C#.NET QR Code Barcode Generator Overview
C#.NET QR Code Barcode Generator from BarcodeLib.com is a time-tested QR Code barcoding component since 2003. It can not only generate high-quality QR Code images but makes it extremely easy for users to change & set QR Code image colors, including background color and bar color.

Change QR Code Barcode Colors in IIS
Find folder "barcode" from downloaded trial package and copy it to your IIS folder, eg. C:\inetpub.
Create a new virtual directory in your IIS, name it "barcode", and connect it to the above "barcode" folder in inetpub. Then, restart IIS.
Open your web browser and navigate to: "http://YourDomain:port/barcode/qrcode.aspx?Data=ABCD1234abcd&ModuleSize=3 &LeftMargin=12&RightMargin=12&TopMargin=12&BottomMargin=12&BackgroundColor=FFFFFF&ModuleColor=000079"
To insert this QR Code image in your aspx or html page, simply pass the url to IMG tag or src value. For example: <img src= http://YourDomain:port/barcode/qrcode.aspx?Data=ABCD1234abcd&ModuleSize=3 &LeftMargin=12&RightMargin=12&TopMargin=12&BottomMargin=12&BackgroundColor=FFFFFF&ModuleColor=000079> This method will not generate any barcode images in your IIS server side.
