Try handling the WM_ERASEBKGND message instead of OnPaint()

by the way..
i don't think that you normally force redrawing of anything in mfc with sending WM_PAINT - messages to the window.. you normally Invalidate that window (controls are windows too).. then it is forced to redraw itself.
m_edit.Invalidate();
i am no expert, but i think this is the proper MFC way.

Make sure that you have the CS_CLIPCHILDREN style set for your dialog. When you ask for a DC for that window, it will automatically clip the children rectangles from where you are allowed to paint, and you will no longer paint over your controls.
You can set this style for your dialog after it has been created by doing this:
LONG lStyle = ::GetClassLong(hDlg, GCL_STYLE);
lStyle |= CS_CLIPCHILDREN;
::SetClassLong(hDlg, GCL_STYLE, lStyle);
By the way, you should paint the bitmap in the WM_ERASEBKGND message instead. This will reduce any flicker that may appear, and it is a fundamentally better place to perform that action.

I've created a dialog based application and i've put a WebBrowser control inside.
The application fails to create the dialog and i would like to know how to fix the bug.

Can you be a bit more specific ?

Is it in the main dialog or what ?

Is not about an error.
The execution of dlg.DoModal(), where dlg is the main dialog, simply has no effect.

When you created your app using appWizard (i'll assume) did you specify ActiveX controls...?
Did you add the control as an activeX control...?

No, i didn't specify "ActiveX controls".
Meanwhile the application has grown and i have to add the control without the wizard's support.

Thats probably whats causing your problems than.
It's not too much work to add activeX support though.
Create a small test app WITH activeX support and just find the functions.
AfxOleInit or something I think similar to this...probably a few more things too.

I have tried this.
The only difference i found is "#include afxdisp.h" in stdafx.h, which has no effect in my current application. It has to be something else.

It's always a pain to add options like ActiveX after the project has been created.
I would suggest using app wizard..much quicker and easier.
Create a new project using AcitveX controls and just copy your old code over into the new project.

Unfortunately, this seems to be the only option for the moment.
Thanks!

If nothing else is working...you might as well and see if it helps...
This can be a pain in the a$$ I know...especially if your like me and you modify and remove all that MFC junk comment shite. However consider yourself lucky your not in dos and take full advantage of the windows clipboard.
Lemme know how it turns out...i'm curious to know if thats whats wrong.
Cheers!

When i created the test application i missed the line
AfxEnableControlContainer();
in the application's InitInstance() method.
Adding this will make the stuff just "running like hell".

There is a addin (at least under VC++ 6 there is)
Project - Add To Project - Components and Controls
In the Visual C++ Components folder find ActiveX Control Containment Component
This should make your WebBrowser work.

To fix this problem I dynamically create (using the new operator) the web browser control member variable in my OnInitDialog()
This fixes the problem for me.

_bstr_t str;
str= "SELECT * FROM Tennis ORDER BY Name";
if( pDoc->m_pConnection==NULL )
return ;
_variant_t vRecsAffected(0L);
try
{
pRecordSet = pDoc->m_pConnection->Execute( str, &vRecsAffected, adOptionUnspecified);
.
.
.
I recevie run time error for Execute() line,in output window:
Exception thrown for classes generated by #import

Also:
When I debug that line for str I see that it is "Bad Ptr" and "CXX0030: Error: expression cannot be evaluated".
So there is a problem with that?Does anybody know whats that?

In my experience, when you get a bad args error, it's more than likely that it's your SQL that's at fault. How about:
SELECT * FROM [Tennis] ORDER BY [Tennis.Name]
Just a guess...

i declare a function pointer like this:
void (*PTestFunc)(CString& str);
and two classes:
class CTest
{
...
void Test()
{
m_pTestFunc(CString("fdsaf"));
}
void SetFuncPointer(void* pointer)
{
m_pTestFunc = pointer;
}
PTestFunc m_pTestFunc;
...
}
class CMyClass
{
...
CString m_strCaption;
void MyTest(CString& str);
void Init(CTest& test);
...
}
CMyClass::MyTest(CString& str)
{
m_strCaption = str;
}
void CMyClass::Init(CTest& test)
{
test.SetFuncPointer((void*)MyTest); //error c2440
}
//////////////////////////////
if i add "static" before MyTest, it is right;
but u see i need this pointer in my class, i can't set MyTest static. so how to solve this problem? does c++ define the class member function pointer?
c++ : my dream
