So I have to search for the string "value=" and frm there to extract the -44 value? Is tht wad u mean by keeping the bits?
My prog now is currently reading all the info but I donno how to screen away the first line, and read the -44 frm the second line.
Thanks alot for ur valuable reply though. Appreciate tht.

Sort of...
What I mean is that you read in every line.
Read a Line;
Does it start with Value = ?
Yes...
Does it have Integer32 next?
Yes...
Grab the -44 part, and keep it somehow. A list, email it to your best friend, whatever you want.
No...
Move on to the next line!
By "keeping the bits", I mean "do whatever you like with the information". You must be interested in it for some reason. That will influence what you do with the information.
I did notice on rereading your question that there is a phrase "Integer32". Are they all the same type?

sorry for the very very late reply...
ya, there's always a Integer32 whenever I run the prog and saved it to a text file. Tht's the format of the output.
What if I had 2 lines tht have Integer32 but different values? how am I supposed to extract the values? Fo e.g. like the one below:
Variable = .iso.org.dod.internet.private.enterprises.9.9.273.1.3.1.1.3.1.8.105.118.116.108.95.97.112.49.0.2.45.4.155.81<br />
Value = Integer32 -39<br />
<br />
Variable = .iso.org.dod.internet.private.enterprises.9.9.273.1.3.1.1.3.1.8.105.118.116.108.95.97.112.49.0.32.166.80.182.220<br />
Value = Integer32 -39<br />
<br />
End of MIB subtree.<br />

In the example you give, the Value is the same for each.
You're doing the same thing... Just loop through the file, reading one string at a time.
If it's blank, move on.
Then take turns making sure the line starts with variable, or value, then interpret the rest of the line as you want.
I'm guessing you're meant to store the Variable name, matched against the Value value in some sort of map, or even a database, then look up pairs later on in your program.
Or,
If you just want a list of values, read each line, and if it doesn't start with Value, then move on to the next line.
How you handle the imput as it comes really depends on the job you're doing - and that question can be solved by reading your spec sheet, talking to yout customer or manager?
From the Variable names, this doesn't look like a hobby project. I'm sure there's someone who can tell you what they want done / kept from this input. From there, just write the code (with test cases, etc).
At the moment, it sounds like you're not sure what you're meant to do with this data - and that's something we can't help with.
Good luck,
Iain/

Hi Cabomba,
Can you tell me:
if the "Variable =" and "Value = " are on the same line or on different lines.
Is there only onw variable or are there multiple variables.
If multiple, do you need the value of each of them (like reading them into memory for later usage in your program) or only of a specific variable
Can you use MFC?
Knowing this, the problem should not be very difficult.

the "variable =" and the "value =" are not on the same lines. To say the the truth, I'm using snmputil to get the MIBS of the signal strength of an AP. And the signal strength is "-44". so I was trying to extract the signal strength and put it into another file for reading.
but I'm not sure how to get rid of the first line which is the "variable =" line.
Currently, there's only one integer variable in the text file, it's such a pity tht I cannot attach the text file here but it's the same as the one coded.
sorry, I don think I'll use MFC, but to stick with C/C++ prog. Thanks for any help!

When you read a line from the file containing "Value =", just skip to the 19th position of that line and read the remainder of it as an int.
Another option might be to skip to the end of the file, go backward 3 bytes, and read the integer from there.
Of course these will fail in many different ways, but since you did not provide any other requirements or constraints, better solutions were withheld.

Do u mean tht I should try to use a method to find "value =" then frm there read the integer value of -44? I'm not sure if this works but I'm gonna try and I'm not even sure if I can try successfully or not cos I nv tried it b4 and my prog skills sux..haha! But thanks for ur reply!

Well, if there are only two lines of text in your file, you don't even need to do that. The first line can be read and just discarded.

Thanks for ur reply but how do I "ignore" the first line after it is being read? Or how do I discard it?

How do you ignore any value/variable? Just don't use it. Read the first line from the file. Read the next line from the file. Voila! The firt line has been ignored.

