Hi Forum,
I am looking for application that could block another application when loading. Now on messenger like Yahoo and MSN are everywhere in my office. Some of them use it for official communication but the rest just for fun which of course decrease work performance. The management doesn't want to block all the user but some of them should be.
Does anyone knows what kind of application to help me or other references for developing small application would be appreciate as well
Regards,
JClick

Are you in an Active directory? If so, try Group Policy
I guess you could prevent these programs from being installed, and started. MSN messenger will be a bit harder to remove, since it's MS idea of world domination. But Yahoo should not be much of a problem..

hi all
thanx alot for this grate codes and projects
i want your help in assigement by C
i tried in it but there is always a wrong outputs!!!
can i get help?
this is the problem ;
1. Description
This assignment is to be done individually. Write a C language program to implement multithreaded matrix multiplication using Pthreads as described at the end of chapter 4 (page 149) in the textbook, with the following differences:
• Create a separate worker thread to compute each row of the result matrix, instead of a thread for each element.
• Do not initialize the contents of the A and B matrices statically. The A and B matrices will be initialized by reading data from an input file (see notes below). A seperate input file will be tried for your assignment grading. You can create your own test data for debugging and testing your program beforehand.
• (optional) Be able to process multiple sets of input matrices by continuing to read data in the specified format (described below) until you encounter an input line containing a single hash mark (‘#’) instead of an integer value for M (first dimension of the A matrix). If any other character than a hash mark is specified, output an error message and terminate the program with a non-zero return code. Each set of data processed must be labeled to indicate which set of data is being output (e.g., Set 1, Set 2, etc).
2. Input and Output
The input file will be an ASCII file containing numbers that define the dimensions and contents of the A and B matrices for which a matrix product is to be computed. The first line of the input file will contain two numbers specifying the dimensions of the A matrix (M x K). Following that will be M lines, each with K numbers, representing the elements of matrix A. Next will be a line with two numbers specifying the dimensions of the B matrix (K x N). And following that will be K lines, each with N numbers, representing the elements of matrix B. For example, suppose that matrix A has 2 rows and 3 columns and matrix B has 3 rows and 4 columns, as follows:
Your program should print the contents of matrix A and matrix B. It should then print lines showing the thread ID numbers for the worker threads it creates. Then it should print the contents of the result matrix C. The output from your program for the above input should look similar to the following:
Set 1 Matrix A:
1 2 3
4 5 6
Set 1 Matrix B:
3 5 7 9
8 6 4 2
4 3 2 1
Created worker thread 15823744 for row 0
Created worker thread 26375040 for row 1
Set 1 Matrix C = A x B:
31 26 21 16
76 68 60 52
2. Implementation
The project description in the textbook contains a number of implementation hints. In addition, the source code for the sample program shown in the book on page 133 can be found in online. It demonstrates the usage of Pthreads functions for simple thread creation.
You will need at least the following include files:
#include <stdio.h>
#include <pthread.h>
You may assume that matrices will have a most 10 rows and 10 columns. You may use global variables for sharing memory among the threads. In order to successfully compile your program, you will need to specify some options for Pthreads on the gcc command as follows:
cc -pthread -lpthread assign2.c
Be sure to adequately comment your program, and pay attention to format, program structure, and programming style.
Notes:
• In the above example output, the Thread ID value is actually an address of an opaque thread data structure that is implementation dependent on each OS version (e.g., Unix, Linux, etc). To get to the actual thread number would make your program non-portable! That is, the actual Id number is saved in different places in the data structure on different systems. For the purposes of this assignment, simply getting the unique address of the thread data structure is sufficient. You will see the same address, perhaps in different orders, over and over as you iterate through each set of matrix data since the system reuses the same storage for creating and deleting threads during execution. Likewise, you will see the same address if you simply create a thread, terminate it and then create another new thread (i.e,. you must create at least two threads, running at the same time, before you will see a different address (Thread ID) listed).

