Thanks CPallini,
I have tried even if we override foo and goo in class Zoo, in vtable of class Zoo, there is still no entries for foo/goo.

Hi all,
I am building my application for windows VISTA using vc++ in which I need to execute it after restarting the machine.
At one point during my application is running I need to restart the system once and then again my application should run itself.
On the machine if Windows Defender is activated then it pops up a message for permission to run the exe. I do not need that pop up it should execute itself after restarting the machine.
Please suggest me the way to do this.
Thanks

You need to run your application by making it a service or u first schedule your application to run at startup through your windows task scheduler.
then it will work fine in vista.
Have a great Day.

Hi
just a quick question from a novice programmer.
I want a storage class that only allows one instance of each thing like
set<cstring> myList;
but I want the items to be kept in sequential order
For example
I want to add "John" to the set.
Then I want to add "Peter".
Then "Chris".
Then I try and add "Peter" again it won't do it, so my set is still [John, Peter, Chris]
and then it keeps them in the order I entered them
so when I can ask for the second item I added I get "Peter.
My understanding of set<cstring> is when I insert a new member it will put it it alphabetical order.
any ideas??

yeah, easy.
Make a linked list, then upon adding a new item it gets added as a new node on the tail end of the list.
A little something like this, though with UNICODE & c++ support. There's linked lists in the stl now, but linked lists are a good educational tool, imho - hence my recommendation to write some code that uses your own implementation of them at least once.
struct myListItem
{
char *itemText;
int origPos;
myListItem *nextItem;
myListItem *prevItem;
};
myListItem *add(myListItem *linkedListHead, char *newText)
{
myListItem *curItem;
bool alreadyExists = false;
int curItemNum = 0;
curItem = linkedListHead;
if (curItem != NULL)
do
{
if (!strcmp(curItem->itemText, newText))
return curItem;
curItem = curItem->nextItem;
curItemNum++;
}while (curItem->nextItem != NULL);
else return NULL;
curItem->nextItem = (myListItem*) malloc(1*sizeof(myListItem));
curItem->nextItem->prevItem = curItem;
curItem->origPos = curItemNum;
curItem = curItem->nextItem;
curItem->itemText = (char*) malloc(strlen(newText)+1);
strcpy(curItem->itemText, newText);
return curItem;
}

All,
My environment is Windows XP 64 bit and am running 32 bit applications. When trying to attach memory validator to a running process, its not allowing me to do so. It shows a dialog box with "dll injection failed".
Any clue to resolve this would be of great help. Mem validator has helped us a great deal in the WinXP 32 bit world. But am not able to make it work in the 64 bit world.
Please let me know what am I missing?
Thanks
Rajdeep

I am working on a library that will process large (>4GB) files and I need to be able to randomly access the data.
STL's seekg() only appears to use int s which limits me to 2GB.
Any suggestions?
THanks.

Per Microsoft, any file greater than 2GB can not be read using the fstream class. This is a limitation in the stream I/O functions. For Win32, check out SetFilePointer() . Otherwise, you could use the lowest I/O in the CRT: open/_read/_write/_lseek/_lseeki64.

Thanks, SetFilePointer() looks the best option.

My MFC SDI application lists the recently used files under File/Recent menu. Where does it get this information? Has my program registered itself in the registry? I don't have an installation feature with my app. Or is it getting this info from some operating system feature?

By calling LoadStdProfileSettings() .

Thank you! I was wondering, is there an easy way to have my app store it's current window size and screen position into the registry on close? (MFC SDI). Thanks again

You can insert your data to registry see here[^].

Yes, use SetWindowPlacement() and GetWindowPlacement() in the frame's ActivateFrame() and DestroyWindow() methods.

First of all i would like to say am very new to C++ and am probably asking somethingthing very simple. i am trying to write a win32 console application that moves files from one folder to another on the same drive.
when i call the win32api's MoveFile function it fails with the following error "The filename, directory name, or volume label syntax is incorrect". below is the offending piece of code.
i have checked the file exists and the destination folder also exists.
void BackupFile(string* origpath,string* filename,string* unitid,string* owner,string*month)
{
WIN32_FIND_DATA win32_find_data;
HANDLE handle;
string dest;
dest = "C:\\data_2008\\" + *owner + "\\" + *unitid + "\\"+ *month;
handle = FindFirstFile((dest+"\\*.*").c_str(),&win32_find_data);
if(handle != INVALID_HANDLE_VALUE)
{
dest += "\\" + *filename;
if(!(MoveFile(origpath->c_str(),dest.c_str())))
{
DeleteFile(origpath->c_str());
}
}
}
any help will be highly appreciated

Have you consulted a debugger?
|
|
|
|
|

i should have mentioned that when i check the values in the debugger the values are correct and are pointing to the correct paths.
i have managed to narrow down further and the problem seems to be the dest.c_str() while trying to move the file.
if i substitute it with the actual value it seems to work fine.
i have also tried replacing the datatype to LPCTSTR and below are the result
LPCTSTR sourcePath = "C:\\somefolder\\file.ext";
LPCTSTR destPath = "C:\\folder2\\file.ext";
LPCTSTR sourcePath = origpath->c_str();
LPCTSTR destPath = "C:\\folder2\\file.ext";
LPCTSTR sourcePath = origpath->c_str();
LPCTSTR destPath = dest.c_str();
i get the same when i change the datatype to a CString
any help will be highly appreciated

What are you doing with sourcePath and destPath ? Make sure that dest and origpath are still in scope, because otherwise the objects will be destroyed and sourcepath and destPath will point to memory which has been deleted. Make sure also that you don't modify the string objects in between. The two LPCTSTR point to an internal buffer of the string object, so if you modify the string object, this buffer can be destroyed.
