I'm using AsyncFileUpload for uploading files, before saving file on server, i rename the selected file. How can I get this new file name in the client side?
<asp:AsyncFileUpload ID="AsyncFileUpload1" runat="server"
OnUploadedComplete ="UploadFile1"
OnClientUploadComplete="uploadComplete" ThrobberID="myThrobber" />

I am using ASP.NET 3.5. When the user click on say btnSubmit I want to first execute some JavaScript code and then execute some C#/VB.NET code.
Is this possible? If so how would one do it?
I am currently using the AsyncFileUpload in my VB.NET web app. Locally it works perfectly, however on the server it fails to upload a small file (<9k). I can't even seem to debug this as in JavaScript handlers I have no idea as to how to get the error reason.
function uploadError(sender,args) {
$get("<%=LabelErr.ClientID%>").innerHTML = "Unable to Upload file for the following reason: ", "<span style='color:red;'>" + args.get_errorMessage() + "</span>";

I have an asp.net form which contains a dropdownlist which posts back to the server on change and populates second dropdownlist with some dates.
The form also contains other fields some of which are validated clientside and some server side.
Here's the problem I'm having. If I get a clientside validation error then try to change the dropdownlist, the second dropdown does not get populated. If I then change the first dropdownlist again, it works as expected.
Here's my submit button:
<asp:Button ID="btnSubmit" Text="Submit" runat="server" OnClientClick="Page_ClientValidate(); return checkPassengers();" OnClick="Page_Transfer" ValidationGroup="FormSubmit" />

When i click on the div it does not execute the ServerSide Code ...why?
incorrect technical words used, I'm new to AJAX/Jquery.I have a function with AJAX in it. It is supossed to execute a serverside function, but it doesn't do anything. I have checked my code multiple times. I use similar code in a different location, and that one works fine.Here is the function with AJAX:
function pass_on() {
hide_div("#outer_layout", 500);
get_din();

I'm using the chat program provided in the 101 examples kit, and have modified it a bit to suit an app i'm fooling around with. I have come across a problem...
When the client side crashes, the server side doesnt realize that the connection has been lost. Is there any way for the server to poll its clients table to figure out which streams are still open?
I recently updated an app that I wrote to allow the clients to run the app in read only mode disconnected from the database by serializing the typed dataset, and when they are offsite/offline instead of connecting to the database the serialized dataset is loaded. This has been working great and then I hit a major snag.
A majority of the graphs and reports are based on sql views that are typed views in the dataset. Of course offlline the tableadapters cannot run the sql views.
Does anyone know a way to run/fill the view with the already loaded dataset? I can add rows clientside so I'm inclined to believe there must be some way to fill the view clientside but I've been at this for a number of hours now and not making any real progress.
Quick query...I'm trying to scan a long string and return any values that occur between the tags <FileName> and </FileName> I've got a bit of code here to use regular expressions to return the position of the occurunces of both substrings..Just wanted to find out if there is any way to scan for both substrings within one loop (as im currently doing 2, one for the first substring and one for the 2nd) so I can use something along these lines:
ringlist = Mid(XMLRESP, (startloc + 1), (endloc - 1))
MsgBox(ringlist)
to msg box the value between the substrings...either that or another approach to return the value between the 2 substrings (it can be of variable length)
Dim patternstart As String = "<FileName>"
Dim patternend As String = "</FileName>"
Dim matchesstart As MatchCollection = Regex.Matches(XMLRESP, patternstart)
[code].....
How would I do that? Sample code is below that demonstrated that the file I opened contained the full path and file name.
I want to extract just the path and serialize that to the user.config file as a UserSetting value. Then next time the user opens the dialog box, it uses that saved path string to go immediately to the location previously used.
If openFileDialog1.ShowDialog() = DialogResult.OK Then
Properties.Settings.Default.persistConnectionType = openFileDialog1.FileName

