There are multiple options on how to configure ArgoCD. A great way is to use a declarative approach, which should be the default Kubernetes-style. Skimming the ArgoCD docs there's a additional configuration section where the possible flags of the ConfigMap
argocd-cmd-params-cm can be found. The flags are described in argocd-cmd-params-cm.yaml. One of them is the flag
I can declare a static byte array in VBA like this, but it appears that the elements are not of type byte....
ANSWERAnswered 2022-Mar-12 at 01:37
ok, probably not the solution you were looking for, but you can convert a string directly to a byte array..
So, for your example, something (crazy) like this will work..
Using Access 365. I would like help building code to achieve the following please, I’m trying to streamline adding images to a record.
I would like to use VBA that on clicking a button will save an image as a .jpg from the clipboard (put there by User using Snip tool) to a subfolder of the database, then pass a relative link to this file to the form. I’d like to be able to attach multiple images’ links to a given record in this manner.
Using the code below (without the AltPrintScreen element) I’ve gotten as far as saving from the clipboard and generating an absolute link, but only as a .bmp. (https://www.access-programmers.co.uk/forums/threads/print-screen-into-image-file.245198/). Grateful for any help getting the rest of the way, or suggestion of an entirely different way of doing it. Cheers!

I've created a solution that does what I want. I've used four Modules I found on various sites and then created a bit of VBA to pull the tasks together in the background.
- Module 1 is the one I posted in the question above. I bypass the AltPrintScreen part of it so it doesn't overwrite the image already in the clipboard.
- Module 2 Converts the BMP created by Modules 1 into a JPG.
- Module 3 Scans a folder and populates an unbound listbox with a list of the files found there.
- Module 4 is used to make the filepaths in the listbox act as hyperlinks to open the images on clicking.
I then created a button on a form that calls the first two Module to create a jpg from the image in the clipboard as follows...
I have created a Reactor Netty HTTPSever which works fine, I wanted to add an delay for each response i.e if I send a request I should get the response after say 10 sec, I need this delay to test something. Below is the code used to create the server...

send() method returns
Mono, so you can invoke the
delay* operators that
Mono provides. The example above can be changed like this (this example below delays headers and sends an empty response body):
I've wrote the following function that reads http response from the server through the socket. I had no problems reading text pages like this page but when I try to read images:
the reading goes on without adding data to the buffer, even though the read returns the correct byte amount.
ANSWERAnswered 2021-Nov-25 at 16:53
I believe that
read_unknown_size is working, but the caller is simply printing out the buffer up until the first NUL character by using
printf("%s", buf) or similar. This is wrong for two reasons:
- If the data read contains a NUL, it will stop outputting too soon.
- If the data read doesn't contain a NUL, it will read beyond the end of the buffer.
The caller needs to output exactly the number of characters in the buffer. However, the caller has no way to determine the how many characters are in the buffer. So, in order to do anything useful with the result of the function, the function needs to return not just the buffer but the number of characters it read.
I'm trying to build a container image that I will later use to update the code inside of a virtual machine. The docker image works fine as I can build and run it inside of my terminal. However, I keep getting an error when I try to deploy it to cloud run: "Cloud Run error: Container failed to start. Failed to start and then listen on the port defined by the PORT environment variable." How can I fix this error?
The build log contains this:...
ANSWERAnswered 2021-Sep-15 at 21:20
When Cloud Run starts your container, a health check is sent to the container. Your container is not responding to the health check. Therefore, Cloud Run determines that your service is failing.
Cloud Run requires that a container provide service/process/program that listens for and responds to HTTP requests.
Your hello.py file only prints a message to stdout. Your program does not start a process to listen for requests.
A very simple example that converts your example into a working program:

