  • Small Command line scripter (like Autocad commands) one line editor

    - by Objectsberg
    Basically I don't know from where to start, I need to add a line script for my application that is not so complicated, just to execute pre-defined commands, for instance: command New Invoice -- create new invoice command customer profile -- open customer form where cust id = CustID command run End-Of-Day - run the end of day process command scr 1020 -- open form id = 1020 How can I start? I have no problem of recommending any third party components (parsers,evaluators,etc..). whats missing is the basic structure no details, just a theory for implementation. Thanks, Objectberg

  • Send array of string using tcp

    - by user2798455
    I'm not sure if this is possible but here it goes. Usually I send strings like this... Connection.IOHandler.WriteLn('alpha'); Connection.IOHandler.WriteLn('bravo'); Connection.IOHandler.WriteLn('charley'); //and so on.. But what if I want to send it in just one go, just send it all at once. Maybe I could put it on an array of strings then send the array. someStr : array[1..3] of string = ('alpha','bravo','charley');//this could be more ... StrListMem := TMemoryStream.Create; try StrListMem.WriteBuffer(someStr[0], Length(someStr)); StrListMem.Position:=0; Connection.IOHandler.Write(StrListMem, 0, True); finally StrListMem.Free; end; I just have no idea how to this right, maybe somebody can give an example? and how the receiver(client) will read it.

  • Dynamically add tab sheets to page control and embed a form?

    - by Jerry Dodge
    I'm working on a module which consists of a page control. By default, this page control (TPageControl) shouldn't have any tab sheets (TTabSheet), but upon initialization, it should dynamically insert these pages and embed a form inside of it. The issue comes with knowing how to insert a tab sheet into the page control. How do I create this? And once it's created, along with the forms inside each one, how do I iterate through them to destroy the forms?

  • How to merge two menus in a MDI application.

    - by Altar
    Hi. Anybody knows how to merge two menus with the same name in a MDI application. More exactly, in the MDI main form I have a menu called 'File' which has a sub-menu called 'Load project'. In the MDI child form, I have a menu called also 'File' which contains a sub-menu called 'Save project'. How can I force my application to show both 'Load' and 'Save' sub-menus under the 'File' menu? - PS: setting the same GoupIndex value will not work.

  • How to get a float value the pointer points to?

    - by aleluja
    Hello, In my app, i've created the TList type list where i store the pointers to 1 string and 2 float(real) values for every 3 items. aList.Add(@sName); //string aList.Add(@x1); //float aList.Add(@x2); //float Then, i want to get the values out from the list, but i could only do that for string sStr := string(lList.items[i]); But i couldn't get the float values as a := real(lList...) will result in an invalid typecast error. So what do i do to get the float values? Of course i have a question if that string casting will actually give me the string value. I'm not good at pointer stuff so i don't know how to do it.

  • Using TXMLDocument to serialize form settings to XML and database.

    - by LukLed
    I have an interface: type IXMLSerializable = interface function SaveToXML : DOMString; function SaveToXMLDocument : IXMLDocument; procedure LoadFromXML(AXML : DOMString); end; It is used to serialize some settings of forms or frames to xml. Simple implementation: SaveToXMLDocument: function TSomething.SaveToXMLDocument: IXMLDocument; begin Result := TXMLDocument.Create(nil); with Result do begin Active := True; with AddChild(Self.Name) do begin AddChild(edSomeTextBox.Name).Attributes['Text'] := edSomeTextBox.Text; end; end; Result := XMLDoc; end; LoadFromXML: procedure TSomething.LoadFromXML(AXML: DOMString); var XMLDoc : IXMLDocument; I : Integer; begin XMLDoc := TXMLDocument.Create(nil); with XMLDoc do begin LoadFromXML(AXML); Active := True; with ChildNodes[0] do begin for I := 0 to ChildNodes.Count-1 do begin If ChildNodes[I].NodeName = 'edSomeTextBox' then edSomeTextBox.Text := ChildNodes[I].Attributes['Text']; end; end; end; end; SaveToXML: function TSomething.SaveToXML: DOMString; begin SaveToXMLDocument.SaveToXML(Result); end; DOMString result of SaveToXML is saved to database to blob field. I had some encoding issues with other implementations and this one works fine (right now). Do you see any dangers in this code? Can I have issues with different settings on various machines and systems?

