The breakpoint at SelectionToHRGN was never arrived at when trying to reproduce the error described - loading a file.

Yeah, that's a NULL ptr dereference. C0000005 is an access violation, meaning the code is accessing a bogus address. The line of the crash is mov eax,[eax] (dereferencing the address in eax) but eax is zero.
If you use the same input file on an ENglish system, does the code run? If so, then I'd start by contacting the library's author and seeing if he knows about the problem.

The library was written by an Italian guy actually, so it seems odd that international errors would occur. It may be one of those corruption problems where memory gets messed up and shows an error in another place downstream that is the subject of the corruption.

For your problems, MiniDumps, as described in http://www.codeproject.com/debug/postmortemdebug_standalone1.asp[^] and http://www.codeproject.com/tools/minidump.asp[^] may be excatly what you need.
They allow you to get a call stack written on the customers machine, without giving the customer a special debug-build or symbol information (he may use to reverse-engeneer your code).
The customer returns you the minidump-file, and you use your debugger to get a frozen image of the point where the crash occured, complete with callstack (but without variable values).
Maybe it helps to go this length, when you are otherwise unable to reproduce the error.

I have not tried it - my project was working with VC++ 7.0 anyway.
But I remember to have read smething about 'VC++ 7 only'. I am not sure about that, though.

Hi there...
Guess this is just my week for inane behavior.
I have implemented a tab control in a child window. It behaves as intended, I can insert tabs, select tabs, get data from them, change focus, etc, etc.
However, the string for the tab refuses to appear on the display ?? I've tried a number of different methods to put the string into the TC_ITEM struct (std::string, C string buffer, strcpy, string literal, sprintf). It all compiles and when traced with a debugger the string appears to have been copied to the TC_ITEM appropriately and when I get the tab after a user has selected it, the string is populated as I had set it. The control is just refusing to display it at run time.
a code snippet of my population method follows.
Would someone be so kind as to point out what I am doing wrong?
Thanks
Dave
--- cut & paste -----------------------------
// got a new element, populate a tab
char nodename[50];
ZeroMemory( nodename, sizeof(char) * 50 );
sprintf( nodename, "%s", r->name.c_str() );
TC_ITEM tab;
tab.dwStateMask = TCIF_TEXT | TCIF_PARAM | TCIF_IMAGE;
tab.dwState = 0;
tab.iImage = -1;
tab.pszText = (LPSTR)nodename;
tab.lParam = (LPARAM)r;
tab.cchTextMax = 25;
index = list.size();
// insert the tab into the display
if( TabCtrl_InsertItem( hTab, index, &tab ) > -1 )
{
// focus on tab
TabCtrl_SetCurSel( hTab, index );
TabCtrl_SetCurFocus( hTab, index );
// store the tab
list.push_back( tab );
}
else
{
MessageBox( NULL, "An unexpected error has occured while inserting tab!", "Tab Cntrl Error", MB_ICONERROR|MB_OK );
LOG->Write( "recview.h", sal::Log::error, "In UpdateTabs(): failed to insert new tab" );
}

Perhaps tab's lpReserved1 and lpReserved2 members contain random values? (They must be zero.) Try ZeroMemory()'ing tab before using it.

I see four problems there.
1. You're not zero-initializing the TCITEM struct. Always do this.
TCITEM tab = {0};2. The TCIF_* flags go in the mask member, not dwStateMask.
3. The cchTextMax member is set to 25, not the actual length of the string. cchTextMax is actually not used when you're setting the text, since the control assumes the string is zero-terminated, but the fact that you're setting it wrong makes me think you'll have problems elsewhere when cchTextMax is used.
4. You're storing a TCITEM struct in a list, but the TCITEM contains a pointer to a char array on the stack. As soon as that array goes out of scope, the pointer becomes invalid.

Thanks for the replies!
As it turned out, you were on the money with the mask member. This is my first forary into tab controls, and obviously misread the MSDN docs.

