问题 I've been trying to figure out how to divide the contents of a TkInter entry box with a number (a float, to be precise). I looked it up on Google, and I found nothing that answered my question, other than doing .get() for getting a number from a entry. I want to have a number already there (or have a static variable) that I can divide to get the results I need. Any help would be appreciated! Thanks a billion!! :D P.S. Here's the website results I saw before I posted this question: Results of

问题 I have a dataset, made up of a mask file, and a data file. the mask file tells the decoder whether there are 8 bits per field present, or 4, for the current offset of the datafile. I need to shift the data out according to the mask, and write the decoded file, with all 8 bits per field. I'm trying to accomplish this in C. void shift_4bits_left(unsigned char* array, unsigned short size) { int i; unsigned char shifted = 0x00; unsigned char overflow = (0xF0 & array[0]) >> 4; for (i = (size - 1);

问题 I am trying to run Shopizer in Intellij, but getting the following exception. But in cmd is working absolutely fine. Can somebody please help me? Thanks in advance. Application run failed org.springframework.beans.factory.BeanDefinitionStoreException: Failed to parse configuration class [com.salesmanager.shop.application.ShopApplication]; nested exception is java.lang.IllegalStateException: Failed to introspect annotated methods on class org.springframework.boot.web.servlet.support

问题 I am using Rotativa to generate a pdf of my view. on my local computer this works. On my online server, it says cannot locate file or directory. It is probably a permission problem. Any idea how to fix it? Thanx in advance 回答1: Rotativa uses wkhtmltopdf at its' core, which starting from >0.12.0.0 relies on distributable VC++ lib (msvcp120.dll) You may need to download the installer from here rather than just copy dll over to the server http://wkhtmltopdf.org/downloads.html Simple test if

问题 This is one of those "pretty sure we found the answer, but hoping we're wrong" questions. We are looking at a steganography problem and it's not pretty. Situation: We have a series of images. We want to mark them (watermark) so the watermarks survive a series of conditions. The kicker is, we are using a lossfull format, JPG, rather than lossless such as PNG. Our watermarks need to survive screenshotting and, furthermore, need to be invisible to the naked eye. Finally, they need contain at

问题 I wanted to set QCullFace to FrontAndBack and that is why I wrote this: from PySide2.Qt3DRender import Qt3DRender cull_face = Qt3DRender.QCullFace() cull_face.setMode(Qt3DRender.QCullFace.FrontAndBack) render_pass = Qt3DRender.QRenderPass() render_pass.addRenderState(cull_face) The code above should set CullFace globally. But it does not. What did I do wrong? 回答1: I assume that the python binding does not change how Qt works in C++. So you probably have a Qt3DWindow somewhere (unless you

问题 I have a script below that gives the closest 2 values to a given sum. It also iterates through a list of given sums and after each iteration removes the numbers that have already been used. I need to modify this script so that it produces a necessary amount of values closest to each sum, rather than 2. The script needs to accept float values and cannot re-use values. Effectively it needs to pick the most efficient set closest to target, update the set to remove values used, then move on to

问题 I'm attempting to sort this JSON object: JSONObject = { "command": [{ "geobox": [...], "jobName": "...", "keywords": ["..."], "users": ["..."] }, { "geobox": [...], "jobName": "...", "keywords": ["...", "..."], "users": ["...", "...", "..."] }], "type": "..." } It has "command" which is an array of nested json objects and "type" which I don't really care about. I want it to sort the array of nested json objects in "command" in alphabetical order based on the jobName value. I tried something

问题 I'm using Jmeter to test multiple microservice. The basic idea is to test a circuit breaker in a microservice environment. Right now, I'm using two threadgroups, a master and slave remote concept. One thread group creates uses 100 iterations and 1000 thread and creates load against a front-end service, which sends request to a backend service. The other group probes the backend service with 100 iterations but 1 thread. If I’m not wrong the second threadgroup finishes way more early than the
