It's a Windows Forms Application

|

No, it's a Win32 API call. See this[^] usage example.

I assumed you were building a Win32/MFC application. You should have posted your question in the C#[^] forum.
In any case, use the FileName[^] property to obtain the name of the selected file.

So rather than using an OpenFile Dialog, I create an OPENFILE structure and initialize, then call this->GetOpenFileName and this will open a dialog for me, and i can access the path of the file name if OK is clicked through lpstrFile.
Does that sound right?

Sorry. I just started using Visual Studio this week. I wasn't aware that I was using C# rather than C++. Thanks for all the help

GetOpenFilename() is a function (belonging to no class). OpenFileDialog is a Java class, and a .NET class.

What do you need,exactly?
|
|
|
|
|
Have the openfiledialog return a string, and set the picture box picture to that string.
ex: picturebox->image = "c:/mypic.jpeg";
or picturebox->image = mystringfromopendialog;

What about LogonUser()? As long as you aren't too particular, it'll probably get you by. If not, see here.

Perhaps you could use LogonUser()[^] (followed by a CloseHandle(), if successful)?
Caveat: This is just an educated guess. There may be a safer and more appropriate way to authenticate a user.

I have a login dialog box that will need to be placed over two connected monitors.
1)I see in the MFC Library Reference that I can call CWinApp::SetDialogBkColor to set the background color for this dialog, but exactly how is this called? What if I don't have an InitInstance() member function --- do I need to define one?
2)Also, the login dialog must be modal so that access cannot be gained until an ID and PIN are valid. Is there a way to call two objects of the login dialog and have each one placed over each monitor?
3) Can a dialog box be positioned using CWnd::SetWindowPos(.....). If so, how is this accomplished with two monitors?
Thanks for the assistance.

Hi John,
jparken wrote: I can call CWinApp::SetDialogBkColor to set the background color for this dialog
As per the MSDN documentation, this function is obsolete. To set the background color of the dialog box, you must handle WM_CTLCOLOR. This message changes the color of the specified dialog box only.

This function creating the primary thread (WinMain) for the application. without this function, your application will not be spawned.

i dont know more about this. please refer MSDN for more information. I think it is not a beset practice to show login on two screens.

It's not happening in C++/Microsoft technologies, but also happens with popular languages like and Java and all.

(1) You can use WM_CTLCOLOR or WM_PAINT
(2) Hope I understood your question See CWnd::DoModal()
(3)for set position from a window see SetWindowPos(..) or MoveWindow(...)
I hope its helful for you

I need to send a CString into a parameter that is of LPVOID type. I've tried:
CString stuff = _T("...");
LPVOID info = stuff.GetBuffer();
foo ( info );
stuff.ReleaseBuffer();
but the data is lost. How should I go about doing this?

Try:
foo((LPVOID) ((LPCTSTR) stuff));

I tried that too, same thing. What I am trying to do is send form data to the wininet SendRequest(LPCTSTR, DWORD, LPVOID, DWORD) function. the LPVOID parameter is the POST data that you send with a HTTP Post header.

How are you confirming this?

what does work is something like this:
CString header = _T("Content-Type: application/x-www-form-urlencoded");
CString m_data = _T("target=wininet");
char data[] = "target=wininet";
LPVOID postdata=data;
pFile->SendRequest(header, header.GetLength(), stuff, mdata.GetLength)
basically i'm sending to the URL www.codeproject.com the data to the search form on the main page. The code above will return an html file with the search results.
The calls to SendRequest() with the double cast and the call to GetBuffer() both return html files that have no search results. I'm inferring from this that no post data got sent.

The problem is that I can't set the char data[] in the last example. I have a CString variable that has the POST data in it, however I can't get the data in CString because it returns a const char*, and I can't set that to the char data[]. I also have no idea what the post data will be, and thus can't hard code it as I did in the working example.
That was me hard coding my test. In the release it can't be hard coded.
Is there a way I could effectively do this:
CString m_data = _T("...");
char data[];
data = m_data.GetBuffer();

If data actually had a size associated with it:
char data[100];
strcpy(data, m_data); Or:
const char *data = m_data;
