bpl modem

BPL English full name Borland Package library is a special DLL file that is used for code reuse and for reducing executables. When compiling BPL, you only need to add the appropriate PAS file for the feature, and if you have a form, you need to add the DFM file. Since it is a DLL file, that is the file that is required at run time. BPL equivalent to DLLs in C + +

In the process of developing a lightweight container Based on Dynamic proxy, it is necessary to dynamically load external custom interfaces, classes, and component functions. You cannot determine whether to use DLL or BPL as the implementation method of custom components. Some technical details were found during repeated tests, especially when the string type was used as a parameter or return value. Anyone who has developed DLL using Delphi knows that

Some time ago to study the development of the BPL way, just recently there is a small project, so try a bit, the project has been completed. Have some experience and experience, write down with you to share, please put forward insufficient, in addition, in the study of BPL friends, there are problems can be discussed together, in order to go faster. A summary of a project (Exe+

[Original] That is correct. a BPL is a DLL. (but not all DLLs are bpls .) > But I still found some different, such as that I can create> Object from the host EXE and that pass to a BPL and modify it safely,> If I do same to a DLL, I can not modify any referenced property of the object. When you use packages, There is only ever one copy of any unit inMemory. One copy of forms, one copy of sysutils, one copy

Previously, for the differences between BPL and DLL, it has always been a comprehensive solution, most of which (I have read), even if it is better than the typical Delphi solution, it's also vague! Thanks to the help in finding a better description !!! That is correct. a BPL is a DLL. (but not all DLLs are bpls .) > But I still found some different, such as that I can create > Object from the host

1. Introduction of various files in Delphi and their relationships. OXC: ActiveX control. It will be installed in a component package dpk. in imports, three files are created: Pas, DCU, and DCR. DLL: the dynamic link library file. Its exports can be written in either the project file or the unit file. There is no difference. Dpk: component package file, which is composed of multiple components (PAS. BPL: the package file is actually a DLL file, but so

For the BPL package, I personally understand is: is a package, and Dll,exe similar, put the code in the package to save it.First, talk about how to create a BPL package1. Open the Delphi IDE (Delphi7 for example)-->file-->close all (off all)-->file-->new-->other--> in the New Item tab (new)-->package-->ok;2, click OK, Delphi helped us to create a number of packages needed for the basic things, such as,At th

Once heard that "BPL is a special kind of dll", but did not think that this sentence has so much significance. Recently, I was surprised to see someone write the export statement in the unit belonging to a dpk. But all the help of Delphi, and export related is the library. Today read the "Delphi Source code Analysis", just know the meaning of this sentence. So there is the following corollary: For DLL engineering, exports can either be written in eng
