Where are you using the icon? You mentioned ShowWindow() so I'm guessing your using it in a window... do you need to diplay it more than once in a window, or are you wanting to diplay it in multiple windows?

I could have created a bitmap file as well, either would have worked. I need to show it multiple times from a single dialog window. Anywhere from 1 to 7 times. Right now I have...

// Dialog Data
	//{{AFX_DATA(CProgressDlg)
		enum { IDD = IDD_PROGRESS_DLG };
		CStatic	m_ctrlCheck1;
		CStatic	m_ctrlCheck2;
		CStatic	m_ctrlCheck3;
		CStatic	m_ctrlCheck4;
		CStatic	m_ctrlCheck5;
		CStatic	m_ctrlCheck6;
		CStatic	m_ctrlCheck7;
	//}}AFX_DATA

I would think this is a waste, since 90% of the time i will only show 3 or 4. My guess is that there is a way to create/show them without creating a variable for each possibility.

Its sounds like you to me like your making one of those nifty progress dialogs that puts checkmarks beside the tasks that have been completed. Have you considered making an owner-drawn static control that can display the checkmark and the task's text? You could then just create the number of them you need dynamically -- and just store their pointers a list.

LoadString and std::string?

Derek Price25-Jul-01 8:42

Hello!

Is there any way to use a std::string with the Windows API method LoadString() without having to use a char* as an intermediate step? For example, something like this:

std::string junk;
LoadString(AfxGetInstanceHandle(),IDS_JUNK_STRING,junk.c_str(),250);

This doesn't compile, but maybe there's a way around it. I'm just not used to mixing STL and C-API's.

Thanks,
Derek

Yes you can.

const int MAX = 250;
std::string junk;
junk.resize(MAX);
LoadString(AfxGetInstanceHandle(), IDS_JUNK_STRING, &junk[0], MAX);

Jam on.

Thanks! It works using a std::vector<char>, but I wasn't sure if it was correct to use the same &junk[0] method for std::string.

Yep, vector and string are the two STL containers with guaranteed contiguous memory.

Actually, Neither string or vector guarantee contiguous memory today. There is a proposal in front of the committee to alter the standard to require contiguous memory for vector, but not for string.

Having said that, it's highly unlikely that anyone will create a string implementation that doesn't use contiguous memory, at least on Win32.

Toolbar in a MDI child frame

I'm writing a MDI application with a toolbar in a child window. I want to chnge the toolbar from flat to non-flat buttons (and back) programatically.

I've already got a function in the CChildFrame class that responds to an message, but everything I try results in failure (in one form or another).

Does anyone know what the secret is?

Hi John,

I just tried with ModifyStyle(TBSTYLE_FLAT, 0) (and vice-versa) and Invalidate() and it seems to work. It's a very simple project though ...
From where are you trying to change the toolbar? (I did it in the MDI child frame)

Well, I think we all need more details to help Smile | :)

Paolo.

I was over-engineering my own attempt at a solution, and was so far into the forest, I couldn't see the trees. Smile | :)

Font color?

I can't figure out how to control the color of text drawn with CDC::TextOut. CFont or LOGFONT don't seem to have a color attribute, and none of the other crazy things I tried worked. Ideas?
thanks,
Jake

what is the numbers range that can be in type long ?

A long is 32bits.

so try 2^31 for a long (1 bit for sign) and 2^32 for an unsigned long

+-2147483648 and 4294967296

there are defined for these. Look for MAX_LONG, MAX_FLOAT etc.

from -2147483648 to 2147483648.

The LONG is a 32-bit signed integer!!!

xor

25-Jul-01 5:39

What this 'xor'?

How do use in this in vc++

Re: xor

Carlos Antollini25-Jul-01 6:02

Carlos Antollini

25-Jul-01 6:02

True xor True => False
True xor False => True
False xor True => True
False xor False => False

For use it you need to use the ^ macro.

^ == Xor

Cheers Big Grin | :-D

Where do I need put this sign^ ? before the number ?

25-Jul-01 8:40

so:
^x;

or so:
x^;

or another ?

Re: Where do I need put this sign^ ? before the number ?

25-Jul-01 8:47

XOR is a binary operator.

z = x ^ y;

if x = 00101101b
and y = 01110111b
then z = 01011010b

Hope this helps.

which function insert to string some parametrs as doing printf(" ",a,b) but not for print.

25-Jul-01 5:38

CSrting str;

I want that str would contain some variables in its string
for example so:
str = (" the price is %d, the nameis: %s", x,s);

Carlos Antollini25-Jul-01 5:46

25-Jul-01 5:46

Use.
CString::Format();

Is like sprinf();

CString str = _T("");
int iVal = 10;
Cstring strName = _T("Carlos");

str.Format("The price is %d, the name is %s", iVal, strName);

Cheers!!!
