What does this error mean in VB6? Function or interface marked as restricted, or the function uses an Automation type not supported in Visual Basic.
I keep getting it when i call a particular method of a dll that comes with windows xp and beyond (in system32 called upnp.dll)

Basically, im just searchign for uPnP devices using the uPNPDeviceFinder classes .FindByType method, .FindByUDN works, but FindByType gives an error:VB6 gives a compile error when I attempt to call the method:
Function or interface marked as restricted, or the function uses an Automation type not supported in Visual Basic.
why i am getting it. I am referencing and using the upnp.dll file as found in yoru system32 directory - when i reference and use this in VS2010 (say, vb.net) it all works and no issues are found, but in VB6, i get the error above.
Is there a simple sleep function in Visual Basic that doens't involve thread.
Something similiar like there exists in: C: sleep(1);
We also tried this code:Declare Sub Sleep Lib "kernel32" (ByVal milliseconds As Long)' pause for 5 seconds

I am trying to transfer a very complicated Matlab function into visual basic. It takes a matrix input and gives 4 outputs.
From my own research I found something called Matlab CODER, which can transfer matlab code into C/C++ code, however, this function is too complex for that. So I guess now my question is, it is possible to call my matlab function somehow within VB and store the outputs for use within my VB program?
The matlab function looks something like this:
function [f,x,s,c,l] = mytest(Y,varargin)
%Code here...
end % function
I'm working on a small freeware application in Visual Studio 2008 Standard that will match geographic data to a geographic position. For this I need some mathemathical functions and one of them is how to detect if a point is inside a polygon. There's a great solution for this from the Microsoft team at: [URL]
but it is in a different programming language that I do not know anything about. How can I use these functions in my program? I'm afraid that if I try to rewrite them in Visual Basic I'll make mistakes that I can't detect. To be complete, I'm not using screen graphics so I really need a mathemathical solution.
I'm doing a baseball program for a class project. And I almost have it complete, but it's giving me a syntax error. I can't figure out what i'm doing wrong. I'm using two functions to return a value for different type of baseball tickets to the button that calculates them. Here are the instructions 1.)User selects whether to purchase season tickets or single-game tickets 2.) User enters the number of tickets needed and the type of seats based on whether they selected season single-game tickets.3.) User clicks the Compute Ticket Cost Button to display final cost4.) User clicks the Clear Form button to clear the responseI just can't figure out what I did wrong. I know it's something stupid that i'm doing.the errors are happening inside the btnCompute sub routine. with syntax erros on SingleGameCost() and SeasonalCost() line 114 and 118

I am working to make a function that will update the back color of a text box based on multiple variables values. I can write the code to do the calculation, but I am not sure how to make the function realize which text box to update (as I will have about 30 different boxes). Below is the code that I have for each box so far, but I will have quite a few more, and would rather use a function to reduce the amount of code, and also make it cleaner as well.
If sngPreviousPrimaryPropertyTotal >= sngPrimaryPropertyTotalCost Then
txtPreviousPrimaryPropertyTotal.BackColor = ColorProgramLightGreen
Else
txtPreviousPrimaryPropertyTotal.BackColor = ColorProgramLightRed
End If
[Code] .....
Or is there a way that I can tell the function that it's updating the text box that call the function in the first place? Say if txtBox1 has updated text and calls the function, then the function 'knows' to update txtBox1, but will update txtBox2 when it's called by txtBox2.
In my VB.net code i have:
cmd.CommandText = "SELECT * FROM [strfg].[dbo].[Myfunc] (@MyParam)"
Dim myparam As New SqlParameter("@MyParam", a)
cmd.Parameters.Add(myparam)
The function (runnig on SQL server) returns a table with four columns, one row.How do I call this function from Visual Basic? cmd.ExecuteScalar() is obviously not correct. In c++ I use a recordset. What is the equivalent in vb? Does anyone have a short example?
Just so it's known, this question is mostly academic, even though I tried to use the concept in a real-world solution. I realize the example is contrived, but I believe the concept is valid.I want to write some fluent code like this:
[code]...
I realize that I can't force an anonymous type into a specific type (like implementing an interface or some other class), and I don't want the overhead of defining a specific class just to match my desired fluent name with the actual method name. So I was able to make the code work like this:
copy(my_first_file).to.Invoke(my_second_file)So there is no IntelliSense or type awareness there, and I have to include the Invoke in order to have the method run. How can I get more type safety and exclude the Invoke method, under these constraints: Anonymous Type returned from Method No additional classes or interfaces Preferably, I do not want to pass in another parameter to the copy() method that tells what type to return, unless copy becomes a generic method (but I think that means defining another class/interface, which I don't want to do)
I've found this nice library to make localization in a .NET application. Problem is, this FairlyLocal is build in C#. Now I downloaded a converter to make it happen in VB.NET. But it seems my project is using the FairlyLocal.dll which is a binary and uses _() where '_' is the name of the function. All I want is to change the '_' to 't' so it would work with the VB.NET application too. How is this possible. I'm a greeny to VB.NET and .NET overall so please don't be rude.
Problem I get is at the '_': Identifier expected. [Code]
I also tried what Justin said (with the brackets []) but that doesn't work either.
I've a vb.net class library and my c# application is accessing that method. My C# code gives me compile time error that 'Start' is not supported by language, where Start is my method name.

