Category:Programming Share this conversation Expert: John replied4 years ago. Hello,I am John and I will ty to help you.What is your actual problem ?Are you just trying to access the Registry ? Ask Your Own Programming Question Customer: replied4 years ago. No, I cn access the registry. This problem is very specific and some knowledge about comm ports related to the Windows 7 registry will be required. Specifically, I have a java program using a comm api that is getting an error when trying to get comm port information. The error is: Error 2 opening registry key HARDWARE\DEVICEMAP\SERIALCOMMAnd the error is valid because that entry is not in the registry as far as I can see via regedit.

What information do you need? Expert: Jinsmn replied4 years ago. Hi, welcome to justanswer. I am Jins here to assist you. Securtity controlls of Windows 7 will not allow you to access some sensitive registry and system file locations. You need to activate the builtin administrator account of windows 7 to get access on such parts.First you’ll need to open a command prompt in administrator mode by right-clicking and choosing “Run as administrator” (Type cmd in the start menu search text box.

I encountered a problem on a Windows XP/SP3 machine with a program called "3M Clean Trace Data Trending Software" (v5.01). The application interfaces with a USB serial (COM) device and, unless http://www.justanswer.com/computer-programming/5wcw6-need-help-windows-7-specifically-comm-ports.html the user is made a local administrator, the following error messages are encountered: Trend Analysis Error opening key. (OK) ...followed by... 229: COM Port Failure A communications Port cannot be detected on this computer (OK) According to the 3M technical bulletin (TB.066.00) the fix is to http://www.myitforum.com/forums/quotHKLM92HARDWARE92DEVICEMAP92SERIALCOMMquot-Permissions-m209469.aspx allow "Everyone" "Full Control" permissions on the following registry key: HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\SERIALCOMM This does fix the problem, as long as the user does not reboot the computer. As soon as the computer is rebooted, the operating system recreates this key and removes any previously configured custom permissions--even if the permissions are changed on the parent key, "DEVICEMAP", and set to "Replace permission entries on all child objects". In a web search, there appear to be various other applications encountering similar problems with permissions on this key because of the way Windows "rebuilds" this key on reboot. Although a bit messy (and most likely not supported by 3M--certainly not approved), this is the way I resolved this issue without granting users the local administrator privilege... 1.) Create the folder "C:\SerialComm" 2.) Create a text file named "serialcomm.txt" inside the "C:\SerialComm" folder containing the following line of text: HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\SERIAL
I run the program CommTest.java. One solution that i found on internet was to modify registry key for HARDWARE\DEVICEMAP \SERIALCOMM. But I dont have SERIALCOMM under HARDWARE/DEVICEMAP. Does that mean my laptop has no serial port? If this is the case what http://osdir.com/ml/smslib/2010-01/msg00189.html should i do to run the program (though i have a usb port)? -- You received this message because you are subscribed to the Google Groups "SMSLib for Java User Group" group.
