Select a drive only

[alibaba]

Hi,

I need a dialog where the customer can only select a drive. He should not select a path, because the install path is always <selected_drive>\Application .
How can I realize it with InstallAware? Anyone an idea, hint?

Thanks in advance

Dear Alibaba,

the first that comes to my mind is;

- Use the "GetLogicalDriveStrings" WINAPI to retrive a strings that specify valid drives in the system.
http://msdn.microsoft.com/it-it/library/windows/desktop/aa364975(v=vs.85).aspx
- Then fill a Combobox using a script varible that contains the driver list.

Hope this helps you.

Thank you Francesco, I did not know this function yet. I tried it but the string with the Drive list alsways contains only the "A:\" drive. I tried a lot, but always the same.

Thank you anyway!

Dear Alibaba,

Yes, I see what you mean.

This happens because the function returns a series of null-terminated strings, one for each valid drive in the system.

Unfortunately it is not possible to parse via IA script, each Null - Termination that delimits the returned drive string.

Alternatively, you could create a specialized DLL or EXE that calls the "GetLogicalDriveStrings" WINAPI and then to execute it from your script.
There are many examples available from the web on how to use the function.

Hope this helps you.

Thank you very much for your Test. I can now stop my tests and will try to create a DLL.

Best Regards!
