You will have to manually setup any relevant event handlers and properties again for the TComport component.
-
I edited the .pas file and also the .dfm and the form opened, but when I added the new component to the form, the properties were not automatically rewritten. How can I make it automatically rewrite? It still has the old properties in my .pas file
-
Well you may need to manually edit the dfm file and pas file in notepad or some other text editor. Delete the reference to TComport the the form declaration in the pas file. Then try and open the dfm file and delete the TComport section from the DFM file. I think the DFM file is highly likely to be in a binary format though so you will have to use the convert.exe which is in the bin folder of your version of Delphi to convert it to text before you edit it.
-
Thanks for the comment, but it didn't work.(The form does not open after the error) After ignoring it, the following error appears: Error creating form: Cannot assign a nil to a TComParity.
-
My guess would be to make a backup of the .pas file and .dfm, select ignore on all those errors. Once loaded delete the comport component from the form (if it still exists). Then add backthe TComPort component. This will make the component have all the default values for the latest version of the component

Dear authors, dear community! I need help with ComPort component. It is used in Delphi 7 application to control 2 servomotors and everything works qiute stable until once it hangs. It may happen once per day or 2 times per hour. Addtitional debug output in my code revealed that it happens here: log('something'); result := ComPort.Read(@msg[from], len); log('something'); the first log line tells the function was called expecting to receive 3 bytes of data, the second log line never happens thus hang...

Hi, I use comport411f.zip in my application written in Delphi 5 or Delphi XE4 with some my additions/corrections (USB/RS232 arrive/remove, EnumComPorts, TComThread, ...).

Hi, I would like to ask you not to look at the problem I am solving now. Maybe you have already met something similar and you will be able to advise me. 2 different applications have been running on Windows XP for many years and also on - without any problems. 1.) When switching to Windows 10, Windows 10 will randomly terminate the application after any time without any error message. Both applications are on different PCs with different motherboards and with Windows 10 professional. 2.) Applications...

Chris Landon posted a comment on discussion Open Discussion
You were correct. The comport component from Async (APRO) does work with USB virtual comports. I didn't think it did for two reasons. First, I have been through much of the manual and it says absolutely nothing about USB or virtual comports. And also, I had tried it and didn't see that it could work with USB. So what I did is I put a ApdComPort object on a form, added a button, and made the button open a comport. This is what I didn't do before. Now I ran it and hit open. open brings up a dialog...

It should not make a difference whether USB is used, or not. All software types work on an operating system level, and cannot differentiate between USB comports and other comports. Lars.

Hello, I have been using the free download of Comport Library by Dejan Crnila for a couple of years, in RAD Studio 10.2 (Delphi). It works well for me. I have upgraded to RAD Studio 11 and want to buy the full latest version when it is updated for RAD Studio 11. I would like it to work with Windows and Linux. I am confused by the several different ComPort components I have seen advertised. Some have similar but different version numbers. I don’t know if these are the same or are completely different...

I unzipped the zip-file and opened the example-codes *.dpr-file into Delphi 10.4 CE Delphi was complaining about a LED-component missing. Guys why do you feel the need to add some other components to example-codes that complicate things? Why don't you provide all components that are needed to make your examples run?

Hi Guys, been using this since Delphi 6! Delphi 10.3 Latest TComport version Data exchange works fine up to 128000, I guess where most people top out. The UART in question (CH340) supports up to 2Mbit. Have wound up to 2Mbit with Putty and data exchange is fine. Anything above 128000 and there seems to be an issue. I can see my device gets the data but it looks like its getting junk. Again Putty I can wind up to full speed just fine. I had assumed it was an issue with using brCustom but using br256000...

These are steps I took: - Added ". .\source" dir to lib path - a) Opened .groupproj tried to build -> got error - b) Tried to open .dpk file and compile -> got error - and so many other ways and still no success. If anybody could show me the steps I should take, I'll be greatly appreciated
