you can try to access the windows register at

and catch the value of Logon User Name key.
Your Approch is right,but from the service this approach is wrong.if you try to open HKEY_CURRENT_USER from service instead of opening of that it open HKEY_USER/.Default. you can try. because sevices start before logon,on logon OS decide which is current user whihc registry setting he is going to use.
now question arise how to open the current user from service
solution is right there HKEY_USERS\{Current Logon USER SID}\is TRUE replica for HKEY_CURRENT_USER

I assume you know that a service can make no assumptions about whether a user is logged in or not.

Hi all,
I am sorry if this is a stupid question.
I would like to write a application using vc++.
Can I do some thing in my application which restricts the user to install or uninstall any application/ software from the system . I know about failing a write or create operation . But that I guess will be a disaster.
So could it be some thing like we have some process or thread which is only used for installations and uninstallations- and I fail that.
Any ideas ??
Thanks in advance.

Hello,
I am working with MDI application in VC++. My view is derived from CFormview. I have many controls on the form view. When I resize the form view, all my controls should be resized and this should work for different screen resolutions.
Can anyone please help me in doing this. Thanks in anticipation of information.

To test different cardreaders,I wrote a program to do the write/read data test.At first,copy a file of certain size form Harddisk to the cards,and then read the file form every card(s) and campare the data with the source file data.According to the capacity of each
card,I should choose comparative file size from a ComboBox,such as 1MB,32MB,64MB,512MB,1GB,ect.Amd what's more,I can not know what the number my user will input to the ComboBox.So,my question is:If there is a way to let me read 1GB(or some other number>1MB) data from a file(size more small and more better.)?
Thanks!

Yes, but it's doubtful you can do it all at once (the memory manager is not going to be able to allocate that much contiguous RAM). I would recommend reading it 1MB at a time.
I've not tried it, but I think you can quickly create a file of size N by calling SetFilePointer(..., N, NULL, FILE_END) followed by SetEndOfFile().

Use GetSelItems().

Are you referring to associating file types with a program?
This link might help:

it doesn't talk about context help menu of Windows explorer.

One of the sections is on extending shortcut menus.

Michael Dunn has written some excellent articles here on CodeProject about this topic - trying looking for his articles.
What you require is a 'shell extension'.

Andrew,
thanks.
i did read part of his articles (1-9) before - all are in COM.
i really don't like COM.
i think there must be simple way to do that - may be we just need to modify register, similar to doing for double-clicking a file.
cheers

Which file type's context menu are you interested in modifying?

when we right click a file in Explorer, the munu pops up.
we can see WinZip or "Send to" folder on it.
file extension can be any, i.e. .mytype or .class

There is no single way to do this. If you are wanting to add to a context menu that already exists (e.g., the one that pops up when you right-click a .dll or .cda file), you have one set of steps. For example, if you wanted to add to the context menu of a .dll file, you could save the following to a .reg file and merge it into the registry:
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\dllfile\shell\Calc]
[HKEY_CLASSES_ROOT\dllfile\shell\Calc\command]
@="c:\\winnt\\system32\\calc.exe" If you are wanting to create a new context menu for an extension not yet registered (e.g., .mytype), you have a different set of steps.
