What do you do in your top level window to be notified that the screensaver has become active? I want to respond to this and temporarily disable a periodic event.
Likewise, what notification is received once the screensaver has been deactivated and your window is now 'visible' again, even though your window might not be the one that is the 'active' window?

How about SetWindowsHookEx(WH_FOREGROUNDIDLE, ...) or SystemParametersInfo(SPI_GETSCREENSAVERRUNNING, ...)?

1. I could not see that the WH_FOREGROUNDIDLE would directly apply to the screensaver. I suppose if this event is detected, I could create a different timer to check the SystemParametersInfo every 30 seconds or so to see if the screensaver had become active.
2. This requires polling and is not a notification. I am looking for something sent to all 'top level windows' when the screensaver becomes active.
I did find this one, WlxScreenSaverNotify, but I don't want to replace the GINA DLL.

My bad.

When a screen saver starts, it posts a WM_SYSCOMMAND message to the foreground window with wParam equal to SC_SCREENSAVE.

I saw this article in the MSDN, hope it helps.
HOWTO: Know When Your Screen Saver Starts
ID: Q238882

If you set a system wide hook for mouse and keyboard when you detect the screen saver has started you'll be able tell when the screen saver has stopped as it is mouse and keyboard activity that they respond to.
Remember that for a system wide keyboard/mouse hook the hook functions need to be in a dll.

Thanks. I already hook the low level mouse handler, I can just add a low level keyboard hook to that same DLL.
|
|
|
|
|
 Now all I have to do is hope that EVERY possible application that has the foreground focus will post the SAME message to all other top level windows, and then we can all be notified when the screen saver starts. It still does not seem like a sure thing for every window...

Hi.
I'm tearing my hair out here. 
I am trying to debug a .exe on a remote PC. I have done everything mentioned in article "Remote Debugging in MSVC++ 6.0" and in the MSDN help, but get the following when I try to debug...
"Unable to start debugging, access is denied. Verify that you are an administrator or debugger user". I am logged on the remote PC as an administrator, but with a different logon name to the one on my local PC (where I'm also an administrator). Surely this shouldn't matter?????
Also, when it says "verify that YOU are an administrator..." what does it mean by "YOU" who's it looking for????
Any help much appreciated!
Thanks!!
JC.

Sounds like the user is the problem. I think you need to add the user you are logging on to the development machine as to the administrator or debugger group on the target machine
|
|
|
|
|
you can use the following command in the command prompt window:
net use \\remotePC /user:remotePC\user_with_admin_rigths *
That should be done before any connection to that remotePC.
The subsequent connections will use user_with_admin_rigths credentials.

Thanks guys!
I've got it working now. I just needed to type -tcpip and -anyuser after the msvcmon.exe in the command prompt on the remote PC. It seems to default to using pipes.

Hello boys,
I´m novice programming in visual C++ and I don´t know how can I convert an hexadecimal string to a byte array. Can you help me please? 
Thank you very much 
|

|

char c = 0;
char str[] = "7D";
sscanf(str, "%X", &c);
printf("c = %d = 0x%X", c, c);
TOXCCT >>> GEII power

Thank you very much for your reply, 
I don´t kown if what you sent could be useful for my purpose, anyway I´m novice and I could be probably wrong. As long as I can see in your code I can´t create a BYTE array, only a char array. Is this correct?
My actual problem is that I have an hexadecimal Hash string (40 elements) and I need to convert this Hash to its equivalent BYTE array. 1 Byte = 2 hexadecimal characters, so I need 20 Bytes in my BYTE array.
The problem is that this Hash can´t change during the conversion!!!
I´m using some Cryptography functions (CryptCreateHash, CryptSetHashParam, CryptSignHash, etc...). I have to set the hexadecimal Hash string as the Hash to sign with the CryptSetHashParam function, but first of all I need to convert this Hash to a BYTE* element.
Thank you very much for your patient

One way to do it is to use strtoul() on every two characters (while specifying 16 as the base) - looping through to the end of your source of hex chars (need to check for % 2 of course). As each value is returned, you can add them to a CByteArray or a fixed sized array of bytes.
Let me know if this doesn't make sense.

Hello,
I have proved your solution with this code:
char *demodemoHex = "5863d9e4cbdf522eaa62e0747fceb1c5b249ba13";<br />
char **stopString;<br />
BYTE *hexArray = new BYTE[20];<br />
int j = 0;<br />
char hexChar[2];<br />
<br />
for (int i=0; i < 20; i++)<br />
{<br />
hexChar[0] = demodemoHex[j];<br />
hexChar[1] = demodemoHex[j+1];<br />
hexArray[i] = strtoul(hexChar, stopString, 16);<br />
j = j + 2;<br />
<br />
}<br />
<br />
cout << "@@@@ hexArray value visualization" << endl;<br />
for (int i = 0; i < 20; i++)<br />
{<br />
printf("%2.2x ",hexArray[i]);<br />
}
And the output is:
@@@@ hexArray value visualization
58 63 d9 e4 cb df 52 2e aa 62 e0 74 7f ce b1 c5 b2 49 ba 13
It seems to be OK!!! I´m going to prove the output hexArray with some Cryptographyc functions. I will tell you what happen.
Thank you very much!!!

I have proved your solution with some cryptography functions (exactly CryptSetHashParam ) and it works correctly.
Thank you very much to all the people that helped me, specially lynchspawn

A BYTE is nothing more than an unsigned char.

what i am seeking is some guidelines.
Picture this:
I have a team developing the same application , and we use VSS.
We do not release major Versions, we distribute our application by releasing small builds, and every time i send one build to the testing people, i will wait for their feed back while my team starts new features (for the next build).
Now, if i place a "label" in VSS marking the "beta build" and my team starts woking again, the label will not do me any good because its does not reflect the build that will be sent to the customers. On the other hand if wait until i have the build ready to send to the customers, i can not place a label on VSS because the code will have changes made by my team after i send the build to testing people.
For this to work this way i would have to give "vacations" to my team whil in testing fase.
Not very good ... 
How do i solve this?
How do you test a build and work on the next without multiple copies of the source code?

I put in a #define VERSION_NUMBER "put something here" in my stdafx.h file. Then I use VERSION_NUMBER in my about box, or anywhere else I need to use it. But maybe in your case it would be best to just check the project out each time and check it in with a comment

Yes , but the problem is how to control the changes that are made after the build get sent to testing.
IE:
I send a build do testing and wait for feedback.
While i am waiting, i what my team to keep working, but if they change the resources (for example), i will have no way to solve any bug in the build that was sent to the testing whitout the changes that have been made geting in to.

Has anyone suggested Branching?
Basically, we have the "main branch" which contains all new development. When I want to put a version into testing phase, I create a branch in a "Releases" folder and call that branch "Version A". I continue working on the main branch.
Then, in testing, version A has a problem. I can create a new project off of Version A, and make the changes only to version A. Then recompile, continue testing.
Once you confirm that you want those changes from version A in your main branch, you merge in the changes from Branch A into the Main version. Now main version has the fix you found, and your new development, but Version A is at a stable stage that it can be deployed.
PS I know you guys wrote back in May, but I was searching around for info on Source Safe Command Line stuff. Cheers.

Please, I need an orientation about how may I capture screen in format swf
("Flash"). I found an Unix application, vnc2swf, which make flash animations
from the VNC server data received from a machine running Windows, but, I need to do it using a C++/MFC program running on Windows...
Some sample code, any pointer, some indication?
Perhaps capturing and storing in AVI format (memory expensive) and, after,
convert it to SWF? But, how?
I dont know how or where may I search about it! 
Thanks!
