Same here, and have picked up on it relatively quickly. For future reference, put your code inside the code block or inline code tags at the bottom of the reply form. It makes it easier to read

At least you are not dealing with passing xml right now like I am trying to do. My case works sort of okay but even though I am returning XmlDocument, my test app is looking for XmlElement. Now, set aside my banter, back to your problem....
Dim strUrl As String = "http://localhost:5404/CoolService/Service.asmx", I took out CoolService, and left it as Dim strUrl As String = "http://localhost:5404/Service.asmx" and it looks like it worked.

Wow...thats great! Actually I need to pass an xmlDoc and receive an ID in response to it from the webservice. But what I am thinking is, if I get this simple one to work...we can definetely replace the strings with whatever we want. Am I making sense?
Can you please discuss more on making asynchronous calls?

It's not that tough actually.

I've stuck with just invoking the method, here is what I've done, minus any client intellectual property...
<webmethod()> _
Public Function GetContact(ByVal contactID As Integer) As XmlDocument
Dim ContactDataSet As New ContactDataSet
Dim ContactDataAdapter As New ContactDataSetTableAdapters.ContactTableAdapter
ContactDataAdapter.FillByID(ContactDataSet.ContactTable, contactID)
Dim memStream As New System.IO.MemoryStream
Dim xml As New XmlTextWriter(memStream, System.Text.Encoding.UTF8)
ContactDataSet.ContactTable.WriteXml(xml)
Dim myXDoc As New XmlDocument()
memStream.Flush()
memStream.Position = 0
myXDoc.Load(memStream)
Return myXDoc
End Function
It very happily gags up the correct data.

Well, disregard my latest post, it only gave back the entire http response. You may have to hand pick out the returned value out of the http response, perhaps through regular expressions.

I am automating excel and would like to align the lefts of my VB.NET form and Excel application. Unfortunately, the "left" in Excel is on a different scale than the "left" of the windows forms. I would like to use code like:
Me.Left = oApp.Left
where oApp refers to the Excel application. This, however, fails to left align these windows. I think I'm missing the big picture here. Anyone have any suggestions? Thanks!

Yep, you're missing it alright. The Left in the Excel.Application class is not in pixels, but in points. Documentation on Left[^]...
|
|
|
|
|
I see... So that means there isn't a good way to do what I want to do?

erhmmm converting points to pixels or if it's out of hand using the old fashion GetWindowEx and GetWindowRect from the Win32 API.
An aproximation is 1.3 ... so for let's say 3 points u have about 3,9 pixels.
|
|
|
|

I didn't say that. It just means you have to use a different method to get the window rectangle. Use the Process class to find the EXCEL process, the get it's MainWindowHandle. You can then use that handle to call Win32's GetWindowRect function (see www.pinvoke.net for examples) to get the Left position in pixels.

Good afternoon!
Currently i'm working with .Net Framework 2.0 SerialPort Class and trying to send a bunch of bytes as a command to obtain data from a remote system.
The GSM connection is well done, but after this connection, i'm sending a command regarding the communication protocol of the remote equipment, but i don't get any kind of response.
Could anyone help me with this? I'm sending the code i've wrote:
Option Explicit On
Option Strict Off

'.NewLine = Chr(13) 'CR - Carriage Return

End With
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

spObject.Close()

spObject.Open()

Catch ex As Exception

Try

End With
Catch ex As Exception

Return
End Try
Try

Catch ex As Exception
RichTextBox1.Clear()
Button3.BackColor = Color.Silver
RichTextBox1.Text = "It wasn't possible to close this application! Please try again."

End Try
End Sub

There are 3 glaring possibilities. The first is you have to make asolutely sure your communication parameters are correct, like baud rate, data bits, stop bits, parity, ....
The second is that you're call to spObject.ReadLine will only work if the device sent back what .NET interprets as a Newline[^] sequence in the byte stream. If this sequence isn't there, then the call will throw a Timeout exception.
The third possibility is that you didn't send the command to the device in a manner, or format, the device expects. Is the byte sequence correct?? Is the command terminated correctly?? Was it sent with extra bytes appended to it that the device didn't expect (like CR and LF)??
This is going to be a difficult question to answer because YOU have the hardware, not us. We have nothing to test this against. It's going to take a bunch of research on the device and trial-and-error fiddling on your part to get this to work.

Very good answer by Dave Kreskowiak
first check from the hyperterminal to check your sending protocal is correct,
after u got response then look through your code for bugs.
don't use the spobject.readline , this statement will not accept the extended ascii chart characters. use spobject.readbytes

Hi,
I have a string in which I have to replace all occurances of special characters with null string or character. Trim(Char[]) function is trimming only start and end of the string but I need to Trim the complete string between also.
Can anybody please help me.
Thanks
Aleem Mohammad.

Use replace instead of trim.
Dim line As String = "abc#$*xyz"
line = Replace(line, "#$*", "")
Any suggestions, ideas, or 'constructive criticism' are always welcome.

Hi,
Good Idea but I one problem with this, the sequence of special characters is not known and wherever any special character appears that should be replaced with null string.
string may come like this and even in different way.
"asfgd%dfg&sdfd@#$sfdgfg&fdgfd*fgfdg$%$%$rtee&*were$^&^&dfds43636"
So any idea please will be a great helpfull.
Thanks a Lot,
Aleem Mohammad.

You could think it a lil bit different ... just a thought
use System.Text.RegularExpressions.Regex with a negated class
something like "[^a-z0-9_]" where the group represents negated valid characters(meaning anything that is not there between those [] brackets will be matched) and use System.Text.RegularExpressions.Regex.Replace("your incoming string","string to replace the occurences of invalid chars");
|
|
|
|

Hi,
Good Idear but can u please help me by giving a small code snippet if possible.
And can u please atleast hint me how to show the negation expression in a RegularExpression. That would help me a lot.
Thanks,
Aleem Mohammad.
Thanks & Regards,

dim myString as string = "my incoming string"
Dim reg as new System.Text.RegularExpressions.Regex("[^a-z0-9_]", System.Text.RegularExpressions.RegexOptions.IgnoreCase)
dim resultString as String = reg.replace(myString,"")

Hi,
Thanks for the help but only one final question I may need to use the special character Space as I am going to use the string for Directory name, can u please give me idea how to mention spaces in regular expression.
Thanks,
Aleem Mohammad.

Look at the bright side ... at least you won't get another regex question ... at least not today :P
|
|
|
|

Another RegEx would do this easily. All you have to do is match any character that is not acceptable and call the Replace method on the RegEx object. The match would probably be something like "\W" and the replacement string would be an empty string.
Google for "Expresso RegEx" and you'll come up with a very nice tool to help you with this.

I think we are in standby mode for the next regex question today
