VS 2010 : Activating Button And Viewing Text File?
Dec 6, 2011
The user will be selecting a file to be read into the program. At the top of the form is a button that says "View Hourly Data File". This button is to be a link to open the data file in a text viewer. However, I would like the button to be deactivated (grayed out) until the user selects the file. Once the file is selected, it will then be an active button.
The Second:Once the user selects the file, and the button is activated, I want the user to be able to open and view-only the text file that they have loaded. It should be opening into a pop-up window.

I'm having some issues with grabbing the page source from a site. The page source that you see from pressing CTRL-U is not the same as what is displayed on the site - I had to use firebug to see the 'real' page source (source code changes over time on the same URL).This is what I have to grab the URL:
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim request As System.Net.HttpWebRequest = System.Net.HttpWebRequest.Create(WebBrowser1.Url)
Dim response As System.Net.HttpWebResponse = request.GetResponse()
[code]....
What can I do to obtain the same source code that firebug sees? In other words, how do I get the source code of a site after it has been php-altered?

We have an interactive windows based application written in VB .Net 2010. It uses Word Object to display documents in MS Word. We have a form with a button. When the button is clicked we open the Word document and maximize the Word Windowstate. When we have the Visual Studio Tool running, the Word Document is maximized and has focus, even if we are running the exe from the bin folder outside of the tool. However, if Visual Studio is not running and we run the exe, focus remains on the original form window and the document stays in the task bar.

I have built a vb.net web application. I have tried to make it secure, with all users requiring a password to get in. The only problem is that if anyone can guess (or detect using some kind of hacking tools) the url of the javascript file, they can download it and read it, without even having to log in first.
Is there any way that this can be prevented?

I am using a webbrowser control, which is used for both internet and folder exploring. How can I determine when viewing files on the local directory, which file is selected?
I ran across something in my searches saying there was a property under the webbrowser.document called SelectedItem. But this must not be in 2008.

I am trying to move from the old ADO to the new ADO .NET . However , no matter how many tutorials I read over the internet , I still can't find a way to do something which , as I believe , has to be very simple I tried to mimic the way the graphic control did but I am missing some things ... I noticed that , in the graphic way , the wizard created 4 controls :- a DataGridView control- a DataSet control- a BindingSource control- a TableAdapter controlI recreated all of them and filled their correspondent properties , but yet I can't make it work . I think what I am missing is the connection itself . I looked on the internet and I think a connection can be made and opened like this :
Dim DataBaseConnectionMY As New OleDb.OleDbConnection
DataBaseConnectionMY.ConnectionString = "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source = C:ProsoData.mdb"

I'd like to know if it's possible to, for example, place a small 32x32 icon on the left hand side of a Button control and offset the text to the right to make room for it. I know it's got to be possible, I'm wondering how easily done it would be though. Would I have to derive a custom control and then handle the drawing myself?

I need help getting the sum of a bunch of text boxes into another text box without using a button. Ive tried using TxtTotal = Val(txt1) + Val(txt2)... in the Total1_TextChanged but nothing happens. Someone once said I should use databinding but I cant see how that would work when Im using user input as the data to be Totaled. Also I dont know a whole lot about vb as I am just learning, and databinding
ps the values Im adding are in currency format. So I guess i would need to convert them back to add them, but im not sure.

I'm currently making a button which when clicked opens a file dialogue box in which the user then selects the file they want, when the file is selected the file name should appear in a text box next to the button. (Much like when browsing for a file to attach to an email) I've created the dialogue box but can only set it to show the file name in a message box when selected.

Private Sub Form2_Shown(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Shown
If RadioButton1.Checked = True Then
Label11.Text = ("Boca Juniors")
End If
End Sub
I'm pretty sure the Form2_Shown is not correct but I dont know what else to put.

I would like to find out how can I start an application when a certain process is active? for example. say I have an application and i want it to start when explorer.exe is active (witch is always). this is for testing purposes only at the moment...
the simple way I would have thought would be
Process.GetProcessesByName()
but, that is all i could figure out. I dont suppose i could use Process.Start () propriety since that will only work to call and open a process...

I dynamically create buttons on a form and use the button text as ids so that I can pass that to an SQL query to pull saved data about that button when necessary, but I also use an image over buttons that have information saved about them. What I need to know is how do I keep the text on the button from appearing when there is an image assigned to that button? By default vb.net shows both the text and the image and no TextImageRelation values allow for the image to take precedence. I tried changing the text color to transparent, but the outline of the text is still visible through the image. Is there anyway to keep the text value as it is but just show the image on the button?

How can I refresh my form? I have a button that clears all data from a text file, and the text file is displayed in a secondary tab on my form. When the user views the second tab, they have the option to press the clear button, but I would like the form to refresh so they can see that the data has been cleared. How can I do this?

I have a rich text box ('RichTextBox1') and a button ('BoldButton'), and have it set up so that whenever the user highlights some text in the box and clicks the bold button, that text becomes bold. That much I've figured out...
Public Class Form1
Private Sub BoldButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BoldButton.Click
Dim Bold As New Font(RichTextBox1.Font, FontStyle.Bold)
RichTextBox1.SelectionFont = Bold
End Sub
End Class
But I'd also like to add the ability that if the user highlights text that is already bolded, then clicks the bold button, that text will go back to 'regular' font. In other words, I'd like the 'bold' button to be able to toggle between bold and regular font.
