IIRC, calling overloaded COM methods from VB6 is not supported.

Is it the same case with calling COM method from VBA?

Any documentation that i could find for this?
I did not get anything from search engine...

AFAIK, it's the same problem. I can't find any documentation on it. I just remember having one hell of a time trying to get it to work, then I stumbled on something saying it doesn't - about 8 years ago.

VB.NET / Printing Webbrowser Control

8-Jul-09 7:11

If the other app exposes some kind of interface, you'd have to use that interface to interact with it. How you do that is entirely up to what is exposed by the other app.

As for handling the click of a button in another app, I'm afraid you out of luck. Your app will never get any kind notification that anything was clicked on. Unless, of course, the other app exposes such functionality through some kind of interface that it exposes. There is nothing "generic" that is supplied by Windows to do this.

Hello,

I need some help related to printing from .NET's Webbrowser control. I already figured how to print and how to change header/footer, margins and so on ( Some Cool Tips for .NET[^] ). But how I can change the printer that is used for this printjob?

I know I could use webbrowser's .ShowPrintDialog() or .ShowPageSetupDialog() methods, but my users shouldn't gambling with this dialogs... they only want printing, without any dialogs, so I must select the printer in my source code.

I also know I could change the default printer for exactly the time my printjob is in the pipeline - but that's not fine art, isn't it? That seems to be the ultimate brutal solution, so I would prefer a more elegant solution for my problem. Any suggestions?

Thanks for all answers, and I hope I made my problem understandable...

That can be done using PrinterSettings.PrinterName property.

Can any one please tell me how to make a VBscript messagebox support unicode characters.
MsgBox("ストケースの部分をテ",vbYesNoCancel + vbQuestion, title)

The string in Msgbox is displayed as squares in the messagebox

Thanks in advance.

Strings are already Unicode in VBScript. The MessageBox is not part of VBScript, but is supplied by the system. There is no way to modify how the MessageBox works. It would appear that the system does not have the appropriate language pack installed to show your text properly.

Hi. Im new to visual basic 2008. I am now learning classes and how to make an instance of a class. Below are my codes. I have a problem in which the system says my "Calculator.DateCalc2008()" is not defined.

The following is my class code.

PublicClass DateCalc2008

Private _startDate As DateTime
Private _endDate As DateTime
Private _span AsInteger

PublicProperty StartDate() As DateTime
Get
StartDate = _startDate
EndGet
Set(ByVal value As DateTime)
_startDate = value
EndSet
EndProperty

PublicProperty EndDate() As DateTime
Get
EndDate = _endDate
EndGet
Set(ByVal value As DateTime)
_endDate = value
EndSet
EndProperty

PublicProperty Span() AsInteger
Get
Span = _span
EndGet
Set(ByVal value AsInteger)
_span = value
EndSet
EndProperty

PublicSub IncreaseDate()
EndDate = StartDate.AddDays(Span)
EndSub
EndClass

This is my object codes. Reference from above.

PublicClass Calculator

PrivateSub StartDatePicker_ValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles StartDatePicker.ValueChanged

Dim myCalc AsNew Calculator.DateCalc2008() //THE PROBLEM!

myCalc.StartDate = StartDatePicker.Value
myCalc.Span = 7
myCalc.IncreaseDate()
EndDate.Text = myCalc.EndDate.ToString()
EndSub
EndClass

I suspect VB is not happy because it is confusing the class Calculator with the namespace you are using. If both the calculator class and the DateCalc2008 class are in the same namespace you should be able to omit Calculator when declaring your variable, i.e.

Dim myCalc AsNew DateCalc2008()

Dim myCalc As New Calculator.DateCalc2008() //THE PROBLEM!

take off the work Calculator

Dim myCalc As New DateCalc2008()

DateCalc2008 would need to be nested within Calculator to be declared like that.

I tried, but still has the error. ok. cause i following the directions of a book, it taught me this way. "To run your new DLL file, you need to add a project with a user interface to the same solution that holds your DLL project."

so, the Class DateCalc2008 is the .dll file which is used as a reference for the user interface which is the class Calculator.

Thanks Alot! =)

Does your new project have a reference to your dll ? If not, that would cause this error.

yup. it does. Assuming i am following the book correctly, which im pretty sure i am.

what does each part of this code means anyway? "Dim myCalc As New DateCalc2008()".

just a thought, so usually if i were to have a class and want to create instances of it, i could just write it all out on the long sheet of codes instead of using the .dll as reference method?

Thanks a million!
