Re: Printers and Vista, program hangs or chrashs. dadashri4-Feb-09 2:56 dadashri 4-Feb-09 2:56  new PC, Vista installed, and then hook up to there trusty network or locally attached 5 year old printers. you 2gb ram use Re: Printers and Vista, program hangs or chrashs. st144-Feb-09 9:58 st14 4-Feb-09 9:58  Yes the PC has3.5 gb of ram. The printer causing problems is an HP and the drivers are uptodate.

If THAT program crashes, it's on the user's end. If it doesn't, you've got faulty code that is probably somehow connected to what you're printing. I assume you know that the same code that prints is also the code used to provide the previewed printout.

Thats a good idea. One user has installed pdfcreator and now can print to pdf and then on to their printer but still can't print directly from my app. I have a smaller app that use an RTF control that supports printing so I'll send them a copy for testing. The error messages I get when my program crashes point to memory corruption by the driver. Here is one example: Exception details: System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. at System.Drawing.SafeNativeMethods.PrintDlg(PRINTDLGX86 lppd) at System.Drawing.Printing.PrinterSettings.GetOutputPort() at System.Drawing.Printing.PrinterSettings.FastDeviceCapabilities(Int16 capability, IntPtr pointerToBuffer, Int32 defaultValue, String printerName) at System.Drawing.Printing.PrinterSettings.Get_PaperSizes() at System.Drawing.Printing.PageSettings.PaperSizeFromMode(DEVMODE mode) at System.Drawing.Printing.PageSettings.GetPaperSize(IntPtr modeHandle) at System.Drawing.Printing.PageSettings.GetBounds(IntPtr modeHandle) at System.Drawing.Printing.PrintController.CreatePrintPageEvent(PageSettings pageSettings) at System.Drawing.Printing.PrintController.PrintLoop(PrintDocument document) at System.Drawing.Printing.PrintController.Print(PrintDocument document) at System.Drawing.Printing.PrintDocument.Print() at System.Windows.Forms.PrintPreviewControl.ComputePreview() Here is what happened when I tried to cath the error in a Try Catch block.

Oh yeah, and make sure they're using the latest OS-compatible video drivers.

Same two errors and everything. Did you find a solution? Christian Christian, I have not made any progress. I can't reproduce the problem here and so I'm relying on my users. PDFCREATOR gets them out of trouble. (use it as the default printer, it creates a pdf an then you can print the pdf fine.) Do you have the problem on a development PC ? If so I could send you a test program and we could work on this together. Things I have tried: Make sure .net and OS are fully patched. Remove all code optimisation from my release build. Place all print functions in TRY blocks to prevent the program from chrashing. regards Stuart PS You can download my application at http://www.mapsoft.com.au (miniCAD V5) Hardware Configuartion to run SAP on Windows PC Arijit Manna29-Jan-09 20:11 Arijit Manna 29-Jan-09 20:11  I wish to install SAP in a frash system for learning purpose.

