【问题描述】:
我正在开发 PDF 下载器和库,当我为我的项目制作安装程序并成功完成它时。 但是,当我想使用二进制数据打开存储在 SQL Server 中的 pdf 文件时,会出现以下错误:
这一行是 328
Dim fs As New FileStream(filename, FileMode.OpenOrCreate, FileAccess.Write)
您的应用程序中发生了未处理的异常。如果你点击 继续,应用程序将忽略此错误并尝试 继续。如果单击退出,应用程序将立即关闭。
对路径 XXX 的访问被拒绝。

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
For example:
<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>
When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
【问题讨论】:
-
异常文本的第一行告诉你一切。你在 pdflib\pdflib\libhome.vb:line 328 行做什么?
-
访问被拒绝。看来这条信息很清楚。
-
我单击按钮从 sql server 打开 pdf 我已将此行添加到我的问题中,但项目在路径 pdflib\pdflib\bin\Debug\PDF Library.exe 中工作正常
-
它与 SQL Server 无关,它是你在不同的目录中运行它,现在它已经存在并且你没有写入所需的权限。您通常不会在程序文件夹中写入临时文件或其他文件,其中有应用程序数据文件夹。
