 - VB Scripts >> Collect Item Return in diffrent order.Hello all,
 
 I'm not the best programer in the world so I was wondering if I could get a
 little help from you all. I'm using VBScript to make a WMI call to the event
 viewer on a 2003 server. The return for the query is great... Code snip.
 
 et colEvents = objWMIService.ExecQuery ("Select * from Win32_NTLogEvent
 WHERE (Logfile = 'System') AND (EventCode = '6005'or EventCode = '6008' or
 EventCode = '1074' or EventCode = '1076') AND (SourceName <> 'W3SVC')")
 
 intCount = 0
 For Each objService in ColEvents
 
 if objService.EventCode = "6005" THEN
 strboottime = objService.Timewritten
 end if
 
 if objService.EventCode = "1074" THEN
 intCount = intCount + 1
 strstoptime = objService.Timewritten
 strdiff = ( DateDiff("s", WMIDateStringToDate(strstoptime),
 WMIDateStringToDate(strboottime)) )
 intdiff = intdiff + strdiff
 WScript.Echo "Down For: " & SecondsToText(strdiff)
 
 This returns....
 
 Down For: 1 Minute, 7 Seconds
 Down For: 1 Minute, 24 Seconds
 Uptime Report For: CSCS-IT-007C
 Microsoft Windows XP Professional 5.1.2600
 Install Date: 12/06/2004 11:28:17
 Last Reboot: 01/11/2005 18:03:23
 Up For: 6 Days, 17 Hours, 45 Minutes, 9 Seconds
 Total Reboots: 2
 Total Down Time: 2 Minutes, 31 Seconds
 
 So far so good, now I want to change how far back data is collection so I
 mode the query to look for timewritten... code snip...
 
 Set dtmStartDate = CreateObject("WbemScripting.SWbemDateTime")
 DateToCheck = Date - 365
 dtmStartDate.SetVarDate DateToCheck, True
 
 Set dtmEndDate = CreateObject("WbemScripting.SWbemDateTime")
 dtmEndDate.SetVarDate Date, True
 WScript.Echo "Start Date: " & dtmStartDate & " End Date: " & dtmEndDate
 
 Set colEvents = objWMIService.ExecQuery ("Select * from Win32_NTLogEvent
 WHERE TimeWritten >= '"&dtmStartDate&"' AND Logfile = 'System' AND (EventCode
 = '6005'or EventCode = '6008' or EventCode = '1074') AND SourceName <>
 'W3SVC'")
 
 The problem I have is the output order is diffrent. Instead of DESC it now
 AESC. I have tried to add ORDER BY TimeWritten but I get an error. Any
 insite on how to change the order would be very helpfull.
 
 Thanks
 David.

 - MFC >> OT - Debug Windows EXEHi Guys,
 
 Sorry about the offtopic message.
 
 I have an old exe (16 bit). Don't have the source. I want to step throught
 the exe. I tried loading it in VS 2003 and even 4.1 but couldn't get it to
 do it.
 
 I remember doing that with exe's back in DOS days. Opening the exe in TASM
 and stepping through the exe.
 
 Does anyone know of a program that will let me do this?

 - MFC >> OnCreate of CFrameWnd based splitter pane gets called twice!!!Hi All,
 
 I have a splitter window, in which I want to have 3 panes (as vertical
 columns).
 
 My primary requirement is I want a menu inside one of the panes, i.e,
 menu should belong to the pane and not the whole window.
 
 To achieve this, I put a CFrameWnd derived class inside the pane. This
 CFrameWnd derived class has the menu I want.
 
 Now, my problem is that after I do this, the OnCreate of the FrameWnd
 is getting called twice all the time. Can anyone help me know why this
 is happening?
 
 Or even better, does anyone have an alternate solution to putting a
 menu in each pane of a splitter window?
 
 Thanks

 - Visual Basic [VB] >> printing a text file, printdocument1_printpage gets called TWICE for each page?!Ok, so this is driving me mad. For some reason, regardless of the
 value of ev.hasmorepages, the printoducment1_printpage gets called
 twice for every page. So, I print 2 pages of data on one page, with
 the second overlaying the original data. If i set ev.hasmorepages to
 false, essentially telling the printdocument to only print one page,
 it prints one page, with two pages of data, because at the end of the
 _printpage subroutine, even when ev.hasmorepages is false, it runs the
 sub once more. Any help on this would be fantastic, below is my code:
 
 Private Sub PrintDocument1_PrintPage(ByVal sender As System.Object,
 ByVal ev As System.Drawing.Printing.PrintPageEventArgs) Handles
 PrintDocument1.PrintPage
 Dim linesPerPage As Single = 0
 Dim yPos As Single = 0
 Dim count As Integer = 0
 Dim leftMargin As Single = ev.MarginBounds.Left
 Dim topMargin As Single = ev.MarginBounds.Top
 Dim line As String = Nothing
 'ev.HasMorePages = True
 ' Calculate the number of lines per page.
 linesPerPage = (ev.MarginBounds.Height /
 printFont.GetHeight(ev.Graphics)) - 1
 