Sorry for the confusion, I should have explained the snippet more clearly to avoid leading people down the wrong track. "list" is actually a ref to a vector passed in to the function.
so, in following everyones advice, I changed the struct definition to:
TC_ITEM tab = {0};
tab.mask = TCIF_TEXT | TCIF_PARAM | TCIF_IMAGE;
tab.dwState = 0;
tab.iImage = -1;
tab.pszText = (LPSTR)r->name.c_str();
tab.lParam = (LPARAM)r;
tab.cchTextMax = r->name.size() + 1;
this solved the display poblem, so my control is fully operational now.
Thanks for all the help, this board has been great!

Glad you got it working  But you missed my point about keeping TCITEM structs in a list (or vector, doesn't matter). TCITEM::pszText is a pointer to a char array, and you're storing the pointer without storing what it points to as well. Later on if you try to read/write to a pszText pointer, it will be pointing into freed memory or other data, not the original string.

I have a library consisting of lots of files. I have one single #include file which includes all the relevant header files, depending on the compile platform. However, I would like to shove all the classes that are declared in the library into one namespace, but don't want to have to go through every #include file and put namespace blah {} around the classes and then have to put blah:: in front of every blinking function. Is there a way of grouping a collection of classes and uploading them into a namespace?
|
|
|
|
|
Add a namespace around the includes:
namespace LibraryStuff
{
#include <libheader1.h>
#include <libheader2.h>
...
}You'd only do this in the code that's using the library, the library itself would remain unchanged.

So what is it that you are having troubles with? Perhaps a code snippet of what you are doing, and the results it is producing, is in order.

Dear members of CodeProject,
I want to invite the most experienced coders (C#, VC++, VB, VB.NET, ASP, ASP.NET and all the other technologies) to join the new outsourcing auction site. There is over 5 the most famous sites on the web now (like RentACoder.com, Elance.com, GetAFreelancer.com and other) but our site is absolutely outstanding because it have now and will have in future a lot of functions and features.
Now under the launch of our site we are looking for skilled, experienced and honest developers to join us. You will work directly with customers, NO agencies, NO third party providers. We need teams of developers or very experienced individuals with perfect English (and maybe German) skills.
If you are INDIVIDUAL you MUST have at least 2 years in outsourcing like freelancer (development, working with customers directly, knowledge about full cycle of development, keep in mind deadlines, etc.).
If you are TEAM or COMPANY you must have at least 3 years of experience and 5-15 developers (or designers, or other personal depending on skills) inside of your group.
All the questions and suggestions you may send at rec@modelstyle.com,
Good luck!

Can anybody pls tell me what is back pointers
and when are they used?
|
|
|
|
|
back pointers are used to reference the owner of an object.
lets say you have an object that contains related objects ( for example, a car contains wheels ); the car class knows that it holds X number of wheels; but by default, the wheels don't know they are contained by the car; they could be contained by a bus or a truck; by adding a back pointer to the wheel class, you can know that the class that contain the wheel is indeed a car or a bus or a truck.
/// really pseudo code ...
class wheel;
class car : public vehicule
{
wheel* m_pWheel1;
wheel* m_pWheel2;
wheel* m_pWheel3;
wheel* m_pWheel4;
};
class wheel
{
wheel ( vehicule* pVehicule ){m_pVehicule=pVehicule};
vehicule* m_pVehicule;
};
...
car::car()
{
m_pWheel1 = new wheel( this; );
m_pWheel2 = new wheel( this; );
m_pWheel3 = new wheel( this; );
m_pWheel4 = new wheel( this; );
}

Hey all,
I'm trying to figure out how to directly write to a device in Windows. Basically, what I'm wanting to do is create an image of a device (specifically, a CompactFlash card that doesn't use a filesystem Windows recognises), store it as a file, modify it and dump it back to the card.
Currently, in version 0.001 of my program, I'm just calling dd for Windows using ShellExecute - this works perfectly, but obviously this isn't exactly acceptable for the final product! (and in the kludgy way I've done it, it locks the whole program and I can't implement a progress bar etc etc)
I'm HOPING it's as easy as using fopen and just treating it like a file from then on (sorry, that's my Unix background speaking)...
Any help would be much appreciated.
