Use std::vector? It should work.

12, 12, 13
15, 14, 12
12, 34, 45 //Marks

// Marks in some test and these tests can grow up to 100 or 200

Here's my suggestion:

typedef struct
{
string s1,
string s2;
vector <float> FloatVec;
} MyStruct;

and then:

vector <MyStruct> MyStructVector;

Drag and resize support in Composite control

awaken735-Jun-03 20:40

I'm developing a kind of embeddable dialog window with all business functionality (as Composite Control)
There is an additional requirement: this control will be embedded into different applications (mostly written in VB) with different GUI layout rules. So it would be great to have possibility to rearrange and resize controls inside the Composite Control in design time.
How it could be implemented?

Hi All,

I am writing an ActiveX control and it have to work on VBA form (just my cool edit control). The problem is that the default implementation of ATL ActiveX full control refused to work with MS office VBA. (It works in any other containers like MSIE and so on)

Does anybody has an idea what's I am doing wrong? Or may be you can show me an example of the ActiveX control that can work with MS Office VBA

PS: Sorry for my poor English

ATL object in MFC project

3-Jun-03 3:29

I hope you people can perhaps help me out here. I've inserted a ATL object into a MFC project and now i want to access that object through a console application that sets certain values. My question is: What kind of ATL/COM server is created when inserting an ATL object into a MFC project. Is it a ATL Server (Exe)? or Dll?

I can't find the object in the VC++ COM/DCOM object viewer, nor is the type library registered? How can i access this interface through COM?

Any help would be appriciated.

P.S. if the question is not clear, please specify which part, so can still hope for an answer.

A COM server under ATL can be in-proc, local, or remote given that it is non-ActiveX. An ActiveX server must be in-proc.

Is the COM server registered?

Well yeah...i know that, but what kind of COM Server is it when i add it to a MFC project. I think, by the way, that's it's custom to use automation support for a MFC project, if you want to have server capibilites, but i'm still looking into that.

The type of COM server has nothing to do with ATL or MFC. If it's a DLL, then it's in-proc. If it's an EXE, it's an out-of-proc server.

ATL "PERF_AVERAGE_TIMER" counter type doesn't seem to work.

anapaula2-Jun-03 6:06

2-Jun-03 6:06

I have a problem with the ATL counter type "PERF_AVERAGE_TIMER".
I use the following code to define and increment the value of the counter. It displays always the value 1200 at the Performance monitor.

DEFINE_COUNTER(m_nAvRequestTime, "Average Time", "Help.", PERF_AVERAGE_TIMER, 0)
DEFINE_COUNTER(m_nAvRequestTimeBase, "Average Time Base", "Base Help", PERF_AVERAGE_BASE, 0)
ULONG m_nAvRequestTime;
ULONG m_nAvRequestTimeBase;
InterlockedExchangeAdd((LPLONG)&m_nAvRequestTime, nT2minusT1);
InterlockedIncrement((LPLONG)&m_nAvRequestTimeBase);

The same logic, works fine if I use C#.

Do you know if there is any problem related with AVERAGE counters in ATL?

Thanks.

Hi, I need to create a new Activex control by sub classing another Activex control. This will retain all the old functionality plus some other functions can also be added, i have tried doing it through the MFC ATL wizard, but that only create a wrapper araound it. Also MFC's ActiveX control wizard does seem to support sub classing of some MS standard controls only.
if you have a way to acheive this then please do help.

IWebBrowser2 ???

I am quite new to ATL, and I have a problem with ActiveX controls. I use ATL to create a tree control to use in web pages. I want when double-clicking on a tree item, the web browser to navigate to some predefined URL. Everything is fine until the double-click. I don't know how to get the IWebBrowser2 interface (from the current browser) and make it navigate to the URL I specify. I have found an example that creates a new browser window and tells it to navigate to the URL, but it's not what I need.
Any ideas, or suggestions...

Thanks.

Add the web browser control to your form, then query interface for IWebBrowser2.

Call IWebBrowser2::Navigate2 to goto a predefined URL.

the following project ( in c# ) shows how to provide a basic web browser.

Looks like you need to register you COM component. Go to a command prompt; change the directory to your .dll and type: regsvr32 mydll.dll. Obviously replacing mydll.dll with the name of your component. Smile | :)

IMHO, the "MY_TRIM.TrimMain" ProgID can be converted into the reasonable CLSID (say CLSID_TrimMain), but this CLSID's entry doesn't have any TypeLib information. Check the HKEY_CLASSES_ROOT\CLSID\{CLSID_TrimMain}\TypeLib key if exist.

IMHO, your library has a reference to other type library which is absent on your computer.

Icon to Bitmap conversion

Bara Sab30-May-03 2:21

Bara Sab

30-May-03 2:21

I am facing a problem in converting an icon to a
bitmap. To copy a bitmap to another bitmap following
code works fine

/*for bitmap*/
HBITMAP _hbmp = LOADIMAG(...);

//creating a source memory DC and selecting a bitmap
in it
HDC srcDC = CreateCompatibleDC(::GetDC(m_hWnd));
SelectObject(srcDC,(HICON)_hbmp);

//creating a destination memory DC and selecting a
memory bitmap to it
HDC desDC = CreateCompatibleDC(::GetDC(m_hWnd));
hBitmap =
CreateCompatibleBitmap(::GetDC(m_hWnd),75,75);
SelectObject(desDC,(HBITMAP)hBitmap);

//copies source DC to memory DC resulting in a copy of
_hbmp in hBitmap
BitBlt(desDC,0,0,75,75,srcDC,0,0,SRCCOPY);

DeleteDC(srcDC);
DeleteDC(desDC);

But if you are converting a icon to a bitmap the same
code as above does not work

/*for icon*/
//loading icon
HICON _hbmp = LoadIcon(NULL,IDI_HAND);

//creating a source memory DC and selecting a bitmap
in it
HDC srcDC = CreateCompatibleDC(::GetDC(m_hWnd));
SelectObject(srcDC,(HICON)_hbmp);

//creating a destination memory DC and selecting a
memory bitmap to it
HDC desDC = CreateCompatibleDC(::GetDC(m_hWnd));
hBitmap =
CreateCompatibleBitmap(::GetDC(m_hWnd),75,75);
SelectObject(desDC,(HBITMAP)hBitmap);

//copies source DC to memory DC resulting in a copy of
_hbmp in hBitmap
BitBlt(desDC,0,0,75,75,srcDC,0,0,SRCCOPY);

DeleteDC(srcDC);
DeleteDC(desDC);

Any comment or help shall be highly appreciated.

You don't need all that code, GetIconInfo() will return HBITMAPs for you.