 ' Print each line of the file.
 'If counterx = False Then
 While count < linesPerPage
 line = streamtoprint.ReadLine()
 If line Is Nothing Then
 Exit While
 End If
 yPos = topMargin + count *
 printFont.GetHeight(ev.Graphics)
 ev.Graphics.DrawString(line, printFont, Brushes.Black,
 leftMargin, yPos, New StringFormat())
 count += 1
 End While
 'End If
 'If counterx = False Then
 'counterx = True
 'ElseIf counterx = True Then
 'counterx = False
 'End If
 ' If more lines exist, print another page.
 If (line IsNot Nothing) Then
 ev.HasMorePages = True
 Else
 ev.HasMorePages = False
 End If
 End Sub
 
 ..........THIS IS WHAT CALLS THE PRINTPAGE....
 streamtoprint = New IO.StreamReader("C:\temp.dat")
 Try
 printFont = New Font("Times New Roman", 10)
 AddHandler PrintDocument1.PrintPage, AddressOf
 Me.PrintDocument1_PrintPage

 - Visual Basic >> passing a textbox control in parameter listHi, I have an application that has about 3 subroutines that I'd like to use in another application so I decided to move them out into a DLL. Anyway, I moved them out and I call them from the two applications and they all work fine. When I moved them out, I temporarily commented out anything to do with the user interface - basically the routines do some processing of files that sometimes takes a long time so in the original application, the routines would update a little status form
 
 What I'd like to do is popup the status form in each of the two applications and then call the subroutines in the DLL and then have the subroutine update the form. So I decided to add a simple textbox control in the subroutines' parameter list. When I go to compile the DLL I get
 
 Compile error
 Private object modules cannot be used in public object modules as parameters or return types for public procedures, as public data members, or as fields of public user defined type
 
 This is the test subroutine that gives me the compile error
 
 Public Sub test(t As Control
 t.Text = "foobar
 End Su
 
 Am I stuck, am I doing something wrong? Is there a way around it? Any other suggestion of how to do what I'd like? Thanks

 - Visual Basic >> Show previous instance?I use App.PrevInstance to assure that a second instance of my app
 cannot be started. If it's True, I display a MsgBox telling the user
 about it and then force a shutdown of the second instance.
 
 What I would like to do is quietly shutdown the second instance and
 bring the previous instance to the foreground maximized. How do I do
 that?
 
 (I'll bet this is on Randy's web site somewhere but I couldn't find
 anything.)

 - Visual Basic >> If.....Else?I have a WebBrowser control & a hidden ListBox. When the Form loads,
 the ListBox gets populated with those sites which the user has
 categorized as Restricted Sites (the ListBox actually gets populated
 with the different URLs from a text file).
 
 Now what I want is when the user types a URL in the address bar (which
 is a ComboBox), first it has to be checked whether the typed in URL
 exists in the ListBox or not. If yes, then show a MsgBox to the user
 asking hime whether he would like to proceed ahead or not (since it is
 a restricted site). If yes, take the user to the URL but if no, stay
 there itself & change the URL of the ComboBox to what it was before the
 user typed in the URL of the restricted site.
 
 For e.g. a user first visits www.yahoo.com which is not listed as a
 restricted site (though it will be checked first whether www.yahoo.com
 is listed as a restricted site or not). Next he types www.google.com,
 which is listed as a restricted site, in the address bar. When he
 presses 'Enter' on the keyboard, since www.google.com is a restricted
 site, he will be first shown a MsgBox asking whether he would like to
 proceed or not. If yes, direct the user to www.google.com but if no,
 stay there itself & change the address in the address bar to
 www.yahoo.com (since before typing www.google.com, the user was in
 www.yahoo.com).
 
 This is what I tried:
 
 Private Sub cboURL_Click(Index As Integer)
 Dim iCount
 For iCount = 0 To lstSites(0).ListCount - 1
 If (InStr(cboURL(0).Text, lstSites(0).List(iCount)) > 0) Then
 If (vbYes = MsgBox("Are you sure you want to proceed?",
 vbYesNo)) Then
 wWeb.Navigate2 cboURL(0).Text
 Else
 wWeb.Stop
 End If
 'Else
 ' wWeb.Navigate2 cboURL(0).Text
 End If
 Next
 End Sub
 
 Suppose the user types www.google.com, which is a restricted site, in
 the address bar. He is shown the MsgBox. Assume that he clicks No; so
 he stays put where he was & doesn't proceed ahead.
 
