I am hoping this is not for your homework, but, I will answer nonetheless. Two simple ways to accomplish this would be: 1. Declare your method in Form1 as static and invoke it from Form2 like so: In Form1...

 public static void Hola()
 {
      MessageBox.Show("Hello");
 }

In Form2...

 public void InvokeMessage()
 {
      Form1.Hola();
 }

2. Using your declaration like so: In Form2...

 public void InvokeMessage()
 {
      // "using" so Form1 is disposed at end of method.
      using(Form1 otherForm = new Form1())
      {
           otherForm.Hola();
      }
 }

Try using double quoutes like so: str = Replace(str,"

Thanks to Christian and Guffa. Below is the solution I was able to come up with...

Public Structure HexReplacement
Public HexCharacter As Char
Public Replacement As String
End Structure

Public Shared Function ConvertHexToChar(ByVal hexValue As String) As Char
Dim convertedChar As Char = Nothing
Try
convertedChar = Chr(Int32.Parse(hexValue, Globalization.NumberStyles.HexNumber))
Catch ex As FormatException
' Error handling here....
Catch ex As ArgumentException
' Error handling here....
End Try
Return convertedChar
End Function

Public Function CleanOutHexValues(ByVal dirtyString As String, ByVal hexReplacements As HexReplacement()) As String
Dim cleanString As String = dirtyString
For Each hr As HexReplacement In hexReplacements
cleanString = cleanString.Replace(hr.HexCharacter, hr.Replacement)
Next
Return cleanString
End Function

Public Sub TestHexCharCleanUp()
Dim hr(1) As HexReplacement
hr(0).HexCharacter = ConvertHexToChar("0b") ' "0b" =  or single space.
hr(0).Replacement = ""
Dim dirtyString As String = "Testing the removal of  "
MsgBox(CleanOutHexValues(dirtyString, hr))
End Sub

Comments will be greatly appreciated. :)

Can someone help me with the following: 1- I have xml text data that i need to take out invalid characters from. 2- this data contains extraneous characters that i need removed in order to use xmlDocument.LoadXml(str) 3- when this characters are in the str variable i get an XmlException that indicates that there's an invalid character with hex value of 0x0B. 4- how can i remove that character from the string prior to loading it in with xmlDocument.LoadXml(str)? 5- i am using VS2005 Your help is greatly appreciated....:confused: -- modified at 23:11 Thursday 17th August, 2006

Try the following with your function: Public Function GetAllChangeControl() As String Dim con As OleDbConnection Dim cmd As OleDbCommand = New OleDbCommand con = New OleDbConnection(connectionstring) cmd.Connection = con cmd.CommandText = "EXECUTE GetAllChangeControl" con.Open() '--------------------------------------------- ' Here is the change Dim retVal As Object Try retVal = cmd.ExecuteScalar() If Not(IsNothing(retVal)) Then Return Cstr(retVal) Else Return String.Empty End If Catch ex As OledbException Throw ex Finally con.Close() If Not con Is Nothing Then con.Dispose If Not cmd Is Nothing Then cmd.Dispose End Try '------------------------------------------ End Function Let me explain, it is possible that your "cmd.ExecuteScalar" is not returning anything and you are not checking for that, so what I've done here is do a simple check and return the appropriate value. I have also enclosed the procedure in a Try statement to capture the Exception, and make sure that even if an Exception is thrown, the connection is closed and you realease your resources. I hope this helps.

Yes I'd love to see what you have so far, and maybe I can be of some assistance. I'm always looking for new challenges. Also, I have been looking for an excuse to use VS.Net 2005, but I have been a bit lazy and out of ideas. (Too many brain cells used at my real job. lol)

Looks good. I'm just glad to have been of some guidance.:) What exactly are you building, if you don't mind my asking? I sounds like a Notepad substitute, if it is, I like the tabbed approach.

Try the following: For Each tabCtl As TabPage In TabControl1.TabPages For Each ctl As Control In tabCtl.Controls If TypeOf ctl Is RichTextBox Then ' Code to save the contents.... End If Next Next Hope this helps.

Here's a somewhat reference page that might be helpful. http://www.harding.edu/USER/fmccown/WWW/vbnet_csharp_comparison.html[^]

I noticed a bug with using ShowDialog to display a custom dialog box, and then using ShowDialog from that custom dialog to display a FolderBrowserDialog. The problem is when I select "Ok" or "Cancel" on the FolderBrowserDialog, both dialog boxes disapear. Has anyone else run into this problem? And if you have, have you been able to get around it? Thanks in advance.

Thanks everyone for your help! I ended up using the following statement: WHERE (UPPER(field7) = 'WORK ORDER') AND (field14 BETWEEN @startdate AND @enddate) Following airbus' suggestion to use UPPER, and documentation I found in SQL Sever Bible Thanks again!

Rob thanks for your quick response! Yes it is MSSQL 2000. Now please pardon my ignorance, but, if I have records with dates greater than 9/1/05, the following statement should return all those records rigt? SELECT field7, field13, field14 FROM myTable WHERE (CAST(field14 AS Datetime) >= '2005-09-01') AND (field7 = 'Work Order') But my result set is empty. What am I missing?

Hi everyone, I am attempting to read records from a table based on a date range, however, the dates are stored in a varchar field. The format of the date is 2005-09-01 10:50:00. How can I get around the fact that the vendor used the wrong data type? Your help is greatly appreciated.

I was wondering if anyone out there knows of an algorithm to generate unique alpha-numeric keys for database use.

Here is a quick and dirty way of checking for a process. First you need a reference to the SystemDiagnostics. Imports System.Diagnostics Then Dim myProcess As Process() = Process.GetProcessesByName("ProcessName") If myProcess.Length > 1 Then MsgBox("You can only have one instance of this application running.") End If Hope this helps :-)
