The IBKR TWS (Trader Workstation) is a tool for managing stock orders in the stock market, by Interactive Brokers. They provide an API to automate orders, like placing orders, cancelling orders, and more.

I'm creating a program to handle executed orders in my Trader Workstation using the Interactive Brokers Java API.

I'm having trouble detecting when an order fills.

The documentation describes that the execDetails callback (which is an EWrapper method, see code below) is invoked when an order is filled, but I tried using that and the execDetails callback was never invoked (I tested this by logging the reqid int in that callback, and I never got any log).

I have also researched about the completedOrder callback, which I'm not sure if that's the callback that will be invoked when an order is filled, because I tested both callbacks with a simple log, and nothing was outputting in the console.

I don't understand the reqExecutions function and whether I need that. I have already read the documentation on this callback, and I don't understand what I'm doing wrong. I want to know I how can detect when an order fills, or executes in the TWS using their API.

Here is my current code:

I am following an OpenGL tutorial from https://learnopengl.com/ (specifically https://learnopengl.com/Advanced-OpenGL/Depth-testing) and I have many errors to do with stbi. Error Log image here (Below I have also attached the complete Output tab). I have added the "#define STB_IMAGE_IMPLEMENTATION" at the top of the main.cpp file (and not in a header). If I don't use any stb_image functionalities, the project compiles and runs. I have had projects where stb_image worked fine, but all those projects that worked were x86 (or 32-bit). It seems that I can not get stb_image with x64 (or 64-bit). I know that x64 itself works since other projects without stb_image that were x64 have compiled. I have also looked back to where I downloaded the header file for stb_image and there was no option for x64 vs x86 as there was only one universal option. Here is an image of how the files are organized: File hierarchy. I will also include my main.cpp file but if you want to see a specific file let me know. I am very new to c++ since I come from java and python so any help is appreciated.

Hello I am beginner in Android NDK programming and I need some help getting freetype library to work with my project. I've been trying for 3 hours straight to somehow import freetype to my Android Studio project. I searched on the internet and could not find any solution that was working. I downloaded the library and put it in my cpp folder of the project.But I don't know how to include freetype. Any help would be appreaciated!

This is how my CMakeLists.txt look and for the files that I have added it works for them:

I´m working on a Vulkan application and want to implement a "flying camera" which can move around anywhere freely.

I placed a cube in the middle of the scene that I can fly around. The camera position works perfectly but the rotation acts weirdly as soon as I move around the cube. When I´m on the opposite side of the cube the UP and DOWN directions that I give via my mouse are inverted and when I´m on either side of the cube they just don´t work at all. Anywhere between that it just does weird circles. Note that this only affects up and down movements not left or right.

Here is a demonstration of how it looks for me where I only move my mouse up and down in this order on every side of the cube (except when moving around it) I apologize for the bad frame rate, i had to convert it to gif and lower the quality: https://imgur.com/HxknkQV

Quick explanation of the video: Firstly, while it might have looked like I moved my mouse left and right while not moving looking at the sides, I didn´t. I only went up and down every time except for when I moved into the positions. The other thing is that while for the opposite site of the cube it might have looked like the rotation worked, it was actually inverted.

This is the code for my Camera:

I'm trying to use a compute shader to do three-dimensional physical simulations but having trouble storing anything into my 3D texture. My shaders compile successfully but when reading back any value from the 3D texture I get a zero vector. I haven't used compute shaders before either so I'm not sure if I'm even distributing the work load properly in order to achieve what I want.

I've isolated the problem in a small example here. Basically the compute.glsl shader has a uniform image3D and uses imageStore to write a vec4(1,1,0,1) into gl_WorkGroupID. In C++ I create a 100x100x100 3D texture and bind it to the shader's uniform, then I call glDispatchCompute(100,100,100) - to my knowledge, this will create 1,000,000 jobs/shader invocations, one for each coordinate in the texture. In my view.glsl fragment shader I read the value of a random coordinate (in this case (3,5,7)) and output that. I use this shade a cube object.

Everything I've tried results in a black cube being output:

Here's my code (I've been following along with learnopengl.com so it's mostly the same boiler plate stuff except I extended the shader class to handle compute shaders):

I had no error. Always refresh cache and local memory.

I have a list of pandas data frames that I got applying the groupby function and I want to add to them a new column with the frequency of each kmer. I did that with a loop but I got a message warning that I need to use df.loc[index, col_names]. Here it is a link to one example of the csv file: https://drive.google.com/file/d/17vYbIEza7l-1mFnavGGO1QjCjPdhxG7C/view?usp=sharing

Here is my code snippet -

I don't have very much experience with OpenGL, GLFW, or GLEW so my troubleshooting ability with these libraries is slim to none. I have managed to render a triangle ([-1, -1, 0], [1, -1, 0], [0, 1, 0]) but when using the vertex attribute coordinates for a cube, along with color attributes it seems to not render. There could be a lot wrong with my code, the shaders, and my matrix operations. I wish I had a clearer understanding of what I'm doing so I could give a more descriptive account of my error. Currently the above code only renders the window. I followed https://learnopengl.com/ initially and got the first tutorials working, the following code is my "testing" file where I've attempted to reimplement some of the elements myself. There are lots of copy pasted portions that may be shared with that tutorial if it helps at all.

Any insight or suggestions would be appreciated very much.
