WM_COPYDATA is the easiest way to do this, I believe. Not sure how you'd do that in VB.NET, but I'm certain you can.

My Project has a requirement of storing Image and Text data in Access Database. I am using Vb.net for coding.
According to me, This requirement can be fullfilled using binary files. But i am not able to figure out how to do it.
The requiremnt is to accept data in RichTextBox(Text and Images) and convert it to binary file and store it to DB(Access). and Vice Versa.
Can any body help me regarding this...
Any links berifing the matter or any article
Plz i need help...

hey, I am C# developper, but i think my code might be useful since we are both using .NET framework.
do the following.
Check if file exist first by using the File class.if exists then do this
byte[] Imagespace = File.ReadAllBytes(strPath);
strpath is the full path of the photo.
you can then send to stored procedure or do whatever you want once you have the photo in Imagespace variable.
I wish my code would be useful.

Hi thankx for the help rabih.
Any how i have fullfilled the reqirement in a different and simple way. As the data is inserted in RichTextBox i accessed the data in RTF format from RTBox and stored in database. And while retrieving i can assign the data to RTBox.Rtf. It will convert the Text and Images and will display them.
Simple isnt it...

Hello
How can I make the IDE show tool tips for the properties of my own objects? I know it can be done but am not sure where to look.
Many Thanks

Take a tool tip component and place it on the form.
Go to Mouseover event of ur object and add this text...
ToolTip1.setToolTip(ObjectName(EX:Button1),"ToolTipText"(Ex:"New"))

Thanks for the reply, but its not quite what I'm after, I may have phrased the question wrong.
The kind of tool tips I am after are when I am using my object in code and the intellisense pops up. When I select a particular property for my object I would like some text to appear detialing what the property does. Like when you are using a text box and you type TextBox1.Text and a tool tip pops up telling meabout the Text property.
Many Thanks

hi everyone,
i have created a hashtable that will create 5 random and unique numbers, and have copied it to an array. i now need to retrieve the stored values from the array to individual labels (label1.Text, labe12.text). your help is appreciated.
here is my code:
Dim hash As New Hashtable
Dim RandNum As Integer
Dim targetArray() As DictionaryEntry
For I As Integer = 1 To 5
Do
RandNum = Convert.ToInt32(Rnd() * 15)
Loop While hash.Contains(RandNum)
hash.Add(RandNum, Nothing)
Next
ReDim targetArray(hash.Count - 1)
hash.CopyTo(targetArray, 0)
label.text = targetArray(1) 'i am getting an error stating i cannot
'convert a dictionary entry to string.

You can get an array of the keys or values by hash.Keys and ( I think ) hash.Values.
As you're using .NET 1.1, you need to call ToString, as the contents of your hashtable is an object.

The same way as any other database, just use the specific provider classes for Oracle.
You get a connection to oracle (OracleConnection?). You create a command (OracleCommand) and you give it the details of the SQL you want to run and any parameters and the connection you opened earlier. Then you call ExecuteScalar() to get your value back.
