Looking for a "push model" (ICAP_FEEDERLOADED) exa

[eramgarden]

I opened a question here and got a response.

http://www.twainforum.org/viewtopic.php?t=4115

So, i’m using TWAIN. I’m using this code:
http://www.codeproject.com/KB/dotnet/twaindotnet.aspx?fid=2619&df=90&mpp=25&noise=3&sort=Position&view=Quick&fr=26#xx0xx

All works. But now my manager wants to have the “push model”. But i cant find examples of ICAP_FEEDERLOADED code. Not sure how I can code for it and add it to that codeproject code…

Anyone with an example?

# Not ICAP_FEEDERLOADED but CAP_FEEDERLOADED.
For example…

while (1) {

while (CAP_FEEDERLOADED is FALSE) {

if (cancelled by user) return;

}



Scan images.

}

I am back this topic again and I don’t understand how this works..

I added this to the code that I got from that link:

internal enum TwCap : short
{
XferCount = 0x0001, // CAP_XFERCOUNT
ICompression = 0x0100, // ICAP_…
IPixelType = 0x0101,
IUnits = 0x0102,
CAP_FEEDERLOADED = 0x1003,
IXferMech = 0x0103
}

now, in the code I have this which doesnt work:

while(true)
{
while (TwCap.CAP_FEEDERLOADED )
{

}
}

— i get an error that TwCap.Cap_FeederLoaded cannot be converted to Bool…

Not sure how to use this to check for scanner being ready to scan…
