Hi
Does anyone knows if it possible to open a .txt file in main() with the usual
ifstream in1("input.txt", ios::in) written in the main() body, and then pass to a certain function or class member function a pointer pointing to the first character of the file, without having to open the "input" file from this function. If this is not possible, how can I ask the function through some argument to open itself the file? (the function should open the file even is his name is not "input", the name could maybe be given as argument?...)
Thanks

Do like this. Open the file using following code,
ifstream fin;<br />
fin.open("input.txt", ios::in);
now pass this fin to your function.
You should declare your function lile this,
your_function(ifstream &in, ...);
The in will contain address of fin. So you can perform file I/O operations using in
In case of any proble, let us know.
Good luck

Dear All,
How can I change views of CView type to CScrollViews?
This I dont want at runtime but at designtime.
What changes have to be made?
Do I have to change other OnDraw alogirthms too? since Here I would have to take consideration of available view window rect.
Best regards,
pathak

Modify the view's .h and .cpp files.

very easy.
1)create a new project with CScrollView as view.
2)change CView to CScrollView for old project
3)compare 2 projects to see what default functions etc you should add to old project.
anyway, backup old project first

Hi,
I have lines places. I want to identify lines by clicking on them.
Many onLButtonDown I can scan the array of all the lines and see
whose vertex is nearer and get the line.but this may not be correct always.
How about mouse sticking in between the two vertexes, suppose I want to move the line.
Thanks

And what is the question exaclty ?

Why ? What is the problem ? You pick the line that is closest to the point where you clicked. You can still have a maximum distance (if none of the lines is closer than a certain distance, you don't pick any of them).

I don't understand... If the point is precisely between two line, pick one at random (it is stupid for the user to click at a point like that also  )

Cendric,
I want dynamic effect
myline (with vertexes 1, 2, 3 which are stored in the array in the document)
1------b-------2-------------------3
\
\
\
\_\
1------b1-------2-------------------3
Now user identifies line at point b, (remember point b is between 1 and 2 and was not stored in the array. so effect should be like.. whole line moves along with mouse (rubberband effect is expected here and line should seem like it has stuck to mouse at point b) , now user keeps the line at point b1.
and line array gets updated with new points . Its a simple move line command.
But how to achive this graphical command through mfc is a question to me.
I hope , I am a bit clear to you this time.

You can use a boolean in your view class to specify if a line is being dragged or not. Then, you can also keep the data of the line being dragged: the line data plus the point on which the user has clicked. By point, I think the easiest to represent it is to hold a percentage position on the line.
Does that answer your question ?

But in the first place how to select the line object at the point , suggest me some alogirthm in detail.

Hi,
Mine is a graphic application.
When I go for printing, my graphic objects (lines rectangles etc) look
very small
as I have used the mapmode as MM_TEXT. So all of them look very small
on the printing page. I dont want to use MM_LOENGLISH as I could end
up makin huge changes in my application. How to sort this out. How to
have scalled print, preview.
Also white color elements are not displayed. so I am using (i hope its
correct)
void CMysplashView::OnPrepareDC(CDC* pDC, CPrintInfo* pInfo)
{
..
pDC->SetROP2(R2_BLACK );
..
}
thanks,
Lee

if u use MM_TEXT mode, u don't know printed size, because paper is in physical unit - such as mm, inch.
MM_TEXT (pixel) is not valid for paper.
set it as MM_LOENGLISH.
for a project needed to be printed, picture (text, image etc) on screen should be in MM_LOENGLISH aslo, otherwise, looking on screen is totally different from on paper.

You can use MM_ANISOTROPIC and set the scaling factor yourself. This method allows you to even setup positive x and y axis values, mimicing MM_TEXT.
onwards and upwards...

I am having a listctrl (Report view ) here I added some images
m_pmyImageList->Create( 30, 15,TRUE,5,2);
CBitmap bm,bm1;
bm.LoadBitmap(IDB_BITMAP_VIEW);
int i1 = m_pmyImageList->Add( &bm,RGB(0,0,0));
bm.DeleteObject();
bm.LoadBitmap(IDB_BITMAP_TURBO);
int i2 = m_pmyImageList->Add(&bm,RGB(0,0,0));
bm.DeleteObject();
and color of selected item text is
if ( CDDS_ITEMPREPAINT == pLVCD->nmcd.dwDrawStage )
{
COLORREF crText,crBack;
if ( (pLVCD->nmcd.dwItemSpec ) ==iListPos-1 )
{
crText = RGB(255,255,255);// Selected Text color
crBack= RGB(0,0,127);/// Selection back color
}
and now the images are not getting selected. I want to make them transparent (matches with the color of selection)
How can I? Please help me .
Thanks in advance

void CTrussListEditorView::OnCustomdrawList1 ( NMHDR* pNMHDR, LRESULT* pResult )
{
NMLVCUSTOMDRAW* pLVCD = reinterpret_cast<nmlvcustomdraw*>( pNMHDR );
// Take the default processing unless we set this to something else below.
*pResult = 0;
if ( CDDS_PREPAINT == pLVCD->nmcd.dwDrawStage )
{
*pResult = CDRF_NOTIFYITEMDRAW;
}
else if ( CDDS_ITEMPREPAINT == pLVCD->nmcd.dwDrawStage )
{
COLORREF crText,crBack;
if ( (pLVCD->nmcd.dwItemSpec ) ==iListPos-1 )
{
crText = RGB(255,255,255);// for same color use 0 instead of 255
crBack= RGB(0,0,127);
}
else
{
crText = RGB(0,0,0);
crBack= RGB(255,255,255);
}
pLVCD->clrText = crText;
pLVCD->clrTextBk = crBack;
SetBkMode(pLVCD->nmcd.hdc,TRANSPARENT);
// Tell Windows to paint the control itself.
*pResult = CDRF_DODEFAULT;
}
m_Cancel.SetFocus();
}
This is the actual function
or I just need is a transparent bold rectangle of blue color around the row to highlight the selection
Thanking you

Its not possible to do that in this way...here u r only trying to change the background color..
I think u have to draw the item by user self if u want to achive that. CImageList have function to draw the image with blending..

I have developed a windows shell extention to send disc files as attachments using default mail client.I have used MAPI dll's SendMail function.
It works fine for single attachment but am not able to send for multiple attachments(this problem happens only with *****LOTUS NOTES*****).Can we send multiple attachments using SendMail function?If so how(any sample code)??
I used SendDocuments to do the same with Outlook and i was able to send multiple attachments.
How do we send Multiple files as attachments in Lotus Notes using any MAPI Dll funtion?

What is the difference between SendMail() and SendDocuments()? What happens if you use the former on a machine that uses Outlook instead of Notes?

The subject of this thread does not quite match the body of your post so I'm not real clear on what it is that you are after. 
Is WM_QUERYENDSESSION or WM_ENDSESSION perhaps what you are after?

I see applications that like your question that monitor computer
but how to hide your program from TaskManager it's show in this program
(I think you can write this program but it's difficult.)
