as you don't provide much infos, we cannot help you.
if you feel the problem is more relating to the VB part of your code, ask in the VB forum.

What happens if you use the DLL in a separate application created with VC++?

Are you calling the event from a thread? If so you cannot do it directly. You need marshalling before you could fire the event from your worker theard. Tell me are you calling it from a worker thread?

There's a lot that could be wrong, especially since it's a multithreaded server.
One common mistake is to fire events from a secondary thread without setting up the apartment for the secondary thread properly and not marshalling interfaces when crossing apartment boundaries.
If you by any chance are firing events from a secondary thread, have a look at Michael Lindig's solution for the problem here[^].
Another way is to post a message to the thread that created the server and fire the event from there.
Don't forget to call ::CoInitializeEx() / ::CoUninitialize() in you secondary thread if you're using any COM objects inside it.
Hope this helps

It's supposed to be hard, otherwise anybody could do it!

After executuin the application the windows will be started same position.
How we fix the position?

You don't need to change your project name in order to change the executable name. To change the output file name, it depends of the IDE you are using. For VC2005, go into your project properties -> 'Linker' -> 'General' -> 'Output file'.

We have a downloadable COM component which traps user actions on html form elements,stores them and later replays them.
Now,assume the distributable is UNICODE built.
And heres an sample scenario to capture the value from a text-box element on a form:
CComPtr<ihtmlelement> spElem;
CComVariant varval;
hr=spElem->getAttribute(CComBSTR(L"Value"),FALSE,&varval);
if(FAILED(hr))
{
return S_FALSE;
}
we convert it into a wstring using OLE2T (unicode)- and later set it back on the element as a BSTR, during replay.
Will this arrangment handle clients from ASCII locales too?or does a ASCII entry need a MBCS distributable?i.e can wstring handle both ASCII and non-ASCII locales seamlessly?

Hi, all...
I do the followings (in VC++ 6) :
1. Create an 'MFC AppWizard (exe)' project
2. Just delete the text : "TODO : ..." in the dialog box
3. Add an EditBox (IDC_EDIT1)
4. With ClassWizard, define this MemberVariable for IDC_EDIT1 : Member : m_edit1, Type : CEdit
5. For supporting Unicode parameters :
5.1. Add the _UNICODE in -> [Menu]->[Project]->[Settings...]->[C/C++] (with category General) -> in {Preprocessor definitions}.
5.2. Add wWinMainCRTStartup in ->[Menu]->[Project]->[Settings...]->[Link] (with category Output) ->in {Entry-point symbol:}
6. Add EN_CHANGE Message to IDC_EDIT1
6.1.Write this line in EN_CHANGE Message handler function for IDC_EDIT1 (void CTestDlg::OnChangeEdit1() ) :
m_edit1.SetWindowText( _T("Any text, even NULL") );
OK, then the program builds successfully, and runs...
Problem : now, I input a character in editbox, Oops! the program terminates! 
Whats the problem ?!
Thanks.

the program terminates, or hangs ?
calling SetWindowText() generates an EN_CHANGE event to be thrown.
change your event with this :
CTestDlg::OnChangeEdit1() {
static bool b = false;
if (!b) {
b = true;
m_edit->SetWindowText("Hello");
b = false;
}
}
|
|
|
|
|
Thanks... 
I think it's just abuot calling again and agian the EN_CHANGE message...
It's interesting that the program terminats not hangs ! 
|
|
|
|
|
hum, i think it terminates when crashing because of a full call stack...
anyway, be careful when handling even which you can potentially rethrow.

I'm curious why you'd want to set the text of an edit control in this fashion. If you are going to hard-code text in the control no matter what is typed/copied into it, there are better alternatives.

For starters:
Set the value in the dialog's template.
Call SetWindowText() in the dialog's OnInitDialog() method.

but this will set the value for the beginning only. if the user modifies the editBox after then, nothing will be done...

That's exactly what his code is doing anyway. No matter what is typed/copied into the edit control, he is hard-coding the control with a call to SetWindowText(). Not only is this a bad design, it results in multiple EN_CHANGE messages.

I use an CString member variable for a listbox to get the selected item data, so if I use a CString member variable for editbox too, I should use the UpdateData(FALSE) to update the changing, then the selected item in the listbox will change and the first one of those items will bw selested.
It's my reason!

Which you shouldn't be. Use a CEdit member variable instead.
Mohammad Rastkar wrote: ...I should use the UpdateData(FALSE) to update the changing
There is no valid reason for using UpdateData(). Yes, the framework calls it (i.e., when the dialog is initialized and when OnOK() is called), but calling it explicitly is not necessary.
I'm not sure what this talk of listboxes has to do with my initial comment about edit controls and your EN_CHANGE handler.
