Have you compared the running processin the Control panel both ways?

The compiler reads and translates the code you write. All names etc are dropped so if there is a way to read the compiled code and identify the logic, it would still not have any names or other clues to what was what.

Before worrying about putting it all together, work on the parts of the program. For instance, you have identified the record to store your data, but how are you loading user input into the record array? Solve this as you would eat an elephant, one bite at a time. In …

FlamingClaw's example is for using an editbox in a Form application. Are you creating a form or are you doing a consule application?

EXE files are compiled. The code has been removed and replaced by an instruction that operates the computer. You must get a copy of your friend's uncompiled code to review or change it.

FlamingClaw, Two thoughts on your example: 1.) i := i + 9; // does not increment by 10 2.) Using the For statement could easily lead to an error in a large body of code. Imagine coming back to this a year from with no memery of the logic. You …

It looks like only a few lines actually change. Why don't you put the graphic in a loop with the few lines that change as a separate method? You can use counters to keep track of when to begin or change the lines that require it.

There are a number of conversion functions the sysutils.pas unit that can test this for you and check out extractstrings in the Classes unit for a basic parsing function.

Another possibility would be to create a small database structure and placing the items in a database file. IF you have not explored database managment in Delphi yet, then this would be a good opportunity to do so. You may also want to reconsider the idea of user access. Many …

IS "formvar" part of Delphi or your own method? I could not find a reference for it and am not familiar with it. Either way, what is the declaration for the function? Have you looked at tstringlist? Also check out extractstrings in the Classes unit.

What is the purpose of the integers Head and tail? Are they needed? Look at how you are using them and follow the value of Flip1 using debug monitors.

Take a look at Sysutils.pas. There a number of date/time methods that manage date operations.

To save LizR the effort let me ask you: What have got thus far? Have you developed any parts of the algorithm such as how to read the file, how to store the data for use, or how to determine the distances?

I just ran across some code that declares a complex packed record: aSInt = Integer; [ICODE]entity = packed Record Enttype : byte; field2 : double; ... //continues with other standard fields and then uses this case CASE aSInt OF entlin: (linpt1, linpt2: point); entln3: (ln3pt1, ln3pt2: point); entmrk: (mrkpnt, mrkvec: …

Have you tested this? What happens? What help are you looking for?

I am working on a project for a Cad program in which I must embed data in the Cad file. The tools for doing so in the cad program allow for embedding boolean, integer, double byte and string values, one at a time. There is a lot of data and …

The unit sysUtil.pas has a number of string routines including several that can be used to search through the string to find the spaces between words and allow you to extract the words individually for each line.

I am trying to use a clientdataset without an associated Table. I am attempting to extract and edit data from a Cad program. The Cad program has an interface in which the user selects specific entities within the Cad file (lines, circles, text etc) and provides basic information and attributes …

your array is "a" with 1 through 7 as the items. You addressed it correctly in the readln (a[i]) To test element three you would use a [3] or a [i] for a variable in a loop. if (a[i] < 1) or (a[i] >7) then I suspect that your having …

I have a question for LizR here. I have read and written into Excel spreadsheets using an ADO table and Clientdataset setup. It is my thinking that this would note require Excel to work with the Excel file. The set-up for doing this takes some knowledge of ADO databases to …

I am not certain I understand what you are asking. That is to say what level of experience you have with programming in general. You mention using DB related compnenets, but it is not clear if you understand (yet) how they work There are several excellent tutorial sites: Delphi.about.com has …

Darkyere, Check out this site: [url]http://blogs.codegear.com/nickhodges/2006/08/15/26687[/url] These demonstration files are excellent tutorials for beginners on many features of Delphi including using the debugger. Since your new, it would pay to spend a day going through all of them.

A Stringlist is a class of Tstring. It contains a list of strings that can be accessed and managed through the various methods (add, delete, find etc..) It also allows you to separate each string using a NameValueSeparator. The character assigned to this property is used to separate any of …

I'm not sure of your intent. I visualize three compnents on the form, the list box with the user names, and two text boxes, one for names and one for passwords. IF you have a listbox that has read the nnames, then it is a simple matter for the user …

This question is too vague to answer. Can you be more specific about what you did three years ago and what you want to do now. Are you trying to modify code or are you trying to duplicate what is shown on the sample site?

Have you placed the code from pritaeas in your MyButtonClick method?

I have a recurring problem: On some days, it appears that Delphi has problems with identifying some of the files in my "Uses" section. Certain files will be underscored in red zig-zag and identified in the structure window as "cannot resolve unit name ...". If I right click the unit …

A couple of questions come to mind: Are you having this problem in design mode or at run time? Have you opened your dataset? Have you correctly set the current record to the one you want? I am currently writing my first Delphi Database program but am having some other …

I am writing a program that uses two modules, a VCL win32 application module and a Datamodule to contain ADO components and a clientdataset to work the data in memory. When compiling the code fails with the message Raised Exception class EAccessViolation in Module EstimateMngr.exe. The debugger shows failrue in …

I am not familiar with Absolue Database. My first thought would be to try the same thing connecting to another database (BDE or ADO) and see if you still have the eror. How are you connecting between the grid, the datasource, Table and the database? I everyting wired up correctly?

Your question is too vague. Are you asking how to connect to a database, or how to structture the data? You may want to start by identifying what needs to be tracked. Such a list will certainly help the programmer plan the work. The programmer should know the how to …
