Hi there,, , Does anyone know how to clear the text dispplayed in a combo box? Mine just holds the last value and doesn't overwrite it when I tab back to it ideally I want it cleared and ready for the next entry. , , I've tried setting .Text := ''; but it doesn't work even if I set it to '1'; it doesn't display a 1 only the previous value. The whole text line seems to be higlighted rather than just the text. Any ideas?, , Thanks, Mully

I hope this is not the wrong group. Our problem is compatibilty with Paradox application and a delphi app using BDE. Each have their own private directory and more often than not, the delphi app crashes when trying to set the session private directory. Why would this be? The directory is empty and not used by any other application? A reboot of the computer typically solves the problem but I'd really like some further understanding...exception number  : 1, exception class   : EDBEngineError, exception message : Directory is busy., , main thread ($b9c):, 005eb8b1 +011 rcurt.exe Bde.DBTables           DbiError, 005eb8bd +005 rcurt.exe Bde.DBTables           Check, 005ef5e0 +04c rcurt.exe Bde.DBTables           TSession.SetPrivateDir, 0065b89b +8b7 rcurt.exe f_main       1286 +138 TMain.FormCreate,...

Hello and happy new year to all. I am currently in the process of writing a Point-of-Sale, POS, system. I have seen many in person recently and they have fairly simple screens with a few options usually per screen and perhaps some tabs. Color is usually present but not usually overdone. My question, I noticed they all have a gradient type of button in several formats and how do you th ink I should best approach my project to achieve a nice graident button and controls. Here is what I have looked at thus far. 1) Skinning. If I find nothing else, this is the area I will probably land. When I am finished with my research, I will post my findings. Through skinning, I can apply a theme to the Delphi application and at least get a completely different feel than the basic application colors with very little coding. 2) HMI (Human Machine Interface) I do not know much about this, yet, but this seems to be an option. 3) Just DIY, or do-it-yourself - create nice gradient designs in a paint...

So yesterday, all was well, happy happy joy joy. Today...when I try to open up my database program...I get an error, Cannot write to Engine configuration file BDE Error 8453 [$21] [$5]. Same problem when I open BDE Admin - System configuration file not found. System default in use. When I try to recreate the Alias and save the settings, same error, Cannot write to Engine configuration file. So my question is..what happened to the configuration file? I still have the new config file that I created previously, but when I try to apply it to the Alias, same error. I still have the default idapi32.cfg file. But when I try to make a new Alias with that config file, and save it as ParadoxTest (which is the name of the Alias I was using before), it won't let me save. Also will not let me save a newly created .cfg file. Any ideas?, , Using Delphi 6 enterprise with paradox 4.0 tables. Windows 98. .pas .dpr etc files on a Novel network drive, .cfg file is on the same network drive in different di...

I am having problems changing the sort order on a DBgrid at runtime (I am using paradox tables). I have pre-defined an index for each field I wish to sort on (in ascending order)., , I can change which column to sort on by clicking in the column title without problems, but changing the ascend/descend order does not work., , I have stepped through my code and the index definition appears to be getting changed correctly but it seems to lose the change when the Indexdefs are updated or the table is reopened. Here is my routine that is called from the OnTitleClick event., , procedure TTimeSeriesForm.Descend(DoDescending: boolean; Column: TColumn);, var, I: Integer;, begin, CatGrid.DataSource.DataSet.DisableControls;, with Datamodule2 do, begin, CSR.Close;, for I := 0 to CSR.IndexDefs.Count - 1 do, if (CSR.IndexDefs.Items.Fields = Column.FieldName) then, begin, if (Not DoDescending) then, CSR.IndexDefs.Items.DescFields :=...

Am using CodeGear 2007 Win32 with dBase, ACE Reporter, Woll2Woll, JEDI components; therefore I have a lot of TTables and TQueries throughout my program. My applciation runs on a 2003 server with XP workstations. The response time to access data (retrieve, post, do SQLs) is horrible. The users are demanding something better. But I don't know what is better. And I don't know what the ramfications are in changing to something better. I sincerely hope that someone can give me recommendations as well as address the difficulty in changing to another database. Thank you so much, Charlie

