If you have over 105+ (mine only has 11) look closely at record 105 and see if you can see anything wrong.
Tutorial: Creating A FoxPro Application Tutorial: Creating A FoxPro Application Dr. Hicks Computer Science Department Trinity University Organize Files & Create Directories/Folders Do wnload and decompress the following FoxPro Database Files into directory C: Temp RestaurantApp 1 The contents of the initial folder should be the Rest.dbf, Rest.cdx, and Rest.fpt.(See Below!) 2 In order to easily find the wizards that we are going to use on any computer, I recommend placing at least the four screen wizard file in your directory. 3 In order to keep from having dozens of files at the root level, it is best to organize the various files for an application. Some of them will have to be kept in the root directory, but others we shall organize by topic. For example, we shall place all of our images in the BitMaps directory.
We shall place all of our forms in the Forms directory. We shall place all of our Reports in the Reports directory. We shall place all of our database tables and indexes in the Data directory.
We shall place all of our program code in the Programs directory. Create all of the directories that you see below. This is a very simple database application with no relationships and only a single file. For an application as simple at this, we shall not yet use the Help, Include, Libs, Menu, or Other directories. 4 I am including several of the bitmap images that I use for applications in the file below. Extract them and add them to the BitMaps folder. (See Below!) 5 Move the three rest files into the Data folder.
(See Below!) 6 This should leave the folowing files/directories at the root level. (See Below!) Create A Database Project 1 Start FoxPro. Important Set Default to C: Temp RestaurantApp! (See Below!) 2 Using the mouse, hold down the File Menu and select New (See Below!) 2 Using the mouse, select the Project Radio button. Using the mouse, push the New File button. (See Below!) 3 If you have set the default properly, the RestaurantApp folder should be in the Save In bar at the top; Enter a project name of Rest. Using the mouse, select/push the Save button.
4 The project is now created. (See Below!) 5 This new project should have added files Rest.PJT and Rest.pjx to the root of the RestaurantApp folder. Check it out! (See Below!) Create A Database 1 Expand Data or select the data tab. Select Database.
Using the mouse, select/push the New button. (See Below!) 2 Using the mouse, select/push the New Database button. (See Below!) 3 Enter Rest in the Enter Database dialog box. Using the mouse, select/push the Save button. (See Below!) 4 We now want to add all of our database tables to the database.
Using the mouse, select/push the Add Table button.(See Below!) 5 Go to the Data folder and select each of your tables; only one in this application. (See Below!) 6 You database now has the Rest Table associated with it! (See Below!) You may also create new tables with the New Table button. Tables inside the database are permitted to have much longer field names. 7 The application provides easy point and click access to all databases, all tables, and all fields in the tables.
8 The view below shows the Rest table expanded in the Data tab view. Note that you can modify the table structure or browse the table from this view. (See Below!) 9 Note that this has added files Rest.DCT and Rest.DCX to the root of your application folder. (See Below!) Create The Rest Form 1 Select the Documents Tab. All Reports, Labels, and Forms are to be organized here. Using the mouse, select/push the New button.
(See Below!) 2 Using the mouse, select/push the New Form button. (See Below!) 3 It is not the purpose of this tutorial to teach form or report design. Check one of my other tutorials. Create the following form. Put your name at the menu bar in place of mine. Save it as Rest in the Forms folder/directory.
We shall not use all of the buttons yet! (See Below!) Special Rest Form Settings and Events.
Destroy Event application.visible =.T. Get Focus Event screen.activeform.refresh. Set Closable to false. Set MaxButton to false. Set MinButton to true. Set ShowWindow to 2 - As Top Level Form.
Set WindowState to 0 - Normal. Show Tips = True.
Set Scroll Bars = 0 None. AutoCenter =.T. Check Tab Order. Create Caption! Review the form design guidelines. 4 Your SelectCombo shall have the following 5 options: 5 Your OrderCombo shall have the following 2 options: Create The Search Form 1 Create the following generic Search form with your project manager.
Note that it has the same two combos as were on your Rest form. Think copy and paste! The form title bar is to be Search Engine. Special Search Form Settings and Events. Always On Top =.T. AutoCenter =.T. Caption = Search Engine.
Closable =.F. GotFocus Event = Do SetSearchExample. MaxButton =.F. MinButton =.F.
Name = Search. Show Tips = True.
Set ShowWindow to 2 - As Top Level Form 2 Your Search By choices are to have the following 2 options: 3 Your Group To Search - Select choices are to have the following 5 options: Create The Print Form 1 Create the following generic Print form with your project manager. The combo is to have list of all the reports for your application.
The form title bar is to be Report and Label Selections. The three required options for the PrintCombo are Full Report Professionally laid out report containing all of the information about the restaurant is to go to the printer! and NamePhone Report Professionally laid out report containing only the Name and Phone of all restaurants is to go to the printer and a mailing label for envelopes.
Special Print Form Settings and Events. Always On Top =.T. AutoCenter =.T.
Caption = Print Report and Label Selections. Closable =.F. MaxButton =.F. MinButton =.F. Name = Print. Show Tips = True.
Set ShowWindow to 2 - As Top Level Form Create The Undelete Form 1 Create the following Undelete form with your project manager. Shown in the List box are to be only those restaurants that are deleted. The form title bar is to be To Undelete, Move Cursor Into Desired Row & Select Undelete! Special Undelete Form Settings and Events.
