View 3 RepliesI'm adding rectangles to a wrap panel like this:
For i = 0 to 20
wrapPanel.children.add()
next
I would like to use this loop because I don't want to specify the limit:
Do
wrapPanel.children.add()
Loop
But how can I break the loop when the wrap panel is filled? For example the loop would stop when the wrap panel can't display a rectangle in its full height or width.
I got a panel that i am adding labels to. I have autoscroll enabled on it so when they fill the viewable space it scrolls. but i need to put the labels to the left unviewable space(when left scroll is already at 0) The label is placed but i dont get the scroll bars and i cant force it to scroll to a - value.
Is this even possible? Same thing with UP.
Or is the Scroll only limited to Bottom and Right?
I need to center the red panel in the middle of the dark grey panel, when you resize the form the red panel should be in the middle, and the red panel can't be resize, anyone have a code or property to do this?
View 2 RepliesI would like to add an effect where a panel sweeps out of the way to make room for another panel. This is sort of like a sliding effect, and I think at one point in time this could be seen on Apple's website under their product pages. I came up with some code, but it isn't working.

When a user is editing a given piece of data, they're allowed to add messages/comments. These are stored as child records in a SQL database. Clicking on the Add Message button brings up a panel (pnlMessage) courtesy of the AJAX ModalPopup Extender. This takes some input and, when the "Send Message" button in the panel is clicked (I learned the hard way to NOT make that the 'OkButton' property), the message is stored in the database and an email is sent to the intended recipients. No problem there.
However, I need to be able to allow the user to add new email addresses (so long as they are registered in our database). I have another ModalPopup / panel combo (pnlSearch) that's tied to a button on the previous panel (pnlMessage).
The user is supposed to be able to add an email or click on a search button to populate a list to choose from.
The pop-up panel (pnlSearch) comes up just fine, but clicking the "Lookup" button (which instigates the search and returns a collection of records that the user is supposed to pick from) closes the panel.
Previously, I ran into the problem of having the Button.Click event never firing when I put the Button into the "OkControlID" property (the CancelControlID works fine since I don't want to do anything). Removing the "OkControlID=Button" line allowed it to work perfectly with the Button.Click event firing as expected.
So now I have the Search panel with a button for "OK" and a button for "Search" - but the panel should stay up and visible after the Search.Click does it's thing. Am I missing some property that basically says "don't close the panel when this button is clicked"? Of course, if I bring up the panel again in the same session, the results from the previous effort are there (the search results).
I have a TopBar, A LeftBar, A VScrollBar, A HScrollBar and a Panel inside a SplitContainer Panel.The issue I'm having is that when my SplitContainer Panel is small enough to enable one of the ScrollBars, I will slide the ScrollBar and then when I resize the Split Panel, my Panel1 is staying where I scrolled it too.I'm having troubles thinking of the correct code to fix this.

I was trying to move some dynamic control within the parent container like panel or a group box how do i do that?
View 12 RepliesI'm working on a visual studio 2008 VB.Net project (.net framework 2.0), and am having some trouble with the Panel control using a fixedsingle border. As a small example of the problem, suppose I have one Panel2 contained inside of Panel1. If the Left position of panel2 is set to 0 (meaning it's border is up against the left edge of Panel1), the left border will show as bold, and slightly indented.
<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _
Partial Class Form1
Inherits System.Windows.Forms.Form[code].....
What I'd like to see is just a single line, not bold or indented, where the two panels borders are equal.Is there a property or custom paint technique I could use to achieve this behavior?
Is there a simple way of tracking the change of an Mdi's children i.e. when they are created and closed, something like an event OnMdiChildListChanged (I realise this doesn't actually exist).
I am also aware that I could have a method within my Mdi that handles the creation of child forms and logs the state of them or even create an Interface that defines that a child form has a "NotifyParent" method that is then called on close of the form, but i was wondering if there was any built in events that i could plumb into?
I have four children in a parent container. Each child form is a test for the user to type correct answers into text boxes. Option to open each form is on a menu strip in the parent. In form load, I have disabled all but the first form option. I only want the second form to become available if the first form answers are correct. I would like to figure this out on my own as much as possible. I have searched on line but since I am not sure what to ask, I have not found and answer. Can someone get me started in the right direction? Perhaps some reading that would explain how to go about this, or what I should be typing into google to get what I'm looking for.

