RAD Studio 2007 - List of Fixes to Delphi.NET in December Update

By: Chris Pattinson

Abstract: List of 157 fixes (40 from Quality Central) for RAD Studio 2007, Delphi.NET personality in the December Update

QC# Project Area
Delphi.Net IDE\HTML\ASP\Designer
Description: Steps:
When using "composite controls" in the designer the Control does not render correct (it shows as a small square thus being cropped). Once in the design mode, of the control is moved, it will paint correctly, however; toggling to aspx and back to design will again mispaint the control. Open attached project
Click on design tab.
Expected (see attached bmp):
Two textBoxes and a button
Actual:
small little box (composite)
Move the control to the right.
Notice the "actual" control renders

QC# Project Area
Delphi.Net Debugger\Evaluator
Description: Steps:
Format specifiers have no effect in the evaluator. Set a breakpoint on the line marked #1 and run.

Evaluate the following expression.

IntegerVar,h

See the following result.

42

The value expected was 2A or $2A.


program Test;

{$APPTYPE CONSOLE}

var
IntegerVar: Integer;

begin
IntegerVar := 42;
WriteLn(IntegerVar); // #1
end.

QC# Project Area
Delphi.Net Compiler\Language\Overloading
Description: Steps:
In .NET 2.0 the CLR introduced new overloaded methods to System.String.Split. One new overload takes a string array which is ambiguous with the char array version. Compile the following against .NET 2.0.40607:

procedure OverloadSplitTest(S: System.String);
var
splits: array of string;
begin
splits := S.Split([',','.']);
end;

It will now fail with an ambiguous overload error.

QC# Project Area
Delphi.Net IDE\HTML\ASP
Description: Steps:
Hard-coded string in source (see comment from Takeshi Arisawa for specifics).


Original bug description follows:
----------

One Filelist-Entry is not translated
"ASP.NET Files" should be
"ASP.NET-Dateien"		 1. Click on DATEI - ÖFFNEN
2. open the Dateiliste
3. Scroll to ASP.NET Files

QC# Project Area
Delphi.Net Database\dbExpress Metadata
Description: Steps:
#6 - For SqlConnection.GetTableNames the tablescope property is not
being respected for either dbxmss30.dll when you include
tsSysTable in addition to tsTable.

For MsSql you are calling sp_table_rowset which only accepts 1 table type, and not a set of table types. If you specify just tsSysTable then it works.

QC# Project Area
Delphi.Net ECO\IDE Integration
Description: Steps:
please change the layout of the "Select UML Packages for the ECO Space" dialog for localization. "Cancel" button does not fit into the dialog after we translate.
------------
"Cancel" button in ECO's Select Packages wizard is slightly truncated.		 - Open a new ECO WinForm;
- Go to EcoSpace Designer and click a grey folder icon in the lower left corner;
//"Select UML Packages for the ECO Space" dialog opens;
// See the attached screenshot.

QC# Project Area
39104 Delphi.Net ECO\Persistence Layer
Description: Steps:
[QC Short Description]
ECO crashes when selecting data conditionally from SQL 2005 when the number or rows exceeds certain amount.

[QC Description]
Attached is the test project I created. Please correct the connection string in order to connect to your own SQL server.
The EcoSpace is setup to use GUID as the keys; and the only ECO class is named "Class_1" with only one boolean attribute "Active". The winform contains 3 buttons, the "+ 10" would create and add 10 rows to the DB. the "All" would bind the datagrid to the expression "Class_1.allInstances" and the button "Active" would bind the datagrid to the expression "Class_1.allInstances->select(Active)"

1. setup SQL server and generate the schema
2. run the program and add 10 rows
3. check the "All" and "Active" buttons work properly
4. press 2 more times of the add buttons to add 20 more rows
5. check again the "All" and "Active" buttons work
6. close and restart the program
7. the "All" button works but the "Active" button would crash the program with exception "Conversion failed when converting from a character string to uniqueidentifier."

