wnd is not a handle to the window it is an object of CScrollView  your question was wrongly framed.

Thank you God.

I wrote follow ...
CScrollView * pScroll = (CScrollView*)CScrollView::FromHandle(hWnd);
if (pScroll->IsKindOf(RUNTIME_CLASS(CScrollView)))
Thank you again. 
Best regards,

This method should work, but only in the UI thread of your app:
CWnd *pWnd = CWnd::FromHandle(hwnd);
if (pWnd->IsKindOf(RUNTIME_CLASS(CScrollView)))
{
}

Please help me I lost my night sleep. Tell in simple code.
From my VB client I am passing simple string "Siddharth", to a win32 dll function GetUserName(DATATYPE)(if DAtatype is BSTR or wstring tell me how to convert it into string in dll function declaration). My program should run in 98 as well as NT. I am trying lot of examples but they all are for long. When I convert it to string nothing works out.
VB client
Dim x as string
x = "String"
GetStringFromVb(wstring *)
end
Win32
GetStringFromVb(wstring*)
{
vector MyString;
MyString.push_back(wstring);
{
//..Lot of string manipulation
}
}
One more issue. in the win32 DLL.h if I declare stl parameter, it is not accepted by the compiler.

Widebytetomultibyte will help you convert wstring to string.
But since the input is from VB i guess it must be BSTR
so to convert BSTR to string
put USES_CONVERSION as the first line in the function
and when you want to convert BSTR to string
use this macro OLE2A to finish the job.
Still Alive!!!
Thank you God.

Bulls eye boss, in identifying the problem. Really U are great. I am trying it. Will get back to you.
One point I want to clarify USES_CONVERSION is not included in Index part of MSDN. Nor OLE2A

include atlconv.h for uses_conversion stuff
also you can refer this link for futher understanding
USES_CONVERSION[^]
its not a complete doc but its good to understand and about the link in MSDN
try searching it, i guess its in of the knowledge base article.

Thank you God.

During write IIS Filter, I want to find and send message to other windows, but I find the ::FindWindow and ::PostMessage seems does work inside IIS Filter codes. I think maybe they work in different desktop. Would you please tell me how can I make them communicate? Thanks a lot!
|
|

|

Have you tried checking the option to allow the WWW service to interact with the desktop? This would be in the controlpanel/services applet.
onwards and upwards...

I have an unmanaged MFC project that I am referencing from a managed MFC project. The unmanaged project builds successfully, but the build of the managed project fails during the link because it cannot find the external symbols from the unmanaged class. In what directory should the dll file be placed for the unmanaged project? The intellisense operates correctly referencing the unmanaged class within the source for the managed class. However, the linker is not finding the external symbols for the compiled class. Any suggestions?

Hi !
(calling an ActiveX thing from Delphi 7)
Any clues as to why I am getting the following error msg ?
error msg; Undeclared identifier: 'Layer2'
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<Script
procedure TMinMap.MGMap3onMapLoaded(ASender: TObject;
const Map: IDispatch);
var
Layer2: String;
begin
Layer2 := 'Streets-All-With Names';
TMinMap.Layer2.setVisibility(true);
end;
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
Thanks, Cliff

woah! what language is that? Greek?
Still Alive!!!
Thank you God.

Greek would possibly be easier !
It's a messy post, but between the<<<<<<<<<<<<'s
is a piece of Delhpi 7 script that is trying my patience. There isn't a Delphi forum here so. . .

Thanks Mike,
Didn't fix it though.

No knowing delphi I have a problem with these two lines. In one you use Layer2 without a TMinMap. Are they two different variables named Layer2? One as an object variable and one as a local procedure variable?

John,
procedure TMinMap.MGMap3onMapLoaded(ASender: TObject; const Map: IDispatch);
var
// the following line declares the variable as
//a String
Layer2: String;
begin
// the following line assigns a value to the
//String
Layer2 := 'Streets-All-With Names';
// and this one is supposed to instruct the
// program to set the layer named
//'Streets-All-With Names' visible
TMinMap.Layer2.setVisibility(true);
end;
|
|
|
|
|
Did you try?
procedure TMinMap.MGMap3onMapLoaded(ASender: TObject; const Map: IDispatch)
var
Layer2: String;
begin
Layer2 := 'Streets-All-With Names';
Layer2.setVisibility(true);
end;
John

John,
It returns a different error
"Record, object or class type required"
I will change the name of the variable Layer2 and see if that works.
Thanks, Cliff