  • How reduce dll size again

    - by cemick
    My dll have been bigger multiplied up many times than early for some reason. I begining to size up the situation: A source hasn't changed. Debug information everywhere turned off. Dll use package "Pack", but not include in Runtime Packages options. I've compared new dll with old version dll thought the instrumentality of PE Explore. In new dll I find out many modules with prefix 'ec' implicitly imported unlike old dll. Package "Pack" using ecControls components Dll doesn't using explicitly call to ecControls units. Why ecControls units imported in dll? Have anybody some advice?

  • How to make TObjectDictionary.Values accessible as property?

    - by Holgerwa
    I have an object like this: TMyObj = class private FObjList: TObjectDictionary <integer, TMyObject>; public constructor Create; destructor Destroy; // How to access Values correctly?

How do I need to declare the property "Values" so that MyObj.Values behaves exactly as if I would access MyObj.FObjList.Values?

  • Array with mutiple types?

    - by aleluja
    Hello, I was wondering if there is a way to make an array which would have mutiple types of data fields. So far i was using aMyArray: array of array [0..1] of TPoint; But now, it is not enough for me. I need to add 3 more elements to the existing 2 "Point" elements making it an array like aMyArray: array of (TPoint,TPoint,real,real,real) So each element of aMyArray would have 5 'children', 2 of which are of a TPoint type and 3 of them are 'real' type. Is this possible to implement somehow?

  • EUpdateError exception not recognized when raised in TDatasetProvider.OnUpdateError. Why?

    - by max
    When I re-throw a EUpdateError exception in the TDatasetProvider.OnUpdateError event, it is not recognized as EUpdateError exception in the catch block. It's only recognized as base Excption. try ... //calls the TDatasetPorvider.OnUpdateError event. myClientDataSet.ApplyUpdates(0); ... except on ex: EUpdateError do begin //never goes here //Evaluate ex.ErrorCode end; on ex: Exception do begin //always goes here //the expression (ex is EUpdateError) returns false; end; end; Hiere is the corresponding .OnUpdateError implementaion: procedure MyDataModule.MyDatasetProviderOnUpdateError(..;E: EUpdateError;...); beign //Here, the expression (E is EUpdateException) returns true; raise E; end; The exception is re-thrown, but as it seems the EUpdateError is transformed into a plain base Execption. Does anybody know, why the class type get lost? I would need that type in order to check the .ErrorCode to know what went wrong and to prepare the proper user message.

  • How to check if TypeIdenitifier(T) is an Object?

    - by John
    I'm creating a generic list class that has a member of type Array(Array of ). The problem is the class descruction,because the class is supposed to be used for types from byte to types inheriting TObject. Specifically: destructor Destroy; var elem:T; begin /*if(T is Tobject) then //Check if T inherits TObject {Compiler error!} for elem in FData do TObject(elem).Free;*/ // do not know how to do it SetLength(FItems,0); //FItems : Array of T inherited Destroy; end; How do I check if T is TObject so I can free every member if the typeidenitifier is a class,for example?

  • Where does the data model go in a Prism app?

    - by HawkeyeJoeS
    I'm having trouble where to put our data model in our Prism app. Most, if not all or our data will be coming from web services and the web services are unique for each module. Unfortunately, there will be objects that need to be shared (such as a person/user object). I'm really torn about whether to add these services directly to the module, so that each is truly independent, or create a separate project to house the web service proxies and business entities. The modules are being built by different teams, but will all live in the same solution (and source control, of course).

  • Delphi dbExpress and Interbase: UTF8 migration steps and risks?

    - by mjustin
    Currently, our database uses Win1252 as the only character encoding. We will have to support Unicode in the database tables soon, which means we have to perform this migration for four databases and around 80 Delphi applications which run in-house in a 24/7 environment. Are there recommendations for database migrations to UTF-8 (or UNICODE_FSS) for Delphi applications? Some questions listed below. Many thanks in advance for your answers! are there tools which help with the migration of the existing databases (sizes between 250 MB and 2 GB, no Blob fields), by dumping the data, recreating the database with UNICODE_FSS or UTF-8, and loading the data back? are there known problems with Delphi 2009, dbExpress and Interbase 7.5 related to Unicode character sets? would you recommend to upgrade the databases to Interbase 2009 first? (This upgrade is planned but does not have a high priority) can we simply migrate the database and Delphi will handle the Unicode character sets automatically, or will we have to change all character field types in every Datamodule (dfm and source code) too? which strategy would you recommend to work on the migration in parallel with the normal development and maintenance of the existing application? The application runs in-house so development and database administration is done internally.