 Assume that next he enters www.yahoo.com in the address bar which is
 not a restricted site. Under such circumstances, the commented "Else"
 condition would take the user to www.yahoo.com after verifying that
 www.yahoo.com is not a restricted site BUT if that "Else" condition
 (i.e. the second "Else" condition) is not commented, then when the user
 had been shown the MsgBox asking him whether he would like to proceed
 or not after he had typed www.google.com in the address bar, then
 irrespective of whether the user clicks Yes or No in the MsgBox, he is
 still directed to www.google.com. The bottomline is there can be 3
 scenarios:
 
 1. URL typed in the address bar exists in the ListBox; show MsgBox
 a. If "Yes" is clicked in the MsgBox, let the user proceed forward to
 the restricted site (MsgBox="Yes")
 b. If "No", stay there itself & don't let the user proceed ahead.
 (MsgBox="No")
 
 2. URL typed by the user in the address bar doesn't exist in the
 ListBox; so let the user go ahead (which is as good as MsgBox="No").
 
 So on one hand, when MsgBox="No", then stay there itself but on the
 other hand, when MsgBox="No", proceed ahead. This is where I am getting
 stuck up i.e. the condition is the same (MsgBox="No") but 2 different
 statements have to be executed.
 
 Any ideas how do I overcome this problem?
 
 Thanks,

 - VB Scripts >> CDONTS strangenessI'm trying to send a mail using CDONTS with a .FROM email
 address that doesn't exist (like bob@nowhere.com), but it won't send
 the mail unless I put a valid .FROM email address (i.e. of an email
 address that exists)
 
 The mails I try to send on the Windows 2000 server are moved into the
 mailroot/Badmail folder as spam.. so this would seem to be a built-in
 spam prevention tool that CDONTS employs.
 
 This would be fine, if it always worked, but sometimes perfectly correct
 email addresses don't work either.
 
 Is there any way to disable this spam-prevention so that I can send
 emails no matter what the .FROM email address is?
 
 Cheers.

 - Visual Basic >> VB5 QuestionHello,
 I have programmed in several languages, but never VB before (not regular VB
 anyway). I've got a customer with an old application written in VB5. They
 only want a few simple changes, so I picked up a copy of VB5, and am
 attempting to load the program and make some simple changes. When I try to
 compile the project, it runs across a line of code that says, "Dim rs As
 Recordset". I know what this is, but I get the error, "Compile error: Can't
 find project or library" When I click the OK button, a form comes up
 listing available references, and apparently wants me to check off one of
 the libraries that may contain a reference to the Recordset object. I
 checked off a few that seemed like the right ones, like Microsoft ActiveX
 Data Objects 2.8 Library, and a few others, but this error persists. What
 do I to resolve this?
 
 Thanks,
 Jesse

 This is my first post so I hope I'm doing this correctly. I am

 main form, there is a text box that displays the sum of total orders

 box on the main form, [GIFTS] that looks at the subtotal text box and
 depending on the value, displays one out of three options.

 in the Subtotal text box. I have entered the following code in the

 - MFC >> Build problemI've got a multi-project solution (VS 2002) which builds a bunch of DLLs and
 then an MFC application.
 
 Now, I want to get it to build the help file (.chm) ... but the interesting
 bit is that most of the topic files (and bits of the table of contents and
 so on) is actually autogenerated ... by the MFC application, when run with
 some magic command line switch.
 
 So what I need to do to build the system is:
 
 (1) build the DLLs
 (2) build the application
 (3) run the application, giving it a magic command line switch, to generate
 some help files
 (4) build the .chm
 
 Various approaches seem possible:
 
 (a) Try to do it all inside the project that builds the application,
 probably using some combination of a Project Custom Build Step and the
 Post-Build Event to do (3) and (4) (and all the other stuff that the
 Post-Build event is already doing).
 
 (b) Leave the existing project just building the application, and add a new
 project to the solution to do (3) and (4). But, what sort of project should
 it be? - there's no generic "empty project" option to which I could add the
 necessary custom build steps.
 
 (c) As (b) but use a "makefile project" and code all the dependencies for
 (3) and (4) in the makefile and maintain it by hand.
 
 Pros and cons??
 
 One issue is that it would be nice if (3) could run whenever any of the
 source files in one subdirectory of the application's project changed (as
 the application might then generate different help files), and to run (4) if
 *either* (3) was run *or* any of the hand-written help files have changed
 (which again really wants me to be able to specify a wild-card for the
 dependencies, as I don't want to have to list every single hand-written
 topic file under "Additional Dependencies"). Step (3) takes a couple of
 minutes, and (4) many seconds, so I'd like to both avoid running them when
 not necessary and make sure I do run them when they need to be run.

 - Visual Basic [VB] >> Listview select from Textbox stringI have a text box select items in a listview as text is being typed
 into the text box. I get the select bar to move correctly in the
 Listview control.
 
 If the user presses the down or up key in the text box, I want to move
 to the selected item in the listview box.
 
 The down or up arrow does set focus to the listview box and the
 selected item switches from the grey of being unfocused to the blue of
 focus. So far, so good.
 
 Pressing the down arrow again moves to the second entry in the
 listview instead of the entry below the currently highlighted entry.
 Susbsequent cursor movements work.
 
 Obviously, the selected table index that I'm using is not working
 correctly. What do I need to do to fix it?
