erro com gravação no registro do windows na versão vista

Alex Mauricio · Janeiro 13, 2010

Boa noite pessoal. Como é comum, estou novamente com meus probleminhas.

Tenho uma aplicação pronta e que está funcionando corretamente. Porém, na empresa que utilizo, vai migrar todas as estações de trabalho para Windows Vista ou 7 (não está certo qual das 2 versões ainda).

Porém, eu me antecipei e fiz um teste e tive a desagradável surpresa que é o seguinte:

Toda vez que eu rodo a minha aplicação pela primeira vez, o sistema verifica se existe uma chave no registro e caso não abre um formulário de configuração.

Esse formulário deveria criar uma chave no registro do windows e salvar um valor.

Antes funcionava, agora quando mando gravar, não apresenta nenhum erro, porém não cria a chave e muito menos salva o valor. Segue o código abaixo referente ao botão GRAVAR CONFIGURAÇÕES e o código que está em um módulo. ( O CÓDIGO SUBLINHADO SÃO AS LINHAS QUE FAZ A GRAVAÇÃO NO REGISTRO).

Boa noite pessoal.

Tenho uma aplicação e estou fazendo algumas modificações... no micro que estou desenvolvendo está funcionando perfeitamente, porém, em outros micros com o mesmo sistema operacional (windows xp) não está funcionando tão bem assim.

O erro é o seguinte, quando vou abrir a Aplicação aparece a seguinte mensagem...

"Compile Error:

Can't find project or library"

Caso de OK, ele aponta erro na função GetKeyValue e seleciona a String$ ( conforme selecionado em negrito).

Porque em uma máquina funciona e em outra não? (segue o código em anexo e esse código está em um módulo)

Obrigado
