Hi Peter,
We've received your mail and according to your current question(displaying
image vertically), here are some of my understanding on this:
Are you wantting to display serveral image vertically in a single DataGrid
cell? Also, if the image counts in each cell is fixed, we can just put a
html <table> to structure the <img> tags and peform databinding, else if
the counts is not fixed, we may need to use a n additional template
databound control (like Repeater ) to display those images....
BTW, since you're currently using a webservice together with a asp.net page
to output the image as binary stream, why don't you just use an HTTPhandler
to retrieve image bytes and output them as binary image stream as mentioned
in those articles provided in my last reply?
Please let me know if anything I didn't quite get. If convenient, you can
make a complete static html page to show what you want your client page to
finally display...
Thanks,
Steven Cheng

| | Hi Peter,
| |
| | For such scenario, I think using ASP.NET HttpHandler to build such a
| image
| | generator service is the perfered approach. We can put the data
accessing
| | code in httphandler's processMessage code to retrieve image streams and
| | flush them out .... Then, other pages can reference the httphandler's
| url
| | (which use querystring parameters to specify certain code logic
| | options....). Also, the ASP.NET 2.0's WebResource.axd is just such a
| | HttpHandler which help retreive resources from assembly and flush it
| | out....
| |
| | Here are two web articles discussing on building a Image generation
| | httphandler in ASP.NET:
| |
| | #A simple ASP.NET photo album
| |

| | | Thanks Matthew. The web service is designed to generate the images.
| | | The source comes from vector based files that require conversions.
| | | Since these files can change at any given time, the latest image must
| be
| | | presented.
| | | So the web services acts as a graphics layer much like database acts
as
| a
| | | data layer.
| | |
| | | The client is foremost layer and must be separate from the complexity
| of
| | the
| | | graphics process.
| | | So I really do need some sort of streaming mechanism.
| | |
