 Hey I just realize I am really stupid !!!
Right now about 3 hours I am trying to find on internet how to make "Self-Executable" file. I need to acces data connected to exe file itself. That means I need 2 applications, One which will create the self-executable file and add the data to it and second will be the applications which will expect data in itself. But how to do that???? I have no clue.
I'm working on simple blowfish decrypting applications and I want the final ,after encryption file to decrypt itself.
What is the structure of that file. I heard that I have to simple add the data I want to connect to the file at the end of the file and than I can work with them, but that doesn't work because than I cannot run the application.
Please help!!!!!!!!!!!11111

how about using an EXE packer ?
that way your application will be the decriptor and it'll just access the encrypted-file...

What do you mean with EXE Packer? Is there any link for that.... Thanks
|
|

an Exe (or sometimes PE) packer can take an executable and sometimes (you're looking for these sometimes) data-files and pack them all up into a single compressed/encrypted self-containing executable.
for example: http://protools.anticrack.de/packers.htm

If you allow the question... what do u need this for?
It is quite an easy thing.
Make the first problem put some files as resources in the second file, and the second file then just has to load these resources and write them to the drive... quite easy!
Don't try it, just do it!

Hi there, I'm in the process of writing a multi-threaded webcrawler using VC++ 6 and MFC. I've got the basics down, but I can't help feeling like I'm going about it the wrong way.
I've got a Doc/View set up and when the user chooses some options (base URL / how many threads to launch), the document launches the first thread. To do that, it sends a message (using postthreadmessage) to the worker. The worker then goes and downloads the first page, parses it for links and sends a message back to the document via the view as I wasn't able to send them directly to the document...
As a side note, that process feels a little clunky. It seems logical that you'd probably not want to send messages direct to the document, but I couldn't see where else to do it; afterall, the document's storing all the links the workers download.
...anyway, once the document knows there's an idle worker, it gets all the links from the worker (calls a member function on it to retrieve the data - should be safe as the worker is idling now?) and adds them onto the (end of) master list. Since the document knows there's now a free worker, it pulls off the next link on the master link and launches the worker off again.
Does this sound like a reasonable way of doing things? I'm not sure quite why, but it feels a little in-elegant, and I can't help feeling there's probably a better way of doing it?
Any suggestions / comments would be most welcome!
Cheers, Jon

If I were you I'd consider writing/using a thread-pool.
have the first thread start running with a job of downloading the first page. then perform your default processing on it which is to parse for links .
then, fill the thread-pool's job-list with jobs per each url, and so on.
add a depth count to each job so that you can limit them.
before a thread fills up the thread-pool's job-list with more urls to investigate, have it post some data into another list the doc/view is incharge of so that the user can get a sense of 'whats happening'.
p.s. - a thread pool is a simple structure of X threads that wait for 'jobs' to handle. they share a single 'list of pending jobs' and whenever a job exists in the list, an event is set and the first thread to catch it will be the one to remove that job from the list and handle it. it requiers some synchronization (locking list, waiting for input, waiting for all threads to destroy themselves, etc) but if you do it generalized it's worth it.

why don't you download a good hindi font like 'shusha' and create a CFont and set the font of CEditView.

Does anybody know how you can insert your application to be by default in winodows shorcut menu. That you can right-click on your file and select to do something with it.
Something like WinZip: That you can right-click on the file and select for instance to compress the file. Thanks

I have a requirement to create MS Excel workbook files as part of a reporting application I am developing. I need to produce these files from within a Windows service. I cannot use automation so I need to create the files directly. I have been looking on the web for open-source, or commercial Excel file creation library and have come across a few possibilities. I am evaluating a couple options right now, but before I dive too deep into this, can anyone suggest a decent Excel file creation library for C++. (Again, commercial or open-source.)
PS. I must write to a native Excel format that supports multiple worksheets. BIFF8 or better I believe.

Excel files can function as an ODBC (and JET) data source, so could it be that you can write an Excel file by using the same procedure, only reversed ?
Is there are reason on why you can't use automation ? It can be kept simple and efficient, with a minimal overhead, if that's a problem..

I really hope to do that also, so I'm hoping you get a good response. I've used the alxBase classes I found on this site for .dbf's that writes directly to the file and is super-fast. I have to give the user an option though between .xls and .dbf (for import). I'm using the automation for excel and it's about 10 times as slow as the alxBase classes which are writing directly to the file with the correct offsets.
If it's broken, I probably did it

For all database functionality on MFC, I first suggest you read the article by Stefan Chekanov found here[^].
The Access file acts as a data source, and by using Chekanov's article and the classes introduced there, you can execute plain SQL-queries to retrieve custom data sets, and then use a by-index or by-name methods to retrieve the data from the resulting set. After you have the data in a local variable (CString or similar), you can use Dialog Data Exchange implemented by a CFormView-derived class to move data into the form's controls and vice versa.
To write data into the database, use the Field function to get a reference to the CDBField, then use the overloaded assignment '=' operator in CDBField class. Remember to prepare the database for updates first, and then flush the update operations when finished. Otherwise an assertion might occur.

Which means what? Are you getting compiler, linker, or runtime errors? Please elaborate.

As far as i know
Platform SDK is a set of header files, lib and other such stuff for developing windows application without any MFC or ATL.
Service Packs (for VC++) are generally for MFC, VB and data access(DAO,ADO)
C makes it easy to shoot yourself in the foot; C++ makes it harder, but when you do, it blows away your whole leg

servicepack is a cumulative fixes for known bugs and problems.
sdk is a downloadable platform for developers.

Well, SP5 is not that old. It's safe to say that they would only be concerned with critical issues (e.g., security, data integrity) at this point.
