Hi There
You have to create instance of the form and then call the methods. If the form is Form1 it should be some what like this
F1 as Form1
F1.Show
F1.Hide

Hy everyone!
I want to do some stringparsing, but well I seem to having done to much programming in C# and C/C++. So I guess I start mixing things.
So what I want to do is the following:
I do have an input in an Excel Cell which looks like "xxx-yyyy" or maybe even blanks between them like "xxx - yyy" etc. xxx and yyy represent integers. So now I do want to split this string to get xxx and yyy in seperate integer variables. Well I guess it is quit simple, but at the moment I seem to be mixing things. I know how to do this in C# etc (parsing the array of char) but well...
the info I collected from the sheet is stored in a variant variable, because the user should be allowed to either enter "xxx" or "xxx-yyy".
Thanks for your help.
Stephan.

I just found out myself. I have to use the Split(string) operation but is there any way to split the string without having blanks to seperate it?
If anyone of you knows how to split "123-234" into 123 and 234 (meaning the two integers) then please let me know. At the moment I am able to split "123 - 234" into "123" "-" and "234" but well, if there are no blanks inbetween my programm will crash. And I really would like to avoid this 
Thanks.
Stephan.

Why use split? Just use SubString:
Dim a As Integer
Dim b As Integer
Dim s As String = "123 - 456"
Dim i As Integer = s.IndexOf("-")
If i < 0 Then
'must be in xxx form
a = Integer.Parse(s)
Else
'in xxx-yyyy form, so parse
a = Integer.Parse(s.Substring(0, i))
b = Integer.Parse(s.Substring(i + 1, s.Length - i - 1))
End If
This will work if spaces or no spaces. If you need the strings rather than the integers, just use stringa = s.Substring(0, i).Trim. The trim will remove leading or trailing spaces.

Well, seams as if VBA for Excel does not support "Integer.Parse"
Or does it? At the moment I am on Office 2000 but might soon be updating to Office 2003.
I had a look and the help says there is only a normal parse operation. The examples says parsing a telephonenumber and seperating it into two Cells (similar to my example). Maybe I could use this one ...
Or was your example supposed for .NET? Because actually I do not have this installed here and at the moment I do not have access to it. So I have to get along with what Office is offering 'til I will be able to use .NET

Sorry,
In Excel, it would be something like:
value = "123 - 456"
Pos = Instr(value,"-")
If Pos > 0 Then 'I think position starts at 1 in Excel
a = Val(Left(value, pos - 1))
b = Val(Right(value, Len(value) - Pos))
Else
a = val(value)
End If
I can't check at this computer because I don't have anything with old vb on it here.

now that i ponder on it a bit, when i use the split function in c# i simply do the following -
myString.split('-')[0] //gets xxx
myString.split('-')[1] //gets yyy
I wonder if you couldn't do the same for vb.net i.e.
myString.split('-')(0) //gets xxx
myString.split('-')(1) //gets yyy

You can but VB.net likes you to specify that the splitter character is of type char. Also the single quote is the comment character in VB.Net so you have to use double quotes.
myString.split("-"c)(0) 'gets xxx
myString.split("-"c)(1) 'gets yyy
If you have knowledge, let others light their candles at it.

Sorry for writing this Question to this part, but i write it in SQL part, i got no answer
I have a table named "DebitsAndCredits" which has fallowing columns
AccountNumber char(12)
DebitCredit bit
Amount money
I have the same table in two databases which are MB0001 and MB0002
I would like to join them in a one result set.I write
SELECT DISTINCT (AccountNumber ) ,
(SELECT SUM(Amount ) FROM DebitsAndCredits m
WHERE m.DebitCredit =0 AND m.AccountNumber =f.AccountNumber ) as Credit,,
(SELECT SUM(Amount ) FROM DebitsAndCredits m
WHERE m.DebitCredit =1 AND m.AccountNumber =f.AccountNumber ) as Debit
FROM DebitsAndCredits Order BY AccountNumber
UNION
SELECT DISTINCT (AccountNumber ) ,
(SELECT SUM(Amount ) FROM DebitsAndCredits m
WHERE m.DebitCredit =0 AND m.AccountNumber =f.AccountNumber ) as Credit,
(SELECT SUM(Amount ) FROM DebitsAndCredits m
WHERE m.DebitCredit =1 AND m.AccountNumber =f.AccountNumber ) as Debit
FROM DebitsAndCredits Order BY AccountNumber
i dont know why it is not working in my way. I expect a table has three columns (AccountNumber,Credit,Debit ) as a result.
What is Wrong?What do u offer for me?

