Yes, see RegSaveKey().

great  with this i can do my 2 snapshots (are they .reg files ?)
but how to compare and extract differencies from the 2 snapshots ?

That's determined by the second argument.

The same way you would compare any two files. For a quick & dirty approach, you could capture the output of fc.exe.

fc.exe is it included in windows ?

As far as I know, it's part of the standard installation.

nice
but the second argument you mentionned is just the filename not the fileformat, i'd need text file format (like .regs are)

Which is what RegSaveKey() does.

no it saves a .dat file which is (i verified it with notepad) a binary file not a text file : a proprietary fileformat

My bad. I was thinking of the "export" feature of regedit.

oh it can interest me too 
i'd like a commandline export feature from regedit, does it exist ?

No, regedit does not support command-line arguments.

is there another way to extract .reg files from commandline ?

Other than rolling your own, not that I know of. Using the registry API, it wouldn't be that difficult.
If you are considering doing this for the sole purpose of comparing two registry keys, don't bother writing to disk first. That would be just too much time. Write to some data structure in memory instead.

Guys,
I am attempting to take a drawing context, basically the entire area of a dialog box and save it as a bitmap so that I can open it up in Paint. I understand that I might be able to take a screen shot using Print Screen, but I only want the drawing area, not the menu and borders etc... This is my code, as far as I can tell it works until I make the call to GetDIBits. This function returns 0, and when I call GetLastError() it returns ERROR_FILE_NOT_FOUND. The function GetDIBits remarks that I must pass an bitmap that isn't selected into a DC. Could somebody give me a hint about where I am going wrong? I am not sure how to unselect an object from a DC, or how to create a copy of the DC after I Blt in the viewing area.
<br />
GetClientRect(hDlg, &rc);
<br />
hdc = GetDC(hDlg);
<br />
blankDC = GetDC(NULL);<br />
<br />
rc.bottom -= (GetSystemMetrics(SM_CYHSCROLL)+GetSystemMetrics(SM_CYEDGE));<br />
<br />
hSavedXYContext = CreateCompatibleDC(hdc);
hSavedXYBitmap = CreateCompatibleBitmap(hdc, rc.right-rc.left,rc.bottom-rc.top); <br />
<br />
hUnSelectedBitmap= CreateCompatibleBitmap(hdc,rc.right-rc.left,rc.bottom-rc.top);<br />
<br />
SelectObject(hSavedXYContext, hSavedXYBitmap); <br />
<br />
BitBlt(hSavedXYContext,0,0,rc.right-rc.left, rc.bottom-rc.top,hdc,0,0,SRCCOPY);<br />
<br />
<br />
<br />
<br />
GetObject(hSavedXYBitmap,sizeof(BITMAP),(LPSTR)(&bmp));<br />
<br />
cClrBits = (WORD)(bmp.bmPlanes*bmp.bmBitsPixel);<br />
<br />
cClrBits = 32;<br />
<br />
pbmi = (PBITMAPINFO) LocalAlloc(LPTR,sizeof(BITMAPINFOHEADER));<br />
<br />
<br />
pbmi->bmiHeader.biSize = sizeof(BITMAPINFOHEADER);<br />
pbmi->bmiHeader.biWidth = bmp.bmWidth;<br />
pbmi->bmiHeader.biHeight = bmp.bmHeight;<br />
pbmi->bmiHeader.biPlanes = bmp.bmPlanes;<br />
pbmi->bmiHeader.biBitCount = bmp.bmBitsPixel;<br />
<br />
pbmi->bmiHeader.biCompression = BI_RGB;<br />
<br />
pbmi->bmiHeader.biSizeImage = (pbmi->bmiHeader.biWidth + 15)/16 <br />
* pbmi->bmiHeader.biHeight * cClrBits;<br />
<br />
pbmi->bmiHeader.biClrImportant = 0;<br />
<br />
<br />
pBitmapInfoHeader = (PBITMAPINFOHEADER)pbmi;<br />
<br />
lpBits = (LPBYTE) GlobalAlloc(GMEM_FIXED,pBitmapInfoHeader->biSizeImage);<br />
<br />
GetDIBits(hdc,hUnSelectedBitmap,0,(WORD) pbmi->bmiHeader.biHeight,<br />
lpBits,pbmi,DIB_RGB_COLORS);<br />
<br />
Thanks in advance,
Joe

Before you make a call to GetDIBBits call SelectObject again to release your selected bitmap.

like this:

// when you're done:

Another way to deselect a GDI object is to first save your DC context with CDC::SaveContextDC then restore it with CDC::RestoreContextDC when you finish with the objects you selected.

I have one handle of DC which contains Bitmap Data I want to save this Data
in File How to get it done.
Shall I use CArchive Class if yes then How???
pls anybody having knowedge regarding it pls let me know .It's urgent

There's no built-in serializaton for DCs or bitmaps.
Saving a DC to a file wouldn't be of any use since the DC wouldn't be valid when read from the
file.
Probably the easiest way to save the bitmap to a file is to
1) use SelectObject() to restore the DC's original bitmap and obtain the HBITMAP for the bitmap
you want to save
2) create a CImage object
3) Use the CImage::Attach() method to attach the HBITMAP to the CImage object
4) Use CImage::Save() to save the bitmap to a file

Hi,
Enumerate through the items and test each one;
CListCtrl &ctrl = GetListCtrl();
for (int j = 0; j < nCount; j ++)
{
if (ctrl.GetItemState(j, LVIS_SELECTED) == LVIS_SELECTED)) {
}
}