Always On Top =.T. AutoCenter =.T. Caption = To UnDelete, Move Cursor Into Desired Row & Select Undelete!. Closable =.F. MaxButton =.F. MinButton =.F. Name = Undelete.
Show Tips = True. Set ShowWindow to 2 - As Top Level Form Reports 1 Create a full report that professionally displays all of the information of the filtered restaruants with page numbers, dates, and captions.
Put a divider line between each record. Call the report FullReport. Store the Reports in the Report folder. 2 Create a Name & Phone report that professionally displays the name and phone of the filtered restaruants with page numbers & dates. Yoiu may put the captions at the top of the columns if you like. Call the report NamePhone. Extra credit pt If you get the filter information on the report title as well.
SKIP Not Installed On Lab - Labels - SKIP Not Installed On Lab 1 Create a mailing label that professionally displays the Name on line 1 of a label. Display the Address on line 2. Display the City, State, and Zip on line 3 of the label.
Call the label Mail. Beneath The Docs Tab 1 Your application should now have the following forms, reports, and labels. (See Below!) Add Programs To Project 1 Add a main program in which to launch your application and a code file in which to store all of your button code.
All forms and applications should be tested by selecting the Main and pushing the Run button. 3 Using the mouse, right click on main and select Set Main. You may also hold down the project menu and select Set Main. (See Below!) 4 Note that it is now bold. This shall be the program that is run when the executable is built. You must do this in order to create executables. (See Below!) Create A Good Start Program - Main.prg 1 Some of the system variables begin with an underscore.
By convention, I start all of my global variables, declared in main, with a double underscore. It makes them easy to identify. Listed below is a screen capture of one good student's attempt to solve this problem. Depending upon how you implement your solutions, you may or may not need to use all of the same variables. There is nothing new for my students in this block of code. 2 Note that you have to path to the code.prg file that contains all of the button code.
You will also have to path to the database table and the forms.
Foxpro was created in early 80's (originally as FoxBase - 1984?) by Fox software and supported on Mac OS, Unix, DOS, Windows platforms. It was known as the fastest database engine on PCs then. Later on 1992, unfortunately, it was acquired by Microsoft.
After Microsoft's taking over, in 1994 Foxpro for DOS (FPD) and Foxpro for Windows (FPW) 2.6 released. At the end of 1995, Foxpro got the name 'Visual' and the platform support was only limited to windows. It was also the first version of Foxpro where the language turned out to be Object Oriented.
Microsoft's official Visual Foxpro (commonly referred as just VFP) site describes it as: Microsoft® Visual FoxPro® database development system is a powerful tool for quickly creating high-performance desktop, rich client, distributed client, client/server, and Web database applications. Although it is an old language, it is still considered to be the easiest language for creating a data centric application rapidly for the windows desktop. If what you need is to create a data based application for windows desktop then choosing VFP you would really do that easily and fast. Version Released FPW 2.6a 1994-10-28 Visual Foxpro 3.0 1995-12-16 Visual Foxpro 5.0 1997-01-24 Visual Foxpro 6.0 2000-08-18 Visual Foxpro 7.0 2002-01-04 Visual Foxpro 8.0 2003-10-25 Visual Foxpro 9.0 2004-12-13 Visual Foxpro 9.0 SP2 2007-10-21 Add Global Error Handler A simple way to catch unhandled errors (exceptions) in a VFP application is to use the ON ERROR command near the beginning of your main program. The following ON ERROR command calls a method in the current program called 'errorHandler'. The values returned by ERROR (the VFP Error Number), MESSAGE (the VFP Error Message), PROGRAM (name of the currently executing program) and LINENO (the line number of the error) are passed to the errorHandler method. ON ERROR DO errorHandler WITH ERROR, MESSAGE, PROGRAM, LINENO A simple errorHandler method may look like the following.
PROCEDURE errorHandler LPARAMETERS tnVFPErrorNumber, tcVFPErrorMessage, tcProcWithError, tnLineNumber STORE 'Error message: ' + tcVFPErrorMessage + CHR(13) +; 'Error number: ' + TRANSFORM(tnVFPErrorNumber) + CHR(13) +; 'Procedure with error: ' + tcProcWithError + CHR(13) +; 'Line number of error: ' + TRANSFORM(tnLineNumber) TO lcDetails MESSAGEBOX(lcDetails, 16, 'Unhandled Exception') ON ERROR. ON SHUTDOWN CLEAR EVENTS QUIT ENDPROC You can also change and restore the error handler in between. For example, at one point you want to open all tables in a folder exclusively, and if you can't you don't want to continue: procedure DoSomethingWithExclusiveLock(tcFolder) local lcOldError, llInUse, ix && by default these variables have a value of.F.
LcError = on('error') && save current handler on error llInUse =.T. && new handler local array laTables1 for ix=1 to adir(laTables, addbs(m.tcFolder) + '.dbf')) use (addbs(m.tcFolder)+laTablesm.ix,1) in 0 exclusive endfor on error &lcError && restore old handler if m.llInUse && couldn't get exclusive lock on all tables close databases all return endif.
do whatever endproc Tip: Sometimes, especially during debugging, you would want to restore default error handler which allows you to break and step into the code where the error has occurred, then anywhere before where you got the error, temporarily adding: on error would do this. Hello World In all languages traditionally the first example is printing 'Hello World'. Probably doing that is easiest in VFP:?
