Displaying Htm Contents In Browser Via Response.Writefile In ASP.Net
Apr 18, 2012
I'm working on a site that I've inherited that's built with ASP.Net, which I'm only slightly familiar with. One of the pages allows for a link to a document (word or pdf) that, when clicked on, prompts the user to save or open the file, but does not reveal the true path of the file. This way it prevents users from pasting a url to a file - the link is to an aspx file that checks for a valid session, and then retrieves the file.
Anyway, because there's a lot of legacy code, I need to do this with a bunch of static htm files as well, however these files need to be displayed rather than prompting the user to save them, which is what happens now. I tried changing the content type to application/text, application/html, text/html, etc. and that didn't work, then tried adding a response header of content-disposition inline. When I do that, build, and try linking to the file, I get a couple of runtime exceptions:
[FormatException: Input string was not in a correct format.]
Microsoft.VisualBasic.CompilerServices.Conversions.ParseDecimal(String Value, NumberFormatInfo NumberFormat) +206
Microsoft.VisualBasic.CompilerServices.Conversions.ToLong(String Value) +110
[Code].....
Do I have to do something with an htmlwriter object or something? Can't I just have it open a new browser window with the file displaying or does it have to prompt the user if used in this way??

I have been trying to discover how to make the contents of a form expand or retract in response to moving its borders by grabbing them with the mouse, or by use of the 'Maximise' or 'Restore Down' controls.The explanation in �Help� concerning TableLayoutPanel, Panel, Anchor and Auto size doesn�t help much, especially as it I can�t get it to work.

I am having a hard time displaying the contents of a text file that i read into an array. I read the text of the text file into an array but then i need to display it but i can't seem to get it. I also need to create a criteria to match whatever letter is entered into the textbox and display the contents of the file only beginning with that letter. I know i have to use a substring to read only the first letter but I can't even display the contents of the file from out of the array. Here is what i have so far.
Dim sr As IO.StreamReader = IO.File.OpenText("CRAYONS.TXT")
Dim color(50) As String
Dim arrynum As Integer

I'm looking at a website using Internet Explorer and Firefox. In each browser I select view source and see the website's URL in the links. These links were concatenated together using HttpContext.Current.Request.Url.Host in the code behind. However, when I use netcat or Burp Suite v1.3.03, looking at the same links I see the servername instead of the website's URL.
My question is - Why does view source in the browser display different links in the page source than what netcat or Burp Suite outputs? Is the browser rewriting stuff? My thought to correct is to have a web.config setting which is used to create the links. Next question - Does anyone know of a configuration change to make to IIS to return the URL instead of the server name or a .NET function that I should be calling instead to get the URL that the website is running as.

ok here is my problem, im making a little app for school since our school blocks pretty much everything so here is my plan a student makes 2 gmail accounts one for school one at home.
in the program at school (client) they put a site request into a textbox and they hit send, the request is then sent to the home pc gmail account and another app on the other side downloads the full site that they have requested and then sends them an email back with an attachment of the complete website, it is then opened in a browser and they have the site, simple idea and it would be easy except.
my school blocks the smtp protocols in vb, even outlook cant use gmail accounts only the schools registered email, however, you can access gmail on the internet without any blockages and you can send and recieve on the gmail website.so how can i use a webbrowser control to log the user into there gmail account through a custom gui, and send a string like www.facebook.com to the home pc gmail account, and then use the web browser controll on the students laptop to recieve the response email through a web browser, is there some kind of gmail api i can use?

Recently I have browsed the web for ways to display a list of files and folders in a list box. I have successfully been able to display files in drive C and get a nurerical value telling how many files were found. However my efforts have been hampered by three distinct problems. I have some experience using batch files and when using them you can state things like "%WINDER%" to go directly to windows folder. I am wondering if there's anything like that used for navigating. And if so could an example be made of it just for clarity?
My second problem is I cant seem to be able to display files and folders. I have been limited to one or the other. That and I cant figure out how to navigate into them to display there contents. The next problem I have is simply having a user interface so you could type a file path or file extention and have the program navigate to it. Is it is possible to click a file path in a list box and chose to delete it. My second last Q how do I display all files and folders including hidden files? And How can I count all files and folders with there contents to dissplay in a listbox.

