Can I use TextOut with possability to scroll window?
|
|
|
|
|
|
and if I use win32 without MFC?
|
|
|
|
|
The sample that led mike post will help you.
If you have an application without MFC, just remove the MFC objects in that sample and you will see the plain WIN32 functions for scrolling and text output.

The answer is still yes but you will have to do much more work. If that is your intention I recommend you get a good book to learn fundamentals of Win32 programming from. Trying to figure it out from forums is not going to be very productive.

why are junk char(ýýýýÝÝÝÝÝÝÝÝÝa a P ÿ) appended while writing CString to CFile
pls advice..
|
|
|
|
|
possibly specified length of buffer is more than the string length.
post writting code.
|
|
|
|
|
Pls find the code here
strLine.Format("%s %d %d %d",strAbc,dDlgResID,dwData,nCmd);
strLine.TrimRight();
strLine=strLine+"\r\n";
CFile file;
file.Open("c:\\some.txt", CFile::modeCreate|CFile::modeNoTruncate|CFile::modeReadWrite);
file.SeekToEnd();
file.Write(strLine,strLine.GetLength());
|
|
|
|
|
the first param in write() method of CFile need a pointer point to the string, but the given param is not a string , just a CString object, try LPCTSTR operation;

That happens automatically.

This line is your problem:
ptr_Electron wrote: file.Write(strLine,strLine.GetLength());
The first character (or more) of a CString is a length byte(s). You need to get only the data:
file.Write(strline.GetBuffer(strline.GetLength(), strLine.GetLength();
Hope that helps.

It is not necessary to call GetBuffer() since Write() is not modifying the string.

In this case, it is - he's using a CFile and writing a CString. Without the GetBuffer, it will write the size of the string as well as the string.

That's what the LPCTSTR operator is for.

This not necessary, inefficient and leaks memory (where is the call to ReleaseBuffer?).

There is no memory leak - nothing was allocated on the stack. As for ReleaseBuffer, it isn't needed. According to MSDN you must call ReleaseBuffer IF the data has been modified - and it hasn't.
I personally prefer the cast, but was just showing and explaining why the OP was seeing the junk.

You haven't posted enough code to be certain but GetBuffer should be matched with a call to ReleaseBuffer. Also, as another poster pointed out, since you're not modifying the string the call is not needed; use operator LPTCSTR instead.

Well, the code I posted does what the OP was looking for - there isn't more code needed. He simply was writing the string to a file.
As for release buffer, MSDN says
If you use the pointer returned by GetBuffer to change the string contents, you must call ReleaseBuffer before using any other CSimpleStringT member methods.
However, in his case, the contents were not changed, thus the call to ReleaseBuffer is not required.

This is how it should be done:
file.Write(str, str.GetLength()*sizeof(TCHAR));
This is more efficient (no re-allocation), easier to understand and safer (no call to ReleaseBuffer is needed).

I tried your code, substituting constants for strAbc, dDlgResID, dwData, and nCmd, and it worked fine. Before calling Write(), use the debugger to verify that strLine contains what you expect.

Basically because you're passing a junk buffer to write operation.

Try to delete the file and run again your application.
