CPropertysheet and tab ctrol

Did you add a .def file to your project that exports the DllRegisterServer function
(or did the sample code include a def file that you need to add to your project)?

Hi,

I have a property sheet (in wizard mode) and on one property page of this sheet, I have a pop up dialog.

This pop up dialog has a tab control which is again showind a child dialog (no border, style = child).

So the picture looks like this

Property Sheet
Property Page launches
CMyDialog (pop up)
CMyDialog has CTabCtrl and Child dialog to show on the tab.

This child dialog doesn't receive any messages. If I click on the dialog, nothing happens. Tabs get changed though.
I am wondering if its a focus problem? how should i fix it.

The code to add this child dialog with the tab control looks like this

Init of Tab Control :

Tab Contrl->Add tabs;

Create a vector of dialogs

Instantiate the dialog class, add it to vector

Create and Repos the dialog window, and say ShowWindow.

Thanks in advance,
Misha

Can you show the actual code you use to do this?

Hi all
I am using debuggin API for my purposes.
After I have initialized everything correctly each time I use StackWalk64 function it doesn't work.
Evenet if it returns TRUE I can see on the debug output

First-chance exception at 0x00000000 in TestMyStackTraceDebugger.exe: 0xC0000005: Access violation reading location 0x00000000.

I notice that the CONTEXT returned is almost all set to 0 and data returned in STACKFRAME sturcture are all 0.

What is wrong?
Each of the following (in order) was successful returning TRUE

-CreateProcess //with Debug permission
-WaitForDebugEvent
-OpenThread

CONTEXT ctx;
memset( &ctx, 0, sizeof( CONTEXT ) ); //init struct!
HANDLE threadHandle = OpenThread( THREAD_GET_CONTEXT , FALSE, de.dwThreadId );
GetThreadContext( threadHandle , &ctx );
-GetThreadContext
-SymSetOptions
-SymInitialize

STACKFRAME64 sf;
memset( &sf, 0, sizeof(STACKFRAME64));
sf.AddrPC.Offset = ctx.Eip;
sf.AddrPC.Mode = AddrModeFlat;
sf.AddrStack.Offset = ctx.Esp;
sf.AddrStack.Mode = AddrModeFlat;
sf.AddrFrame.Offset = ctx.Ebp;
sf.AddrFrame.Mode = AddrModeFlat;
#endif

StackWalk64(
IMAGE_FILE_MACHINE_I386,
gamerProcess,
threadHandle,
&sf,
&ctx,
NULL,
SymFunctionTableAccess64,
SymGetModuleBase64,
NULL );
Kind Regards

Did you use your debugger to see where the code crashes exactly ? Check the state of the different variables to see if everything looks OK.

Why didn't you set the ContextFlags member of CONTEXT.
Is the thread in suspended mode, as recommended by documentation?

Probably the CHideAndSeek() class should help?

Seriously though, what is your requirement?

Will the ShowWindow() API help you?

Use a combination of SetWindowPos and/or MoveWindow to grow/shrink said window; thus show or hiding a portion of the dialog.

MESSAGE MAP Optimization

Will the compiler optimize the MESSAGE MAP of each class?

Or else, I'd better rearrange it by putting high-frequent messages at top of the array.

How could the compiler know which messages occur with more frequency?

I guess he supposes the compiler optimizing message handling on position (in the MESSAGE_MAP list) based mechanism, this way the developer could suggest the compiler itself what will be the more frequently used message.
