Perhaps I don't give a reasonable ideea, but you can look where MFC implement CScrollView::ResizeParentToFit(..) and reproduce the code ...

Aside from the top value always being 0, lesser than what? Unless the window is borderless (e.g., desktop), it can't occupy the entire screen. Things like borders, scroll bars, captions, etc take up room.

Sorry, that was suppose to be right dimension.
I know about the frame / border, what I am asking are the right / bottom dimesions not being SAME as the actual view screen client dimensions.
For example - when I build a new window, with frame, in the default view ( parent frame) and use the view client rectange ( of the default view area) to size it - these dimesions are not the same as the actual view area. They are smaller.
I suppose I should get the new window dimesions AFTER it is maximized. Than it should show larger size than when originally sized to the client area.

Another ideea is to send to the view a menu->window->tile message, and your view will spreadsheet along mainframe ...

Good idea, but still does not answer the original questio. SOrry.

It needs to write string to the file.
But it Open file return FALSE, GetLastError() = 3.
m_File2Write.Open(webRes.strLocalFile, CFile::modeCreate | CFile::modeWrite | CFile::shareDenyWrite))
{
DWORD error = GetLastError();
return -1L;
}
The file does not exists, but I think it will create a file. I do not know why Open file falied.
-----------------------------
Now I know why. Because there is the chararcter '-' in the file name. Such as 12-444.html
But if use the explorer to create file 12-444.html, it is ok. Why use CFile, it error?

WinError.h:
OK the file does not exist and you want to create it, but what about its folder?
Veni, vidi, vici.

I know 3 means can not find the path, but I donot know why.

I would check with the debugger the runtime value of webRes.strLocalFile.

Having some Gollum flashbacks, are we?
Seriously, though, what is the value of strLocalFile?

You are trying to create a file and a path. Not possible with Open().

In the above code you do not test the return value from Open, so the return value of GetLastError() does not mean anything.

The full code is as follows:
if (!m_File2Write.Open(webRes.strLocalFile, CFile::modeCreate | CFile::modeWrite | CFile::shareDenyWrite))
{
DWORD error = GetLastError();
return -1L;
}
Just Open return FALSE, it will call GetLastError(), error is the err code.

Perhaps CFile doesnot support file name with character "-".
|
|
|
|
|
|
Of course it does, Windows would never work if that was the case. Can you show the exact string you are passing to the Open() call, as it exists in your code?

Certainly,
strLocalFile is a CString type;
strLocalFile = _T("d:\temp\1FC69DCC-3B54-4DE4-8AEB-7094D0B23E01.html");
if (!m_File2Write.Open(webRes.strLocalFile, CFile::modeCreate | CFile::modeWrite | CFile::shareDenyWrite))
{
DWORD error = GetLastError(); // where error is 3
return -1L;
}
|
|
|
|
|
Try:
strLocalFile = _T("d:\\temp\\1FC69DCC-3B54-4DE4-8AEB-7094D0B23E01.html");
The difficult we do right away...
...the impossible takes slightly longer.

As the other Richard points out you have not escaped your backslash characters in the string, so the actual string being sent to the Open() function contains invalid characters. The "\t" part of the string is replaced by a tab character by the compiler.

Sorry,
The active value of variable strLocalFile is "d:\temp\1FC69DCC-3B54-4DE4-8AEB-7094D0B23E01.html".
I forgot to transmit it to c++ code. In c++ code, '\' should be '\\'.

That's not completely true.

Hello,
How to define horizontal profile
For EX; i have a vertical bar on an image of thickness - 40 Width & Height 400 . the possibility of getting defects also possible in bar. so i want to create a horizontal profile of length 0 to 40 ( by taking the uniformity and average pixels from the all 400 length)
so the horizontal profile is going to my reference profile - to verify the defects later .
i don know whether you guys under stand my question..but post me if you didnt
How to create a horizontal profile ??

Gday,
There's a page at Wikipedia on Fixed Pattern Noise, see here[^].
I think you are (probably) interested in calculating the DSNU.
If this is the case, I believe it involves the following steps.
1. Initialize totalLuminosity to 0.0
2. Create an array of numToProcess (400) elements - lumArray
3. Get pixel value
4. Convert colour(RGB) to HSL (Hus Saturation Luminosity)
5. Add the Luminosity value to totalLuminosity
6. Set lumArray[curPixelNum] to Luminosity
7. If #pixels processed < numToProcess(400) goto #3
8. Divide totalLuminosity by numToProcess(400) - this is your avgLuminosity
9. Create a second array with numToProcess (400) elements - diffArray
10. For each element in array from step 2, set difArray[i] = avgLuminosity - lumArray[i]
This will give you an array that tells you the difference between the brightness of each pixel and the average brightness of all pixels in the line.
Cheers,
S.
