- Adding a new enumeration adds the enumeration to the header-file of my ATl-Project, but does not add the enumeration to the *.tlh-file of the client, neither I can observe a change in the OleView.
Does anybody know what causes this behaviour or how to implement a workaraound?
The TLB contains only those types which are defined or mentioned (directly or indirectly) inside [library] block in IDL file.
So inside [library] block there should be something which refers to SensorStatus enumeration.

Thank you for this advice. I didn't know that I have to use an enumeration which I have declared in the idl-file.
Now its working.

Hi,
I'm sure this is probably the easiest question in the world but I can seem to find anything anywhere about how to do it. Basically I have created a dialog in an MFC program, but it is a fixed size, I want the user to be able to resize it, how do I do this?
Cheers

In the resource editor, open the properties for your dialog and select the Border style to be "Resizing". You will then need to handle the WM_SIZE message in your dialog's code (use ClassWizard) so that you can handle the resizing/repositioning of any child controls when the dialog is resized. This is a pretty common problem when using dialogs under MFC and there are a boatload of solutions, many of them on here. I recommend searching for Paolo Messina's dialog resizing solution which works nicely.
Hope that helps...

Thanks alot for that, knew it had to be something faily simple, that sorted it staight away. Cheers for help, much appreciated!

This might prove useful:

It'll save you the trouble of manually repositioning controls in response to WM_SIZE messages.

Hi.
I'd like to change dialog's class name from "#32770" to "MY DIALGO".
I used following code in WTL. But it doesn't work
WNDCLASSEX wndClass;
::GetClassInfoEx((HINSTANCE)_Module.GetModuleInstance(), "#32770", &wndClass);
wndClass.lpszClassName = _T("MY DIALOG");
::RegisterClassEx(&wndClass);
would somebody gave me a solution?
Thanks. Have a good day....

Hi,
I am creating an com addin for Office using VC++. The project is ATL based. My question is how can I implement a common handler for a set of CommandBarButtons?
Thanks in advance

The sink map basically provides the mapping between a dispid that defines the event and the member function that handles it. Command button fires the event with dispid 0x01 so there is no need to setup sink map for every button.
BEGIN_SINK_MAP(CAddin)
SINK_ENTRY_INFO( 1,__uuidof(Office::_CommandBarButtonEvents), 0x01,OnClickButton,&OnClickButtonInfo)
END_SINK_MAP() You can differentiate button's with the help of button value or caption.
void __stdcall CAddin::OnClickButton(
IDispatch* Ctrl,
VARIANT_BOOL * CancelDefault)
{
USES_CONVERSION;
CComQIPtr pCommandBarButton(Ctrl);
MessageBox(NULL, "Clicked", "OnClickButton", MB_OK);
}
Knock out 't' from can't,

Hello folks,
I have been trying to pass array of string from my ATL component (I'm using VC++ 6) to VB.
Basically I have a vector of strings in my ATL component which I need to pass to VB.
I have been reading and confused about using either VARIANT *Array or SAFEARRAY *Array in my IDL declaration. Are they the same?
Anyway would somebody gave me an example on how to do this as well as the calling sample from VB code?
Thanks in advance

A SAFEARRAY is one of the things a VARIANT can contain.

No they are not the same. As Christian says, a SAFEARRAY is one type which a VARIANT may be. The reason for the confusion is because lesser languages such as VBScript don't know how to handle SAFARRAYs in the interface declarations - it can only handle VARIANTs. That's why SAFEARRAYs are passed as VARIANTs.
It's odd. VBScript knows how to deal with SAFEARRAYs internally, but it doesn't understand it in interface declarations.

Hi All,
I am getting my IE crashed when I try to use ActiveX component. Here is the scenario.-
The main thread Creates a Worker thread in suspended mode. Then the main thread invokes the Dialog box UI. In the InitDialog( ) method of the UI, i resume the functioning of the worker thread I created earlier. This is achieved by using the Pointer to thread as a static member.
The worker thread does lengthy processing and keepes updating UI by Sending messages to the UI thread. I use SendMessage( ) method for this.
I have provided a button quit the processing in between. I make a static Boolean variable TRUE when user clicks the ABORT button. The worker thread calls a static method which periodically checks for this condition to become TRUE. When this condition becomes TRUE, I terminate the worker thread by using AfxEndThread() function.I need to make sure that the UI closes before the worker thread is terminated. So I define a user defined Message and send it to UI thread and In its handler code I close the Dialog box.
The the main thread resumes and does rest work.
This is an ActiveX component invoked from IE. When the component is invoked for the first time, it works fine, but on second run the IE crashes.
Also this crash is reproducible in Release mode only and not in Debug mode.
I am providing the stack trace also for this, which i got when I debug it in Release mode.
Thanks,
Amit.

I'm not an MFC guru in any way, but something that I've picked up from other threads, is that if an function within an MFC DLL is called, one's supposed to call AFX_MANAGE_STATE() first inside the function.

Hello everybody,
I am developing a Browser Help Object in IE and encounter some problems:
- Get data sent by POST method from an URL.
- Send data to an URL by POST method.
How can we accomplish that? Do you have any idea?
Thanks.

I have a Class called CDriver which is as follows:
class CDriver {
public:
// Constructor
CDriver();
CDriver(CDriver &driver); // Copy constructor
CDriver operator =(const CDriver d);// Assign one to another
~CDriver();
// Varables
CString csFirstName;
CString csMI;
CString csLastName;
CString csBirthDate;
CString csASSN;
CString csStreetAddr;
CString csCity;
CString csState;
CString csZip;
CString csHomePhoneNum;
CString csHireDate;
CString csTruckAssigned;
};
Now I made a vector: "vector<<cdriver>> vecDriver"; Also a CString vector: "vector<<cstring>> myCStringvec"; and an iterator "vector<<cstring>>::iterator myIT";
None of these work properly! I can get the "myCStringvec.push_back(temCString)"; to accept one and only one CString. I NULLed temCString before reloading it with data then again used: "myCStringvec.push_back(temCString)"; to no avail. WHY?
vecDriver doesn't work at all nor does myIT. Please ignore the "<< and >>" it would not show what I wanted to show without using two each!

Shouldn't your copy constructor be declared with const CDriver& driver as a parameter?
I've used vector<cstring> before with no problems; what version of VC++ are you using, and which version of CString (WTL or ATL)?

VC++ 6.0 verson. yes you are right about the copy constructor. I (the vector has the problem) have a problem with the CString(s) that make up CDriver data. This is my first project using the STL. I'm tring to do everything by the book "C++ from the Gound Up", H. Schildt.
In debug mode I check the loading of the CStrings and sometimes it will load correct (itself) and other times it only loads partially. The vector will only load oned CString using the push_back() method; even when I see in debug that the CString IS LOADED but the vector ignores the passing of the CSting the second time.
Any ideas?

Does this fragment work OK?
std::vector<CString> temp;
temp.push_back(CString("ABC\n"));
temp.push_back(CString("DEF\n"));
temp.push_back(CString("GHI\n"));
std::vector<CString>::iterator it;
for(it = temp.begin(); it != temp.end(); ++it)
{
ATLTRACE((LPCTSTR)(*it));
}
Should print ABC,DEF,GHI on successive lines....
