Hi
I have a question regarding map file please help me

I made a release version of an application with map file so that if my application crash I easily pinpoint out the function/s causes that problem. Unfortunately the Crash address that I get is not included in the map file that Ive created, it seems that the preferred load address of my Map file is 0x00400000 and all the crash address that I have are startin 0x006...

I hope you could help guys

waiting for your response ASAP

Sure that the crash reported from your exe/dll/module? Double check the crash error dialog

Thanks for the site, I already know how to read the crash logs using Map file. anyway I suspected that error occur in one of the DLL that I've used. Maybe I will just create a released exe file with debug information.

Thanks for your help again,

You need a stack dump. You probably called a function in a DLL with bad parameters. By the way, you don’t need to use MAP files to debug release builds, and in fact should not. Simple make your release builds with debug information and debug as normal.

VS2005 - MFC - add OnInitDialog

6-Feb-07 18:01

Yha! Maybe your right, I will create a new release exe file with debug information and I will deploy it again. just incase that the problem occur again I will easily debug and saw it in the call stack using the crash address

Thanks again Steve,

Till next time

I feel dumb for asking this - but:

In VS2005 in an MFC project, how do I add an WM_INITDIALOG - Handler to a dialog?

"Events" only list child controls, and "Messages" does not include WM_INITDIALOG (only gems such as WM_INITMENU and WM_INITMENUPOPUP). I can't find anything either in solution explorer or the dialog editor.

Confused | :confused:

I'm on 2003, but it's in the overrides (OnInitDialog()), not in the messages. MFC makes the
virtual call always so there's no need to handle the message directly Smile | :)

Ah thanks!
I wasn't aware that some message get their own vitual function.

My recent 5-part article describes how. Go here and go about 3/4's down the page to find it.

You are not very encouraging Wink | ;)

In my hunt I came across the "Add function" wizard - OMG | :OMG:

this is just the most terribly overcoded underengineered dialog just after the function wizard you get from a n00b. My eyes hurt.

What about Variable Adding Dialog Box.. while adding Cntl variable for each control on Dialog Box... it really big pain.. as you have to open it again and again

Hy, since I'm new to MFC/C++ programming, I could really appreciate some help.
So can someone please explain to me what function should I use if I wanted to change the color of the dynamic (input) text that user enters? Confused | :confused:

The user should be able to select the color he wants.
Thanks Smile | :)

You can add a WM_CTLCOLOR handler to your window/dialog class and in your handler method, use
SetTextColor() to set the color for edit control(s). The background color can also be set.
Something like this:

//CMyWnd is the window class of the window containing edit control child windows
 
HBRUSH CMyWnd::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
   HBRUSH hbr = CWnd::OnCtlColor(pDC, pWnd, nCtlColor);
 
   if (nCtlColor == CTLCOLOR_EDIT)
   {
      // Set text color to bright green
      pDC->SetTextColor(RGB(0x00,0xFF,0x00));
   }
 
   return hbr;
}

To let the user pick a color you could use the color-picker common dialog (the MFC CColorDialog
class wraps it). Store the COLORREF picked by the user and use it in place of the
"RGB(0x00,0xFF,0x00)" in the code above.

handles and stack monitor help pls

van-ux6-Feb-07 11:32

can someone help in some way i could monitor un EXE stack and read the respective handles like in real time to try to find out what is going on in the stack and what is happening in the handle system...

its a uni work to detect if un exe was changed or not, i detected a strange handle that apears with diferent names but some information is the same, but the memory where the handle is located it changes each time i run the 2nd prog that changes the 1st prog..

someone could help me with a doc to write a smal thing in c++ to read in real time in way to monitor a exe stack and handles..

someone could help what means size of a handle: 0x0001e000 (???) in size this is what ?

van-ux7-Feb-07 2:28

no one ???

Frown | :(

Mark Salsbery7-Feb-07 5:27

I'm not sure what you want to look at on the stack. automatic variables? Return pointers?
That's all that's there that is useful info. If you use the disassembly window while debugging
you can see how compiled code is manipulating the stack. My assembly skills are too rusty to
provide any sample code Smile | :)

What kind of handles are you referring to? Operating system handles like HWND, HANDLE, etc.?
OS handles in Windows are opaque - they have no meaning to the user except that they represent
some object in the system. You can't, as a programmer, make any assumptions about the type
or contents of a handle. A handle could be a simple value, a structure, a pointer to a structure,
an index, etc.

You asked about the size of a handle. What do you need to know? The size of a HANDLE object?

thanks for your reply..

what i mean to read in the handle, is sections is the most important, and then mutant, file and events..

about the stack, i need to know the stack information about a thread thats is running with the EXE. for example a thread stack:

ntkrnlpa.exe!KiUnexpectedInterrupt+0xf0
win32k.sys+0x2fa0
win32k.sys+0x37a6
win32k.sys+0x37c3
ntdll.dll!KiFastSystemCallRet
firefox.exe!JVM_GetJSSecurityContext+0x2d9e6
firefox.exe+0x1012
kernel32.dll!RegisterWaitForInputIdle+0x49

i need to monitor the stack of this thread in way to monitor...

when i mean about the size of 0x0001e000 is that because i dont know what means all that number "0x0001e000" i dont have a clue... Frown | :(

thanks for the help would be apreciate, im looking more for a tuturial that could explain how to work with threads and handles read this kind of information from a file

I'm not sure about the stack stuff, but handles I can help with.

My previous point was that it's not for you to know. It's not documented and Microsoft can choose
to change what it represents at any time. You may find some documentation online about certain
Windows handles but it's really not useful - it can change at any time.
"0x0001e000" is probably an address...but maybe it's an index. Maybe it's bit flags.
