draw method of activex

HI Gurus,
Is it possible to attach a dialog class in the draw method of activx ctrl class?

Code:

---


void CRotaryCtrl::OnDraw(CDC* pdc, const CRect& rcBounds, const CRect& rcInvalid)

pdc->......//(attach an cdialog subclass)

---

thanks

Please elaborate on "attach". It can mean different things, so it's good to hear from you instead of guessing

By attach i mean, i have a dialog class which I created in the activex project which has combobox, edit box etc.
I want to display this dialog box in the activex control draw method.
Is it possible?

It is possible, but not the right approach. Draw is for drawing , not for creating dialog box.

Is this what you're trying to do?

Exactly Mike, that's what i am trying to do.
But when i do exactly what the article says i get error :winocc.cpp line 307. Basically it doesn't like the movewindow method. I tested the control using visual studio activex test control container. Tried with IE as the article says same error message.

Any suggestion?

It's probably a timing issue. That error indicates that the window is not valid at that time. You may need to restructure the sequence of code that creates the control.

hi! You are right. I was trying different things,i put the code to create the dialog in the constructor of the control and it wouldn't error now and it wouldn't display the content of my dialog also.

Code:

---


CReportXCtrl::CReportXCtrl()
{
        InitializeIIDs(&IID_DReportX, &IID_DReportXEvents);
       
        // TODO: Initialize your control's instance data here.
        m_reportDlg.Create(IDD_XDIALOG , this);
}

no changes in oncreate.
in draw method the same as the article says....

Code:

---


m_reportDlg.MoveWindow(rcBounds, TRUE);

---

This is surely more than jsut vc2003 and vc2005 issue... can't believe i am having problem one after another. Has anyone made a dialog frame to display in a mfcactivex ctrl porgram?

I'm using Visual Studio 2005 and I followed the sample program in the article above. I was able to build and display the control in the test container. Make sure you set the resource flags for the dialog as stated in the article.

That's strange. I tried again exactly with the resources and everything mentioned. Didn't work. Point no 5. says using classwizard create oncreate(wm_create) , i don't know if it sounds silly. But i created a virtual OnCreate(LPCREATESTRUCT lpCreateStruct) in the ctrl.h and cpp and added the code.
Here is a .h and .cpp file as i can't attach the entire project(too big). if you can help to find out what is wrong.
thanks

Two differences:

My code uses afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct); as a public message handler. And,

I include OLEMISC_SIMPLEFRAME for the control type information.

Corrected the virutal to afx_msg...that was a silly mistake.
isn't OLEMISC_STATUS for ATL activex ctrl... i tried to add it, but the compiler complains. I believe i need to add the atl header files. Documentation says OLEMISC_SIMPLEFRAME(miscstatus) but my code is happy with void. Bit confusing. Also if i try with the second addition, the activex container complaines there is an unknown error. Not easy isn't it?

Actually, it was easy for me. I used the project wizard to create the skeleton code. The "frame" option was provided via the wizard. The only changes I made were those recommended by the article.

I used the project wizard too, mfc activex control wizard. If i edit just the first part you mentioned, making it afx-msg, my container says unspecified error(i wrongly wrote only after the second addition). I wish i could get this done.

Would you mind attaching me the .cpp and .h ctrl ? I tried again now and i get the old winocc.cpp 307 error again .... strange.

As requested...

HI Mike, Thanks for the file. While comparing your files with mine, I noticed that enable simple frame wasn't a default in my wizard. I tried creating another control with that ticked, and i still get the winocc.cpp 307 error...

What version of Visual Studio are you using? I created my test program using Visual Studio 2005.

vs2005 and vc++2005. I tried in my vmware which has vs2008 beta.... i get the same error message when i attach the activex.

I have a feeling it's my computer libraries which is causing this problem. I wish i know what?

When i try to debug the error in vs, it goes to afxwin2.inl line 104 (movewindow() function). And the values of lpRect->left 0, top->0, right -50, bottom-50, so nothing wrong with the values ibeleive. and cwnd::movewindow from winocc.cpp line 307

Code:

---

assert(::ISWindow(m_hwnd) // I can see it says expression can't be evaluated.

---

I believe that's where the problem starts or rather ends.

THanks

Hi,

I'm trying to do the same thing demonstrated by the article:

But keep getting errors, i'm using vs2010, my project is identical as the one posted here, did you guys figured out what was the problem?

Thanks in Advance!

Hello,

After few days researching i've found out the solution.

The ActiveXCtrl must be a Control Container, this setting resolve the problem:

Put AfxEnableControlContainer() right before the creation of the attached control in the handler of WM_CREATE (::OnCreate).

Cheers!

It must not, in case your dialog styles include WS_CHILD. See the sample as a proof.

Well, if you're saying.

I'm shallow at mfc development, just posting what works out for my problem.

But anyway thanks for the correction! i'll try not to misguide people (unwittingly) again, haha.

Thanks for the post link, this will surely help me with other issues.

Cheers!
