Just found this link. The source code is Borland-specific, but you can figure from it what registry entries to modify.

See here (second response).

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

Write memory bitmap to BMP file?

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.

Help me E_FAIL Error

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 ????

   Generally, this a sign of poor implementation of the component. Any developer that returns E_FAIL instead of an appropriate error code should be shot...! Not that E_FAIL does not have its uses - it does, but clearly not here.

   I would be looking into what might be special about that 11th file - is it on a different device, is it locked, etc.

   Peace!

Hi James
Thanks .
Well I would like to add more points to you .
The files are taken from a delivery folder in a server, say A .
The application that tries to send these files are in system , say B.
And the destination is also a server ,say C, in a remote location , to which B connects via modem direct .
So when B tries to send the files from A to C this error occurs .
And one interesting thing is -> B is a linux call server which is called a PABX in telecom .

Could you please clarify the points ?
a) How will you check whether the file(s) is locked or not ?
b) Will ethreal traces be helpful ?

Thanks in advance

Sorry I typed wrong ...

System B is XP
Server A is sun machine (A is not involved in this problem)

Hi again
I hava another question for you but this i time i'm completly lost.
I need to connect to a database in order for retriving and storing.
I've never done something simmilar before so i have no idea.
i prefer to use mysql database.
i've read something about odbc and thats what i'm willing to use(if u have other suggestions pls tell me)

Any way can anybody tell me what i need to include
and what are the first steps of the code to connect to the database(is it possible to avoid wizards).
Also do u have any good reference on this matter which i can read to get a good understanding of how odbc works.

Thanks in advance

This article is ok:

However, to simplify things you may want to wrap all this ugly ODBC API into a class. This (like so many things around) has already been done. Search CodeProject, I believe there are several such articles.

Hi!!
I have a problem and I'm not founding the solution..

I send a fax via Office Outlook from a vc++ program.
My problem is that if I send it with a profile that hasn't got the coversheet, outlook puts however a white page before my fax only with the line "Subject:...".

I think that I ought to set a mapi property, but I have no idea of what!!

thank you

How do I know which font is used in dialog box

IlanTal14-Mar-06 23:44

14-Mar-06 23:44

I would expect that if I use:
CClientDC dc(this);
inside the code for a dialog box it would pick up the font used for that dialog box. In fact, it doesn't. I had to add:

currFont.CreatePointFont(80, "MS Sans Serif", &dc);
oldFont = dc.SelectObject(&currFont);

and then it measured the text extent correctly. (I got the font name and size from the dialog template.)
Clearly, it won't change unless I change it in the project, but I am curious to know how to pick up the information "automatically".

Any suggestions? Thanks,
Ilan

Thanks. I didn't think it was that simple.
It must be internally this.GetFont(), otherwise I don't know how it could figure out which font I want.

In any case, it works....

You are right - CWnd::GetFont() returns current font for window. This font is not selected automatically in compatible DC on creation.

As an aside, i ran into this earlier this week in a WinCE (PocketPC 2002) app i was working on.
I found that calling CWnd::GetFont() for a CDialog window always returned NULL.

Turns out this is expected (from MSDN WM_GETFONT for WinCE):
The WM_GETFONT message does not return a font handle if the message is sent to a dialog box created by the DialogBoxParam, DialogBoxIndirectParam, CreateDialogParam, or CreateDialogIndirectParam functions.

Exception occurs when dynamically creating control

14-Mar-06 23:43

Hi,
I have derived a class from the CEdit and overided the function PreSubclassWindow(). Inside this function, I called the SetFont function.

The control works fine if this class is made as the control varaible type. But when I Created a object and called Create() function it throws exception

I found its because of the SetFont in PreSubclassWindow.

Is there any way to get ride of this?
or
Is there any function/message for Edit box(other than PreSubclassWindow)where i could do initialization after the window is created?

Plz help
Thanks in advance
