Hi guys, I see some problem when using the normal GetPrivateProfileString & WritePrivateProfileString function to store lines into a file and read them.All works for normal lines without CRLF but the GetPrivateProfileString function dosen't read the stored multiline/s which was saved with WritePrivateProfileString function. Why do they differ?Write works & Read not?In this case I can not use GetPrivateProfileString function to read some entry from file. I'am using a edit control with multilines & wantreturn style and wanna save / read whole text parts to file.How could I do that in best case?Just asking before whether they are any functions I could …

Hello. During coding a keygen i have this issue. The keygenme calculates a SHA-256 which is stored in a string. After that it adds DWORD values of the SHA. Because my english is not so good to explain i put a simpler (similar) example to see whats going on. I have make some progress but i have stuck one this: Why sscanf doesnt put in eax the correct value starting from sha_256[0]. (Eax should contain the value 0x64ec88ca) How i can fix this? -Thank you

capstone vcpkg package broken?
by deepzero- 1 follower
- 1 reply

I am porting some tools over to vcpkg package manager. Maybe it's just too late, but it seems to me the capstone package on vcpkg is broken. Installed with vcpkg install capstone:x64_windows. The following: cs_open(CS_ARCH_X86, CS_MODE_64, &handle); returns CS_ERR_ARCH, because the x86-init function in static cs_err (*cs_arch_init[MAX_ARCH])(cs_struct *) = { in cs.c is Null. Which would suggest that CAPSTONE_HAS_X86 was not defined during compilation of the package. Can someone confirm this?

Hello, I'm working on a x64 Framework 4.7.2 application obfuscated with Crypto "x64 Crypto Obfuscator For .Net v7 (v2020)", I'm able to restore strings and mostly deobfuscate the app but I'm having difficulties with restore delegates. Here's an example public GForm4() { this.method_6(); Delegate108.smethod_0(Class0.smethod_0(6600) != 0); Delegate60.smethod_0(this, new EventHandler(this.method_0)); } Unfortunately most of @CodeExplorer / SnD's excellent tools give an "invalid assembly" error as it's x64? I'll be grateful for any tips or tools to restore delegates please. thanks in advance

Hi. I was solving a keyfile me today, and most of the keymaker i made was with inline assembly, because straight in C i was getting wrong values. For now i have 2 questions. I'm not on my laptop right now so i'll try to remember as much close as possible the values 1) Is possible to achieve that with the (right) way, like i have it below? : DWORD eax; eax = 0xF96A872D; /* I want the result: eax = 0xF96A78D2. Even if i "fixed" little the data types/macros i will get either eax: 0xFFFF78D2 or eax: 0x000078D2 */ LOWORD(eax) = ~(WORD)eax; 2) As my comment says i'm getting ebx = 0x18de781b and not ebx = 0xf8de781b. How ca…

Hi there! I have some questions about the library, if anyone knows help with advice 😃 1) Is it possible to replace the icon of the build file of the program through the library? 2) Is it possible to replace the properties of the build file in Properties.AssemblyInfo.cs (AssemblyTitle, AssemblyVersion e.t.c) ?? 3) How do I replace (int)integer values? 4) Can I change the .NetFramework version using dnlib? Regarding the library itself, the information is not very enough to understand it well, I will be grateful for any information!

Hi guys, so yesterday I got an access violation exception in my app by calling the function StrStrA and it seems that the memory block I wanted to check for a string was gone already = AV crash.Somehow strange because I did check before whether a address is present to check = Yes but somehow the block must be freed by anything. .if MEMBLOCK != FALSE invoke StrStr,MEMBLOCK,chr$('Sting2Check') ; <---- AV inside ... .endif Ok, in this case I did just check whether in the variable MEMBLOCK is anything = normaly the memblock address.Now, the address was still present in variable but not present for real.Now I would like what kind of function/s I can use to ve…

Hi guys, I'am using those C functions above to read / write data to file and have that problem with the Macintosh CR (see notepate status bar).In normal case I write text fields like this... db "Some Info", 13,10 db "Here too", 13,10 db "Look not!",0 ....just 3 test lins with one line break between.Now if I do use the fwrite function with it then it does write the LBs in double LBs like this... db "Some Info", 13,10,13,10 db "Here too", 13,10,13,10 db "Look not!",0 ....and not in Unix style.How can I tell the function using Unix style instead of Macintosh? greetz
