If you want to use Win encryption as simply as possible then use CryptProtectData()/CryptUnprotectData() to encrypt/decrypt the secret data before/after writing/reading the registry.
These will allow you to use either the machine key (any user on machine can decrypt the data), or the current user key (only that user can decrypt the data).

How do I go about getting a storable value from the encrypted DATA_BLOB that can be stored/recovered from the registry and re-inserted in a new DATA_BLOB struct for decryption later on? Thanks...

if you are putting the app into the public domain, then I suggest that you use at least des56. The hackers out there WILL try to break your encryption and if you use xor or bit flipping, they will break it and post the findings on a hundred hacker bulletin boards. MS has some simple envelope and password encrypt functions in their csp that make it easy or there are many examples out there. I bury a long password in code somewhere and use it as the password to encrypt/decrypt the envelope. Be sure to obfuscate your code or that part where the password is hidden to thwart decompliers.

Hi there,
I need to get the dimensions of a window's restored/normal size when it is maximized. This might sound simple, but i have spent hours trying different SDK and CWnd functions, and searching this forum and others, but to no avail.
The only function i can find that apparently retrieves the restored window size is GetWindowPlacement() and use its "rcNormalPosition" member. However, this member does not contain the correct restored size. When i compare the value of this member to the actual size that the window was before being maximized, it is different (the size is a lot bigger, and the top-left is a -3 value for some reason).
When i click the MDI window's restore button it restores the window to its previous (restored) correct size. Therefore the SDK obviously stores this value correctly somewhere in order to correctly restore it. Why can i not get this correct value from the SDK or CWnd please?
It seems a simple thing yet i have spent quite some time and have not found the answer.
Any help for this would be very much appreciated. Thank you.
Regards,
James

I think the values in the WINDOWPLACEMENT structure are opaque, in that they don't relate to "real" coordinates. We have the same requirement for one of our apps, and what we do is call GetWindowPlacement when closing the app, save all the values in the structure, and on startup, recreate the WINDOWPLACEMENT structure, and call SetWindowPlacement.

Hi Graham,
Thanks a lot for replying. I think that you are correct about the values of the WINDOWPLACEMENT structure not being "real".
My trouble is that the way in which we store window information, i cant currently store the WINDOWPLACEMENT structure and then restore it using that. We only store the starting point (x,y) and dimensions (cx,cy), and also whether it is maximised or not. Unfortunately i am limited to this and so i really need the actual restored point and dimensions.
Im sure that there must be a way to get this information, as the window is correctly restored by the SDK and so it must be able to work out the window's original placement info (even if it uses the WINDOWPLACEMENT structure to determine the "real" dimensions).
Thanks again for your suggestion, much appreciated.
Any further suggestions or help on the problem would be greatly appreciated.
Thanks,
James

OK then, my other suggestion would be to handle the WM_SIZE message in the top-level window, and keep track of size information there. One of the parameters of the WM_SIZE message says what kind of sizing has happened, so you could store both the state and normal size in response to this message, and then use those values instead.

Hi Graham,
Thank you for your second suggestion.
I have just figured out my problem. I was calling GetWindowPlacement() for the each bar/window in the mainframe to get their placement information, but it was always returning the maximised dimensions. I then attempted to call GetWindowPlacement() for the window's parent FRAME instead, which actually gave me the correct dimensions. I didnt realise that this would make a difference but obviously it seems to. It makes sense i guess.
Anyway, thanks very much for your assistance! Much appreciated.
Regards,
James

Hi
Is any way I could get notified when a HID device is conected/disconnected to the USB port? So I shouldn't be checking each 3 seconds if my device is connected?

Hi,
I am placing a bitmap on a button using LoadBitMap and SetBitMap.
The problem is that when I draw the bitmap, I want the background to be transparent so it will appear nice on the button.
From some reason, the "Draw Opaque" is checked by default in VisualStudio on the "Image" menu and I can't change it.
How do I use a transparent background on a bit map I am drawing.

Hi,
my name is marco and i am working for Project Zero.
Project zero has taken over the Development of Soldner Secretwars.
I can`t tell much here, but from jan. we get a budget for it.
Jowood finally came true.
I am the lead coder, wich is great.
The bad side is that i have to code the new mod in c/c++ by myself.
Is there a tool that MAPS globals in a DEEP NESTED class archy?
example:
struct SOLDIER{} * t_SOLDIER;
class a,public b,public c
{
a() :c:var_a(0) {this=t_SOLDIER;}
};
Not exactly correct but who cares, i see this mess every day. 
What i want is a tool to map all vars,globals,classes,structs.
Becouse i need to create a overview of +-2500 code files.
If you wanna help...... send me a email.
You will run away after a week
And u need math!
direct-x math!
i need 2 bring orde into this chaos.
Any sugestions about tools are verryverryverryverryverryverryverry apreciated.
Bye and thanx.!

yes,
i use visual c/c++.net2005 (coded a build booster to speed it up).
The whole project is build with make_master.bat wich calls various makefiles.
I can also load it in dev studio and build but this is slow...
it takes 20 minits on my amd64 1gb ram to build soldner. 
the c/c++ code calls python,xml (mixed.....)
Its real spagetti code....
And we have lots of fun!
i wish i had some more c/c++ college`s
anyone voluteering?

Only 20 minutes? You are lucky. Our product takes 2 HOURS to build. And that is on damn fast machines (2.8 Ghz or faster).

i wrote a build booster, coz as usual Micro$oft doesn`t tae in account that i use a 1Ghz++ pc.
Its just verry simple: create 2 structs:
process_info and startup_info
void RunProgram(char * path,char * appname="tryme.bat")
{... u know how it works...
}
Set thread priority to what u think is safe
And call a Make_master.bat or Make_label.bat so each process that gets called from those bats... will run at high priority.
its a lame way to boost compiling speeds.... But hey i am a friend of simple solutions

Can anyone tell me whether CopyFile APIs of win32, calls NtCreateFile native API for its internal implementation or not? and if yes, how can both of these calls can be related to each other, i mean looking at NtCreateFile and CopyFile API's it it possible to identify which NtCreateFile is called due to CopyFile?

I would assume that CopyFileW would call CopyFileExW which would call CreateFileW which would call NtCreateFile. CopyFile/CreateFile etc are Win32 User APIs (kernel32.dll), while the NtCreateFile would be a lower level system API (ntdll.dll).

I have successfully implemented sending a fax into our software but I'm having a problem retrieving the status. When I submit a fax (FaxStartPrintJob), I get back a job number. The first number was 1, and it's always going up by 1 each time I send. Seems fine. If I call GetFaxJob though for any of those IDs, I get an invalid parameter error. If I go into the fax console and look at the properties on a fax, it displays JobID's like 0x0201c5fa84b842a6 which are way to big for a DWORD. Here's the code in case I did something wrong. Are the job id's in the fax console right or should they be 1,2,3... like the ones I got when submitting the fax?
HANDLE hFaxServer;<br />
PFAX_JOB_ENTRY pFJE;<br />
<br />
if (!FaxConnectFaxServer("", &hFaxServer))<br />
{<br />
writeOutputString("MSFax - Unable To Connect To Server\n");<br />
return;<br />
}<br />
<br />
if (FaxGetJob(hFaxServer, nJobID, &pFJE))<br />
{<br />
}
Thanks,
Sean Capstick

Why don't you try calling FaxEnumJobs and compare the information in the queue with those you already submitted. Maybe you cna see how the jobs get numbered.

Hi
Is there a way to detect when windows receives a new ip-address from a DNS, or even better, hook the actual call to the DNS?
I've gone through windows hooks and messages, but without any luck.
