Сканиране мрежа

някой може ли да ми каже как мога да сканирам локална мрежа за Online машини и евентуално да пълня едно TreeView след това.

nmap mu e majkata Inache pochwash da chetesh za

"IP Helper [IPHelper], reference"

w MSDN-a i stawash haker :)

Пусни един google със "WNetEnumResource" и се радвай на живота.
Ако пък не те радва много, пиши пак и ще се постарая да намеря добър пример.

чети и дишай по-леко

ti pod mreja "NetBeu" mreja li imash porediwid? a toj dali pod mreja ima predwid "LAN" shtoto ako i dwamata imate predwid mreja w smisala na IP i srodnite neshtata se reshawat predimno i osnowno s ping scan pri lan mojesh da polzwash i ARP scan ako twardo stoim na MS togawa moje i s WNetEnumResource werno

Ако ти се чете вж. SvrAPI для непродвинутых .Това са две статии с примерен код за реализация за W9x

Ами познай за каква мрежа и какви обекти в нея става дума... Човека иска да наплющи всички машини и техните споделени ресурси в дърво - с картинки, аз предпочитане анимирани... Ако не е така ще си изям подложката за мишката...

Nedei da si qde6 podlojkata - prav si taka e!
OS-to w Windows i mi trqbva da skaniram za online useri v LAN (TCP/IP) prez opredeleno vreme.
... no si misleh 4e ima i drug na4in osven WnetOpenResources i WnetEnumResources, no qvno nqma.

10x na vsi4ki!

taka wsichki linuxi w mrejata bez pusnata samba (a i na tezi koito ne e konfigurirana kakto trqbwa) nqma da se wijdata w taka definiranata kato "lokalna" mreja :) ako towa e OK dejstwaj s WnetEnumResources :) inache zemi procheti za SendARP w MSDN-a
