You should have mentioned you were using Kentico12. Probably you need to ask the question here: Questions & Answers[^].
In any case it looks .NET stuff, not C++.

I took a quick glance at the Kentico site. Now I know this is about designing web pages - another bit of information you could have shared from the start.

One thing however is important to know: on it's main page[^] Kentico states (under "Disadvantages") that it

ShellExecute open

_Flaviu4-Jun-19 22:28

I am trying to open any kind of file using

C++

ShellExecute(NULL, _T("open"), sPath + _T("\\") + sText, NULL, NULL, SW_SHOWNORMAL);

and is working well, but there a little issue: when I am trying to open an image file, I get always the "How do you want to open this file" dialog, everytime … why ? Of course, when I am trying to open this kind of image file from y windows explorer, is open with my default program, Windows Photo Viewer.

Is there any kind of parameters to put on ShellExecute ? Please note that I use this for ever kind of file, including exe files.

Go to Windows Explorer, right click on one of the files with that type, and check its properties.

I check it, there is no any problem, it is open properly in windows explorer … not in my app, using ShellExecute …

Have you checked that the details in the properties for open refer to the absolute path to your application? What is the return value from ShellExecute when you run the code? What are the values of sPath and sText?

I noticed in the Remarks section of ShellExecute function (shellapi.h) | Microsoft Docs[^] that is is strongly recommended that you call CoInitializeEx to initialise the COM system, before calling ShellExecute. Is that call in your code?

I have tried:

C++

hr = CoInitializeEx(NULL, COINIT_APARTMENTTHREADED);
    if (SUCCEEDED(hr))
    {
        HINSTANCE hInstance = ShellExecute(AfxGetMainWnd()->GetSafeHwnd(), NULL, sPath + _T("\\") + sText, NULL, NULL, SW_SHOWNORMAL);
        if (reinterpret_cast<int>(hInstance) <= 32)// Could not start application
            ::SendMessage(theApp.m_pMainWnd->GetSafeHwnd(), WM_SETMESSAGESTRING, 0, (LPARAM)(LPCTSTR)GetDocument()->FormatHinstance(hInstance));
    }

the same result ...

The documentation states that you should use:

C++

CoInitializeEx(NULL, COINIT_APARTMENTTHREADED | COINIT_DISABLE_OLE1DDE)

But I do not now if that will make a difference. The only way forward is to use the debugger and check exactly what happens at each point. You could also try setting the operation to "open", rather than NULL.

I have tried this:

C++

HRESULT hr = E_FAIL;
hr = CoInitializeEx(NULL, COINIT_APARTMENTTHREADED | COINIT_DISABLE_OLE1DDE);
if (SUCCEEDED(hr))
{
    HINSTANCE hInstance = ShellExecute(AfxGetMainWnd()->GetSafeHwnd(), NULL, sPath + _T("\\") + sText, NULL, NULL, SW_SHOWNORMAL);
    if (reinterpret_cast<int>(hInstance) <= 32)// Could not start application
        ::SendMessage(theApp.m_pMainWnd->GetSafeHwnd(), WM_SETMESSAGESTRING, 0, (LPARAM)(LPCTSTR)GetDocument()->FormatHinstance(hInstance));
}
CoUninitialize();

same behavior … that "How do you want to open this file" is still present when I try to start an image file ...

Sorry, I am out of ideas. But that message suggests that there is no default application registered for the file type.

Just to clarify that statement....

The method you uses does the following.
1. Determine the type of file using the extension.
2. Look up what application the OS (windows) has recorded to open that type of file.
3. Open the file using the application.

However if 1 fails, in that the file type is not known (already specified) then it will ask you for what to open it with.

If you want to explicitly specify some application to open the file with then you need a different method.

If you want to preclude the message in the first place then you will need to write code that first detects if the type is known. However that can still be problematic because if there is a known application for type, and then the application is uninstalled (or otherwise not available) there is no assurance that the type will have been unregistered. So it might still fail to open it.

The strange thing is that this behaviour is present on some PC, and on some PC are not present... and I noticed this behaviour even on Outlook application, on some image attachments ... so, guess is PC issue, not application issue.

Because, as I explained, there is an association on the PC, each PC, which specifies what if anything to open the file with based on the extension.

You should ask more specific questions in order to get help. For instance, what device are you talking of?
