Hi,
when I try to compile the following code
template<class type,="" class="" arg_type="">
class CBanana : public CObject
{
protected:
struct CApple
{
int x;
int y;
};
int GetInt(int);
CApple* GetApple(CApple*);
};
template<class type,="" class="" arg_type="">
int CBanana<type, arg_type="">::GetInt(int i)
{
return i;
}
template<class type,="" class="" arg_type="">
CBanana<type, arg_type="">::CApple*
CBanana<type, arg_type="">::GetApple(CBanana::CApple* pApple)
{
return pApple;
}
which is based on code found in the MFC afxtempl header, I get a compile
error on the line CBanana<type, arg_type="">::CApple*
syntax error : missing ';' before '*'
if I replace the above return type with an int it then complains
instead about the parameter CBanana::CApple* pApple
'pApple' : undeclared identifier
it doesn't like my CApple !
Any ideas why ?
Nvat.

Hi All,
Im writing a dll in ATL COM called by a vb.net client. the client passes a 2d integer array when it calls MyMethod.
i have tow problems
I. i have trouble accessing the values in the array passed, i get junk values. this is the code.
<br />
STDMETHODIMP ExposedATLClass::MyMethod(SAFEARRAY **psa)<br />
{<br />
AFX_MANAGE_STATE(AfxGetStaticModuleState())<br />
long arrlengthx,arrlengthy;<br />
long **myarray;<br />
int indexx,indexy;<br />
try<br />
{<br />
arrlengthx=(*psa)->rgsabound[0].cElements;<br />
arrlengthy=(*psa)->rgsabound[1].cElements;<br />
myarray=(long**)malloc(arrlengthx*sizeof(long**)); <br />
for(long tempvar=0;tempvar<=arrlengthx;tempvar++)<br />
{<br />
myarray[tempvar]=(long*)malloc(arrlengthy*sizeof(long*));<br />
}<br />
SafeArrayAccessData(*psa,(void**)myarray);
char details[100];<br />
for(int tempx=0; tempx<=arrlengthx; tempx++, indexx++, indexy=0)<br />
{<br />
for(double tempy=0; tempy<=arrlengthy; tempy++, indexy++)<br />
{<br />
sprintf(details,"%d %d %d",indexx,indexy,myarray[indexx][indexy]);<br />
this->Error_Logger(details);
}<br />
}<br />
}<br />
catch(CException ex)<br />
{<br />
char error[300];<br />
ex.GetErrorMessage(error,300);<br />
this->Error_Logger(error);<br />
ex.Delete();<br />
}<br />
return S_OK;<br />
}<br />
in the program
SafeArrayAccessData(*psa,(void**)myarray); returns success
other methods i've used to access data are (replace the line "SafeArrayAccessData(*psa,(void**)myarray);" with code below )
1. using SafeArrayGetElement
<br />
long ai[2]={0,0}<br />
for(int temx=0;temx<=arrlengthx;temx++,ai[0]++)<br />
{<br />
for(int temy=0;temy<=arrlengthy;temy++,ai[1]++)<br />
{<br />
SafeArrayGetElement(*psa,ai,&myarray[temx][temy]);<br />
}<br />
}<br />
here SafeArrayGetElement(*psa,ai,&myarray[temx][temy]); returns index out of bounds
2. using safearraylock/unlock
<br />
<br />
both lock and unlock returned success
all methods return this junk value for myarray[indexx][indexy] -842150451
the values of indexx and indexy are correct and so are the boundaries.
II. my other problem.. no exception is logged.
where am i wrong. pls help
Thanks in advance

I have add teh active-x control in my project:
Open the Project in which intend to use an ActiveX control.
Project | Add To Project | Components and Controls. Taken to the Gallery where choose from Registered ActiveX Controls. Click the Control from the list and click Insert. choose the Control from a list and to confirm the names of the wrapper files which will be created.
From there i got a active=x in dialog box and the wrapper class also.
Now i need to know I have to login to server to take data from that and store in my system.
1: should i need to include ATL controls in my project?
2. how to make use of wrapper class and active-x controls?so thst i can login to server
3. Function in my .cpp file are as follow(API function).
CString CArielAPI::GetServerAddress(LPCTSTR SessionId)
{
CString result;
static BYTE parms[] =VTS_BSTR;
InvokeHelper(0x15, DISPATCH_METHOD, VT_BSTR, (void*)&result, parms, SessionId);
return result;
}
String CArielAPI::Login(LPCTSTR UserName, LPCTSTR Password, LPCTSTR UserId)
{
//username = wwtest2;
//Password = RD9234;
//Userid = wwtest2;
CString result;
static BYTE parms[] =VTS_BSTR VTS_BSTR VTS_BSTR;
InvokeHelper(0x2, DISPATCH_METHOD, VT_BSTR, (void*)&result, parms,UserName, Password, UserId);
return result;
}
4: IfATL is needed then how to work with that any help.....?????

