Hi,

So , I cannot use CImage in VC++ 6.0

Is there any way put a JPEG image to my Dialog background.

I tried to use "CBitmapPicture" class provided with one of the codeproject article.

But It uses a static picture control to display the JPG file.

But when I used it in my project, I got an error.

How will I load a JPG image and fill my dialog background without using static controls?

Can any one help me ?

thanks in advance.....

You can use OleLoadPicture or GDI+(Graphics and Image::FromFile(...) instead CImage class

What type of application are you working on? MFC, SDK
I think that CImage class is provided in VC7.0(.NET 2003)

You need to include AtlImage.h

Hamid_RT28-Jul-06 21:53

28-Jul-06 21:53

And for CDC you need to Afxwin.h

use GetDIBits to create a DIB from the HBITMAP
then, fill out and write a BITMAPFILEHEADER
then write the DIB

that's it

Why donchoo take a peekchur mayn?
OK, cleeeeek

I searched for a solution but I couldn't find one. Probably what I'm looking for is somewhere out there but I can't find it. I don't like that I have to post a question here or anywhere and bother you with my problems but I'm sick of nasty bugs (very nasty). So here's the problem:
I create a directory with CreateDirectory(path,NULL) ,then I make a few folders in that directory and after that I try to delete that first directory.
And what happens - an error window pops up and says it cannot delete the folder because it is used by another program or person (mine ofcourse). I think this is caused by some unclosed handles maybe. I don't know. Damn nothing works when I want it to work. I'll be very greatfull if someone helps me. And this problem occurs only when I make new folders in that one folder. If it's empty
it's no problem to delete it. Unfortunately I'm not a programmer (yet) and I can't fix all the bugs.

...

After a few hours:
I fixed the bug. And I'm very sorry that I had to post a question that I could answer my self, but at the when I posted it I didn't knew the answer ofcourse. I'm sorry again for the disk space my question takes. It was a pretty simple mistake, but nasty. When I was checking do folders with the default folder name "New Folder" exist, I had to open a handle to the folder
to check if it existed. And I didn't close that handle. That was my mistake. Silly me. And here is the code that finds a name (that it's not already in use by another folder) for the new folder:

do{
CString num;
num.Format("%d",count);
newDirName=path;
if(newDirName.GetAt(newDirName.GetLength()-1)!='\\'){newDirName+='\\';}
newDirName+="New Folder ("+num+")";
ftest.HCloseHandle(); //Note: This is line I was missing before.
ftest.HSetFileName(newDirName);
count++;
}while(!ftest.HGetFileHandle());

I again apologize for posting this question. I hope no one's angry at me.

After a day(approximately):
I liked Gary R. Wheeler's reply. Thank you for your words man.

When I wrote the above stuff it was 2 or 3 am and I was tired, nervous and sleepy. I was amazed when I saw how many syntax errors I have made.

There's no need to apologize. You asked a reasonable question in a polite fashion. When you found the answer yourself, you updated your post so that people would know it. If you feel it was a 'silly mistake', that's OK; you'll remember better next time.

The questions that piss people off are the ones that ask for homework to be done, 'demand' a response, or insult a responder. We're not here to do your homework for you. Telling me to 'give you the source code by 3:00' (note no mention of the word 'please') doesn't instill in me a priority to answer the question for you. I've had posters tell me I was an idiot when I told them what they were trying to do was the wrong approach, and they needed to switch to another method. You can imagine how motivated I was to continue helping them Roll eyes | :rolleyes:

.

The other class of annoying questions are those that could be solved by a simple search through the MSDN[^] or even Google[^]. Those of us who like to answer questions on the CP forums expect you to have at least tried to answer the question yourself. You did that, in fine fashion.

Get a pointer to a property page?

DanYELL28-Jul-06 10:25

28-Jul-06 10:25

Im in any of the functions in the Doc.cpp file.

I can use this code:

<br />
CFrameWnd	*pWndMain = (CFrameWnd *)AfxGetMainWnd();<br />
ASSERT(pWndMain != NULL);<br />
<br />
CDocument *pDoc = pWndMain->GetActiveDocument();<br />
ASSERT(pDoc);<br />
	<br />
POSITION pos = pDoc->GetFirstViewPosition();<br />
CView *pView = NULL;<br />
<br />
while (pView = pDoc->GetNextView(pos))<br />
{<br />

to get a pointer to a CFormView or CDialog that I might have. The
CView *pView pointer lets me access individual items in that CFormView.

If my CFormView has a property sheet with a few property pages, how can
I get a pointer to these property sheets from CDoc? I have:

CView1PropertySheet* m_pView1PropertySheet;

under my CFormView, but I cant see it and cant access it using the
pView pointer that I created this way.

Im stumped.

Please, any response any one can give me will be greatly appreciated.

Sincerely,
Danielle Brina

Re: Get a pointer to a property page?

Zac Howland28-Jul-06 10:35

You will need to add an accessor method to your view class to return the pointer to your sheet:

CPropertySheet* CMyView::GetPropertySheet()
{
	return m_pView1PropertySheet;
}

To get access to the pages, you can use CPropertySheet::GetActivePage or CPropertySheet::GetPage (see MSDN).
