breaking nicely out of nested loops
by deepzero- 5 replies

hi, everyone seems to hate on the use of "goto" commands in c/c++ and i dont like it too much myself, but i dont see any other way with nested loops: good: for(...) { if(...) break; } not good: for(...) { for(...) { for(...) { if(...) goto done; } } }done: ... any "better" or "cleaner" way, avoiding the goto commmand?

Reflection - The Java Reflection API With the introduction of Java Beans was also the birth of Reflection (formerly " Introspection ") forced initiated because objects were previously found only in static structures. This in turn meantthat the classes had already at compile be available. Because of this fact but the genericapplication form request can not be extended to the interface of a plugin, corresponded, it wasdecided to introduce a new technique? Introspection (later Reflection ). The term Reflection here means that programs which are a generic design to be able put in for herclasses (unknown such as by direct user input) to create instances of objects. The Ref…

Calling invokedynamic in Java DynamicIndy There is no way to invoke invokedynamic using the Java language. So testing invokedynamic is not that obvious if you don't have your own dynamic language. I've developed a small class DynamicIndy that uses ASM 4.0 (not an official release) to generate a static method that calls invokedynamic. These static method is after converted to a MethodHandle that can be called in Java. invokedynamic

I need help to uncap fps in games
by iVanisher- 2 replies
- 5.2k views
Hello everyone. The reason of this topic is because I want to make a program to uncap the framerate of some games. I got inspired when I saw some patches achieving unlimited fps on games capped at 30 fps. (Blade Kitten, Transformers: War of Cybertron, Star Wars: The Force Unleashed, etc). I tried to do a d3d hook and also tried to look at those patches in Olly (some of them were packed with PECompact/UPX) but unfortunately my reversing skills are still too weak to know what they did... so in the end I had no success... I'm asking for some help as there are very talented and experienced people here at tuts4you. I really want to know how to do this, specially for learning p…

String compression algorithms

String compression algorithms: 1. First simple algorithm: Input string "Acccc"; We store first 2 chars "Ac" + a char: - first bit should be set whit 1 for marking that we have a compression here - rest of bits will filled whit numbers of duplicates - under this case 3 "Acccc" -> Ac[3] 2. Second algorithm: Input string "the Udrea, the Basescu"; * We store "the Udrea, " + First char: - first bit should be set whit 1 for marking that we have a compression here - rest of bits will filled whit the lenght of duplicate string - under this case Second char: - all bits should contain the position from where to take the string - under this case 11 "the Udrea, the Basescu…

As it happens, I'm not the first to look into this particular algorithm: the full listing of the decompression routine with some annotations is available on a Chinese blog. I've already been able to write a "poor man's compressor" for it (well, with compression rate 0 so it actually increases the file size), but I'd like to know what algo it is. I suspect it's a readily available open source algo but I have no experience whatsoever with compression algorithms so I figured someone here might know more than I do about the topic. I'm also attaching a small file packed with it. When decompressed, it's actually a resource file with some strings and a bitmap in it. packed.zip

Loader race issue
by birt- 6 replies
- 5.6k views
So, I have this packed service that I need to patch at runtime without actually running a loader. I took the easy way, I wrote a DLL and added it to AppInit_DLLs, returning 0 from its DLLMain if it's trying to attach to a different process. So far so good. Next step was to patch the process. Since at the time the DLL is loaded, the exe image isn't even loaded yet, let alone unpacked, my solution was to start a thread as soon as the DLL is attached to the process and enter an infinite loop. Inside the loop I monitor a memory location (one of the patch locations actually) directly (not via ReadProcessMemory() since it's in the same address space) and when it has a certain v…

Hope someone can give me a hint, because I have the following code copied from reflector(VB.NET) into vb express edition 2010, but I have a lot of errors, so I started fixing the code, but i ended with an error, which it seems I , not yet, can't resolve myself.

Hey Guys, I am having some trouble with patching a file in Visual Basic 2008. The idea is like that .. 1-Store File In The Program Using "Resources" .. 2- If The Program Is Runned ..

hello guys, I can understand if you do not want to help me but ... I have a program that it uses hardware ID to generate a license, similar to armadillo... however, a larger it is based on the network card for hardware-fingerprint ... I know this because when I change the MAC address, it also changes the hardware-fingerprint ... only it is not only that, but when I try to log in via wifi or cable, hardware id changed and I can not login .... when I change the MAC address of a network card, the hardware-fingerprint changes, but even if I put the two MAC addresses match, the hardware id is never the same ... you will be able to understand? I was wondering how it obtained th…

[Delphi] Store Function in Resource Section of Executable

hi, I am trying to store a custom procedure within the resource section of my executable. Then, I hope to call that procedure from resource. I have a basic example working and I have posted full delphi source code for this example. However, there are limitations. I am having trouble retrieving return values from Windows API. As you can see in the code below, if you compile both executables with the comment in the builder intact, then run the builder, next the stub, it works perfectly. However, if you remove the comment in the builder to assign a local variable to the result of a Windows API, then run the builder, next the stub, it results in an error Builder: p…
