Hi
I am developing a band for Windows Explorer and I want to get notified when the current folder changes. Looks like IExplorerBrowser provides the notifications I need, but I can't get that interface in my SetSite function. I can get IShellBrowser:
STDMETHODIMP CExplorerBand::SetSite( IUnknown* pUnkSite )
{
if(pUnkSite)
{
CComQIPtr<IServiceProvider> pProvider=pUnkSite;
CComPtr<IShellBrowser> pShellBrowser;
if (pProvider)
pProvider->QueryService(SID_SShellBrowser,IID_IShellBrowser,(void**)&pShellBrowser);
}
return S_OK;
}But I don't know what to do to get IExplorerBrowser. I tried QueryInterface on pUnkSite and on pShellBrowser. I tried calling QueryService with IID_IExplorerBrowser and different service IDs. Nothing seems to work.
I'm starting to think that IExplorerBrowser is only intended to be used to host an explorer window in your own application because there are many examples how to create a new instance but not how to get an existing instance.
Any ideas?
Thanks
Ivo

hello
I want to read and place a .bmp or .jpeg from the disk and create a .doc word file in visual C++
controlling its nature [text wrapping, size etc] is crutial.
please suggest an api or coding

you could use COM automation to do that.

How to join two programes?
I’ve got two good fuctioning programs. The first one counts combinations with giving the elements of them. There are 180 elements in each combination. Here’s the code:
<code>#include "IndexCombination.h"
#include <iostream>
#include <string>
#include <vector>
#include <algorithm>
#include <iterator>
#include <map>
#include <sstream>
#include <mem.h>
#include <conio.h>
using namespace std;
using namespace stdcomb;
bool GetNextComb(std::vector<unsigned int> &vi);
struct Element
{
char name[6];
int numbers[30];
char chain[90];
};
const Element elements[] = {

I’d like to join them in one program. The Output should look like this:
Combination number 1
Number 3 occurs 6 times
Number 48 occurs 7 times
Number 0 occurs 8 times
Combination number 2
Number 5 occurs 6 times
Etc.
What kind of counter or what loops should I use to successfully combine these programs?

Why the hell should I? You can't be bothered to make any effort beyond cutting and pasting your homework problem into the forum; you're too lazy or stupid to make even the feeblest of attempts on your own. So why the hell should I?

Because that's you who says 'I'm clever', that's obvious at the first sight. I personally might be even called stupid, because programming isn't what I like most. Just have to do it. But I can assure you I'm not a stupid person at all. I can do lots of things and I'm not a snob. If you don't want to do it, don't do it. Just show off replying to other posts in the same way. Good luck!

Right now you've got two separate main() functions. How about renaming each of those to something more appropriate, and then create a new main() function that calls each of them?

Why do you keep repeating this question? If you want to draw a butterfly then I would suggest you get some books and learn about graphics programming.

Hi,
I got the process ids of the excel application instances and I need to get windows handler for that.
I tried with AccessibleObjectFromWindow function as below, but I'm getting E_FAIL in hr. Any help is appreciated. Thanks in advance.
HWND hwnd = (HWND)FindWindow(_T("XLMAIN"), NULL);
Excel::Window* pWindow = NULL;
HRESULT hr = AccessibleObjectFromWindow(hwnd, OBJID_NATIVEOM, __uuidof(Excel::Window), (void**)&pWindow);
|
|
|
|
|
If the excel is executed by you, you can get more info by CreateProcess() to run the excel.
or when multiple excels are running, which one you can get?
|
|
|
|
|
Main aim is to get the window handlers of the existing excel application instances. If there are two excel applications opened, I need to get the window handlers for those two instances. From the window handlers, I need to get excel application pointers. Hope you understood the scenario. Pls let me know if you need more clarification
|
|
|
|
|
I did something else, hope it help.
EnamWindows() can get all top level windows, in your case, excel is top one, maybe you can use the function to get more info to find excels.