I am having a problem displaying a custom array list I have in my code. (BTW. It is 1am where I am. I have been at this for a long time so I apologize if I don't make a lot of sense).I built an arraylist of objects from a custom class. The arraylist contains 2 columnsdimensions.The first is type string, the second decimal.I am now attempting to take my arraylist and display it in my form. I have tried using a listview and iterating through it, but unsure of how to split the two columns up. I have tried something similar to the following I found in another forum:
Code:
For i As Integer = 0 To arSearchArray.Count - 1
Dim item As String = CType(arSearchArray(i), String)

I'm working on a desktop replacement project and was wondering if it possible to have a form which can be docked to the side of the screen that contains all the task tray icons and functions (I would imagine that the functions are held within the task tray/icons themselves as they act as little programs) and would update automatically whenever anything is added.
Also, I'd like it not to have a taskbar entry while running, just having it sit there on the screen until needed.

I am using CreateFile, WriteFile and ReadFile API calls to write some data to a USB device. The code I have works perfectly on 32 bit systems. CreateFile gets a handle to the device, pass that handle and some data to WriteFile and read from that handle with ReadFile.My problem is, the same code does not work on a 64 bit system. The error returned from WriteFile is 6, The handle is invalid. I've checked the handle for validity on the CreateFile call and it is a valid handle. A call to LastDLLError() returns 0 after CreateFile.The "file" is being opened for overlapped communication and the overlapped init calls are also returning their proper values.is there some sort of different consideration I need to make because it's a 64 bit system? A different flag? A different call altogether?

I'm currently using an unmanaged library written in C++ and imported via <DLLImport()> to access a dos virtual device driver, and that works fine. However, I'd like to be able to do this via my .NET application (without requiring an accompanying DLL). So, I'm trying to write to the virtual dos device using the kernel32 API and WriteFile, however I receive the error: "Attempted to read or write protected memory."
Mapping to the device with DefineDosDevice and CreateFile (also in the kernel32 API) works fine and returns a valid file handle, however when I attempt to write to the file it fails. I've even tried marshaling the data to an unmanaged block of memory using InteropServices (AllocHGlobal and StructureToPtr) and then writing it from there, however I still receive the same error.

Oddly enough, I've worked around this issue, but it's still annoying me. I worked around it by sending too-long writes, with padded zeroes; the code works but sends a few hundred unnecessary bytes. Specifically, I need to send exactly 992-byte packets instead of 7 or 19-byte packets

I am trying to create a code where I placed sets of numbers in an array.I'll use a masktextbox to have the user enter the numbers to match what's in the array. If the user enters the number, ex: social, and the data is correct (matches the numbers in the array), something happens if the number entered in the masktextbox does not match any of the number sets in an array then another thing happens.The masktextbox so far only validates format and gets number only, however, I want the number entered to match whats in the array.

I am creating a webbrowser with Visual Basic, and I have finished everything but this: When I click on an external link, (I.E. On a photo, or on youtube) it opens up in a new IE window. I want it to open in my browser, not Internet Explorer.I have read everything I have found on this subject, but it is all for normal web browsers. I want to do this for a tabbed web browser, not one without tabs. Basicly, I want to use this code with my tabbed web browser that uses tab control.
Private Sub WebBrowser1_NewWindow(ByVal sender
As Object,
ByVal e As System.ComponentModel.CancelEventArgs)
Handles WebBrowser1.NewWindow
[code]....
convert the code to be used in a browser with tabcontrol? I tried, and it works with one that DOESN'T use it, but I want to use it with my browser with tabcontrol. And, I have read ALL of the ones previously given to other people.

I coded a web browser over the course of a year called Nova - very advanced with tabbed browsing, bookmarks, homepage, history, etc etc etc etc. I could go on all day about how advanced it is. But.. there is one flaw. You cannot make it the default browser; I don't know the code!I already know the CommandLineArgs stuff so it actually opens the HTML file rather than just opening the program; in fact, I already can make files open with Nova completely. It's just the other stuff - you know, when a website is to be opened from a help file or something, it opens with Nova, Windows recognises it as the default browser, stuff like that.

Other topics around the Internet are all unfinished topics, so I'll ask this myself. How do I set a self-made browser as the default browser? I know it has something to do with accessing the registry and checking what the value is in some places, but I'm not quite sure. Now, I've made this browser called Nova;
very well coded and advanced, tabbed browsing, bookmarks, homepage, history, can change default search provider, uses Gecko as its engine so it's not just an IE shell, etc. It's been developed over the past year and will still continue to be developed. I'm almost ready to release the first version - but I just need this annoyance solved.
