eg. Chinese,
I can't not input chinese when the EDIT has ES_PASSWORD style

This is not an answer to your question, but I'm just curious. Don't take it personally.
Are you setting a Chinese password? 
It must be difficult to type those characters even when you see them. How possibly can you be sure of what's being typed when all you see would be asterisks.

Usually you have to type two times the new password. For a Chinese one, you have to do it eight times.

Are you able to type in Chinese character into the control without password style at first? The app is fully Unicode?
I am able to type Chinese character into a CEdit control with and without password style. There's something else wrong I guess.

I don't know, but I pressed some random keys and this character[^] appeared. I may not be able to reproduce the thing though.
I promise never to set a Chinese password. No, really.

Hi all,
I have a project that uses unicode character set this snippet gives me an error:
CMimeMessage msg;
CoInitialize(0);
msg.SetSender(L"Administrator@redmap.com");
msg.SetSenderName(A2T("Redmap Networks"));
msg.AddRecipient(EmailAddress);
strValue = W2A(EmailAddress);
char dom[100]="";
int a = GetDomain(strValue.c_str(), dom);
if (a == 0){
strValue = dom;
msg.SetSubject(A2T("Download Notification"));
The bold part gives me errors and i found them here(atlmime.h):
inline BOOL SetSenderName(LPCTSTR szName, UINT uiCodePage = 0) throw()
{
if (szName == NULL)
return FALSE;
CHeapPtr<char> szNamePtr;
UINT nLen(0);
BOOL bRet = AtlMimeConvertString(m_spMultiLanguage, uiCodePage, szName, &szNamePtr, &nLen); if (bRet)
{
It seems that m_spMultiLanguage must be initialized, how do I do that?
I tried calling CoInitialize(0) before feeling up msg it wont work. Any advice?
Thanks,
Jayjay

I am in the process of reading the Book "Windows 95 with MFC" by Jeff Prosise. I am using the first edition of the book. I have compiled the program Paint4 which is the first example given of
the Document/View Architecture. I have copied the code directly from the CD. With two very minor
changes, the code compiles but fails to run. I am wondering, if this example is known to be bad. I looked around on the internet for a list of know errors in this book. However, I could not find such a list. I would like to get this example running, however, I am finding it hard to debug. The program bombs out inside MFC code.
Any advice?
Thanks
Bob

Does the program fail to start, or does it start and then stop before any window is drawn? How about setting a breakpoint in the app's InitInstance() to find out?

Maybe we could help with that, however you should be more detailed about the runtime error.

Thanks for the responses. Here are the details on the error: It dies with an assertion
error in the following MFC module:
void CSingleDocTemplate::SetDefaultTitle(CDocument* pDocument)
{
CString strDocName;
if (!GetDocString(strDocName, CDocTemplate::docName) ||
strDocName.IsEmpty())
{
// use generic 'untitled'
ENSURE(strDocName.LoadString(AFX_IDS_UNTITLED));
}
pDocument->SetTitle(strDocName);
}
Here is my InitInstance method.
BOOL CPaintApp::InitInstance ()
{
SetRegistryKey (TEXT("Programming Windows 95 with MFC"));
LoadStdProfileSettings ();
CSingleDocTemplate* pDocTemplate;
pDocTemplate = new CSingleDocTemplate (
IDR_MAINFRAME,
RUNTIME_CLASS (CPaintDoc),
RUNTIME_CLASS (CMainFrame),
RUNTIME_CLASS (CPaintView)
);
AddDocTemplate (pDocTemplate);
RegisterShellFileTypes (TRUE);
CCommandLineInfo cmdInfo;
ParseCommandLine (cmdInfo);
if (!ProcessShellCommand (cmdInfo))
return FALSE;
m_pMainWnd->DragAcceptFiles ();
return TRUE;
}
The code reaches the call to ProcessShellCommand. However, it dies in that call. Here is the call stack when it dies.

The path of execution, includes the following method:

{

}
While the code is dying inside an MFC module, I have to assume that it is not a bug with MFC. Since, I am doing this as a learning exercise, what is the best way for me to debug this?
Thanks

I created an environment variable using the Windows System Properties page. In my program I called getenv("varname") to retrieve the value of my environment variable.
After changing the value of my variable, I can see the change when running my program from the desktop but I get the old value when running the program from within MS Vis C++ unless I restart Vis C++. Obviously Vis C++ reads the environment settings and uses them from that point on.
Is there any way to "refresh" the environment from within Vic C++ so that the next time I run my program, it picks up the new value?
Thanks!

