I have an idea to dynamically set the window pos to center.
If I have the line height then can calculate the window pos.
And also set the visible line count to 3.

If you are wanting to center the actual edit control within its parent, you'll need to use MoveWindow() or SetWindowPos(). If you are using MFC, check out the CWnd::CenterWindow() method.

This sounds like an owner drawn control to me, unless the richedit box has a property to centre the text.

You can use MFC CEdit::GetLineCount() or the Win32 Message EM_GETLINECOUNT to get the number of lines.
--> . If the number of lines is three or less it should come the center of the dialog vertically.
I can't understand your question properly. do you meant to say if the number of lines are 3 or less, you don't want any scrollbar?

It sounds like you need to use the ES_CENTER and ES_MULTILINE styles.

Hello there guys.
Using VC++/MFC, I successfully created a new html file, but when the application was launch, an empty window appeared. The html created didn't display on that window.
For more details:
Inside of the MyAppView.cpp ::OnInitialUpdate(), a function is called that will create a html file(for e.g. CreateHtml("./test.htm") )where "test.htm" is the htm file created. Then Displaying the html using Navigate("file://..../test.htm"); I'm wondering why the window is empty. I check the test.htm file created and it's not empty. I also tried Navigate2("file://...../menu.htm") and still empty window was display...
Also, I tried passing it to an existing URL like "http://www.codeproject.com" and there's no problem with it.
I'd like to ask if I miss something there?. Is there's a way that the created html file is the display on the window?
Thanks..

I have re-created another project that had similar functions. It worked correctly.
Please, try to open created HTML files by IE to check whether that files display well or not.
Contact me if you want to get a working sample project by email.

Thanks for the reply.
I already try to open the created HTML files by IE and also by Mozilla and it display fine. That's why I'm wondering how I can deal with it.
Please... please... help me with this matter.

Is it possible to view the Japanese text in the dialog box editor itself?
|
|
|
|
|
Try to use APPWZJPN.DLL for your project. Menubars, Dialogs, etc. will display in Japanase. If APPWZJPN.DLL is not existed in your "Microsoft Visual Studio\Common\MSDev98\Bin\IDE" folder, copy it from the CD installer of Visual C++. Or just google it and put it on that folder.
Hope it will helps.

Ok. I will try in that way.

Hello All,
How can I give mulitlingual support to my dialogs?
Thank you.

In my case I found that the best solution was the creation of several XML files (one for each language needed) with all the text needed referenced by a unique id and call each text from within the code like: GetMessage(int id).
then, the only hardcoded part is the id of the message, not the whole string.

Hi,
Is there a free downloadable C++ Class design tool.
I am not looking a complex tool like UML tools. Simple tool which can represent the class and the properties in form of a diagram..
Thanks,

What about MS Visio? It's not free but it comes with Office packages and it meets your goals.

This message will not be sent, when i use SetItemText to change the item
text.
I want the parent to be notified when SetItemText is called, because I don't call SetItemText in CListCtrl's parent.

Look for LVN_ITEMCHANGED or LVN_ITEMCHANGING message

I tried, but it didn't work.
There is no LVN_ITEMCHANGED or LVN_ITEMCHANGING when SetItemText is called.

Hi,
the CListCtrl is in a dialog?
Have you create a dialog member function for this CListCtrl (e.g. OnItemchangedMyCListCtrl)? (This is OK at my projects)
Or have you the dialog member function "PreTranslateMessage" and look for the LVN_ITEMCHANGED message?
Greetings

Maybe I can not express myself.I mean that I want to develop a ActiveX control container.
Firstly, my document CxxDoc is derived from COleDocument,and the constructor as following:
CxxDoc::CxxDoc()
{
// EnableCompoundFile();
// ^^^^^^^^^^^^^^^^^^^^^^^^^^I need a flat (uncompound) file.
...
}
Is it OK????
Secondly,my client item is CxxClientItem
class CxxClientItem : public COleClientItem
The WriteItem and ReadItem function (copied from the sample program of ActiceX control test container in Visual C++) as follows. They can work correctly in compound document. Please tell me how to change them from compound document to flat(uncompound) document.
