My program written in bcb looses its style after its being injected to the process. I was expecting it to look like the exe on the picture.
How can the dll style be fixed/forced to be same as normally on win 7, or on any other windows its being ran on?

You could make a loader/injector that has your dll and a manifest file embedded into itself. Before it extracts and injects the dll into the selected process, it'll extract the manifest into the process' file directory.

Ah so the manifest is the answer.
Thanks for the tip, il start with this and see if i get it to work.

Edit: Somehow i cant seem to get anykind of manifest to work and to solve the problem. Has anyone done this for Borland C++ Builder before?

I have not tested it with Borland C++ Builder, but this works in VC++. Put this at the top of your .cpp file (taken from MSDN):
Code:
#pragma comment(linker,"\"/manifestdependency:type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='*' publicKeyToken='6595b64144ccf1df' language='*'\"").

Probably cuz there is a dot in the end... dunno how it got there. Anyways this is taken from one of my dll source, it should work for you too.
Code:
#include <commctrl.h>

#pragma comment(lib, "comctl32.lib")
#pragma comment(linker, "/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='*' publicKeyToken='6595b64144ccf1df' language='*'\"")

Still the same warning message and nothing on the gui changes.
I already tried to force in the XP manifest file with winlicense, and nothing changed.
It seems that bcb doesnt support value "linker"

#pragma comment

Syntax

#pragma comment (comment type, "string")
Description

The comment directive lets you write a comment record into an output file. The comment type can be one of the following values:

Value Explanation

exestr
The linker writes string into an .obj file. Your specified string is placed in the executable file. Such a string is never loaded into memory but can be found in the executable file by use of a suitable file search utility.

lib
Writes a comment record into an .obj file. A library module that is not specified in the linker's response-file can be specified by the comment LIB directive. The linker includes the library module name specified in string as the last library. Multiple modules can be named and linked in the order in which they are named.

user
The compiler writes string into the .obj file. The linker ignores the specified string.

Edit: Now that i checked the DLL with PE explorer, it seems to have a manifest like this inside it, still the style issue is same...

Code:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
  <assemblyIdentity
   type="win32"
   name="DelphiApplication"
   version="1.0.0.0"
   processorArchitecture="*"/>
  <dependency>
   <dependentAssembly>
     <assemblyIdentity
      type="win32"
      name="Microsoft.Windows.Common-Controls"
      version="6.0.0.0"
      publicKeyToken="6595b64144ccf1df"
      language="*"
      processorArchitecture="*"/>
   </dependentAssembly>
  </dependency>
  <trustInfo xmlns="urn:schemas-microsoft-com:asm.v3">
   <security>
     <requestedPrivileges>
      <requestedExecutionLevel
        level="asInvoker"
        uiAccess="false"/>
     </requestedPrivileges>
   </security>
  </trustInfo>
</assembly>

place a separate application.manifest file in the folder of the application you inject the dll to

The application itself probably doesn't have styles enabled

That seems to be the answer, i injected the dll into another process which triggered the style to pop up correctly.

Thanks for the replies, another problem solved.
