[DUG] Access Violation
Not sure where to go with this. I'm sending 3 bytes of data at 38400 baud every 500 ms. If I speed up the rate to every 250 ms I get Access Violation at address 004934CA in Mmodule Dyno.exe' Write address 00F2 Code if SerialPortNG.NextClusterSize = 0 then begin sRaw:=SerialPortNG.ReadNextClusterAsString; for i:=1 to length(sRaw) do try iData[i]:= byte(sRaw[i]) except end; I don't know what I'm looking for.

Re: [DUG] Access Violation
Wallace I am not sure what SerialPortNG does exactly (are you using it as a sniffer?) but maybe you could look at an alternative such as AsyncPro (was Turbopower but now open source) or Async32 (TMSsoftware - costs) or TComport (free). I have used all these at some time or other with no issues.

Re: [DUG] Access Violation
One thought, maybe do something like: If length(sRaw) 0 then for i:=1 to length(sRaw) do try iData[i]:= byte(sRaw[i]) except end; This will only do the for loop if sRaw is not empty. Just a thought. I do agree with Paul, Async Pro is very good. I have used it for YEARS and its very reliable. If you want to try it out, its on sourceforge now. We actually bought them before they went open source L Jeremy From: delphi-boun...@delphi.org.nz [mailto:delphi-boun...@delphi.org.nz] On Behalf Of Marshland Engineering Sent: Sunday, 14 August 2011 21:57 To: delphi@delphi.org.nz Subject: [DUG] Access Violation Not sure where to go with this.

[DUG]: Access Violation - Help please.
OK, getting really sick of this now... (Happens multiple times a day) Error Access violation at address 0D34C6FE in module 'bordbk50.dll'. Read of address 001D8000. (the numbers may differ) This occurs when running any app from D5.01 at random. Occurs on Win2000 Pro and Windows ME. Afterwards, I cannot close the app (which is not responding), trying to force it closed causes D5 to say: "This program cannot be closed. If it is being debugged, please resume it or close the debugger first." I then have to KILL D5 to get out of it. Any ideas please Dave. --- New Zealand Delphi Users group - Delphi List - [EMAIL PROTECTED] Website: http://www.delphi.org.nz To UnSub, send email to: [EMAIL PROTECTED] with body of "unsubscribe delphi"
RE: [DUG]: Access Violation - Help please.
I found a major cause of this problem was the debug options. Make sure you do not have "windows messages" checked for the event log window. Once I cleared this the problem went away.

Thanks, the windows messages check box seems to have done the trick.

I'm assuming that all three patches are installed on Delphi as these fixed a healthy number of these less than desirable surprises... One possiblity is the structure of the DPR code if altered in particular ways (mostly around nesting in tr blocks and with clauses) seemed to cause problems when the IDE manipulated the DPR (which I wish it didn't)... The patches all seem to have fixed these however (apart from still fiddling the DPR ;)) -- Aaron Scott-Boddendijk Jump Productions (07) 838-3371 Voice (07) 838-3372 Fax --- New Zealand Delphi Users group - Delphi List - [EMAIL PROTECTED] Website: http://www.delphi.org.nz
