- Visual Basic >> ListBox selectionI have several list boxes on a form. I want to fill the first one at run
time, and based on the user's selection from that list box, fill the second
one, and so on. If there is only one item in a list box, I want the program
to select that item automatically and move on to the next list box. How do I
get the program to do this (i.e. simulate the Click event for that list box)?

- MFC >> Does MSHTML handle script?When a web page contains script codes like JavaScript or VBScript, IE
can view the page correctly as long as you don't make configurations to
disallow it.
I am wondering where does IE handles these scripts. Something out of IE
like WSH, or something inside IE? Can I do that in MSHTML?
If a page contains a piece of script that draws an image at a certain
location, can MSHTML understand that?
I mean, in the HTML DOM tree, there is only a script element;
or, there are two elements - the script element and the image element?
Thank you.

below simple looking way. My question in, is it supposed to work this way
and will it work?
LocalConn.Open()
Dim DBCommand As New System.Data.OleDb.OleDbCommand("SELECT id, name, date

- MFC >> How to filter lower case characters in an edit control?Hi to all,
I created a class that enherits from CEdit and overrode its OnChar() message
handler to intercept the entered keys and filter only those that are lower
case. It also verifies if an entered key is upper case to convert it to lower
case and filter it.
Everything works good except the conversion from upper to lower case. The
problem is that even if the OnChar() handler does convert the character to
lower case, the character is still displayed in the edit box as it was
entered, i.e. in upper case.
Please note that if I remove the line: "nChar = tolower(nChar);", the upper
case characters will be rejected and this is not what I want. I want the same
behaviour than the edit control's Lowercase property, which will convert all
characters to lowercase as they are typed into the edit box. However, this
property allows all other character types to be output.
Here's the code of the OnChar() message handler:
#define BACK_SPACE 8
void CEditLoCase::OnChar(UINT nChar, UINT nRepCnt, UINT nFlags)
{
TRACE("OnChar(): %c ; %d\n", nChar, nFlags);
// Filter all the characters in 'm_pFilter' to be processed.
nChar = tolower(nChar);
if ((nChar >= 'a' && nChar <= 'z') ||
nChar == BACK_SPACE)
{
CEdit::OnChar(nChar, nRepCnt, nFlags);
}
else
{
MessageBeep(MB_OK);
}
}
I appreciate any help and thank you in advance.

- VB Scripts >> Script to Auto Insert Images into MS FrontPage?I need a script that will examine a folder to discover all the files (jpg
images) in the folder and then create html that displays the images in my
current FrontPage web page . I can then move the images around on the page
and then save the page which will place the images in the web's images
folder.
If I do it manually using Insert/Picture etc then I get html which looks
like:
<p><img border="0" src="../../Data/LEASURE/Places/Newbury/DSC01160.JPG"
width="480" height="640">
I am puzzled that the drive and highest level folder which contains the
image is not shown.
I have only a little experience of VB and none of using VBA in FrontPage (if
VBA CAN be used in FrontPage)
any thoughts?

In Microsoft Knowledge Base Article - 297289 - a method

I seems to me that will be safer and easier to a add

all mailboxes and folders have been moved/replicated I
can just demote the first/old server...

Visual Basic >> COMM and I

Someone please point me to where I can find some sample code or
enlightenment to do Serial COMM without the MSCOMM1 component (using APIs
etc.).
Would like the ONCOMM event type capability rather than polling.

You don't like MSComm? I'm not sure of the specifics, but here's a sample
that allows....
Serial Comms with Windows API

...not sure what events it supports, though.

Visual Basic >> COMM and I
Just trying to avoid the form.
The example you cited is OK, but does not have anything like ONCOMM.
Another one I found was ARCCOMM. It additionally uses API timers.

Too much fun!

Visual Basic >> COMM and I
Hi,
I have tons of example code in my book (see below).
However, the short of it is:
Set .RThreshold = 1 'this enables OnComm events
Then, in the OnComm event:
append newly received data to a buffer and process that buffer for the data
that you need -- if there is more in the buffer than you need for the
specific job at hand, retain that extra data so that the next OnComm event
can append newly received data -- so that none is lost between calls. Do
not assume that any specific number of characters will be delivered for each
OnComm receive event.

