I'll be moving over to VC++.NET IDE when I have finished my current projects. The reasons to move. Well, mainly because VC6 won't be getting updated. Some of the new ATL Server stuff looks like it might be useful. New MSDN will only integrate into the new IDE.
I'm not 100% convinced about the new IDE yet but I know I'm going to have to learn it sooner or later.
I won't be developing many apps for the .NET framework in C++ as my customers aren't asking for it yet.
If you are still developing C++ apps for Windows then there is no rush to move over to .NET IDE.

Using VC6 SP5 ...
I'm trying to hook the CFileDialog with the following :
...
CFileDialog dlg(FALSE);
CHAR fileBuf[256] = { "output.ext"};
dlg.m_ofn.nMaxFile = 256;
dlg.m_ofn.lpstrFile = fileBuf;
dlg.m_ofn.lpstrDefExt = "ext";
dlg.m_ofn.Flags = OFN_EXPLORER|OFN_ENABLEHOOK;
dlg.m_ofn.lpfnHook = (LPOFNHOOKPROC)OFNHookProc;
...
and I'm getting an ASSERT in DLGFILE.cpp (mfc sources )
...
if (nResult)
ASSERT(pThreadState->m_pAlternateWndInit == NULL);
...
The Callback is
UINT_PTR CALLBACK OFNHookProc(HWND hdlg,
UINT uiMsg,
WPARAM wParam,
LPARAM lParam
)
{
if ( uiMsg == WM_NOTIFY )
{
NMHDR *phdr = (NMHDR *)lParam;
switch (phdr->code)
{
case CDN_FILEOK:
{
TCHAR filename[255];
DWORD dwResult = SendMessage( (HWND) GetParent(hdlg),
CDM_GETSPEC,
(WPARAM) 255,
(LPARAM) filename );
std::wstring s(filename);
if ( !ValidateFileName(s) )
{
AfxMessageBox(L"Invalid file name");
::SetWindowLong( hdlg, DWL_MSGRESULT, 1 );
return 1;
}
}
}
}
return 0;
}
Anything that I missed ? seems that all the flag are ok?
The question is that when I type "<" in the filename text field, I don't get the WM_NOTIFY in the callback, and Windows pops a standard dialog saying that what I typed is invalid, but when I type ">" I do get the WM_NOTIFY and goes into my code ??! and both caracters are invalide filename caracters?!!? Any clue on that ?
Thanks for any info.
Max.

Can't you just override CFileDialog::OnFileNameOK? MFC does hooking for you - you don't need to play low-level.

help with downloading from a login/pass web using php
hi, i would like to do something like that:
the website targeted use PHP to login with a username and a password.
and then, some menu is shown, (all using .php or .php3 extension for viewing pages.)
the fact is, if i do not log with my user/password within internet explorer, i can't even retrieve files i want using internet explorer.
but, even after logging in, and when i am able to download any file ending with .php3?someparam=somevalue&another=anothervalue etc...
when i use a offlinebrowser application to save all pages i want, the external application finally download a page which says i'm not logged on. although i can still download that page opening an internet explorer windows... (and setting the offline browser 'spider' to identify itself as IE doesn't solve the problem.)
so i have figured out that i need something, which will log in using a specified username/password, and then, will download all files linked from a single url. (and that need to work with either .php or .php3?x=1&pass=2 files...)
how can i do that?

User identity is usually maintained across a browsing session by means of cookies kept at the client side. I gues what's happening is simply that your offline browser does not keep cookies.

My app is crashing with a First Chance exception in ExitInstance().
The bizarre part is that it crashes on a line similar to this:
CMyClass* m_pObject;
m_pObject = CMyClass::allocInstance();
if (m_pObject)
Yes, it crashes on the if statement. To add to the mystery, the assembly code looks like this:
0041B431 call dword ptr [__imp__CoUninitialize@0 (008f1db0)]
What the heck is *that* all about?
This didn't start happening until I added a DLL that uses COM to communicate wirth DirectShow. The DLL contains calls to CoInitialize and CoUninitialize.

Is it a COM object ? Maybe you've called CoUninitialise and then you're trying to access a smart pointer ?

Nope, the pointer in question is about as far from the COM stuff as it can get.

Can you put the breakpoint and check what's in m_pObject? Is it a valid pointer?

It is a valid pointer (not NULL, and not 0Xcdcdcdcd).

Well, in such case it's best to 'Rebuild All', but I'm sure you've already done this
Is this a debug version without any optimizations?

It is. All you can do now is to step into disassembly at the beginning of the function and proceed instruction by instruction

I read somewhere you shouldn't use CoInitialize with either MFC or dll's, can't remember which. Try using AfxOleInit()

I'm sure there are controls on CP for that, but basically you need to set up a timer and move the text when the timer goes off.

I want to add debug information to my release build. The obvious thing to do is enable debug info in my link. However, instead of getting just a few 100 bytes added to my DLL for the reference to the PDB, I am getting 20-30k. This is contrary to what the MS minidump article states.
So obviously I am doing something wrong. All I want to do is create a PDB file with the basic symbols contained in the DLL much like MS does with their symbol files.
Anybody have any clues?

I know what you're thinking punk, you're thinking did he spell check this document? Well, to tell you the truth I kinda forgot myself in all this excitement. But being this here's CodeProject, the most powerful forums in the world and would blow your head clean off, you've got to ask yourself one question, Do I feel lucky? Well do ya punk?

Can you have a look at your .dll with dumpbin? You'll be able to check which section actually grows.

Just FYI, "Hello World" console app on my VC6 SP5 gets from 40K to 44K after enabling debug info in release configuration.

Hi,
Here is my code:
In StdAfx.h:
struct LOCK_TABLE
{
CWinThread* CurrentThread;
int Lock;
std::vector<WAITQUEUE_STRUCT> WaitQueue;
};
extern std::vector<LOCK_TABLE> LockTable;
In StdAfx.cpp:
std::vector<LOCK_TABLE> LockTable;
In my ...Dlg.cpp
LockTable.resize(NumOfDBObject);
for (int i=0; i<NumOfDBObject; i++)
{
LockTable[i].CurrentThread = NULL;
LockTable[i].Lock = 0;
LockTable[i].WaitQueue.resize(1);
}
Why I get this error message??????
"error C2039: 'Lock' : is not a member of 'LOCK_TABLE'"
What happened???????????????????????????????????

Try Project -> Rebuild all. It's kind of magical sometimes.
