After my vb.net code uses WebClient to do an FTP UploadFileAsync upload, this subroutine is called: Sub FtpCompleted(ByVal sender As Object, ByVal e As Net.UploadFileCompletedEventArgs) End Sub
[Code]....
I am uploading a file from a C# application to an ASP.Net website, both written by me so I have access to the code.But, it is working for a text file (1KB) but not for a MOV file (77MB).
In both cases, I am using UploadProgressChanged to get the progress. The TXT file goes to 100% while the MOV file goes only till 50%. When done, I only find the TXT file saved on the server but not the MOV file.
Why is this happening? How can I get it to work?

have any examples for UploadFileAsync? Including both server and client examples?
View 1 RepliesI am upgrading from VB6, using MSXML.XMLHTTP object. I believe I have gotten the .Net Webclient to send the form fields, and a response comes back from the site, but everything in frames. The VB6 code automatically had all of that data, how can I get that in .Net I know this is a Newbie question if you can point me to documentation,

View 2 RepliesI created an app and what it does is takes a screenshot of your desktop, saves it, then uploads it to ftp. After that it closes. What i need it to do is continuously do that via what ever the interval is set to. So if the timer1 interval is at 12000 then i need to to take a screenshot and upload it every 12 seconds. Can someone tell me why is keeps closing after it uploads the 1st screenshot? [code]...
View 3 RepliesCurrently whenever a user uploads a file through our website, it gets put in a folder such as:
www.domain.com/Uploads/Docs/filename.doc
However, I'd like to move this to a subdomain such as:
uploads.domain.com/Docs/filename.doc
This is mainly because I'd like to keep the files uploaded by the user, totally seperate from the web app.
However, currently I use an ASP.NET FileUpload control to upload the files, by doing something like:
myFileUpload.SaveAs(Server.MapPath("/Uploads/Docs/filename.doc"))
How would I change this line of code to be able to upload to the subdomain easily?
I am trying to create a console application that will upload an updated .html file to a website each time I run it, I have found previous codes that download the files but I want to upload instead. So basically I am trying to create an FTP program (but only one that uploads) in a console application.
View 3 RepliesI am currently having a headache on how to solve this problem that i am facing. here is the situation: I have a combobox and a list box on the main form. The combobox will get the data from the ms access database. In the database, i have the details of a person's IC, Name and DOB say for eg on one entry I have D215311523C,SHAWN,13/04/1987 So now, my combobox on form load will show the list of dates in the database to allow the user to search base on the date itself by clicking on the selected date. So when the user clicks on the particular date say 13/04/1987, people in the database whose birthday is 13/04/1987 will be shown on the listbox.Meaning to say if i have 3 entries whose dates are the same 13/04/1987, 3 entries will appear. If there is only two entry, then two results will be shown. But now, when i do a single click on the date, one result will be shown. That is correct. But the problem is when i click on the same date again, three of the same results will be shown on the list box. that is it will display : 13/04/1987 13/04/1987 13/04/1987 which is not the case. Then it will show more duplicates of the same results if i click more times on the same date which should not be the case.

View 2 RepliesI am encountering the following issue So i have a device that sends stuff at the serial port, i then parse it and put it into an array of bytes like that:
Dim HCI_Command_Rcvd_Byte() As Byte All good till here What i wanna do is make an array and put this result every time the serial port gives me a new result, for example:

Basically what i wanna do is let the port parse the messages, fill in the array with the result at an empty spot in this array and then i will have a separate thread that will look in into this array in each non empty space and after it looks into the non empty space it will use or discard the info and also mark this space as empty (after it checked)

I just read about DataSet in VB.NET, it uses disconnected concept. My question is: if my apps has "List All" button that query data from 1 table in the database, and that table has "very very very" many rows, so my DataSet will be filled with those data and eat up memory. Can I limit the data that being put to the DataSet from that query? But I want to be able to retrieve the next data from the same query if the user want to see it?
For example:
I have 1000 rows in my database, and i query all of them. But I just want 200 rows being inserted to my DataSet, but if the user want to see rows number 201 and so on, I want to be able to retrieve the next 200 rows, and so on. So it just like cutting those data into a group of 200 rows. Can I do this with the concept of "disconnected" of the DataSet?

I have set up a method in vb.net and in xcode for encrypting a string using as far as i can tell the same parameters for an AES encryption.I've looked all over the place but cannot find information on whether they use the same encryption algorithm and settings.
this is the vb.net code:
Dim encryptAES As New AesCryptoServiceProvider()
Dim encoding As New UTF8Encoding()
Dim encryptor As ICryptoTransform
encryptAES.Key = encoding.GetBytes("12345678901234567890123456789032")
encryptAES.IV = encoding.GetBytes("1234567890123416")

as per usual i am a little confused. I know DownloadStringAsync runs on a threaded pool with a default min and max threads limit, but what confuses is how would i call DownloadStringAsync say for example ten times.Example.I have an array with 10 URLS. Surely i would not use a for each loop of the array index to pass the url address while each time calling DownloadStringAsync(New Uri("someArray(index)") surely we can pass say a range of items from the array and let DownloadStringAsync decide on the threaded pool how many to process each time?