Tried downloading a file on a specific location in a Non-proxy environment using InternetOpenURL() and InternetReadFile() API's. This worked fine.
But when i try the same in Proxy Environment it fails. I tried doing HttpQueryInfo() and then checking the status for HTTP_PROXY_AUTH_REQD. This is successful but when i set the username and password for Proxy Authentication and retry, it still gives me status as HTTP_PROXY_AUTH_REQD. If I continue downloading the file then junk characters are downloaded and written to the file.
Need help to make InternetOpenURL work in a Proxy Environment. (Please note that Proxy Server Details are not present with my application and i cannot bypass the Proxy Server)
Thanks in advance.

Hi all,
May I know how to calculate the number of times a character occurs in a string? Are there any function returns the number of times a character occurs in the string?
Thanks.
Regards,

Made function, no AFAIK. But you can code it quite easy. Take the String as a vector and make a for with an if and a counter. When you find the character... +1, when not... next element.

hi,
I want to run only single instance of my application like
windows media player . can any one told me how it is possible

One of the ways in to create an inter process Thread Syncronisation object like semaphore and lock it when you start the application and unlock before exit.

Use a named mutex...
HANDLE hMutex = CreateMutex( NULL, FALSE, _T("MY_UNIQUE_MUTEX_NAME") );
if ( WaitForSingleObject( hMutex, 0 ) != WAIT_OBJECT_0 )
{
CloseHandle( hMutex );
// failure case -- someone else already owns it.... (my other instance?)
exit here!
}
.... run program
ReleaseMutex( hMutex );
CloseHandle( hMutex );

There is more than one article on codeproject on how to do this.
Search for singleton, single instance, etc.

I like to create a out of process(seperate application) webbrowser from one applicationa and want to control this webbrowser from the main program.
Any idea or link would be very helpful?
Thank you.

The are a lot of ways of course.
You may use a form of Interprocess Communication http://msdn2.microsoft.com/en-us/library/aa365574.aspx[^]
or you can build a COM out-of-process server (COM is a rather big topic however).
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

hi all,
I am using ORCA to validate the product key in C# 2005 windows application.
i am using the following C++ code in a dll to be added to the MSI for validation.
UINT __stdcall ValidateSerial(MSIHANDLE hInstall)
{
TCHAR szPidKey[PIDKEY_LENGTH];
DWORD dwLen = sizeof(szPidKey) / sizeof(szPidKey[0]);
///retrieve the text entered by the user
UINT res = MsiGetPropertyA(hInstall, _T("PIDKEY"), szPidKey, &dwLen);
if(res != ERROR_SUCCESS)
{
//fail the installation
return 1;
}
bool snIsValid = true;
//validate the text from szPidKey according to your algorithm
//put the result in snIsValid
//the template we use is <###-####> = <xyz-abcd>; # digit between 0 and 9
//the algorithm is very simple (XY * Z + 7) * 13 = ABCD / 2
int xy = DIGIT(szPidKey[0]) * 10 + DIGIT(szPidKey[1]);
int z = DIGIT(szPidKey[2]);
int left = ((xy * z + 7) * 13 ) * 2;
int right = DIGIT(szPidKey[4]);
right = right * 10 + DIGIT(szPidKey[5]);
right = right * 10 + DIGIT(szPidKey[6]);
right = right * 10 + DIGIT(szPidKey[7]);
snIsValid = (left != 0) && (right != 0) && (left == right);
TCHAR * serialValid = NULL;
if(snIsValid)
serialValid = _T("TRUE");
else
{
//eventually say something to the user
::MessageBox(0, _T("Invalid Serial Number"), _T("Message"), MB_ICONSTOP);
serialValid = _T("FALSE");
}
res = MsiSetPropertyA(hInstall, _T("SERIAL_VALIDATION"), serialValid);
if(res != ERROR_SUCCESS)
{
//fail the installation
return 1;
}
//the validation succeeded - even the serial is wrong
//if the SERIAL_VALIDATION was set to FALSE the installation will not continue
return 0;
}
but when i execute the above code, i am getting the following error.
error LNK2019: unresolved external symbol _MsiSetPropertyA@12 referenced in function "unsigned int __stdcall ValidateSerial(unsigned long)" (?ValidateSerial@@YGIK@Z) CustomAction.obj
i have included <msi.h> and <msiquery.h>
I am a beginner in VC++ and could anybody help me with some suggestions
Thanks in advance.
Regards
Anuradha