something like this, then restart your server for new config to be loaded
I am running a basic Quarkus application on Google Cloud Run.
The default settings use HTTP 1.1 between Cloud Run and the backend container. If I enable http2 then CORS fails because the
Access-Control-Allow-Origin header is mangled and returns the origin and the wildcard together and so is rejected by the browser.
For example when testing my app using the online Swagger UI the response is:
Testing my app locally with curl and h2c does not show the problem. Therefore it seems that Google Cloud Run is doing some mangling of this header.
Is there some config I can set to stop this from happening?...
ANSWERAnswered 2021-Jul-07 at 21:05
I managed to track down the underlying problem in the framework that I was using.
The bug was that the framework was returning duplicate headers. For example:
Trying to use Jetty 10 with HTTP/2 (h2) in Spring Boot 2.5.1 results in a NoSuchMethodError:
java.lang.NoSuchMethodError: 'void org.eclipse.jetty.server.SslConnectionFactory.(org.eclipse.jetty.util.ssl.SslContextFactory, java.lang.String)'
HTTP/2 over TCP (h2c) works fine, as stated here (it still hurts): https://github.com/spring-projects/spring-boot/issues/26979, but adding SSL breaks the startup.
Using Jetty 9.4 instead, it works flawlessly. The thing that puzzles me is that the code seems fine, Spring Boot is passing the right arguments and the method does actually exist in the Jetty class.
Has anyone else experienced this? There doesn't seem to be any issue about this in Github, and I find it rather odd that I'm the first one trying this setup.

This was caused by a bug in Spring Boot 2.5. Thank you for bringing it to our attention. It has been fixed and the fix will be available in Spring Boot 2.5.2.
I have a PHP Web Service that can insert a new row to my database if I hardcode the values in to the SQL query directly. But when I try to do this using variables passed to the PHP script from my Swift function it breaks down. I have add print statements to my Swift so I am confident that the values are being passed to the function correctly and the error must lie in the lines afterwards.
PHP: I have commented the SQL query line out with the hardcoded values - Carrots, but this query does work so I think PHP->SQL is working ok, but Swift->PHP is the problem....

When you get a 500 error, that could be a malformed request. Or it could be a syntax error in the PHP code. Or it could be both.
In this case, it is likely the PHP syntax error, as there is a missing
) at the end of the
prepare call. But it could also be the former (as the Swift code is not percent encoding the
When you get 500 codes, look at the end of the server’s
error_log (generally in the directory where your PHP files are located). In this case, I looked and it said:
[19-Jun-2021 13:45:00 America/Boise] PHP Parse error: syntax error, unexpected ';', expecting ')' in /.../insert.php on line 103
That is a syntax error in the PHP that must be fixed.
That having been said, there is a problem in the Swift code, too. It is manually building the body of the HTTP request. One should percent encode the values in the body of the request. There are libraries, like Alamofire, will automatically percent encode
application/x-www-urlencoded requests (which this is). If writing one’s own Swift code to build the request, you want to percent encode them manually as outlined in HTTP Request in Swift with POST method.
Note, if (a) your request includes characters that need percent encoding (e.g., spaces or certain symbols); and (b) you fail to do so, then that, too, can result in 500 error from the web server. Again, the
error_log file would tell you what went wrong, but percent-encoding the body of the
URLRequest is important if the values might include any reserved characters.
That having been said, there are a few other observations:
Your code, as provided in the question, does not quite make sense. You are storing the result of the
preparecall (which is a “statement”) into the variable called
$sql. (As an aside, because it is a statement, naming that variable
$statementwould make more sense.) You later supply that to
queryis expecting a SQL string, not a “statement” as returned by
prepare. You should, instead, just check the return values from
execute. Do not call
queryafter having prepared, bound, an executed the statement.
bind_paramdo not match up with the default values that you have given your five variables with the content of the
$_POST. You might want to double check that.
Not directly related to the question at hand, but I would make a few suggestions. Namely, when writing a web service, like this, I might suggest suggest the following:
Set the HTTP status code (e.g.
http_response_code(201)on successful insert,
http_response_code(422)on insertion failure).
I would also return results as JSON (e.g. use PHP associative array for the results and then use
json_encodeto build the response to be echo’ed by the PHP), rather than text string. Then the client app can easily parse the responses.
I would set the
header("Content-Type: application/json")) so that the client app knows how to parse the response.
A very minor/subtle observation: In the PHP, there is a space before the initial
. You don’t want any characters before the PHP starts. It can cause very subtle problems. (Hopefully it is just a typo introduced during the preparation of the question, but just a word of caution.)
