System.ArgumentOutOfRangeException In Response.BinaryWrite()?
Oct 20, 2011
I'm developing a asp.net webforms website using vb.net. In that list of files displayed in a gridview as links, when clicked on a link it calls OpenFile method. This code I found on the web is used to download file stored in webserver to client, this works fine for images but when I try to download .docx or .xlsx file it gives an errorin the line "Response.BinaryWrite(btFile)", but downloads the file. Given below is shortend version of the actual code
I am using Visual Basic to dynamically create a Visio diagram. It is called from a web application. The web app makes the call to the .aspx file, which does its work and then writes the file to the web app through Response.BinaryWrite. The problem is this: there could be multiple users on the web app, and the VB app is currently confusing the web app with simultaneous use. That is, if two users both make a call to the VB app, the VB app doesn't separate the output, so one user gets a binary file (unreadable by Visio) with both users' contents, and the other user gets a blank Visio file. Can I use anything in the Response.AddHeader to distinguish the output so the Java code for the app can pick the correct output?
I keep getting an eroor this error says: An unhandled exception of type 'System.ArgumentOutOfRangeException' occurred in system.windows.forms.dll Additional information: Specified argument was out of the range of valid values.

When I try to debug this code. I got an error like this.
Module Module1 Public Declare Auto Sub mouse_event Lib "user32.dll" (ByVal dwFlags As Long, ByVal dx As Long, ByVal dy As Long, ByVal cButtons As Long, ByVal dwExtraInfo As Long)

It's about "System.Console.SetCursorPosition(130, 345)" how do i fix this?
It's something with "ArgumentOutOfRangeException was not unhandled".

I have that so far. It was working great for the names part until I attempted to do the level part, now i get the following error:
System.ArgumentOutOfRangeException: InvalidArgument=Value of '1' is not valid for 'index'.
Also at the line where i use a goto statement to go back to the beginning of the loop, is there any way i can do that without a goto statement? Like a second loop statement or something?
Note that Response.BufferOutput = false is set when the page first starts executing (well before the above code executes).The code is used to update a progress message while other threads execute long-running processes. One thread runs continuously and checks the status of the other threads. As the other threads finish, this thread outputs updated status messages to the end user. I realise that this could (should) be recoded using ajax, but it is a legacy app and that is not an option at the moment.
This code is run 10,000+ times a day, and the error only occurs about 5 times - so I suspect the response object is being blocked by other threads when the website gets busy. However, I don't know which performance counters to check in the performance monitor. Or is this problem caused by something else? I am using IIS 6, asp.net v2 and vb.net?
I am getting an ArgumentOutOfRangeException when I try to run the following code,[code]the table that is being read has a single row of data, the database and connection are fine as I can run INSERT/UPDATES etc but wherever I have used a datareader I am getting this exception each time on the "Using reader As MySqlDataReader" line.
I am trying to do an assignment for a programming class. The program works for items that are in the list boxes, but when I test one that is not (and a message box should then pop up) I get this error message instead.ArgumentOutOfRangeException was unhandled the InvalidArgument = Value of '5' is not valid for 'index'Parameter name = index
Here is my code...
Private Sub displayShippingButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles displayShippingButton.Click Dim isFound As Boolean
I was using vb6 for ADODB program with MS Access as database file. It was running fine with vb6.Later I upgraded the project to VB 2005 express edition. When I try to run the project, It load listview, retrieving data from Access file (MDB). It shows the error ArgumentOutOfRangeException error.This was my vb6 sql code to LoadListView.
Set objNewListItem = lvwCustomer.ListItems.Add(, , txtFirst.Text, , "Custs") PopulateListItem objNewListItem With objNewListItem

