i want to save Audio and Video Files To the Database and And Later i want to play that Files how to do that in ASP.NET
sdfsdf

|
|
|

As for saving the files, u don't save the auio file to the database, u just save its path on the server so what u need is to upload the file on the server in a path using any file upload script then u play it calling it from it's path
Best Regards

Hi,
I think you must use Windows Media Services for online play audio and video file's. I'm not recommend save audio and video file's in DB. I think you must save path to file's in DB.

MyCommand.SelectCommand.CommandText = "select * from jobSectorSubCategory where jobSectorSubCategoryStatus='A'"
MyCommand.Fill(DS, "jobSectorSubCategory")
Dim i, j As Integer

Suggestion:
Use a stringbuilder instead of a string when doing big concats.
Having said that, from this code, it seems that you will get a bunch of sectors and sub sectors as a single item in the drop down - is that what you want?
monuSaini wrote: get data but the ordering is not according to want
Further, when you talk about ordering, do you want the sub sectors to be displayed below the sectors? In such a case, what is the relation between these 2 tables - is it Sector ID, - if it is, then a single query should return you the results - show the structure of the tables.

Sry for Dat i will remember in future,
sectorTable
sectorId
sectorName
date
subSector Table
SubSectorId
sectorId
subsectorName
date
output should like dis in dropdownlist box
sectorName(a)
subsectorName(a)
subsectorName(a)
sectorName(b)
subsectorName(b)
subsectorName(b)
a & b are sectorId
regards,
Rahul

Query:
select sectorTable.sectorId Sectorid, sectorName, SubSectorId, subsectorName<br />
from sectorTable, subSectorTable<br />
where sectorTable.sectorId = subSectorTable.sectorId<br />
order by sectorTable.sectorId
Change as per table names and syntax as per database type.
Code for filling drop down:
dim prevsecid as integer = 0<br />
<br />
dr.read (where dr is the datareader object)<br />
prevsecid = dr("Sectorid")<br />
add sector info to drop down (text = sector name, value = sector id)<br />
add sub sector info to drop down (text = sub sector name, value = sub sector id)<br />
<br />
while dr.read<br />
<br />
if prevsecid = dr("Sectorid")<br />
<br />
add sub sector info to drop down<br />
<br />
else<br />
<br />
prevsecid = dr("Sectorid")<br />
add sector info to drop down<br />
add sub sector info to drop down<br />
<br />
end if<br />
<br />
Loop
You can put the foll code in a function for easy reuse
add sector info to drop down
add sub sector info to drop down
If you want the indentation as shown in your post above, add something like "-->" to the subsector name when adding it to dropdown.
Hope this helps.
