add to the editbox a WM_KILLFOCUS handler.

it will be called each time the edit looses focus.

inside the handler, call WM_SETFOCUS...

Thanks for your advice !
I have try the first one, but I should make changes (add message hendler) to every "focusable" object existing in a box (in real life there is more controls than in my sample Smile | :)

). Second one unfortunately doesnt fit my needs...

Now I'm playing with MA_NOACTIVATE (OnMouseActivate), with only partial success...

text to number

Hi,
I have a little problem converting a string to a number.

Situation:
string : "1.555,23"

thousand seperator = "."
decimal seperator = ","

Why doesn't this help?

<br />
lconv* pConv = localeconv();<br />
pConv->decimal_point = ",";<br />
pConv->thousands_sep = ".";<br />

Using the default "C-locale", things get messed up.
How can I make sure it uses the (above) seperators so i get correct conversion?

Best regards,
Jens

text length and CStatic object

Use atoi() or atof().

Use localeconv() to get information about the locale settings. Use setlocale() to set, change, or query some or all of the current program locale information. So are you trying to get or set information? Why aren't you using GetLocaleInfo() and SetLocaleInfo()?

How to know the length (in pixel) of a text string in a CStatic object?
It isn't sure that the current displayed text is the text on interest.

[Seemes that pStatic->GetDC()->GetOutputTextExtent("bye bye") isn't the right way] Frown | :(

thanks

What about CDC::GetTextExtent()?

I get the same values in boh cases,
but far from the real length! Frown | :(

Why do you need to know the width of a string in pixels?

I have a dynamic dialog, and sometimes the text is too large!
So, I was thinking to resize it, but I need to know the text length!
Any tips?
thanks.

David Crow8-Mar-06 5:23

So if you have text that is 1025 pixels wide on a 1024x768 monitor, will the dialog therefore go off the edge of the screen?

The problem is that (for example)
my Dialog width is 150 pxl,
it contains a CStatic (width=100)

But sometimes the text needs 120 pxl so te text is cutted (at the end). D'Oh! | :doh:

My solution is to redraw the Dialog where:
CStatic has 130 pxl (width) and Dialog 160.

I have the code ready for everyrhing, and now I need only to know the string length. Confused | :confused:

You might have to use CDC::GetOutputTextMetrics() along with GetTextExtentExPoint(). Add size.cx and tm.tmAveCharWidth together to see what that produces. Don't forget to select the static control's font into the DC before taking any measurements.

disappearing CPropertyPage's

Just a suggestion, you can wrap text in a static control.

I have a VC++ MFC application in VS 2005. In this application I use CPropertySheet's in several locations. The program works fine for a while, but at some point the CPropertySheet's stop working, in such a way that when I click on a CPropertyPage tab, the tab for that sheet disappears completely or the controls on that CPropertyPage are all invisible. I'm guessing that I'm running out of resources, handles, memory, etc.

Can somebody advise me on what to look for in the way of resources or memory, so that I can circumvent this problem? Also, what utilities would be useful to diagnose the problem? At the very least, I'd like to have the program detect the problem and warn the user to save their results.

Thanks

using CIPAddressCtrl::GetAddress

hi
i have a small app im putting together. i have put in a "IP Address" box and have a button then when click will store the ip address.

from what i can see you use CIPAddressCtrl::GetAddress to get this address, what am i doing wrong below? I am using vc++6.

BYTE nField0, nField1, nField2, nField3;
int rc = CIPAddressCtrl::GetAddress(nField0, nField1, nField2, nField3);

should that not put the address into each one of those byte fields?

i am getting an error as below..
error C2352: 'CIPAddressCtrl::GetAddress' : illegal call of non-static member function.
afxcmn.h(1112) : see declaration of 'GetAddress'

please help
thanks

GetAddress() is not a static member. It must be called in the context of a CIPAddressCtrl object. Use ClassWizard to associate the control with a CIPAddressCtrl object.

Which part? Use Ctrl+W to open ClassWizard. Click the Member Variables tab. Select the desired control and click the Add Variable... button.
