Re: How to give a File New command from inside a program

14-Jan-07 0:47

I would like to give a command from inside my program to do a File New command.
I tried pApp->CWinApp::OnFileNew() but it tells me I can't access a protected member.
Fair enough, but is there some system command I can give instead?

Thanks,
Ilan

Try this:

::PostMessage(AfxGetMainWnd()->GetSafeHwnd(), ID_FILE_OPEN, 0, 0);

or even

AfxGetMainWnd()-> PostMessage(ID_FILE_OPEN, 0, 0);

Up front it looks like a good idea, but I put in break points and it doesn't reach them. So, I'm still stuck on the proper way to do it.

You're going to have to give more detail if you want help. WHERE did you put the breakpoints?

Sorry, I didn't realize you continued to look at my posts.
I have break points at both OnNewDocument and OnOpenDocument

<br />
<br />
BOOL CCardiacDoc::OnNewDocument()<br />
{<br />
	char buff[100];<br />
	if( m_dataDirectory.GetLength() == 0 && _getcwd(buff, 98)) {<br />
		m_dataDirectory = buff;<br />
		m_dataDirectory += "\\*";<br />
	}<br />
	if (!CDocument::OnNewDocument())<br />
		return FALSE;<br />
<br />
	// TODO: add reinitialization code here<br />
	// (SDI documents will reuse this document)<br />
<br />
	return TRUE;<br />
}<br />
<br />
BOOL CCardiacDoc::OnOpenDocument(LPCTSTR lpszPathName)<br />
{<br />
	m_dataDirectory = lpszPathName;<br />
	int j = m_dataDirectory.ReverseFind('\\');<br />
	if( j > 0) {<br />
		m_dataDirectory = m_dataDirectory.Left(j+1) + "*";<br />
	}<br />
	if (!CDocument::OnOpenDocument(lpszPathName))<br />
		return FALSE;<br />
<br />
	// TODO:  Add your specialized creation code here<br />
<br />
	return TRUE;<br />
}<br />

I see that when I start the program it goes to OnNewDocument. Likewise, before I override the OnOpen, it goes to OnOpenDocument. The function I use is:

<br />
void CCardiacDoc::OnFileOpen()<br />
{<br />
	CString path1;<br />
	int flags;<br />
	CFileDialog fdlg( true, NULL, "dummy entry");<br />
	fdlg.m_ofn.lpstrTitle = "Choose directory";<br />
	flags = fdlg.m_ofn.Flags;<br />
	fdlg.m_ofn.Flags = flags;<br />
	if( fdlg.DoModal() == IDOK)<br />
	{<br />
		path1 = fdlg.m_ofn.lpstrFile;<br />
		int i = path1.GetLength();<br />
		i -= (int) strlen(fdlg.m_ofn.lpstrFileTitle);<br />
		m_dataDirectory = path1.Left(i) + "*";<br />
		AfxGetMainWnd()->PostMessage(ID_FILE_NEW, 0, 0);<br />
	}<br />
}<br />

It never again reaches OnNewDocument. If I would use ID_FILE_OPEN (which I tried), I would expect it to reach my overridden routine, which it doesn't. I really want it to go to OnNewDocument which I why I assume you had a small typo.

Thanks,
Ilan

Well see? That's completely different than what you originally asked.

In OnOpenFile(), instead of posting the ID_FILE_OPEN message, try this line instead:

OpenDocumentFile(path1);

I didn't explain the whole problem. I don't want to open the file the user gives, just to use the directory he gives (because it actually opens a whole bunch of files, not just a single file).
The problem is, what happens when the user "opens" the same file twice? (i.e. he points to the same directory and picks the same file). Windows says it is open and doesn't open it again. Again the problem is the directory structure can be complicated and I'll have to ask for more help, after he has chosen the directory.

In short, I want to use the New command and then there is no problem with the file already being open. The New command would solve the problem nicely (as it does when the program is started).

Thanks,
Ilan

If the FileOpen dialog is only used to select a folder, how does the user specify the filename to open? You're still not sufficiently describing your problem.

It looks like you need to completely redesign your file handling if you're having these kinds of issues. Since I don't know what you mean by "opens a whole bunch of files", I can't suggest an alternative file-handling mechanism.

IlanTal14-Jan-07 4:45

Re: How to give a File New command from inside a program

In fact the user need not specify a file. There is "dummy entry" as a default.

The whole bunch of files can represent different views of a cardiac study, which are all displayed. The trouble is that lately there can be multiple studies in the same directory and those I don't want to display together. I have to make a list and ask the user which one he wants, then I go pick up just the parts of the chosen study.

All this is already working. The only part which bothers me is if he goes back to the same directory to pick another study. If he happens to select the same file, then it is already "open".

(A bit of a lie here. The "dummy entry" doesn't work in the normal open file, as the file doesn't exist.)

I've been looking around and I found another suggestion on how to solve the problem. That suggests to use ID_FILE_NEW up front and inside OnNewDocument distinguish if it is the first time around or not. If not, add my dialog to change the directory. Someone suggested this way back in 1997.

Thanks for your suggestions. I still don't know why they don't work. It may have something to do with the fact that I am in the middle of an ID_FILE_OPEN command.

ID_FILE_OPEN is not a message, it is a command. One could get away with posting a WM_COMMAND message with ID_FILE_OPEN as the menu item.

PostMessage(AfxGetMainWnd(), WM_COMMAND, MAKEWPARAM(0, ID_FILE_OPEN), 0);

Try adding an

#include <afxtempl.h>

to your header file.

Please use the pre tag (above the emoticons) when you post code. And also, whe nyou have < or > characters in the code, replace them by the '<' tag (also just above the emoticons). In your case, the code is unreadable (because it uses templates that are discarded).

One possible solution: did you include the necessary header for the CArray ? Did you also include the header file from your CPoint3D class ?

(please edit your post and correct the formating).

view source won't work for me, so I can't read your code. Either way, I concur with the person who said that you probably don't have the headers included.

Have you tried std::vector ? It's like CArray, only good. You'll still need to include the header, but you'll be writing standard C++ and you'll find it will do a lot of stuff that CArray won't, if you ever need it to

CArray is a template class. You can't create an instance like this:

CArray array; //wrong

It should be

CArray<myclass, myclass&> array;

where myclass is the type of object the CArray container contains.

*EDIT* I just realized you probably had it that way but the angle brackets got axed Smile | :)

Never mind!

Hi Mark,
Thanks a lot for pointing the resource. But i want to know if there is any utility (free or paid) to track dll calls done on my system.

I would like to know if atleast there is any utility to LOG all SQL queires run on a PARTICULAR table in MS SQL..

Thanks a lot..

If you are looking for something to log all queries from a database check the documentation. Most, if not all, database implementations support a way trace all the SQL commands made to their database. That would be a lot easier then injecting your code and logging them yourself.

Even if you can't restrict it to one table, you can log everything and later use something like grep to get just the lines you are interested in. Hope this helps.