I have an application that must communicate with a piece of hardware that sends 5-bit Baudot data, so I am building a simulator to run on a different computer to send the same format data to our receiving PC for testing. The simulator is written in C# using .NET 2.0, so I am utilizing the System.IO.Ports.Serial interface. I can send and receive the data as 8-bit with no problems at all. The receiving PC has a serial card that does support 5-bit communications. In the implementation, I tried manually doing the encoding to Baudot and sending it as 8-bit using the trick given here: http://graffiti.virgin.net/ljmayes.mal/baud/baud.htm[^] (bitwise OR'ing each character with 0xE0 to set the 3 MSBs to 1, which should simulate sending multiple stop bits). However, on the receiving end, when I set it to 5 bits, I just get a bunch of boxes in the terminal output, and when I set it to 8 bits, I get gibberish characters. I'm not sure if I need to set the encoding to UTF8 or ASCII, or if it even makes a difference since I am using the SerialPort.Write() method that takes in a Byte[], offset, and length. I have tried setting it to both ways and it didn't work. Has anybody done anything like this before, or has any ideas on how to implement it? Thanks. -- Marcus Kwok Re: Sending 5-bit Baudot Over Serial Jonathan Davies30-Jan-09 0:04 Jonathan Davies 30-Jan-09 0:04  Though I've no experience of Baudot, I'd recommend you use a port monitoring program e.g. Portmon to obtain a lot more information about whats happening at the port. Though you currently see: "boxes in the terminal output ...gibberish characters"; It just might be the case that you can glean some information from the values of these characters when viewed in hex. Being able to see the way received/sent bytes are grouped and port control codes helps a great deal as well. Re: Sending 5-bit Baudot Over Serial ricecake30-Jan-09 3:57 ricecake 30-Jan-09 3:57  Thanks for the tip. I looked at the PortMon tool and it looks like it might be very helpful in diagnosing what is going on. If I manage to get it working, I will post here for the archives. -- Marcus Kwok Re: Sending 5-bit Baudot Over Serial ricecake4-Feb-09 7:30 ricecake 4-Feb-09 7:30  Thanks for the PortMon tip, using the tool I was able to see that the machine was receiving what I had expected. It appeared that the values were being received properly, but then I found out that the software was expecting the data to be encoded differently than what I thought had to be sent. I also suspect that the terminal program only recognized ASCII encoding and not Baudot, so it was not able to decode the message into plain text. Thanks for your help. It seems that the ultimate solution to my problem is application-specific. -- Marcus Kwok External H.D. Problem scorp_scorp28-Jan-09 0:22 scorp_scorp 28-Jan-09 0:22  Dear All, I have a 500G WD external hard disk. When i plug it in my PC or other PC's, the pc detect it, i goto mycomputer , i can see the drive and i can access it by double click or right click open. below is the problems: - I cant paste any thing on it - I cant create any file or folder on it - I cannt access the HD through the run command - If i goto computer management and check Disk Managment the HD does not appear. In other words as if its not pluged. Any help. Re: External H.D. Problem Jörgen Andersson28-Jan-09 1:15 Jörgen Andersson 28-Jan-09 1:15  Has it worked before or not? Can you read the files on it? Re: External H.D. Problem scorp_scorp28-Jan-09 1:29 scorp_scorp 28-Jan-09 1:29  Yeah it was working before. and no , i have no files on it . Some people telling me its the board Re: External H.D. Problem Jörgen Andersson28-Jan-09 1:34 Jörgen Andersson 28-Jan-09 1:34  Sounds like the security settings are messed up. Check the access rights on it. Alternatively, reformat it if it's anyway empty. Re: External H.D. Problem scorp_scorp28-Jan-09 1:42 scorp_scorp 28-Jan-09 1:42  How to check the rights Regarding formating , i tried it, but when i right click - format , nothing happens. Re: External H.D. Problem Jörgen Andersson28-Jan-09 1:58 Jörgen Andersson 28-Jan-09 1:58  Open windows explorer, rightclick on the drive and select properties, select the security tab. If there is no security tab, open the tools menu and select "folder options", then select the view tab. Untick "Use simple file sharing". Re: External H.D. Problem scorp_scorp28-Jan-09 2:06 scorp_scorp 28-Jan-09 2:06  same result. Nothing changed. But thanks for your follow up dude. I think it is damaged Re: External H.D.

Re: External H.D. Problem Michael Martin16-Feb-09 22:01 Michael Martin 16-Feb-09 22:01  Have you tried booting a Linux Boot Disk (ie Knoppix) to see if that can write or copy anything to the drive. It would at the least see if the problem is Windows specific, such as security permissions. If that doesn't work it would point more to the HDD.

Problem tech60316-Mar-09 16:41 tech603 16-Mar-09 16:41  You could try using the Western digital software that came with the external hard drive to have it setup properly. If you haven't done so yet i would suggest running through the setup. By default windows can not read drives over a certain size and if you have not yet run the setup, your computer may be having some conflicts with the size of the drive. If you don't have the software you should be able to download this at western digitals website.

Re: LAN problem - Do not allow to access one machine fat_boy27-Jan-09 2:35 fat_boy 27-Jan-09 2:35  Look at the various security settings, things like 'allow other computers to access this computer on the network' etc. Morality is indistinguishable from social proscription
