create a byte() field in Access Table and put it your image with:
open c:\myImg.jpg for binary access read #1
get #1, buffer()
close #1
connection.execute "insert into MyTable (MyField) VALUES (" & buffer() & ")"

hi!
How j can find the dominant color in a bitmap?
|
|
|
|
|
Create a histogram from the color of each pixel in the image.
Don't ask me for code, I don't have any. Your best bet would be Googling for "histogram algorithm vb.net".

Hi All
I am working on ASP.NET (VB.NET) application.
I am creating some controls at runtime(A list of LinkButtons in a table).
On the click of a button i create all these controls. Now when i click on any of these controls they take me to another page. But when i click on back button and again press on any dynamic link button, it does not work properly. It seems that all these buttons have lost their event. Why? HELP!

Great! Now drop this question in the ASP.NET Forum[^] and you might get a better response. What you're asking really has nothing to do with VB.NET.

Hi!
I have an app that writes to a log file all the app's steps. I have several threads writing several times per second to the log file. The thing is that i have detected an exception with one of those writings, when i try to OPEN the log file. I use FileShare.Write so that there's no problem with writes form several threads at the same time(i thought).Did anybody experienced such a problem or is it my bug? I only write to the log in one function and i close the filestrems an the end.The code is:
Try
fs = File.Open(logPath & Format(Now(), "yyyyMMdd") & ".txt", FileMode.Append, FileAccess.Write, FileShare.Write)
fsWriter = New StreamWriter(fs)
fsWriter.WriteLine(Now & vbTab & entryString)
Catch ex As Exception
writeToErrorLog(ex.ToString)
Finally
If Not fsWriter Is Nothing Then
fsWriter.Close()
End If
If Not fs Is Nothing Then
fs.Close()
End If
End Try
Never say never

You just told us "It's broke". What's the exception message?

Hi!
In the button's handle declare a new textbox(withevents if you want or add the handlers you desire), initialize it and finally add the Control to the Form, or else the button won't show up.

dear carlos,

Ok.sorry.I was on a hurry, i was leaving for my lunch hour :P
In the handler of the button you need to declare a new textBox object and do all the stuff i wrote.Here's a simple case:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
dim myTextBox as New TextBox
myTextBox.Location = (...)
myTextBox.Size = (...)
'If you need handlers
AddHandler myTextBox.(...), AddressOf myHandlerFunction
Me.Controls.Add(myTextBox)
(...)
End Sub
That's it then you can access the textBox through the Controls collection (Me.Controls(x)).If you would like to access the textbox in another way, and because you create them dinamically, maybe you should keep them in an arrayList or hashTable.
Sorry for the last post, i really hope i was clear this time.If not, ask again.
Never say never

Hi,
I am using Webbrowser control to make a sort of custom web browser. I can browse any URLs with the Navigate method of the Webbrowser control. But when I use this method to open a saved URL shortcut, it doesn't open properly - graphics are not loaded. I saw that Webbrowser is opening not the URL contained in the URL shortcut but some other file in the Temporary Internet Files directory. I deleted temporary internet files, cleared history etc but still it seems the webbrowser generates the temporary file from the shortcut.
How can I make sure that the Navigate method opens the acutal URL contained in the shortcut ?
I hope what I ask is clear enough.

You can't send Navigate the shortcut. Since your doing this in your own browser, you'll have to open the shortcut, get the URL out of it, then use that in the Navigate method.

How can I open it (of course from within VB) to extract the URL ? TIA

Well, that's a bit of a problem. Read this[^], about half way down the page. You might be able to read the shortcut using a similar technique.