you must specify the database names in the query eg.
Select ..... from MB0001..DebitsAndCredits m1 ......
Union
Select ..... from MB0002..DebitsAndCredits m2 ......

And thank of all any way
note:
the excel use interop dll to connect to the assembly dll

Well, there's nothing we can tell you since you haven't provided any useful information about the component RTD is connecting to. Is this a component that you wrote or a third party? What does this component do? We would also need to know about any error messages that are thrown.

I have an application written in VB6 that allow others to write plugins in the form of an ActiveX control. Now I want to allow dotnet usercontrols as plugins as well.
There are examples on the net of how to expose a windows forms usercontrol to COM as an ActiveX control. Although not actually supported by the framework, these seem to work if the usercontrol is loaded in a VB6 form. However, when the dotnet usercontrol is loaded inside a VB6 usercontrol, arrow keys stop working. Apparently they are interpreted as tabs (even if focus is in a textbox or listbox).
Now my question is, first, is there a way to solve this? Any pointers would be appreciated.
Second, since this is not really supported and I already have seen problems, I'm getting worried about more problems ahead. Is there anyone who has used dotnet usercontrols in VB6? Does it work well, or are there other problems that will appear later?

Take a look in the System.Drawing namespace which contains classes for drawing anything you like on a form or usercontrol.
If you have knowledge, let others light their candles at it.

Good day to all,
I have a Access2000 database and would like to edit my entries from the internet. How could I go about setting the webpage and site up? How can I also provide security as I want to limit the access to my database to a number of users only. Thanks alot.

Well, first of all you need to write an ASP.NET site. I'd recommend using C#, because it sounds like you need a lot of help, and there are a lot more people answering C# questions, and C# samples, here on this site.

You can filter via IP, or set up a password system, whichever suits you better.

Hi Christian,
Thanks for the opinion, but my project is using Visual Basic and database is Access. My project dateline will be in a few wks time. Hence I dont think there will be time for me to merge from one programming platform to another.
I will stick to VB and Access. Any help from the rest?
Rgds,
James

Do you mean VB6, or VB.NET ? If VB6, you're screwed. If VB.NET, you can still use ASP.NET, but you'll find less help online, at least here.
Why do you have a project on for which you have 2 weeks, and not the faintest idea how to do it ?

First, since you mentioned "browser", your question really belongs in the ASP.NET Forum, not VB.NET.
Second, fix what? Be sure to include a code snippet in your post so we can see what's going on and how your doing things.

I have a copy application that copies a folder from one location to another.

Try
LogEvent("Copying " & loc1orginal & " to " & loc1backup & " ")
fso.CopyFolder(loc1orginal, loc1backup)
If chkLocation2.Checked = True Then
LogEvent("Copying " & loc2original & " to " & loc2backup & " ")
fso.CopyFolder(loc2original, loc2backup)
End If
Catch ex As Exception
LogEvent("Exception generatted: " & ex.Message)
berror = True
End Try
I would like to add a progress bar to the app for the user, simple! But how do I measure the values needed to feed the nim and max values to the progress bar comtrol? Will I need to compare size of the directories and match from there????
Please help

If your going to use the File System Object CopyFolder method, you really can't add a meaningfull progress bar since CopyFolder will not fire any events you can subscribe to to update your progress bar. A couple of alternatives would be to fire off the Copy process you find in Explorer, which has its own progress bar, or write your own Copy function that can track the number of files/bytes it needs to copy and update a progress bar itself. Using the code you have now, you can't add a progress bar to it.
