[V4CC][NEW] DataSource for VCursor and VTable classes.

NSTableView class has setDataSource method that allows assign a NSTableDataSource instance to be a data source for that table view.

In v4.8 we have to add VCursorDataSource and VTableDataSource classes that are able to do this job — easy display a cursor or a table into a given NSTableView. As easy as a single line of code:

mCursorDataSource = [[VCursorDataSource alloc] 
                         initWithCursor:mCursor view:tvListBox];

[V4CC][NEW] KVC for VCursor and VTable.

In v4.8 we adding support of Key Value Coding (KVC) to VCursor and VTable classes.

This is implemented as VCursor (KVC) category with a couple of methods:

@interface VCursor (KVC)
                // If wrong key is specified then nil is returned.
- (id)		valueForKey:(NSString *)key;

                // If wrong key is specified then nothing is changed.
- (void)	setValue:(id)value forKey:(NSString*)key;

[V4CC][New] Extended Support of Cocoa and Obj-C Features

In v4.8 of Valentina for Cocoa we greatly improving support of Cocoa and Obj-C 2.0 features. For this we have add  V4CC/sources/cocoa folder, which contains all additional code for this. In such way, we keep very separate standard Valentina ADK API sources and this additional features sources.

OS X Loads DYLIB from App folder ignoring install_path … Oops?

Our Valentina Studio project has one Application target and dozen of plugins targets. Plugins are made as bundles.
All these targets build products into the same folder “Debug (Native)” or “Release (Universal)”.
Then Run Scripts do copy plugins into App package and using install_name utility correct install paths for them.

XCODE Breakpoints Not Working

Yesterday I have decide to resolve problem with absolutely not working breakpoints in the XCODE 3.2.3 on OS X 10.6 (may be others also) working with our Valentina Studio project.

In the past we also did have such problems, but not so bad. Breakpoints did work sometimes, in worse case we was able to insert DebugStr(“\p”) into code, and that 100% did stop in the debugger as for app, so fot its plugins and for database engine DYLIBs.

And yesterday I have to see the first time that even DebugStr() do not stops. Wow.

I have spent many hours googling about this problem. And have found few key places.

NOW V4CC/iV4CC Works with GarbageCollection-enabled apps also

For this we just have set option GarbageCollection = SUPPORTED for V4CC (32/64)  and iV4CC (Dev/Sim)  targets. This means that now these frameworks will work in both kinds of apps: GC-enabled and GC-not-enabled.

Note, that internally V4CC still uses retain/release. Also keep in mind that we very recommending to developers manage lifetimes of database objects manually. Just image that you have allow to GarbageCollector manage a VCursor instance. When you think record locks will be released?

REAL SQL Server To Leave REAL; Time to Switch to Valentina

I was not entirely surprised to read on the REALbasic NUG that REAL SQL Server would no longer  be a REAL Software product but would go back to its original developer, SQLabs. Even with the bundling options available with REALbasic, a database product that cannot differentiate itself cannot survive. Now there is even a special offer for disenfranchised REAL SQL Server users until October 10, 2010. Continue reading REAL SQL Server To Leave REAL; Time to Switch to Valentina

[NEW][API] Valentina.CopyCursorToNewTable()

We introduce a new utility method Valentina.CopyCursorToNewTable(), which is able to save you hundreds of lines of advanced code in your ADK-based applications. This method added into major Valentina ADKs.

You can read detailed description of this new method here.

Welcome VistaDB .net Developers to Valentina DB

We recently heard that the company that owns VistaDB, a .net focused database system, has closed their office in Florida and looking for ways to sell off their database product. Paradigma Software invites VistaDB developers to give Valentina DB ADK.net a try – along with a 50% discount if purchased before September 1, 2010.

All you have to do if you are a VistaDB user is to order Valentina DB ADK for .net before September 1, 2010, and insert “VistaDB: YOUR SERIAL CODE” into the customer notes field to save 50% – get this ADK for only $99.95.

[NEW] 64-bit ADK added to MAC OS X: C++, Cocoa, PHP

We introduce our first 64-bit ADKs for MAC OS X:

  • Valentina for C++ (VSDK)
  • Valentina for  Cocoa (V4CC)
  • Valentina for  PHP Standalone (VPHP)

It is clear that we cannot make V4RB, V4REV and such to be 64-bits because their IDEs do not support this.

Next our step in this direction, will be introduction of 64 bit ADKs for Windows, VSDK, VNET, …

Changes in Valentina for Cocoa API.

Erne have report bug http://www.valentina-db.com/bt/view.php?id=4885 in Valentina for Cocoa (V4CC).

Problem was that VField.value in ObjC implemented as pair of methods (in other Valentina ADKs, e.g. Valentina for REALbasic it is a true property of class). So if to override this pair in the sub-classes then always will be called overridden methods.

To resolve issue, we have decide to rename these methods in all VField sub-classes. Rules now are simple:
