Re: What directory is my application located in?
You can always check Application.ExeName to get the path and filename of the currently running executable. If you only want the Path portion, pass it to ExtractFilePath and if you only want the filename, pass it to ExtractFileName., , Hope this helps,, Larry

Re: Tray Icon
My recommendation is to go to [URL=http://www.torry.net]http://www.torry.net[/URL] and do a search for TCoolTrayIcon. This component is free, with source, and is the best tray icon component available. It works with Delphi 2 - 6 and C++ Builder 3 - 5. It has features for hiding and showing the main form, for making the main form minimize and close to the tray, it has design time preview of the tray icon, popup hints, menus, tray icon animation and a couple demo apps to help you get started using the many features available., , Hope this helps,, Larry

Re: Registry
To use TRegistry, you have to identify the root key, then open the sub-key you want to work with and finally read or set any values stored in that key. Here's an example:, , , [b]procedure[/b] TForm1.Button1Click(Sender: TObject);, [b]begin[/b], [b]with[/b] TRegistry.Create [b]do[/b], RootKey := HKEY_LOCAL_MACHINE;, OpenKey('\Software\Microsoft\Windows\CurrentVersion\Run', False);, // The second parameter in OpenKey, if True, will , // create the key if it doesn't exist, WriteString('MyApp', Application.ExeName);, CloseKey;, [b]end[/b]; , [b]end[/b];, , , Hope this helps,, Larry

Re: procedures
The reason it won't compile is because the procedure [b]nextQuestion[/b] is referencing objects owned by the form, but it is not aware of the form. There are two ways to resolve this issue:, , 1) Reference the form within the procedure:, , , [b]procedure[/b] nextQuestion;, [b]begin[/b], Form1.lblQuestion.Caption := Form1.Memo1.Lines[Count];, [b]end[/b];, , , 2) Make the procedure a member of the form:, , , [b]interface[/b], , [b]type[/b], TForm1 = [b]class[/b](TForm), ..., [b]public[/b], [b]procedure[/b]nextQuestion;, ..., [b]end[/b];, , [b]implementation[/b], , [b]procedure[/b] TForm1.nextQuestion;, [b]begin[/b], [i] // Note: The procedure is now a member , // of the form, so there is no need to, // reference Form1[/i], lblQuestion.Caption := Memo1.Lines[count];, [b]end[/b];, , , Hope this helps,, Larry

Referencing a control by name.
I'm a bit of a newbie to Delphi, sorry if this is a dumb question., , I have a string variable that will contain the name of a table object and another that will contain the name of a field within that table., , I'd like to know how to reference the table by name (like it is possible to do with FieldByName) - is that possible?

Re: Delphi Enterprise vs. Professional
Unfortunately, the Enterprise edition includes more specific database drivers, which are not available in the Professional edition. The only suggestion I can think of would be to create an ODBC connection to the database, and then modify the source to use the ODBC connection, instead of the native connection., , Hope this helps,, Larry

Re: Reading From A Barcode Scanner
The first thing to try, is to get in touch with the scanner's manufacturer and see if the software is still available. If that option doesn't work, then you will need to obtain or build a COM port sniffer to watch the data coming in from the device. Then you can begin deciphering the data coming in compared to what you scanned. Once you understand the data, you can build an app to read the data from the scanner., , Hope this helps,, Larry

Re: CR/LF problem
It depends on how you are writing to the file. If you use [i]WriteLn[/i] then it will always append [CR][LF] to the end of each line. However, if you use [i]Write[/i], then nothing is appended and you can write out a [LF] wherever you want it to appear., , For example:, , [b]procedure[/b] Form1.WriteToFile;, [b]var[/b], OutFile: TEXTFILE;, , [b]begin[/b], AssignFile(OutFile, 'temp.txt');, Rewrite(OutFile);, Write(OutFile, 'This is the first line.' + #10);, Write(OutFile, 'This is the second line.' + #10);, Write(OutFile, 'And this is the final line.' + #10);, CloseFile(OutFile);, [b]end[/b]., , , Hope this helps,, Larry