1. No, you're using MFC wrappers.
2. You need to make sure that you create an instance of an 'CArielAPI' object.
Once you've done that, you should be able to call the various methods as you need to. Is there a 'Create' function (or similar name) generated in that class?
3. Refer to the documentation for the control 
4. See #1

i have this function.But i am in great confusion whre should i create object ex:arielapi wartzodlcom.dbaccess.
CString CArielAPI::CreateOrder(LPCTSTR SessionId, long MarketNo, LPCTSTR Amount, short BuySell, short StopLimit, LPCTSTR RequestedPrice, short TradeType, LPCTSTR Exchange, short GoodTil, LPCTSTR GoodTilTime, LPCTSTR Instructions, LPCTSTR Account, LPCTSTR ClientRef)
{
CString result;
static BYTE parms[] =
VTS_BSTR VTS_I4 VTS_BSTR VTS_I2 VTS_I2 VTS_BSTR VTS_I2 VTS_BSTR VTS_I2 VTS_BSTR VTS_BSTR VTS_BSTR VTS_BSTR;
InvokeHelper(0x7, DISPATCH_METHOD, VT_BSTR, (void*)&result, parms,
SessionId, MarketNo, Amount, BuySell, StopLimit, RequestedPrice, TradeType, Exchange, GoodTil, GoodTilTime, Instructions, Account, ClientRef);
return result;
}

|

Ah, no. That won't create an object, that calls a method on the object.
I'd do some background reading on using ActiveX controls in MFC if I were you. If you have VC6, the 'How do I..' in the help isn't too bad.

(Posted it in C# session but received none answer so I thought here it would be more appropriate)
Hi!
All I want is to create a BHO (Browser Helper Object) which among the other things it does, it displays something onto the IE's statusbar. The problem is how to access the rest fields of the IE's statusbar.
IWebBrowser2 gives only access to StatusText which is the first field from the 7 (as I can see in my IE).
I want to add a small icon to a statusbar field and when clicked do some stuff.
thanks,

Is there any way to simulate the press of 'ENTER' key on IE.We have a password field,which invokes a javascript function to log the user in,on press of ENTER.
We need to reproduce this action automatically - ie after filling the userid and password,we need to invoke the ENTER key.
We fill up the userid/password fields by elem->setAttribute(..,..,0),where pelem is the IHTMLElement interface.
But we are not able to simulate the press of ENTER.
Any help will be appreciated.
thanks.

Hi All,
My requirements needs me to pass an instance of a class xyz in a third party component(OCX) to my dll in ATL COM. how do i go about this?
We all know that passing parameters in the constructors of the exposed atl classes/objects is literally impossible unless i write my own atl library(oops sorry bad joke!).
That means the only option i have is to pass this third party component
instance to a method, i hope this is possible, even if it is, how do i define
the 'xyz' data type in the idl file?
<br />
import "oaidl.idl";<br />
import "ocidl.idl"; <br />
[<br />
object,<br />
uuid(AB375A74-76CB-4BBC-BFED-141791262B38),<br />
dual,<br />
helpstring("IExposedATLClass Interface"),<br />
pointer_default(unique),<br />
oleautomation<br />
]<br />
interface IExposedATLClass : IDispatch<br />
{<br />
[id(1), helpstring("method GetInstance")] HRESULT GetInstance([in] Ixyz *instance);<br />
};<br />
<br />
[<br />
uuid(3C9EB277-EC91-4E42-8CD7-34F918490B69),<br />
version(1.0),<br />
helpstring("MYDLL 1.0 Type Library")<br />
]<br />
library MYDLLLib<br />
{<br />
importlib("stdole32.tlb");<br />
importlib("stdole2.tlb");<br />
importlib("thirdpartycomponent.tlb");<br />
<br />
<br />
[<br />
uuid(4DC3999A-797D-4F9A-8955-812E87E4B6D0),<br />
helpstring("ExposedATLClass Class")<br />
]<br />
coclass ExposedATLClass<br />
{<br />
[default] interface IExposedATLClass;<br />
};<br />
};<br />
the compiler doesnt recognize the xyz data type...
i import the component(OCX) in my stdafx.h file, my idl file imports the midl compiler generated .tlb file in my library namespace, after all this when i try importing the component's idl file in my idl
<br />
import "oaidl.idl";<br />
import "ocidl.idl"; <br />
import "thirdpartycomponent.idl";<br />
the compiler reports ambiguous symbols.
what should i do?
I'd really appreciate any kind of help/suggestion here.

Hi all -
I can't find the hash_map file in VC6 STL include folder. Could somebody give me exact link from MSDN to download the ext folder, which contains this hash_map file?
Thanking in anticipation..
Misha

STL in VC6 doesn't have hash_map. At all. Not even a download from MSDN. You could a) find a third party implementation that you can drop in (I don't know of one), b) use STLport[^] (free) rather than the DinkumWare STL that comes with VC6, c) buy and use the (not free) DinkumWare[^] Standard C++ Library (this is a newer version of the one that comes with VC6) or d) upgrade to VC7.1 (VS2003), although I'm presuming that's not an option.

The Boost.MultiIndex library can do this and much more besides.

