![]() ![]() It turns out there were errors in the anycodings_enumerate example code, and anycodings_enumerate possibly errors in the JVCL code. I was able to get some more specific anycodings_enumerate suggestions by asking the question a anycodings_enumerate different way with different tags. anycodings_delphi The uses statement is " windows,ĬomPortStringList := SetupEnumAvailableComPorts įor Index := 0 to ComPortStringList.Count - 1 do I'm testing with a simple console program. anycodings_delphi Is anyone familiar with the changes to anycodings_delphi setupapi that could cause these problems? I get the anycodings_delphi error "Types of actual and formal parameters anycodings_delphi must be identical" on the parameters anycodings_delphi and Delphi3000 site says the code was anycodings_delphi written in 2004 and is intended for Delphi anycodings_delphi 7, so I'm not sure why it doesn't work with anycodings_delphi Delphi 7 now, unless setupapi has changed. In the call to function anycodings_delphi SetupDiGetDeviceRegistryProperty, I tried using the setupapi unit from the anycodings_delphi current anycodings_delphi JVCL(JVC元40CompleteJCL221-Build3845), but anycodings_delphi it doesn't seem to be compatible with Delphi anycodings_delphi 7. I found this example code, but it is written anycodings_delphi for an older version of the setupapi unit anycodings_delphi (the original link to anycodings_delphi doesn't work of course). The ports may dynamically change anycodings_delphi as USB-serial devices are connected and anycodings_delphi disconnected at runtime.īased on the possible methods described in anycodings_delphi this question, I am attempting to use the anycodings_delphi SetupDiGetClassDevs method. Procedure TMainForm.I'm trying to enumerate "friendly names" for anycodings_delphi COM ports. varįunction ParseAndCheckMessage(const parseS: AnsiString) : Integer If your message is constructed in another way, I'm sure you can figure out how to adapt the code. Here is an example where the message start is identified with a special character and the end of the message is identified with another character. ![]() When you get the final character in your message string, handle the message. You have to buffer all incoming characters in a global buffer. So when you expect the message to be transferred, you get what the OS is giving you. ![]() This information is then simply popped up to your level. Normally the thread that is responsible to gather the bytes from the port is informed by the OS that one or more bytes are ready to be processed. Most com-port components do not have a clue when to report back to the owner. ![]()
