What do you want your program to do?
What are the tasks required to do this?
Which task(s) are you having trouble with?

Is it possible for a process to retrieve a Primary Token for whichever user account it is running under?
Can I then pass a handle of the token to an admin process, which would allow that admin process to use CreateProcessAsUser to create new processes in the context of the original user account?
Background:
I have a program that launches an updater program which requires admin privileges. After it performs the update, I need the updater to re-launch the main application, but under the regular user account, not the admin account.
This is Vista.

Why can't the main application be run from the admin updater program? It would run under admin privileges.. But does this matter?

Thanks for your reply. Unfortunately, it actually does matter which account it runs under, because a lot of application config is user account-specific, so the app must be run under the account of the person who wants to use it.

You could do something like create a small "in-between" program, running at user level, which runs the program set at admin level, and then runs the user-level app again? Or something similar to this?
Also, I'm sure that there is an API for elevation of an application.. So you create your admin-level application running as a user then elevate it to admin level?
Also, does this admin app have to run the user level app again? Can't you just hide the main window whilst the admin application is running, and get the admin level app to show it after it has finished?
I hate Vista too

Yes, your "in-between" idea might work. Thanks very much.
I wouldn't be able to keep the user-level app running while the admin app is doing its thing, because the admin app is an updater whose job is to replace application binaries with new versions!
So your in-between program idea might work as long as the in-between program itself never needs updating......
But I will seriously consider your idea if I can't find anything more direct.
Thanks very much!

Ah I see why my other idea wouldn't work. Sorry I was unclear.
And you're welcome I hope this method works

BOOL SomeFunc( LPSTR* arString )
{
//
return TRUE ;
}
void main()
{
//declare ??
BOOL bRet = SumFunc(??) ;
//HOW can i declare the varible for passing argument to LPSTR* arString and how to pass this to SomeFunc
}
//is there any other way to retrieve array of string from a function , is the method used above is correct for for this purpose ?
//thanks

LPSTR strA;
LPSTR strB[ 100 ];
<br />
SomeFunc( &strA );
SomeFunc( strB );
When passing arrays around, it is wise to also pass the number of members. To make life easier just use std::vector.
std::vector< LPSTR > vStr;<br />
<br />
BOOL SomeFunc( std::vector< LPSTR >& vStrings );<br />

He's not asking to pass arrays around, he asking how to pass a pointer to a pointer into a function.
Kinda like here's pointer, allocate something for me then modify my pointer to point to it.

Well, maybe your right. I got caught up in the LPSTR* thing but now that I reread it, your probably right.
My bad

<blockquote class="FQ"><div class="FQA">nitinmx wrote:</div>BOOL SomeFunc( LPSTR* arString )</blockquote>
LPSTR* is a pointer to a pointer. I am assuming you want the function to allocate some memory and modify your pointer to point to it. If this is what your after, here's a sample...
int CTestPPView::SomeFunc(LPSTR* pPointer)
{
ASSERT(pPointer);
ASSERT(*pPointer==NULL);
char* pString="This is a test";
int nLength=strlen(pString)+1; // Add one for null terminator
// Modify the passed in pointer to point to allocation
*pPointer=new char[nLength];
if (*pPointer) {
strncpy(*pPointer,pString,nLength); // Copy some string to it
return nLength;
}
return -1; // Error
}
// In some method elsewhere...
LPSTR lpString=NULL;
int nLength=SomeFunc(&lpString);
if (lpString) {
TRACE("%s\n",lpString); // Just to display in debug
delete[] lpString;
}

UPDATE: Now that I reread your post, I realize LPSTR* is not correct for what you are apparently trying to do. Waldermort appears to have interpreted correctly what you are asking for so just ignore my post.

Hello Friends i am using Win32 Application. And i want my dialog box to have some color on it rather than same old boring color..
can anybody plz tell me how to colour the dialog box and put pictures on it.
|
|
|
|
|
you can set the window color when u Registering Window class, or by using SetClassLong function.
SetClassLong( hWnd , GCL_HBRBACKGROUND , (LONG)hBrush) ;
handle WM_CTLCOLORDLG if u have a dialog application.
u can use CreatePatternBrush to paint picture.

When a DLL is loaded, is there a way to determine what loaded it; the application or another DLL?
In other words, say application APP loads DLL_1. DLL_2 get loaded. Can DLL_2 determine whether it was loaded by APP or DLL_1?

Unfortunately not since that's not what I asked, but thank you anyway. I have a DLL that needs to know at runtime what loaded it.

I believe that if you call GetModuleFileName(), it will return the file name for the parent process, if it is an executable file; read up on it on MSDN.
As written by MSDN for the hModule parameter, "If this parameter is NULL, GetModuleFileName retrieves the path of the executable file of the current process"
Hope this helps!

Not to be too rude, but I know that. I was EXTREMELY clear that I needed to know what executable loaded my DLL, not what process. In other words, an application may load a DLL, which in turn may load my DLL. I need to know what loaded my DLL at runtime. (There may be several executables between the main application and my DLL.

OK I was just trying to help.. You know I read somewhere on the Internet that there are some data structures out there which are stored and set when DLL's are loaded which has all information about the DLL, such as reference count. Maybe there is a variable which has whether the DLL was loaded by an EXE or DLL. You'll have to find this yourself though as I'm not doing your research.

And in this case, GetModuleFileName(NULL, ...) would return the name of the EXE whose address space contains your DLL, regardless of how many other EXEs were loaded first. For example:
A.EXE --> CreateProcess() --> B.EXE --> CreateProcess() --> C.EXE --> implicit/explicit linking --> YOUR.DLL
In this scenario, GetModuleFileName(NULL, ...) would return C.EXE.
