Hii! i've stumbled on PNGlib like it's the only png decoder for masm, it is the only one out there? this is the site of PNGlib http://www.madwizard.org/programming/projects/pnglib while it's considerably small, uPNG on C output is even smaller, counting kb; but some pairs of kb makes the difference on tiny intros may i ask if anyone knows another png decoder for masm? any idea is very welcome! x3

i was testing quads using multiple colors (gouraud-shade) and for some reason virtual machines either inverts the quad colors or vertex order here's a screenshot i did a test using the same exe in my host and guest virtual machine, at the left of their screen they are all three triangles, both quads at the right also enumerated the vertex order in which they are drawn in the image, you can notice the quads color or vertex are inverted on the virtual machine i tested on VMware and a friend also tested on VirtualBox, the result is the same on both, may i ask why this happens? attached the exe and source, the assembly source is here if that's better …

While looking at Nehe's tutorial for opengl i noticed that they had a masm32 conversion for these examples, the tutorials start here: http://nehe.gamedev.net/tutorial/lessons_01__05/22004/ then quickly realized the links were offline, but fortunately someone made a backup of most examples on github, including masm-converted ones, you can download them from here: https://github.com/gamedev-net/nehe-opengl/ they used some definitions files that weren't included, luckily i found these .def files in the sources of a Northern Dragons' demogroup 4k intro named Trees, it was the only place to get them so i spread them here so you can compile and follow the gr…

Visual C++ code: int processflags = 0|CREATE_SUSPENDED; // Create a child process. if (strlen(environmentstr)>2) { fSuccess = CreateProcess(processname, NULL, NULL, NULL, TRUE, processflags, (LPVOID) chNewEnv, // environment NULL, &siStartInfo, &piProcInfo); } else { fSuccess = CreateProcess(processname, NULL, NULL, NULL, TRUE, processflags, NULL, // No environment NULL, &siStartInfo, &piProcInfo); } If I attach with Olly to the new created process I get this: 02980000 CC INT3 02980001 68 7F23BF77 PUSH 0x77BF237F 02980006 C3 RETN INT3 should be there but shouldn't be actually executed…

Timer Replacer (Visual C++)
by CodeExplorer- 18 replies

Time in milliseconds of a timer: time1 = when timer started time1 = when timer proc ended time1=9182437 time2=9182437 time1=9182452 The difference is big: 15 ms! I know that 1 millisecond is much for computer performance! I've tested some code and the time in ms was not even 1 ms. uElapse [in] Type: UINT The time-out value, in milliseconds. If uElapse is less than USER_TIMER_MINIMUM (0x0000000A), the timeout is set to USER_TIMER_MINIMUM. If uElapse is greater than USER_TIMER_MAXIMUM (0x7FFFFFFF), the timeout is set to USER_TIMER_MAXIMUM. I need something much better then a timer!

Hello! i've been looking for a way to add a menu using WinAPI within the same .asm file, without using resource (.rc) files It can be done in C, like explained in this tutorial http://zetcode.com/gui/winapi/menus/ MASM32's User.lib has the same function prototypes in there (CreateMenu, AppendMenuW, SetMenu) This is for two reasons, one is because i'd like them not to be edited/spoted using Resource Editors, the other is that i want to keep everything on one .asm source file (as what i want to do is small enough) I've not seen anyone documenting how to do this before in MASM32 (or even other Win32-targeted compilers) and ran out of ideas trying, any kin…

hii! i've looked for a way to manually set the libraries that link.exe includes, by default, when i link using: C:\masm32\bin\link.exe /verbose /nologo /subsystem:windows /opt:noref main.obj it says: Start Pass1 Processed /DEFAULTLIB:C:\masm32\lib\user32.lib Processed /DEFAULTLIB:C:\masm32\lib\kernel32.lib Processed /DEFAULTLIB:C:\masm32\lib\gdi32.lib Processed /DEFAULTLIB:C:\masm32\lib\opengl32.lib Processed /DEFAULTLIB:C:\masm32\lib\glu32.lib so i tried setting the /DEFAULTLIB's parameters myself to override them C:\masm32\bin\link.exe /verbose /nologo /subsystem:windows /defaultlib:C:\masm32\lib\user32.lib /opt:noref main.obj (i was intending to j…

Bootkit/Replacing the Bootloader on Windows 10
by null_endian- 1 reply
- 4.3k views
Does anyone know of a way to edit the bootloader on a Win10 machine to force it to execute arbitrary code when Windows starts up? I'm not sure if this is possible on a new WIn10 box because I know that there are much stricter checks at bootup now. I don't care if it is a one-off as I'm trying to do a specific experiment on MY machine, it doesn't need to apply to all machines. Thanks. PS: Actually, I don't necessarily need to replace the bootloader - this code accomplishes something similar to what I need (I just need code execution control prior to everything else on the system when the OS loads) but it doesn't work for Win10. Looking for something similar.

Quick TLS Info question
by LCF-AT- 14 replies
- 7k views
Hi guy, I have a small question about TLS so I dont remember anymore and just asking now and I dont find any example file using TLSCallback + relocation to load file with dynamic base addresses. So in the TLS info table I can see direct VA addresses and no RVA addresses.My question is just whether the VA addresses gets updated like this... TLS info table VAs etc - Imagebase from PE Header = TLS RVAs + New loaded targetbase = New TLS VAs.Should be so right? As I said I am just quickly asking about it so I dont find a dynamic file I can checkout now to see it. Thanks

Comparing code
by CloneWa- 0 replies

Hi. I am trying to find the best way to programatically "map" and compare code. Basically I have different versions of an application which is partly obfuscated and thus the names are different in every version and I'd like to find certain changes. For example, there could be a class like this: namespace ns1 { public class SomeClass1 { public string MyProperty1 { get; set } public void Method1() { // Code } public void Method2() { // Code } } } Then, in another version of the source code, it could look like this: namespace ns183 { public class AnotherClass112 { public string someProperty1 { ge…
