Trial Period


how would you do a trial period of a program? Like could you make it so that it gets the date the program is installed or first runs and count down the number of days? then make it so that the user cant use the program with out registering?

Trial Period With Password
I need a code for Excel made in VB6. It would be for sheet1 only. I want to put a time trial on it. I would like to make this work with dates not number of times used. I would also like to incorporate a kill code. I have found a few post on trial periods. When I try these codes I am never given a place to enter a password. It just kills the sheet or hides it. I would like that on a certain day that I specify a popup would appear saying "trial period over please enter password to continue". There would be a spot to enter the password, and if entered correctly would unlock it for a specified amount of time like before then ask for the password again in the future. Thank you for any help you can offer.

Trial Period On Status Bar
Hey, im using this code for a free trial


VB Code:
Dim firstRun As StringDim diffNum As IntegerDim s As String firstRun = GetSetting("AppName", "Options", "FirstRun", "0") If firstRun = "0" Then    MsgBox "Thank you for installing my product.  You have 15 days to use this."    SaveSetting "AppName", "Options", "StartDate", Date()    SaveSetting "AppName", "Options", "FirstRun", "1"Else    s = GetSetting("AppName", "Options", "StartDate", "01/01/01")        diffNum = DateDiff("d", s, Date())     If diffNum > 14 Then           MsgBox "This program has been installed for " & diffNum & " days.  You must register.", vbInformation, "AppName"           Exit Sub    Else            MsgBox "You have " & 15 - diffNum & " days left before the program is disabled."    End IfEnd If


I want to use a status bar to display the period of the trial. So when 15 days are remaining the status bar is full but when the trial has ended the status bar is empty...

Function For 30-day Trial Period Not Working Correctly. [SOLVED]
VB Code:
Private Sub CheckTrialTime()    Dim StartDate As Date    Dim EndDate As Date    Dim DaysLeft As Integer    On Error GoTo SetTrialProperties    DaysLeft = Format$(days360(StartDate, EndDate), "##") & " day(s)"    MsgBox "You have " & DaysLeft & " days left in your trial.", vbInformation, "Trial version"    Exit SubSetTrialProperties:    Set Win32Script = CreateObject("WScript.Shell")    StartDate = Now    EndDate = Now + 30    Win32Script.RegWrite "HKEY_LOCAL_MACHINESOFTWARESparkFTPMain SettingsTrial Begin Date", StartDate    Win32Script.RegWrite "HKEY_LOCAL_MACHINESOFTWARESparkFTPMain SettingsTrial End Date", EndDate    Set Win32Script = Nothing    Resume NextEnd Sub Private Function days360(dt1 As Date, dt2 As Date) As Long    Dim z1 As Long, z2 As Long    Dim d1 As Long, d2 As Long    Dim m1 As Long, m2 As Long    Dim y1 As Long, y2 As Long    d1 = Day(dt1)    m1 = Month(dt1)    y1 = Year(dt1)    d2 = Day(dt2)    m2 = Month(dt2)    y2 = Year(dt2)    If d1 = 31 Then        z1 = 30    Else        z1 = d1    End If    If d2 = 31 And d1 >= 30 Then        z2 = 30    Else        z2 = d2    End If    days360 = (y2 - y1) * 360 + (m2 - m1) * 30 + (z2 - z1)End Function


This outputs the correct starting and ending dates, but outputs "You have 0 days left in your trial." inside the message box. What's wrong?

Creating A Demo Copy Of A System W/ A Trial Period
Good day! I have created a system which will require it to be used for a limited no. of days only (say one month) after installation. After that period, the system will cease to run. Even if the user deletes the installed file(s), the system must detect that it has been installed in the same PC before and so must not be able to run even after reinstallation. Does anyone here have an idea on how to implement this? I have an idea but I'm not sure on how to implement it. Will a database or an external file be needed to store the installation date?

I would also like to ask something else. Suppose I have a .vbp file consisting of several .frm and .frx files. Will my files be affected if I rename my .vbp file? For instance, I want to save My_VB_Project.vbp as MyProj.vbp.

