You'll probably want to set Button.Visible = False while the form is small. That way the user can't tab to the button or press ALT-[Key] to activate it.

I'm tryingto read in a small xml file into a xmldocument which I will then get the needed information from. Below is my code. I can't get past doc.loadxml... I think I'm not using the right reader. I was hoping to read the entire file in so it looks like a long string to loadxml. Can anyone provide any help?
Dim doc As Xml.XmlDocument = New Xml.XmlDocument
Dim reader As New Xml.XmlTextReader("c:\test.xml")
Try
doc.LoadXml(reader.Read)
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try
reader.Close()
Dim account_number As Xml.XmlNodeList = doc.GetElementsByTagName("account_number")
Dim reply_code As Xml.XmlNodeList = doc.GetElementsByTagName("reply_code")
Dim sequence_number As Xml.XmlNodeList = doc.GetElementsByTagName("sequence_number")
MessageBox.Show(account_number(0).InnerText)
MessageBox.Show(reply_code(0).InnerText)
MessageBox.Show(sequence_number(0).InnerText)
Dim writer As New Xml.XmlTextWriter("c:\test.xml", Nothing)
writer.Formatting = Xml.Formatting.Indented
doc.Save(writer)
writer.Close()

Don't use a reader just load the file directly into the XmlDocument object
dim doc as new XmlDocument
doc.LoadXml("c:\test.xml")
|
|
|
|
|
I don't know why I didn't do that first but even with it like that I get "The data at the root level is invalid. Line 1, position 1."
here's my xml file:
<request>
<sequence_number>000002</sequence_number>
<account_number>103363463355</account_number>
<reply_code>201</reply_code>
</request>

Thanks to everyone for their help.
I found the answer finally at http://www.bdragon.com/lair/2005/08/27_xmlexception_the_data_at_th/
it's doc.load("c:\test.xml") and not doc.LoadXml("c:\test.xml")
Thanks to everyone for their help.

When Setting TrustLevel for Remoting Application for Server as well as for the client, by following command,
Dim SProvider As IServerChannelSinkProvider
Dim CProvider As IClientChannelSinkProvider
SProvider = New BinaryServerFormatterSinkProvider()
CProvider = New BinaryClientFormatterSinkProvider()
CType(SProvider, BinaryServerFormatterSinkProvider).TypeFilterLevel = TypeFilterLevel.Full
chan = New TcpChannel(props, CProvider, SProvider)
I get an an error in the second last line. And when i comment it run run the serverand the client i get an error
like this:
""This remoting proxy has no channel sink
which means either the server has no registered server channels that are listening, or this application has no suitable client channel to talk to the server.""
I have also read that all the remote application has Trustlevel =low ByDefault.
Help me out!!!

1 - Develop a function to translate a color name to color code:
White #FFFFFF
RED #FF0000
GREEN #00FF00
Blue #0000FF
2- When web browser send data to web server using the URL, It encode all character by place the percentage symbol(%) and two hexadecimal digits, It also converts the space character to (+) symbol
for example the text "Abc-2&3" will be encode as "Abc%2d2%236"
Develop a function to decode a string send by the web browser.

What specifically is is that you have problems with?
What are you studying currently? What techniques are you supposed to use in these execises? Most of the first task and the entire second task can be solved by using built-in methods in the framework, but I suppose that this is not the intention of the exercises?

Hello
You have to reference the System.Drawing library
Then in top of your class insert:
Imports System.Drawing
That's it
|
|
|
|
|
yes that's good!

hi
It is working in vb.net but not in vb6.0 because in vb 6.0 there is no any class like bitmap in system.drawing.dll.
if you have any other idea so please!
Thanks

The simplest way in vb6 is to add aninvisible picture box and do the following to load the picture and obtain the height width
PicBox.Picture = LoadPicture("C:\1.jpg")
PicBox.AutoSize = True
MsgBox PicBox.Width
MsgBox PicBox.Height
Me.Show
"If i was king cigarettes would be free."

Frenz,
In my current project, I have some problems with printing. i.e.,
Print Preview is perfect but "Printable text is invisable on Printout"
briefly: I defined a method for draw a string in a rectangle box. there after I called this method in a while loop to print severaltimes by separating with a line on my printdocument. when I check preview of the print document, that is in perfect way. but in printout doesn't have a text within a rectangle boxex.
I don't know exactly what is the problem? plz solve it if possiable.
wish me as All The BEST.

Hi Guys, I am working on VB.NET/Access. Consider the data 0000011. I am writing the data in CSV format to a file. When I open the file with notepad, the data looks correct. However, when I open in excel, the leading zeros are truncated. It appears as a number.
how do you write such data to open correctly in excel.
With Best Regards,
Mayur

You need to convert the cell to 'Text' format and not 'General'. By default excel will automatically exclude leading Zero's in a 'General' Formatted Cell!
Highlight the whole column and right click, select 'Format cells' and change the format to 'Text'.
Hope this helps.

Even if I convert the cell to TEXT, the result is the same.

It Will be!
You need to use the import wizard in excel and select the cell type to be text.
If you load the file then try changing the column to text it will not do anything, as the leading zero's have already been taken out.
