First - so I don't get in any trouble - I've posted a similar question on other forums but have not gotten any responses so branching out in my quest for help as well as changing the question a little.

Previously I was trying to find out why calling LoadUserProfile(...) was not creating the User Profile if it did not already exist (for example when creating an account programmatically) - MSDN had the following article on HOW TO but it doesn't seem to work (copy/paste the code and switched it to C# - account is created, no failures or exceptions, but User Profile is just not created)
http://support.microsoft.com/kb/196070/en-us

Now, forget this as I assume it just isn't the right approach (or just doesn't work anymore - hopefully not me making a stupid mistake)

Anyways - my question is - what other means can I use to programmatically create a USER PROFILE for a user account?
Is there some kind of CreateUserProfile(...) function (I couldn't find one on MSDN), etc...

Any help would be much appreciated...
Thanks,

Sadly not that I can see - this is all about creating and managing the accounts and does not touch on the User Profiles themselves.
But thanks - good source of information.

I'm not sure you can invoke the creation of the new user's profile without logging the user onto the system, which is when a new user's profile gets created (logging in for the first time).

Have you tried LogonUser (advapi32.dll) and Impersonation? See: Windows Impersonation. I have my doubts, but if you have not tried it yet you might give it shot.

Sadly yes I have tried both and neither create the profile (impersonation itself doesn't create a user profile, nor does LogonUser) - actually the only place I have ever seen mention that you can is in that MSDN article but it doesn't seem to work on my system (copy/paste the sample code).

Thanks,

What OS are you testing that LoadUserProfile call on?

I have tested with both Windows 2000 pro and Windows XP SP2

OK, I ran this code on my XP laptop and it did create the profile. However, when I went to look under documents and settings, the username I expected to see was cryptic looking (3 vertical rect chars?)--I don't know what you call those chars but you see them all the time if you open a binary file in notepad.

Anyway, take a look at it and let me know also if it worked and what's up with how it created my user's folder name as mentioned above. It is initiated by calling static method: WindowsLoadUserProfile.Test()

Wow - that fixed my first problem all right - I wasn't setting up LogonUser properly (forgot to convert to (int) some of the ENUM parameters).

Now the Profile is created but just like you said I get the odd squares (invalid windows characters) - not sure why but it is a problem as Windows actually re-creates a correct one when logged-on.

So close - if you figure it out let me know - I'll be working on it also at this end and if I find the reason I'll post back.

Thanks a lot ...

That should create the profiles properly

That fixed the immediate problem of having to set the name without the illegal characters (great) - but it seems to have introduced something else.

The account is created fine, as is the user profile - but now subsequent calls to LogonUser(string, string, intptr, ...) fail with invalid username & pasword - do I need to do some funky Marshal/Unmarshal conversion to the username, domain, and password for it to work now that LogonUser has changed?

If I remove all the Marshalling added LogonUser works fine ...

DdoubleD: why do you only set the Password to IntPtr and do the Marshling? Why not username and domain also?

Because of this prototype declaration I found (see below). It's possible that it is incorrect because I just pulled it off the web and not from MSDN, which we know is always correct too--LOL.

Anyway, after really thinking about it, I doubt seriously that prototype is correct using "String" in a Win32 API call. Also, look at the variable naming convention: lpsz, or long pointer to null-terminated string (long pointer to null terminated char array in C/CPP; aka char*).

The answer is near though...

/// 
        /// The LogonUser function attempts to log a user on to the local computer.
        /// 
        [DllImport("advapi32.dll", CharSet = CharSet.Auto, SetLastError = true)]
        private static extern bool LogonUser(String lpszUsername, String lpszDomain, IntPtr lpszPassword, int dwLogonType, int dwLogonProvider, out IntPtr hToken);

From what I can see LogonUser takes an LP**T**STR, not an LPSTR, as parameters. You should just use the default string marshaling, and it will work correctly. See LogonUser and pinvoke.net's declaration for a property P/Invoke of LogonUser.

But this causes the odd unrecoginized square characters when creating the profile (LoadUserProfile) ... lol ... no way to win? :)

Ooooooh Scott, come on man, I know you know the answer... ;) Help us out please?

Well - wasn't able to figure out why but there is a difference between NETWORK and INTERACTIVE logon type, if you use INTERACTIVE and do not include any of the marshaling then everything works perfectly fine - and that is what I needed ...

You have both provided me with a LOT of help - thank you very much ... Let me know if you figure out why it is different when using the NETWORK login type.

Not sure why it is different, but I can tell you why I used NETWORK. The MS link indicated it was best:

// Do a network logon because most systems do not grant new users
      // the right to logon interactively (SE_INTERACTIVE_LOGON_NAME)
      // but they do grant the right to do a network logon
      // (SE_NETWORK_LOGON_NAME). A network logon has the added advantage
      // of being quicker.

Did you get it working?

I have a hunch that there is a problem with that. After I ran that code I started noticing odd behavior on my machine. I closed winamp and when I re-opened it all of a sudden my playlist was different.

Then I started noticing websites where I have my password stored, like daniweb, required me to log in again. I was thinking 'wtf'

Then I tried to reboot my machine:

The attempt to rebootSCOTTIE failed

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.
The attempt to power off SCOTTIE failed

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

That being said it I think that code screws up who windows think the logged on user is. The *only* thing that worked was logging off which then finally allowed me to reboot and since then everything has seemed ok. Review the code for something changing the active user. If you can't find anything then let me know and I will take a look at it.

Its a very long piece of code and i'm in the middle of a project right now :(

[edit]
The NETWORK vs. INTERACTIVE might have been the issue. It might have switched the INTERACTIVE logged on profile (me) to that user profile that I created. I deleted the profile directory in C:\Document and Settings\ right after I created it, which may be why the browser cookies etc couldn't save.

LOL - My sympathies too. I didn't have any trouble except for what I initially reported, but I only ran the code once that I submitted and none of the proposed changes. Several hours later I simply shutdown all my apps, deleted the new user, rebooted, then deleted the document folder.

:D ...still laughing...

I would like to suggest keeping this thread alive until all of the "minor" issues, :D, have been resolved, then posting a final solution so others can benefit.;)

Yeah ... I hope whoever ventures across this thread reads all the way to the end too :)

Article pretty usefull, it was exactly what I was looking for... I had an idea how to create a user profile, but this clarified some of my doubts

I ran above code but LogonUser() returning with false.what would be the problem?

commented: Windows changed over the years. You may have to research new ways and create new code. Also, why not a batch file? +15