I'm sifting through the dump of AniDB titles and everything works except that it only sees 7161 elements instead of 9200. Anyone have any idea why? It's not calling an exception on the load method as if something is wrong. Even when I change it to just take the root element and then get the count of children, it gives 7161. Like it doesn't even see the last 2000.
This is for a mapping/plotting program.
t.panel is the main panel and it has too much content to fit in one screen so there are scroll bars. x.panel contains the horizontal scale for the data points in t.panel. I drew the scale using a bitmap and set it as x.panel's background.
Setting x.panel's horizontalscroll.value = t.panel's horizontalscroll.maximum doesn't seem to work. I think this is because x.panel's doesn't have any content that causes it to need scroll bars.
A common problem I have come across when migrating from VB6 to VB.NET is that to change the focus between MDI children, you can't just click any control to give that child focus, you must click its title bar. The solution that I have found works is to enter the child form's Designer and change the following:
Code:
#Region "Windows Form Designer generated code "
<System.Diagnostics.DebuggerNonUserCode()> Public Sub New()
MyBase.New()
'This is required by the Windows Form Designer.
InitializeComponent()
[Code] .....
This needs to be done on all child forms in the project. If one form does not have the fix, once it's opened, the bug will return even when the form is closed.
I would like to turn on an app in the background that disables or temporarily remaps all but the alphanumeric keys while they are using my laptop if possible.
View 1 RepliesI start with VB 2010 since a short time.I need to check in a Treeview if a node has children or not.In VB 6 there was the property clildren that allow to understand this.
View 1 RepliesI'm trying to remove all children (and sub-children) of a Grid in WPF (I'm really new to the whole WPF business). Is there a good way of doing it programmatically? I need to do this so that I could leave an empty canvas (Grid) at one point and draw other stuff on it.
View 1 RepliesIm new to treeviews so I hope this is not posting a problem that has been covered. I want all the children of a checked parent to also be checked. I have found various snippets that can achieve this but only for one or two levels. When I expand further than 2 levels the children are not checkeds. What am I missing? I have managed to find this piece of code that I am using in both the "AfterExpand" and the "AfterChecked" events to achieve the result. There must be a better way.

i make a parent and children form and when i show children form and drag into parents form , when parents is little to show the children form , parents form enables the scrollbar and then show the chilren form better , how can i do something that avoid this status ( don't show scrollbar into parents form when the children form is bigger than it)?

The warning disappear but then the literal control isn't anymore being displayed on the page... EDIT Note that the code come from a Microsoft web page: [URL]
I need to modify a xml file (actually a .rdlc report file) and add some nodes which have a lot of children nodes (and those children nodes again have children nodes). Actually they are almost the same strucutre, like this one:
<TablixRow>
<Height>0.23622in</Height>
<TablixCells>
[Code].....
and it will add my specified NS. (like I said, XElement.Parse(string) won't add it) So now I can construct the correct node. For my second problem I still can't figure out: I can't navigate to the target node by using the element name since it won't search for correct NS.
My application creates MDI Children programatically. I have a frmBrowser as an MDI Child which I create multiple instances of. There are several other MDI children in the MDIParent. How do I only cycle through the frmBrowser MDI children?
For Each Child As frmBrowser In frmMain.MdiChildren
'perform action on child
Next Child
The code above gives an error for all the Child that aren't of the type frmBrowser.
I have two mdi children forms open. I would think that clicking on the non active form would change the focus from the active form to the form I just clicked on. It only does this if I click on the title bar. Then the focus changes. But if I click on a control on the non-active form, focus does not transfer.

I have an MDI application that shows a child window, obviously. I want multiple instances of this child window to be possible. However, I only get one. The first one will close out and the new one will show.
Dim newWindow As New frmWatcherWindow()
newWindow.MdiParent = Me
newWindow.Show()
One would imagine that clicking anywhere within the MDI Child form (or on any control) will focus that form. But in my application I can only focus a MDI child by clicking on its titlebar, which is an abnormal behavior on the part of the user. My forms are filled with either controls or panels so I don't have the luxury of just "clicking on the form." But clicking anywhere within it should focus it.
View 1 RepliesI'm trying to msgbox all the children nodes that exist in a treeview, however i was not able so far to msgbox except the first nodes in the first level of bracnching in the treeview, i want to go more in depth & msgbox all the children nodes.
Dim child As TreeNode For Each child In TreeGraph.Nodes("A").Nodes MsgBox(child.Text) Next child
How do you set it up so that a treeview control will select/deselect all children of a parent when it is selected/deselected? Is there a property you set or do you have to write code to do it?
View 3 RepliesI'm working on a drag-and-drop method to copy items from a listview control to a treeview. I've got the drag and drop working, but I'm hoping to limit the ability to drag items that create a child of a child. Ideally, if someone drags an item from the listview to the Treeview and the drop the listview item over a child, it would drop the dragged item to the parent.
