HTTPRequest -- Can't Connect To Website - Unauthorized 401 Error
Jun 15, 2010
I've got a vb (desktop) app (not a web app) that needs to connect to my website, I've been told that embedding my MySQL database credentials is a big mistake for several reasons.So, I've built a web script in PHP that runs on my server called web-service.php, it's located at www.example.com/web-service.php.Now, I'm trying to connect with this code:
Code:
Dim hwrRequest As HttpWebRequest = HttpWebRequest.Create("http://www.example.com/web-service.php")
hwrRequest.Method = "POST"
Using swWriter As New StreamWriter(hwrRequest.GetRequestStream) 'POST the info
[code]....
And when I do, I get the error "The remote server returned an error: {401} Unauthorised.", but I shouldn't need any credentials to access this. I'm just trying to POST a username and password to that page and have it query the database and then get the returned content, I'd prefer to use POST than GET so you can't see the user/pass in the URL (if possible).
EDIT: I used CPanel to password protect my website so it can't be accessed, after supplying my user & pass to access it, everything works.
when the Internet it's ok,this code it's okay,too.but when the Internet it's not connect or the webside server it's so busy,it's going to error,it said "Webexpection it's not handle".what should I do?
I had an exercise where I was supposed to have a button open an openfile dialog box, let the user select a file, then another button that would save the file with the extension ".bak". The author didn't give any clues about manipulating extensions -- but a few chapters back we covered string functions. So, with that in mind, I did the following...
Private Sub btnSaveFile_Click(sender As System.Object, e As System.EventArgs) Handles btnSaveFile.Click ' Where does the extension start

[Code]..
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 2)
it's just for a program registration. i would store all of the registration codes in the access database, then export it to XML, then upload it to my web host. I would then somehow connect it to my Visual Basics login form (Which I have already made). If this can't be done, having them register through the form and having all the allowed codes on the internet (So i can easily edit them)!

Background information: I am simply using Fiddler2 to monitor my HTTP connections.
When I am posting data, there is no actual post data. The data I enter into the web page is only in the hex view or the raw data. How can I send a request using raw data or whatever method with a webrequest?

I'm trying to fix an issue with an application I'm supporting (I didn't write the code). The code takes an SSRS report and renders it in pdf format. Users are sporadically getting the error indicated in the title. There is no rhyme or reason to when the error is generated (a particular report will run one time and throw the error the next).[code]
I read that the default length limit is 4MB. None of the reports by themselves are even over 350K. I'm wondering if this could be caused by a caching issue. I'm not an expert, so I need some guidance as to how best to solve the problem. I also want to understand why the issue is happening. Please note that only 2 reports are shown in the snippet - there are about 30+ reports in the full sub. I tried the proposed solution, but it didn't help (I also tried the Fiddler route, but did not see anything glaring). I thought it might be best to clarify. The reports will run fine for a while, but the execution time gradually gets slower and slower until the application eventually displays the error.
I am working on httpwebrequest method to read the php page from my site. What I am trying to do is to read the php page while read the html tags for each line, find the matched string that I have selected on the listview, then extract and get the full link of the tag called "delete" and then displaying the messagebox. Something would be like this:
[URL]
At the moment, I find it a bit difficult job to work it out on myself to get the right tag as each of them have got the same ids. The id I wish to extract from the page and get the full link is called delete. Something is like this:
If you know how I can extract each of the tag to get the delete link with the correct id while read the php page and get the matched listview item that I selected.
[URL]... Regarding this question i got some suggestions, but how to implement is confusion. Can any one help to implement so that the problem can solve.

I'm connecting to my mysql server using ODBC in vb.net, the database is shared throughout the company because it is used in an accounting program (simply accounting), each user has their own account user/pass to login to the database. I have developped a program that uses the accounting database and combines it with other information, my problem is that at least once a day I get this error when I run my program: "(10061) ERROR [HY000] [MySQL][ODBC 3.51 Driver]Can't connect to MySQL server on"and the error persists for at least 4 hours, for some reason it starts to work again later on in the day.
