How do I address a specific control that is on a UserControl? For example, I have a UserControl containing a TextBox, that I add to a form in code. Now I want to set the text of that TextBox, but I'm not sure how to do that.

in VS 2008, is there a way to design a ContextMenuStrip in a designer without a relation to a specific Form or UserControl class? For example,if you need the same ContextMenuStrip in Form1, Form2 and Form3, in which of them am I to design the ContextMenuStrip? Do I have to add a "pseudo-Form" to the project that contains my shared ContextMenuStrips and create only one instance of that Form, or is there another way? I consider this a programmatic hack, that's why my question is whether the IDE offers something better.

View 12 Repliesim in the process of using vb.net code to return the ip address of my machine its working sorta correctly i can get the right ip address if i change the addresslist.getvalue(0) from [0] to any where up to [5]this im guessing is an array of information in the network adapter or something im not real interested in the other information in the other values my problem is depending on weather i have ipv6 options enabled in my adapter settings the true(192.xxx.x.x) is in value(2) for on and value(3) for off also i tried it on another machine and it came back as value(5) of 12 my problem is i can display every value() that has information in it in a text box but i cant make the program find the right address to use(192.xxx.x.x) this code runs and produces a multiline textbox with up to 11 lines of data in it and the ip address is visible in the list of data
Dim myIPs As System.Net.IPHostEntry = Nothing
Dim ip As String
Dim h As System.Net.IPHostEntry = Nothing
[code]....
but is there a way to either compare the adapter address list to a mask to get the correct value() for the ip address or is there another way to return the ip im not aware of?
What's the best way to monitor a specific address in memory? And is it possible in theory to block a certain address being written to?

I am needing to obtain the mac address of a specific computer via an ip address. Most of what I've seen returns to me an array or list of items.
I have a system with multiple IP address. But I'm allowed to initiate SOAP Request only from one IP address. How do I obtain that in VB.NET.

is it add control to a form and add control to a usercontrol is using same method like me.controls.add(newpanel)?im a little bit confuse here because that way is not working. im trying to add a panel, to a usercontrol at runtime. the usercontrol is also added at runtime. for e.g. i have click add bar menu, than a usercontrol appear. then, when the usercontrol is selected and i click on add note menu, it will add a panel that contain labels to the usercontrol. this is what i have done. the 'me' is the usercontrol and i put this code under that usercontrol load event.

View 2 RepliesVB.NET 2.0 Framework..I developed a control that implements IExtenderProvider in order to attach to controls and display a form for translating of the text of that control.This works great on regular controls on the form but the IExtenderProvider is not attaching to controls on UserControls by default.Is it possible to modify the UserControl or my IExtenderProvider control to enable it to attach to controls on a UserControl?
View 1 RepliesI've built my first usercontrol for use in a GPS Mapping forms app.
pic1 shows "panel1" containing some picturebox "tools" with a map(another panel containing a picturebox) underneath.
Pic2 shows that I dragged the map and the "tool" have not moved with the drag.
"panel1" also contains my usercontrol( this will show a transparent map scale). My usercontrol and all the "tools" definately have the same parent - ie "panel1".
If I resize the form to cause a re-paint of all the controls I get Pic3 - the red T bar (my usercontrol) will be the map scale.
Everything looks OK until I drag the map - the user control goes with the drag. Pic4 shows that the usercontrol image has been erased as it passed under the "tools".
I don't understand why the "tools" stay put and on top of the map and the usercontrol does not - even though they all have the same parent.
I have a custom UserControl that contains just one TextBox. When I set the control to Enabled = False, the TextBox is disabled but the control is not (control still fires the Enter event).
How do I ensure that the UserControl will not receive focus?My Enabled Property Looks like this:

Public Shadows Property Enabled As Boolean
Get
Return _Enabled
End Get

View 2 RepliesI have created a usercontrol that contains two rectangle shapes to create a unique button effect and a rounded-corner rectangle shape serving as a border to provide a look similar to a group box. It also contains two labels, one for use with a Text property of the control and the other to indicate the status of expansion of the control. The control is designed to collapse itself when the "button" is clicked leaving only the "button" visible. Clicking it again toggles this affect. I've dubbed it an ExpansionBar. It is also designed to be a container control so that I can add controls to it and allow these to disappear when the bottom portion collapses. The problem is that the controls contained in this usercontrol cannot be accessed during runtime. In other words, I can add a checkbox to it and it will disappear correctly when the control collapses, but I can't select the checkbox to check it... same thing with any other controls, you can see, but can't touch. I'm a novice developer, so I'm sure I'm missing something obvious.

View 8 RepliesI have a form with about 48 checkboxes.I have a public sub that reads a webpage, parse the text of that site to get the values that correspond to these checkboxes.For example: one of the lines would be: "Exterior = 255", or "Street = 0".I do have check boxes that called "Exterior" and "Street". the question is how I can get my sub to address the appropriate control so I can set its "checked" property based on the text read.
View 3 RepliesI have a Windows Form that contains a custom control container as a UserControl. For the sake of this question, this custom control container is called Dashboard. This container called Dashboard contains numerous other controls depending on their permissions. I need to raise events that are contained on these controls through the Dashboard control and over to the Windows Form.
How can I bubble up the event? I'm using VB.NET for this project, but can convert C# into VB.NET.Also, to complicate matters, the main Windows Form is a VB6 project. So, I'm using the InteropFormsToolkit to accomplish this.
I have two UserControls on a MasterPage. DataEntryUC contains several TextBoxes and DropDownList. NavSaveUC contains navigation buttons. When the user clicks on a navigation button, I will be saving the data entered into DataEntryUC from the NavSaveUC UserControl.

I have a usercontrol that has a main form and calls another form within the usercontrol to get some data from a database that allows the user to select some items from a CheckedListBox control on the sub form. I want to pass the selected items from the CheckedListBox back to the main form and display the results there. I have a public property called DBList of type List(of String) on the main user control. If I create a reference to the usercontrol form the second form within the usercontrol I get a new instance of a user control. All I want to do is set the property on the usercontrol and close the secondary form. How do I reference the usercontrol from the form within the usercontrol?
Code in UserControl:

I am making an invoicing application. I have a label (lblCost) inside of a UserControl (InvoiceEntry) inside of a FlowLayoutPanel (pnlEntries). InvoiceEntry represents a line item on the invoice, and pnlEntries is the "body" of the invoice. pnlEntries can hold several InvoiceEntry controls.
I am attempting to sum all of the lblCost values from each InvoiceEntry control to make a subtotal, and I want that subtotal to change automatically if costs are changed (e.g., a change in quantities being ordered). Is there a way to handle when the lblCost.Text property of any of the InvoiceEntry controls contained within pnlEntries changes?

' Instantiate objects of the various database interaction classes.
