Hi! my name is Vladimir Bellini, i'm from Buenos Aires, Argentina. Kinda newbie with MG Enterprise/Studio. This is my 1st message at this great great forum. :-) i really appreciate any help!!

I'm having some issues :

1)- raster layer: i'm having a group of b&w tiled jpg + jgw files. This images have a white frame / border each one. They load correctly in the site explorer. And they are correctly georreferenced. But the problem is that when i view them on a weblayout (using ie/firefox) they show the white frames/borders and "overlap" each other, creating a white mesh.

I try almost everything, converting them to png+pgw , same problem. and also trying different ways of Loading resources (i tried loading as  "no bitonal merge" , as "foreground pixels are the "on" (1) bits" and as "foreground pixels are the "off" (0) bits". I also tried different configurations at the layer Style after i load the resource , at the Bitonal Image Settings i tried different "Foreground color (1 or "on" pixels) (i tried with black/white/transparent/map window background) and "Background color (0 or "off" pixels)" (again, (i tried with black/white/transparent/map window background).

Always the same result. this horrible white mesh made by the white frames/borders of each jpg/png (i never mix different extensions, i tried loading resources with both jpg+jgw and png+pgw by separate)

here is an image with the problem:

2)- Ajax autosuggest or combobox list at a search customized button.

I could find anywhere i clue about making a simple autosuggest or combobox list for a customized search. The thing i need to build is an Address search button, where i look for a db field street + number (example "Street 1234"). I do have a column on my feature class (a column in my db) with this info.

What i need is that when the user wants to seach the address (example: "Callao 1234") and he starts typing the letter "C", i want the autosuggest to show all the streets starting with the letter "C". This would be very useful so that the user doesnt need to know the Exact name of how the street is written inside the db (if its avenue or not, the full name, or things like that)

this is an example of what i really need and maybe someone can help me with a link or a way to create this as a customized search button:

3)- customized search button that searchs in more than one layer? i find some messages about this on the forum but i couldnt get a positive answer..

thanks so much!!!!
