I am desperately looking for a QR Code component to generate QR Code. So far the only method I have found is through Google API chart but I need an offline method.
http://theroadtodelphi.wordpress.com/2010/12/06/generating-qr-codes-with-delphi/
I cannot find any component, free or not, that can generate QR code. Any idea?
Thanks!
The company I work for has released an open source (Apache License v2) Delphi QR barcode generator called DelphiZXingQRCode. It's a Delphi port of the QR code functionality from the ZXing barcode image processing library.
Here we go:
http://www.han-soft.com/barcode2dgen.php
(source: han-soft.com)
I just aksed Google. First hit, basically.
It is available as a VCL component, here:
http://www.han-soft.com/barcode2d.php
Just discovered (months late, however) ZINT. A Pascal wrapper for this exists here. This is free, open source.
Another one is at http://www.java4less.com/barcodedelphi/barcodesdelphi.php
I just bought it this week, and took about 1 hour to incorporate QR code generation into my app (and it's pure Delphi code: no DLL).

I am intended to build an HTML5 based document editor with features like google docs, the documents are word documents and excel documents stored in server. Backend uses asp.net MVC.
I've found some ways to support doc file editing, but couldn't find any solution for xls.
Is there any good strategy or solution to do this?
Is it feasible as a solo project or it's too ambitious?
If anyone could give some directions,
Any suggestions or guidelines would help.
Why don't you use OpenXML SDK. Its an awesome SDK tool by Microsoft. http://msdn.microsoft.com/en-us/library/office/bb456488.aspx
This might be helpful: http://www.gelsheet.org/
It is an open source, web spreadsheet, that you can probably use.
use http://crocodoc.com that may help. This is not open source but it does the thing.
please try open source alternative for office 365:
http://www.onlyoffice.org/sources#document or Broadway
GDK-Backend http://www.golem.de/1108/85594.html or

I am testing a scanning application and currently I dont have any scanner to plug it in. Is there anyway to have a virtual scanner like Daemon Tools does with Virtual CD Drives?
There's a Sourceforge project with a sample TWAIN implementation, including a virtual scanner. I haven't found anything similar for WIA.
Yes, there is a pretty simple to use application called UniTwain. I am using it and it works really nice for my users. You can download it from http://www.terminalworks.com/unitwain
I would like to make people aware of GenDS
Download ZIP
According to this web page, GenDS
is a ready-to-build Microsoft C++ 6.0 project that compiles to a
generic TWAIN Datasource (DS)
I am in the process of compiling it so I cannot give further advise.

does the new Delphi IDE (2009) come with some documentation ? (kind of like the MSDN with VS).
where can you get it ? (want to have a look at it)
is the documentation good ?
i picked up a copy of Delphi in 21 days . is it good for beginners in Delphi ?
It's all available from the Embarcadero website here: http://docs.embarcadero.com/products/rad_studio/ in CHM (WinHelp) / PDF / HTML format. (I don't know whether it's any good or not.)
There is a public wiki which was started sometime back by Nick Hodges (the then product manager of Delphi). Not sure about the quality of contents though!
About the book: It is not exactly answer of your question but try grabbing Mastering Delphi by Marco Cantu. Its really the best book I have read on Delphi.
One cool thing about Delphi 2009 is that they load the summary tags written above each function in the hint you get when you mouse over your source. It's the same thing you'd get if you hit F1, but that saves a click and a wait.

The PC-SC component by nobbi.com doesn't seem to be Delphi 2009 compliant. I had to convert PChars to PAnsiChars but I still couldn't access ReaderList properly, all I could get was bunch of "|"s. So, is there any PC-SC wrapper for Delphi 2009, or a sample application of Omnikey's Sync API for Delphi? C# samples for Sync API are fine aswell, as I can use them as DLL under Delphi.
The device I'll be using is Omnikey 5321, mainly for MIFARE purposes.
That is the only framework I am aware of for Delphi. I have been keeping any eye out since as far back as 2001 and have not seen anything better.
I did some commercial SC development for the financial sector and ended up rolling my own framework for Delphi 5/7. I had the requirement to monitor card change events (insert/remove) and end up using a background thread. The solution was robust and worked very well.
The porting to D2009 should not be that difficult since the API is relatively small. Watch out for structure alignment and of course Unicode. As I recall the structure alignment required some fudging to get right (i.e. padding bytes were needed).
Best of luck!

I am looking for an app that will let me type in code ON my cellphone. I don't need to compile or anything, and its not to program for the cellphone. Just something nice to have when an idea pops in my head.
Am I completely overlooking a simple code editor for Symbian S60v3 phones?
I am looking for something similar to CEdit which is for Windows Mobile.
I've used pyEdit on my S60v2 phone, it looks like it's supported under v3 as well.
It depends on the python runtime, so you'll need to install that first.
Try YEdit or LightNotepad
try ped-s60
http://code.google.com/p/ped-s60/downloads/list
You can use visual studio :
http://wiki.forum.nokia.com/index.php/Using_Visual_Studio_6.0_with_S60_3rd_Edition
You can download the very basic edition of Carbide C++ for free from Nokia
This is built on the eclipse platform and is very good.
