Question

我将应用程序从vb6迁移到vb.net，除了从MQ服务器获取消息之外，每个事情都正常工作，当MQGet调用时，我得到2033错误（没有消息）
还附加了从工作vb6和不工作的vb.net发送到MQ的捕获消息，请帮忙吗？enter image description here

如果你得到2033，那么你知道队列在那里，但是你试图检索的消息不是。使用MQ Explorer或普通MQ样本以及runmqsc检查该队列上是否有任何消息，如果有，则其相关ID是否与您的程序提供的相匹配。

如果那里没有消息，那么请检查您发送给他们的CICS程序是否确实已收到您的消息，以及该程序是否已响应。

2033问题可能是您的编码问题，但更可能是配置和设置中的某些内容随着您的转换而发生了变化。您可能具有不同配置的队列管理器，具有不同配置的通道等。检查整个链。
