I'm having an odd problem when making a form visible and not visible and it not continuing to function. Here is what I have happening. I have a main form (frmMain) that is an MDIParent. On this form I have a menu to open a second form (frmCalculate) and populate a listview from Items in the database.
As I click or select items in the listview on frmCalculate the tag is read and data is pulled based on the id stored in that tag and fills in various fields on the form. This works great. However, I also have a context menu attached to the listview that allows me to perform a "what if" scenerio on the items I am calculating. When I select this menu, I hide the frmCalculate and open the frmWhatIf form where I can mess around with values on the item I had hilighted in the listview on frmCalculate. Nothing is pulled from or written back to the database here, all the information is filled in from fields on frmCalculate. It just allows me to look at rising costs and how they will affect my margins.... anyway.
If I then close frmWhatIf, it brings my frmCalculate back by setting its visible propery to true (never closed frmCalculate, just hid it). At this point if I click an item in the listview I get an exception for a null reference. IF however I never hide frmCalculate, I can open and close frmWhatIF without ever having an issue. Why do I lose the functionality to select items just by hiding and unhiding the form? As a test I added two menus to the toolbar on frmMain one called hide and one called show. I then opened frmCalculate with original menu item to populate the listview and selected a few items to test that it was working and then using the hide menu I made the form invisible and the show button to bring it back. This yielded the same exception so without even opening frmWhatIf the problem still occurs.

View 7 Repliesmake a click event for a non existing control but for example: when the end user clicks the new button(or something else) a new text box pops up with a button on the same form and when the button is clicked I want the form to open another window(or something else). Here is the the code for doing that(only the part needed):
Private Sub MenuBtnNew_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MenuBtnNew.Click
Dim Tab As TabItem = TabControl1.CreateTab(NewDialogBox.NameBox.Text + NameDesign)
Dim Panel As TabControlPanel = DirectCast(Tab.AttachedControl, TabControlPanel)

View 3 RepliesI have an application in which the windows form has 3 panels. Under some circumstances, controlled by the User I want all three panels visible, in other situations I want one of the panels not visible.
The program works if I use the code:
Panel1.Visible = False
Panel2.Visible = True
The program also works if I use the code:
Panel1.Hide
Panel2.Show
Is there some advantage or disadvantage to either of the two approaches?

i was wondering this: what is the difference as in response.. should i use the .visible or the .show/.hide option.. by setting the .visible to true/false, the controls (in my case) will only appear visible or not.. by setting them to .show./hide, i guess they unload from the form, and reload in their previous state.. do correct me on this .. is this more memory use than the .visible option or the other way? i am currently designing a project containing a lot of panels/buttons/etc., that has the .visible option included for these controls. should i be using the .show/.hide option instead, or does it even make a difference, since i cannot tell from the response of my project when using either/or..

I am trying to make a customer class that will simply make a bunch of controls (hotspots) Visible value = False.
For instance: WinStartSpot.visible = False
Thing is I have roughly 60 "spots" that need to be turned on and off as the user clicks through the program (its a very simple OS simulator) I tried to make a class using boolean return but that failed miserably. how to code a class like that?
The basis of the program is that the user enters info into to text boxes then hits a button, when the button is clicked and all the parameters are met, the visible property of a rather large picture box becomes true. What I want to do is have the form start off small, just big enough to hold the labels, text boxes and buttons and then resize when the picture box is made visible.
View 2 RepliesI have the following in my code:
lblIsInvalid.Visible = True
I have noticed that even after going to this line, it does not make the label visible. I am thinking this may be a refresh issue as the last line hit is lblIsInvalid.Visible = True. Is there any refresh property that I may not be aware of for a label control.
I have set up a GridView as set out below. You can see there are four LinkButton's per row. What I want to do is make certain LinkButtons available depending on which row they appear in.

FLbtn.Visible = True

Also when I click say the FormLinkBtn, how do I determine the value of the fields in that particular row?
I'm making a project that has a bunch of different types of calculators in the same tab within a tab control. To organize these calculators, I put each one in a groupbox, there are about 5 or 6 in all. When I was finished designing all of them, I placed all the groupboxes in the spot they needed to be, but once I started creating the events for them to be visible or not visible there are a bunch that don't show up. I think it has to do with the fact that VB thinks that the groupbox is part of another groupbox that isn't visible so it doesn't show.
How can I go about only showing a single calculator at once in my tab?
I have a tool strip menu item who's collection is filled from a subroutine that loads all available com ports on the computer at for load. I know how to generate a click event for menu items that are filled, but not if they haven't been filled already. I guess it doesn't need to be a click event. It just needs to do something that I can get the .text and use it to configure a serial port.

View 4 RepliesAlright, so what I'm looking to do is make a dock or some other thing that I can hide/show for programs. Kind of like a shortcut holder. how to approach the issue. I'm thinking maybe I could make a new button based on some settings in the VB thing, but that seems rather inconvenient.
