(1) What character set do you display with? UNICODE? MBCS? etc...
(2) What language packs do you have installed on your computer?
(3) What operating system?

I guess!

The problem is that my contact in Israel, whom have the Hebrew package installed, told me that all the strings in my app were ???????. Should have mentionned that earlier Sigh | :sigh:

One thing that I should mention is that the string table language's is Hebrew but the dialogs are in english. Perhaps the problem lays there?

Does your friend's default locale is hebrew and what locale do you use in your program, default ?
Note : it seems better to use STL's locale class to set the locale, rather then win api directly, this all locales are set the same, win32 and c runtime.
I would recommend to switch to Unicode, it is so much easier to deal with, especially when you mix two or more langauges, the effort might well worth it. Also, try to install hebrew support on your machine (On my w2k it's in Control Panel\Regional Options\General tab, check hebrew, don't have xp machine nearby, but beleive it's in the same place). And of course the font you using must have hebrew charset.

Here's what I did so far :

in the .rc files :

#if !defined(AFX_RESOURCE_DLL) || defined(AFX_TARG_HEB)
LANGUAGE LANG_HEBREW, SUBLANG_DEFAULT
#pragma code_page(1255)
...
...
...

I did change every dialog's language to Arial so it can show Hebrew

FONT 8, "Arial", 400, 0, 0xB1

Heck, the editor won't even open the .rc file anymore because it says it's in Hebrew... so I guess the .rc files are fine!

Every place that I could find English as the language I would set it to Hebrew.

Now, in the Outlook toolbar and in the system menu's, the strings are showing correctly (I have Office 2003 and I added Hebrew) but all my dialogs are showing ?????????. I haven't been able to set Hebrew as a language for Windows XP. I'm using LoadString, is there something particular to do?

It's not showing correctly on my computer but I'll check with my contact in Israel...

I looked at the page you've sent. Does "arial" on your system has hebrew charset ? Since the menus are shown corretcly you can try to change "arial" to "MS Shell Dlg" (it's probably mapped to "Microsoft Sans Serif" whatever it is it has hebrew char). Since the title and labels appear to be RTL I assume you have set code page to hebrew.

LoadString loads the string for your current thread locale (same applies to DialogBox, FindResource etc.), this way you can have resources for multiple languages in your resource file and those functions will try to find the closest match for the current thread's locale.

Outlook Programming - User-Defined Fields

11-Feb-04 13:05

Ok, so far I've been 30% successful : the toolbars are showing correctly and some controls in my dialogs are fine as well (see link for screenshot). I was also able to display Hebrew correctly on Win XP and in Visual Studio.

Why are there some controls that won't display correctly?

Thanks!

Hi,
now it´s time for me to create user-defined fields in an outlook form.
The Problem:
How can I access those fields in my code ?
I´m using C++ and outlook´s type libary(create wrapper classes)

For example:
If I want to access the full name of an ContactItem I can use.

_ContactItem c_item(...
CString full_name = c_item.GetFullName();

But how is it with custom fields ?

Thanks a lot for helping me - Chris

Why would my CDBConnection->m_pErrorInfo be NULL after I have purposely entered an incorrect password?

Thanks,

Flickering at resizing on MFC app

Hi all,

I have written an MFC application with standard controls. But I realized that at resizing the window, the whole window flicker.

I saw that there are a lot of posting on flicker-free app in here already. But since I am not writing any fancy graphics object, I am thinking if there is a way of doing double buffering (one way of removing flickering) without having to manipulate deeply on the OnDraw() function.

I tried the Keith Rule's CMemDC object in my own derived view and override the OnDraw () to be

{
CRect bounds;
CRect lBounds;
GetClientRect(&bounds);
lBounds = bounds;

CMemDC pDC(dc, &lBounds);
CFormView::OnDraw(pDC); //CFormView is my parent
}

But on resizing, the app still flicker.

Any suggestion?

Thanks a lot,

Jimmy Chu

You can reduce the amount of flickering by handling the WM_ERASEBKGND message. I usually do it like this:

BOOL CCommunicationView::OnEraseBkgnd(CDC* pDC) 
{
	static int dont_erase_indexes[] =
	{
// list your control ID's here
		IDC_DPAS_LAMP,
		IDC_INSTRUMENT_TYPE,
		IDC_LABEL1,
		IDC_LABEL2,
		IDC_DESTINATION,
		IDC_CURRENT_STATUS,
		IDC_LOG,
		IDC_GRAPH,
		IDC_DOWNLOAD_STATUS,
		IDC_DOWNLOAD_PROGRESS,
		ID_AUTO_LOAD,
		IDC_UPLOAD_ASSAYS,
		IDC_AUTO_UPLOAD,
		IDC_BROWSE_FOR_FOLDER,
		IDC_AUTOREFINE_GRAPH,
		IDC_DIRECT_CONTROL_STATUS,
		IDC_ABORT_ASSAY
	};
	CRect	clip;
	pDC->SaveDC();
	for (int i = 0; i < sizeof(dont_erase_indexes) / sizeof(int); i++)
	{
		CWnd *pWnd = GetDlgItem(dont_erase_indexes[i]);
		if (pWnd && pWnd->IsWindowVisible())
		{
			pWnd->GetWindowRect(&clip);		// get rect of the control
			ScreenToClient(&clip);
			pDC->ExcludeClipRect(&clip);
		}
	}
	pDC->GetClipBox(&clip);
    pDC->FillSolidRect(clip, GetSysColor(COLOR_BTNFACE));
	pDC->RestoreDC(-1);
	return FALSE;
}

is it possible to make a complete windows program in visual basic c++ i have only just started learning this and was wondering just what you can do with it also does ne one know of any sites that can give me lots of info to help me plz cheers, or would borland be better

It is possible to make programs with both Visual Basic and Visual C++. The C++ version is harder to learn, but gives much greater degree of control over the applications you create and over your system.

VB, on the other hand, is much quicker to learn, but when you need to do something more difficult like customize a Windows control, it starts to run out of options.

For a good book, try to find a one with 'Learn yourself Visual C++ in xx days'. They are easy to understand, quick and effective. However, if you have no prior experience in C/C++, I suggest getting a decent book from this area first and reading it. Understanding and mastering C/C++ is the key in being a succesfull programmer for Visual C++.

It is quite possible to build complete Windows applications using either tool, Visual Basic or Visual C++. That's what they were designed to do. VC++ is harder to learn, but it also offers far more control over the target platform. VB is simple to learn, but it hides much of the detail from you and makes it simple to fall into sloppy coding habits. Borland has made excellent products in the past, but I haven't used any of them in 10 years or so. Which product you use is a matter of personal taste, but I suspect that you'll have fewer hassles using products made for Windows programming by the folks who make Windows.

As for sites that offer assistance and code samples, you can't do better than this one. Pick a language and start reading through the articles under that heading. You would also be well advised to pick up a couple of books on the language you choose to learn. Microsoft documentation is adequate for reference and quite complete, but it's useless and overwhelming for learning.
