Thanks,

i have tried this code in my Window Application and it works properly but when try to add Reference in my web application it give me following error

“The type initializer for ‘DllWithSettings.SettingsConsumerClass’ threw an exception.”

i have checked all for thrice and everything is done as you said above.

Thanks,

For applications I use the app.config since it is provided, however for DLL’s I have always justed used a simple XML File, and C# makes serializing to/from XML very easy. Basically I just take a simple class with only public Properties and this is what becomes the XML file. I then use a static util class that loads it up in its static constructor. Then you can just make the object available at anytime with the settings needed.

For a DLL I can see why it would care about User/Global settings, or why it should be so convoluted to store external data points for a DLL that change how it works.

del $(ProjectDir)web.config /F /Q
copy $(ProjectDir)..\\web.config $(ProjectDir)web.config /Y

This will force the deletion of any existing web.config file and copy the dlls config file over it.
Will work even with source control.
I don’t like it as it is confusing though.

I am trying to receive some inputs from the port.

I know the 8 data pins are used for output
I can receive the input of the 5 status pins but for some reason I cant find a way to receive input data from the 4 control pins. I though they were I/O. if so , what am I doing wrong?

Reading and writing can be done through PortAccess.Input and PortAccess.Output. The latter receives the address and a decimal value that is converted to it’s binary form, where each bit correlates to a pin. Here is a link explaining what you can do with each pin.

If you want to change the value of one pin first of all you need the value of the others, the ones that don’t change. If you are working with the bi-directional pins you can read the value, if you are using the write-only ones you must keep the value in your application.

Let’s suppose the value is 11011011 = 219 dec and you want to send a 0 to the 4th pin (bit 3), then you should make a mask that has a 0 in that position, 1s in all the others and make a bitwise and (&) with the current value. Here is an example:

int currentValue = 91; //01011011

int mask = 255 - (int)Math.Pow(2, 3); //11111111 - 1000 = 11110111

int newValue = currentValue & mask; //01110111 & 11011011 = 01010011

If you want to send a 1 to a pin you should make a mask with 1 in that pin, 0s in all the others and make a bitwise or (|) with the current value.

Please tell me if this helps or you need more assistance.
