After much searching, I haven't seen any controls that do everything you describe. Not even half of what you want, actually...
If I were in your shoes, I would write the thing myself...

I set the form1.moveable = false when designing. But I want that the form1 could move in running. Therefore I set the form1.moveable=true in a button click events. However it cannot be done. It shows that the .moveable is readonly and cannot be changed while running. How can I make a form moveable in running while be set to unmoveable in designing?
Thanks!

I have to question why this would be an issue? From what I can tell, the Moveable property has no effect at design time, only at runtime. The form in the designer is locked to the upper left corner of its document window, regardless of this property. Also, you can change the position of the form using the Top and Left properties, even when Moveable is false. I don't see how that window is moveable during design-time...

Please tell me how to use CallByName function in VB.NET.
Thanks,
|
|
|

CallByName lets you call a Function or manipulate a Property on an object, such as a TextBox or other class:
CallByName(TextBox1, "Text", CallType.Set, "New Text")
CallByName(TextBox1, "Hide", CallType.Method)
Dim col As New Collection()
' Store the string "Item One" in a collection by
' calling the Add method.
CallByName(col, "Add", CallType.Method, "Item One")
' Retrieve the first entry from the collection using the
' Item property and display it using MsgBox().
MsgBox(CallByName(col, "Item", CallType.Get, 1))
The down side to using the CallByName function is that it is very slow. There is also no type checking of arguments, so handling errors properly becomes a bit of a pain.

(1) How can I code a text box to accept characters of the alphabet, a spacebar (and a - for double barrel names) only? Ideally this text box is named txtName and is supposed to accept people’s names.
(2) In VB. NET how can I create a library of common procedures that I will constantly need to copy and paste to different projects
Been always great to be part of this forum, especially when I know they know more than what I know…..

You could run a regular expression on the contents of the textbox changing, and disable the OK button (or whatever) until the expression matches.

Try creating a Class Library project. This allows you to create a .NET assembly (held in a DLL) that can contain your common code base.

I have written a programme that should allow a pupil to enter his details and then the programme will display the pupil’s profile using a dialog box. I have worked the rest fine but I have difficulty in setting the leap year limits for the month of February. I have tried juggling around my code in many different ways, but seem not to get it right. I have left the code with an array of 10 leap years that I consider to fall within a pupil’s age. I definitely know that the problem is not with coding an array, it’s something else. I have said:
For Leap year 1 To Leap year 10
If the month is "February" And CInt(The “Value” of numeric-up-down representing the pupil’s year of birth) <> Leap year And [Day is ("29") Or ("30") Or ("31")] Then
ErrorMessage1
Exit Sub
End If
If the month is "February" And CInt(The “Value” of numeric-up-down representing the pupil’s year of birth) = Leap year And [Day is ("30") Or ("31")] Then
ErrorMessage2
Exit Sub
End If
However, an error exist somehow in the code, may you give me an idea of where the problem is.

You might want to learn what the rules for leap years are:
If the year is divisible by 4 then it's a leap year. However, if the year is also divisible by 100, then it is not, but it it's divisible by 400 then it is.
Hence 2000, 2004, 2400 are leap years, but 1900 and 2100 are not.
A leap year has one additional day, which is February 29th.
------------------
If you're using .NET, just use DateTime.Parse or something to see if the date entered is valid or not (as the DateTime APIs handle this stuff anyway, so you're better off using them). VB6 may have a similar API.

I'm making a small program wich has to be used to input bills. Becuase of this, it will have to format numbers for me.
Now, for example
When I my input is 3.50 then my output has to be 3,50 AND NOT 3500!!!!!
So my question is, how do you format numbers so that the "." becomes a "," ???
<<<eRiK>>>
|
|
|
|
|
vb6 ?
Dim n
n = 3500
MsgBox FormatNumber(n, 0, , , vbTrue)
|
|
|
|
|
I think you dont get my question well... When you enter a value (for example totall bill) most people don't use a "," but a "." . But if you enter a "." in VB, he will read it as a thousand sign, so 3.50 -> 3500 . But, I want him to make a value of it so 3.50 -> € 3,50 . Eventually without the €-sign !!
I hope you could now help me better ( by the way, it has to work with textboxes and not with msgboxes!!! )

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

Dim tempNum As String = Format(num, "n")
tempNum = tempNum.Replace(".", ",")
Return tempNum
End Function
(...)
Dim myNum As Double = 54.25

I am trying to make an application that stores and manipulates data. The problem is that I will be trying to market this application to small vendors (Strip mall stores) who cannot afford expensive SQL Server licenses.
My example is a small store (e.g. laundromat) order tracking system. Is it possible to write an application like that without using a database backend?

Why don't you use MS Access? It comes free with Office

I was thinking more in the line of using files to store data but that pro'lly isnt a good solution coz of the whole locking issue with multi-users. Might as well write my own sql server. Access is a good solution but there are problems when the database size increases.
I was thinking more from a business model side of the product. Is it cost effective to defer the cost of SQL Server to the user. Maybe get a 1 seat license since only the application will be using the database? I just wanted to figure out how to price the product before i actually start working on it.

I was just wondering how you use the printer that is selected by the user through the common dialog box. Everytime i tell it to print it just prints to the default printer. How do i make it print to the printer selected. It would be great to get the code for both VB 6.0 And .NET . Thank you for any help.
