Windows Workflow Foundation 4.0 and Tracking -

-

i'm working beta 2 version of visual studio 2010 advanced learning using wf4. i've been working sqltracking sample in wf_wcf_samples sdk, , have gotten pretty understanding of how emit , store tracking data in sql database, haven't seen on how query data when needed. know if there .net classes used querying tracking data, , if there known samples, tutorials, or articles describe how query tracking data?

according matt winkler, microsoft wf4 team, there isn't built in api querying tracking data, developer must write his/her own.

gdi+ - WxWidgets draw a bitmap with opacity -

-
how can draw wximage, or wxbitmap dc opacity? looks not possible standard dc or wxgraphicscontext. beginlayer/endlayer not yet implemented in wxgraphicscontext have been 1 solution. gdi+ doesn't seem support layers, non-trivial add this. the solution seems to programmatically alter alpha channel pixel-by-pixel? void yourcustomwindow::onpaint( wxpaintevent& event ) { wxpaintdc dc(this); wximage image( width, height ); image.initalpha(); unsigned char* imgdata = img.getdata(); unsigned char* imgalpha = img.getalpha(); // manipulate raw memory buffers populate // them whatever image like. // putting zeros everywhere create // transparent image. // done, not quite... // wxdc can draw wxbitmaps, not wximage, // 1 last step required // wxbitmap bmp( image ); dc.drawbitmap( bmp, 0, 0 ); }
