VB6编译时出错 [英] VB6 Error While compile

问题描述

我试图更新一个遗留的应用程序，其中的IP硬编码到DB连接字符串，它的错误与方法〜对象〜失败我们不知道为什么我们得到这个错误，我们可以

I am trying to update a legacy application which has the IP hardcoded into the DB connect string, It errors with "Method "~" of object "~" failed" We are not sure why we are getting this error, can we get VB6 to give us more detail or can we change the IP of a DB connect in an compiled EXE.

推荐答案

另一个检查你是否可以在一个编译的EXE中更改一个DB连接的IP。可能想要放弃的是为整个项目设置选项显式。

Another check you might want to give a go is setting Option Explicit on for the entire project. This will show you the variables that have not been explicitly declared.

此外，您可能需要调查 Object ：晚绑定可能是一个非预期的疼痛，我建议尽可能少的晚绑定。

Also you might want to investigate all variables of type Object: Late Binding can be an unintended pain and I suggest to have as little Late Binding as possible.

然后有COM。如果应用程序已针对不同版本的COM组件（如OLEDB / ADO MDAC组件）进行编译和测试，并且现在针对新版本运行，则可能已删除或重命名了方法。

Then there is COM. If the application has been compiled and tested against a different version of a COM component such as the OLEDB/ADO MDAC components and now is running against new versions, methods might have been removed or renamed.

最后，尝试添加更多/更好的错误处理，以便确切知道哪行代码会生成错误。

Finally, try to add more/better error handling so you know exactly what line of code generates the error.

EDIT 如果没有源代码，剩下的唯一选项是找出应用程序已经过测试的MDAC / Database组件的版本。

EDIT If you do not have the source code, the only option left is to findout against what versions of MDAC/Database components the application has been tested.