Thanks in advance!

Creating Conditional If Trial N = X And Trial N-1 = X
Hi everyone,
I'm using visual basic 3 to do some data analysis. I already am using a VBAB program which takes my data and creates a variable called "trial" which represents which trial it is in 450 trials and a variable for reaction time on each trial and a variable for type of code (code x, for example, specified depending on RT characteristics in my current program).
What i need to do know is get RT data from instances when I have trial N = code X and trial N-1 = code X (i.e. the previous trial and current trial are both trial type X), then output new variable "code Y". I looked through VBAB help and could not find information on marking data if i conditionalize based on current and previous characteristics on a given two trials.
Any suggestions?

Thanks a bunch!

CDO Period Stripping
I have problems with CDO

I does not matter if I use CDONTS or CDOSYS

CDOSYS
-----------------------------------------
Dim iMsg
Dim iConf
Dim Flds

set iMsg = CreateObject("CDO.Message")
set iConf = CreateObject("CDO.Configuration")

Set Flds = iConf.Fields
Flds("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "localhost"
Flds("http://schemas.microsoft.com/cdo/configuration/sendusing") = 1
Flds("http://schemas.microsoft.com/cdo/configuration/smtpserverpickupdirectory")="c:Inetpubmailrootpickup"
Flds.Update

With iMsg
Set .Configuration = iConf
.To = "someuser@somesite.com"
.From = "someuser@somesite.com"
.Subject = "Sample HTML message..."
.TextBody = "<A HREF=""HTTP://999.999.99.99/onetest.asp?File=someordinarasimple_normal.pdf&dfgdgdsf=dfgsfdgdsgfdggdsfgs""> fdshkf sdjkf hdskjfhjkdshf ksjdhf kfksd klgkdfgfjd gjfkldj gljfldjg lfdjglfjdglkd fgjdsf gljdgjfd</A>"
.HTMLBody = "<A HREF=""HTTP://999.999.99.99/onetest.asp?File=someordinarasimple_normal.pdf&dfgdgdsf=dfgsfdgdsgfdggdsfgs""> fdshkf sdjkf hdskjfhjkdshf ksjdhf kfksd klgkdfgfjd gjfkldj gljfldjg lfdjglfjdglkd fgjdsf gljdgjfd</A>"
.Send
End With



CDONTS
----------------------------------
Dim myMail
Set myMail = CreateObject("CDONTS.NewMail")

myMail.From = "someuser@somesite.com"
myMail.To = "someuser@somesite.com"
myMail.Subject = "TEST MAIL"
myMail.Body = "<A HREF=""HTTP://999.999.99.99/onetest.asp?File=someordinarasimple_normal.pdf&dfgdgdsf=dfgsfdgdsgfdggdsfgs""> fdshkf sdjkf hdskjfhjkdshf ksjdhf kfksd klgkdfgfjd gjfkldj gljfldjg lfdjglfjdglkd fgjdsf gljdgjfd</A>"
myMail.BodyFormat = 0
myMail.MailFormat = 0
myMail.Send

Set myMail = Nothing


In either case the period in the File parameter is stripped by CDO so the link will be:

HTTP://999.999.99.99/onetest.asp?File=someordinarasimple_normalpdf&dfgdgdsf=dfgsfdgdsgfdggdsfgs

How Can I Suspend A Function During A Certain Period?
Hello to all,

Within the framework of my training course of end of studies, I am brought to make an interface in vb net communicating with a db access (ado.net).

Safety devices (alarms sets fire to, etc...) are going to set informations in a db access and Iím charged of making an application allowing at any moment to visualize the state of these various devices and in the long term, to be able to modify their states.

At the time I have a value different from 0 for a sensor I must emit an aural signal, another signal with a different tonality if the value is higher than 2 and one third if value is higher than 3.

This signal resounds as much as the state of the entries of the sensor is not 0. The aural signal must be able to be cut for a period of 30sec and I do not see how to do that.

For the moment I use timers. The sweeping of the various decentralized units is carried out all the 100ms. I thus have the call of my function sweeping which is at the level of the actions carried out by the timer1.

