To make sure your recursion logic is sound, you might try moving count outside of CountFiles(), either by making it global or a member variable.

Good Questions, both of them! Sloppy programming I guess is the answer. Fixed now, thanks!
I've tried the whole global count variable thing as well, I still can't see a way around this... Grrr!

what is telling you there would be 13.301 files?
and how many folders are there?
some ideas:
- hidden files (your code would see them all, or throw an exception, so can't really be that);
- maybe folders also count as files in the tool that said 13301;
- there may be something fishy with empty extensions;
- there might be a difference between * and *.*;
- there is something peculiar (and silly) in the way Windows treats wildcards in extensions; I don't recall the details.
- I wouldn't be surprised if some of the above would depend on the actual file system (FAT, NTFS, ...).
I suggest you try your tool and your code on a pretty small set of files and folders, and experiment a bit.

Hey
I am opening the Disk Defragmenter from inside my C++ WIN32 app using the ShellExecuteEx function.
Now i want to make sure that the Disk Defragmenter is a modal dialog, so that User is not able to click any part of my app.
I set one window to EnableWindow(FALSE), but there are other frame windows which can be clicked by User and then the Disk Defragmenter will go hiding or to back ground.
Is there one generic way of making the Disk Defragmenter a modal window so that nothing else on the back ground can be clicked?
From the ShellExecuteEx function, i can get the process handle to Disk Defragmenter.
Thanks in advance.

You can try blocking using the following
WaitForSingleObject(m_hProcess, INFINITE);
This won't make DD modal, it will just block your app until DD is finished.

I think I know how to do so in .NET, and I assume unmanaged code could do similar things:
- give your app a modal form F, and make it sufficiently large to hold DD's main form;
- let that form F call DD and set DD's main form's parent to F. I assume this function[^] does that.
Now DD itself should behave as a modal dialog to your app.
I have a managed app (C#) that does similar things with e.g. MS Word.

Have you experimented with GetAdaptersInfo(), GetInterfaceInfo(), GetAdaptersAddresses(), GetNumberOfInterfaces(), etc?

Perhaps elaborate on what you are trying to do so that we can help you better.
Also note that Bitmap pictures pad each scanline to a multiple of 4 bytes.
If your bitmaps are 32bit, then you can ignore this.
That is if your picture is 5 pixels wide, each pixel taking 3 bytes (24 bits) then each scanline would be 5 * 3 = 15bytes wide.
Since that is not a multiple of 4 some bytes (1 in this case) are added to align the next scanline.
Note: The MSDN page for BITMAP[^] says they are WORD (2 byte) aligned, but from previous experience I have found that they are DWORD (4 byte) aligned.
This means that you must iterate through bm.bmHeight, and then for each iteration of that, iterate through bm.bmWidth.
BYTE *pBitmapData = (BYTE *)XXX;
int nBytesPerPixel = bm.bmBitsPixel / 8;
for (int y = 0; y < bm.bmHeight; ++y) {
for (int x = 0; x < bm.bmWidth; ++x) {
COLORREF clrRef = *((COLORREF *)pBitmapData);
pBitmapData += nBytesPerPixel;
}
pBitmapData += (nBytesPerPixel * bm.bmHeight + 3) & 3;
}

Actually there is one Picture In Picture( PIP ) module in the application. There is a shadow functionality is available with masking for the front layer. My mask( like heart shape ) is a bitmap file ( of 32 bpp ) which is put in the place of front layer( picture ). It's shadow looks like the same.
We can give shadow color of my choice as well( it is a provision ). Shadow will have selected color. So as it should be shown a transparent look I have used AlphaBlend() function to show transparent and semi-transparent pixels present in mask bitmap.
For the BLENDFUNCTION structure( m_blendfunc ) I given at Initialization
m_blendfunc.BlendOp = AC_SRC_OVER;
m_blendfunc.BlendFlags = 0;
m_blendfunc.SourceConstantAlpha = 0;
m_blendfunc.AlphaFormat = AC_SRC_ALPHA;
We can change the intensity of shadow as well( it's a provision ). It's rage from 0 to 100.
So that In OnPaint() I have changed the SCA value as per intenisty value.
m_blendfunc.SourceConstantAlpha = int( m_intensity * 2.55 );
As per the MSDN I have taken the red, green, blue and alpha value from Source( mask bitmap ) and mix up with destination colors ( of selected shadow color ) by this type of calculation
Src.Red = Src.Red * SourceConstantAlpha / 255.0;
Src.Green = Src.Green * SourceConstantAlpha / 255.0;
Src.Blue = Src.Blue * SourceConstantAlpha / 255.0;
Src.Alpha = Src.Alpha * SourceConstantAlpha / 255.0;
Dst.Red = Src.Red + (1 - Src.Alpha) * Dst.Red
Dst.Green = Src.Green + (1 - Src.Alpha) * Dst.Green
Dst.Blue = Src.Blue + (1 - Src.Alpha) * Dst.Blue
Dst.Alpha = Src.Alpha + (1 - Src.Alpha) * Dst.Alpha
The shadow is not getting proper it's look like some type of animation when I change the intesity.
Are I am making any mistake for taking source and destination colors or there is some mistake in calculation of new colors.
I have tried ur suggetsion of iterating through bitmap height & width but the result is same.

Hi!
How to represent Unicode strings? I want to enter e.g "UserName" in an XML file. How to represent the above string in the XML file using Unicode? I also have to read and display this string from C++ and display its Chinese and Korean representation. How to do this?
|
|
|
|
|
Unicode is merely text, you do not need to do anything special apart from ensuring that your project uses Unicode as its standard for all character based fields. To display Korean, Chinese or any other Asian language you just need to use a font in that specific language.

Hi!
If I've a label called "label1" and its Text(Read from XML file) as "UserName",
then will the following suffice to display "UserName" in Chinese?
label1->Font = "Required Chinese Font"
|
|
|
|
|
It looks like you're confusing UNICODE issues with translation ones. You need to translate the text into Chinese, using the proper UNICODE characters.

As Carlo notes below, you will need the word "UserName" in Chinese to start with.

For storing strings in XML file, you should best encode them as UTF-8.

Korean representation.
By "display" I guess you mean using Win32 API. In that case, you'll need to convert the text you read from the XML file from UTF-8 to UTF-16, set a font that supports the script your text belongs to and draw it on the screen.

Hi All,
i am working on dialog based application,here on the main dialog box on the button click i open the child dialog and perform some action in thread here for reading excel file using excel automation and put the values in list ctrl of main dialog box and after reading i m trying to close chile dialog so i m using EndDialog but here the exception occur.
Unhandled exception at 0x76dc8834 in test.exe: 0xC0000005: Access violation writing location 0x00000018.
please help me how can i resolve this thanks in advance.

How are you creating the child dialog?
EndDialog is used to destroy a modal dialog.
Here is an excerpt from the documentation -
Dialog boxes created by the DialogBox, DialogBoxParam, DialogBoxIndirect, and DialogBoxIndirectParam functions must be destroyed using the EndDialog function. An application calls EndDialog from within the dialog box procedure; the function must not be used for any other purpose.
