Get Sub To Address Appropriate Control / Can Set Its 'checked' Property Based On Text Read

Jan 2, 2012

I 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.

Read The Text In The Memory Address Of The Program?

Jun 22, 2009

I need to make a program for my school (I`m the principal), that reads the text in the memory address of the program and write it down in a txt. I already have the address numbers. For more information, I use VS 2008.

I was trying to make one code to get the memory address. So, after I succeed this, I'll make the correct program.

The code I made(adapted from [URL] returning-0 ):

Public Class Form1
Private Declare Function ReadProcessMemory Lib "kernel32" (ByVal hProcess As Integer, ByVal lpBaseAddress As Integer, ByRef lpBuffer As Single, ByVal nSize As Integer, ByRef lpNumberOfBytesWritten As Integer) As Integer

[Code].....

.net - Make A Class Property Behave Like The Checked Property On RadioButton?

Jun 1, 2012

I have a very simple class that holds a few public properties - ID, Text, Colour, etc. and a Boolean called 'SelectedItem'. Just like the Checked property on RadioButtons, only one item can have its SelectedItem property set to True within a particular group. Note: there will be several separate groups (lists), each allowed to have only one item with SelectedItem = True.

My first thought was that I would probably just have to handle everything outside of the class, setting SelectedItem to False for every other item in a particular list when another item was selected. But that seems rather inelegant to me. So I've been trying to think of how this might be done within the class. For example: could I perhaps have a private string property called say "GroupName" - set in the New sub when adding a new instance of the class - and then use a private shared method to set every item's SelectedItem property to False, provided the item has the same GroupName as the newly selected item? I would have a go at doing this but I have no idea how to enumerate every instance of a class from within that class, or whether that's even possible. Is it? Or is there another (better) way to achieve my goal? Here is a cut-down version of what I've got so far:

Public Class ResourceItem
Public ID As Integer
Public Text As String[code]....

As can be seen: instead of instantiating a new ResourceItem and passing that as an argument to the manager's Add procedure, I'm simply passing the details of the new item and the procedure is creating the item from those. I don't know whether this is a good or bad idea - please advise - but I've done it because I couldn't figure out how to make the SelectedItem property only writeable by the manager, so I wanted to avoid having directly accessible objects that could have their SelectedItem property set to True without it deselecting all the other items in the same group. Of course that still leaves the possibility of setting a variable to one of the manager's list items and setting it from there, so I would still like to know how I could prevent that, if possible.

UPDATE: I didn't use the code above in the end, deciding instead to go with Cyborgx37's solution - which seems to work perfectly well for me despite the warnings about best practice. I also realised I would need to use the same class in another scenario where multiple items could be selected, so it was easy to add a Boolean property to the manager to enable that.

Bind Control.Text Property To Control Position In FlowLayoutPanel?

Jun 6, 2012

Is there a way to bind the text property of a control to an expression? I have a user control that I add to a FlowLayoutPanel. You can see I have 4 controls in the FlowLayoutPanel below. The first control is a LinkLabel and the other three are my user controls which are numbered 1, 2, & 3. I'd like to bind the label that shows the 1, 2, or 3 to the user controls index within the FlowLayoutPanel.

If I happen to remove the 2nd user control I want the 3rd user control to now display 2. I could use the FlowLayoutPanel ControlAdded or ControlRemoved events, but wanted to see if I could do some binding first.

Changing Text Of Custom Control Based On Text Of Another Custom Control

Jan 11, 2010

I am using custom textboxes and I need to be able to set the Text on txb1 based on the Text of txb2. I have simplied my code to the following:

Public Class customtextbox
Inherits TextBox
Public Event ControlReset()

[Code]....

So, when txb1 looses focus, if its Text is "fried", then it sets off txb2's ProcessAlert function. I had tried to change the value of txb2 Text in ProcessAlert function, but didnt work, so I tried to get it to raise an event instead, which then tries to set the Text property. However I still cant set txb2's Text property. The Text property seems to be set for the duration of the "life" of the Event handler. When I step through the forms controls within the Event handler, the changed Text value is there, but not outside of the Event handler.

Using ApplicationSettings To Store Checked Property For WinForms RadioButtons

Jun 1, 2009

I have a WinForms dialog box that contains 3 radio buttons. I am using ApplicationSettings to bind the Checked property of each of these RadioButton controls, but it doesn't do what I am expecting it to do. Now I have to click each radio button twice before it gets checked and the selected radio button is not being persisted.Is there a line of code I need to execute when the form is closed that saves the user settings?How do I eliminate the need for 2x clicking on the radio buttons?Is there a better way to persist this type of user setting? I do have a public property on the dialog box class that gets/sets an enum value based on which radio button is checked, but I didn't see an easy way of binding that property to a user setting. Should have specified that I'm using vb.net. I think that means My.Settings instead of Properties.Settings.