During this sweeping, I must be able to emit an aural signal. The call of my function, SelectSound, making it possible to select the sound is located in my function of sweeping. My SelectSound function goes according to the value recovered on my decentralized unit, to start a timer (timer2, for a value=1, timer 3 value=2....) which contains the call of my PlaySound function. Until there all functions.

Now I must be able to suspend the execution of these timer for a certain period but I must continue to sweep the d.u.. And it is there that my problem is.

How can I do that? Is the use of the threads justified in my case? I tried to place my SelectSound function in a thread and to start my thread in my function of sweeping, but my sound is not played any more. The program however returns well in my SelectSound function.

Thank you in advance for your assistance

Rolling 6 Month Period
I have a table that records login and logout entries for the reps that work in our phone department. When a rep misses a day, it is considered an negative performance occurrence. Each rep is given a warning when he/she reaches 4 occurrences within a 6 month rolling period. For example, the rep is late on 1/1/2005, 2/3/2005, and 3/2/2005. If the rep misses a day after 7/1/2005, the rep will still only have 3 occurrences within the 6 month rolling period (2/3/2005, 3/2/2005, and the newest entry). I'm trying to design a query that captures this dynamic environment, but I can't seem to find a good start. I've tried searching for the count of entries using a subquery. The main query searches for a date that meets the absence criteria (displayed field), then returns a count of entries that contain the absence criteria between the date of the first entry and a date 6 months in the future. Any ideas?

Best Way To Pop A Reminder Over Long Period?
Hello,

Access database holds a date which the user has input using the Monthview Control, another field calculates the next date the user needs
to visit for an oil change, engine repair etc. anywhere from 3 months to 2yrs which is in date from MM/DD/YYYY.

I want to put that next date into a pop up reminder, and give the user an option to pick another Date/time.

Been looking at the timer control, seems crazy to have that thing ticking away for years, is there a better way?

Also how would I tie the reminder date MM/DD/YYYY to trigger the timer control, and have multiple reminders?

Is there any third party timer controls that you recommend? or a better way?

KeyAscii Code For A Period
I have this in the keypress event of a control to prevent anything but numbers from being entered. However, I do need to allow decimal numbers, so what would I add as the keyascii for a period as being an allowable characters?

Allow Numeric, Comma (,) And Period (.) Only
Hello, I want to just allow the user to type numberic value and a period just like typing money figure like $1.25.

VB Code:
If KeyAscii = vbKeyBack Then 'backspace    Exit Sub  ElseIf KeyAscii = 13 Then 'or vbkeyreturn    txtPurchasePrice.SetFocus  ElseIf KeyAscii < 48 Or KeyAscii > 57 Then  'Allow Numeric only    KeyAscii = 0  End If

VB6 - TextBox - Period/comma
Hi

I have a small accounting programa.(I am studing on it)
I have a TextBox to enter the numbers.When I use a comma (,) before of the
cents everything works well, but if I use the period (.) before the cents I
get a wrong number.

Ex. If I enter 10,10 ( with comma) I get 10,10 what is ok.

Another Ex: If I enter 10.10 (with period) I get 1010,00 what is wrong.

Any help to solve this problem.

My Code is :

Private Sub Text1_KeyPress(KeyAscii As Integer)

If KeyAscii = 13 Then
SendKeys "{tab}"

If Text1.Text = "" Then
Text1.Text = 0
End If

If Text1.Text = "" Then Exit Sub

If Not IsNumeric(Text1.Text) Then Text1.Text = 0

Text1Text = Format$(Text1.Text _
, "###,###.00")

End If

End Sub

Lock Vb App After Inactivity Period
Has anyone some code / references how to find out how long a program has been inactive (no clicks / form focus)?

I'm using vb6 and mdi forms.

Most answers seem to say just a timer with a reset for every text box and click etc. However, this is a lot of code to put in and won't work for MDI forms with no mouse events.

I.e. If my program receives no activity for 15 minutes because the user walked away or is using another app on the system (so different to the screensaver starting), I want to display a log in form.

