- 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 >> Dr Watson errorI have a VB6 program that receives data using socket and save the data to a
SQL Server 2000 database.
It has Windows 2000 SP4 with all hot patches in it. It has 2 gig of RAM.
The program had been running for years with no problem, but for the last 3
days it had died exactly at 3 AM. No error on the screen, but there is Dr.
Watson error (it is in drwtsn32.log).
The error in drwtsn32.log is:
Exception number: c0000005 (access violation) --> this is on this VB
program.
I do not know how to read Dr Watson log, but the "Raw Stack Dump" contains
c:\winnt\system32\comsvcs.dll.
I searched on the internet and found that there was an Access Violation
error with comsvcs.dll, and the fix is to install the latest Windows
patches, which we already did. We also increased the memory from 1 gig RAM
to 2 gig. The program still happens.
There is no scheduled task running at 3 AM.
Does anybody know how to read Dr Watson log ?
How can I fix this problem ?
Thank you very much.

- 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!

- 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.

- Visual Basic >> Integration with Word, can this be done?Here is what I have to accomplish, and I want to know if this can be done,
and pointers on how can this be done.
1) I need to start a new Word document using a template provided by the
customer. The customer will provide different templates, and my code would
know wish template to invoke. The question is what methodology do I use to
start the new Word doc?
2) At the end when the user saves the document, I need to send a copy of
this new created document by email to a destination. The destination may
change, and the settings could be saved in a INI file (TBD). My question is
can I override the SAVE button in Word, or provide a special button on the
toolbar to be pressed when done. Don't know what to do ????
Any tips/pointers would be appreciated. Thanks in advance for your reply.

- 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.

- 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

Visual Basic >> Using timers
Hello,
1.
Is there any 'optimal' number of timers can be used on one form?
2.
Which design will be more efficient:
A. using one timer and combine different events using If... Then
statements.
Because each event requires different time interval change timer
intervals for each event will be included in the code
or
B.
For each event use different timer with preset time interval
Your thoughts please,
Jack

Visual Basic >> Using timers
I have always run multiple timers in this situation. Name the timers so
that the timer_Elapsed events are obvious. This will make you code more
readable.

Visual Basic >> Using timers
What are you trying to do?
Option:
One timer with a low interval (1 second maybe) and have the timer event
check for how much time has passed and react accordingly. Then your timer
event can trigger several events based on passed time.
Remember timer events are low priority events with the system and instead of
checking for a time being reached you should check for a time being
passed...

Visual Basic >> Using timers
Thank you.
What I am worrying about is that my form has already 15 timers on it and I
am in need to add some more.
Not all the timers are active at the same time of course, but one or two.
I do not want to have big overhead, or the code became too 'heavy'.

Visual Basic >> Using timers
Again, I ask, what are you trying to do? By explaining what you ware doing
you may get alternate methods that will work better. When you ask a
specific question you get specific answers - as we don't how or why things
are being used...
Like, 15 timers on a form, to me, seems very excessive. I have probably
never used more than 3.....

Visual Basic >> Using timers
No need to get offended. If you are, I apologize.
I have just tried to answer your question.
You asked me what I am trying to do and I explained.
Each timer has specific task as shown. At most only one or two timers are
active at the same time.
What I am trying to find is how that timers are weighting on my code?
Is there a better approach to reduce number of timers and cumulate more code
inside them?
It was my original question, btw,

Using less timers would be better. No matter how many timers you
use, you can only execute in one routine at a time anyway....

Visual Basic >> Using timers
OK..
You really haven't provided enough information on coming up with an
alternate solution. By the sound of the complexity of your application I'm
not sure you could. What's hard to tell is the why. Like why does running
a script require a timer or why does finding a window need a timer.
I guess I stand by my original statement that a single timer that monitors
all the events is the way to go. Also, its hard to tell if you even need
everything on timers.
Maybe what you could do is start consolidating timers that perform a common
function like; Recording, playback, redirect. See how this works for you
and keep moving in the direction of removing timers and not adding new
ones...
Also, I guess it would be nice to try and understand 'why so many things
need times'

Visual Basic >> Using timers
Even though with one timer, still none will work
with the intervals you expect. Because VB can do one thing
at a time, and by the time you expect it to run your function
at the interval you set, it will be busy doing the first function.
You have to run things in sequence rather than by timer intervals.
And don't expect it to run things for you in intervals of 250 or 500,
because it would take that long to run your first function.
Yes timers do run in the background, but will not function
if you have it busy doing something else.
Use one timer.
Set a long variable to count time, then call functions
when the variable reaches time desired.
'Example:
Dim T500 As Long, T750 As Long, T1000 As Long, T1250 As Long
Private Sub Form_Load()
Timer1.Interval = 250
End Sub
Private Sub Timer1_Timer()
T500 = T500 + 1
If T500 = 2 Then
T500 = 0
Call theFunction500
End If
T750 = T750 + 1
If T750 = 3 Then
T750 = 0
Call theFunction750
End If
T1000 = T1000 + 1
If T1000 = 4 Then
T1000 = 0
Call theFunction1000
End If
End Sub
Public Sub theFunction500()
MsgBox "500"
End Sub
Public Sub theFunction750()
MsgBox "750"
End Sub
Public Sub theFunction1000()
MsgBox "1000"
End Sub

