I cannot sign the bin\Debug\Mainpaint.exe - visual-studio-2019

When I am trying to build my project, it failed and this message occurs.
Can you please help me? So I can rebuild my project again.

It looks like you don't use a codesigning certificate. When your certificate only supports digital signatures, it won‘t work. How do you created the certificate?

iOS certification generation with Codename One

I am trying to generate the required certificates to build Apple App, but I get a runtime error while adding a new device via the certificate wizard.
The error reads (RuntimeError) Please login using Spaceship::Portal.login('user','password')
Before trying to generate a certificate I first connected successfully to itunes connect with my credentials. The error seems to be related to Fastlane presumably used internally by CodenameOne to generate the certificate.
Moreover I also tried to remove one character in the UDID and I got the same error which is estonishing. However the UDID has been double checked with someone who dictated it to me. So the UDID is a 1-to-1 copy of the one shown in itunes.
Why do I get this error message and what can be done to remove it and be able to add the new device ?
Please note : My setup involves codenameone running under Eclipse Mars under Linux 64.
Any help appreciated!
Thanks for reporting this. It should now be fixed. Please give it another try.

Revoking the APNS certificate

In my app i am using APNS. I've made certificates but i am confuse to use.
I am getting the following error.
Warning: stream_socket_client(): SSL operation failed with code 1. OpenSSL Error messages:
error:14094414:SSL routines:SSL3_READ_BYTES:sslv3 alert certificate revoked
I want to delete the certificates and app id and want to generate new ones. My app is not ready for app store now. Can i do this? Or it will create problem for me. Please help me.
If possible please guide me how can i do this smoothly. Thanks in advance.
There should be no problems deleting certificates and generating new ones. You are not limited to just one certificate per account. In fact, you should delete your push certificates from the Apple developer member center and start fresh if you aren't thoroughly familiar with how push certificates work.
The simplest tutorial I know off of the top of my head is here. Go there and follow steps 1 - 4. Another good tutorial is here. While that tutorial is for iOS 6, the steps for generating a fresh certificate are identical for iOS 7.
This will help you get rid of all errors. You will then have to re-upload certificates to your push notifications provider.

"Application failed codesign verifications" Phonegap build app failed to upload to App Store

Ive developed an app using Phonegap. I could build the app for testing using development certificate. And the app works fine.
Now i want to upload the app to app store. But im getting an error saying
"Application fialed codesign verification. The signature was failed, contains disallowed entitlements, or it was not signed with an iPhone Certificate."
After googling lots of time i found the solution. Refer the link for more details - >Click here
One thing to note is that please also make sure to export the .p12 by selecting the certificate associated with the key and not the key. (this ensures we have the correct common name and a valid certificate)
This was the root of problem. It might help someone someday.

No ios development certificate found and No unexpired provisioning profiles found

Tonight I decided to submit my new app to the AppStore, I admit - I was shocked of how horrifyingly
complicated and ridiculously confusing this process is. I managed to submit all the information in iTunes Connect and proceeded to Archive my Application, I did that but then all hell broke loose .. I tried to verify my App but received the error "no development cert. .. contact the admin" well, I am the admin of my account and this certificate is active and installed.
My next steps were to uninstall the Dev and Distribution Profiles&Certificates on my Mac and install them again ... now, after this - it was event impossible to archive my app. I get the following errors
in Xcode: No unexpired provisioning profiles found , and the Organizer: Code Signing error - No ios development certificate found.
I hope that someone can give me any guidelines of how to solve this problem, This problem is really weird - all my certificates are active, and i do have Dev Certificate which could be seen from these screens:
I will go with you step by step:
1- first send me this information marked in the attached image below
2- Then send me the info marked in red here too.
I would ask you to do something after that.
It would be extremely helpful when you do 'figure out' the solution to your problem that you share what you figured out rather than just 'i figured out the connection between these bundle IDs'. I know it isn't the first thought when you do solve your problem, but you could help someone else solve the same problem.

iOS:Code Sign error,Certificate identity appears more than once in the keychain

I've got stuck in this error ->
" Certificate identity 'iPhone Developer:XXXXX' appears more than once
in the keychain. The codesign tool requires there only be one".
I've removed the old certificate and build a new one,but i am still getting this error again and again.I dont see any duplicated certificate.Please suggest any way to resolve this.
Suggestions will be appreciated..
Thanks in advance.
Try restarting your machine. I had this happen to me once a long time ago and if I recall, restarting the machine reinitialized my keychain so it then only saw one cert.
