Re: How to display Russian characters on a non-unicode dialog?

29-Apr-09 4:40

There are some library functions that don't have a unicode build and we don't want to spend money buying in new libraries.

I think it should be possible; the fonts contain the characters in different code pages so I would think someone has done it in the past.

Create a LOGFONT object and set the "lfCharSet = RUSSIAN_CHARSET;" Then create a CFont object ,after that use CreateFontIndirect with the LOGFONT object.Then set this font as EditField font.I think this will help.

///Creating LOGFONT
LOGFONT lf 
lf.lfHeight = 15;                      
strcpy(lf.lfFaceName, "Arial");
lf.lfCharSet = RUSSIAN_CHARSET; 

//CFont
CFont myFont;
myFont.CreateFontIndirect( & lf ); 

//Setting CFont to your EditField    
yourEditField.SetFont( myFont );

No, tried that, doesn't work. It seems that all controls ignore the charset unless the dialog language is set to Russian. When it IS set to Russian, static text controls are displayed using the Russian character set but edit fields are not. Updates to the text in static controls is not displayed using the Russian character set either.

Switching between tabs??

Hi,
i try to switch between tabs in a tab control, i mean, if i have more tabs, how to "get back to tab Index 0" programmaticaly??

Let say the tab with index 3 have a current focus and is showed, by click on button i want to set tab with index 0 as current selected tab??
All my trys before are without any results, because, the controls from a previous showed tab are visible if i go with the mouse over the tab??
This is the simple code:

<br />
void CMyDialog::OnClickChacheTab()<br />
{	<br />
	// m_cTabAll is a CTabCtrl that have many tabs inside:<br />
	m_cTabAll.SetCurFocus(0);<br />
	m_cTabAll.SetCurSel(0);<br />
	m_cTabAll.RedrawWindow();<br />
}<br />

But this take no effects Frown | :(

Does any one can help me here??
Thanks

It sounds like the SetCurSel IS working in that the tab is changing. It depends how you are displaying the controls "inside" the various tabs. Tabs are dumb - they don't know what you're displaying in each tab or even know that there's anything there. It's up to you to hide/display the "contents" of each tab. I usually use a dialog for the contents of each tab and then process the NM_CLICK message to show or hide each dialog.

Hi,
can you show me how to process NM_CLICK message with sample, this is my idea too but dont know how to do this Frown | :(

$Shucks | :-\$ Unsure | :~

Do you mean this message that is from the msdn:

<br />
lResult = SendMessage(      // returns LRESULT in lResult     <br />
(HWND) hWndControl,      // handle to destination control     <br />
(UINT) WM_NOTIFY,      // message ID     <br />
(WPARAM) wParam,      // = (WPARAM) (int) idCtrl;    <br />
(LPARAM) lParam      // = (LPARAM) (LPNMHDR) pnmh; <br />
);  <br />

regards

Yes, WM_NOTIFY/NM_CLICK is sent when the tab selection is changed. You can set a function to pick it up by adding
ON_NOTIFY(NM_CLICK, <tab control="" id="">, <function name="">)
to the message map.

Where your function is defined as -
void <class>::<function name="">(NMHDR* pNMHdr, LRESULT* pResult)

That's the one that will work. I've used it in my code successfully. However, I don't think it will fire your TCN_SELCHANGE handler - you'll need to do that yourself.

The structure I've used in the past is something like this:

MyDlg::OnTabChangedHandler(arguments)
{
   ChangeTab(tab.GetCurSel());
}

void MyDlg::ChangeTab(int tab)
{
   Do stuff
   tab.SetCurSel(tab);
}

MyDlg::SomeButtonClickedHandler()
{
   ChangeTab(0);
}

so - move the 'on tab changed' actions to a separate routine that you can call from other places.

Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

I suppose you must be creating dialogs on each of the tab pages to place your controls.

If that is the case then use the following code to programatically switch to a tab page: ( else just let me know more details. )

void CMyDialog::ShowPage( int nPage )
{
//you need to hide the current dialog.
m_dlgArray[m_tabCurrent]->ShowWindow(SW_HIDE);

//switch the tab.
m_cTabAll.SetCurFocus(nPage);
m_cTabAll.SetCurSel(nPage);

//show the new dialog.
m_dlgArray[nPage]->ShowWindow(SW_SHOW);
m_dlgArray[nPage]->SetFocus();
}

For lack of a better response, your question really makes no sense. If you want to access a file in the current directory, use ".\\somefile" notation. If you want to access a file in the parent directory, use "..\\somefile" notation. If you want to access a file in a subdirectory of the current directory, use ".\\subdir\\somefile" notation.

If that's not what you're after, blame it on my lack of understanding your request.

Hello Davitor,

You can use function - PathFileExists()[^].

Also look at GetFileAttributes() (Which I used just yesterday!)

(One problem with FileExists() is that it returns true for both files and directories.)

hi every one

I create a static library with visual c++ 6.0 App wizard.
I create a new generic class and declared my variables in its header file.
Then I initialized my variables in class constructor.

I want to use it in a new dialog based project, so I add related header file and write my library name in linker tab at project setting.

I create one object of this class in my function, But at the end of function when application exits from function occurs an exception.
I can't handle this exception.

Note : when I comment initialized this exception don’t happen.
Please help me
