If you created the dll on .NET platform, you will still need to have .net framework installed on the target machine. Here is a sample class that's exposed to COM. You will also need to register the dll with regasm.exe utility found in %windir%\microsoft.net\framework\v1.1.*.
You can use this library in vbscript or vb6 (or any other COM client) simply with:
Set demo = CreateObject("Demo.demo") 'notice the ProgId below
Here is a link with some more explanation: http://www.codeproject.com/dotnet/nettocom.asp?df=100&forumid=14076&exp=0&select=1028513[^]
Imports System.Runtime.InteropServices
Imports System.Text
<guid("e3928d8b-4eca-42c1-81cf-482f1c18b5f7"), interfacetype(cominterfacetype.interfaceisidispatch)=""> _
Public Interface _demo
<dispid(1)> Function GetString(ByVal strString As String) As String
End Interface
<guid("e601fd54-fa5b-4b62-a7ae-abbe701b8626"), _
classinterface(classinterfacetype.none),="" _
progid("demo.demo")=""> Public Class demo
Implements _demo
Public Function GetString(ByVal strString as String) As String Implements _demo.GetString
Return "COM Sample"
End Function
End Class

Some parts of the class got stripped off when i submitted it (because of the < tag), so it won't work. But look at the link above, it has more in depth information.

Hi
When you want to write your class in C#, try adding a ComClass rather than a simple class. (the ComClass should be availabe in Project>AddNewItem if I remember correctly.
Then make your dll file, C# would register the class for you and then you can simply use your class on your machine using CreateObject.
(to use the class on an other machine, you must first use regasm.exe as told to you.)
Hope it was helpful.

formula=Sum ({@DebitBalance})
Why above function cause error "This field cannot be summarized"
Actually @DebitBalance has value of number. Any ways that i can sum up @debitbalance?
|
|
|
|
|
Is {@DebitBalance} a formula too?

yes, inside that is :
if Sum ({Entries.Debit}, {Entries.AccountName})>Sum ({Entries.Credit}, {Entries.AccountName}) then
formula= Sum ({Entries.Debit}, {Entries.AccountName})-Sum ({Entries.Credit}, {Entries.AccountName})
end if
|
|
|
|
|
Although the formula always returns number, I don't think you can sum it. The Crystal Report couldn't recognize it as number. You have to look for another solution.

Better yet, Amazon and get yourself a couple of good books on VB or VB.NET, whichever your using.

If your code is well written, you should be able to just write an ASP.NET presentation layer, but as has been said, it's a totally different model, and the way you code it is way too different for a wizard to deal with.

I have a windows apllication which has flexgrid.This application works fine when it is run from the local hard disk.But when this application is accessed from another computerin the network it gives.System.security.securityexception
Using try catch i found the error was Request failed
What i actually want is deploy my application on one machine and acces it from other machines without deploying on each and every machine

Why does the flexgrid give a security exception ? Is the error message wrong, and you just need to deploy the grid ? ( Flexgrid isn't a WinForms control, it's an old one, isn't it ? )

You really can't do that with the presentation part of the code, although you can do it with your data stuff, if you can configure all instances of the app to look to your machine. This means you need to code for concurrency issues, obviously.

Hi all,
I have given an option of deleting a row of a grid by pressing Ctrl-F6
But this key is not working
The same function is getting called by other keys like Ctrl-F7
Since Ctrl-F6 is a windows shortcut key to toggle through windows,so how to disable this key of windows.
Please get me a solution
Thanks in advance

I am trying to use the ms internet transfer control to download binary files from the internet using the execute statement. I am only using a very basic piece of code as a test, however by using the debugging tools, and stepping through the code one line at a time, the Inet controls statechanged event is not called. The execute statement is
Inet1.Execute URLname, "GET"
I have tried setting the other properties of the inet control to no avail. In addition I thought about adding a piece of code either before or after the code to make sure the inet control is not currently executing, something like
If Inet1.StillExecuting = True then
DoEvents
End If
If anyone has any thoughts on what is going on I would be very appreciative,
Cheers,
Mark
