RESCUE FOR 4D DOCUMENTATION - Resource Crossing

RESOURCE CROSSING

Introduction :
The Resource Crossing option is one of the most powerful of Rescue for 4D. It allows you to do inter-resource checks. It has two main functions :

Very little 4D resources are independent. Resources are, for the most part, closely tied between them to form a tree of objects (internal resources). If only one of the resources of this tree is lacking or damaged , this can generate serious malfunctioning, and perhaps a bomb. And the risks rise with the size of your database. Hence it is very important to use this option often, to quickly notice possible problems, and to correct these problems. Of course, not all links are of major importance. This is why Rescue for 4D only checks those which can generate problems.
Because of the complexity of this tree, it is possible that 4D, when deleting of a "parent" resource, does not delete the children. This will not generate problems, but it will make your structure unnecessarily large.

Checkings & Actions :

A structure with several overlapping trees will demand many tests to check its validity. The lack or incoherence of only one element in the tree can generate serious problems. Doctor considers all these relations and this is why it is important to check the structure several times after correcting a defective element. The reason for this is that one correction can generate a problem elsewhere in the structure.
For each problem, there is a solution. And Doctor always chooses the best solution with regard to the problem and the resource type which need correction. Some resources are essential for 4D to properly function. Theses resources are indicated in the following table.
As corrections can generate many changes in a structure, detailed messages are displayed so you can better understand the problems encountered.

To help you, the following table contains explanations for each Type.

MEPI : this resource type contains the pictures you have pasted in menu bars.

Checking : checks whether there is a menu bar for this picture. Correction : the correction will delete the resource.

LIBA : this resource type contains the ID for each menu bar (BA4D) in order. This is an essential type for the functioning of 4D.

Checking : checks whether, for each ID, there is a resource BA4D. Correction : the correction will delete the link with the menu bar (4D will no longer see it ; but, as it didn't really exist...).

BA4D : this resource type defines menu bars. It contains the ID of each menu (MEN4). This type can be essential for 4D if the menu bar number is 1.

Checking 1 : checks whether, for each ID, there is a resource MEN4. Correction 1 : the correction will delete the link with the menu bar (4D will no longer see it, but as it didn't really exist...).

Checking 2 : checks that the ID is actually present in the resource LIBA d'ID 0. Correction 2 : the correction will delete the resource BA4D (4D will no longer see it, but as it didn't really exist...).

WN4D : this resource type contains the name of each table, in order of creation. This is an essential type for the functioning of 4D.There can only be a problem here if the resource does not exist.

Checking : None. Correction : None.

MEN4 : this resource type contains the menus definitions (title, line, style, associated procedure, etc). This type can be essential for 4D if the menu bar number is 1.

Checking : checks that the ID is actually used in one of the BA4D resources. Correction : The correction will delete the resource MEN4 if it does not seem to be used by 4D.

LE4D : this resource type contains the enumeration name of the database and also the ID of the resource EN4D (v5) or List (v6) which contains the enumeration itself.

Checking : checks that each ID really exists in the type EN4D/List. Correction : None

EN4D (v5) / List (v6) : this resource type contains the enumeration lines.

Checking 1 : Checks that the enumeration is tied and if it really exists. Correction 1 : The correction deletes the link.

Checking 2 : Checks that the enumeration is really used by the resource LE4D. Correction 2 : The correction will delete the resource if it does not seem to be used by 4D.

CC4D : this resource type contains the code for your software (Procedures, scripts, Layout Proc., Table Proc., etc...).

Checking : checks whether each ID actually exists in the type TP4D. Correction : No correction made and no warning. In fact, this test IS INCOMPLETE and will remain so until Rescue for 4D recognizes the internal structure of FO4D. However, this checking will display the name of the associated procedures in the Editor.