Reset the EcoSpace to use AutoInc as keys and repeat the test would result in exception: "Error executing SQL: SELECT Class_1_ALIAS.ECO_ID, Class_1_ALIAS.ECO_TYPE, Class_1_ALIAS.Active_COL FROM Class_1 Class_1_ALIAS WHERE Class_1_ALIAS.ECO_ID IN (, , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , )"

P.S. my config:
Windows XP SP2 with all updates, BDS 2006 Update 1 with all hotfixes, MS SQL 2005 Express

    47453

QC# Project Area
47453 Delphi.Net IDE\Docking
Description: Steps:
[QC Short Description]
Dock Tabs appear at wrong position

[QC Description]
If for instance in the delivered Default Layout the Object Inspector is unpinned, it's caption appears as a vertical tab on the left of the structure view. Saving this layout, switching to another one and switching back makes the tab appears to the right of the structure view. Reselecting the current layout brings the tab back where it belongs.
QC Entry 47453
 if necessary, copy the factory "Default Layout.dst" from "<program files>\CodeGear\RAD Studio\5.0\bin" to "<Application Data>\Borland\BDS\5.0\" (Borland???) - start IDE - select "Default Layout" - unpin Object Inspector - save current layout overwriting Default Layout - select Debug Layout - select Default Layout exp: Object Inspector tab left from Structure View act: Object Inspector tab right from Structure View - select Default Layout exp: Object Inspector tab left from Structure View act: Object Inspector tab left from Structure View

looks like code parameters are not working for membership provider.

(jpg attached)		 1. Create ASP .NET App
2. On Page_Load function in Default.pas, write following
Membership.ValidateUser(
// exp: ValidateUuser has two parameters, username and password, so expect to have tooltip for "username" after "(" is entered
// act: tooltip for password is displayed

try FormsAuthentication.RedirectFromLoginPage also. Code completion displays the correct parameter, but parameter tooltips are completely wrong.

QC# Project Area
Delphi.Net Documentation
Description: Steps:
The API signature information, such as method signatures, is missing in a lot of the documentation. For instance, the topic "Borland.Data.AdoDbxClientProvider.TAdoDbxDataAdapter.DeleteCommand" doesn't have a description of the method. 1. Go to topic "Borland.Data.AdoDbxClientProvider.TAdoDbxDataAdapter.DeleteCommand" at ms-help://borland.bds5/delphivclwin32/Borland_Data_AdoDbxClientProvider_TAdoDbxDataAdapter_DeleteCommand.html. Note there is no line with the method signature.
2. By contrast, look at the topic "TCustomActionCombo.DragDrop Method" at ms-help://borland.bds5/delphivclwin32/ActnCtrls_TCustomActionCombo_DragDrop@TObject@Integer@Integer.html. There are lines describing the method both in C++ and Delphi.

Delphi.Net ECO\IDE Integration
Description: Steps:
When creating a WebForm app and a model package at the same time, the initialization of the EcoSpaceUnit fails with a designer error

 1) File | New | Other | Eco | Eco Delphi.Net Project Wizard
2) Select the preset, Webform application and set the checkbox ON for "In separate assembly. click OK
//result:
EcoSpaceUnit opens in the designer with this error:
An error occurred while loading the document. Fix the error, and then try loading the document again. The error message follows:
Could not find type 'EcoSpaceUnit.PersistenceMapperSharer'. Please make sure that the assembly that contains this type is referenced. If this type is a part of your development project, make sure that the project has been successfully built. The variable 'PersistenceMapperSharer1' is either undeclared or was never assigned.
3) In Project Manager, double-click PersistenceMapperProvider.pas to open it
4) Click on the Design tab
//result:
Similar Designer errors
// comment from Jonas:
The project compiles without problems. if you close the project and reopen it, the designer works just fine.

If you create the project with the model in the same project as the rest (uncheck "In Separate assembly"), the same ecospace opens up just fine the first time.

The exception that actually occurs in the IDE is the following:

===
A first chance exception of type 'System.ComponentModel.Design.Serialization.CodeDomSerializerException' occurred in System.Design.dll

Additional information: The variable 'PersistenceMapperSharer1' is either undeclared or was never assigned.

Delphi.Net Modeling\Patterns
Description: Steps:
Delphi.Net and Win32: Stub implementation: don't loose parameter's modifiers.

[Highlander Update]		 1. Original code (e.g. for Win32):
Interface1 = interface
procedure Proc1 (const name: string; Var param1 : Integer; out param2 : Integer);
end;
Class1 = class (TInterfacedObject, Interface1)
end;
2. Now for Class1 generated Stub Implementation. Results:
Class1 = class (TInterfacedObject, Interface1)
procedure Proc1( name : String ; param1 : Integer; param2 : Integer);
end;
So, all parameters' modifiers (const, var, out) are lost and the code is not compilable.

Delphi.Net Modeling
Description: Steps:
Delphi Win32 and .Net: add parameters with var/out/const modifier to global procedure/function using "Add/Remove Parameters for Operation" dialog both to interface and implementation sections. Now only in interface sections parameters with modifiers are partially set.
Adding parameters without modifier happens ok.
Adding paramerters with modifier to procedure/function within a class happens ok.

[Highlander Update]		 1. Source code:
unit Namespace1;
interface
procedure p;
implementation
procedure p;
begin
end;
end.
2. case a. Now select p in Model View and try to change parameters from Object Inspector using "Add/Remove Parameters for Operation" dialog. Add one parameter and set any modifier var/out/const for it - parameter is added to both parts, but modifier is present only in interface part:
unit Namespace1;
interface
procedure p(out param0 : Integer);
implementation
procedure p( param0 : Integer ); // out is lost
begin
end;
end.

2. case b. Using the same dialog as in case a, try to add 2 parameters and modifier set only for first one (it's important that it should be a parameter after parameter with modifier). Result: exception dialog (see attachement).
Resulting code:
unit Namespace1;
interface
procedure p(out param0 : Integer ; param1 : Integer);
implementation
procedure p( param0 : Integer ); // out and other parameters are lost
begin
end;

Delphi.Net Database\DBExpress
Description: Steps:
Putting a TSqlConnection on a VCL.Net form automatically pulls in the unit DBXpress. This is a virtually empty unit, it only contains a uses clause or two. the problem is that it is deprecated, so the compiler will issue a warning everytime it is used.

Holger pointed it out in the first place :)


the reason it is pulled in is because of:

procedure TSQLConnectionSelectionEditor.RequiresUnits(Proc: TGetStrProc);
begin
Proc('DBXpress');
end;

in <tp>\app\dotnetlib\db\Borland.Vcl.Design.DbxCtrlsReg.pas

description of the RequiresUnit:
Should call Proc with all the units that are needed to be used when using this class. The form designer automatically ensures the unit the class was declared in and all its ancestor's units are used in the user's program when they use this component. Sometimes, however, an event will use a type in one of its parameters that is not in its unit nor any of its ancestor's units. If this is the case a selection editor should be registerd that implements RequiresUnits and it should call Proc for each unit that declare the types needed by its events		 new VCL.Net app
drop TSqlConnection on the form
compile

exp: compiles wihtout warnings
act: [DCC Warning] Unit1.pas(16): W1006 Unit 'Borland.Vcl.DBXpress' is deprecated

QC# Project Area
Delphi.Net Compiler\Language\Parameterized Types
Description: Steps:
Generic constraint checking fails spuriously for instantiation of a descendant of the constraint, using another type parameter in declaration of descendant (see example code)

More complicated generic solutions need this flexibility to reduce redundant dependent types when declaring descendants, since .NET doesn't have a typedef-in-template equivalent like C++.		 This program doesn't compile:

Error: E2515 Type parameter 'U' is not compatible with type 'TBaseAlpha<TConcrete<T>.T>'

---8<---
{$apptype console}

type
TBaseAlpha<T> = class
private
F: T;
public
property P: T read F write F;
end;

TBase<T; U: TBaseAlpha<T>> = class
public
F: U;
procedure M(x: T);
end;

TConcreteAlpha<T> = class(TBaseAlpha<T>)
end;

TConcrete<T> = class(TBase<T, TConcreteAlpha<T>>)
end;

procedure TBase<T;U>.M(x: T);
begin
F.P := x;

begin
x := TConcrete<Integer>.Create;
x.F := TConcreteAlpha<Integer>.Create;

For comparison, here's the same program in C#:

}

Description: Steps:
Find a solution to canhas projects with the same structure (names) in one folder.

[Highlander Update]		 1. Create Delphi.Net Package project (Package1) in the default folder for projects.
2. Create namespace (Namespace1) in the project and Class (Class1) in this namespace.
3. Create another project (Package2) in the same folder.
4. Repeate item 2. for project Package2.

Class2 is not created.

AD : SCI asks VFSProject (for 'Package2') to create file with name 'Namespace1.pas' which already exists (in project 'Package1').


