Hello.
How can I find out what files on my computer are being modified? And not by scanning every file. Something like task manager maybe...
Thanx.

Thanx. But that is an executable. I was searching for some source code, or even some main directions so that I can build my own '.cpp'. I only need the path of the files in the form of a string.

It helps to be as specific as possible. That article goes on to say what is required. Creating device drivers is no trivial task.

How about using the CDirectoryChangeWatcher class that is on codeproject ?
|

That would not work unless something about the file was changed.

I am writing a MDI database app using a splitter window (upper pane = parent table) (lower pane= child table) and am unsure as to the responsibilities of each class. I have it working but am always trying to better myself.
I have a database object (CDatabase)
I have a recordset object (CRecordset)
I have a document object (CDocument)
I have several views (CFormView)
I have a CSplitterWnd hosting the CFormViews
I realize the document holds the data. So here are my questions
I have seen an example where the document holds a member variable of both the Recordset and the Database and am currently adopting this scenario.
But which class is responsible for actually creating the recordset or does it matter? I currently have the document creating the database and each formview class responsible for creating the recordset of its pane. My document holds a member pointer of the recordsets created in the view
Is it appropriate to use the UpdateAllViews from the CDocument class to invoke the OnUpdate of each view? Then overide the OnUpdate in the view class to run a requery and other housekeeping procedures. Normally I associate the UpdateAllViews with some sort of visual activity in the Views but with a database it's all about requerying and housekeeping.
Thanks

It depends.
IMHO, it would be much better to hold your CDatabase and CRecordset objects together in the CDocument-derived class of yours because they are essentially serving the same purpose - to link your views to data. However, if recordset objects are subject to heavy dynamic user-invoked changes, I'd normally prefer to associate them with views.
That's what I think, although it's so much more a matter of preference than of being right or wrong...

Thanks,
Does it matter where those recordset objects get instantiated with the new keyword (CDatabase or CFormView)?
|

Yes, it does matter for me. I'd create them immediately where they are used, but also exactly where "main" pointers to them are stored (i.e. those pointers you use to delete recordsets; it's important as this must be done only once and preferably in a function called from the destructor of your CDatabase or CFormView object).
The worst thing to do IMHO is to split the code that works with these recordset objects into several parts based in different classes. Chances are all hell will break loose upon you when:
a) execution flow comes to destruction and oops you overlook a leak or delete objects twice or whatever else...
b) the program swells in size and soon you are no longer able to track down all activities associated with recordsets.
Keep it simple. In the end it's much better to misplace pointers but code consistently keeping in mind this architecture than to make a correct design decision (if there is one) but implement it inconsistently or in a sophisticated manner.

See here (second response).

This is the same as #1, and should happen automatically.

In a MFC dialog based programm, I add a button control, and the corresponding message function is:
void CHhhhDlg::OnButton1()
{
// TODO: Add your control notification handler code here
CClientDC clientDC(this);
CDC memDC;
memDC.CreateCompatibleDC(&clientDC);
CRect rcClient;
GetClientRect(&rcClient);
CBitmap membitmap;
membitmap.CreateCompatibleBitmap(&clientDC, rcClient.Width(),
rcClient.Height());
memDC.SelectObject(&membitmap);
for (int x = 0; x < rcClient.right; x ++)
{
for (int y = 0; y < rcClient.bottom; y ++)
{
memDC.SetPixel(x, y, x < y ? RGB(255, 255, 0) : RGB(255, 0, 0));
}
}
clientDC.BitBlt(0, 0, rcClient.Width(), rcClient.Height(), &memDC, 0, 0, SRCCOPY);
}
Now, I want to comments the last statement, and save the memeory bitmap (memDC) to a BMP file.
How can I achieve this objective.
Thanks!

if you want to save bmp file use CImage::Save

Hi all,
i have been working on incorporating crystal reports into an mfc application. I am able to call the RunReportWizard method in the following way.
/////
m_Application->RunReportWizard(m_Report," ");
//where m_Report is IReportPtr and m_Application is IApplicationPtr.
Its working. but is it the correct way of calling. The second parameter in which i am passing an empty string must specify the datasource. Can anyone also please tell me how can i pass only a certain type of data connection to this method. the wizard shows all the available connections.
Please help.

HI all
I have an application which uses a Filetransfer module (.tli file is involved while i debug) .
And a function raw_SendFile fails with return value of 0x80004005 (E_FAIL) when it tries to send a file.
To give more info : This function is called N times to send N files , and it properly sends say 10 files . And exacltly when it sends the 11th file named ramdisk\rd.gz it fails . And everytime this is reproducible and exacltly at this file , this function fails .
And my search in MSDN about E_FAIL says "Unspecified error" . What is this unspecified error ?
How can I solve it ?
Can anyone please help me ????
