may layout napo ako sir....ang plano ko po kac sir, gagamit sana aq ng ToolStrip..

tapos ang gusto mangyari, halimbawa pinindot ng user ang button na "Add Vendor" na nasa ToolStrip, ung contents lang ng window sa baba ng toolstrip ang magch-change, d na kailangan ng panibagong form para sa "Add Vendor"... pwd kaya un sir??
Click to expand...

para sakin pwede yan. para sakin din ikaw lang ang mahihirapan dyan, mas mahirap imanage ang code kung mag kakasama sa isang form.

nung bago ako ganyan din nasa utak ko kasi yun ang pagkakaintindi ko sa mga nagtuturo sa school na maganda compressed. pero hindi pala. mas maganda ang program kung mas madaling maintindihan ang code at imanage para mas madali din sya iturnover sa ibang programmer.

pwede po yun kahit yung default lang ng vb.net. instead lang na ibind mo sa datasource yung table mo ilagay mo nlng isa isa sa label.
magdecide ka po muna kung alin gagamitin mo.

bkt? hindi ba niloloadan ang globe tattoo? well if you don't know yes niloadan yon. and if you try to open that SIM card din yan na pwede gamitin sa phone. or yung nasa PHONE na SIM pwede rin ilipat.

anyway i hope hindi kita na offend nagulat lang ako sa tanong mo. if you have more questions post ka lang dito. i learned serial programming right here kay sir eric and now i built 5 projects para sa office ko using that knowledge so stay put marami ka makukuha dito.

Click to expand...

ang ginamit ko dyan yung ports namespace


system.io.ports

yun ang "SPort" sa code ko na binigay sa taas.
then yung AT commands nlng kaylangan mo na accepted ng device mo.

apart from that imagination and logic nlng ang kaylangan.

Re: VB.NET Programming Corner! UPDATED!!!

Here is an ebook for AT commands. although yung ibang commands bka hindi supported ng mga broadband modems like globe tatoo. pero yung basic naman andyan.

yung sa serial port sa msdn nyo nlng tingnan.
