I cannot figure out the syntax of passing CArray pointer to a function.
Can anybody point me to a source of info?
Thanks

The * goes after the type name (doesn't matter if it's a template class or not, the rule is the same):
CArray<double,double*>*

Hello,

In addition to what Micheal Dunn said, typedefs make your life more easy when you use templates extensively:

typedef CArray<double, double> CArrayDouble;
CArrayDouble* pArrayDouble = new CArrayDouble();

Hope this helps. Big Grin | :-D

How to add Color's to CEdit box text contents

Hey Friend

I have a dialog based MFC application with a Edit box. User can input TCL scripts into this Edit box. I want to add a feature in this, by which if a User types in a TCL script line starting with "#", then the entire line should change its color to Green. Because a "#" symbol in TCL is a comment symbol. I used OnChar() function to get the User input character, and i can recieve each character from key board.

The block for me in now is how to change the color of a character and then display it in Edit box. Can anyone please help me?

This is the kind of stuff rich edit controls can do. See CRichEditCtrl::SetSelectionCharFormat() and the like.

I have already added the Edit box in my app, and added many functionalitites. If i remove the Edit box now and replace it by RichEdit, will it cause any problems?

Is there any simple sample application which shows how this can be done in RichEdit?

It should not cause any problems. You just have to make sure you set up the rich edit control properly. Call AfxInitRichEdit2() in your app's InitInstance(), and then call CRichEditCtrl::SetEventMask() so the control sends the messages you want to handle.

You could look here[^] for examples, there may even be one that does exactly what you need.

I would suggest you to use control subclassing , just derive new CEditEx class from CEdit , and add SetTextColor method to it.

[CEditEx.cpp]

...
ON_WM_CTLCOLOR_REFLECT()
...
HBRUSH CEditEx::CtlColor(CDC* pDC, UINT nCtlColor)
{
	HBRUSH hbr;
	hbr = (HBRUSH)m_brBrush;  
   	pDC->SetTextColor(m_clrTextColor);  
 	return hbr;
}
...
void CEditEx::SetTextColor(COLORREF clrTextColor)
{
m_clrTextColor = clrTextColor;
Invalidate();
}

then simply override the WM_CHAR message handler of your Dialog
and use the m_editEx.SetTextColor(RGB(0,128,0)) method where needed.

Thanks for you reply.

I tried the way you have sugested. But SetTextColor will set the GREEN color to entire text in Edit box. Rather than doing to one single line.
Any other way of setting to single lines?

VC 6.0 and latest Platform SDK

Hi!

After reinstalling my PC I downloaded the latest SDK (I used the "August 2002"-SDK before), installed it and set the directories to the SDK. When I try to compile my applications I get several errors, e.g. CWnd::KillTimer() does not exist. Has anybody the same problems? Or do you have any source for the "August 2002"-SDK (which worked quite well for me).

Ciao,
Alex

Its even worse. The new dll symbols are incompatible so you can not even debug your applications...

The same is true for the latest direct draw sdk.

February 2003 is the last PSDK that works with VC6 - I haven't checked the SDK Update site in a while, but it might still be there.

Yes, as always, Mike is correct. However, the CD is labeled (Windows 2003 Server). I am running VC 6.0 on XP and since I installed this PSDK I have problems with MFC assertions. In about 50% of the time when assertion fails XP gets into the act and wants to send "serious problem " message to MS and VC does not stop properly. Needless to say - it makes development harder.
Happy festivus to all.

Is there a simple way of checking to see if an external application, say Microsoft Word, is already running before creating a new process via CreateProcess? Thanks!

You can use FindWindow command (win32 api).
