This manual applies to the MarshallSoft DUN Dialer (MDD) for all supported languages.
We have versions of MDD for C/C++ (MDD4C), Delphi (MDD4D), Visual Basic (MDD4VB), PowerBASIC (MDD4PB), Visual FoxPro (MDD4FP), Visual dBase (MDD4DB), Alaska Xbase++ (MDD4XB), COBOL (MDD4CB), and Fortran (MDD4F). All versions of MDD use the same DLL (MDD32.DLL).
The complete set of documentation consists of three manuals in three formats. This is
the second manual
(MDD_USR) in the set.
Each manual comes in three formats:
The MDD4x Programmer’s Manual is the language specific manual. All language dependent programming issues are discussed in this manual. Read this manual first.
The MDD User’s Manual (MDD_USR) discusses email processing as well as language independent programming issues. Read this manual after reading the MDD4x Programmer’s Manual..
The MDD Reference Manual (MDD_REF) contains details on each individual MDD function.
Use Microsoft Word 97/99 or Microsoft WordPad to print the document files.
We want you to be successful in developing your applications using MDD! We are committed to providing the best library that we can. If you have any suggestions or comments, please let us know.
If you are having a problem using MDD, refer to Section 8.0 "Problems". If you still cannot resolve your problem, email us at
support@marshallsoft.com
You can also reach us at 256-881-4630 between 7:00 AM and 7:00 PM CST Monday through Friday. You can also often reach us on Saturday.

The MarshallSoft Computing newsletter "Comm Talk" is published quarterly on our web site. It discusses various communications problems and solutions using our products as well as related information.
MarshallSoft Computing, Inc. is a member of the Association of Shareware Professionals (ASP). ASP wants to make sure that the shareware principle works for you. If you are unable to resolve a shareware- related problem with an ASP member by contacting the member directly, ASP may be able to help. The ASP Ombudsman can help you resolve a dispute or problem with an ASP member, but does not provide technical support for members' products. Please write to the ASP Ombudsman at 157-F Love Ave., Greenwood, IN 26142 USA, FAX 317-888-2195, or send email to omb@asp-shareware.org.
The professional version of MDD may be registered for $40 (US dollars) for email delivery. The professional version DLL is also branded with your company name.

The MarshallSoft DUN Dialer (MDD32.DLL) is implemented as a Win32 dynamic link library (DLL). A DLL is characterized by the fact that it need not be loaded until required by an application program and that only one copy of the DLL is necessary regardless of the number of application programs that use it. Contrast this to a static library which is bound at link time to each and every application that uses it.
MDD functions can be called from WIN32 console mode programs as well as GUI programs. A "console mode" program is a Windows 95/98/2000/NT WIN32 command line program running in a command window. Although console mode programs look like DOS programs, they are WIN32 programs which have access to the entire Window’s address space.
The first MDD function that should be called is mddAttach, which initializes the MDD library and allocates necessary resources. mddAttach is typically called in the initialization section of your application.
Before exiting your application, mddRelease should be called. mddRelease should not be called if mddAttach failed.
The best way to get familiar with MDD is to try out one of the example programs. The example programs are described in the MDD4x Users Manual:
MDD4C C/C++ MDD4F Fortran MDD4D Delphi MDD4CB COBOL MDD4VB Visual Basic MDD4XB Xbase++ MDD4PB PowerBASIC MDD4FP Visual FoxPro MDD4DB Visual dBase
The MarshallSoft DUN Dialer (MDD) library is available in three versions. All three versions have identical functionality.
The shareware version can be differentiated from the other two versions by:
mddDebug(MDD_GET_REGISTRATION, Buffer, BufLen)
The Shareware version may not be used for commercial purposes.
The student version can be differentiated from the other two versions by:
" STUDENT VERSION [http://www.marshallsoft.com]"
The Student version may not be used for commercial purposes.
The professional version can be differentiated from the other two versions by:
The professional version may be distributed with your application as specified by the software license. See Section 1.4 "Ordering" for details on ordering.
The MarshallSoft DUN Dialer MDD32.DLL can be used with any application written in any language capable of calling the Windows (95/98, NT,2000) Win32 API
Declaration files have been defined by the following languages:
C/C++ MDD.H Visual Basic MDD32.BAS VBA (Excel, Access,…) MDD32.BAS PowerBASIC MDD32.BAS [not the same as above] Borland Delphi MDD32.PAS Fujitsu COBOL MDD32.CBI ABSOFT FORTRAN MDD32.INC Visual FoxPro MDD32.FOX Visual dBase MDD32.CC Alaska Xbase++ MDD32.CC [not the same as above]Additional declaration files will be added. Give us a call if you need a declaration not listed above. If you have interfaced MDD to an unusual language, email us the declaration file!
5 Problems
First, be sure you are passing the proper key code. See section 2.4 "Key Codes".
Be sure to test the code returned from MDD functions.
If you still get the shareware screen after registering, the problem is that Windows is finding the shareware DLL before the registered DLL. The solution is to delete (or zip up) all shareware versions of MDD32.DLL.
If you get "error -74" when calling mddAttach, the problem is that the keycode passed to mddAttach does not match the keycode in the DLL's. This is caused by (1) using the shareware keycode (value = 0) with the registered DLL, or (2) using the registered keycode with the shareware DLL.
If you cannot get your application to run properly, first compile and run the example programs. If you call us to report a possible bug in the library, the first thing we will ask is if the example programs run correctly.
If you encounter a problem that you cannot resolve, give us a call or email us at support@marshallsoft.com.
See Section 1.4 "Ordering" for information on ordering.
MarshallSoft Computing, Inc. grants the registered user of MDD the right to use one copy of the MDD DLL's on a single computer in the development of any software product. The user may not use the library on more than one computer at the same time.
The "student" ($30) registered DLL's may not be distributed under any circumstances, nor may they be used for any commercial purpose.
The "professional" ($40) registered DLL's may be distributed (without royalty) in object form only, as part of the user's compiled application. The registered DLL's may NOT be distributed as part of any software development system (compiler or interpreter) without our express written permission. When you register, you will be sent a "key code" which enables access to the registered DLL's. You may NOT distribute or make known this key code. (see Section 2.4 "Key Code").
