Recently I needed to convert a C header file to Delphi which contained bitfields. Let’s take a look at a sample structure that contains bitfields: typedef struct _BITFIELDSTRUCTURE {     DWORD dwValue1;     ULONG BitValue1: 1;     ULONG BitValue2: 1;     ULONG BitValue3: 1;     ULONG BitValue4: 1; } BITFIELDSTRUCTURE, [...]

“Have you ever seen the rain (on your background image through a Delphi window)?” Ok, sorry to all the Creedence Clearwater Revival fans out there . Today we wanna talk about how to achieve translucent Delphi windows with Windows Vista. I know this does not sound like a big deal for all the lucky owners [...]

I hope you enjoyed the first part of the introduction to BITS. In this second part, we want to improve our job list (a little bit) and start own dowloads. The first task is, to replace the old TListbox with a TListview. I switched the ViewStyle to vsReport and added 3 columns: Name, State, GUID. [...]

Dear Visitor/Delphi programmer, As the main developer of JWSCL and the author of the most blog posts here, I will retreat from the projects for the next months. At least I will try to fix bugs, write some articles and manage the whole project as a project manager. Don’t expect much from me the next [...]

The JEDI API Library project (JWA) has been successfully revived from a sleep status to an active project with lots of ambitions. Some recent achievements are the new include model of JWA, the release of JWSCL (the Security Library) and of course the “birth” of this blog.

Nobody uses them so they weren’t corrected. At the moment I prepare Rudy Velthuis’ API headers for JEDI API integration. By accident I found some functions which are only available as UNICODE version. However they were also declared as ANSI !? To make it quick, it wasn’t Rudy’s mistake but Microsoft’s. The following functions are [...]

As you may know code is shared among JEDI projects and so is part of the code that I am going to describe in this post. A few years ago I got involved in the JCL project and contributed code that I had written quite a while before. One of the things I always found [...]

CreateProcess is a little tricky to use. Thus I write the full example code here so you don’t have to worry. uses SysUtils, JwaWindows, JwsclStrings; procedure StartApp(const App, Parameters, CurDir : TJwString); var   StartupInfo: {$IFDEF UNICODE}TStartupInfoW{$ELSE}TStartupInfoA{$ENDIF};   ProcInfo : TProcessInformation;   pEnv : Pointer;   pCurDir,   pCmdLine : TJwPChar; begin   ZeroMemory(@StartupInfo, sizeof(StartupInfo)); [...]
