The date/time in any database doesn't have a format. It's stored as a serial number value. Only when the data is displayed in a table view in Access does it get formatted. You have to do the same thing in your code. If you've created your own columns, it's pretty easy, click[^].

Hi all,
which toll/add-in (like VBDOX or doxygen) do you use to comment your source code and generate the documentation for your VB2005 projects?

Thanks in advance,
Marc Soleda

You might want to take a look at the VSdocman 3.0 addin for Visual Studio. It parses your source code and generates MSDN style documentation, that is completely customisable....

There web address is: www.helixsoft.com[^]

Try openning the two files in binary mode (I think) to read them byte by byte and compare. A coworker made image format converters using this method.

What is it that you want to do if the data is/not equal?

Try looking up "filestream walkthrough" in your help menu. (I use VB.Net 2003) It gives an example on how to read files.... Or GOOGLE it. "filestream" is the method you'll need to work with I think.

Hope it helps.... Happy Hunting.....

I have an array called marr() its initialized with no parms
and inside a for loop on vb6 i have t his syntax

count = count + 1
ReDim Preserve marr(0 to count)
marr(count) = var20

my problem is that i dont know how to write a .net 2003 version
of that marr(0 to count) i have tried lookin online but havent
found an answer... i appreciate any help... thanx in advance...

Some times I bite way more than I can chew ... thats why i always buy cheese nips to keep me munching from dusk until dawn

Instead of Redim Preserve you could use Array.Resize(marr, count)

ReDim Preserve still exists, but you've used the old VB6 syntax. All arrays in the .NET Framework start with index 0, or 0-based, so it's unnecessary to specify it in the new dimension parameter. Just use:

ReDim Preserve marr(count)

If i have the following properties enabled....

Form autosize = True
Form maxsize = True
Form minsize = True

Does this mean that my Form will goto the maxsize of the users screensize and not beyond.?

No, you have to set the WindowState to Full.

The Form.MaximumSize and Form.MinimumSize properties do not accept a Boolean value, so that code has no meaning.

If you want your form to fill the screen all you have to do is set its WindowState property to Maximized:

myForm.WindowState = WindowState.Maximized

Hi,
I would like to automate powerpoint using visual basic. So for that i have created an add-in and that add-in will keep track of the events that is happening in the slide show. But when a click a slide i could able to keep track of the slide change only. Even an animation can occur when the user clicks. So an animation can occur either automatically or through events. If it is through events it can be either mouse or keyboard events. If it is using mouse event then the user can click to go to next animation or either choose next or previous my right clicking the during the slide show. If it is through key board then user may press any key key to change or previous slide. One thing is very clear that if the user choses any of the way the event that is going to appear is same. So how to keep track of this event? Or Which event will occur when the user does either? And how to the get the information about that event?

In otherwords which event will be posted when the user right clicks and choses next or previous? PLz someone help me in this.............................. If i could get the animation change then i have reflect the change in the client side. So that i wil take care. First i would like to know which event will occur or how to capture the mouse and aeyboard event?

Note : i am using visual basic

First, have you done any database work at all from VB.NET?

You'd have to create a table in the database, if you don't already have one to put this information, with, at a minimum, a column defined as Text with a specific length, say 50 characters. In your code you have to create an OleDbConnection object and a OleDbCommand object. This command object needs an SQL statement to add things to the column in your table. Then you create a OleDbParameter object:

Dim conn As New OleDbConnection(connectionString)
Dim comm As New OleDbCommand("INSERT INTO tableName (columnName) VALUES (?)", conn)
comm.Parameters.Add("@p1", OleDbType.VarChar, 50).Value = stringValueToAdd
conn.Open()
comm.ExecuteNonQuery()
conn.Dispose()

This is a very simplified example of one way to do this. I, in no way, imply that this will work with your code.

RegisterHotKey

I'm using RegisterHotKey, but how do I register multiple keys and make them do different operations?

    Public Declare Function RegisterHotKey Lib "user32" (ByVal hWnd As IntPtr, ByVal id As Integer, _<br />
                                                          ByVal fsModifiers As Integer, ByVal vk As Integer) _<br />
                                                          As Integer<br />
    Public Declare Function UnregisterHotKey Lib "user32" (ByVal hWnd As IntPtr, ByVal id As Integer) As Integer<br />
<br />
    Public Const WM_HOTKEY As Integer = &H312<br />
<br />
    Public Enum Modifiers<br />
        MOD_ALT = &H1<br />
        MOD_CONTROL = &H2<br />
        MOD_SHIFT = &H4<br />
        MOD_WIN = &H8<br />
    End Enum<br />

    Protected Overrides Sub WndProc(ByRef m As System.Windows.Forms.Message)<br />
<br />
        If m.Msg = WM_HOTKEY Then<br />
            MsgBox("Hot key pressed")<br />
        End If<br />
<br />
        MyBase.WndProc(m)<br />
    End Sub

Then I register the key with something like RegisterHotKey(Me.Handle, 101, Modifiers.MOD_CONTROL, Keys.L)

Re: RegisterHotKey

Dave Kreskowiak2-Jan-07 4:56

As described in the docs for WM_HOTKEY[^], you look at the LPARAM of the message to see which keys were pressed. You can then branch based that to each routine you wanted to do.
