SetWindowPos() and MoveWindow() are but two ways.

Does anybody know where one can get the file formats for the tables created by database engines such as ISAM, etc.

Basic Parsing support

Hi,
I'm looking for (free) helper classes to support parsing strings etc. into tokens. It's nothing to complex, basically a list of name=value; %comment , but values can stretch over multiple lines, I need to switch between different separator token sets, and things like "comment token inside string", i.e.
s = "A double slash like this: // indicates a comment"; // double-slash for comment

Any ideas?

[edit] something CString-compatible would fit in perfectly..[/edit]

I was going to tell you to RTFsite, as there are quite a few parsers in the "General C++/MFC"[^]
section. Then I realised you aren't a newbie, so I'll be a little more polite...

I've had a quick look see there, and you should still be able to find something useful!

Create Multiple Windows

I've got an application, that I'd like to convert to C++ as a learning exercise.

I've got 1 dialogbox template that I'd like to use 8 times at once on the screen.

1 want 1 main windows, and to (I guess) attach these 8 windows (with a thread to control each one) to the main window.

Where can I find an example of doing this Create Main and attach stuff.

Thanks

With or without MFC ?
If MFC, the main window should be SDI or a dialog ?

I don't really mind. I'd prefer straight Win32code, but really it is for learning, so MFC would also be fine.

I just would like to see an example of how to do it.

in MFC Version

Create your main and template resources. Create a class for each of them, CMainDlg and CTemplateDlg.
In InitInstance(), launch your maindlg with a

CMainDlg dlg;
dlg.DoModal();

In the CMainDlg::OnInitDialog()
Create your dlgs like this :

CTemplateDlg dlg1;
dlg1.Create(...); // You can customize it (Name, size, ... after creating it, sinceit will show only after the <code>OnInitDialog</code> returns.)

do this for each dlg to set their special features. If they are all identical, you can create a table of 8 CDTemplateDlg and loop on them to launch them one after another.

Would be the same if the main dialog was from a doc/view architecture (SDI may be better in this case). In the CMainFrame::PreCreateWindow function, launch the 8 dialogs as explained.

In Win32, it is a little bit more complicated to get this, but it is nearly the same, except you will have to catch the Winodws messages by yourself.

I get what your saying, I just can't fill in the blanks.

Are there any full example projects that do this?

I want to load the icon resource form an application.

What I know by now is that I will use LoadIcon function

HICON LoadIcon(HINSTANCE hInstance, LPCTSTR lpIconName);

how to get hInstance from an application (for example for WORD 2000)?

Please help

Actually, you might be better off using ExtractIcon()

For an MFC application....

// #define ICON_INDEX and APPLICATION_FILENAME<br />
<br />
int nIconIndex = ICON_INDEX;<br />
CString strExeFilename = APPLICATION_FILENAME;<br />
<br />
HICON hIcon = ::ExtractIcon(AfxGetInstanceHandle(), strExeFilename, nIconIndex);

Edited to add : Check out ExtractIconEx() too - this allows you to obtain small and large icons.

I was about to give the same answer as you, but somwthing told me that the guy who has asked it was not programming using MFC. Then I looked for how to get the hInstance from another application that the own (which is needed with ::LoadIcon()), and ... I did not find how to do it. Do you know how to do this ? I mean, retrieveing the hInstance of another running instance (with or without MFC) ?

I have never extracted an icon from an application because I never had to do it but I do know that ExtractIcon works for API as well. I also remember that if I wanted to get get the module of an application using API I would call HMODULE GetModuleHandle( LPCTSTR pModuleName )
where pModuleName would be the name of a dll or exe. If you use null then you get the current module. This is what I remember doing two years ago, because after that I started working on Unix machines and I kind of forgot most of the API that I knew. I didn't know much anyways.

There could be a function that does this for you - have a browse through the shell functions and interfaces to see if anything pops out. However, you could use this method....

Say for example, you are representing an MS Word document, myfile.doc

If you look up ".doc" in the registry under HKEY_CLASSES_ROOT, you will find the default value is something like "Word.Document.8" - it is on my machine, this may well vary depending on the version of MS Word you have installed.

If you then find "Word.Document.8" under HKEY_CLASSES_ROOT, you will find it has a number of subkeys. Navigate through these subkeys to find the default value for the entry shell/Open/command. (in this case, the full registry path is HKEY_CLASSES_ROOT/Word.Document.8/shell/Open/command)

This contains the name of the executable, which you can then interrogate for the icon!

Hope this helps!
