General Software Discussion / Visual Basic 6 App.s in need of way to charge for usage, ideas?

« on: November 03, 2023, 11:28 AM »

5 App.s have a Windows front-end written in Visual Basic (6) that submits a DOSbox program for executing. I would like to charge for usage after 'x' days of usage similar to streaming TV channels due; i.e., no usage then no charges until usage begins again.

Each DOS app may be started with the front-end OR a batch file that by-passes the front-end. After 'x' days, these runs must verify that it is a 'paying' customer.

Anyone interested in solving this problem?

General Software Discussion / Seeking Web Partner to handle Google Merchant Center & other marketing/sales

« on: September 16, 2023, 10:56 AM »

I'm seeking a web partner that is capable of handling Google's Merchant Center and other marketing/sales stuff in exchange for a percent of my website revenue. My site has been in development for 30 years and has 400 visitors per day. Google suggests it will bring in $5,000 / month!

My website, goal-driven.net, tries to show Engineers and Scientists how to solve many math problems from industry. The key is a (free) Calculus (Level) Compiler that solves most math problems in Industries.

My compiler got its start at NASA's Apollo Space program back in the early 1960s. Known as Slang back then, it got the USA to the moon and back. When introduced to Industries in 1974, it then was called PROSE. Today it is FortranCalculus.

Hope you like the proposal idea

General Software Discussion / Method of Lines (MOL) for solving Partial Differential Equation(s) (PDEs); needs

« on: September 11, 2023, 11:35 AM »

My website, goal-driven.net, shows how to solve most (continuous) math problems, but needs some MOL examples showing equation necessary to solve a given PDE; e.g. Schrodinger, Maxwell, telegraph, wave, etc. You provide
1. MOL & PDE equations;
2 a description of where you/they are used in industry(s); and,
3. Your Title & Name & email address (?), e.g. President: Tom Jones, [email protected]
#2 & 3 will be placed as 'Ads' on my website to bring you some business

Think marketing/sales when stating a description. Here is an example PDE. I'm seeking 5 examples, the best 5 win!

In return, I'll publish #2 & 3 on my website AND provide you with a copy of my (free) Calculus (Level) Compiler that can solve PDEs using MOL.

Living Room / Google Merchant Disapproved Invalid (1 country), How do I fix this?

« on: August 31, 2023, 11:50 AM »

I have 5 software Apps, they are all 'free software' that are for an Educational purpose And some also for Business as well. My feed shows Target Countries as having ALL countries. Is this the problem as some posts have said so. If so, how to remove those which should NOT be included? How many need removing?

At present, my biggest users (ie. downloaders) is China ... 30X that of next largest (USA)! Each App has between 50-100 downloads / day.

Any ideas?

Announce Your Software/Service/Product / Matched Filter (Transfer Function; Poles-Zeroes) Computer Aided Design (CAD) App

« on: July 18, 2023, 10:24 AM »

Match-n-freq™ is a (free) Pulse Shaping Filter program that finds the pole-zero locations of a transfer function, H(s), for a matched-filter design. H(s) equals a -desired- signal (Yout) divided by a given input signal (Yin). Both Yout and Yin are functions of frequency. Download at https://goal-driven....ps/match-n-freq.html .

H(s) has an option to equalize its sidelobe peak amplitudes in a Bode plot; i.e., Peak i = Peak j for all i, j.

Group delay, Td, is calculated to compliment a given dataset, thus, providing a maximally flat group delay. A search for Group Delay definition on the internet shows various results and thus leaving the question which are true? A textbook from 1980 differs from what is seen on the internet. They may be equivalent but not sure. So the basic equation is Td = Partial( H(s)) with respect to 's' / s, where s = 0 + j w. Be careful when using some other App or even my App as they try to calculate Group delay. If the professors don't agree, how can us developers get it 'right'? I have worked on this problem on & off since 1979 and finally think it is done! If you find an error, PLEASE let me know

Match-n-freq™ finds an Optimal solution for a H(s) match and maximally flat group delay; a one time process! One must determine what Poles &/or Zeros are necessary for their datasets and this may require several runs. But with the speed of today's PCs, a half-day should have your problem solved.
---

This Matched Filter CAD App is an example of what other redundant problems can be solved using this as an example. The source code is included in the download; search for *.fc & *.inc files plus Visual Basic code files for the front-end.
---

The reason this and other Apps were developed by me was to demonstrate the simplicity & power of a Calculus-Level language/compiler; e.g., FortranCalculus visit https://goal-driven....pps/fc-compiler.html for more; freeware too. I taught FortranCalculus from 1975 to 1979 in the SF Silicon Valley to Engineering & Science companies. Also taught MACSYMA at Lockheed Missiles & Space Co. for 2 years... a lost cause, FortranCalculus wins hands down.

