Sorry I didnt understant that.

Can you show how you create the tab? Is it placed in the resource or dynamically created??

1)I've included the tab control on the dialogbox.
2)In class that implements the the dialogbox has a member CTabCtrl m_Tab.
3)The .cpp class of this dialogbox has following code.

CoInitialize(NULL); <br />
<br />
	EnableThemeDialogTexture(GetSafeHwnd());<br />
		<br />
		<br />
	char szBuffer1[50];<br />
	char szBuffer2[50];<br />
<br />
	strcpy(szBuffer1,"Login");<br />
	strcpy(szBuffer2,"Upload");<br />
<br />
	m_Tab = (CXPTabCtrl *)GetDlgItem(IDC_OPTION_TABS);<br />
	<br />
<br />
	TCITEM tcItem1 = {0};<br />
		<br />
	tcItem1.mask = TCIF_TEXT;<br />
	tcItem1.pszText =szBuffer1;<br />
	tcItem1.cchTextMax =79; <br />
<br />
		<br />
<br />
	TCITEM tcItem2 = {0};<br />
		<br />
	tcItem2.mask = TCIF_TEXT;<br />
	tcItem2.pszText =szBuffer2;<br />
	tcItem2.cchTextMax =79; <br />
<br />
	m_Tab->InsertItem(0,&tcItem1);<br />
	m_Tab->InsertItem(1,&tcItem2);<br />
<br />
	m_Tab->SetCurFocus(0);

I hope you have tried with out calling this function also.

Coudnt find any problem with this code. Any way pls try specifying the ETDT_ENABLETAB in the EnableThemeDialogTexture() function.

How to get gdi objects associated with a CDC object?

I've tried for specifying ETDT_ENABLETAB but that doesn't has any effect.
What should be done?

There are functions like GetCurrentBitmap(), GetCurrentBrush()... but how do we know what objetcs are attached to the cuurent CDC object?

Actually I want to check the GDI objects associated with CDC object and delete all the objects using DeleteObject()

Expecting favourable answers.

Nope, AFAIK. Anyway selecting a new object gives the (previously) current object back to you.

Doesn't make much sense ...

If you don't own the objects selected into the DC, then you shouldn't
be deleting them.

If you own the objects then you already have the previously selected objects
which you should select back into the DC before destroying the objects.
At least that's what you SHOULD be doing Smile | :)

Using MFC class in a native application [modified]

Hi,
I had develop some MFC calss and that program is working properly. Now I am decided to integrate my MFC class with .NET (C++/CLI).
My requirement is that, I want to use the same MFC class in my C++/CLI Program with out any changes. I can do it like this, I create a .dll file using the same MFC calss in load that .dll file into my C++/CLI ( CLR ) project and create an object using that .dll file and it is working. But I am not satisfied in this methord. Because, through this method, we want to keep a lot of .dll file ( for each class we need to create .dll file and load that .dll file in to my new project ). So I am trying for another method. So I made changes in my mfc project settings and inherit the mfc class in my native class and create an object using the new native calss and i can load the MFC class in my native class and I can call the functions from my native object. But in my MFC class there has a function OnCreate(LPCREATESTRUCT lpCreateStruct). in that function I had do some steps. I can't call that function through the native call. Can you help me to solve this problem?
My aim is using my existing MFC class, I want to create a create a native application ( C++/CLI )

my source code is like this,

Sorry mate, but I think you are going to get very few answers to your question. At least not if you don't reformat your code with the < pre > < /pre > tags and use the debugger to isolate where the problem is and then paste important code. With such a hugh snippet...

Up to you

As Nelek said, you're not going to get people wading through that long code. Certainly not me. You need to read the positing guidelines. The bit about the pre tags are there for a reason. To help you to help us to help you.

To solve your own question, you need to set a bunch of breakpoints and see if your OnCreate is even getting called - then whether your Tree is getting created, and has a HWND, etc. You don't actually check for creation of the tree, you just call the create function.

I'd be quite surprised that you can get an MFC window object fully working in a non MFC environment - especially a CView derivative, which uses a lot of the MFC plumbing.

Worst comes to the worst, and you want to keep the same code for both projects, you can #ifdef different bits for MFC and for CLI.

Good luck,

Iain.

I need to draw the child controls (Combobox and other custom controls) into a metafile. Following is the code,

...........
CMetaFileDC mDC;
mDC.CreateEnhanced(DC,0,0,_T("Graphics\0Picture 1\0\0"));
............
HWND hWndChild = Cal.GetSafeHwnd(); //Child control
::SendMessage(hWndChild, WM_PAINT, (WPARAM)mDC.m_hDC, 0L);

The child control gets drawn, but I'm not able to specify its position and size. It is always drawn at the top.

Is there anyway to specify the size and position of the child control while drawing into a metafile DC?

ShilpiP13-May-08 21:27

13-May-08 21:27

I am not very sure but i think because you pass argument "0" at lpBounds (third position) of CreateEnhanced

lpBounds
Points to a RECT data structure or a CRect object that specifies the dimensions in HIMETRIC units (in .01-millimeter increments) of the picture to be stored in the enhanced metafile.

13-May-08 23:47

Even if give the third parameter lpBounds, (CreateEnhanced) in HIMETRIC, it is not working.

Basically, I have a activex control with some drawings on the client area and a combobox in the middle. I need to get all these in the metafile.
When I call PlayMetafile to check the metafile contents, the combobox is always drawn at top instead in the middle.

When control recieves a WM_PAINT message, how will the control know where it should draw itself?

How do you force a control to draw itself into a given device context and also specify in which position it should be drawn?