I want to make an numerical integration method with takes in an analytic function and integrate it over a specific interval. For the numerical integration procedure I want to use some procedures in nr.com. The problem is that these are programmed in C++ and they uses functors to pass a function to the integration method. How can I do this in VB 2010?
I want to initialize the function (i.e. set a=1,b=0 for function y(x)=a*x+b) and then pass the function to the integration method. Then when the integration method call the function it only calls the function with one parameter (i.e. x since a,b is already set)
What is the best way to do this in VB2010?I want to make a general integration method where I can pass any single valued function and integration limits.
I have just started using VB, and from what I have found so far it seems like the tools you have is
- to us a delegate for the function
- to use a lambda expression for the function
- send a pointer/adressOf
- to create a function class/structure and submit this to the function
As for now I am most inclined to create a function-class. But I am not really sure how.F.ex. I make different classes for each "uniqe function" I want to integrate, but how can I pass them to the integration function when I need to specify the argument type in the integration-function-call?This seems like a basic problem which applies to many Math operations, so I think it would be very useful to clarify this.

Maybe this question should be in an ASP forum, but it is a VB question. This simple web service allows you to type in your name and it response with an alert box with you name.
My question is, How can you call a function with 2 arguments when the function is only defined for one. I understand that the second argument is actually a method that handling the respons, but how can you interchange function arguments for methods and how do you know that there are methods for

Write code or use tableadaptors, bindingsources, dataset, etc.? I have experience with the older ways i.e. connection strings, ado code, sql, etc. but was hoping the newer tools in vs would make the user interface easier and more flexible. So far i have been disappointed. Am I wrong and I am missing something? Am I alone in this opinion or ? What is your past experience in VB and have you found vb.net to be a step forward in db user interface design? if your answer is yes then what is the easiest way to put a table record count into a text box? should i bypass all the new stuff/objects ( adaptors, binding sources, navigators, designers, etc) and just write code or what?

i am beginner about general programming. Please give me basic shared functions .
I only know few functions such as : Public Shared Function lon(ByVal a As Integer, ByVal c As Integer) As String Public Shared Sub trung()
in the old days i could so something like
GWBasic
10 A$="ReallyLongStringInSmallSpace": B$="tiny"
20 PRINT USING" ASDFASDFASDF ASDFASDF"; A$; B$
Output:
"Re ASDFASDFASDF tiny ASDFASDF"
it would automatically truncate large strings to fit in a small assigned space, and it would use empty spaces for strings too short. it made it VERY easy to print fixed front text tables in aligned columns by automatically truncating long lines and expanding using spaces (chr 32) where needed.i've already looked at .Format but it seems just for dates, times, currencies, and various byte/hex formats.
this wont be easy to explain clearly but here goes..i have something that works fine in VB but not in C#.i have 2 classes, each class implements a different interface. each interface exposes an Initialize() function that should get called automatically when the plugin loads. since each class has an Initialize() function, i can watch both functions get called in the log. this works fine in VB.
when i do this same thing in C#, only the Initialize() in the first class gets called. anyone have a clue as to why this might be happening?
[Code]...
as you can see the code is identical in both languages. why does it work in VB and not in C#?
