错误“方法”〜对象“〜”的失败”编译时 [英] Error "Method "~" of object "~" failed" While compiling

问题描述

我正在尝试更新已将IP硬编码到DB连接字符串中的旧版应用程序，它的对象〜的方法〜失败错误。我们不确定为什么会收到此错误，我们可以获取VB6可以为我们提供更多详细信息，或者我们可以在已编译的EXE中更改数据库连接的IP。

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

另一个检查您可能要放弃的是为整个项目设置 Option Explicit 。这将向您显示尚未显式声明的变量。

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，您可能希望调查所有 Object ：后期绑定可能是意外的痛苦，我建议尽量减少后期绑定。

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.

然后是COM。如果应用程序已针对其他版本的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，则方法可能已被删除或重命名。

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/更好的错误处理程序，以便您确切地知道哪一行代码会产生错误。

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

编辑如果您没有源代码，则剩下的唯一选择就是找出已对应用程序进行了测试的MDAC /数据库组件版本。

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.
