are actually displayed. I also think I may have to do seperate loops and seperate the control types?
Private Sub Set_Tables()
Dim tables As Long
tables = Math.Ceiling(NumPlayers / NumPerTable)