Dear Sirs,       Hi Mike and all thanks very much for welcoming me to join you at Prestwood premises and communities. I wish you all the best.      I have been using Delphi 5 with Paradox database doing desktop database applications. I plan to move from paradox to something like Advantage Database Server with Delphi.  The reporting tool I have been using is QuickReport that shipped with Delphi 5. Now I am thinking of learning Fast Reports or Report Builder. I have downloaded their demo versions. I am inclined to use Fast reports but have not tested Report Builder.If you can give some opinion about my choice of Fast report on flexibility or the lack of it, please do so.  Rave reports has discouraged me by not showing examples of master/detail reports. You know, I usually have come across Master/Detail(becoming Master of another detail)/Detail i.e MASTER-DETAIL(MASTER)-DETAIL. And I plan to use Client Datasets with Prov...

I'm working with one of Delphi 5's Demos under Coolstuf, an example of using TWebBrowser. I wanted to do a look and feel of the IE5, which I normally use as my default browser. Well, I've accomplished some, but I'm stuck in getting the URL link of the hypertext link in the browser to show in the status bar (I added to the example) when the cursor (mouse) is at/on that word. , , I stubbed out all the events with unique information displayed in the status bar per event so to recognize any hits a cursor movement makes when moved over the word, phrase, or link in the WebBrowser windows. Nothing happens., , In IE5, when the cursor is moved to a word, phrase, or link that has a URL associated with it, that URL is displayed in the status bar., , How to do? How can I retrieve and display the URL from where the mouse is?, , Thanks,, , Tim R.

I've noticed a problem with the OnGetMonthInfo event of TMonthCalendar. , , (IE. MonthCalendar1GetMonthInfo(Sender: TObject;, Month: Cardinal; var MonthBoldInfo: Cardinal); ), , For example, the following code is in OnGetMonthInfo:, , If month = 6 Then MonthCal.BoldDays([1,8],Month);, , This works fine if you bring up the calendar in July, then click back to June. But if you bring up the calendar in June, no bold days. It seems to be designed to always be one click late with the bold days. The OnGetMonthInfo fires, but displays one click later. Bold days only work if you click into them from the increment buttons on the interface. I can't believe that Microsoft got Outlook 2000 to work with this thing, so there must be some way around this., , Does anyone know of a workaround for this annoying deficiency? I've tried firing an OnGetMonthInfo by itself to force the bold days but no luck. Otherwise, I'd like to know of any recommendations for a decent calendar with the bold day...

I have just thought I might move all my delphi stuff onto my 2003 server and then use remote desktop to access it however some of my apps give me a bdertl70 error when trying to open in delphi however the exe runs fine I am Using Delphi 7 Enterprise Is this an issue with server 2003 or do I need to look harder It seems to be apps with multiple tables that give the trouble all these came of a Windows XP Pro Box and worked just fine Thanks Owen

HiI don't get to spend as much time programming as I'd like to, so when I'm on a project, I tend to use a brute force approach, banging on each problem as I reach it, until I break through, often with help from support groups like this one.I'm hoping to do better this time, and get advice ahead of time. I use the Developer Express Quantum grid components, and they do a great job for me. My only problem is if I go back to an older project based on (say) v3 grid components, and I'm now using v4 components, Delphi opens up the code and complains that it can't find the xxxx class, and asks if I want to ignore or cancel. After ignoring a whole bunch of instances of the old component classes, the code looks like a tank has driven through it, and the visual design is shot to heck as well.Worst of all, there is no indication of where a "hole" has been left; one has to eyeball to find them all. These particular components do not allow both v3 and v4 to be installed simultaneously, so things lik...

I am a neophyte programmer. I have figured out how to generate a simple Delphi 7 form with a button in it which will run an executable. , , procedure TForm1.Button1Click(Sender: TObject);, begin, ShellExecute(Form1.Handle, 'open', 'c:\E3238s\bin\E3238s.exe',, nil, nil, SW_SHOWNORMAL);, end;, end., , My problem is I need to know how to access the menus that are a part of this executable. For example how would I access the FILE menu in order to select EXIT.

>We are also toying with Rave report instead of RTF as Rave apparently can output a PDF quite easily. [wp] I think you're on the right track - turning to a reporting tool.  Rave might do the trick, but I've found it kind of hard to work with. I haven't tried to do exactly what you're describing, but I'd be very surprised if my favorite reporting tool couldn't handle it: Fast Report.  Fast Report also does a fine job of producing PDF output.
