I am not sure whats wrong with your code, but this article of mine Plug-in architecture[^] should support what you are trying to do.

seems, that nobody can help me 
i have 3 main problems, i just cant solve, although they sound easy:
1. I cant change the icon of the addin button.(i always have the default button, a smiley)
(sounds like a easy problem,he? TRY IT!!!,change it to a custom icon!)
2. I cant assign a shortcut, i tried the following but it didnt worked(it compiles, but it does not assign the key)
//in the onconnection method:
SAFEARRAY arrSafe;
arrSafe.fFeatures =FADF_BSTR;
arrSafe.cbElements =35; //maby not necessary
arrSafe.cDims = 1; //maby not necessary
BSTR bstrShortCut =A2BSTR("Global::alt-s");
arrSafe.pvData = bstrShortCut;
VARIANT var1;
var1.vt = VT_ARRAY;
var1.parray = &arrSafe;
pCreatedCommand->put_Bindings(var1);
3. I would like to install my addins(the buttons) by default in a menu next to "Tools" which is called "MyAddins". how can i do this??? (i can manually make a new menu (Tools->customize,etc..) and then install my addin in there automatically (IfFailGoCheck(pCommandBars->get_Item(CComVariant(L"MyAddins"), &pMenuBarCommandBar), pMenuBarCommandBar);
but i cant make this "MyAddins" Menue automatically by code!!
THE FIRST DUDE, WHICH CAN HELP ME IN ANY OF THE 3 ISSUES (ISSUE 2. IS THE EASYEST, I GUESS)

I need to have more than one view in my application
so I have wrote the following function.
void CMyDoc::CreateAllViews()
{
CCreateContext l_Context;
l_Context.m_pCurrentDoc = this;
CView* l_pActiveView = g_pMainFrame->GetActiveView();
::SetWindowLong(l_pActiveView->m_hWnd, GWL_ID, 0);
l_Context.m_pNewViewClass = RUNTIME_CLASS(CRilevamentoDatiView);
m_pRilevamentoDatiView = (CRilevamentoDatiView*)STATIC_DOWNCAST(CView, g_pMainFrame->CreateView(&l_Context));
l_Context.m_pNewViewClass = RUNTIME_CLASS(CStatisticheView);
m_pStatisticheView = (CStatisticheView*)STATIC_DOWNCAST(CView, g_pMainFrame->CreateView(&l_Context));
l_Context.m_pNewViewClass = RUNTIME_CLASS(CFiltriView);
m_pFiltriView = (CFiltriView*)STATIC_DOWNCAST(CView, g_pMainFrame->CreateView(&l_Context));
l_Context.m_pNewViewClass = RUNTIME_CLASS(CConfigurazioneView);
m_pConfigurazioneView = (CConfigurazioneView*)STATIC_DOWNCAST(CView, g_pMainFrame->CreateView(&l_Context));
}
The problem is the following:
views creation is ok but all of them looks like the last one created
in my function.
Is it possible to have multiple views in a SDI project ??
Does someone knows why my function doesn't works ???

I need to have more than one view in my SDI project.
I'd prefer to don't create a new view and destroy the old one
any time I have to change view.
I'd prefer to create all my views at the creation of the application
and to manage them into an array (statically).
Is it possible to do that ???
I have wrote this function:
void CMyDoc::CreateAllViews()
{
CCreateContext l_Context;
l_Context.m_pCurrentDoc = this;
CView* l_pActiveView = g_pMainFrame->GetActiveView();
::SetWindowLong(l_pActiveView->m_hWnd, GWL_ID, 0);
l_Context.m_pNewViewClass = RUNTIME_CLASS(CRilevamentoDatiView);
m_pRilevamentoDatiView = (CRilevamentoDatiView*)STATIC_DOWNCAST(CView, g_pMainFrame->CreateView(&l_Context));
l_Context.m_pNewViewClass = RUNTIME_CLASS(CStatisticheView);
m_pStatisticheView = (CStatisticheView*)STATIC_DOWNCAST(CView, g_pMainFrame->CreateView(&l_Context));
l_Context.m_pNewViewClass = RUNTIME_CLASS(CFiltriView);
m_pFiltriView = (CFiltriView*)STATIC_DOWNCAST(CView, g_pMainFrame->CreateView(&l_Context));
l_Context.m_pNewViewClass = RUNTIME_CLASS(CConfigurazioneView);
m_pConfigurazioneView = (CConfigurazioneView*)STATIC_DOWNCAST(CView, g_pMainFrame->CreateView(&l_Context));
l_Context.m_pNewViewClass = RUNTIME_CLASS(CDatiAnamnesticiView);
m_pDatiAnamnesticiView = (CDatiAnamnesticiView*)STATIC_DOWNCAST(CView, g_pMainFrame->CreateView(&l_Context));
l_Context.m_pNewViewClass = RUNTIME_CLASS(CModInterazioneView);
m_pModInterazioneView = (CModInterazioneView*)STATIC_DOWNCAST(CView, g_pMainFrame->CreateView(&l_Context));
}
But It doesn't work... views creation ends with success but when I try
to show a view it looks like the last view created by my function...
All views created by my function, lokks like the last one created !!!
Does someone knows which is the problem ??? Or can supply me any other
information in order to have multiple views in my project ???
Thanks a lot

