PAS or DCU files) can be added. File > Open. (select a DPK file, click on Add, and compile) or Component > Install Component. DCLUSR. DPK). A package file has the extension BPL, and is just a Borland- specific version. DLL with added. functions like Get. Package. Info. Table(), ie. Use the Bin\TDUMP. EXE command- line Borland utility to display information. BPL file. Once installed, packages are listed in the Registry under HKEY. For Delphi to find components, they must be located in known directories. Tools > Environment Options > Library. Packages come in three different forms: Those that are design- time- only (ie. Some BPLs are. both design- time and run- time, so I guess they have a switch somewhere in the. From what I understand, a typical situation is thus: if the component offers a design- time interface, this requires installing. BPL in the IDEcompiling this component statically requires compiling some DCUs into. EXE; compiling this component for dynamic loading means reading headers. DCP file, and providing the run- time BPL (which. DCUs that make up this component.)Depending on the . In other words, this is where you decide. EXE, or dynamically. BPLs at run- time. If the packages don't change often, it might be a good idea to use dynamic. EXE for updates. On the other. EXE doesn't use, while, when using statically- linked packages, the IDE will. EXE actually use. In the end, a statically- linked. EXE can turn out to be smaller that a bare EXE and external BPLs. Finally. if resource files are used (RES or DCR), Delphi will need those to compile a. Bitmaps for the components that will appear in the palette. DCR files. The source files, either source (. PAS) or compiled (. DCU) aren't needed to. They are only needed if you want to compile the component yourself. Important: As DCUs are version- dependent, a package can only be installed. IDE that was used to compile it. That's the reason. IDE. The alternative for commercial components. IDE that they wish to support. Moving a design package to another host requires copying the following files. BPL, DCP, possibly DCR resources files, hitting the Component > Install Packages. Add. In addition to individual packages, it is possible to create a package collection. DPC) to make it easier to distribute the different files that make up a package. This type of file requires a Package. Collection Editor (PCE), which is a source file used to define a DPC file. A. DPC file is created through Tools > Package Collection Editor. More information: Questions. If the independent DCUs and the ones aggregated in a run- time BPL are. DCUs. that developers who want to use dynamic linking will compile themselves. BPL? When using a design- time package, I am provided with a BPL that will. In addition, DCU files are required to allow for. On the other hand, when using a run- time package, the package. DCP since it is required to let the compiler know. BPL file for dynamic loading. Correct? When creating a package that is both a design- and run- time package. BPL files, or is there some kind of switch in the. Or are design- time BPLs and run- time BPLs two totally different. How can I tell if a BPL is design- time or run- time? Because the IDE. will complain if I try to a run- time package to the list of design- time. Making sense of extensions. Extension. Acronym. Role. PASPascal. Source code; Like .

A typical Delphi GUI program is a set of units (*. PAS) which contain source. DPR file), while the forms (windows) are. DFM extension, ie. DPR = PAS + DFM. Here's a skeleton of a unit: //Name of the unit, which can then be referenced in other source files. Unit. 1. //List of public stuff, eg. You'll have to use Win. Message. Box(). instead: if Message. Box(Handle,'text','caption',MB. To enable this, just add the following line. Project's DPR file (via Project > View Source): begin. Report. Memory. Leaks. On. Shutdown : =true. Application. Initialize. Here's an example to trigger an error: procedure TForm. Button. 1Click(Sender: TObject). My. SL : TString. List. My. SL : = TString. List. Create. Reading from a text file. Here, we'll read the file line by line: procedure TForm. Button. 1Click(Sender: TObject). File : Text. File. Assign. File(my. File, 'C: \test. Reset(my. File). while not Eof(my. File) do. Read. LN(my. File,bit). text : = text + bit + #1. Show. Message(text). Close. File(my. File). A faster way: function Load. File(const File. Name: TFile. Name): string. with TFile. Stream. Create(File.

Extract. File. Dir() in a Data. Module? Application is declared in the forms unit. Here are some examples: var. TString. List. i : Integer. TString. List. Create. Add('unix=good'). Status = ' + Int. To. Str(Ping. 1. Reply. Status). Here's how to do it using Indy 9 (? The one that ships with Delphi 7): Moved to Internet Development with Indy components. Checking the class of an object. If you need to display the class of an object: Show. Message(My. Obj. Class. Name). Casting an object. Sometimes, it's necessary to help Delphi by casting an object: //Otherwise, E2. Incompatible types: 'TMemory. Stream' and 'TStream'. Perl. Reg. Ex. 1. Subject : = Stream. To. Text(TMemory. Stream(Rcvd. Stream)). Playing with date and time. Here's how to time tasks: var. Start.

In contrast, to make an independent copy of a dynamic array. Copy function. For. Check. Strings(A: array of string): Boolean. This indicates that the function operates on all arrays of the specified. See Open array parameters. Instead, you must either create a type.. TDigits = array. Open array parameters allow arrays of different sizes. Add(A: array of Integer). Note: open arrays are always zero- based., regardless of which. Low() you chose to declare the array.
