There won't be any. From MSDN:

If the user clicks OK in the dialog box, the requested network connection will have been made when the WNetConnectionDialog() function returns.

Is there some way to retrieve this info from the system itself then ? Confused | :confused:

Try:

CONNECTDLGSTRUCT cds = {0};
NETRESOURCE      nr  = {0};

nr.dwType = RESOURCETYPE_DISK;

cds.cbStructure = sizeof(cds);
cds.hwndOwner   = GetSafeHwnd();
cds.lpConnRes   = &nr;

WNetConnectionDialog1(&cds);
TRACE(_T("dwDevNum = %lu\n"), cds.dwDevNum);

I want to show CToolTipCtrl object when user enters invalid character. Actually i want to use that class when i want. But i cant find a solution. Is there anyway to override that functionality.

I use several methods, but cant do what i want.

I use ShowWindow like funtctions, but they just show and disappear. They dont even there for a few miliseconds Smile | :)

Being mortal is what makes impossible possible.

i)declare CToolTipCtrl in ur class
like CToolTipCtrl m_ToolTipCtrl ;
ii) add the following code in constructor
TOOLINFO ti;
DWORD dwStyle = TTS_BALLOON;

m_ToolTipCtrl .Create(this, dwStyle);
m_ToolTipCtrl .FillInToolInfo(ti, this, 0);
ti.uFlags |= (TTF_TRACK |TTF_ABSOLUTE );
ti.lpszText = (LPTSTR)_T("Enter Valid Phone number");

m_ToolTipCtrl .SendMessage (TTM_ADDTOOL, 0,reinterpret_cast<lparam> (&ti));

iii) add the following code, where u want to show the tooltip

LPTSTR lpszMessage = _T("Enter Tooltip text here");
m_ToolTipCtrl.Activate(TRUE) ;
CToolInfo ti;
m_ToolTipCtrl.GetToolInfo(ti, this, 0);
ti.lpszText = lpszMessage;
m_ToolTipCtrl .SetToolInfo(&ti);

m_ToolTipCtrl .SendMessage (TTM_TRACKPOSITION, 0, MAKELPARAM(rect.right - 20, rect.CenterPoint().y));
m_ToolTipCtrl .SendMessage (TTM_TRACKACTIVATE, TRUE,reinterpret_cast<lparam>(&ti));

this code i got from some post

Your code works very good.

Using Context Free Grammers

hi Suppose I want an application which takes a source file and outputs its data members and functions.
Supposed to develop into a kind of class view explorer.
Regarding parsing the source file ....
should i go for using regular expressions rules for this parsing or
should i go for a language representation in context free grammer[CFG] and use the CFG rules for parsing

or is there any other possible ideas for source file parsing

awaiting advice

For something with fixed syntax rules such as a programming language, I would go for a CFG, since parsing it with pure regex can be relatively complicated.

Search Code Project for context free grammar to get more information.

Hope this helps.

I think that you should use a CF Grammer for parsing the file. The advantage of the CFG is, that when you have your grammer and rules, you can easely deduce code from it by yourself or a tool.

An other advantage of a CFG over RegEx is that with a CFG, you almost always have a good overview of what you are doing and where you are doing it, RegEx tend to get complicated really fast.

A recursive parser (from a CFG) is also easier to debug, than a state based RegEx parser, since you always have stack traces and you exacty know where you are and how you came there.

IMHO I think that regular expressions are great for validating strings (like postal codes, phone numbers, etc..), but for the real parsing you shouls stick with grammers and parsers.

Probably CFG.
If you want to try regular expressions, then go download and install Regex++. It has some example programs like taking C++ file and (thru callbacks) outputs an html file.

Is there anyway of looking at the code that initialises a DLL

Hey Guys,

My name is Danny Nowlan and I'm currently working on an app using Visual C++ 6, that loads an SDI application using a DLL.

I'm having an intermittant problem in release mode with some WinXP machines where the DLL won't load at all in release mode. It doesn't even get to InitInstance() In the dll. In debug mode it is perfect. The bugger is it only happens on a handful of WinXP machines

Is there a way of looking at the source code that loads the dll into my application. That way I can put in some statements etc so when I compile in release I can see what is going on.

Thanks guys

Danny

If that can help you, you could turn debugging on even for your release version (and get something between release and debug which could help you debug the release Roll eyes | :rolleyes:

)

Check following articles:

Debugging the release mode[^]

Hope this helps

The first article really helped. It discussed compiler optimisations, and the moment I turned it off it worked like a charm.

Thank you so much.

How to create disk image?

Hi,

I want to copy the entire content of a hard disk to another one. The second hard disk should be an exact image of the original one, after the copying process.

How to do this using VC++ or C++ or C?

Please suggest me the way of approach that I have to adopt.

Hoping to get a reply soon.
TIA.

regards,
Jahfer V P.

Unless you are looking for something difficult to do, I would spend $20 on a copy of Ghost. It's well worth it.

Is this only for one pc or many? Is this for a client? Are the disks the same size? I ask these questions because linux has a very easy utility to do this. The command is dd. I recently found this when partition magic failed to copy a failing hard drive because it han not been unmounted cleanly. Of course it was unmounted cleanly XP locked up when the disk stoped spinning. Good thing after a reboot it started spinning again... I booted off a gentoo linux live cd and at the prompt I typed dd if=/dev/hda of=/dev/hdb bs=8M and in about 1 hour I had a copy of a 40 MB drive on an 80 MB drive. It did not resize the partitions though but after removing the smaller bad disk windows XP booted and ran fine.

I do this all the time. I guess it shows my age... I actually had both drive sizes on my main computer sometime in the mid to late 80s. I remember that the 80MB drive cost almost $800 and that was for a drive that had hard errors on it. Since dos 3 did not support partitions above 32 MB I remember I had to split it into multiple partitions...
