detour | Node.js / Express.js Routing | Runtime Evironment library

My DLL gets injected into a program and then hooks to connect, send, recv and closesocket functions using Detours. The point is to stop the program from connecting to some server and instead communicate with my DLL directly.

My recv function uses an infinite loop, just waiting for any data to send to the program. When closesocket is called that loop is broken and everything works fine.

But there's one program written in C# that just hangs when I close it. Its error log says:

SocketException: A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket using a sendto call) no address was supplied.

at System.Net.Sockets.Socket.Disconnect (Boolean reuseSocket) [0x00000] in :0

The exception is expected since the socket never connects to anything. But is there any workaround for this? What does System.Net.Sockets.Socket.Disconnect call under the hood? What other function do I need to hook to detect that?

I've tried hooking to shutdown, setsockopt, WSACancelBlockingCall, WSACleanup, WSASend, WSASendDisconnect, WSASendMsg, WSASendTo, WSARecv, WSARecvDisconnect and WSARecvFrom. None of them get called.

I have a workflow that requires me to hand a file around my team and each of my team members needs to do something with this document. They have to do it in a certain order and one after another.

The current solution is that I send an email to the first person with this file and wait until I receive the document back. Then I send the received document to the next person and so on...

I already looked at all the connectors, especially the email with options from the outlook connector and the Approvals Connector look promising.

Getting the file into the workflow and attaching it to an email is easy and I am stuck for quite some hours now on how to get the received file back into the workflow. I should add that in the ideal case the file goes directly back into the workflow without taking the detour through my mailbox.

The is a bunch of commercial solutions out there, e.g. Adobe Sign, but i would really like to solve this without having to upload my files to some other service and rely on an other company (other than microsoft obviously).

I would really appreciate any suggestions on how one could solve this task!

Thanks a lot.

I am trying to use the detours library in a visual studio empty windows project. I cloned the repository (https://github.com/microsoft/Detours), I added the include directory into Project Properties / C/C++ / Additional Include Directories, and I added the lib.X86 directory into Project Properties / Linker / Additional Library Directories. I get no errors visible on the file, but when I build I get

I've tried to add another observable to my merge, so starting from the correct

I have a cartoon of an antique "detour" sign that has cataphote reflectors embedded in the letters. I want the reflectors to brighten as the image is hovered. That's easily done, I know, simply by swapping out a version of the image with the reflectors darkened with an image of them brightened on hover (per the markup below). However, doing it this way makes the reflectors appear to blink on or off. I want them to get increasingly bright as the cursor nears the center of the image and, of course, dim as the cursor moves away from it, as would occur in real life. (If your headlights beamed at the reflectors at an oblique angle, the light they reflect back would be dimmer than if your headlights hit them straight on.)

My thought is just to increase the opacity of the brightened version of the image in response to the position of the hovering cursor. So, what I need (I think) is a script that detects the cursor position and increases or decreases the opacity accordingly: opacity: 0; at the edge and opacity: 1; at the center. Probably not too challenging for someone adept in javascript/jquery. I've hunted around for a script that does that or something very close to it but haven't been able to locate one that is close enough for me to modify.

I have an additional issue in that in Firefox, at least, the hover image "flicks" the first time it is invoked. I've tried all of the preloading suggestions I could find here on stackoerflow but none of them work. I found that a sprite solved the flicking problem, but wasn't sure how that would work with the way I want the image to animate. Presuming non-sprite images are the way to go maybe if the script invokes the "bright" version of the image at an initial opacity of 0 as the cursor crosses the threshhold, it will also hide the loading "flick...?" Just a guess. Alternatively, I could redesign the hovered version so that it is just the reflectors if that would solve everything else.

Finally, as you can see, the sign is a button that returns a random page. Assuming what I need to solve this problem is a script, can I run both scripts off of the same id (#detour) or should this script use a class name instead? (I am clearly an example of a little knowledge being a dangerous thing.)

Anyway, here's what I've got.

I am having trouble setting up a GStreamer pipeline to forward a video stream over UDP via OpenCV. I have a laptop, and an AGX Xavier connected to the same network. The idea is to forward the webcam video feed to AGX which will do some OpenCV optical flow estimation on the GPU (in Python), draw flow vectors on the original image and send it back to my laptop. Up until now, I can configure two pipelines. As a minimum example, I have made two bash scripts and a Python script that ideally would function as pass-through over OpenCV's VideoCapture and VideoWriter objects.

I have a dataframe with speech data in column Turn:

Version: Delphi Berlin 10.1

I am encountering problems, in what I consider to be a vcl theme bug, that when applying a vcl style theme to the application, messages using TApplication.MessageBox are limited to 256 characters.

TApplication.MessageBox with 298 characters of text WITHOUT the VCL theme applied. All text is displayed correctly. Link: without VCL Style Theme

TApplication.MessageBox with 298 characters text WITH the VCL theme applied. The text is limited to 256 characters and the rest is cut. Link: with any VCL Style Theme (Windows10 example)

I have already analyzed the TCustomStyle class of Vcl.Styles.pas but I have not found how to solve this unpleasant situation, so I would like your help.

EDIT:

Following the information that Andreas Rejbrand passed, it was possible to identify that it was a limitation in the buffer size of the GetText of TStyleHook that was limited to the array of [0..256] of char. With this information I created a detour for a new method where I increased the buffer size to array of [0..1023] of char which solved my problem.

Note: Unfortunately updating the IDE (which would solve the problem) to a newer version is not possible at this time.

The function get_from_string below basically casts a string to a variable by creating a stringstream from the string and writing that to (a pointer of) the variable. Afterwards, it returns whether that was successful or not. If the variable is an enum class, it goes a little detour over the enum class' underlying_type and uses a static_cast to achieve the same effect.

The code below works perfectly, but I can't manage to get rid of the two get_from_string_helper_structs. Can I solve this without any helper structs and only with functions?
