What do you mean by run time? If you want to check the checked property of a control inside gridview then first you need to search that control and then you can check whether it is checked or not.

using this code you can delete the file.
System.IO.File.Delete("path of the file"); Check about the permissions setting.

Load handling while using ffmpeg.exe

I am using ffmpeg.exe in my project to convert the uploaded video files(.wmv,.mov,.avi etc) to flash movies files (.flv). I have used process.start() method to execute the executable. In such a scenario every time a file is uploaded, a new process is created for the ffmpeg.exe which converts the uploaded file. This will increase the load on the server as the number of user increase. How can overcome this problem? Can anyone suggest some way out

Why are you converting videos in a website at all ?

I'm not sure what you can do. Even if you had ahold of the process, how would you know to end it ? Perhap by the video file being done ?

Well thanks again Christian, well you are correct I am ending it after the video file is getting converted and saved. I have a requirement for which i have to convert file in my website. This conversion thing is working fine but Then I thought executing an exe file will increase the load on server. Is there any way to tackle the problem..? Hope I have made my problem clear in last post.

I was wondering instead of a process getting created for each upload can we have many threads for a process....? I am just giving an idea....I don't know if it is possible.

You can create a windows service and install it on server. This service should look into the uploaded directory, and do the conversion. Since you are doing this in a service, you will get complete handle to the process.

All C# applications should call Application.Quit(); in the beginning to avoid any .NET problems.- Unclyclopedia

Well i had thought about that too but our scope is limited because of some reason. We have to implement it in the business logic of the web application itself. As i had asked in the previous post...will the multithreaded concept help...?

Hi,

i have 2 tables in my database
ihave used text boxes in My code behind to display it.(asp.net and c# with sql)

i have given sql connection using data adapter and dataset

i can view the datas from the database

my doubt is how can i show the error message if there is no information in the database

_AK_25-Nov-07 23:33

25-Nov-07 23:33

If you are using dataset then you can check the rows.count property. If it is returning 0 then there is no records in the database.