- VB Scripts >> SQL constraint rule probelmHi there,
I'm having a hard time automatically editing some users to my SQL DB.
I established it is because the surname of the people I am adding
contains an " ' ", eg surname = O'Connel
What I am sending SQL looks like:
sQLUpdateString = "UPDATE Users SET " & updateString & _
" WHERE (UserName='" & userName & "')"
conWrite.Execute(sQLUpdateString)
My script generates updateString automatically and in the case where
it updates the users full name;
updateString = FullName='John O'Connel'
In this case userName = "JohnO"
This normally works fine, (I can update all the other users in my DB
this way), however in cases like this where the surname includes the "
' " the full name in read in as being "John O" then an error because
the "Connel" part still remains and is invalid SQL. I am told that I
should probably use a rule or a constraint to fix this, however SQL is
not really my strong suit, so any pointers on how to go about this
would be greatly appreciated.
Thanks in advance

- MFC >> strange ShellExecute behaviourHi all
In all my MFC (and normal win32) programs ShellExecute has stopped working
and now returns SE_ERR_DDEFAIL .
I'm sure that the code used to work eg. (ShellExecute(GetSafeHwnd(), "open",
"http://www.abc.com", NULL, NULL, SW_SHOWNORMAL);)
Inter explorer is registrered to open http
ShellExecute(GetSafeHwnd(), "open", "c:\\abe.doc", NULL, NULL,
SW_SHOWNORMAL);
also fails, MS Word is associated with doc
However ShellExecute(GetSafeHwnd(), "open", "c:\\abc.mp3", NULL, NULL,
SW_SHOWNORMAL);
works, Winamp is Associated with mp3

- Visual Studio C++ >> WinInet-FtpGetFile errors 12003 and 12030(Note, this happens under both Windows XP (VC++6.0) or WinCE 4.2 (eVC++4.0
SP3), which is why I'm posting this question under both newsgroups).
I'm using FtpGetFile() repeatedly to copy a folder structure that contains
222 files (total 27Mb), of which one file is 17Mb and the rest are smaller.
The 17Mb file is one of the first (#8) to copy, and it does OK, but after
14-80 files are copied (around 18-19 Mb) I get error code 12003 from the
first file that fails, then 12030 from subsequent files. Codes in the 12000
range are not included in my message list in either environment, so I don't
know what this error means. Questions:
1. What do error codes 12003 and 12030 mean? (I can't find them in MSDN or
CE Help). What is actually failing here?
2. Is there any way to get the WinInet error messages (I've seen other Ftp
routines report 12xxx error codes) included in my XP and CE environments?
I thought maybe this was a limitation of our FTP site, but our IT group says
they can copy Gbs of data with no problem.
I tried skipping over the 17Mb file, and the other 221 files (10Mb) copy
just fine.
Then, even more mysterious, I tried copying the 17Mb file last (after the
other 221), and that works fine as well!
Any ideas? Can I depend on the workaround of copying the biggest file last
always working?
Thanks,

- MFC >> MFC and number of times COM intializedGreetings,
I was told that COM should be intialized only once in application or
once per thread. I was reading SDK samples and it says:
"CoInitialize could be called more than once in an application. The
first successful call will return NOERROR; subsequent successful calls
will return S_FALSE. Each successful nested call to CoInitialize must
be matched with a corresponding call to CoUninitialize. CoUninitialize
frees resources the COM libraries have allocated and unloads the
libraries themselves. "
I have a working MFC based application which intializes COM only once
and it works great. So my conclusion is that it can be done multiple
times too. That is, both approaches are correct. Please, if someone
can verify that if both approaches are correct. Thanks.

- MFC >> Authentification from flash deviceGreetings!
I want to create GINA module, which will replace Microsoft Gina dll.
The main purpose is to enter to Operation System using flash device.
Let me describe more my idea by steps:
1) Windows is loading.
2) Gina dll module finds flash device in USB port.
3) Gina dll module reads id of flash device and uses this id in order
to enter to Windows.
At this time I wrote Gina module and it enters operation system using
password and login, but not id of flash device.
So here is my question can I come in into operation system using only
id of flash device?
So I want to read id in Gina module and enter like user (registered in
system) only using id of flash device and not to enter login and
password of this user (or only enter login).
Sorry for my terrible English.
Thank you in advance!!!