I don't know if there's a way to do that in Visual Studio.
This[^] may at least explain why it happens.

Looks like the only way to get the new value is to read it from the registry. Using regedit I can see the new value under key
HKEY_CURRENT_USER\\Environment\\SSSRights
which has a value of "A".
But there seems to be something wrong with my code becomes I always get a return value of 87 which apparently means ERROR_INVALID_PARAMETER when I call RegQueryValueEx(). hMyKey has a valid handle after call to RegOpenKeyEx().
Here is my code:
HKEY hMyKey;
long lResult;
LPDWORD pKeyType = REG_SZ;
LPDWORD pKeySize = 0;
char* strKeyName = "SSSRights";
char* strKeyVal = "\0";
RegOpenKeyEx(HKEY_CURRENT_USER, "Environment", 0, KEY_QUERY_VALUE, &hMyKey);
lResult = RegQueryValueEx(hMyKey, strKeyName, NULL, pKeyType, (LPBYTE)strKeyVal, pKeySize);
RegCloseKey(hMyKey);

You couldn't possibly compile that
Try
HKEY hMyKey;
if (ERROR_SUCCESS == ::RegOpenKeyEx(HKEY_CURRENT_USER, _T("Environment"), 0, KEY_QUERY_VALUE, &hMyKey))
{
DWORD KeyType;
DWORD KeySize = 0;
TCHAR strKeyName[] = _T("SSSRights");
if (ERROR_SUCCESS == ::RegQueryValueEx(hMyKey, strKeyName, NULL, &KeyType, NULL, &KeySize))
{
<code>
TCHAR *pKeyVal = new TCHAR[KeySize / sizeof (TCHAR)];
::RegQueryValueEx(hMyKey, strKeyName, NULL, &KeyType, (LPBYTE)pKeyVal, &KeySize);
delete[] pKeyVal;
}
::RegCloseKey(hMyKey);
}

Yes it compiled without any errors/problems.
I tried yours and it works but it brings up the following questions:
Why do I need the first call to RegQueryValueEx? What does it do? Why does the first call fail when I provide a buffer instead of NULL?
Thanks!

What compiler are you using?
This line alone won't compile:
LPDWORD pKeyType = REG_SZ; <-- error C2440: 'initializing' : cannot convert from 'int' to 'LPDWORD'
There's several problems
HKEY hMyKey;
long lResult;
LPDWORD pKeyType = REG_SZ; <code><-- wrong data type - should be a DWORD
It's also an OUT variable (if used correctly) so initializing it is pointless</code>
LPDWORD pKeySize = 0; <code><-- wrong data type</code>
char* strKeyName = "SSSRights";
char* strKeyVal = "\0"; <code><-- You need to actually allocate space for the returned characters
Had the query actually succeeded, it most likely would have crashed
trying to write data to a const character array of length 1.</code>
jpyp wrote: Why do I need the first call to RegQueryValueEx? What does it do?
It sets KeySize to the number of BYTES required to store the returned string.
I use that value to know how big the buffer needs to be, which I allocate on
the next line.
You could have just allocated an arbitrary number of bytes, but
you'd get a truncated string if the registry entry was longer than your buffer.
The function is capable of returning the necessary buffer size, so that's the
proper way to do it.
jpyp wrote: Why does the first call fail when I provide a buffer instead of NULL?
Your incorrect use of LPDWORD pKeySize = 0; effectively reults in passing a NULL pointer as the
lpcbData parameter in the RegQueryValueEx() call. That is not allowed - the function
needs to know how big of a buffer it has to return data in and also needs to be able
to set the actual number of bytes placed in the buffer.

I use Studio 6.0 and you are right it does not compile. I had taken out the initialization before in my code but forgot to take it out in my first post here.
I understand now why it wasn't working initially. The size of the buffer must be the same as the value in the last field. I was providing a value of 0 for KeySize because I thought it was a output value only. So only one call is necessary but it is certainly safer to do it your way to get the actual size of the value.
As for the wrong data types, I took those directly from the MSDN library help page. Their data type are LPDWORD for the key type and key size fields.
Thanks a lot for your help!
