The initial assignment was to attempt to provide more efficient luminescent. Just before ReDim() generates an IMA, the memoryusage of this process growes up to over 800 MB (observed with TaskManager) - even though ReDim() should only increase the Size to 6000 Fields (600MB). Was there any one that stands out in your memory. my System ReDim() generates an IMA while trying to allocate 600 MB. MessageRequester("Memoryallocation by Dim() Test",Str(n /100)+" MByte allocated by 'Global Dim'."+#CRLF$+"Testvalue: "+Str(Test(n-1)\BigSpace)) I haven’t really used it in Windows, so I can’t say for sure, but from a quick investigation online it looks like each instance of popen in the sample code should be replaced with either popen or wpopen (the second one. In Windows, I think the popen function works differently. and secondary module files get loaded into the memory, when main file runs. Each module has a unique name and interfaces are used to combine these modules within a Will reserve 100KB for each structured Elementįor n = 5000 To 16000 Step 1000 This Loop will reserve between 500 MB and 1.6 GB of Ram in 100 MB Stepsĭebug "Trying to allocate "+Str(n / 10)+" MByte." : Debug ""ĭebug "Allocating Block "+Str(m/1000)+" - Arraysize is now "+Str(m / 10)+" MByte" A distant memory is slowly coming back to me. Computer functionality generally depends on two structures- software. It is not necessary for a programmer who is working on one module to have knowledge about other modules. There will be very little or no dependency within various modules. Different modules are assigned to various programmers in a team so that each programmer has to work on a particular module that will perform certain operations. The modular programming approach was basically developed to maintain complex programs,ĭuring software development. Simplify collaboration for different modules Advantages of modular programming involve:ĭivision of big program into sub-programs The division of big programs into small modules increases the team work efficiency, maintainability and the quick debugging. Sometimes modules are identified as: sub-routines, macros or sub-programs. The key idea is to divide a gigantic program into small modules and each module has its own functionality, meaning the operations it has to perform. To manage these types of issues, modular programming comes into existence. Many software programs consist of thousands of lines of code it is quite challenging to analyze any semantic and syntactical errors within it. Modular programming is an approach to software development in which various independ ent codes are implemented in a way that the operations they are going to perform will be collaborated easily and can be reused. Modules are generally interoperable so that they can interact with other modules or functions within a program without a programmer. Interoperability: It is the ability of a program or function to communicate with other functions to achieve higher efficiency. This will be very helpful while developing a complex software program on which multiple teams work, with different operating systems. Portability: Modules allow a code that is developed in one environment with a specific operating system, to be ported to a new platform without developing it again. I am using my ReDims inside of procedures and they involve a lot of strings if that makes a difference (shouldnt). One can reuse the same code with a different approach within a program. When I check the Windows process list, my memory usage increments upward each time using Redim, but not if I clear arrays manually. Modules can help the programmers avoid typing or copying/pasting a single code, multiple times in a program. as far as I see it my options are a) PBs linked lists commands, and b) manual memory allocation (using either PBs AllocateMemory, or the WinAPIs heap functions). The most important reason people chose Pascal / Object. Im trying to think of the best way to do this in PB. Reusability: While developing enterprise-level software, modules are implemented to make it simple, easy to understand and can be used over and over, again. Pascal / Object Pascal is ranked 8th while PureBasic is ranked 24th. scCreateILockBytesOnHGlobal(Null, True, lpLockBytes) If sc This means that the allocation failed. Is it possible to free the memory used by the images. During implementation or debugging, it is quite simple to access or test a single module in one go, rather than accessing the whole software program. PureBasic Expert Posts: 10589 Joined: Wed 3:35 pm. These modules are then implemented within a big program with the help of interfaces. Programmers have to focus on a single area of code, not on thousands of lines of code. Easy to Use: Modules make complex software simple to use and check.