Now Class 2 is created and code is Ok.
But when project Package1 is opened, it can be noted that Class 2 is appeared.

Code Folding: incorrect for generic classes/methods

[QC Description]
Code folding is sometimes missing, sometimes misplaced when a unit contains generic classes, interfaces and the methods of their implementations.

There is no obvious pattern to this behaviour, i.e. it is not always the first, second, etc. Neither is it resolved by scrolling and redrawing.

Description: Steps:
[QC Short Description]
class completion duplicates field of qualified type

[QC Description]
When class completion is invoked on a class having a property with a qualified type name (one with at least one dot), the corresponding field is created for each invocation.

This is as mainly seen in .NET where qualified types are common, but also reproducable in Win32.

I actually stumbled across it using ECO where each ECO form has an EcoSpace property of type Eco.Handles.DefaultEcoSpace. Thus each invoked class completion adds another field for that property.
QC Entry 51096
 - start IDE - create new VCL Form Application - move to the public section - enter: "property Foo: System.Int64 read FFoo;" - press Ctrl-Shift-C for class completion - field FFoo: System.Int64 is created - press Ctrl-Shift-C for class completion again exp: nothing happens act: another field FFoo: System.Int64 is created

I wonder how the .Net picked up the publickeytoken when it's not specified in the connectionstring because the publicKeyToken specified in the error message is different from what I have in my gac.

******* See RESOLUTION history		 1) Install Product and Interbase client on a clean VM
2) Run and do a new ASP.NET web application using Cassini

4) Open web.config for the application and change the connection string to be:

<add name="BlackfishSqlAspNet"
connectionString="connectionnName=IBCONNECTION"
providerName="Borland.Data.AdoDbxClient"/>

51423 Delphi.Net Compiler\Language\Parameterized Types
Description: Steps:
[QC Short Description]
Methods with different constraints will not always compile

[QC Description]
Depending on which constraints are placed on methods of a class, the code of one of the methods will or will not compile.

This won't compile:

type
Tester = class
function AreEqual<T: IEquatable<T>>(List: IList<T>;
Index1, Index2: Integer): Boolean;
function Compare<Z: IComparable<Z>>(List: IList<Z>;
Index1, Index2: Integer): Integer;
end;

function Tester.AreEqual<T>(List: IList<T>;
Index1, Index2: Integer): Boolean;
begin
Result := List[Index1].Equals(List[Index2]);
end;

function Tester.Compare<Z>(List: IList<Z>;
Index1, Index2: Integer): Integer;
begin
Result := List[Index1].CompareTo(List[Index2]);
end;

I get the error "undeclared identifier: 'CompareTo'". But the next code will compile, and 'CompareTo' is not undeclared anymore:

type
Tester = class
function AreEqual<T: IComparable<T>>(List: IList<T>;
Index1, Index2: Integer): Boolean;
function Compare<Z: IComparable<Z>>(List: IList<Z>;
Index1, Index2: Integer): Integer;
end;

function Tester.AreEqual<T>(List: IList<T>;
Index1, Index2: Integer): Boolean;
begin
Result := List[Index1].CompareTo(List[Index2]) = 0;
end;

function Tester.Compare<Z>(List: IList<Z>;
Index1, Index2: Integer): Integer;
begin
Result := List[Index1].CompareTo(List[Index2]);
end;

Note that the following will also compile, so is it perhaps that I am doing something wrong?

type
Tester2 = class
function AreEqual<T: IEquatable<T>>(Item1, Item2: T): Boolean;
function Compare<Z: IComparable<Z>>(Item1, Item2: Z): Integer;
end;

function Tester2.AreEqual<T>(Item1, Item2: T): Boolean;
begin
Result := Item1.Equals(Item2);
end;

function Tester2.Compare<Z>(Item1, Item2: Z): Integer;
begin
Result := Item1.CompareTo(Item2);
end;

Hmmm... This also compiles, even with different constraints:

function Tester.Compare<Z>(List: IList<Z>;
Index1, Index2: Integer): Integer;
var
Element: Z;
begin
Element := List[Index1];
Result := Element.CompareTo(List[Index2]);
end;

So how come the compiler can't recognize List[Index1] as implementing IComparable, but it can recognize Element doing that? Actually, even the cast IComparable(List[Index1]) was rejected. Note, if both methods have the same constraint, this seems to be unimportant.
