Win32 apps can have multiple languages in a single EXE or DLL. If you look in your .RC file, most have a section like this:
#if !defined(AFX_RESOURCE_DLL) || defined(AFX_TARG_ENU)
#ifdef _WIN32
LANGUAGE LANG_ENGLISH, SUBLANG_ENGLISH_US
#pragma code_page(1252)
#endif //_WIN32
You can define similar sections for each of the languages you wish to support. When your application loads resources, Windows will choose the appropriate language section based upon the language settings for the current thread. There are also ways to define 'language-neutral' sections, for things that aren't necessarily language dependent (like icons, for example).

Thank you! This is what I wanted to know.
Is it possible to set up alternate languages through the MSVC++ editor or will I need to edit my .RC file manually?

In VC6 and VS.NET, select a resource in the Resource View. Then select Insert, and Resource Copy. You'll then be prompted for a language. This inserts a copy of an existing resource, but marked for the new language.

Thank you! That just leaves the question of how to test the internationalization once I implement it. Is there a way to trick my computer into thinking it's French?

i write a class with VC,but why so many warnings?
i doubt it's come from my virtual class.but why?
see my source code following:
virtual class:
ZDataFile.h:
class ZDataFile
{
public:
virtual void SetSpliter(string strSpliter) = 0;
virtual vector<vector<string> *> LoadData() = 0;
virtual vector<string> LoadLine(int iLinNum) = 0;
virtual vector<string> LoadColumn(int iColNum) = 0;
};
subclass:
#include "ZDataFile.h"
class ZTxtDataFile : public ZDataFile
{
public:
ZTxtDataFile(const char *FileName);
virtual ~ZTxtDataFile();
private:
string Spliter;
vector <vector<string> *> FileData;
ifstream *myfile;
};
.cpp
ZTxtDataFile::ZTxtDataFile(const char *FileName)
{
myfile = new ifstream(FileName);
if(myfile->fail())
{
throw "can not open file!";
}
}
ZTxtDataFile::~ZTxtDataFile()
{
delete myfile;
}
the warning is:
documents\vc\stabctrl_demo\test\zdatafile.h(23) : warning C4786: 'std::vector<std::vector<std::basic_string<char,std::char_traits<char>,std::allocator<char> >,std::allocator<std::basic_string<char,std::char

The compiler doesn't like some STL related stuff. Have a look at http://www.bdsoft.com/tools/stlfilt.html[^]... atleast it helps a little bit.

That "identifier too long" warning is harmless, you can turn it off with a #pragma

I'm having a really hard time getting this function to properly find a file. I know I'm supposed to use the registry for app initialization info, but I've got an old app and DLL that use an INI file and I need to continue supporting it.
I'm just trying to read from a file called "api.ini" in the same directory as the application. Of course, that directory is not known at compile time. I determine the directory using GetModuleFileName() and append api.ini to the full path. Then I convert all '\' chars to '\\' since that is how the func needs it. This never works!
If I put the api.ini file in the WINNT directory, and only pass "api.ini" as the last param to GetPrivateProfileString(), it properly finds the file. If I hard code the full path ("c:\\program files\\test\\api.ini"), the function finds the file IF the application is run from a different directory (the VS 6.0 dev environment.) However, if I place the app in the c:\program files\test\ directory, then it fails and can't find the file.
Does anybody know why this is not working for me? It seems so simple...I assume I'm missing something really easy. I should be able to just pass the full path to the file and have it read properly. By the way, I have verified that the path I pass to GetPrivateProfileString() is the correct, full path.
Any help would be greatly appreciated.

You don't need to convert \ to \\, it's only for hardcoded strings you do that.
Try ´not to, and see if it don't help...

Thanks for the suggestion, but it didn't seem to help. It's very odd, now that I'm not modifying the string at all (leaving the single slashes alone), I'm passing the same file path string to GetPrivateProfileString() that I pass to CStdioFIle::Open(). The file opens properly, but GetPrivateProfileString() can't find it (it returns the default value.)
Does anyone have any other ideas? Could it have something to do with the fact that this is MFC?
Thanks.

Have you debugged the app to see what GetModuleFileName() is returning? It should retrun a fully qualified path (i.e., the filename is included). You have to remove the filename before appending another filename.
char szBuffer[MAX_PATH] = {0};
GetModuleFileName(hInstance, szBuffer, sizeof(szBuffer));Something like the above will give you C:\My Path\myfile.exe. You'll have to drop myfile.exe before you add the other filename or else you'll get C:\My Path\myfile.exe\api.ini.
Oh, and like it was stated, you don't need to escape the backslash unless it's a string literal (i.e., you're typing it in the code directly).

