Nos dados reais, tudo funciona.

#property tester_library "Kernel32.dll"
Isso parece ter ajudado.
 
Juer:
Isso pareceu ajudar

Não, não ajudou.

  
#property tester_library "wininet.dll"
#property tester_library "Kernel32.dll"
Muito bom... O teste funciona após a compilação. Ao depurar no modo de teste, ele não funciona. E depois não funciona durante o teste.

Muito bom... O teste funciona após a compilação. Ao depurar no modo de teste, ele não funciona. E, depois, não funciona apenas durante o teste.

Após a execução no modo de depuração, o arquivo ex permanece nesse modo. Aparentemente, somente a versão de lançamento funcionará.

 

De qualquer forma, obrigado pela excelente biblioteca.
Finalmente consegui fazer o POST de dados por meio do wininet, portanto, deixe-me também contribuir com algo aqui:

para violação de acesso,
1. Alterar "nill" para NULL não ajuda
2. Alterar "nill" para 0 não ajuda

O que eu fiz foi alterar o seguinte:

--- string nill = "";
+++ string nill = "\0";

e tudo ficará bem depois disso. Aproveite :)
