Dynamic positioning method for repeated resource

Abstract

The present invention relates to the re-positioning of resource in system. During installing or applying software, the intercepting module is used to intercept and analyze resource and the resource is called directly when it is not duplication of some resource in available application software or is repositioned by the re-positioning module. Index head corresponding to the re-positioned resource is established and through the index head the application software and other application software can call matched resource for normal operation.

Description

Technical field [0001] The present invention is a dynamic positioning method when resources are repeated. It is mainly to resolve conflicts between application software calling resources with the same name, without modifying the original resources of the application software, and being not limited by resource types. In turn, methods to ensure data stability. Background technique [0002] In the known technology, when a user installs a certain software in a Windows operating system, during the installation process of the installation software, it is necessary to repeatedly apply to one or several dynamic link programs (DLL) in the existing system. The user will be asked if they want to overwrite the old version of the same program address in the existing system (Old Version). If the user chooses yes, the old version will be completely overwritten and the content will be updated to the new version. The version still uses a certain program address of the old version, so the previous...

Problems solved by technology

[0002] In the known technology, when the user installs a certain software in the Windows operating system, the installation software, during the installation process, must be repeatedly applied to one or several dynamic link programs (DLLs) in the existing system. It will ask the user whether to overwrite the old version (Old Version) of the same program address that already exists in the system. The version still uses a certain program address of the old version, so it often causes the previously installed software to be unusable at all, thus affecting other application software already installed in the system, because the dynamic link program (DLL) called by the application software and the The modified dynamic link program (DLL) has a duplicate program address; if the user selects No, the newly installed application software cannot be used normally. The reason is that when the user installs a large number of application software in Windows operations, the The dynamic link program (DLL) with the address of a certain program in the same file between applications often overwrites each other, and only one of the executable programs exists. For example, for users who have Office and VisualBasic installed at the same time, only There is a software that can run normally, mainly due to the duplication of application resources among the application software. Therefore, there are two methods to solve the problem of calling resources with duplicate names in the prior art:

[0003] 1. When there is a phenomenon that a resource with a certain program address is repeated between two application software, when the two application software is installed, a certain program address will be repeated between them. The two versions are backed up separately. When the A application software is to be run, the A.DLL will be called, and when the B application software is to be run, the B.DLL will be called. The application software cannot be used normally at the same time, and no matter which application software is used, it is necessary to use a manual method to call different dynamic link programs (DLL). The operation is very cumbersome and cannot be automated.

[0004] 2. When the two application software of A and B conflict, analyze its executable file structure (PE format), make it relocate to a resource, such as figure 1 As shown, modify the A.DLL that is called by both application software A and B into one being C.DLL and the other being A.DLL, that is, modifying the module table in the PE format, but using this The method can only be operated manually, and cannot achieve an automated process, and can only ensure that the modified object is an executable file (that is, a file with PE, NE, LE format), so it is a static positioning method, and its operation requires Modifying the original file code does not guarantee the relocation of other types of resources, so the stability of the program cannot be guaranteed
