Associate your control with a control variable using the class wizard. For example you can associate your edit box with c_edit1.

Now give :- c_edit1.SetFocus()

Put this under your WM_INITDIALOG handler

GetDlgItem(IDC_EDIT01)->SetFocus();
return false;

This should work. You said it didn't work for you. That's probably because you forgot to put return false. By default it is return true. You have to change that to return false.

Hmm

Well I just created a dummy dialog based project and added an edit box and a button. I adde this to the button's on-click and no-problems at all. Focus did shift to the edit control.

void CTestDlg::OnButton1() 
{
	GetDlgItem(IDC_EDIT1)->SetFocus();	
	
}

To add to that...
Since you mentioned the OK button I also tried this and no-problems again

void CTestDlg::OnOK() 
{
	// TODO: Add extra validation here
	
//	CDialog::OnOK();
	GetDlgItem(IDC_EDIT1)->SetFocus();
}

Square function?

Chambers4-Nov-01 2:03

Chambers

4-Nov-01 2:03

What is the square function in VC++? I have tried using :

pow(a, 2);

but its ridiculously slow (i need to perform many such calculations), now i`ve just got (a*a) instead (which is crap loads quicker). I just need to know that I`ve gone about it the right way.

Cheers all,
Alan. Big Grin | :-D

The fastest way to calculate the square of a number would be to use the * operator as you have already tried out. When you do a*a that's about the best you can do. Because it translates into the MUL instructions directly.

But if you want to do floating point squaring then I am not sure. Perhaps you could try using logarithms [which involve addtitions and not multiplications] which might speed up things.

In the DOS days I remember how we used to set the compiler/linker options to generate 80x87 code that speeded up the mathematics. I wonder whether there is some such thing for win32 stuff too.

Many thanks Nish. I needed to know that that was the best (quickest) way of going about squaring a variable (integers).

URGENT ODBC and Printing problems

4-Nov-01 0:34

1) I'm writing a program that uses odbc and microsoft access database as source. Is there a way that I can programatically set the information about the database in the ODBC Administrator in the Control Panel? If yes please give me an example.

2) I need to print a specific area of the form(It's a SDI App) and I'm not sure what to do. CRgn or what. How can I specify that region and print it? Also I must show that region in the print preview, but since OnPrint is only function called both for Print and print preview I guess I will need just one code for both things.

thanks,

Deian

WinXP Visual Styles (Themes)

Hello all!

I’m trying to use the new Windows XP Visual Styles API (the themes stuff) to draw a toolbar, but I’m stuck Dead | X|

I’m trying to get the font to draw the buttons but I have no idea of what is a PropId or where to get it from..... and the help of online help helps nothing...... So my question is, what is a PropId and where are they defined?

My code snipped,

HWND m_hWnd;
HDC hDc;
...
HTHEME hThemeToolBar= ::OpenThemeData(m_hWnd, L"TOOLBAR");
LOGFONT log;

// the propid (?) that I’ve copied from the TmSchema.h file
int iPropId= TMT_CAPTIONFONT; // What value to place here? I’ve also tried to make a for with all possible values but only one (PropId 12) returned a valid hr result Frown | :(

and that one with a strange LONGFONT result…..
HRESULT hr= ::GetThemeFont(hThemeToolBar, hDc, TP_BUTTON, TS_NORMAL, iPropId, &log);
...

The error returned has always 0x80070490 (Element not found.)... the PropId 12 is the only one that returned a hr of 0, but I have no idea of what is it.... since the font returned is very strange.... and also with the call to GetThemeFont the Theme handle (hThemeToolBar) becomes invalid!? Confused | :confused:

Anyone can help me with this?

Thanks in advance!

Hi
I am working on a ActiveX project where I want to implement XP Theme onto my controls. While searching www.codeproject.com I came across your posting, and ofcourse without an answer. (infact I could find only yours)

Could you please spare some time of yours? I am also in the same posistion as you, and couldnt find answers regarding this. Did you manage to use GetThemeFont on BUTTON and TOOLBAR ? If so I will be grateful if you could share this with me.

Thanking you and awaiting your response,

Menus aren't windows. If you need a menu handle (HMENU) call GetMenu() and pass it your main window's handle (AfxGetMainWnd() if you're using MFC).

Bitmap Editor for Image Lists

3-Nov-01 17:01

My eyes just will not tolerate using the bitmap editor in visual studio. I would appreciate if anyone can recomend an editor that supports sizing and editing bitmaps for image lists. IE controls for 16 by 16x and increments.

Sorry for not logging in. The system just has not like my Name or address for the last few days.

I'll probably end up solving this before someone replies,but here is my problem:

I have an header that contains an array which contains the default setting for my app. I include the header into my main file, then include it into the cpp file for a class. The h file for the aforementioned class is also included by my main file. When I attempt to compile I recieve several multiply defined symbol errors. If I remove the inclusion from either file, the function that use the settings are unable to compile. If you can make heads or tails of my above statment, more power to you. Thanx.

I`m only a beginner to this kind of stuff but I think you could also try (as an alternative to Christians suggestion) using these statements to go at the top of the header file of the implementation of your class :

#ifndef YOURCLASSNAME_H
#define YOURCLASSNAME_H

You should then be able to #include the header into the .cpp file, and then #include the header anywhere you want. (Just make sure you specify YOURCLASSNAME_H all in capitals, for some reason it won`t work otherwise) Big Grin | :-D

Then you also need a
#endif
in the bottom of the headerfile...

If you only need to compile it in VC, you can get the same effect with a
#pragma once