Post New Requests Here / Need buttons to download a file and disable used button, how to do so in HTML?

« on: July 06, 2023, 01:19 PM »

I have several download buttons that are to be clicked only once, in a table. Each button has an ID = "btnXXX", how does one get this to work?

Each button, set of two, has code as follows:

[Select]

<tr class="topic">
<td>Descript 1</td>
<td><a href="abc.ppt" download></a>
<button Id="btn1-1" class="button btn1"
onClick=“download_file()”>PPT</button></td>
<td><a href="abc.pdf" download></a>
<button Id="btn2-1" class="button btn2"
onClick=“download_file()”>PDF</button></td>
</tr>

This <tr> is duplicated some 10 to 20 times with different "Descript #", download file names, and button IDs. Need a function "download_file" that downloads a file and disables used button. There are two button IDs; btn1-# and btn2-#. Each of these buttons may individually be clicked on in each <tr> set. So e.g., 15 <tr> groups then 30 buttons for user to check from.

General Software Discussion / Visual Basic 6 App.s in need of a registry addition.

« on: May 11, 2023, 06:30 PM »

My code comes from another of my App's ... some code not working in my new app.s is as follows:

ooo

' Set 'tPause' value in Registry
If CheckRegistryKey(HKEY_CURRENT_USER, RegODEkey) = False Then
CreateRegistryKey HKEY_CURRENT_USER, RegODEkey

SetRegistryValue RegODEkey, "tPause", tPause.Text
End If
tPause.Text = GetRegistryValue(RegODEkey, "tPause", REG_SZ)
If tPause.Text = "" Then tPause = "20"
ooo

' Write / Create a Registry value.
' Use KeyName = "" for the default value.
' Supports only DWORD, SZ, and BINARY value types.
Sub SetRegistryValue(ByVal hKey As Long, ByVal KeyName As String, ByVal ValueName As String, ByVal KeyType As Integer, value As Variant)
Dim handle As Long, lngValue As Long
Dim strValue As String
Dim binValue() As Byte, length As Long

' Open the key, exit if not found.
If mdlRegistryAPI.RegOpenKeyEx(hKey, KeyName, 0, KEY_WRITE, handle) Then Exit Sub
Select Case KeyType
Case REG_DWORD
lngValue = value
RegSetValueEx handle, ValueName, 0, KeyType, lngValue, 4
Case REG_SZ
strValue = value
RegSetValueEx handle, ValueName, 0, KeyType, ByVal strValue, Len(strValue)
Case REG_BINARY
binValue = value
length = UBound(binValue) - LBound(binValue) + 1
RegSetValueEx handle, ValueName, 0, KeyType, binValue(LBound(binValue)), length
End Select

' Close the key.
RegCloseKey handle
End Sub

Ideas where my problem is? My app can be downloaded at goal-driven.net/download/ and choose "Match-n-Freq (v. 6.6) ... 4 mB" ... its free and has VB6 source code with it.

General Software Discussion / How to close a Fortran DLL routine when exiting Visual Basic (front-end) program

« on: July 17, 2018, 11:27 AM »

Hi,

I'm having problems with my VB6 program that merges with a Lahey Fortran DLL. It has been around for over 20 years! The DLL was started around 5 or 10 years ago. My VB6 program may call the DLL 1 or more times with no problems. Then on closing, the program hangs!!! If one doesn't call the DLL, no hanging occurs on closing. Ideas?

