- MFC >> how to use invalidate and validateI am using DrawRectangle and SetPixel and some other drawing functions over
an image displayed in the background. I'm wondering what exactly I should be
doing to make sure that when my application regains focus that things were
like they were when focus was lost. I'm not quite sure what the Validate
functions do, which is part of the problem.

- VB Scripts >> Replacing Shut Down...I think I may have originally mis-posted this message to the wrong newgroup
Does anyone know if I could replace the "Shut Down..." button in the Start menu with a my own shortcut that points to a VBScript that will restart the computer? If so, how do I do it?
What I need to do is prevent the user from being able to shutdown the PC. With the NoClose option, the user also loses the capability to restart the PC which we would like them to have. I have to provide a script that will give them that option. I would like to have the "Shut Down..." button run my script
Thanks in advance

- Visual Studio C++ >> Is overriding a function of a library in accordance with C++ standard?Is overriding a function of a library in accordance with C++ standard?
The following code is passed by the VS 2005 and Dev C++.
#include <cstdlib>
#include <iostream>
using namespace std;
size_t strlen(const char* p)
{
return 0;
} // !!! Note this !!! The standard library function strlen is
deliberately overriden.
int main(int argc, char *argv[])
{
system("PAUSE");
return EXIT_SUCCESS;
}
There is even no warning after compiling the code. In front of the
fact, I have to make a guess that all the C++ compilers are conformed
to the following rules:
1) The compiler first compiles all the source file included in the
project into object files;
2) At link time, the compiler first searches the object files for all
the unresolved symbols; if it fails to find some symbols, then the
compiler will search the libraries which are included in the project to
find the symbols.
3) If the object files containes a symbol, then the symbols that have
the same name in the libraries will be ignored.
Am I correct?
Any help will be appreciated. Many thanks in advance.

- Visual Basic [VB] >> User Control Property Defaults QuestionI created a user control. It has a text box in it. Everything works
fine. However, when I place my control on a form, many of the
properties are already in bold. This is supposed to mean that
something other than the default was chosen for those properties. But
that is not correct. The properties are set to their "default" value.
Example of my code for one property:
<Browsable(True),
DefaultValue(System.Windows.Forms.BorderStyle.Fixed3D),
Description("Indicates whether the EnhancedTextBox will have a
border.")> _
Public Overloads Property BorderStyle() As
System.Windows.Forms.BorderStyle
Get
Return TextBox1.BorderStyle
End Get
Set(ByVal value As System.Windows.Forms.BorderStyle)
TextBox1.BorderStyle = value
End Set
End Property
I have my "DefaultValue" set for this property. And when I place a
new instance of this control on a form, the BorderStyle is Fixed3D,
but it shows in the Properties Window in bold. Why? And how do I fix
this? This property is also in the Designer code of the form I placed
the control on and it should not be. I thought that default values of
properties are not supposed to be in the Designer code.

- Visual Basic >> Unloading an application from the system tray menuI use a system tray icon for my application, that found from:
http://www.mvps.org/vbnet/code/subclass/shellnotifybasic.htm
In this system tray program if we want to close the application
from the system tray menu we must use the :
Call PostMessage(Form1.hWnd, WM_CLOSE, 0&, ByVal 0&)
This WM_CLOSE message is equal to vbFormControlMenu in
a QueryUnload or Unload Event.
But in my application I have at the QueryUnload Event :
If UnloadMode = vbFormControlMenu Then
Cancel = True
Form1.WindowState = vbMinimized
Exit Sub
End If
The article of the above system tray icon program, says that
we have a GPF if we try to close the application with an
Unload.Me Statement. I tried this and I didnt saw any GPF...
Thereby I use the Unload.Me Statement to close my application
from the system tray icon's menu, because the WM_CLOSE
message, simply minimize the application.
If I have two or three open Forms and the user press "Exit"
from the system tray, then i have to put in the code the :
Dim n As Integer
For n = Forms.count To 1 Step -1
Unload Forms(n - 1)
Next
and then when I have a modal Form opened after this code,
I have to write at the after the "Form3.Show vbModal" clause,
the :
If Forms.count = 0 Then Exit Sub
My question is if with this way all the forms unloaded from
the memory, or there is another way to exit from my application
from the system tray icon menu.

