[fpc-pascal]port access as simple user
Title: Üzenet Hi! I like to access ports as a simple user. Only root user can do it. So i like to run a program with root user and first fork or execve to the same program with setuid(). So how can i run a program with root user whene i logged in with a simple one? Can i fork port access rights? Best reg. #Tsch : Balázs Csaba

You must make your program "setuid root". i.e. compile and install as root, and then run "chmod 4755 yourprogram" The program will then be run with root permissions.

[fpc-pascal]Resource file syntax...
Does anyone know where I can get some documentation and examples on Windows resource files? I'm mostly interested in imbedding icons, menus, dialogs gadgets and version info. Thanks.. - L D Blake ___ fpc-pascal maillist - [EMAIL PROTECTED] http://lists.freepascal.org/mailman/listinfo/fpc-pascal

http://www.users.on.net/johnson/resourcehacker/ It can handle all exe files, that compiled with resources. Can get or edit menus, dialogs, icons and not only text mode. You can see menus and dialogs in wyswyg mode. #Tsch : Balázs Csaba > Does anyone know where I can get some documentation and > examples on Windows resource files? > > I'm mostly interested in imbedding icons, menus, dialogs > gadgets and version info. ___ fpc-pascal maillist - [EMAIL PROTECTED] http://lists.freepascal.org/mailman/listinfo/fpc-pascal
[fpc-pascal]ASCII plotting
I would like to include some simple "ascii plots" in my textual output files, like : 10.0| ** | * * | * * |** |** * * * * ** * * * * * * 0.00|---*-*- -3.5 3.50 I've coded something simple ... three times now... and I now realize how complex this can get. Lot's of isues with changing scales, optimizing the ouptut for very granular rows and columns, syncing the plot with the labels, choosing "good" labels, etc. For example, I found that I need to draw a "line" between the points otherwise the vertical line segments get lost: 10.0| ** | * * | |** | | * | * |* | * | * * 0.00|---*-*- -3.5 3.50 But now I find that if I choose too many X values then the line segment drawing tends to make the make the drawing "fat", especially at the tails: 10.0| ** | * * | * * |** |* * |* * |* * |* * ** * **** ** *** 0.00|---***- -3.5 3.50 Because I'm plotting discrete functions, changing the number of X values requires a complicated interpolation procedure... So, does anyone, by chance, already have a unit for doing this? -Alan Mead __ Do you Yahoo!? Yahoo!

For Linux I've got an X interface (xmaple) and a text interface (maple). The text interface does drawing plots as text. It even can draw 3D plots in text mode! Probably you have the chance to examine this program. Then try these feeatures!

I don't want to get stuff out the idea is to add stuff in. - L D Blake ___ fpc-pascal maillist - [EMAIL PROTECTED] http://lists.freepascal.org/mailman/listinfo/fpc-pascal

In reply to your message of July 29, 2003 > This is a documentation page of the resource compiler GoRC^ > http://www.jorgon.freeserve.co.uk/ResourceFrame.htm Now THAT was helpful! Thank you. I also found out I was missing a couple of help files from WinSDK I "borrowed" from Delphi7... one of them was the documentation on the resource stings. Between the two, I should be on the way!

One thing I found helps with that "fatness" problem you got in a couple of spots is to confine your screen coordinates ... x,y : byte ... less chance of fractional or out of range returns causing the plotting decisions to wobble. (Text mode is decidedly low res, so use a low res numbering scheme to match ). - L D Blake ___ fpc-pascal maillist - [EMAIL PROTECTED] http://lists.freepascal.org/mailman/listinfo/fpc-pascal

Re: [fpc-pascal]socket requirements.
What my program would need is: When a packet is received: source address and source port When sending a packet... supplieing a dest address and dest port. The last could be done with connect. How to do the first is now the question... Maybe with recv... but the doc says it needs to be in a connected state? Also maybe with getpeername This seems to be a weird way of working with datagrams... ___ fpc-pascal maillist - [EMAIL PROTECTED] http://lists.freepascal.org/mailman/listinfo/fpc-pascal