1. Phil Brubaker
2. S/N: 001873...
3. Lahey/Fujitsu Fortran 95 Express Release 7.10.02
4. Patch level?
5. OS: Windows 7
6. Example VB6 code:
Private Declare Sub PSDcalc_for Lib "PSDcalc_for.dll" (ByVal fileNam As String, ByRef x_array As Single, _
ByRef spectrum As Single, nptsZ As Integer, npointsZ As Integer, _
t_startZ As Single, t_finalZ As Single, zeroFillZ As Single, sig2Z As Single, _
nPoles As Integer, nZeros As Integer, M_eqs As Integer, M_lags As Integer, _
Mode As Integer, L_pts As Integer, ByVal str_len As Long)

ooo

ReDim x_array(1 To npointsZ) As Single, spectrum(1 To npointsZ) As Single
x_array(1) = 1: spectrum(1) = 1
ChDrive App.path: ChDir App.path

Call PSDcalc_for(fileTemp, x_array(1), spectrum(1), nptsZ, npointsZ, _
t_startZ, t_finalZ, zeroFillZ, sig2Z, _
nPoles, nZeros, M_eqs, M_lags, Mode, L_pts, _
Len(fileTemp))

If nptsZ < 1 Then
MsgBox "File Error ... read bottom of your '~rainbow.out' file for " & vbCrLf _
& "more details. This OUT file is in the same directory " & vbCrLf _
& "as your input file; ... " & vbCrLf _
& " " & fileTemp, vbOKOnly, "File name in error ... " _
& "read Output file for more"
Call createFileOut(fileIn)
Exit Sub
End If
Call createFileOut(fileIn)
ooo
-------------------------------------------------------------------------------------

F90 code:
------------
Subroutine PSDcalc_for( fileNam, x_array, spectrum, nptsZ, &
npointsZ, t_startZ, t_finalZ, zeroFillZ, sig2Z, &
npolesZ, nzerosZ, M_eqsZ, M_lagsZ, modeZ, L_ptsZ)

dll_export :: PSDcalc_for
character(len=*) :: fileNam

include 'spec_in.inc'

complex signal_amp( :)
real y_array( :), norm_factor
real, dimension( npointsZ) :: x_array, spectrum
allocatable :: y_array, signal_amp
--------------------------------------------------------------------------------------

This code works, can call PSDcalc_for several times ... AOK. Then try closing my VB6 front-end and vb6 seems to hang. Create an EXE for my project and it too runs fine until closing. Then it tries closing and gets the same error msg.

This app has been running since 1994 (?) with no problem, what is new that causes such error? I found a back-up with same DLL, back in 2015, and it too aborted with same error! The app is not used that often by me, so unclear when this shutdown error msg. started.

Any ideas on how to close down my Fortran DLL, without forcing it just a 'normal' close?

Thanks, Phil

Announce Your Software/Service/Product / FortranCalculus (FC) Computer Language

« on: June 21, 2018, 10:35 AM »

FortranCalculus (FC) language was developed in late 1980s to replace PROSE language that ran on Time-Sharing computers starting in 1974 on a CDC 6600 computer. PROSE and now FortranCalculus help Engineers & Scientists solve their math problems, in minutes!

FC Compiler improves Math Modeling, Simulation & Optimization efforts by improving their productivity by 20 times! Solutions are Faster, Improved Accuracy, & Cheaper.

The FC compiler simplifies solving math problems by minimizing code necessary to state & solve a problem. Some new thinking is necessary for those wanting to get the most for their buck; convert from simulation to optimization thinking.

If you were a manager or CEO and had the choice of a simulation design versus an optimization design, which would you pick?

Teach Educators: Modeling & Simulation’s next step is (Mathematical) Optimizations. Optimizations require a design Goal or Objective (function). Today's Engineers & Scientists solve problems with a “Find X” mind-set. With some Operational Research training they could expand their thinking to a “Find X to Optimize Y” mind-set. Then they would be ready for Optimizations, Calculus-level programming and software. (This would drop today’s design times that require months even man years to one or two days! Manufacturing processes could be optimized to the days demand and thus maximize their profits.)

“Find X to Optimize Y” thinking among professors will cause most engineering & science textbooks to be rewritten with optimization examples and discussions. This will be great stuff for industries and government; applied engineering and/or science not just theories.

A little history, in 1974 Calculus programming was introduced at a Society of Industrial & Applied Mathematicians (SIAM) conference. Two professors heading the conference would -not- allow this paper to be printed since they realized what it would do to their (numerical methods) field of work. (Few, if any, professors are aware of what can be achieved thru Calculus Programming.) Help, we need Engineering & Science professors to teach the “Find X to Optimize Y” mind-set.

Design Goal | Objective required for Optimization
• Engineers & Scientists need to move from a “Find X” mind-set to a “Find X to Optimize Y” mind-set teaching in schools.
• Industry/Company Leaders need to state their company objectives so ALL employees know it; Leadership by objectives.
