I seem to remember reading the MSDN somewhere that there was another method to download files from URIs other than using the webclient object. I'm trying to download some raw php files but every time I use the webclient object the server interprets them as an HTTP request and instead serves the default web page that the php file builds and not the php code itself.
View 3 RepliesI am trying to use WebClient to download a .zip file from my server. In debugging mode the code works perfectly, but when I deploy my software the file does not even begin to download.After my program checks to see if an update is available, it should download the .zip file from my web server via the following

I'm downloading a file from my website using WebClient.DownloadFile(),I'm wanting to do it asynchronously, so my UI stays responsive, that would require me creating an array of web clients, is that bad practice? Or is it acceptable?I have looked into FileWebRequest, but thought WebClient looked easier to implement.

I'm trying to filter submitted web sites by attempting to browse them while bouncing the request off of OpenDNS. If the page received is the OpenDNS page, I'll assume the page shoudld be blocked.
How might I accomplish this task using the System.Net.WebClient class?
My program takes user input, replaces all spaces with "+", then inserts it into a search url for a specified web host. For example, the user enters:"How long is a foot?"
The generated URL (in this case I'm using dogpile.com) is:
"http://www.dogpile.com/info.dogpl/search/web?&q=How+long+is+a+foot"
This method has worked before for me, but now I just get an Internal Server Error every time the code is executed.
Basicly I'm downloading XML files with the Webclient class for processing and caching in a local database. There are three different categories of data, each contains 1 to n numbers of XML files. To retrieve the XML file I ask the server with following parameters in the URL:

I've got an app which uses a background worker to copy files. It works fine but some files are quite large and it "appears" as though the app isn't doing anything. Is there an alternative to the File.Copy method of copying files so I can report on the progress of individual file copies, like the percentage complete?
View 19 RepliesI am working on a VB Console Application that takes an Autocad drawing type DWG and converts it to a PDF using a shell command that calls a third party application. In this case, acmecadconverter.exe from www.dwgtool.com. Then the PDF that is created needs a unique watermark, so I call a second application for that called pdftk.exe from www.accesspdf.com/pdftk/.
Everything works as intended, except when I try file names that contain spaces. The file system object does not tolerate spaces in the drawing file name. For instance, the following command gives me a system.io.filenotfoundexception...

View 16 RepliesI am trying to use the UploadFile WebClient method to a HTTP server which is operating on a device, however when I do this from my code at the client end (a PC), the server crashes. If I upload the same file from my browser on the PC to the same device running the same server, it works just fine. When I track the code on the web server there appears to be a difference in the header which is sent to the server. It is a 'Post', however the filename doesn't seem to be there. Is there anyway of reading the data that the UploadFile method sends?

View 8 RepliesI've managed to narrow down my issue to a simple annoyance. I had a Webbrowser control mostly coded to navigate around an Oracle CRM On Demand site to generate metric reports, but then realized when I tried to build in the auto-download part, that the Webbrowser object wasn't going to give me the behind-the-scenes control I wanted. Searching online, it seems the Webclient control might be a better route. However I'm stuck trying to get by the login page so I can use the Download-File method to get my generated xls report. [Code] But every reply from the server has "Sign In Error: Both a user sign in ID and a password must be given." which tells me the form/post data isn't getting where it needs to go (It thinks the form is blank at [Code].
The above username and password are bogus of course, but once I can get a different reply then 'the fields are blank' I can worry about correct logon information. I'm just not sure what I'm not doing correctly or if I need to include something else. Since it's a publicly accessible site and I'm stuck getting something in the form to be 'seen', it should be easy for others to try and test.

Currently, I am try to get the email addresses that have been saved or stored by the user of the computer. This isn't the emails that the user has sent or received, or the contacts he/she has in his address book. Just simply the email accounts that have been accessed from the computer.I know that there are some locations stored in the registry that have the email account. The email addresses that are used on the current computer. I just can't seem to find them on my computer.I am not sure if the registry is the only place to find it or if it stored on the web browser such as internet explorer or google chrome.
View 1 RepliesI am writing an application that connects to a specific com port. This com port can change depending on how many physical ports are on the PC, and if other USB devices have installed com ports before this one.
I have the communication to the com port all working great, but I need to get the com port description not just the "COM#" which is all I currently get.
I found in the registry where the description is stored but am having trouble doing what I need.
In this key:
Code:
HKEY_LOCAL_MACHINESYSTEMControlSet001ControlClass{4D36E978-E325-11CE-BFC1-08002BE10318}
there is a varied number of sub keys. The are numbered 0000-NNNN depending on how many ports you have. Inside each of these keys, there are multiple values, although I am only interested in one or 2 of them.
My problem is, that I do not know how to get a list of the subkeys (the 0000-NNNN keys/folders) from the original key I posted. I have looked through a few registry tutorials, and I can view the default value in the listed key, but I could not find how to list the subkeys of the listed key.
Does anyone have any sample code they could share that shows how I can get a listing of subkeys, and then run through those subkeys checking for a specific value in one of the strings contained in the subkey?

If not, then go to another form. The problem I am getting though, is when the version is outdated, the file will go to download the new .exe and it gets and error saying "File already exists"

I've got a code in VB that will download a txt file from a website. The problem is I want this file to be downloaded into whatever folder that my program is in. for example, if my program was in C:
andom_folder then I would want this txt file downloaded to C:
andom_folder
Here is some of my
My.Computer.Network.DownloadFile _
("http://www.mywebsite.com/test.txt", _
"define where file should go here")
But in the spot to put where to place the file, I can't just put C:andom_folder because individual users may have this program installed in other parts of there computer.
