Visual Basic

What!? #1.) There should not be a problem as long as your MDI Form's "MDIContainer" Property = True. #2.) You can't

First, VB doesn't use wild cards comparing strings. It also doesn't do regular expressions natively. You could use a third party regular expression control like the Regular Expression Library (http://download.com.com/3000-2070-5588590.html?tag=lst-4-10) to validate the input. The other option would be to build another string by scanning the input string and replacing each number with a # character and each letter with a % character. Then your code snippet would work.

Thanks for this.. Very impressed with the nBass assembly. I have loaded the relevant file into a stream object, but don't know how to analyse the level within the stream.. Should I be looking at GetData(buf, 0) method? Graham

There are several ways: the simplest form is creating a COM DLL. Not too easy for a newbie, though. dazinith wrote: im also considering switching to c#, is it easier to write dlls in c# that to learn how to in c++? Yes, much simpler: You only need to create a library project, create a class, and in project properties, you set "Register for COM interop" as true. Your DLL is now ready to go in VB 6. There are step-by-step tutorials about this on CP which show how to do this in greater detail, but this is the general procedure.

hi.. what do u mean with (Extract required information ):confused: ?? anyway you can use IE control and use its dhtml object model to retrieve the document elements (all anchors for example if you're making a web spider)

Thanks. I have set an isdirty flag as a boolean. What i was looking for was an event for the textbox to detect the change which was the textchanged event. Everytime one of these events gets invoked, isdirty is set to true. This works for me so thank you very much for your help. :)

I would make the second array an ArrayList. Dim origArray() As String = {"a", "b", "c", "d", "e", "f", "m", "z", "l"} Dim secondArray As ArrayList = New ArrayList() Dim i As Integer = 0 For i = 0 To (origArray.Length - 1) Select Case origArray(i) Case "a", "m", "l" secondArray.Add(origArray(i).ToString) Case Else End Select Next Paul Watson wrote: "At the end of the day it is what you produce that counts, not how many doctorates you have on the wall."

Thanks for the reply, maybe I wasnt too clear on my original statement. Its not that I want to handle each event seperately, it was that, I did not know how 1) make a sub handle more than one event and 2) how you do this when creating a thread from scratch. As it happens I found some thing on another site last night that showed me all I needed, I now understand a little more about dynamically creating objects and hooking things up to them etc. I did say that I was a newbie to all this:-D. I'll include what I found just in case anyone else is interested 1) you can say Sub TermEventHandler (ByVal intResult as Integer) Handles specific_instance.TermEvent anotherinstance.Termevent ... 2) To hook up the event dynamically AddHandler specific_instance.TermEvent, Addressof TermEventHandler

If I'm following you correctly, what you're wanting to do is capture the delete keypress for the datagrid. The only useful way I've found for doing this is to inherit your own datagrid and then override PreProcessMessage to check for the delete key. I use this to confirm deletion before actually carrying it out. The class looks something like this: Public Class DataGridConfirm > Inherits DataGrid Public Overrides Function PreProcessMessage(ByRef msg As System.Windows.Forms.Message) As Boolean > > > Dim keyCode As Keys = CType((msg.WParam.ToInt32 And Keys.KeyCode), Keys) ' If this is a "KeyDown" message and the key pressed was "Delete" ' then we need to verify that the user actually wants to delete ' the record by presenting a messagebox ' Win32.Msg.WM_KEYDOWN just points to an Enum: WM_KEYDOWN=&H100 If msg.Msg = Win32.Msg.WM_KEYDOWN And keyCode = Keys.Delete Then > > > > > If ((MessageBox.Show("Are you sure you want to delete?", "AppTitle", _ MessageBoxButtons.YesNo)) = DialogResult.No) Then ' They've selected no, so simply return Return True End If > > > > End If ' If the user has not canceled the request, flow into the normal ' message processing of the base control Return MyBase.PreProcessMessage(msg) > > End Function End Class After creating this class, just substitute it for the regular DataGrid your currently using. Hope that helps!

Hi all I've created a solution for this problem, for who is intrested, you can find it here: http://www.codeproject.com/useritems/LeaditWebServiceWrapper.asp. Jan

Hi Daniel...Thanks for the reply to my post. I can either put the code in a reply or email it to you if you're curious - I ask because it is a couple thousand lines of code generated by the data wizard. If you had a suggestion of what specifically to look for, I could copy and paste it to a reply. On another note, do you know if you can 'update' (uses a merge I believe) more than one row at a time? Again thanks. Mike Thanks, Mike
