How to change size of a win32 toolbar after TB_DELETEBUTTON

ioctl5112-Sep-07 0:13

12-Sep-07 0:13

Hello, i have a toolbar with small icon buttons in. When i delete a button by sending a TB_DELETEBUTTON to it, it dosn't resize automatically. And since the buttons have a fixed size, there is an empty spot in the toobar, where i want it to automatically resize to fit the number of buttons.

How do i do this? Iv tried sending TB_AUTOSIZE to the toolbar, but nothing happens. Must i manually use TB_GETMETRICS and TB_SETMETRICS to calculate the new size of the toolbar?

Thanks

I am doing printing on two types of printer e.g EPSON StYLUS C82 & HP Deskjet 5700.When printing using HP,i have displayed two Text one after other with some coordinates passed to it.Text are displayed one after other with some GAP.But when i print using EPSON ,Text are displayed one after other with Larger GAP.How this problem could be soved.Example code of this is:

pDC->ExtTextOut(XCoOrdinate,YCoOrdinate+LINEGAP_Y,ETO_OPAQUE ,NULL, "Date",NULL);
XCoOrdinate+=ParamHeadingRectWidthPrint;
pDC->ExtTextOut(XCoOrdinate,YCoOrdinate,ETO_OPAQUE ,NULL, "Time",NULL);

Thanks & regards,

You will need to use NON DEVICE DEPENDANT UNITS. I had some problems like that printing with the same mark but different models.

I coded it in that way:

void CMyView::OnPrint(CDC* pDC, CPrintInfo* pInfo) 
{	
	CMyDoc* pDoc = GetDocument ();
	ASSERT_VALID (pDoc);
	// Setting printing parameters
	pDC->SetMapMode (MM_LOMETRIC);
	
	double dLeftOffset=200-(pDC->GetDeviceCaps(PHYSICALOFFSETX)*254.0)/pDC->GetDeviceCaps(LOGPIXELSX);
	double dTopOffset=200-(pDC->GetDeviceCaps (PHYSICALOFFSETY)*254.0)/pDC->GetDeviceCaps (LOGPIXELSY);
	double dRightMargin=1950-(pDC->GetDeviceCaps (PHYSICALOFFSETX)*254.0)/pDC->GetDeviceCaps(LOGPIXELSX);
	double dBottomMargin=2770-(pDC->GetDeviceCaps (PHYSICALOFFSETY)*254.0)/pDC->GetDeviceCaps(LOGPIXELSY);

	pInfo->m_rectDraw.left += (int) dLeftOffset;
	pInfo->m_rectDraw.top += (int) dTopOffset;
	pInfo->m_rectDraw.right = (int) dRightMargin;
	pInfo->m_rectDraw.bottom = (int) dBottomMargin;

//...

then to print images... I used the ::StretchDIBits (...) function, and to print text the pDC->TextOut (...) function. But using coordinates like

pInfo->m_rectDraw.left + XXX;
pInfo->m_rectDraw.top - XXX;

and so on.

Hope it helps

Greetings.

Thank u for u help.I am facing with another problem in same thing.While printing font changes for different printer.I have created font using:

int nHorz = pDC->GetDeviceCaps(LOGPIXELSX);
CFont fnTimes;
int FontPrinterWeldData = (EUROPEANWELDDATAFONT*nHorz)/PIXPERINCH;//..where //PIXPERINCH=150,
//EUROPEANWELDDATAFONT=18

fnTimes.CreateFont(FontPrinterWeldData , 0, 0, 0, FW_NORMAL ,FALSE, FALSE, FALSE, ANSI_CHARSET, OUT_DEFAULT_PRECIS,CLIP_DEFAULT_PRECIS,DEFAULT_QUALITY, FF_DONTCARE, _T("Courier New"));

I can't understand why font change for printer.

Thanks & regards,

I guess it is because not all printers have the same PixelsPerInch, it depends on printers, properties of actuall printing job (optimal, low quality...) and other factors

I use the font as follows:

CFont fontLabels;
fontLabels.CreatePointFont (80, "MS Sans Serif", pDC);
CFont fontInfo;
fontInfo.CreatePointFont (140, "MS Sans Serif", pDC);

From MSDN help:
BOOL CreatePointFont( int nPointSize, LPCTSTR lpszFaceName, CDC* pDC = NULL );

This function provides a simple way to create a font of a specified typeface and point size. It automatically converts the height in nPointSize to logical units using the CDC object pointed to by pDC.

When you finish with the CFont object created by the CreatePointFont function, first select the font out of the device context, then delete the CFont object.

.........

It works good for me. I have tested it with 5 different printers (in high and low quality) and a plotter without problems. I don't want to say it will never have problems, but i think is one of the best options.

The fact is to use a standard font that ALWAYS goes with windows like arial, ms sans sherif, times new roman and so on... using CreatePointFont

Have you tried a more WYSIWYG approach? Try using the MM_ANISOTROPIC mapping mode as it makes it easier to match your view and print output using the same OnDraw code.

Here's a quick sample to plop into a new CScrollView doc/view app to see if the results are consistent on your printers. Keep in mind that it's more important to preserve aspect ratio, keeping everything proportional, and ensuring no drawing code falls outside the printable area. You will find small variances in the metric accuracy on all printers so focus more on the relative placement and you'll suffer less print anxiety.

The same way you would any other piece of text. Most controls utilize SetWindowText() for this.

how to find the list of activex controls

in my vc++ 6.0 project, i want to know the list of activex controls used.
is it possible.kindly raise your views on this point.
why i wanted this?
long ago(1.5 years) i developed one project and used some activex controls in that.
now i have opened that project in some other system and i am getting the error regarding the missing activex controls.
i can trace them back if i can know the list of activex controls i have used.
thanks in advance.

Open the .rc file of your project in any text editor ex notepad.
search for some key similar to "{########-####-####-####-############}" where # is 0-9 or A-Z
Open Registry using Regedit and Search this key in your registry.
If this key does not exist, then this is the com component that is missing.
You can search the component on your old machine using same technique.

thanks for your reply.
the idea of searching for the components using classid is appreaciable.
but i was looking if somewhere the classnames(activex control names) are specified in the project.
because even in my old machine they maynot be registered.
kindly look into this.
thank you.

You can check the wrapper class for each ocx control. Sometimes it may help you find out which control does it point to.

First create the dialog box.On the dialog box create the edit box and create the group box,on the group box keep the unlimited radio buttons and create the buttons inforent of each radio button.
create 3 buttons on the dialog box of which
1=assign button
2=ok button
3=cancle button

First user should use assign button and after than cursor should move on edit box.Whatever you write on edit box each should go to respective radio buttons.If it is allready assign numbers are there,they should reflect on the radio buttons.
When the users work is complete the cursor should come on ok button.Agian it goes to cancel button.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
