If I define STL vector, not bu pointer, but by value
as:
<br />
<br />
typedef vector<CVariableShift> type_DevStrVector;<br />
<br />
struct CVariableShift<br />
{<br />
int i;<br />
};<br />
than how to get copy of stored variable
by iterator?
Only possible bu conversion to pointer ? as :
<br />
<br />
int j = it->i;
<br />
l_VariableShift = *(CVariableShift*)(&it);
<br />
<br />
Is it possible to works without ugly conversion?
thanks.

I think you're asking the following. I have a vector<int> and an iterator of type vector<int>::iterator (or const_iterator). How do I get the value that the iterator points to?
vector<int>::iterator it;
int iVal = *it;

I'm creating a .xls file using a third-party com component. However this component is unable to protect the sheet using a password.
Does anybody knows a way I can protect the sheet using vc++ (without having microsoft excel installed) ?

hello friends,
We are doing a project in vc++ for image processing .We used your class(CXImage) in our project for converting user typed text into transparent GIF image. We used the following steps for our requirement.
Note: Operating System : Win XP Professional ,
Development Tool : VC++ 6.0.
1)Create a memoryDC
2)Created a compatible bitmap with the dialog
3)selected the bitmap into MemoryDC
4)Draw Text on that DC
5) Created a CXImage object and passed Bitmap handle to CXImage member function called CreateFromHBITMAP
6) We used the function Save() to save that image.
But the problem ia that we can insert the Image to Frontpage but the image is not visible.
Following code is extracted from our project
void CTestCXImageDlg::OnCreateBMP()
{
CDC memDC;
CBitmap bitmap;
CBrush brush(RGB(255,255,255));
CFont font;
UpdateData();
font.CreateFontIndirect(&logfont);
if(memDC.CreateCompatibleDC(GetDC()))
{
if(bitmap.CreateCompatibleBitmap(GetDC(),200,50))
{
memDC.SelectObject(bitmap);
memDC.SetBkColor(RGB(255,255,255));
memDC.FillRect(CRect(0,0,200,50),&brush);
CRect rect(60,15,200,50);
SetTextColor(memDC.m_hDC,RGB(0,255,0));
memDC.SelectObject(&font);
memDC.DrawText(m_Text,&rect,DT_END_ELLIPSIS | DT_CENTER );
CxImage img1;
img1.CreateFromHBITMAP((HBITMAP)bitmap.m_hObject);
img1.Save("c:\\imgtest.gif",1);
.
.
.
.
eagerly waiting for your response

Hi, everybody
some one know the algorithm of detecting different regions of two images(with the same size),or give me a link where related information can be found.
My application needs that,but my knowledge about digital image processing is not enough.
Thanks.

IHTMLElement* lpBodyElm = NULL;
lpDispatch = m_WebCtrlPreview.GetDocument();
if(lpDispatch)
{
lpDispatch->QueryInterface(IID_IHTMLDocument2, (void**)&lpHtmlDocument);
lpDispatch->Release();
}
if(lpHtmlDocument)
{
lpHtmlDocument->get_body(&lpBodyElm);
lpHtmlDocument->Release();
}
if(lpBodyElm)
{
BSTR bstrHtml = szHtmlPreview.AllocSysString();
lpBodyElm->put_innerHTML(bstrHtml);
SysFreeString(bstrHtml);
lpBodyElm->Release();

Hi
I have a MFC-dialog program with a list in it. I have assigned F5 as a hotkey to update the list through the RegisterHotKey function. This works fine
But from the main window I want to open another dialog with a different list in it. I want to use F5 as a update-hotkey in this dialog too .. but I cant get it to work. F5 only updates the list in the main dialog.
I thought that a RegisterHotKey registered a hotkey for the whole system so that I can capture it in every dialog in my program ??
Any help is much appreciated !

How are you calling RegisterHotKey()?
A rich person is not the one who has the most, but the one that needs the least.

I do it like this:
In the maindialogs OnInit-function:
RegisterHotKey(GetSafeHwnd(), m_IDHotKey, NULL, VK_F5);
And add this to the messagemap in every dialog that should use the hotkey:
ON_MESSAGE(WM_HOTKEY,OnHotKey)
And the OnHotKey function looks like this:
LRESULT CFingerIDAdminDlg::OnHotKey(WPARAM wParam, LPARAM lParam)<br />
{<br />
}
It only works for the main dialog ... a F5-keystroke in the child window registrates as a F5-key in the main window. I thought that the WM_HOTKEY-message was going to be handled by the dialog that is active ??

Have you used Spy++ to see the messages that are being received by both the main window and the child dialogs?

me think you need to put the handler in all the different dialogs ?

I dont have an extention.
This files are in a UNIX ambient
|
|
|
|
|
What constitutes a shortcut on a Unix box (they used to be called nodes) is different than what constitutes a shortcut on a Windows box. There is no way for a Windows box to "ask" a Unix box if such-and-such file is a shortcut or not.
|
|
|
|
|
That's true. Unless you can execute something like a stat() on the file at the UNIX end, you have no way of determining that it is anything other than a regular file. You can't even tell if it's a file with multiple hard links, much less something more esoteric, like a soft link or a device file.

Hello !
Juste a little question.
What is exactly the difference between delete and delete[] ?
Is the second used to delete memory allocated for more than one element and the first when only one element was allocated ?
Thanks
|
|
|
|
|
delete[] assumes that the block of memory pointed at is an array of (the same kind of) objects where the delete operator needs to call the destructor for each element in the array.

Both c++ commands are used to deallocate memory that was previously created. However, delete [] instructs the compiler that the given memory location is an array of allocated space (usually created using the new [] keyword).
The general rule is to use
delete with new and
delete [] with new []

Ok thanks !
That was what I was thinking about but I wasn't sure

Hi, I need to know how to copy a folder and all the contents within to another location set by the user. Because the folders content is read only, I want to be able to make ReadOnly(FALSE);
Is this possible, please help!
