Using Relative Path with Registry Key

[tpra21]

I have a difficult question that I cannot find any information on. Say I want to get the current username value from the registry using the following code:

[SIZE=2][/SIZE][SIZE=2][COLOR=#0000ff]Dim[/COLOR][/SIZE][SIZE=2] userRegKey [/SIZE][SIZE=2][COLOR=#0000ff]As[/COLOR][/SIZE][SIZE=2] RegistryKey = Registry.CurrentUser
userRegKey = userRegKey.OpenSubKey([/SIZE][SIZE=2][COLOR=#800000]"Software\\Microsoft\\Active Setup\\Installed Components\\{44BBA840-CC51-11CF-AAFA-00AA00B6015C}"[/COLOR][/SIZE][SIZE=2])
[/SIZE][SIZE=2][COLOR=#0000ff]Dim[/COLOR][/SIZE][SIZE=2] value1 [/SIZE][SIZE=2][COLOR=#0000ff]As[/COLOR][/SIZE][SIZE=2] [/SIZE][SIZE=2][COLOR=#0000ff]Object[/COLOR][/SIZE][SIZE=2] = userRegKey.GetValue([/SIZE][SIZE=2][COLOR=#800000]"Username"[/COLOR][/SIZE][SIZE=2])
[/SIZE]

Now, how can I get the Username key value if I don't know the directory (Folder) names of the folders in the path. For example, if I don't know the name of the "Active Setup" folder in the path above, can I use the above path and plug a variable in.

Or, is there a function that can get me the registry key's path by using the key's (subkey's) name like "Username."

Thanks in advance, Adam

Not sure what you ask, but here's a few tries:

If you get partial path information from elsewhere you can add the strings up to the full path:
dim fullpath as string = "partpath" & pathinfovariable & "morepath"

If you want to employ different search methods you can use the RegistryKey methods GetSubKeyNames and GetValueNames

Each of what called "folder" in the path given is a RegistryKey if you didn't know.

The problem I have is a PDA is plugged into the PC. The PDA installs a documents folder on the PC. In the registry, it creates a path consisting of three folders and with registry key in the third folder. Example:

Registry key path:

Software\Windows CE\56af443d\

Then we have a registry key called "Briefcase Path" stored at the end of the above path. If I plug this PDA into a different PC, it creates the same path above, but the numeric directory (56af443d) changes to a different number. I need a way to programatically grab that directory name and store it in a variable, which I will then store in the file path declaration.

That way, everytime a user installs my software on a different PC and uses a different PDA (there are eight total that this company uses) to plug into it, the file path will not bomb.

Hope this is more clear.

Thanks, Adam

Unless the (56af443d) have a special meaning and you can get from anywhere you have to search. Using the RegistryKey.GetSubKeyNames method first on Software\Windows CE\ then on each of those key names returned to find "Briefcase Path".

Possibly, this can help getting the path directly http://66.129.67.100/247reference/msgs/28/140245.aspx (see the paths used in last post) or this http://www.pcreview.co.uk/forums/thread-1299478.php

Thanks for the post. That code worked!

Thanks again, Adam
