- Visual Basic [VB] >> Mismatch between sample code and wizard skeleton/starting point ?I have a question regarding code examples in the msdn cd.
For example I will refer to the help page titled
"Using TCP Services"
As we can see, the code below is supposed to be for
a console application. My question is this: if I create
a console application with the wizard, I get a Main
sub which is inside Module1, whereas here, in the
sample, main is in a class called TcpTimeClient.
I.e. there is some implicit understanding here that one
would know how to insert this sample into the basic
template that the Console Application wizard gives
us. Is this mentioned anywhere ?
[Visual Basic]
Imports System
Imports System.Net.Sockets
Imports System.Text
Public Class TcpTimeClient
Private const portNum As Integer = 13
Private const hostName As String = "host.contoso.com"
' Entry point that delegates to C-style main Private Function.
Public Overloads Shared Sub Main()
System.Environment.ExitCode = _
Main(System.Environment.GetCommandLineArgs())
End Sub
Overloads Public Shared Function Main(args() As [String]) As Integer
Try
Dim client As New TcpClient(hostName, portNum)
Dim ns As NetworkStream = client.GetStream()
Dim bytes(1024) As Byte
Dim bytesRead As Integer = ns.Read(bytes, 0, bytes.Length)
Console.WriteLine(Encoding.ASCII.GetString(bytes, 0, bytesRead))
Catch e As Exception
Console.WriteLine(e.ToString())
End Try
client.Close()
Return 0
End Function 'Main
End Class 'TcpTimeClient

- Visual Basic >> Automatically Insert Line Labels for ErlDoes anyone know of any freeware or shareware code for inserting line

- Visual Basic >> Time Function ProblemI can get the Date function to work but the time Function returns the
following error at the line MyTime = Time
Run time error 450 Wrong number of arguments or invalid property assignment
Here is my code:
Private Sub cmdClickHere_Click()
Dim MyDate As Date
MyDate = Date
lblTime.Caption = MyDate
End Sub
'The above works and returns the correct value
Private Sub cmdClickHere2_Click()
Dim MyTime As Variant
MyTime = Time
lblTime2.Caption = MyTime
End Sub
'This Crashes
What am I doing wrong??
If I set the Dim MyTime as Time it still crashes with the following message:
Compile Error: Function or interface marked as restricted or the function
uses an automation type not supported in Visual Basic.

- Visual Basic [VB] >> Newbie Keypress QuestionDoes anyone know how to remove keypress events at form level before
they are passed onto individual controls?
For example I have a text box in my form. I set keypreview to true.
In VB 6 when I received the form_Keypress I would set the keyascii =
0. This way the text box didn't get the keypress. Is there a way to
do the same thing in vbDotNet?
TIA

- Visual Studio C++ >> exception won't catchI have an MFC application that runs off a network drive. It uses an
Oracle database, and the server is also on the network. The problem I'm
having is that if a workstation loses connection to the network during a
work session, the application will crash when trying to save data back
to the database. "Crash" being that the app simply terminates and goes
back to Windows desktop.
The data save code is wrapped within try / catch blocks. If I run the
application locally from my C drive, the exception is caught and handled
gracefully. But when running from the network, the catch block isn't
being called. I know this because there is a MessageBox that should
notify the user of a problem, and it doesn't come up.
So my question is, why does this happen? And what's the most elegant way
to get around it? If I can't get the catch to execute on failure, then
I'll need another method of knowing that the LAN is present before
trying to save.
Thanks for any ideas.

Visual Studio C++ >> Seeking opinions of best practice on splitter windows
Hello
When having a splitter window, i.e. a window that is about 5 pixels wide and
goes between the left-hand treeview and the right hand control, be it mdi
client window or listview or whatever, is it generally preferred practice to
have the left and right windows resize as the user is dragging the splitter
window, or to wait until the splitter window is dropped.
I notice that most Microsoft applications (e.g. Windows Explorer, Outlook
Express) go for the former, however it seems Visual Studio .NET adopts the
latter strategy.
I've coded my application so that it works like Visual Studio .NET. However
I can't make the splitter window adopt that transparent-gray crosshatch
pattern when it is being dragged, anybody know off-hand what the background
needs setting to to make it like that?
And also, which is the 'best-practice' method, or doesn't it generally
matter either way?

There is a system setting (desktop properties): Show window contents while
dragging. You should respect this setting and do the appropriate
painting/update. For the second problem you can take a look at the WTL's
CSplitterWindow. They use CreatePatternBrush with a gray bitmap and then
PatBlt with PATINVERT.

Oh yes, there is - that's good to know. It appears to be a numeric value in
a string key though - is this normal / to be expected? Might it change in a
future version of windows?

If you worry about future windows versions you can check for success and if
it fails
use your own setting.

