Whats result when run this code?

OPENFILENAME ofn;       // common dialog box structure
       char szFile[260];       // buffer for file name
             HWND hwnd;              // owner window
                HANDLE hf;              // file handle
ZeroMemory(&ofn, sizeof(ofn	));                            
                ofn.lStructSize = sizeof(ofn);;
                ofn.hwndOwner =m_hWnd;
                ofn.lpstrFile = szFile;
	ofn.lpstrFile[0] = '\0';
        ofn.nMaxFile = sizeof(szFile);
ofn.lpstrFilter = "All\0*.*\0Text\0*.TXT\0";;
          ofn.nFilterIndex = 1;
           ofn.lpstrFileTitle = NULL;
                ofn.nMaxFileTitle = 0;
 ofn.lpstrInitialDir = NULL;
ofn.Flags = OFN_PATHMUSTEXIST | OFN_FILEMUSTEXIST;
if (GetOpenFileName(&ofn)==TRUE)                                 
hf = CreateFile(ofn.lpstrFile, GENERIC_READ,0, (LPSECURITY_ATTRIBUTES) NULL,OPEN_EXISTING, 
FILE_ATTRIBUTE_NORMAL,(HANDLE) NULL);

Hello,

I am creating an outline font as below, and use it with PrintOutlineString, when i use these functions without DIB Section (which i use for printing) it works. However, when i use the DIBSection, i cannot display texts.

May be a bit off-topic in this forum, however if anyone used both together and how?

Thanks in advance.

Bekir.

CFormView-based (SDI/MDI) and dialog-based refer to the architecture of the app - an app can be one or the other, but not both. You can display a dialog from a CFormView-based app, but you can't display a CFormView from a dialog-based app. If you had a separate CFormView-based app, then of course you could start it from a dialog-based app - is that what you want to do?

Best wishes,
Hans

I have explained how to open a CFormView from a MDI, search in forum posts with autor (Nelek) and keywords (Child Window). Part of the code will be usefull. But you will have problems with some parts because you don't have Doc/View relationship. But at least you have an idea about how it should be made.

It sounds as though you want to start one application from within another. Correct? If so, check out CreateProcess().

Hi amit,

It will follow the below steps

1) x-= (--x) - x--; // Decrement x by one.
2) x-= ((--x) - x)--;// subtract x fom x.
3) (x-=--x - x)--;// Subract reult of above opertaion from X in the left side of =.
4) (x-=--x - x)--; // Now decrement the x by one.

so the results becomes 6.

HI nave ,
you are absolutely right dear the answer is 6.But
can you kindly explain with value . because suppose

Naveen.R wrote:
1) x-= (--x) - x--;

The value of x is 7.
here now the value is 7 for all x is it?
means ,

Naveen.R wrote:
2) x-= ((--x) - x)--;// subtract x fom x.

how can I follow the step 2
(7-7)--
will it zero or what ??? D'Oh! | :doh:

then will x will zero or the value 7 will still exist.

means,
7-=(7-7)--
//my question is here whether the value of x will zero here.then what is the value of x on LEFT SIDE. because right side I got zero right.

now
(7-=0)--

as go with logic....
now as x=x-0 means (7=7-0)--
then after it will decrement and the result 6.
I understand this way .but

I thought about the x value ???? is zero or 7 at step 2.

thanks nave

Yes.

amitmistry_petlad wrote:

yes it will be zero. But the value of X is still the same(7);
that line can be broken into the following to lines.
x-= 7 - 7;
x--;
