Hi everyone , I have an edit control and 2 APIs for saving text from and loading text to the edit respectively.
However, when I load text, instead of giving out the exact alphabets in the text, it gives chinese!! Please, I need help to tackle this problem,any psitive help will be greatly appreciated.
Obviously, the only solution is to learn Chinese.
or show us your code.

The code seems to have all the functionality within it for opening files. Have you tried opening a file that doesn't contain Chinese?
Just out of curiosity, I would like you to rebuild this code on your machine again with a call to GetTextMetrics().
We can then examine the last attribute of the TEXTMETRIC struct to determine the character set of the font.
if tmCharSet == 136 you are in Chinese.
I'm sorry,portis, i'm lost.
I'm sorry,portis, i'm lost.
You appear fluent in your windows programming.. I'm surprised you haven't messed around with the getting the current text attributes:
HDC hdc;
TEXTMETRIC tm;
string msg = "Current Char Set is: ";
hdc = GetDC(hwnd);
GetTextMetrics(hdc, &tm);
msg += static_cast<char>(tm.tmCharSet+'0');
MessageBox(hwnd, msg.c_str(), "Char Set:", MB_OK);As I have stated before, I am learning by myself, so It's possible that i missed that. Thank you for your compliment and contribution, portis, i really appreciate it,it has renewed my zeal to continue.
However, i still do not know how to implement GetTextMetrics() to suit my needs.
I want to change the output from Chinese to English. How do I do that?
To be honest, I'm not really sure what is going on with your machine; however, I do believe that if we can gather the current state of your font and text settings, maybe we could come up with some ideas.
I would like to determine what charset your machine is using.. maybe it would give us a little insight as to what is going on.
All I am asking is that you compile the above code either by itself or you can also add to your program at various points.
Here is another function we could consider in our efforts to get a peek inside of your machine:
GetFontLanguageInfo() Function
The GetFontLanguageInfo function returns information about the currently selected font for the specified display context. Applications typically use this information and the GetCharacterPlacement function to prepare a character string for display.
Syntax DWORD GetFontLanguageInfo( __in HDC hdc );Parameters
hdc [in]
Handle to a display device context.Return Value
The return value identifies characteristics of the currently selected font. The function returns 0 if the font is "normalized" and can be treated as a simple Latin font; it returns GCP_ERROR if an error occurs. Otherwise, the function returns a combination of the following values.
You guys should please help me, any text i open with my edit control is in Chinese,meanwhile the text is originally in English.
I need someone to really help me, i cannot continue to the next chapter of my bok until i understand the one i just finished.
Here is a whole program implementing Clinton Portis's suggestion of getting the char set out of the TEXTMETRIC struct. Just run the program and post the results here of what was on the screen. Also, it prints the output to a text file in whatever dir you run it from (Output.txt))...

OK, the code compiled and my tmCharSet ids ANSI_CHARSET.
What do I do next ,please.Thank you for your time,frederick, and I'm sorry for my mistakes.

What do I do next ,please.Thank you for your time,frederick, and I'm sorry for my mistakes.
Since you are obviously compiling with UNICODE #defined, call the ANSI-version of SetWindowText excplicitly when setting the EDIT control's text (naturally do that only when you work with ANSI text).
As of now, your app displays a UNICODE text file (almost) as expected (try saving a file as UNICODE with e.g. Notepad and load that file).
As a general rule, read the documentation about the Windows functions/other stuff really _carefully_, it will pay off sooner than later.
So the fix is the following
pszFileText[dwFileSize] = 0; // Add null terminator
if(SetWindowText[B]A[/B](hEdit, pszFileText))
bSuccess = TRUE; // It worked!PS. There are more things to fix in the code but I will not go into them now.
Sorry but I managed to leave out one thing regarding the above change.
// Since the function became an 'ANSI-version',
// use LPSTR instead of LPWSTR
LPSTR pszFileText;
// and ...
pszFileText = (LPSTR)GlobalAlloc(GPTR, dwFileSize + 1);OK,mitrmkar, the code compiled successfully but it still doesn't give me English, and please my MDI child has failed to create....please any help will be appreciated, and thank you all in advance for your time spent on my problem!

}OK,mitrmkar, the code compiled successfully but it still doesn't give me English
I suggest that
- open Notepad
- type some text and save a file as ANSI
- save it also as UNICODE
Open both the files with your app, and tell us what happens ...
FYI, for me your LoadTextFileToEdit() loads and displays ANSI text as it should.
Wow!! I saved the same text with two different names, one in ANSI and the other in Unicode.
Then, when I used my edit to open the 2 files, the ANSI file still came out Chinese, but the Unicode came out in English!!
Is that the problem? If yes, what should I do to make it keep coming out in English, maybe I should start saving my files as Unicode?
the ANSI file still came out Chinese, but the Unicode came out in English!
Now there is some kind of mismatch here, maybe you could zip the project (*.c*, *.h, *.rc) and post it here.
what should I do to make it keep coming out in English, maybe I should start saving my files as Unicode?
Probably it would be easier to stick with the ANSI and master the UNICODE later. First of all you have to understand their difference though and how that impacts your programming (that is actually one thing that you have just stumbled upon).
We already have the main source code; all that would be needed would be the h and rc file. I'd give a shot at compiling it if I had those. However, I'm wondering if some setting isn't messed up in the project file.
