If you mean like a firewall does, then no. It takes driver level code to do this. Something that VB.NET, or managed code in general, is not suited for.

VB.NET, C#, ... About the only language that doesn't target the .NET Framework natively (Managed Code) is Visual C++.

Use the forms KeyPress event
also set the forms keypreview property to true
Private Sub Form1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs)
If Char.IsControl(e.KeyChar) Then
If e.KeyChar.Equals(Chr(Keys.Return)) Then
'Your Code Here
End If
End If
End Sub

HOW to I close another dialog box from another application? Sendkeys doesn't send the tab key with a modal dialog box (Yes, No, Cancel buttons displayed)... How do I do this?
Do I have to use API calls? How? I am GREEN... I've seen some samples out there, but perhaps I didn't put the code in the right place?
CONFUSED...

You could send WM_CLOSE, I suppose. That may work. I thnk that's what the shutdown process does.
What are you trying to do ?

Thanks for your prompt response. In vb net, I am trying to make another Windows application close (or respond) it's modal dialog boxes. It's a software program called "CareFacts", at my place of employment. I am an amateur programmer in vb net, but I've been able to accomplish several things, like games, sound, multiple forms, etc. Several of the modal dialogs come up, and I am trying to send code to respond to them, close them, etc.
I've been able to interact with the program, using API calls. I believe the "handle" changes when the modals come up; I'm not sure how to change the handle.
If you want to see my code, let me know, and I will send it to you..
much obliged for your attention-this program really sucks because it requires the end date for each of our clients to be updated manually... 535 plus (adds up to about 14,000 keystrokes or more), thus my trying to make this vb net program work.
thanks again...

Well, the modal form has it's own handle, and that's the form you want to send a message to.

I'm not sure how to find the handle, and I am also not sure how to change it. Can you give any advice on both? thanks!

There are C API functions you can p/invoke to go over all the active window handles. If you know the caption text of the window you want, you can find it that way.
You don't want to change the handle, nor is that possible. You want to send it a message, namely WM_CLOSE. SendMessage is the API you want to p/invoke, I think.

I have a VB.Net 2005 program.
In the program, users enter values into text boxes, and then when they go onto the next box, the text box is disabled.
I have set up a global variable to detect if the form has been on before. Is there any way, if the form has been on before, to make it reset (i.e. like the program has just been compiled again), so there are no values in the text boxes.
Really need help on this, im sure there has to be some reset command somewhere.
Cheers in advance for the help
(p.s. program is already set up with if's as validation, not arrays, so cant do it by running through arrays!)

There is no reset command, bar the InitializeComponents method. You should write one, call it initially, and call it as you need to.
If you want to reset all textboxes, then you just iterate over the controls collection, finding all textboxes.
What do you mean by 'been one before' ? If the form is being created every time, then it's a different instance of the form people are seeing.

Its done so that if the user wants to fill in the form again they can, but i want the form to be reset! I didnt know if there was a way to do this on formload, kinda reset-all!
It uses this code per input:
If txtInput1.Text.ToLower = lblLetter1.Text Then
lblLetter1.ForeColor = R
intScoreTop += 1
Else
lblLetter1.ForeColor = W
End If
txtInput1.Enabled = False
txtInput2.Enabled = True
txtInput2.Focus()

OK, like I said, to do a reset all, you need to write your own.

Hello, I'm creating a macros in Excel that allows a person to export large amounts of data from the excel page and save to html. I'm using an example from the book VBA and Macros for Microsoft Excel by Bill Jelen, Tracy Syrstad. Except I've added a custom form that allows the user to determine how many rows of data to extract per html page as well as other features so that it will work with different files of different columns and column names.
My problem is this. I have an excel field called IMAGE_URL. It contains a normal URL to a product picture on the web. Instead of letting my html pages point to that picture online, I'd rather copy the picture and save it into the same folder as my HTML files so that when I upload the pages to the web they point to the pics in the folder and not elsewhere on the web.
Does anyone have any advice? I basically need to know how to access the picture with the given link and then save it in my folder but I need to automate it within the macros code. I'm trying to use createobject() but have yet to come up with anything.
To calrify exactly what I am doing. I have several excel files with thousands of rows of data. The fileds are like
ProductID, ProductName, Brand, Description, Price, Image_URL
I've created the macros that allows me at the click of a button to send that data to html files depending on how many rows of products I want to go into an html page. Inside the excel file I have place the html tags such as 'Print #1, "" etc so all the formatting is predefined through out each html page. I just need away to save the images from the web inside the same folder instead of point to the images elsewhere on the web.

I adapted the code here[^] to do something very similar in VBScript. I was downloading an .EXE file, but the concept applies to what you're doing. Let's see, where did I put that script...
GetBinaryFile "http://sourceURL", "destinationFilePath"
Private Function NavigateToPage(objIE, url)
attempts = 0
timeout = 5000
i = 0
While attempts < 5
objIE.Navigate2 url
While (objIE.ReadyState < READYSTATE_COMPLETE) And (i < timeout)
WScript.Echo "Waiting... " & i
WScript.Sleep 100
i = i + 100
Wend
If i >= timeout Then
WScript.Echo "Retrying..."
attempts = attempts + 1
i = 0
Else
' Domain should not be blank if the page worked!
If objIE.Document.Domain <> "" Then
NavigateToPage = True
Exit Function
Else
NavigateToPage = False
Exit Function
End If
End If
Wend
NavigateToPage = False
End Function
Private Sub GetBinaryFile(uri, filepath)
Const adTypeBinary = 1
Const adSaveCreateOverWrite = 2
Const adSaveCreateNotExist = 1
Set xml = CreateObject("Microsoft.XMLHTTP")
xml.Open "GET", uri, False
WScript.Echo "Downloading " & uri & "..."
xml.Send
Set oStream = CreateObject("Adodb.Stream")
oStream.Type = adTypeBinary
oStream.Open
oStream.Write xml.responseBody
WScript.Echo "Saving to file " & filepath & "..."
oStream.SaveToFile filepath, adSaveCreateOverWrite
oStream.Close
set oStream = Nothing
Set xml = Nothing
End Sub
