may be this help u... Smile | :)

u may have dialog class like,

C++

CPageSetupDialog abc;
//Conding to set values.
abc.papersize = 10;
abc.sorce = "ACC";
abc.margin = 44;
//ETC.
//And then modal it..Like,
if(abc.DoModal() == IKOK)
{
//Success;
}else
{
//Fail..
}

Locating a function address with the debugger

I need to debug a program for which I do not have the source code.

I want to place a breakpoint at the CreateFile() Win32 API.

I have told Visual Studio to load the symbols for KernelBase.dll and Kernel32.dll .

Now how can I tell the Disassembly View to take me to the location of CreateFile()?

Thanks in advance.

The difficult we do right away...

Visual Studio is not the right tool for reverse engineering. Use IDA Pro or OllyDbg. IDA Pro is damn expensive while OllyDbg is free. A lot of reverse engineering guys use these.

I'd use WinDing, set up a symbol server and place a breakpoint directly on CreateFile. No need for disassembling.

Using WinDbg try these two commands:

bp kernel32!CreateFileW

Take a look at Microsofts public symbol server. You can download symbols for all their code from it, and set breakpoints and so on.

You can speciyf these sylbols in VS and when it tries to load downloads them automatically. I use windbg though so I cant help you much more than that, and I work in the kernel, but if you choose to do the same this is a usefull command:

bp nt!ntcreatefile "dt nt!_UNICODE_STRING poi(poi(@esp+0xc)+0x8)"

It sets a break point on createfile (this is what CreateFile maps to in the kernel) and displays the file being opened (This is 32 bit, if it was 64 the parameter would be in a register not on the stack).

SO any user mode acces to creatfile you can break on and have a wander arond the stack and see whats doing what.

--edit--

Or as the poster above says, set the bp in the usermode dll.

I can deffinitely recomend using windbg, it is a hell of a debugger, everyone in microsoft uses it, VS is a toy in comparison.

==============================

Nothing to say.

Yes, but I have shyed away from it due to its complexity. I guess I'm just a dumb "user" at heart.

Maybe this will encourage me to try it. Smile | :)

It is complex and command driven rather than UI driven, but what a command set! It can do amazing things.

I use the IDE's debugger when I can cause it's convenient and easy to use, but the second things get even a little complex I break out WinDbg.

My system is win7 64Bit
I use the VS2008 to compile the chrome solution. But I meet some problem about compile the FFMPEG.
I google that the others are all ok when compiling, but I have bad luck. I donot know why some error happen.
Does anyone meet the same problems?

CTreeCtrl, CDockingPane, and mouse events

Rob Bryce15-Mar-13 21:33

Hi All, many thanks up-front to anyone who can help here.

I have a client that wants me to migrate a CTreeView-derived class to one which works like a docking pane. The class is so large now that it's not feasible to rewrite everything.

So...I still have the underlying CTreeCtrl-derived class (more/less untouched), which is a child of a class derived from CDockablePane (migrated from the CView class). I've also derived from CMultiPaneFrameWnd (used when the pane is floating) to try to trap events.

I've got it working about 80%. I need help/direction with the other 20%. I've got the CDockablePane derived class working with bulk of the MESSAGE_MAP events (menu handlers, ON_UPDATE_COMMAND_UI, etc.) working correctly. The events associated with the mouse are giving me grief.

I see 3 standard modes for the dockable pane: floating, docked, and tabbed. And they all behave differently w/r to mouse events - and depending on the docking mode.

For example:
* If the docking mode is DT_SMART *and* the pane is NOT floating, then drag&drop and double-clicking work correctly.
* If the docking mode isn't DT_SMART, then drag&drop usually tries to drag the complete docking pane instead of working correctly (regardless of floating, docked, tabbed).
* When the pane is floating, I can't trap WM_LBUTTONDBLCLK (unless you click on the lines and little [+] boxes...) or the respective notify or reflect messages - even Spy++ doesn't record them. I just don't see any left button double-click events - at all!

Google searches show that I'm not the only one with these types of issues. I've read and tried pretty well every suggestion...and I still have these issues. I'm now concerned about bugs or assumptions in the framework after reading this:
http://connect.microsoft.com/VisualStudio/feedback/details/641096/cdockablepane-calls-releasecapture[^]

This link: http://www.johnbyrd.org/blog/index.php?itemid=405[^] helped a lot but didn't solve all issues either.

I can also replicate these issues (unable to trap double-clicking when floating) in the VisualStudioDemo feature pack demo.

Any suggestions on how to get a CTreeCtrl to work inside a CDockingPane - consistently - would be really appreciated. I feel that many issues are related to CMultiPaneFrameWnd, but can't resolve them.

Thanks!

Hm... My trees can register the double clicks in their floating panes Smile | :)

For example, it is possible to extend a node by the double click at its item...

The model in my case is (from outside): CXDocablePane->CXFrameWndEx->CXTreeCtrl Smile | :)

They sought it with thimbles, they sought it with care;
They pursued it with forks and hope;
They threatened its life with a railway-share;
They charmed it with smiles and soap. Smile | :)