I have function on client side that get file, make a byte array from it and send that array to the web service on server!This is the function on client side:
I have an unbound DateTimePicker Control on a form. When the form loads the control shows 2005 - 01 as expected. I can use the arrow keys left and right to switch between highliting the year or the month. Pressing the up and down keys to change the month doesn't work an exception is raised. I don't understand why. I started a new project. Just added a DateTimePicker and the following code.
I have a dropdownlist with a list of options which is subject to change (e.g. 'active users'). Another data source may include historical data, but I wish to use the 'active users' dropdownlist against it. This means an ArgumentOutOfRangeException will be thrown so I want to catch that, and insert the required entry into the dropdownlist on the fly.
I've seen a few suggestions that point towards overriding the ondatabinding event within the dropdownlist, I've managed to do this insofar as I can create a static listitem for example "Value does not exist" and bypass the exception. However I wish rather than "Value does not exist" so show the actual value which we were attempting to find in the ddl.
ondatabinding is passed a standard EventArgs item which doesn't offer much to go on, I can see there is a DataListItemEventArgs class - is this in any way associated with a dropdownlist? I tried directcast on the EventArgs but that didn't work.
So is there any way - within ondatabinding - of finding out the value we're attempting to set on the dll, which causes the ArgumentOutOfRangeException?
I Was Coding A Tabbed Web Browser With A Progress Bar In Visual Basic 2010 Express Edition. I Started De-Bugging The Browser When It Pointed To This Sub: Private Sub Loading(ByVal sender As Object, ByVal e As Windows.Forms.WebBrowserProgressChangedEventArgs)
ToolStripProgressBar1.Maximum = e.MaximumProgress ToolStripProgressBar1.Value = e.CurrentProgress End Sub
And Showed This Error Message: ArgumentOutOfRangeException Was Unhandled By User Code Value of '-1' Is Not Valid For 'Value'. 'Value' Should Be Between 'Minimum' And 'Maximim'

i made a tcp/ip application using the .NET TcpListener class, my problem is that sometimes (about 30 / 4000) the connection between the client and the server got interrupted in the middle and the server response to the client is lost.is there a way to know if the server response was successfully sent to the client without the client response back?
I am trying to develop an authentication system and a way of which is making a user log in to my forums via my application this works great as I have a wonderful web coder helping me out but I also have the problem that if they log in correctly then it will display the webpage with the number 1 on it and if they log in but they don't have permissions to view it will not go to the correct and it will just go to the log in page.
I asked a question like this earlier this week, but I think I was way off basis, and I think I was getting help on the wrong subject. Let me explain the entire situation here, and I will be as detailed as Possible. I have developed an application for Windows Mobile Devices using Visual Basic 2008. One feature of the application, allows users to view records that are stored online, on the device.
I need help with something it drives me nuts. I have an application which send XML to a web server through a POST method. This part works excellent. But where I have issues is with receiving the standard response from the web server for OK or error. Instead of receiving the actual response, I get the error message" WebException was unhandled. The server committed a protocol violation. Section=ResponseStatusLine" . The response I should receive is in XML format where I have as elements the error result (ok or error), the error number and the error description. Here is the code I have:
this codes doesnt have any reponse from the database .. these codes is for case sensitivity of the usernametxtbox and if satisfied, the secretquestion textbox will automatically display the correct secret question.
Dim i As Integer Dim PassResult As String = "" Dim con As New OleDbConnection("Provider=Microsoft.ace.oledb.12.0;data
I've an application that's uploading data to a server. Occasionally the server returns a 403 response from a call to HttpWebRequest.GetRequestStream(). The response contains more data than simply the response code, but I can't figure out how to access it. Is there a way to do this?
I'm using Response.AppendHeader("Refresh", "2; url=default.aspx") To send users back to the home page after they log in or log out and it works. But, on the contact us page it fails and this is what it says: The resource cannot be found. Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.Requested URL: /default.aspx, 2; url=default.aspx The weird thing is this doesn't happen in debug, only on the live site. It looks like it's appending the header twice somehow...
how can i send a URL "https:[url].....without opening the web browser? and how do i get the response from it display it to my textbox? im using a vb 2008, can this possibly done?
I am posting to a website to get data back. The site returns it as an xml. I am able to get the data into a string. But what i really want to do is to have each item in the xml in a different string field.

I want to be able to split these fields and set them to different text boxes on the page.
Code: Private Function web_scan(ByVal code As String) As String Dim myReg As Net.HttpWebRequest = _ DirectCast(Net.WebRequest.Create(ServerSelect.Text & "/scanner.php?code=" & code), _
