Hi all,
IDE is VS.7:
I've created a Doc/View project, and the view inherts from CRichEditView.
now when i open a file (OnFileOpen) i know the code behind the scene eventually is
void CDocManager::OnFileOpen()
{
CString newName;
if (!DoPromptFileName(newName, AFX_IDS_OPENFILE,
OFN_HIDEREADONLY | OFN_FILEMUSTEXIST, TRUE, NULL))
return;
AfxGetApp()->OpenDocumentFile(newName);
}
where the OpenDocumentFile of the CWinApp loads the file.
but how do i make the rich edit to display the file content?
thanks in advanced.

Have you looked at the view's OnUpdate() method?

Actually no, i haven't taken a loot at OnUpdate?
can you be more specific please....
i've managed to solved my problem using the StreamIn method of the RichEditCtrl....
and then read the file using the edit callback (saw a code in MSDN)
but, if OnUpdate is better ,i would like to know
thanks again

But doesn't this defeat the whole reason for using the document/view pair? Normally the document holds the data (whether from a New or an Open), and the view "asks" the document for this data.

I suggest you read through the Scribble example on MSDN. It covers most, if not all, aspects of doc/view.

I have created a project in eVC++ with the CPU choice as WIN32(WCE x86).Now I would like to change CPU to WIN32(WCE emulator).Can I do this with out making a new project.

Normally you can.
In eVC -> Right click on the menu bar and display the WCE configuration toolbar. There are comboboxes in that toolbar that let you switch platform, Build configuration and target device. These options can also be set using Build->Set Active Configuration... and Build->Set Active Platform...
I have seen however that sometimes when I did not check a certain Platform when initially creating the project, I had problems adding it afterwards. So now I always check all available Platforms when I create a new project to make it easier for me. (just in case I need to build for a different one later on)
Hope this helps you.
Greetings

ya, I have already tried for these options,but i did not able to change through these options.These options only showing me my pre selected CPU and platforms.
So i feel the only solution is to again create a new project with the required CPU checked..
If there is any other alternative then please help me..
Thanx in advance..

I want to log the clsid that is passed to CoCreateInstance. Can someone tell me how to print the clsid using printf?
thanks!
|
|

CLSID looks something like this, if you open "guiddef.h" file in the Platform SDK:
Not exactly, but it gives you the idea:
typedef struct _GUID {<br />
unsigned long Data1;<br />
unsigned short Data2;<br />
unsigned short Data3;<br />
unsigned char Data4[ 8 ];<br />
} GUID;
So you could print it like:
CLSID cls;<br />
printf("%u,%i,%i,%s",cls.Data1, cls.Data2, cls.Data3, cls.Data4);
this is this.
|

|

Googling for it, I got a better one:
<br />
LPOLESTR sIid = NULL; <br />
HRESULT hr = StringFromIID(rclsid, &sIid); <br />
printf("CLSID = %S", sIid);<br />
thanks!

Where does the icon lies ?. In the menubar, pop-menu or on the view ?
|
|
|
|
|
the icon is on the view .I draw some icon load from file.
I draw some text on the view also. when I select the text,the text's backcolor changed ,and the text is selected.
|
|
|
|
|
You can simply catch the event when mouse is moved on the icon and simply load another icon :P.
|
|
|
|
|
It's a good idea,but I think the icon look like selected when I click it .such as when I click the file folder icon in the WINDOWS XP ,the folder icon's backcolor is changed and it looks like selected.how do I do it?
could you help me?
|
|
|
|
|
Its a all drawing ... I mean if u have any bitmap/icon showing selected status ... You have to create such icon or search .. This is thing out of my scope .. Once u find it whatever way u choose, then u simply load that icon on click.

but the icon can't be output at the end.

Is it a displaying problem or printing problem? I don't know the solution if it is a printing problem.
void OnDraw(CDC* pDC)<br />
{<br />
HICON hi;<br />
hi = (HICON)LoadImage(NULL,"d:\\asd.ico",IMAGE_ICON,0,0,LR_DEFAULTSIZE | LR_LOADFROMFILE);<br />
pDC->DrawIcon(10,10,hi);<br />
}
this is this.

I tried,your solution is not able to resolve my question.
this is my code:
.....
hIcon=(HICON)LoadImage (NULL,iconPath,IMAGE_ICON,48,48,LR_LOADFROMFILE|LR_DEFAULTSIZE);
DrawIconEx(pDC->GetSafeHdc(), x-24, y+50, hIcon, 48, 48, 0, NULL, DI_NORMAL);
how should I do ?
could you help me
|
|
|
|

Your code works just fine. Just make sure that x-24, and y+50 will be inside the client area.
Also make sure that LoadImage(...) does not return NULL.
this is this.
|
|
|
|
|
The x-24 and y+50 is in inside the client area.
The loadImage(...) returns a hIcon,I use this hIocn draw icon on the view ,and the icon can display while printing preview,but the icon is not able to print ,why? how can resolve this question?
I also draw text,but the text could be print
thank you.

See my first response. I never tried printing icons. Of course they show well in the print-preview, but I have no ideas about printing them, so I hope someone else can help you.
this is this.
