i am using this code to print pdf from a vb.net program as found on the googling. but when i run this code it shows "no program is associated with this process".Can any one help me with solution?

推荐答案

ProcessStartInfo("C:\Program Files\Adobe\Reader 11.0\Reader\AcroRd32.exe")

使用双引号使VB知道它们之间的字符串。它们工作正常。



当VB将该字符串传递给操作系统时，它会删除双引号（它们只适用于VB中的编程）。这使得字符串显示为由空格分隔的多个字符串： C：\Program ，然后 Files \Adobe\Reader 和 11.0\Reader\AcroRd32.exe 。这不是一个流程所期望的。



尝试这个

uses double quotes to make VB aware of a string between them. They are working fine.

When VB passes that string to the OS, it removes the double quotes (they are just for programming in VB anyway). That makes the string appear as several strings separated by spaces: C:\Program, then Files\Adobe\Reader and 11.0\Reader\AcroRd32.exe. That's not what a process expects to see.

Try this one

ProcessStartInfo("""C:\Program Files\Adobe\Reader 11.0\Reader\AcroRd32.exe""")

最左边的双引号仍然存在。但是在字符串中，有两个加倍的双引号，VB转换为两个双引号，当它传递给操作系统时保留在字符串中。

The outermost double quotes remain. But inside the string, there are two doubled double quotes, which VB translates into two double quotes that remain in the string when it's passed to the OS.
