I try several samples in the internet and none of them work - the scripts are not executed- (maybe because are for pre Delphi 2009 unicode?). I need to run some python scripts and pass arguments to them, like: python "..\Plugins\RunPlugin.py" -a login -u Test -p test And capture the output to a string & the errors to other. This is ...
we've been using Pro Essentials graph (gigasoft.com) but it doesn't play nicely with delphi so it's been causing problems. we need to display waveforms and bar graphs (not at the same time). the waveforms could have thousands of points. we need something pretty full-featured that's a "living" product. our app is a native win32 delphi...
Our Delphi 7 development team stores form files (dfm) in text mode, and uses a source control system (Subversion) to track changes. Sometimes, we noticed that a form file returned to binary format between revisions, causing diff tools like TortoiseMerge to complain. Using the Subversion change log, I can see that the DFM file was store...
The feature matrix for Delphi says: 'Added in 2007! SOAP features updated to support Amazon, eBay, MapPoint, and more'. I was able to build a working client, without special workarounds for the Amazon Simple Queue Service. With Amazon SimpleDB, I ran out of luck (but not because of Delphi, see here). Which Amazon web services have you ...

Happens on XP Home & Vista Business Ultimate 64. I use an alias for the db. Database is Firebird, middle-ware is IBO 4.7. I posted this in another thread, but know I have a lot more i...
How can I build a stand-alone SOAP-based Web Services using Delphi? Must work with Delphi 2009, but it'd be nice if it worked with older ones too. The built-in WebBroker Web Services creates CGI or ISAPI. It would be nice to create a stand-alone executable that I can control from bottom to top, especially during development. ...
I have a TGraphicControl descendant which paints rather slowly. There's also a TWinControl descendant, this one paint fast. Both controls are on the same TPanel. While scrolling, the TGraphicControl is updated more often than the TWinControl, so they look out of sync. This updating is done by Windows and/or the VCL, not by my code. I c...

The USB chip acts as a communications bridge, allowing the programs to communicate with the micros over SPI/I2C/UART. The programs can configure the micros, and get back status ...