I think the two suggetions mentioned will work for you. That being said, I feel it is my duty to point out one thing: GetPrivateProfileString is EVIL. If you ever run on a 9X box and your INI file gets to be bigger than 64K, it will mysteriously fail, and you will spend a lot of time tracking it down.
I'd personally recommend using an INI clas (I'm sure there's one here on CP - or you can write your own), or write some simple routines to parse a text file and get the info you need.
Yes, it IS more work to do it that way, but you have more control, and aren't subject to 64K limitations.

I have an MFC app that links several libs and DLLs. Does it matter how my libs and DLLs were built, whether it is Multithreaded or Multithreaded DLL, as long as they link? I'm just not sure whether everything is totally working yet.
If my app is compiled as "multithreaded DLL", must all my DLLs and libs be compiled the same way to work properly?
In one case, UNZDLL.dll (a dll for unzipping files) doesn't seem to work right when called from a DLL at all, however it is built (I don't know how this one was built). I'm just trying to eliminate some possibilities.
Thanks!

mixing DLL and libraries compiled with different crt implementations, produces most colorful and difficult errors to diagnose. Typical error is when you create an object in one DLL and try to destroy in the other.

Uggghhh. Thanks for the foreboding warning. I'll find "multithreaded DLL" versions of those DLLs.
One more question: Do the CRT libs only matter for DLLs and libs that use MFC? I have several DLLs and libs that are not MFC. Do I need to find new versions of those too?
Thanks again.

It applies to all executables (or almost all). The way windows API avoid the problem is they use some other mechanism to allocate memory (like HeapAlloc, CoTaskMemAlloc) and they do not use global/static variables. You can use a dll with different crt if you absolutely sure there is no memory "exchange" and no global variables (that is why MFC dlls are especially unsafe).
P.S. c++ export dll's, by definition must be used in the same CRT environment they are compiled for.

How can I know when the app gets minimized?
There is no WM_ for that, or...

Try WM_SYSCOMMAND with WPARAM SC_MINIMIZE.

Hey, how can you make dc draw commands (like FillRect) in a dialog box? The Dialog is a child of the CDialog class. Thanks
Bob

Provide a handler for the WM_PAINT message.

If you are just wanting to fill in the background, then you should handle the WM_ERASEBKGND message, as this still allows default handling of WM_PAINT, meaning that dialog controls will paint themselves properly.

Hi!,
I use ODBC in a database MFC project. In My project, I already have the CClinicView, CClinicDoc and CClinicSet that represent my clinic table. I would like to add another table into my project. How can I do this?
Thanks!
Everything's beautiful if you look at it long enough...

You mean Multiple recordsets in an app?
To get multiple recordsets, you must create the CDatabase object first. Then you can construct as many recordsets as you want, passing a CDatabase pointer as a parameter to the CRecordset constructor. You start by embedding a CDatabase object in the document in place of the CRecordset object. You also include a pointer to the primary recordset. Here are the document data members:
CClinicSet* m_pClinicSet;
CDatabase m_database;
In your overridden CDocument::OnNewDocument function, you construct the primary recordset on the heap, passing the address of the CDatabase object to the recordset constructor. Here's the code you insert:
if (m_pClinicSet == NULL) {
m_pClinicSet = new CClinicSet(&m_database);
CString strConnect = m_pClinicSet->GetDefaultConnect();
m_database.Open(NULL, FALSE, FALSE, strConnect, FALSE);
}
In the CRecordView::OnInitialUpdate add:
m_pSet = GetDocument()->m_pClinicSet;
if(m_pSet->IsOpen())
{
m_pSet->Close();
}
m_pSet->Open();
Now you create another Class derived from CRecordset and link it with the table you want. and in the View, suppose you will load a list with this table.
in this case called CSectionSet.
void CClinicView::LoadListbox()
{
CClinicDoc* pDoc = GetDocument();
CListBox* pLB = (CListBox*) GetDlgItem(IDC_SECTIONS);
CSectionSet sect(&pDoc->m_database); // db passed via constructor
sect.m_strFilter.Format(....whatever filter you want);
sect.Open();
pLB->ResetContent();
while (!sect.IsEOF()) {
////load the ListBox
}
// sect closed by CRecordset destructor
}
I hope it works for you..