How To Detect Proxy Settings and Manipulate them for Internet connection ?.
I am using Sockets For communication between PC's
|
|
|
|
|
For IE, use InternetQueryOption and InternetSetOption, but be aware proxy settings don't have any effect on your sockets (maybe you're mixing proxies and gateways?)

Sir, can you tell me why the following code not works in VC++ 7.0
std::hash_set<std::string> myhash;<br />
myhash.insert("string");
Strange that it works if we use std::set instead of std::hash_set
|
|
|
|
|
In which sense doesn't it work? Compiler error, crash at run-time? With some more info maybe I can be more helpful.

Dear Joaquín i require little help. The question is related to std::set
I am doing something like this:
std::hash_set<std::string> myset;<br />
std::string country="india";<br />
<br />
myset.insert(country);
But the code above is not working on my VC++ 7.0 compiler. I am getting an error. I am copying below:
c:\Program Files\Microsoft Visual Studio .NET\Vc7\include\xhash(38): error C2440: 'type cast' : cannot convert from 'const std::string' to 'size_t'
|
|
|
|
|
Are you sure you've inserted the appropriate #include <string>? Other than that, I cannot figure out how such a simple piece of code is causing the compiler to go awry.

Sorry, actually the code above is working, but if i use std::hash_set instead of std::set, it does not work. I am writing code below:
using namespace std;
int main(int argc, char* argv[])
{
string name = "india";
hash_set<string> val;
val.insert(name);
return 0;
}
The error i am getting is:
c:\Program Files\Microsoft Visual Studio .NET\Vc7\include\xhash(38): error C2440: 'type cast' : cannot convert from 'const std::string' to 'size_t'
Yes i am including all the required headers.

I use function a lot and it works perfect. Recently , by chance i finded out
there's a problem in win98 ( second edition ) when using 16 BIT COLOR.
Here's example of how i use this function :
DrawTransparentBitmap(
m_hMemDC ,
HBITMAP(pictBubble),
nBubblePosX,
nBubblePosY,
CLR_TRANSPARENT);
Here's my define of transparent color ( "clean" CYAN )
#define CLR_TRANSPARENT RGB(0,255,255)
As i said , it works everywhere except win98 ( second edition ) when using 16 BIT COLOR.
As far as i know , each loaded image produces it's own palette. In some cases , it can
cause color to be changed to nearest color and obviously , transparency won't work in this
case since above function needs transparent color to be exact down to pixel.
So , i tried to use following to work it out :
cTransparentColor = GetNearestColor( hdc , CLR_TRANSPARENT );
But , it didn't work.
Need your help ( it's pretty urgent ) , thanks !
P.S. I just prefer solution that won't force me to change everything , but a small patch

I have to get the Bitmap of a HTML page,without displaying it .
The class used to load HTML is CDhtmlDialog .This is the sample code
CDhtmlDialog key;
Key.Navigate(fileName,0,NULL,NULL,NULL,0);
Key.SetWindowPos(this,rect1.left,rect1.top,rect1.Width(),rect1.Height(),SWP_SHOWWINDOW);//OK working
CDC * pDc=Key.GetDC();
HDC htmlDC=pDc->GetSafeHdc();
//create a sample image
CImage dest;
if(dest.CreateEx(118,88,24,BI_RGB,NULL,0)==FALSE)
{
AfxMessageBox("Error in extracting the Keyframe");
return FALSE;
}
HDC destDC=dest.GetDC();
SetStretchBltMode(destDC,HALFTONE);
//copy the
if(StretchBlt(destDC,0,0,118,88,htmlDC,0,0,rect1.Width(),rect1.Height(),SRCCOPY)==FALSE)
{
AfxMessageBox("Unable to Extract Key Frame");
return FALSE;
}
Now the problem with this is that the BItMap is not of the HTML page but of the application Mainframe window !!!!!!
