Is there a way to find the opened application, find a button within the application, click a button and know it was clicked? Is there a way to read the contents of a textbox within the application?

Within VB.NET, trying to find an easy way to in a sense check the check-box "Use Windows to configure my Wireless Network Settings". This is an option that forces windows to use your wireless over third-party programs that may try to steal control. I am aware this requires to have WZC enabled within services and that's something that can be easily accomplished one way or another.
I doubt or rather cannot find a proper registry value or API call to check or initiate such a task.
I've completed projects similar to this in the past but this one has me stumped. Trying to retrieve text from a text box in a third party application. Using SPY++ I found that this control is the second control in the list so I coded the following: Dim parentWindow as integer = windows.ReturnWindowHandle({windowname})
If parentWindow > 0 then
Dim childWindow as integer = FindWindowEx(parentWindow, 0, Nothing, {child window name})
Dim field as integer = 0

This worked great. Closed the app, came back the next day and this same code did not work. Used spy++ and found that the control had moved to the 4th position. Closed it, reopened it, this time it moved to the first. What is the best way to find this control each time when there are are 50+ controls on the screen and they all appear in spy++ like this:
Window 0022063A "" Edit
Window 00270652 "" Edit
Window 001A0630 "" Edit
and they continue to rearrange themselves each time the application is closed and reopened?
I would like to be able to set Control visual properties such as color, boarder, flat style, etc. on the base class of the control so that as I add new instances of the control, each instance inherits the visual properties of the base. I have tried using Application Settings but it appears as though I need to reference an application setting manually each time I add the control to a form. This is a Windows Form question.

View 2 Repliesi frequently have troubles with the dock property. it seems that either the order of creation or adding to the parent control determines whether or not a control's dock property supersedes another's. e.g. a control with the dockstyle fill will overlap with another docked control on the same parent. does anyone know what the rules are to determine how docking will behave; particularly in dynamically created GUIs?
View 2 RepliesIs 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.
If I need access to the value of a user control's property BEFORE PreRender, would I need to base the custom control off of one of the preexisting data controls (repeater, listview,etc.)?One of my user controls features a gridview control that is configured based on the user control's properties on which it resides. Several of the key properties alter the SQL Statement for the underlying recordsource. I'm now in a situation where the property that sets the WHERE statement for the SQL Statement needs to tied to a value in the user control's parent FormView. Think of the formview as displaying a customer detail record. The user control takes the customer's account number and then displays data from a related table such as Customer Contact Names. Since the gridview is created before the control's prerender event, working within the prerender event doesn't seem efficient.

I have created a custom class, which contains a panel and a label on it. I added to this class a pcaption property, which holds the label text. This property is browsable and I can change its value.But when I drag the custom control to the form and change the pcaption property, it has no effect. Even the <Defaultvalue> has no effect. Why?
Here is the class code:

Color values are unimportant, you can change it.
I have a number of pages which implement the same interface:[code]The function doSomethingToTextBox takes a textBox item as a parameter and performs some action on it.I know the textBox is contained on every page which implements my interface, and that it has the same name on each page.My question is: how can I declare the textBox as an interface property? This will remove the need to pass the textBox as a parameter to doSomethingToTextBox()I must also add that I'm currently accessing the TextBox using get/set methods defined as part of the interface - I don't want to have to implement these methods for each page as they are exactly the same on each page.

foreach (ListViewItem i in ListView.CheckedItems) { //error: Cross-thread operation not valid: Control 'ListView' accessed from a thread other than the thread it was created on.

In this example the IsEnabled property of my button is bound to the selected rows "Local" property of the grid and it works just fine:
<Button DockPanel.Dock="Bottom" Width="100" Height="100" IsEnabled="{Binding ElementName=dataGridRestore , Path=SelectedItem.Local}"></Button>

I'm writing a custom user control for my asp.net site, for storing datetimes. It has two properties:
Private _includeTime As Boolean
Private _value As DateTime = Nothing
Public Property IncludeTime() As Boolean
[code]....
I call my custom control in this way:
<my:DateTimeInput runat="server" includetime="true" ID="txtWhen" />
This sets the includetime property correctly.In my backend code I also do this on page_load:
txtWhen.SelectedDateTime = now
When I step through with the debugger, I see that the property gets set, BUT when the page_load of the control itself loads, the property value is reset to nothing!

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
lbltime.Visible = IncludeTime

View 1 RepliesI just wanted to confirm couple of things.
I) Code snippet:
cmb1.Datasource= dt;
cmb1.Valuemember = "value";
Does the control rendering happens 2 time for the control, 1 more time extra because of the value member getting changed after data source assigned. Is this so?
II) How can I trace these re-populations in C#? I just wanted to debug and see and confirm?
