Asp.net - Chrome Saving Streamed File As .gz
Oct 30, 2009
I have files stored encrypted on disk in an unnamed, unordered state. when the files are downloaded by the user, the client is redirected to a download handlers (.ashx) the data is loaded into a stream, decrypted and sent to the client. Now this has worked fine until recently,
It works fine on all browsers except chrome where the file is downloaded as a .gz file and is unreadable?
I have stripped out the stream fetching and cryptography parts for brevity (keep in mind this works perfectly on IE, Firefox etc)
Private Function StreamFile(ByVal context As System.Web.HttpContext) As Boolean
context.Response.Clear()
context.Response.ClearHeaders()
[Code]....
Note that the filename is codekiwi.txt and the contents are some simple plain text, the file gets saved as codekiwi.txt.gz and contains gibberish.

here is what I'm trying to do (partly in pseudo code):
Public Sub KillProcess(ByRef strProcessToKill As String)
Dim proc() As Process = Process.GetProcesses
For i As Integer = 0 To proc.GetUpperBound(0)
If proc(i).ProcessName = strProcessToKill Then
proc(i).Kill()
End If
[Code]...
The killprocess part works fine. However, if I try a "For Each App As Process In Process.GetProcessesByName("chrome"") approach and have several chrome windows open then it will display the question 5 times if there are 5 chrome processes open.

I would like to add a virtual microphone (similar to how you can have a virual CD drive and then mount ISO files on it.) so that it can be selectable in programs like MSN and skype. But have the source of the audio be streamed from over a network(I know how to stream the audio over the network in VB.net) but how do I get that audio which has been streamed as the input to the virtual microphone?

is it possible to use stored Chrome cookies in VB.NET?
I need to periodically check certain data on a webpage that requires login. I know I can login with Internet Explorer first and then later use the stored Internet Explorer cookie in my application to visit that webpage.
The problem is that I use Chrome to browse that website. When I first login with IE in order to check the data with my application and then browse the website manually with Chrome, the Chrome cookie is suddenly invalid. Then I need to login with Chrome, but then the IE cookie is suddenly invalid again and my application can't check the data anymore.
So, it's not possible to browse the website (logged in with Chrome) and periodically check the data in the background (logged in with IE) at the same time.
I really do not want to use IE to browse that website. The only way to make this work properly, is if I could use the stored Chrome cookie in my application, instead of the IE cookie.

in my application, I pull in http code from the server side. When this code is placed into the application - the event will happen when clicked in IE, but not in any other browser. Heres the part of the code that deals with the image that is clicked and the event.
<img canExpand="true" style="cursor:hand" id="img34635" src="../images/plus.gif" EntityID="346" EntityCat="35" onclick="LoadChild(this.EntityID, this.EntityCat, 0, this.lnEquip)">
LoadChild is a javascript function on the client side of the page. When the image is clicked in anything other than IE , nothing happens. Can anyone see why this is happening? It may be a formatting issue.
edit - here is the javascript function load child
function LoadChild(lnEntityID, lnEntityCat, FullExpand, EquipID) {
document.getElementById('dropTypes').disabled = false;
document.getElementById('dropTypes').style.background = "white";

my code is to handle the maxlength in the multiline textbox (textarea) so it works just like maxlength in the singleline text box , so I handled it onkeypress , but if I copy and paste , i want to substring the length to the maxlength from the clipboard , just to behave like the singleline textbox, the problem that the clipboard works only for the internet explorer but it doesn't work in other browsersso function in JScript.js.[code]

I have a several form elements that I am dynamically creating with javascript when a user changes a number value in a textbox, by filling the innerHTML of a div like so:
dfinnerhtml = dfinnerhtml + "<div class='field'> ";
dfinnerhtml = dfinnerhtml + "<textarea name='textbox1" + suffix + "' type='text' id='textbox1" + suffix + "' value='' rows='4' cols='20' class='field'></textarea> ";
dfinnerhtml = dfinnerhtml + "</div> ";
Then, in the aspx.vb code behind, when the user clicks the Save button, I run through a series of Requests to try and add the values that are in these form elements to a SQL string:
Dim DFTestValue1 As String DFTestValue1 = Request("textbox" & c.ToString)
where c is a loop counter to the # of textboxes created (the input value mentioned above that triggers the create) The problem here is that this code works in Internet Explorer but not in Firefox or Chrome. The Request() value returns null and nothing is saved. I hope I've explained this well enough.

Google Chrome has a handy feature where I can click a download link and drag it into a Windows Explorer window, and then drop. After dropping, Chrome then downloads the file and it appears where I dropped it.
I would like to be able to drop from Google Chrome into my application, but it seems it isn't so simple. I have a DataGridView called gridFiles, and the following code:
Private Sub gridFiles_DragDrop(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles gridFiles.DragDrop
If e.Data.GetDataPresent(DataFormats.FileDrop) Then
[Code].....
EDIT: So it seems that with regular URLs, I do get the proper dragged-in UniformResourceLocator format. The behavior I am seeing occurs with the download links in Gmail. It probably happens elsewhere, but I am not sure. When a gmail attachment is dragged from Gmail into my application, I get a FileDrop.
Doing some more digging, it seems that Gmail is using the download_url attribute of the anchor tag. I have never heard of this before. Perhaps this is just an extra property they have added?
In any case, since my application will primarily be used with e-mail attachments, I need a way for the phantom FileDrop to work, as stated above. I am unable to use Spy++. It doesn't seem to show any messages when drops occur.
Edit #2: Here is more information on how Gmail utilizes drag/drop for files: [URL]

I have a .NET login page. It works properly in Internet Explorer 7, but i want to make it compatible with Chrome, Mozilla and Safari.
The login code behind is:
Protected Sub btnLogin_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnLogin.Click
{..................
ScriptManager.RegisterStartupScript(Me, Me.GetType(), "test", "login()", True)
........}
The ASPX page code is:
function login()
{
if(document.getElementById("ctl00_Sidebar_Contentplaceholder_Lo1_SaveFlag").value =="Y")
[code]....
This is not working. I tried to debug it, but in debug mode the cursor only steps through the code behind. I'm not able to enter the javascript login() function on the aspx page.

I am creating a shell for a FORTRAN application which reads a tab delimited text file.Because I am using Excel to manipulate data, is it possible to use the Excel Automation features to "save as" a tab delimited text file?The only method available seems to be a unicode text format, which does not work. Or is there another format that mimics tab delimited so that the FORTRAN application will read such a file without difficulty?

I have an asp page with vb.net code that will query a database and present the user with the number of records that exist that need to be exported along with a button to export them. After you push the export button, it will prompt for a location and filename. But after that, it will not refresh the page with the new counts that now exist. Or in this case update the count to zero for the button they clicked.
[Code]
So how can I tell the page to refresh with the new counts. It almost seems like I need to tell the process to wait until after the user has finished finding the location and saving the file but I don't want to add a generic threading.thread.sleep in, I want it to only wait until they are done and then refresh the page.

I am working on a note taking application. I have got a treeview and a richtextbox. On the treeview note captions are organized in a hierarchy. When a tree node is clicked related note details are displayed in the richtextbox. I use an xml file to save and load the treeview state (including nodes, expand collapse state, image index etc). I want to include all the note details in this xml file as well. But I dont know how to save richtextformat into an xml file.