- MFC >> Multithreading, Converting a Byte Array to a Hex String, Simultaneously..So.. my problema: I'm reading in a massive amount of data into a BYTE
array buffer (size 64096 bytes, and about 1MB every 5 seconds) and
writing to a file. I want to grab the info, translate it into hex, and
spit it back out on the screen to display what I am receiving. So far
I have a thread doing the receiving and writing to file, and another
thread which is supposed to be translating and spitting out to a
multiline edit box.
This is probably not a good way to do it, and I was wondering if anyone
knew a better way?

- VB Scripts >> Variables from one script to anotherHi...
I posted this before, but probably didn't explain my self well...
I need to have a script that declares and sets a value for some vb
variables, and want to have the value in these variables available in other
script...
Here is what I do :
I have a master script that calls other scripts...
1st script called from master script, it declares and sets values for some
variables ...
ex : Public appver1
appver1 = "V9_4_2"
2nd script called from master script would use the variables set in 1st
script to do execute actions with it...
ex : WshEnv("Var1") = appver1
How can this be done ...
The value is "appver1" is not necessary outside of the vb environment...
Reason is that 1st script will be modified by a lot of people, but don't
want them to modify other script...
Thanks very much !!!

- MFC >> Message which is called everytime a CFormView is createdHallo,
I have a program with a CSplitterWnd which divides 2 CFormViews.
See link: http://wwwstud.fh-zwickau.de/~pafe/geb/1.jpg
When I start the program the ListBox (CListView) on the right side
gets filled in the method OnInitialUpdate().
When I navigate through the tree then the views on the right side are
replaced.
When I come back to the element, that displays the form with the
List-Box, my ListBox is not filled with the data I provide in
OnInitialUpdate.
See link: http://wwwstud.fh-zwickau.de/~pafe/geb/2.jpg
Now my question is:
Where do I have to put the code (what message do I have to catch) to
get the ListBox filled everytime I select the corresponding
tree-element.

- MFC >> Tooltip causes an ASSERT() in a child dialog boxHello experts,
I already posted about my problem a couple of days ago, but it's not
solved yet and I have some more details about it.
Using MS VC 6.0 and Vista.
I create a CTabCtrl control in a dialog box. For each tab, a child
dialog box contains a bunch of controls (CEdit, CComboBox...). I can
display tooltips for each control, no problem.
The problem is that when the cursor (I mean the mouse) leaves a
control, if it enters the tooltip area, I get an ASSERT() warning:
In WinCore.cpp
void CWnd::AssertValid() const
{
...
// should be a normal window
ASSERT(::IsWindow(m_hWnd));
...
}
This occurs only when the dialog boxes displayed in the tabs are CHILD
dialog boxes. If I choose "Overlapped" or "Popup", it works (but I
need a child dialog box).
What should I do to avoid this problem?

- Visual Basic [VB] >> Class controling form settingsI am wondering if it is possible to make something like the following work:
Public Class myTestSettings
Public Property onTop() As Boolean
Get
Return Form1.CheckBox1.Checked
End Get
Set(ByVal Value As Boolean)
Form1.CheckBox1.Checked = Value
End Set
End Property
End Class
Second question: if it is possible, is it advisable?
I am wanting to serialize this information to an XML file. I'm exploring
this as a possibly better way to accomplish this.
Thanks in advance,
Matthew

- Visual Basic >> API calls and &H1, &H2, &H4, &H8, ..., &H10, ..., H40000, ....Okay, I came into VB without *ever* learning about the hexadecimal notation.
What do the following mean and what decimal numbers do they translate to?
&H10 (is this equal to 16?)
&H400 (is this equal to 256?)
If they are, why do I use these in API calls in lieu of 16 and 256?
Thank you ever so much!

- Visual Basic [VB] >> Using VB 6.0 Interface in vb.net causes a problemHi,
I have an interface in vb 6.0. It has a property set member, which takes a
parameter by reference. When I try to implement this interface in my vb.net
project it gives me an error saying that "cannot implement property set
because there is no matching property on interface". I think .NET does not
allow parameter to be passed ByRef in property statements.
here is my property set statement in vb 6.0 interface called IName
Property Set Name(ByRef objName as object)
End Property
VB.NET code looks like this
Public WriteOnly Property Name() as System.IntPtr implements IName.Name
Set (ByVal value as System.IntPtr)
end set
End Property
There is an underline below IName.Name. When I put my mouse over it then it
says "Cannot implement IName.Name because there is no matching property on
Interface IName". I tried changing the System.IntPtr to System.Object but it
gives the same result. I cannot change vb 6.0 interface to accept parameter
ByVal instead of ByRef because then, I have to change all other existing
components that already are implementing this interface.
Your help is appreciated.
Thanks

- Visual Basic >> PDW Msg "...already been added..."When packaging my project, I am asked to "choose the folder where your
package will be assembled." I click the "New Folder" icon and make a folder
and select next. There is a processing delay (only 550MHz machine) and the
drive rattles, then I am prompted with "Afile with this name has already
been added to the list of files." You only have the choice to click OK.
Does anyone know what causes this message?
Regards,
Jim
