- 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

- 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.

- MFC >> Max Text for CEdit ?Hi guys,
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
source from a web page that can easily be viewed in Notepad.
What's going on ? Can I fix it ?
Thanks,

- MFC >> Remote Desktop does not show system tray icon.My program is a service that runs on Windows Server 2003. The program displays a system tray icon
that seems to work fine when viewed from the PC's monitor. However, if I access the PC remotely
using Remote Desktop the icon does not appear. Many other icons appear, but not mine.
Using task manager, my program is running "SYSTEM".
NOTE: My program already handles TaskbarCreated for the case where explorer crashes.
Any ideas?

- 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?

- 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 >> 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

hi, anyone know how to retrieve date from mysql database? i am using odbc
connection. which reader.getXXX shall I use? for example, my date in mysql is
2005-04-01. i have tried using reader.getstring, reader.getdate but all still

Visual Basic [VB] >> mysql date format
Hi,
If that fails, try a simple Reader.GetValue() and do a cast to DateTime
from VB.NET code.
Or, use the official MySQL .NET provider (which involves no ODBC and is
very fast).
Regards,
-Adam.

Visual Basic [VB] >> mysql date format
Hi, Adam.
Thanks for the info on getvalue. But the result from it was a string field
value of "dd". Not "2004-04-16".
I am not using ADO as I am using DSN to perform database connection. this is
to enable the user to switch database easily by just switching the server in
DSN. Hope to hear any suggestion/solution.

Visual Basic [VB] >> mysql date format
Hi, found out that the reader is used twice and it was giving the previous
search info. changed to a new reader and the problem resolved. thanks. but
funny thing is that the reader has been closed, dbconnect also closed. after
that only the reader is reopen n search again n this problem happened. hence
i have no choice but to change by creating a new reader.
thanks for your help.

- 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.

- MFC >> mimic cin abilityI am connecting with a hardware device that sends data
via keyboard emulation. That is it sends the data as if
it were typed on the keyboard. So I wrote a shell that
used cin to get those input values. Now I am trying to
port my text based system to a dialog so it can be user
friendly.
So I want to have an edit box that has the cursor put
there. I know you can use GetDlgItemText to get text
from an edit box, but I don't know of anyway to make the
GetDlgItemText wait until a new line character like cin
does? I have also tried
CWnd* pntr=GetDlgItem(id); to see if there are any
particular methods available to you that way that would
help but I couldn't figure it out. Anybody know how to
do this one?
I also have not been able to find a method to allow me to
make the edit box the focus. the SetFocus returns a
pointer but doesn't take an id to say what is being
focused.
Thanks in advance for answering the newbie's questions.

- MFC >> 2 "type" problems...Hi,
(Follow up to microsoft.publicisa.sdk-dev)
I'm under VC++ 5.0 and try to use functions from ISA SDK.
1)I wonder how could I fill the WCHAR psz[100] with a CString content ?
Here is the code:
--------------------
WCHAR psz[100];
wcscpy(psz,L"MyString"); //this works
---------------------
But, I need to have MyString come from a CString
2)This code always return values <=255.
long l = fpcDestinationSet->Count;
ie: If I have 350 elements, the long l is : 94 (350%256)
even if I try the C++ way :
long count;
fpcDestinationSet->get_Count(&count);
printf("Destination Set : %s count : %ld\n", (char*)
fpcDestinationSet->Name,count);
the "Count" (get_Count() method for DestinationSet is here :

- Visual Basic [VB] >> Flexibility vs ReliabilityMy co-worker and I are debating Flexibility vs. Reliability.
For example this method is highly flexible:
Public Shared Function GetList(ByVal whereClause As String) As String
strSQL = "SELECT field1,field2,field3,field4,field5 FROM table1 "
If whereClause <> String.Empty Then
strSQL &= "WHERE " & whereClause
End If
Return strSQL
End Function
My co-worker agress that it is flexible but would prefer to use more
reliable techniques like Overloading and Strong Typing of parameters.
Public Shared Function GetList(ByVal field1Value As String, ByVal
field2Value As Integer) As String
strSQL = "SELECT field1,field2,field3,field4,field5 FROM table1 "
strSQL &= "WHERE field1='" & field1Value & "' AND field2=" &
field2Value
Return strSQL
End Function
My argument is that you can't predict every possible combination of field
values and arguments so the number of where clauses and overloaded methods
would grow to ridiculous proportions.
Have other people faced this issue? If so what did you think about it?
Appreciate any insights and experiences.
Thanks!

- 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
