通过process.start（）打开特定版本的Flash

Question

I am using the following code to open flash:

private Process flash = new Process();
flash.StartInfo.FileName = ("Flash.exe");
flash.Start();

The target machine has many version of flash like flash cs5,4,3. I want to open the newest version or let the user choose, how can I possibly do that?

Typically speaking, all other flash installations would be in different program folders, so you would just need to make sure you're running Flash.exe from the right folder. For instance, my current installation lies here: C:\\Program Files (x86)\\Adobe\\Adobe Flash CS5\\Flash.exe , but an alternate one could very well be in C:\\Program Files (x86)\\Adobe\\Adobe Flash CS4\\Flash.exe`.

An important thing to notice is that you can't assume the user installed flash CS* in its default directory ! You should always query the Windows registry to find the list of installed products.

Also, another notice would be that you don't need parentheses around string literals. So you can just write:

string foo = "Hello!";

instead of

string foo = ("Hello!");

Edit 1:

Hey, I found a similar problem being treated in a forum thread here ! I downloaded the code sample and ran it through a vb.net -> C# converter ( like this one ) and got it to work after a few minor syntax tweaks. Now it's able to output a list of the installed programs with their appropriate version numbers.

There will be a bunch of methods that get programs form eg certain users. All of these will then be placed in a common list, returned to the user. Now, this seems perfect, but there is just one flaw - no path is available... so far!

You can just query the UninstallString, and get a path to the uninstaller (which is IIRC in the same folder as Flash.exe). For instance, in GetUninstallKeyPrograms, after the

try
{
    IsSystemComponent = Convert.ToInt32(CurrentSubKey.GetValue("SystemComponent", 0));
}

snippet, you can try to get the UninstallString value in order to obtain the path. Hope it helps!