  • Should I use MEF or Prism for my Silverlight project?

    - by Daniel
    Hi! My team(3 developers) will be building a Silverlight LOB application. This is the first Silverlight project for us. We've been doing mostly Winforms. We'll be using Silverlight4 / VS2010 / possibly WCF RIA Services, and ASP.NET Web application to handle authentication and host the silverlight pages. We need a way to.. Modularize the silverlight project so we can work in different parts of the application, then integrate them. Dynamically load different parts of the application, so the initial download size of the xap file wouldn't be too large. After some research, I found out that Prism and MEF are possible solutions to these goals. Can you give me advice on which framework to use? or possibly another solution? We don't have much experience on Silverlight and the project needs to be finished in 3 months, so the learning curves for frameworks should be considered. Thank you for reading! Any inputs will be much appreciated.

  • MVVM framework AND Prism 4?

    - by Karsten
    I just read this question. It has some nice answers, but they are over 1 year old, and a lot have changed in this space over the last year. Some of the most popular frameworks have come out in a new mayor release such as Prism and MVVM Light Toolkit. My question is somehow the same, but with one twist, I'm already using Prism 4.0 because of the region and module features. Prism 4.0 embraces MVVM, but I feel there are something which are "not lightweight", for instance interaction requests. So I'm thinking would it better to use another MVVM framework either as a substitute or a supplement for Prism 4.0?

  • What is The Loop Variable After a For Loop in Delphi?

    - by Andreas Rejbrand
    In Delphi, consider var i: integer; begin for i := 0 to N do begin { Code } end; One might think that i = N after the for loop, but does the Delphi compiler guarantee this? Can one make the assumption that the loop variable is equal to its last value inside the loop, after a Delphi if loop? Update After trying a few simple loops, I suspect that i is actually equal to one plus the last value of i inside the loop after the loop... But can you rely on this?

  • Is it possible to tweak TStringField to work like TWideStringField in Delphi?

    - by mjustin
    We want to use Unicode with Delphi 2009 and Interbase, and found that to switch the character encoding from WIN1252 to UNICODE_FSS we first have to replace all instances of TStringField with TWideStringField in all datamodules. For around 60 datamodules, we can not simply do this over one weekend. I can see only two options for a migration strategy: find a workaround which allows to use the existing TStringField fields without triggering the 'expected: TWideStringField' error or remove all persistent fields to avoid the string type conflict As far as I know the field types for persistent database fields are registered in some kind of class registry. Could we use this to make Delphi believe that a TStringField is ok for a Interbase character column with UNICODE_FSS encoding? Or can we use a commercial dbExpress driver which work with TStringField in both cases? See also my related question: http://stackoverflow.com/questions/2302670/delphi-dbexpress-and-interbase-unicode-migration-steps-and-risks

  • What is the best method for implementing mouse wheel activity in Delphi VCL forms?

    - by Brian Frost
    As a long time user of Delphi 7, I've rolled my own mouse wheel handling in a few controls but lately I've noticed that some recent applications only need the mouse cursor to be placed over a control (e.g a list box or tree view) for the mouse wheel activity to cause that control to scroll. This feels nice (as opposed to having to click focus a control before it responds to the wheel. Now I've moved to Delphi 2010 I'm wondering what is the 'correct' behavior? And what can I use in Delphi that avoids me having to bodge this with my own solutions now? Thanks.

  • Delphi, What do I do about "no GetEnumerator present" error when using a for loop over Excel Interop

    - by Ryan
    Hello, I'm trying to write a Delphi program that will loop through each worksheet in an Excel file and format some cells. I'm receiving an error while trying to use the for-in loop over the Workbook.Worksheets collection, though. The error is specifically: [DCC Error] Office.pas(36): E2431 for-in statement cannot operate on collection type 'Sheets' because 'Sheets' does not contain a member for 'GetEnumerator', or it is inaccessible The line of code this occurs for is: for Worksheet in Workbook.Worksheets do The definition of Worksheet and Workbook is as follows: var ExcelApp: ExcelApplication; var Workbook: ExcelWorkbook; var Worksheet: ExcelWorksheet; I'm porting this code to Delphi from C#, in which it works. Does anyone know why I'd be getting this GetEnumerator error? I'm using the Office 2007 Excel Interop file and Embarcadero® Delphi® 2010 Version 14.0.3593.25826. Thanks in advance.
