Performant hooking of OpenGL to draw an overlay - problems with multiple contexts

人走茶凉 提交于 2019-12-04 05:09:26
问题 Like others in previous questions, I'm trying to hook an arbitrary OpenGL application to draw an overlay onto it. I've hooked SwapBuffers and created a separate context on first call to draw into. See this SO question/answer for the general idea. There are two big problems I'm hitting. First, the calls to wglMakeCurrent to set/restore the context before/after drawing absolutely destroy performance. Is this expected? I need to look more into using _ARB_context_flush_control as mentioned by

SVN client side hook

只愿长相守 提交于 2019-12-04 05:00:33
Does SVN have client-side hook support like in TortoiseSVN ? I need a hook so that when I send a commit the browser opens a specific url. No. Client-side hooks are a TortoiseSVN-specific feature. Use an alias for SVN i.e. a python script that validates your inputs then forwards the call on to the real SVN. It might take a bit of work to get advanced functionality though, such as understanding changelist content, but there's libraries which can help and if you hunt around the internet someone has probably make something similar to what you want already. http://pysvn.tigris.org/ http://top-frog

Change the key being pressed with C#

断了今生、忘了曾经 提交于 2019-12-04 04:20:48
Hey, I'm trying to write a program in C# that will track the pressing of certain keys (using a keyboard hook), and send different ones instead. For instance, when I press the A key it will instead send the Q key. I used http://www.codeproject.com/KB/cs/CSLLKeyboardHook.aspx this for my hooks and tried to use the SendKeys function, but I get an exception about the garbage collector destroying some object inside the hook class. First you need to hook up the keys. With this class you can register a global shortcut, I'm skipping the explanation, but you can read it here . public class KeyboardHook

How to use ZwQueryInformationProcess to get ProcessImageFileName in a kernel driver?

三世轮回 提交于 2019-12-04 02:48:28
I'm writing a simple kernel driver for my application (think of a very simple anti-malware application.) I've hooked ZwOpenFile() and used PsGetCurrentProcess() to get a handle to the caller process. It returns a PEPROCESS structure: PEPROCESS proc = PsGetCurrentProcess(); I'm using ZwQueryInformationProcess() to get the PID and ImageFileName : DbgPrint("ZwOpenFile Called...\n"); DbgPrint("PID: %d\n", PsGetProcessId(proc)); DbgPrint("ImageFileName: %.16s\n", PsGetProcessImageFileName(proc)); and trying to get the process FullPath this way (but I get BSOD): WCHAR strBuffer[260]; UNICODE_STRING

WooCommerce Product Template

早过忘川 提交于 2019-12-04 02:22:06
问题 I would like to move my thumbnails on my product template in WooCommerce, to position them beside the big product picture, underneath the price and add to cart buttons. (As standard, they are positioned directly underneath the big product picture) The template seems to be using hooks though, and I haven't tried using that before. I have found a 'content-single-product.php' that seems to do the stuff, but I can't find anything about thumbnails in that file. Can someone point me in the right

php hook core functions

大憨熊 提交于 2019-12-04 01:54:45
问题 I want to hook before execution / or replace standart core functions, for example i im going to prevent both include and require accesa to any scripts. Is any way to make it without any extra .dll's? Or another case is_array($myarr); i would be to hook at array($myarr) === $myarr; ( looks like it is faster ) to avoid creating extra classes and functions. Ps and one more question : how to prevent all php execution after some moment? I have html templates with php parts <?=$myvar?> i want to

How do I create a 'route' in wordpress?

做~自己de王妃 提交于 2019-12-04 00:35:44
For my own sanity I'm trying to create a route for an ajax api that looks something like: /api/<action> I'd like wordpress to handle this route and delegate to the proper action with do_action . Does wordpress give me a hook to implement this? Where's a good spot? You have to use add_rewrite_rule Something like: add_action('init', 'theme_functionality_urls'); function theme_functionality_urls() { /* Order section by fb likes */ add_rewrite_rule( '^tus-fotos/mas-votadas/page/(\d)?', 'index.php?post_type=usercontent&orderby=fb_likes&paged=$matches[1]', 'top' ); add_rewrite_rule( '^tus-fotos/mas

How to create a trampoline function for hook

岁酱吖の 提交于 2019-12-04 00:28:05
I'm interested in hooking and I decided to see if I could hook some functions. I wasn't interested in using a library like detours because I want to have the experience of doing it on my own. With some sources I found on the internet, I was able to create the code below. It's basic, but it works alright. However when hooking functions that are called by multiple threads it proves to be extremely unstable. If two calls are made at nearly the same time, it'll crash. After some research I think I need to create a trampoline function. After looking for hours all I was not able to find anything

Hooking an existing method in Java

故事扮演 提交于 2019-12-04 00:14:12
I want to hook the method System.out.print in Java and have the ability to read/change the variables used in the method before the part of the method is called that actually adds the string to whatever the output stream is. In C++ I would just detour the function, or set an int3 instruction so I could access the registers but in java I have no idea how to accomplish something similar. sbridges You can rewrite the byte code of the methods, and in the process capture/change the local variables. It is not trivial. See some notes here . Maybe what you really want is a java debugger? You can
