Jumping Between Forms - Making A Form Visible And Not Visible
Jul 17, 2009I'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 RepliesForms :: Random Functions - When Start Program And Click Picturebox - Same Card Will Always Come Visible
Mar 30, 2011Okay, so I'm doing a card game and I'm trying to set that when picturebox (PictureBox1) is clicked, a random card from 13 cards will come visible. Problem is, that when i start the program and click the picturebox, the same card will always come visible. As you can see i've put a button (Button1) which will hide every card. If I press Button2, then Button1 and then the PictureBox1 it will show differend card, but the cards which come visible are always the same.
e.g i press PictureBox1 (which will make card visible), then Button1 (which will make PictureBox1 non-enabled) and then Button2 (which will hide every card and make PictureBox1 pressable). Lets say i pressed the PictureBox1 four times and i got cards: 9, 6, 7, 3, then I close the program, start it again and press PictureBox1 again 4 times and it will show the same cards (9, 6, 7, 3). How can this be done that it will not show the same cards always?
Here's my code...
Public Class Form1
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
End

Big Panel Visible And Not Visible Based On Selections Made By User

I cannot seem to make it appear.Even if I leave it VISIBLE at design time - the objects in it will not appear.Is there some kind of nesting problem that I'm not aware of!

View 2 RepliesForms :: Listbox Faster Method For Selecting All
Dec 1, 2010I have a listbox control that has a selection mode "MultiSimple" (I've also tried MultiExtended). I also have a button that uses this code to select all the items in the list:
Dim i As Integer
For i = 0 To ListBox1.Items.Count - 1
ListBox1.SetSelected(i, True)
Next i
It works ok but the problem is that it's very slow. I have cases where there are 60 000 items in the listbox, and it takes forever to select them all. Is there any function that would select all at once (Just like ListBox1.ClearSelected() unselects all instantly)?
Forms :: Multi Column Combobox (looking For Method)?
May 14, 2010I'm using vs2008 with vb.net, and I have googled all around for a multi column combobox and I know there is not an easy way to do it in .net. However, this is my situation:I have a table in my database that only has around 4 or 5 entries, with the columns FirstName, LastName, Type. I need all of these columns for each of the 4 or 5 entries to be displayed in the combobox. I've been trying to think of simple ways to do it such as counting all the rows, selecting each cell in a loop and programmatically assigning them to the comboboxes, but I realized that the ID column for these entries have numbers that do not go chronologically. (I thought that if I counted the rows, the row number would correspond to the ID number and I could go about looping and assigning variables/concatenating them into the combobox, but this is not the case).
So I am just looking to see if anyone else has any ideas on what I can do to solve this? It's a pretty simple problem but I'm kinda out of any simple ideas.
Forms :: ProcessTabKey Method - One Of ComboBoxes Skips
Nov 1, 2010I'm trying to detect when the tab key was pressed and intercept it in certain cases. Since the form I'm working with has many fields, I've tried overriding ProcessTabKey so that I don't have a separate sub for each control. However, I've found that after adding a simple ProcessTabKey method, each time I press tab it skips one of the combo boxes. In order to duplicate the situation, using Visual Basic Express 2008, create a new Windows Forms project and add 5 combo boxes to the form - allowing each to automatically get an incrementing TabIndex.
Then add the following code the form:
Public Class Form1
Protected Overrides Function ProcessTabKey(ByVal forward As Boolean) As Boolean
MyBase.ProcessTabKey(forward)
End Function
End Class
Now when you run the project, you'll see that each time you press tab it skips one of the combos.

Forms :: Focus() Method Fails With Second Show Form?
Feb 7, 2010I have a simple login field, which works fine with the exception of one quirk. The form is set up with the tab order to go to the UserID first and the Password text box second. This works fine when the form is used the first time, but when the form is used the second time the focus in placed in the Password field. If the form is used a third time, focus is moved the OK button, that is each time moves to the next tab order. I even tried to set the focus in the Load event as in Me.txtUserID.Focus(), but this doesn't change the behavior. Again, I should note that I close the form and not hide the form.
