The role of TranslateMessage is to generate more "high lavel" messages from the "low level" ones that come directly from the input.
The typical case is WM_KEYDOWN/WM_KEYUP that, if observed for certain keys and shifts, generates WM_CHAR and WM_UNICHAR.
All new messages are re-posted on the same message queue, and hence fetched from GetMessage tehmselves.

How to convert string “ABC” to “BCD”
into UNICODE?
CString strSource;
strSource = L"ABC";
TCHAR SourceFile[100];
_tcscpy(SourceFile, strSource );
MessageBox(SourceFile); // display "ABC" - OK!
below 3 operators are unproperly !
SourceFile[0] ++;
SourceFile[1] ++;
SourceFile[2] ++;
MessageBox(SourceFile); // display ">BC"

I've tried your code in Microsoft Visual C++ 6.0 in an ANSI system and it seems to work properly. That is, it first displays "ABC" and then "BCD".

Use a thread, don't do everything on the main thread. When you do some time consuming task on the main thread the result is more like what you are facing right now.

Hi All,
I am stucked in a problem. I need to jump at a file's MFT record. Is there any way or API which can tell me the logical cluster number of a File's matadata location. I have to read the files data run which is in the MFT. FSCTL_GET_RETRIEVAL_POINTERS gives me the data run as well as the extends , but it doesnt provide the LCN of that location.
Is there any method which can provide me the LCN of a metadata file(MFT)of any particular file. 
Thanks in advance.

Is it a single line edit control?
Check if you can set the multi line property of the edit control to true and the want return property as well to true.

Hello Friends
Do u know any function which closes all open files so that i can delete that file b'coz i m using movies function and i used closeMovieFile() but still after that i m not able to delete so is there any other that closes all open files?or suggest me some other way?
Thanks
Yogesh

|
|
if it is files then u can use _fcloseall()
|
|
|
|
|
it is not file it is .avi file.
|
|
|
|
|
any file if you are using FILE pointer to open it , u can close all those files using _fcloseall() function.
|
|
|
|
|
I m not using filepointer to open it.I m using
OpenMovieFile(&FDestName, &myRefNum, fsRdWrPerm);
----
-----------
then--
CloseMovieFile(myRefNum);
but it is not deleting,is any other function in movies library?

I'm using
int res= m_cListControl.InsertItem(&lvi);
to insert item in list box, but problem is that inserted item shud be reflected after execution of above statement, but it reflects after control comes out of that function, so please give me hint or solution.
|
|
|
|
|
May be you could call RedrawItems followed by UpdateWindow as soon as you call insert and item into the list control.

I have written a couple of programs using Borland Builder C++ for the PC.
Is there a relatively pain free way to allow me to use them on the Apple Mac, or will I have to start from scratch?
It doesn't seem much to ask?
Fingers crossed!!!

if it's basic stuff (command line/console application) , it should be straight forward.
If it's UI, then you probably will have to start from scratch.
but hey, it's a good exercise.

I used the following method to cancel the serializing process:
void CMyAppDoc::Serilize(CArchive &ar)
{
if (
{
ar.abort();
return;
}
}
But it always cause an exception. Any idea?
Thank you masters!
