Then you came to the right place. There are many articles on this site that you can go through and even filter down to what you are specifically looking for. And if you get stuck on something specific you can ask in the QA section.
Good luck to you.

If you are expecting people to help you with this then you need to explain exactly what the problem is and where in all that code it occurs. Just dumping your code and saying "it does not work" is not enough.

OK but i said that what problem is.
I have three page.
The default page and one user control and third ,code behind of the user control that i have put it in previous post.
My program work correctly without the ScriptManagerProxy (without Ajax) but with it doesn't work.(in the .ascx page).
<asp:ScriptManagerProxy ID="ScriptManagerProxy1" runat="server">
</asp:ScriptManagerProxy>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<%--------my code--------%>
</ContentTemplate>
</asp:UpdatePanel>
If i remove the Ajax tag that have put above,my program hasn't any problem BUT if put it ,doesn't work properly.
now do you help me?![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)

Sorry, I'm not an ASP expert. I was merely suggesting that you need to provide full details of your problem if you want people to help you. Don't assume that people can guess what you are doing.
Veni, vidi, abiit domum

see,my problem exactly is that my program without putting the ScriptManagerProxy hasn't any problem and works properly.but with it doesn't work.
"doesn't work" is in other word,not that my program has an error,no,only works bad.(i haven't a syntax error while have a runtime error only and only for the ScriptManagerProxy tag )
for more explanations:
in the code below,if we haven't ScriptManagerProxy tag in the page,we can to enter the values in the fiels and press the button to sends the values.but if we put ScriptManagerProxy tag in the page,the program isn't able to send the values because says FileUpload1.HasFile is false (fileupload1 is empty)then the if condition isn't true therefore my Query doesn't run.i hope to explain properly.

in this code behind file in below,the running of the query is dependent to correctness fileOK variable.
therefore first must FileUpload1.HasFile be true.

Hello friend's, how is the day going? I need some help here. In my asp.net website, I have fileupload to browse for zip files and save them to a download files folder. The snippet below save uploaded files
--------------------------------------
'get extension type
Dim ext As string=Path.GetFileNameExtension(fileupload1.PostedFile.Filename)
'get filename
Dim filename As string=Path.GetFileName(fileupload1.PostedFile.Filename)
Select Case Ext 'verify file type
Case ".Zip"
'save file to download files folder
fileupload1.SaveAs(Server.MapPath("~/download files/"+ filename))
Case Else
MsgBox("file format not allowed")
End Select
--------------------------------------
the following save the file name to sql Database
Dim constr=("my connection string is here")
Dim con as new SqlConnection(constr)
con.Open()
Dim SaveFile as String="insert into filestbl(filename,desc) values(@filename,@desc)"
Dim cmd as new SqlCommand(SaveFile,constr)
cmd.Parameters.AddWithValue("@filename",filename)
cmd.Parameters.AddWithValue("@desc",txtdesc.Text)
cmd.ExecuteReader
cmd.Dispose
constr.Dispose
constr.Close
----------------------------------
the question is, how can I enable visitors to specify a folder, and code the download button so that the selected file can be downloaded to a folder specify by the person downloading the file. Note, I bind the filestbl to DatalistControl. And, when the file is downloaded, the person should be able to unzip it in his/her system just as it is in codeproject. I am doing this with Asp.net. Any help is welcome! Thanks to all.

I'm not sure what you asking entirely but if a user clicks on the link to download your file the browser will ask them where to save it. So, what is your question?
There are only 10 types of people in the world, those who understand binary and those who don't.