I am trying to get a value of a certain registry key and store it in a char array. I do it like this:
<br />
char buf[4096];<br />
HKEY pHKey,dKey;<br />
LONG tmp_reg1 = RegOpenKeyEx(HKEY_LOCAL_MACHINE,"Software",0,KEY_READ,&pHKey);<br />
if((tmp_reg1 != ERROR_SUCCESS) || (pHKey == NULL))<br />
throw(string("No proper registry key (1)"));<br />
LONG tmp_reg2 = RegOpenKeyEx(pHKey,"CyberLink",0,KEY_READ,&dKey);<br />
if((tmp_reg2 != ERROR_SUCCESS) || (dKey == NULL))<br />
throw(string("No proper registry key (2)"));<br />
LONG tmp_reg3 = RegGetValue(dKey,"PowerDVD","InstallDir",RRF_RT_REG_SZ,(LPDWORD)REG_SZ,buf,(LPDWORD)sizeof(buf));<br />
if(tmp_reg3 != ERROR_SUCCESS)<br />
throw(string("No proper registry key (3)"));<br />
However, when I start the application, it crashes giving me the following error (My Windows is in Polish so I do not know if I translate it properly) :
Unable to find entrance point of the procedure RegGetValueA in library ADVAPI32.DLL
I use Windows XP Home Edition, SP2, Visual Studio Express 2005.
Thanks in advance

RegGetValue() is not present on XP Home. Your type and buffer size parameters are also wrong, you're casting integers to pointers, so the call would crash even if the API were available. You can use RegQueryValueEx() instead.
|
|
|
|
|
Will RegQueryValueEx() work in both XP and Prof. ?
|
|
|
|
|
Every help page on an API - for example this one[^] - tells you which OSes the API works on.

I can not access dirves on my local computer using a UNC address(\\local-computer-name\share-name). Windows XP is installed and i am in my own Workgroup. I also has set 'share this folder on the network' and 'allow network users change my files'.
I get the message '\\local-computer-name\share-name' is not accessible,....

Hi all,
Would you help me to change the default sound device with an api or something else...
Thanks...

Hi to all!!
when the windows xp home edition starts then before completely logging in there comes a error message that memory at a particular address that they give could not be read.so kindly post me the solution for this.one time my o.s was not being logged in and i had to run it on safe mode.so please help me out!!!!

Check your error log, is there a more specific error message?
Trinity: Neo... nobody has ever done this before.

I get the following error when trying to set advanced settings for a COM PORT from Device Manager: "You must have write priveleges in the registry for this device in order to modifiy the device's advanced settings.". I am running XP Pro and had no problems do this up to last week. Another computer in our office has the same issue. Have not loaded any new software in 2 weeks.
Able to open regedit but can't change any values. I was able to last week.

I did some searching about your problem and found a few results:
1. Make sure that your firewall (if you have one) isn't blocking registry access. If you do have a firewall, is it ZoneAlarm?
2. Try booting into safe-mode and see if you can set it then.
These are the most common solutions. Hope this helps.

Thanks for your help.
Still unable to access advanced settings in safe-mode.
Does not appear to be a firewall problem (I do not have ZoneAlarm) because I have 5 USB-RS232 adapters and can access advanced settings on 1 of the 5.
The 4 that I can't access are missing 3 registry keys:
ForceFifoEnable
RxFIFO
TxFIFO
Replacing these key allows access to the advanced settings in the Device Manager.
Big question is how these keys got deleted on 3 XP machines on the same network.

Ok, I did some more searching but I didn't find anything new. The only thing I can think of is to check your computer privileges (assuming you are an Administrator) just to make sure nothing accidentally changed.

Malware could possibly corrupt registry keys, also any software that you might have uninstalled that used those same keys.

Thanks for your help.
I have administrator privilege, I had to change some of the privileges in REGEDIT to allow me to change values.
It's just weird that's it happened all of a sudden and on three computers. We regulary access the advanced settings on all 3 computers and just found this problem yesterday.
SpyBot, Webroot Spy Sweeper, and Symantec Antivirus didn't find anything.

Tnx. for the given link
but finding Error in scripting , not getting following
Set objUserLDAP = GetObject("LDAP://CN=myerken,OU=management,DC=fabrikam,DC=com")
What I have to set over here !
Me and Program both have logical waves.

Not really sure, and I can't run that script from the computer I'm at right now but I assume (yea I know)
CN == User?
DC == Domain Controler?

tnx. I try out his one also letsee...

I want to play a (trusted) game online that requires me to allow 4 incoming TCP ports in Windows Firewall. None of them appear to be used by Trojans, not that I run any programs I don't trust anyway. Is it safe to open the ports?
Thanks so much,
Pete
