I have written a program in VB 2010 that dumps documentation info into an Excel file. Basically, the Excel file is a log file that keeps track of revisions for design drawings at an engineering firm.
There are approximately 20 people that have access to this program. However, I've run into issues where multiple users may be using the program and trying to send info to the Excel file at the same time. The Excel file is set to read only. My program opens the file with write access, and dumps the info into the appropriate cells, then closes the file. If one person is in the process of using the program, it causes an error with another persons system if they try to use it at the same time.
In some cases, it causes my program to crash, and it leaves the Excel file open on someones system.
Typically, my program would only have the Excel file open for a couple seconds. So, the issues mentioned above are rare, but they do happen.
I'm looking for ideas to prevent this issue from occuring.

I'm wanting to create a control that allows users to upload PDF files and PDF files only. I know that there are object properties for windows forms that allow certain file types, is there anything for win apps? Or do you just have to check the end file extension after they tried to upload it and display an error? I've never done anything with web app uploading before.

So I currently have the following:
2 timers
2 labels
1st label is "Clock" this pulls the time from the users current time zone/local time
2nd label is "UTCClock" Which would be UTC time
Now I have this for the first label: clock.Text = Format(TimeOfDay, "hh:mm:ss tt")
Which would give the users current time zone/local time. As for the UTC.. how would I add in for the UTC time from where the user is located at? I did some searches.. but couldnt find what I was looking for.. IM pretty sure its not as easy as getting the users current time zone/local time.. So im assuming that Theres a "bit more" code into getting UTC time..

I have a webserver and I upload files to my webserver from time to time. I have an ftp account which points to public_html that is main directory.
I though why give full access so I created another ftp account (e.g. test) which points to a specific folder. Now when I try to upload a file using test it fails.
For e.g.
the following code works:
My.Computer.Network.UploadFile("d:ok.txt", "ftp://mysite.com/Test/okay.txt", "main@mysite.com", "mainpw")
- this is because this a/c has access to root folder of website
now following code gives error -
My.Computer.Network.UploadFile("d:ok.txt", "ftp://mysite.com/Test/okay.txt", "test@mysite.com", "testpw")
The remote server returned an error: (550) File unavailable (e.g., file not found, no access).
Well the ftp account test has been given access to a specific folder with the name "Test". So it should at least upload to that folder.
But if I use ftp client (like filezilla) then it works.

I'm attempting to send an image and some text to a server at the same time.
I'm using WebRequest like the following to send text:
Dim ba As Byte() = Encoding.UTF8.GetBytes(query)
Dim wr As WebRequest = WebRequest.Create(Me.server_url)
wr.Method = "POST"
[Code]....
But I cannot figure out how to do both at the same time.

Public Sub UploadFTPFile(ByVal ftpservername, ByVal fullfilepath, ByVal filename, ByVal username, ByVal password)Dim clsRequest As System.Net.FtpWebRequest = _
DirectCast(System.Net.WebRequest.Create("ftp://" & ftpservername & "/" & filename), System.Net.FtpWebRequest)
clsRequest.Credentials = New System.Net.NetworkCredential(username, password)

Alright here's my situation: I have a form. This is a very small form that can be moved with the mouse (formborderstyle=none). The transparencyKey is 0,0,1. The form back color is 0,0,1.

I created an application that when a user logs onto their Windows account, a Form is displayed outlining the current Computer Usage policy set by the insitution and gives the user two options either Agree or Dis-Agree. The two options are in the form of buttons, with events that depending on what the user clicked, will create a log text file at a specified location, with enteries of Date,Time,CurrentUser, and if they agreed or disagreed. If they agreed the application after creating/amending the file will then terminate, otherwise it will update the file and then force Windows to logoff the current user.
Now I made a shortcut of the .exe of the application and placed it in the startup for all users, and yes the application loads at startup for all the users following the procedures mentioned above. The problem I am facing is, that if the current user logs off, or is forced to log off, and another user logs onto Windows, goes through the whole ordeal mentioned above, the application is denied access to the logfile that was created under the previous user, and thus crashes.
So my question is, how can I created a text file using vb 2008 application, that is accessible by multiple Windows users. I have even tried changing the location of the created file to the shared folder, but the end result is the same.

I am writing a VB.Net app that has need to send a file to web script.
1. Dim uriString As New System.Uri("[URL]"+addNew_title.Text+"&price="+addNew_price.Text)
2. Dim myWebClient As New System.Net.WebClient()
3. Dim responseArray As Byte() = myWebClient.UploadFileAsync(uriString, OpenFileDialog1.FileName)
4. Dim response As String = System.Text.Encoding.ASCII.GetString(responseArray)
There is a problem with URI that I give, it says "Expression does not produce a value" on line 3. where "uriString" used. When I used myWebClient.UploadFile(String,String) it freeze on sending, so I found out, that to continue code execution I have to use "UploadFileAsync", but it does not provide [String,String], but it requires [Uri,String].
Just for the record, I will put a screenshot of code: [URL]
What do I have to change, so code is valid, or if there is another way to upload this file?

I've come across a problem with my program; I'm using MS Visual Studio 2010 with a VB.net application. I'm uploading a log file with .log ext to my server after my program is done running. I have noticed a lot of systems fail to upload the log file because of the firewall settings of their modem. I was wondering if anyone would know a workaround to uploading this file maybe on port 80. Here is the code I use to upload the file.
My.Computer.Network.UploadFile( _
"C:log.log, _
"ftp://www.myftpserver/logs/log.log, "loguser", "password")
Like I said this works fine if the Modem firewall in on low, but fails everytime if modem firewall is in the default setting. I believe it's using port 21 right now to upload.

I need to know if it's possible to administer the users (create new users, assign them to roles, etc.) from a windows application - the powers that be don't want any administrative functionality in the web app itself.Here is the membership provider definition from web.config:
<membership defaultProvider="MyProvider">

1.I�d like to publish a free vb.net desktop application for the users to download and use meanwhile I�d like to collect usage information ex: user ip address, user�s registration information, used features, time spent� if the user allows the report to be sent back.
2.Also , in order for the user to be able to use the application, he�ll have to register it then, everytime, before the application loads, it gets verified online that it was registered, maybe validate the registration information or a valid user name and password, no critical personal information. The target of this step is for the application to be used exclusively by the registered user and maybe on his computer only.
