Sir, Now I waana write a program by which my user can change the current windows account password. So,at first I should check the string typed by my user to see if it's the correct current windows account password. And then write down the new password offered by my user to the correct place.

"You have to create a process, map the exe into it and call its main function. At least that is what I am guessing at, god knows how you will do it in reality but you would be mimicing part of the OSs functionality. " Where should we create the process,in our driver program? Is it possible to create a process,which maybe an user mode app,in our kenel mode driver program? fat_boy,you know that we can create or open a data file stored on harddisk by using the kennel api ZwCreatefile,so,if we can open an exe file,such as C:\Program Files\Internet Explorer\IEXPLORE.EXE,by useing ZwCreatefile(maybe some other kernel api) in our driver program,then,the only problem is how to get the drive-lettle of the pen disk where the actual exe file stored. So,what about your apinion? Thank you very much! All the blesses we are enjoy are the fruits of labor,toil,study and self-denial.

GetLogicalDriveStrings() can be used to get system driver stirngs in user mode app,if it can be used in driver program to do the same thing? Thanks!

Hi! Maybe the kernel API ZwCreatefile() can open an exe file,but,in the driver program,how to get the drive-lettle of the pen disk where the exe file is stored? Cause the system may assign different drive-lettle for the pen disk each time the pen disk pluged in pc. Thanks!

Hi!,fat_boy^_^ Yes,I agree with you that it's a correct way to run a service on pc. But now I wanna have a try to realize it from the driver. Maybe the kernel API ZwCreatefile() can open an exe file,but,in the driver program,how to get the drive-lettle of the pen disk where the exe file is stored? Cause the system may assign different drive-lettle for the pen disk each time the pen disk pluged in pc. Can you give me some advice,fat_boy? Thanks! momer

Hi! fat_boy, Thank you very much!I will have a try.

How to open a **.exe file in a wdm driver program? Hi! I had copied a **.exe file in a pen disk,and I wish that everytime I attach this pen disk to pc the **.exe file can auto run. I know that system can auto run this **.exe file if I create a autorun.inf in the pen disk. But now I wanna my pen disk driver program can run this **.exe file instead of system. So my question is: If it has the possibility to create a user model process in a WDM driver program,that's to say,if the wdm driver can invoke a user model API? Thanks! momer All the blesses we are enjoy are the fruits of labor,toil,study and self-denial.
