I don't really know MFC that well, but I guess the CMyDialog() constructor returns a pointer to a new object. Sorry, senior moment there, new returns a pointer to the object created.

Hi All,
Is it possible to open the file twice? I am using CStdioFile, i created two objects of type CStdioFile and assigning the same file for both the objects. one file opened for writing(modeReadWrite) the data and the other file opened for reading(modeRead) the data. In this case my application is crashing. please give me some solution.
CStdioFile obj1;
CStdioFile obj2;
obj1.Open("file1.txt", CStdioFile::modeReadWrite);
.....
.....
.....
obj2.open("file1.txt", CStdioFile::modeRead);
.....
.....
obj2.close();
....
...
obj1.close();
Thanks in advance!
Regards,
Anil

Why do you want to do such a thing ? Why don't you simply open and read the full file in memory, make the changes in memory and then write back everything to the file afterwards ?

Yes you can, simply use 2 handles (or objects or whatever your language wants you to use). Be aware of the folloing:
- The OS sees this as file sharing, so open in shared mode.
- You will have 2 independent filepointers.

To Cedric and David: There are many cases opening a file twice can be handy. The simplest example is a Word document on a network. The first user reads it shared, read-write, the next shared, readonly. Be aware many DBMS use this for concurrent access (with some intelligence around).

Hi..
In CView application I am showing a dialog(Like toolbar/ Status bar).
I have to change the dialog background color.
I used the following code. But background color not changing. If i use this same in new dialog application the background color is changing.
ON_WM_ERASEBKGND()
BOOL CTech::OnEraseBkgnd(CDC* pDC)
{
CRect rect; GetClientRect(&rect);
CBrush myBrush(RGB(255, 0, 255));
CBrush *pOld = pDC->SelectObject(&myBrush);
BOOL bRes = pDC->PatBlt(0, 0, rect.Width(), rect.Height(), PATCOPY);
pDC->SelectObject(pOld);
return bRes;
}
How to solve this problem.
Any help will be appriciated..
Thanks...G.Paulraj

| I do not think that this is the message for the dialog's background repaint. Take a look at the WM_CTLCOLORDLG[^] notification. txtspeak is the realm of 9 year old children, not developers. Christian Graus

Hello,
I am using VS2008 and OS Win XP. I create one application and uses the following function for writing the CD and it works fine.
SHGetFolderPath();
CoCreateInstance();
pICDBurn->HasRecordableDrive();
pICDBurn->GetRecorderDriveLetter();
pICDBurn->Burn();
When i deploy this application on OS Windows 2000, these function fails.
Is Win 2000 does not support this API or functions?
If i have to write CD in win 2000, what changes i have to made in this application or any other way to write CD?Abhijit

Usually error handling is helpful in such cases.
However, reading the
Minimum operating systems=Windows XP
info in the documentation [^], is priceless.

Thanks for your help.
Is there any other way to write CD on Win 2000?

Probably there is, unfortunately I haven't found it (for instance IMAPI too are not supported).

Hi,
How to hide the dialogbox in win32. I tried ShowWindow(hWnd,0) in Initdialog()but fails to hide.
|
|
|
|
|
you can only hide a dialog if you have already created it.
A simple way is to only create a dialog if it has to be shown  Press F1 for help or google it.

If the dialogbox is the main window of your application look for the m_nCmdShow member of your CWinApp class. This member could be set in the InitInstance() method of your app.
Here is an article about it: A Simple Method to Control the Startup State of an MFC SDI Application[^]
If it is not the main window try to remove the WS_VISIBLE style from your dialog template.

|
|
|
Handle the first WM_PAINT message and call ShowWindow(hWnd, false); there. Because that's the first message that will be posted to the dialog after it's created.
