Should be something like,

Function(WPARAM wp,LPARAM lp)
{
CString str;
Str.format("%s",*wp);
AfxmessageBox(str);
}

I think this was a repost.
Try changing from:
CString str1=”hai”;
To:
CString str1=_T(”hai”);

Thanks for your Reply

As Prasad suggestion it was illegal format,
str.Format("%s",*wp);
Runtime Error.

As mandanani suggestion ,Iagree
CString str1=”hai”;
To:
CString str1=_T(”hai”); its correct

But my programme was Socket Programme so I want to send the OnReceiving Character through WPARAM.
Ireceive the data in TCHAR and converted in to *CString and pass through the WPARAM

CString str1=”hai”;
CString* str2;
Str2=new CString (str1);

PostThreadMessage(WM_USER + 100,(WPARAM)_T(str2),0); /** this is wrong***/

PostThreadMessage(WM_USER + 100,(WPARAM)str2,0)

That will pass the "raw" pointer to the message handler for WM_USER+100. Be sure to delete that pointer when you are done with it.

Peace!

Didn't I answer this yesterday?

As I said then - you are allocating a string on the stack. When you leave the function, it is destroyed. Some time later, your posted message is dealt with, the wp now points to junk.

In the first case, you are posting an address of a string built into the data segment of your program, so it will still be valid later.

VC++ compilation

If I compile the code as a UNICODE built , which compilation would it be UTF-8

, UTF-16 or some other .

I mean to say what support it would be UTF-8 or UTF-16.

and If nothing what can be done to make it utf-8 if I am using wcstombs ,_wcslen functions ?

Using MultiByteToWideChar is the solution ?

Internal a LPCWSTR/CStringW is in UTF-16 LE, a CString also when you compile in UNICODE.

Converting UTF-16 LE to UTF-8 you should use WideCharToMultiByte( CP_UTF8, 0, stringw, BYTE* );

When you want a Unicode file, you should first write an encoding tag.

I'm using Visual studio 6.0 and MFC.

I add a menu resource to my application and define all required names.

Menu produces its IDs automatically (e.g. ID_HELP_ABOUT) I use class wizard to add a handler for the command message. Every things OK. But when I revisit my menu and decide to add another handler for another item, a few days later, I see all those IDs turned to numbers (e.g. 32792) I then have to find the ID and retype it to be able to use the class wizard to add a handler.

I know how to add a handler manually, but it's a pain in my ...;P

Is there any way to return all IDs back? (I hope it's not deleting .clw file, it's even more pain to reassign all those classes, etc.)

Actually in your "resources.h" you should have a relation of IDs and assigned int values. But it is the first time I hear about what you are saying. Maybe is there an option somewhere where you choose about seeing IDs in number or in name, but not sure about

At this point, what does the project's resource.h file look like?

Nothing especial, except some resources have similar IDs

Same here with VC.NET 2003:

The resources in the resource-editor and %PROJECT%.rc-file are the (correct) numbers, whereas the resource.h file has the (correct) ID-to-number table.

Annoying, but I could live with it. But as you mention it...

Failure is not an option - it's built right in.

If you use another "standard" IDs or Windows constants like windows styles (WS_MAXIMIZE) or attributes for some classes (PS_SOLID) and so on... are they ok? or have been transformed in their equivalent numbers too?

Sorry, I misunderstood what you mentioned.

Yes they are ok. I mean other resources like those I use for dialogs will be shown OK in "Resource view".

Everything OK, but menus.