I don't know why calling another function inside the OnUploadedComplete does not work in ordinary way, It's my code:
ASP.NET code:
<asp:AsyncFileUpload ID="AsyncFileUpload1" runat="server"
OnUploadedComplete ="UploadFile1"
OnClientUploadComplete="uploadComplete" ThrobberID="myThrobber"
onclientuploaderror="uploadError" CompleteBackColor="White" />
VB.NET code:
Protected Sub UploadFile1(ByVal sender As Object, ByVal e As System.EventArgs)
'saveing file on disk, this part works fine, but calling
'myfunction() does not work properly

I have a Listview on my form with different files. I can selet a file en open it with the proces start method. To open the file i use the OpenFileDialog method and select the filename. This work very good. With the code below.
My question is if there is a method to get the selected file without using the OpenFileDialog Box. So when i dubbelclick the selected file the proces will start with open the selected file. Something like:
proc.StartInfo.FileName = Me.SelectedCell.FileName
instead of proc.StartInfo.FileName = Me.OpenFileDialog1.FileName
PS) May be i can preduce the Filename using the OpenFileDialog method on the background.
Private Sub ListView1_MouseDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListView1.MouseDoubleClick
If Me.OpenFileDialog1.ShowDialog() = Windows.Forms.DialogResult.OK Then

I recently came across the AsyncFileUpload control in the latest (3.0.40412) release of the ASP.Net Ajax Control Toolkit. There appears to be an issue when using it in a hidden control that is later revealed, such as a <div> tag with visible=false.
Example:
Page code -
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="act" %>
[Code].....
I have a breakpoint on the UploadedComplete event but it never fires. However, if you take the AsyncFileUpload control out of the <div>, making it visible at initial page render, the control works as expected.
So, is this a bug within the AsynchUploadControl, or am I not grasping a fundamental concept (which happens regularly)?
I would like to restrict what they see in the file upload dialog, which is set to "All Files" by default. I understand how to validate that they only uploaded a certain file type, that is not the question here. I would just like to know how to default the file type in the file selection dialog.
Is there any way to change this to "PNG only" or "*.png"?

I'm trying to figure out how to get the file name of the application at run time, in case it gets renamed.Also, as a easter-egg. First post, I don't know what code to put but this is how I am so far, the {FN} is where I need the file name.
If({FN} = "easter.exe") Then
msgbox("You found a easteregg! :O")
end
I often use things like the crosshatch in filenames to group them together. Until recently this has not been a problem.
I am working modifing a WPF app which uses a Listbox to store images. I need the full path of the image to feed to a class to retrieve metadata.
The test image is named "# Canon-ixus.jpg".
Using Listbox.SelectedValue to return the filename I get "%23 Canon-ixus.jpg". There are not a whole lot of options to returning the name of the selected item from the Listbox.
Is there any simple way to get the name back to its original form?

I have a directory with more then 350.000 files in. I need to process every single file and move them to an other folder. When I use the dir() method it takes a few seconds before if it returns the first file found.
dim foundfile as string = dir("d:")
In the documentation there is this:
"The My.Computer.FileSystem Object gives you greater productivity and performance in file I/O operations than the Dir function. See My.Computer.FileSystem.GetDirectoryInfo Method for more information."
But I can't find any method that is faster then dir, and gives the same result. I can't use this method below because it takes for ever to load......
For Each foundFile As String In My.Computer.FileSystem.GetFiles("D:")
Next
It just does not work fast...
When I use the Dir() method it takes like 5 sec, and it uses 100% cpu... it is just not a option. How do I get the same function as the dir method but better performance? (I use visual basic 2008).

In the XP SaveFileDialog, the user is allowed to set the SaveFileDialog.FileName.
I'm using Vista operating system and am using the VistaBridgeLibrary.dll so that I can get the Vista version of the Dialog Boxes. With the CommonSaveFileDialog (for Vista dialog), I'm unable to set the FileName property since it's read only.
Is there a way to populate the FileName so that when the DialogBox displays the filename in use is displayed?
There is no editor available for '<filename>'.Make sure the application for the file type (.vb) is installed.I got this message after I updated a VB08 project to VB10. I tried to open a form when this message was shown. It happens to every form in the group (but not standard classes).
