Question

我想将每个文本框中的字符数限制为4位。

它可以在C＃Winform中实现，但是不熟悉如何在NSIS中使用它。

尝试的操作：

我贴上标签，然后将输入引导至四位数。

但这不好。

我试图通过NSIS论坛查找信息，但是找不到。

附加文本框图像：

NSIS代码：

import org.springframework.cloud.contract.verifier.messaging.MessageVerifier;
import org.springframework.context.ApplicationContext;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.support.converter.MessagingMessageConverter;
import org.springframework.messaging.Message;
import javax.jms.JMSException;
import java.util.Map;
import java.util.concurrent.TimeUnit;

public class ActiveMqStubMessages implements MessageVerifier<Message<?>> {
    private final ApplicationContext applicationContext;

    public ActiveMqStubMessages(ApplicationContext applicationContext) {
        this.applicationContext = applicationContext;
    }

    @Override
    public void send(Message message, String destination) {
        throw new UnsupportedOperationException();
    }

    @Override
    public <T> void send(T payload, Map<String, Object> headers, String destination) {
        throw new UnsupportedOperationException();
    }

    @Override
    public Message<?> receive(String destination, long timeout, TimeUnit timeUnit) {
        final JmsTemplate jmsTemplate = applicationContext.getBean(JmsTemplate.class);
        final long originalReceiveTimeout = jmsTemplate.getReceiveTimeout();
        try {
            jmsTemplate.setReceiveTimeout(TimeUnit.MILLISECONDS.convert(timeout, timeUnit));
            return (Message) new MessagingMessageConverter().fromMessage(jmsTemplate.receive(destination));
        } catch (JMSException e) {
            throw new RuntimeException(e);
        } finally {
            jmsTemplate.setReceiveTimeout(originalReceiveTimeout);
        }
    }

    @Override
    public Message<?> receive(String destination) {
        return receive(destination, 3, TimeUnit.SECONDS);
    }
}

NSIS INI文件：

Function Test
  !insertmacro MUI_INSTALLOPTIONS_READ $0 "pageInputLicenseInfo.ini" "Settings" "State"
  ${If} $0 == 9 # btton 
    !insertmacro MUI_INSTALLOPTIONS_READ $R0 "pageInputLicenseInfo.ini" "Field 1" "State"
    !insertmacro MUI_INSTALLOPTIONS_READ $R1 "pageInputLicenseInfo.ini" "Field 2" "State"
    !insertmacro MUI_INSTALLOPTIONS_READ $R2 "pageInputLicenseInfo.ini" "Field 3" "State"
    !insertmacro MUI_INSTALLOPTIONS_READ $R3 "pageInputLicenseInfo.ini" "Field 4" "State"
    !insertmacro MUI_INSTALLOPTIONS_READ $R4 "pageInputLicenseInfo.ini" "Field 5" "State"
    !insertmacro MUI_INSTALLOPTIONS_READ $R5 "pageInputLicenseInfo.ini" "Field 6" "State"

    nsExec::ExecToStack '$INSTDIR\ParamterTestConsole.exe ${PRODUCT_NAME} $R0 $R1$R2$R3$R4$R5'

    Pop $2 ; Exit code
    Pop $3 ; console OUTPUT

    Blah blah..........

FunctionEnd

请帮助我。

Answer 1

如documentation中所述，您可以使用MaxLen选项。

示例：

[Field 1]
Type=Text
Text=1
Left=29
Right=275
Top=46
Bottom=57
MaxLen=4
