I am trying to read a log file which has key value pair separated by colon (:), but for some key value is having lines and space between. I have to read the DETAILED_DESC : till the end of the file. What would the appropriate way to read.

I am creating "say" command for my bot and it is fine, But when I tag someone in-between content it does not send the remaining message.

For Example:

!say [user mention] take your role asap

but the output is:

[user mention]

Code:

Having made a program which streams PNG images to the browser by means of a multipart/x-mixed-replace Content-Type header, I noticed that only the frame before-last is displayed in the tag, as opposed to the most recently sent one.

This behaviour is very annoying, as I'm only sending updates when the image changes to save on bandwidth, which means that the wrong frame will be on screen while I'm waiting for it to update.

Specifically, I am using Brave Browser (based on chromium), but as I have tried with both "shields" up and down, I assume this problem occurs also in other chromium-based browsers at least.

Searching for the problem yields only one relevant result (and many non-relevant ones) which is this HowToForge thread, with no replies. Likewise, I also thought the issue is to do with buffering, but I made sure to flush the buffer to no avail, much alike to the user in the thread. The user does report that it works on one of their servers though and not the other, which then lead me to believe that it may be to do with a specific HTTP header or something along those lines. My first guess was Content-Length because the browser can tell when the image is complete from that, but it didn't seem to have any effect.

So essentially, my question is: Is there a way to tell the browser to show the most recent multipart/x-mixed-replace and not the one before? And, if this isn't standard behaviour, what could the cause be?

And of course, here's the relevant source code, though I imagine this is more of a general HTTP question than one to do with the code:

Our desktop ERP built in VB.NET is suddenly not showing scrollbars in DataGrid control on Windows 10 after updates - KB5001337, KB5001406 (May 2021)

The space for the scrollbars appears but there are no up and down arrows visible!

Same application is showing the scrollbars in Datagrid control on Windows 7 PCs/ windows 10 without these updates. We have multiple Datagrid controls throughout the application so need to find a fix asap

Windows.forms.Datagrid .NET Framework version 3 was used to build in VS 2010

Have already tried -

1. Settings -> Ease of Access-> Automatically hide scrollbars in Windows (turn off)
2. Tried running the ERP using Windows 7 compatibility mode

I have a Java servlet that generates some arbitrary report file and returns it as a download to the user's browser. The file is written directly to the servlet's output stream, so if it is very large then it can successfully download in chunks. However, sometimes the resulting data is not large enough to get split into chunks, and either the client connection times out, or it runs successfully but the download doesn't appear in the browser's UI until it's 100% done.

This is what my servlet code looks like:

Considering I have the following code:

So, I have the following scenario.

I am working on a system for academical papers. I have several inputs that are for stuff like author name, coauthors, title, type of paper, introduction, objectives and so on. I store all that information in a database. The user has a Preview button which when clicked, generates a Word asynchronously and sends the file location back to the user and that file is afterwards shown to the user in an iframe using Google Doc Viewer.

There's a specific use case where the user/author of the paper can attach a .docx file with a table, or a .jpeg file for a figure. That table/figure has to be included inside the final .docx file.

For the .docx generation process I am using PHPWord.

So up until this point everything works fine, but my issues start when I try to mix everything and put together the .docx file.

Approach Number One

My first approach on doing this was to do everything with PHPWord. I create the file, add the texts where required and in the case of the image just insert the image and after that the figure caption below the image.

Things get tricky though, when I try doing the same thing with the .docx table file. My only option was to get the table XML using this. It did the trick, but the problem I ran into was that when I opened the resulting Word file, the table was there, but had lost all of its styling and had transparent borders. Because of those transparent borders, afterwards when converting it to PDF the borders were ignored and the table info is just scrambled text.

Approach Number Two (current one)

After fighting with Approach Number One and just complicating stuff more, I decided to do something different. Since I already generated one docx file with the main paper information and I needed to add another docx file, I decided to use the DocX Merge Library.

So, what i basically did was I have three generated word files, one for the main paper information, one for the table and one for the table caption (that last one is mainly to not overcomplicated the order of information). Also, that data is not in the table .docx file.

Then I run this:

As the title says, I am having some trouble with AVAssetWriter and memory.

Some notes about my environment/requirements:

• I am NOT using ARC, but if there is a way to simply use it and get it all working I'm all for it. My attempts have not made any difference though. And the environment I will be using this in requires memory to be minimised / released ASAP.
• Objective-C is a requirement
• Memory usage must be as low as possible, the 300mb it takes up now is unstable when testing on my device (iPhone X).

This is the code used when taking the screenshots below https://gist.github.com/jontelang/8f01b895321d761cbb8cda9d7a5be3bd

Most of the things that seem to take up a lot of memory throughout the processing seems to be allocated in the beginning.

So at this point it doesn't seem to me that the issues are with my code. The code that I personally have control over seems to not be an issue, namely loading the images, creating the buffer, releasing it all seems to not be where the memory has a problem. For example if I mark in Instruments the majority of the time after the one above, the memory is stable and none of the memory is kept around.

The only reason for the persistent 5mb is that it is deallocated just after the marking period ends.

I actually started writing this question with the focus being on wether my code was releasing things correctly or not, but now it seems like that is fine. So what are my options now?

• Is there something I can configure within the current code to make the memory requirements smaller?
• Is there simply something wrong with my setup of the writer/input?
• Do I need to use a totally different way of making a video to be able to make this work?

In the documentation of CVPixelBufferCreate Apple states:

If you need to create and release a number of pixel buffers, you should instead use a pixel buffer pool (see CVPixelBufferPool) for efficient reuse of pixel buffer memory.

I have tried with this as well, but I saw no changes in the memory usage. Changing the attributes for the pool didn't seem to have any effect as well, so there is a small possibility that I am not actually using it 100% properly, although from comparing to code online it seems like I am, at least. And the output file works.

The code for that, is here https://gist.github.com/jontelang/41a702d831afd9f9ceeb0f9f5365de03

And here is a slightly different version where I set up the pool in a slightly different way https://gist.github.com/jontelang/c0351337bd496a6c7e0c94293adf881f.

So I looked a bit deeper into a trace, to figure out when/where the majority of the allocations are coming from. Here is an annotated image of that:

The takeaway is:

1. The space is not allocated "with" the AVAssetWriter
2. The 500mb that is held until the end is allocated within 500ms after the processing starts
3. It seems that it is done internally in AVAssetWriter

I have the .trace file uploaded here: https://www.dropbox.com/sh/f3tf0gw8gamu924/AAACrAbleYzbyeoCbC9FQLR6a?dl=0