Hi,
I have a WTL app in which i have a property page based on CPropertyPageImpl.
On that page i have a Static Text Control which is basically sample of the text selected and thus labeled IDC_SAMPLE.
no i mapped WM_CTLCOLORSTATIC using MSG_WM_CTLCOLORSTATIC(OnCtlColorStatic)in a BEGIN_MSG_MAP_EX. and my implementation is a s follows :
LRESULT CItemAppearanceOptsImpl::OnCtlColorStatic(HDC hDC, HWND hWnd)<br />
{<br />
long lWndID = ::GetWindowLong(hWnd, GWL_ID);<br />
if (lWndID == IDC_SAMPLE)<br />
{<br />
::SetBkMode(hDC, TRANSPARENT);<br />
::SetTextColor(hDC, m_cfb->GetBarItemColor());<br />
::SetBkColor(hDC, ::GetSysColor(COLOR_BTNFACE));<br />
if (m_returnBrush) m_returnBrush.DeleteObject();<br />
m_returnBrush.CreateSysColorBrush(COLOR_BTNHIGHLIGHT);<br />
SetMsgHandled(TRUE);<br />
return (LRESULT)m_returnBrush.m_hBrush;<br />
} <br />
else<br />
{<br />
SetMsgHandled(FALSE);<br />
if (m_returnBrush) m_returnBrush.DeleteObject();<br />
m_returnBrush.CreateSysColorBrush(COLOR_BTNFACE);<br />
return (LRESULT)m_returnBrush.m_hBrush;<br />
}<br />
}<br />
m_returnBrush is a CBrush defined in the header and set at OnInitDialog to COLOR_BTNFACE.
now if i change the single line
m_returnBrush.CreateSysColorBrush(COLOR_BTNHIGHLIGHT);
to m_returnBrush.CreateSysColorBrush(COLOR_BTNFACE);
no change in color occurs - i.e meaning that it doesn`t work.
any ideas why? using COLOR_BTNHIGHLIGHT gives it a different look than the rest of the Page and I want a uniform UI.
thanks in advance.

Hello everyone,
I need to make Application that uses IShockwaveFlash, could anyone help me on how to check if flash.ocx (or whatever it uses) is installed, and if installed what version is installed?
|
|
|
|
|
try
CLSIDFromProgId(L"ShockwaveFlash.ShockwaveFlash", &clsid);
if this function is SUCCEEDED then flash is installed. Also CoCreateIstance can be tried to make sure.

hello friends i m converting vc .net 2003 project into vc 2005 (vc7).
i open my proj in vc2005 and then compile . i m getting following error in header file atlmisc.h file.
c:\program files\microsoft visual studio 8\vc\include\atlmisc.h(1159) : error C2440: 'return' : cannot convert from 'const wchar_t *' to 'TCHAR *'
can someone help me......
Harish

I suspect you are using WTL's version of CString. Dump the atlmisc.h, and include atlstr.h instead, to use ATL's version of CString. It might also do you some good if you upgraded WTL too.

I want to load the menu in my application from an xml on same computer.
Can any one tell me about use of xml. I am new to that sector and hardly any help is available. I found one article on code project about dynamically loading of menu
from website. but ie win32 application ,and moreover as the webaddresses have changed
it is not working. Can any one tell answer ,or referances ,orname of relevant good books.

You should ask in the XML Forum[^], not in here.
However, to save your first post being a copy of this, here's a few things to get you started.
In your stdafx.h file (or whatever you're using as a precompiled header) put
#import <msxml.dll> rename_namespace("MSXML") raw_interfaces_only named_guids
That will give you declarations for the various MS XML interfaces and such.
Secondly, you need to instantiate a document. Here's where it's a little tricky, since you have to know what version of MSXML you want to use.
CComPtr<MSXML::IXMLDOMDocument> spDoc;
HRESULT hr;
CLSID clsid;
if (SUCCEEDED(::CLSIDFromProgID(L"MSXML2.DOMDocument.3.0", &clsid)))
{
hr = ::CoCreateInstance(clsid, NULL, CLSCTX_ALL, MSXML::IID_IXMLDOMDocument, reinterpret_cast<void**>(&spDoc));
if (SUCCEEDED(hr))
{
// Yay, we have a document object!
}
}
Once you have one of those, you can load it
VARIANT_BOOL bLoaded = VARIANT_FALSE;
hr = spDoc->load( _variant_t(sourcefile), &bLoaded);
if (SUCCEEDED(hr) && bLoaded)
{
// Your document is loaded, use MSXML methods to interrogate the DOM document
// and extract your data...
}
MSDN has lots of information on IXMLDOMDocument and the other related interfaces, so dig around in there, or ask questions in the XML forum.

I design a ocx control based MFC ActiveX Wizzard,and It work and display well
and display in the test container of VC and other develop environment such as
VB.But it can‘t show rightly when I insert it to the word document.
About my ocx : A project based MFC ActiveX Wizzard , I placed a CSlider
control in the bottom of my control which was created dynamically. When drag the
slider I change bitmap from my resouces which displayed in the remainder part of
the control.
God save me! 3Q the expert provided clue or answers to the question.
