I am attempting to send my XML file through an API. I have done this no problem by using the below code, however when I try and send the FILE over it will not work, I am now getting in the browser:
Data at the root level is invalid. Line 1, position 39.
Without trying to send FILE it works:
' create the Xml that the Msxml2.serverXmlHttp object will send to the Webservice
dim Xml_to_Send
Xml_to_Send = "<?xml version=""1.0"" encoding=""utf-8"" ?>"
Xml_to_Send = Xml_to_Send & "<xmldata>"

Here is my problem: I developed one application in VB.Net in VS 2008 Express Edition on MS Vista. I published the application and created the installation setup. Now when I install this application on any Vista machine, it runs without any problems, but if I install it on an XP machine, the installation is clean, but when I launch the application, it ends abruptly without any warnings/error just after the splash screen.
Then to investigate further what I did was that I copied the source project from my VS 2008 Express Edition on Vista to an XP machine having full (VS 2008 Team System) version , and when I try to compile it there (XP/VS2008 Full), I get one error in one of the forms resx file. Incidently this is the same form that gets loaded after the splash screen. So I see there is some correlation between my application ending just after the splash screen and failing to compile the main form of the application. The error that I get reads like: "Invalid resx file. The parameter is incorrect Line 1374, position 5."

I have a procedure that should produce a valid UTF8 string or file. But I must do something wrong as IE show the following error when I try to open the file in it:"Invalid at the top level of the document. Error processing resource 'file:///C:/TEMP/test.xml'. Line 1, Position 1"Below you'll find the code example.NB: The code example is in VB but I can also handle C#; that's why I've added the C# tag also.
Dim sfpXML As String = "C:TempTest.xml"
Dim msXML As New IO.MemoryStream
Dim xmlWriter As System.Xml.XmlWriter = Nothing

The Form Designer in the IDE is no longer working properly. When I create a new project, the Form Designer will work, but after I save it and close the IDE and reopen the next day the Form Designer no longer shows the form and instead says "To prevent possible data loss before loading the designer, the following errors must be resolved: An Error occurred while parsing EntityName.Line 2, position 62" If I click ignore and continue, then it just displays a blank form with no controls. The problem appears to have started after I unistalled and reinstalled VB2008 Express.

Ypos = TopMargin + Count * PrintFont.GetHeight(ev.Graphics)
ev.Graphics.DrawString(ROData(x, 3), PrintFont, Brushes.Black, LeftMargin, Ypos, New StringFormat())
Count = Count + CInt(ROData(x, 4))
The above line prints the data contents of the ROData array in position three. I would like to be able to assign a specific position accross the line to have the printer print the data at without left padding the array data.

I am trying to create a program that downloads audio files via FTP, converts the audio to mp2 if necessary and copies them to a certain directory for consumption by our automation system. (I am a radio station engineer.)I am using the open source converter FFMpeg to convert audio files to mp2. This is a command line exectuted program. Here is the command line that I use to execute the external program with the input and output audio files at the root level: cmd.exe /k ""C:New Folderffmpeg.exe" -i "C:Test.mp3" -y "C:Test.mp2"" This command line works correctly whether I am using Shell() or System.Diagnostics.Process (Process) to execute the external program. I am going the Process route so I can know when the conversion has finished.Now, I really don't want to use the root directory for this but when I go below root with this line using Process the external program will not execute:[code]Can anyone tell me why that line will not work with Process though it works as expected with Shell()? I can't figure out how to stop the external program to get some feedback as to what its problem is.

Much to my disappointment I recently discovered that VB can not calculate the cube root (or any odd root) of a negative number even though it is a real answer.For instance if you tryMsgBox((-1)^(1/3))You should get -1 because -1*-1*-1 = -1. But no, VB will return NaN, not a number.Anyways, my problem is that I'm making a graph program and the user needs to be allowed to enter any formula they want and have it evaluated so the program can graph it. But if the user enters anything with x^(1/3) or like it, it will fail.So I was wondering if anyone knows of a way around this problem, such as an extension or patch or something that will fix the issue in Visual Basic. I haven't tried VB 2010 but does anyone know if they have they fixed it yet in that version?

I'm reading a text file with StreamReader, line by line. If a condition is met, then I do an operation and then start reading the file again from the first line. I realize I could close and then re-open the file, but surely this would be very slow.
I could do this easily in VB6, but pulling my hair out trying to do this in vB.net. It seems that 'Seek' is the function to use, but it doesn't work.
I've seen other examples, where it works, but you must open it a different way -- with a file number.

I'm trying to make a very simple Silverlight application.I want it to be full-screen, and I want to draw a line onto a Canvas.My problem is that the .Width and .Height of the canvas never seem to have a valid value. The website shows the canvas at 400x300 pixels or so, and when you click on it, it goes into Fullscreen mode.I want to use the Height and Width to find the usable space of the screen. I've tried adding events (thinking that the canvas wasn't yet ready to be used immediate after the full-screen line of code) but the LayoutChanged and Resized events don't seem to yield anything.

I'm writing a text editor for my own use ( I'm "home learning") where I want to be able to leave comments for myself, like in code section of the VB express IDE. I have figured out how to get the Integer Location of the apostrophy, but can't get it to color the rest of the line. I don't know how to tell the program to find the integer value of the last character in the line. I need that to be able to subtract the apostrophy's location from the last character's location, to get the "SelectedLength". Then I can add that to the apstrophy's location to give the SelectedLength the SelectionColor.This code was thrown together from excerpts of several codes I found on the web. I had to rewrite everything to get it to do what it does so far...
Apostrophy Location is char # 534 , the end of the line is 547. ( I cheated to get that count by placing another apostrophy there, and reclicking the btn. )Anyway, I want to take 547 - 534 to get (13) the SelectionLength, then give the SelectionColor ( green) to that selected text.

Dim Location As Integer
Dim char3() As String = {"'"}
Dim z As Integer = CStr(vbCrLf.Count)

When I right click in a richtextbox, a context menu appears with an option 'get line'. When that is pressed, it should return the line number in which the mouse cursor is in.
I was thinking something like:

Dim intLine As Integer

I'm testing a small program that can read & write to an rtf file. Examples I have found work fine, although I have two questions:
1)If I need to ALWAYS write to line number 9 of an existing RTF file, do I need to "read" 9 times or can I immediately position myself to line number 9. I have found character manipulation but can't seem to find what I need with positioning to a particular line number.
2)BOLD text: I have found examples where I should be able to format my text, such as
MyFile.WriteLine ""
MyFile.WriteLine Text
MyFile.WriteLine "0"
but when doing this, it does not "bold" my text, but actually prints the text exactly as shown. I'm looking for information/links that I can "bold" "Italicize" text. Code is written in VS2005.

I have an application in VB.NET which gets string data from the database. This string has data which looks as below:
"This is the update: I have an issue with the application"
I need only part of the data, that comes after the new line i.e. "I have an issue with the application".
For this I am trying to search the position using InStr where the string has data in a new line. I tried many options, but they don't work.
I used "vbCrLf", Chr(13), "
", "
", "<br/>", Environment.NewLine, but none of them work.
How can I get the data I need?