- Mcse >> OT <RANT>Well. After several days of escaping the Borg-like agency which is
incorporating our IT dept, they finally managed to assimilate my pc. It
was hastily reimaged, and with the knowledge I work in the IT dept, they
decided I was knowledgable enough to install my own programs. So they
therefor proceeded to wipe my pc, install XP, and throw it at me,
expecting me to be able to carry on with my IT duties as normal, without
so much as my email account set up.
Finally, after spending all day reconfiguring my pc to my liking, it's
up and running, and I'm back at full force. I'm still not impressed with
the set up, but at least I still have admin rights (courtesy of myself),
while other users are completely locked down.
And I have to admit, it was extremely funny to hear that they ran a
script automatically shutting pc's off when the user logged in without
"their" virus scanner. Resistance is futile.

- Visual Studio C++ >> Namespaces Managed C++Hello,
can I avoid to dump everything in a namespace somehow? I'm trying to make
my class serializable as such:
// Units.h
#pragma once
#using <System.xml.dll>
#using <mscorlib.dll>
using namespace System::Xml::Serialization;
public __gc class Metric {
public:
Metric();
System::String* areaUnit;
};
Do I really have to dump everything in System::Xml::Serialization into
globabl namespace like this? I think it is bad practice to do so in header
files, at least it is with C++.

- Visual Basic >> Problem refreshing recordsetHello -
I am trying to refresh records after someone adds a new record. For some
reason, it isn't returning the last record (the one added). The stored
procedure, when I run it in Sql Server returns exactly what it's supposed to
return. I am therefore assuming the problem is with my VB code.
Can anyone see what may be causing this?
Private Sub FormRefresh()

- Visual Basic >> buy more cheaper runescape gold on www.cheap-runescape-gold.comWell for most it is a method of playing the game and working out how
to make money by developing skills that can earn good amounts of
Runescape money in comparison to the time invested. For others they
have developed a keen sense of the Runescape markets and managed to
provide a service of buying and selling major raw and processed
materials that are in high demand and supply. This means of making
Runescape gold is referred to as merchanting and loads of information
about how to go about earning gold in this way can be found in free
Runescape gold guides that are on many Runescape fan sites and forums.
Even with the availability of free Runescape gold guides there are
also many Runescape gold guides for sale on the internet, though from
my experience none are really worth the money if you have been playing
for a couple of months and have reviewed a few of the free guides to
making Runescape gold on Runescape fan sites and forums.

I have an MDI application. When the user selects File/Exit, the following

- MFC >> Saturating message queue?I was interested in timing how long it took for a parent and child thread to
exchange a series of window messages. I thought I would start with the Frame
and View in the main thread of a doc/view sdi app for simplicity.
I set up a menu item to initiate a loop. Then the Frame and View exchange a
token until the token is incremented to a certain value. However, it hangs
if I use a token value of more than 20. Am I doing something wrong? Is
"SendMessageToDescendants" an inappropriate choice? Is the message queue
"saturating"? ... which would seem odd since the app is using "SendMessage"
rather than "PostMessage"?
// MainFrame handles menu command to initiate
void CBbMainFrame::OnTimeMessaging()
{
SendMessageToDescendants(UWM_BB_FRAME_TO_VIEW, 1, 0);
}
// View handles message and checks token value
// 20 or less is ok, hangs with 21
LRESULT CBbView::OnBbFrameToView(WPARAM token, LPARAM)
{
TRACE1("View:FrameToView %d\n", token);
if (token == 1) {
HiResTimerStart(); // Uses QueryPerformanceCounter
}
if (token < 20) {
m_pFrame->SendMessage(UWM_BB_VIEW_TO_FRAME, token, 0);
}
else {
double elapsed = HiResTimerElapsedMillis();
CString csMsg;
csMsg.Format("20 loops Token: %d elapsed: %.3f\n", token, elapsed);
AfxMessageBox(csMsg);
}
return 0;
}
// Frame handles message, increments token, and sends another message
LRESULT CBbMainFrame::OnBbViewToFrame(WPARAM token, LPARAM)
{
TRACE1("Frame:ViewToFrame Token: %d\n", token);
SendMessageToDescendants(UWM_BB_FRAME_TO_VIEW, (token+1), 0);
return 0;