PLEASE HELP!!!!!!

Thank you,

Alan

Calculating Price From A Period Of Time
Hi, I am currently exploring vb..and somehow stuck on this question posted to me by my friend.

Lets say I want my program to calulate exchange rates base on certain period of a year. Example:

At the month of March and Decemeber the exchange rates will be at 130% while for the remaining month it will be of the normal range.

So how am I going to get the data from the txt file using random access and read the data and then using the same "normal range" and predetermine the exchange rates base on my txt file "normal range" price and the date.

Can someone help me? I am so stuck at it. Thanks..

Converting ESC To Period In Generic Printer
I have an application that requires printing labels to a Label Printer. The control of this printer requires the use of the ESC char. The problem that I am experiencing is that when command is sent to this printer with an ESC embeded in the command, it is replaced with a period. And the printer does not know what to do with it. So, to re-state this problem, How can I send and ESC char thru the Windows Printer object? Any and all Help is deeply appricated.

How To Calculate The Period Of Time For A Loop
I have a simple running loop in my code, which is shown below

Do While ((recieved_data <> "ACK") And Not (time = 300000))
recieved_data = MSComm1.Input
time = time + 1
Loop

Is there any way of calculating how long this count will take, maybe using the speed of the computer to calculate the time the loop goes for. Using a stopwatch, this loop takes on average 3.55 seconds.

And before you mention a timer, they don't work when your using a do while loop. They just can't seam to be accessed.

Jumping Out Of A Do While Loop After A Period Of Time
Below is a simple piece of code and it works fine. We send a command to the robot to turn right. When the robot turns, it sends back an acknowledgement. I dont want the program to send anymore commands till the robot is ready. So I wait in my do while loop for the ACK. However sometimes the ACK is lost and therefore I am trapped in my do while loop forever. Is there some way I can set a timer inside the do while so that after a period of time, I can jump out of the loop. Could we use a timer and once thats finished then use the do events command to pass control back to the user??
any ideas would be grateful.


Private Sub pulse_right()
MSComm1.Output = "h"

recieved_txt.Text = recieved_data

Retrieve Number Of Equipments In A Certain Period
Hi guys,
I have the following:
A table filled with reparations records from a maintenance department. The rows contain ofcourse all different kind of info, for example, customer name, the date the equipment came into the maintenance department, the date the equipment returns to the customer, product classe etc.
I want to know the following:
- The number of equipments that came into the department in a certain period;
- The number of equipments that went back to the customer in a certain period;
- The difference between these to numbers (in order to measure the difference in stock);
- Group by product class.

I figure that the result will look something like this:
Product class | Number IN | Number OUT | Difference
A | 3 | 3 | 0
B | 8 | 5 | 3
C | 4 | 2 | -2

Any suggestions??

Thank you in advance

Winsck Disconnects After A Period Of Time?
(Before I get to far...........YES...I have already asked this question once before but the probl1em was a little different, I needed help trapping the winsck errors.)

I have written a chat program that is having a little trouble. For some reason the client and server will get disconnected after a period of time. At least I think they get disconnected but the msgbox in the connection close sub doesn't popup? When the two have set idle for an extended period of time and the client tries to send data to the server the server pops up the following error:
"Subscript out of range"

Is there some sort of time out settings on the winsck control or should the connection remain until one end disconnects? Is there something I can do to maintain a persistant connection between the two?

Thanks!

Set Time Period To Execute A Command In VB

Time Interval Within The Date Period
Hello,
I've spent few days seaching and finding out how to do this in vba but with no satisfying result.

F. ex.:
Date period: 25-09-2007 13:00 to 26-09-2007 23:00

time intervals: 06:00-15:00, 15:00-18:00, 18:00-03:00 and 03:00-06:00

I need to know total of hours for each time interval within the date period.

The result should be this:

06:00-15:00 = 11 h
15:00-18:00 = 6 h
18:00-03:00 = 14 h
03:00-06:00 = 3 h

Just to say that date period as well as start- and end times can vary in length.


I would very appreciate every help