- MFC >> Windows/MFC bug with TOOLTIPS??I'm not sure if this bug is in MFC or with the tooltip common control, but
I have an MFC application with tooltips enabled for the toolbar. I'm "owner
drawing" the tooltips, but I'm having this problem:
Button1 Button2
the tooltip for Button1 is "AAAAAA"
the tooltip for Button2 is "ZZZZZZZ"
On a "slower" machine (1.6ghz), I mouse over button1 and "AAAAAA" pops up
just fine, then I mouse over button2 and I see "AAAAAA" moved over button2
for a second before it updates itself to "ZZZZZZZ". What I mean, is that I
see the old tooltip moved over to the new location flash before the tooltip
updates.
It even happens on standard tooltips.
Seems like something weird, because if I put a "Sleep(100);" in the WM_PAINT
handler, I can see the window moved over (with the old tooltip intact). Like
windows is caching something. Normally if you put a Sleep(100) in the
WM_PAINT handler and the window is hidden/shown like a tooltip, I would
expect the window underneath to show through, but it doesn't in this case...
the window is shown like its being painted somehow.
I've tried the normal tricks with UpdateWindow(), SetWindowRgn(),
WS_VISIBLE, etc... but I can't figure out a way around this...
Any ideas?

- Mcse >> Design ExamsI have one more exam to complete before im MCSE W2K... and
its one of the design exams. I've heard the 220 exam is
four hours long... which seems a little daunting! I asked
at my local test centre and they suggested 70-219. I dont
seem to hear much about 70-221... is that because everyone
has been put off by 70-216? Anyone out there got any
advice on the design exams for me (and any books you can
suggest would be helpfull)

- VB Scripts >> Regular Expression Replace : $1 shows up as literal.Hi There.
I have searched the news groups and cannot seem to find an answer to my
situation. Basically, I have the following function (that appears
standard across all posts):
Public Function Highlight(p_sFind, p_sSearch)
Dim RegEx
Set RegEx = New RegExp
RegEx.Pattern=p_sFind
RegEx.IgnoreCase=True
RegEx.Global=True
Highlight = RegEx.Replace(p_sSearch,"<b>$1</b>")
End Function
However, wheneven I execute it on some code, I get a literal "$1"
rather then the string I searched for.
For example, Highlight ("Harv", "Harvard Medical School") returns:
"<b>$1</b>ard Medical School" rather than "<b>Harv</b>ard Medical
School".
Does anyone have any idea what I am doing wrong. Is any server
requirements in using this tool?
Thanks

I tried pasting a lot of characters into a CEdit but it got truncated and I
couldn't type anything else in. It wasn't a huge amount of characters, just

What's going on ? Can I fix it ?

- Visual Basic [VB] >> Reliable conversion from byte() to string WITHOUT use of System.Text.EncodingThe reason I want to do so, is that I am sending to DOS and I am pretty
certain that it will not work.
Everything I've tried so far hasnt.
In my test environment (Windows to Windows) this works perfectly, but not
when sending to DOS:
Private Function bytearray2string(ByVal input As Byte()) As String
Dim output As String
output = System.Text.Encoding.Default.GetString(input)
Return output
End Function
Private Function string2bytearray(ByVal input As String) As Byte()
Dim output() As Byte
output = System.Text.Encoding.Default.GetBytes(input)
Return output
End Function
I have also tried this, to no avail in Windows:
Private Function bytearray2string2(ByVal input As Byte()) As String
Dim output As String = ""
Dim i As Integer = 0
'Dim vchar As Char
While i < input.Length
output = output & CChar(Chr(input.GetValue(i)))
i = i + 1
End While
Return (output)
End Function
Private Function string2bytearray2(ByVal input As String) As Byte()
Dim output(input.Length - 1) As Byte
Dim i As Integer = 0
For i = 0 To UBound(output)
output(i) = CByte(Asc(input.Chars(i)))
Next
Return (output)
End Function
The desired functions need to use no encoding and be able to work with
simple bytes. The values I'll be receiving wont be higher anyway.
I'd appreciate any feedback whatsoever.
regards,
J

- Visual Basic >> Controlling ProductVersionHello - In VB.NET, how do I control product version, and access it for
reporting on my splash form? This is a simple .exe solution with a project
built out of a few forms and modules, and contains a setup project.
My vbproj file contains ProductVersion = "7.10.3077" . When I report
Application.ProductVersion, its value is 1.0.1723.16260 so clearly that
comes from somewhere else. Anyway, I don't want either of these values.
I would like to set the product version to 1.1.0, and report 1.1.0.build# .
So I'm looking for advice on how to set the value, and how to access it at
runtime.
Thanks in advance -- Dick Bixler
