Hi, all
I'm adding items to the list control:
for (i = 0; i < pDoc->GetSize(); i++)
{
LV_ITEM lvi;
CMovieData* pMovie = pDoc->GetMovie (i);
lvi.mask = LVIF_TEXT | LVIF_PARAM;
lvi.iItem = i;
lvi.iSubItem = 0;
lvi.pszText = new TCHAR[]; // this line is 63
_tcscpy (lvi.pszText, pMovie->Name);
movList.InsertItem (&lvi);
lvi.mask = LVIF_TEXT;
lvi.iImage = i;
lvi.iSubItem = 1;
_tcscpy (lvi.pszText, pMovie->GetGenre());
movList.SetItem (&lvi);
}
After program stopping I get a message:
Detected memory leaks!
Dumping objects ->

The 63 line I've marked. Is it possible to delete in some way the strings? Thanks.

The pszText variable only requires the pointer to your displayed string. Because you are already storing the textual information in your document, you only need to set this variable to your string array.
Try this:
for (i = 0; i < pDoc->GetSize(); i++)
{
CMovieData* pMovie = pDoc->GetMovie(i);
LV_ITEM lvi;
lvi.mask = LVIF_TEXT | LVIF_PARAM;
lvi.iItem = i;
lvi.iSubItem = 0;
<font color=red> lvi.pszText = (LPCTSTR)pMovie->Name;</font>
lvi.iImage = i;
int pos = movList.InsertItem (&lvi);
movList.SetItem(pos, 1, (LPCTSTR)pMovie->GetGenre());
}
[EDIT]
This will eliminate the need to create unmanaged memory allocation which resulted in your memory leaks.

In this case, you will need to get a pointer to the underlying string array.
One suggestion would be:
..
lvi.pszText = pMovie->Name.GetBuffer(0);
pMovie->Name.ReleaseBuffer();
..

(LPTSTR) (LPCTSTR) pMovie ->Name
That also works well to get around the limitations of the structure definition.

how do i add arabic language in menu?

Just Enable UNICODE support in your application by using these macro
#ifndef UNICODE
#define UNICODE
#endif
these macro will enable the UNICODE SUPPORT In your application and with help of UNICODE charater set you can easily USE arabic in your APPLICATION.

I`m building a MDI application. I couldn`t iterate through the views. I use :
POSITION pos = CFileManDoc::GetFirstViewPosition();<br />
while (pos != NULL)<br />
{<br />
CFileManView* pView = (CFileManView*) CFileManDoc::GetNextView(pos);<br />
ASSERT_VALID(pView);<br />
pView->GetWindowText(strText);<br />
AfxMessageBox(strText);<br />
}
It only went to the active view. Any idea?

Is it possible that an app is called MDI because it is a multiple DOCUMENT Interface 
However, I think that each of your documents only has one view associated with it, unless you are certain you opened up multiple VIEWS on each document.
You need nested loops to get all views in the program...
Firstly, use CWinApp::GetFirstDocTemplatePosition to get first document template position in the program, and iterate each of the found document templates.
Secondly, use CDocTemplate::GetFirstDocPosition to get first document of the currently iterated document template, and iterate all the documents associated with the currently iterated doeument template.
Thirdly, use CDocument::GetFirstViewPosition to begin iteration of each view associated with the currently iterated document.
In this way, you will get a pointer to each 'view' in your MDI program.

I`m certain. I really don`t know what went wrong.

You will have to debug why your view is not in the view list for the document.
I would place a breakpoint where it is created and start single stepping through the code to figure this one out. There is a member of the document class, I think it is a simple list or array, that contains the views. Your view should have been in that list.

OK, I`ll try that. Thanks.

Hi All,
What are the differences between ordinary variables, references and pointer variables?
I need a description in this area.
Hope someone will help me soon.
TIA,

How can I implement this?
So far I have:
using namespace std;
typedef std::vector<std::vector<unsigned char=""> > USBVECTOR;
// Declare a dynamically allocated vector of QuickUSB Devices
USBVECTOR aDeviceChannel;
// Iterator is used to loop through the vector.
USBVECTOR::iterator iDeviceIterator;
So how can I make aDeviceChannel into a typical 2d array? Then how can I write data to each index in the array (like array[i][j] = blah)
Thanks

Try this technique...
<pre>// Array of arrays of ints
typedef vector<vector<int> > CMultiIntArray;
void TraceDynamicArray(const unsigned int rows, const unsigned int columns)
{
CMultiIntArray aTest;
// Allocate number of rows
aTest.resize( rows );
// For each row
for (int row = 0; row < aTest.size(); row++)
{
// Allocate number of columns
aTest[row].resize( columns );
// For each column
for (int column = 0; column < aTest[row].size(); column++)
{
// Assign a value
aTest [row] [column] = 10 * row + column;
// Trace it
cout << aTest [row] [column] << "\t";
}
cout << "\n";
}
}
// Example usage: Standard C++ Library version
int main(int argc, char* argv[])
{
TraceDynamicArray(3,5);
return 0;
}</pre>

Is there is any way to attach a toolbar to an ActiveX control ?
|
|
|
|
|
Hello Anand,
I think this is not possible.
You can do it if your activeX control gives any method to attach a toolbar to this control window.
One more thing. I think you can develop your own control using the existing one(writing wrapper on the existing one) so that u can add the toolbar at the time of development.
Any way, I am not quite sure.
I hope these info will help you,
Jahfer

i added the toolbar .
but now i display a dialog box when double clicking on the activex control.
it work fine. but when i touch the title bar to move the dialog box it hangs.
please help me.

try a modeless dialog with no title bar (Why you move the dialog in your ActiveX? It is a place holder for other controls.)

can we create an icon for dll file - similar to icon for exe file?
if yes, how?
thx
includeh10

You can put icons into the resources of DLL files.
However, there is typically only a single icon associaed with the DLL file extension at any given time, meaning that ALL dll files get the same icon. Is that what you wanted to change? Or did you think your DLL would get its own icon? If you want your own dll to get a speical icon, you might try writing an icon handler shell extension. I am not sure what yu are trying to acomplish, and it might not be really worth your troubles, your time might be better spent elsewhere, than trying to cirumvent the Windows UI.
