Re: CStatic embedded to a Progress Dialog gets disapeared when the window is resized

16-Jun-08 21:02

Hi,

I have a Progressdialog on the center of which I have placed a CStatic control to display the Progress percentage.But when the dialog is resized the CStatic Control gets disapeared and so the percentage.

Can anybody help me out of it.

Thanks and Regards,

Can you show your code?

Where/how did you create the static control?

Hi,

Actually the ProgressDialog is a subclassed from CProgressCtrl and the CStatic is placed on the top of it. Now When the progressbar proceeds it displays the progress percentage on the CStatic Control. During this process if the user resizes the window bu maximizing or restoring it, the CStatic gets disapeared.
I am unable to show the code for its bulkiness.
If you can help me otherwise, I would be really be very very thankful.
I had also made one sample application but the issue is not getting reproduced over there.

Thanks and REgards,

At design time or run time?

Well, Run Time.
I have achieved Transparency of the CStatic now.
This is what my sample application has done

HBRUSH CStaticTestDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

// TODO: Change any attributes of the DC here

if(nCtlColor == CTLCOLOR_STATIC)
{
hbr = (HBRUSH)::GetStockObject(NULL_BRUSH);
pDC->SetBkMode(TRANSPARENT);
}
// TODO: Return a different brush if the default is not desired
return hbr;
}

And my ButtonClick handler is :

void CStaticTestDlg::OnBnClickedButton1()
{
TCHAR szBuff[200];
int i=0;
m_Progress.SetRange(0,100);
m_Progress.SetPos(0);
m_Progress.SetStep(1);
for(m_nNum=0;m_nNum<100;m_nNum++)
{
Sleep(1000);
m_Progress.StepIt();
_stprintf(szBuff, _T("%d"),m_nNum);
m_Static.SetWindowText( szBuff);

}
// TODO: Add your control notification handler code here
}

But Now the problem is that when the szBuff gets overwritten.
Can you please help me achieve removing overwriting.
If I use a WHITE_BRUSH in the OnCtlColor() then everything is fine only the CStatic remains no more transparent.
Plz Help!!

Thanks and Regards,

OnCtlColor() is not being used for anything. Comment it out and note the result.

Hi,

Thanks for the reply.
But, that's not the case. Please note my requirement first.
My Requirement is:
1. To make the CStatic Transparent with respect to the CProgressCtrl. The Scenerio is that CStatic is placed on the CProgressCtrl.
2. The Progress % should be displayed on the CStatic without overwriting the previous no. I.e. '1' should not get overwritten on '0' and so on.

OnCtlColor() makes the CStatic Transparent. So your statement is not valid here. The only problem is that only if I use any other brush than the HOLLOW_BRUSH/NULL_BRUSH...it works fine but Transparency is getting lost.

However I want to achieve both.

Thanks

Are you wanting something like this? If so, don't use two controls; one will suffice.

Is it posible to use the hotkeys CTRL-R, CTRL-H for doing some actions in an IE plug-in?

Thanks a lot. That was what I exactly wanted.
Thank You very much.

I am working at an Internet Explorer plug-in. (afp viewer plug-in)
I want to use the shortcut keys CTRL-R and CTRL-H to do some actions (reset view,...).
The problem is these keys are shortcuts for IE.
Is there a way to get the keyboard messages before they go to IE?
Or should I use other shorcuts?

Why do you want to mess up with those predefined shortcut keys? Using some key combinations of your own will be a wise idea. But that's just my opinion.

My project manager wants to use these keys.
I suggested using other keys...

It is your duty to explain him that the user will be annoyed if your application overrides predefined shortcut keys. Secondly, explain him the complexities involved in doing it. It is not impossible, but it is not worth doing.

Hi all,

1. How to show dialog such a way that it's Bottom-Right corner will at same position of Bottom-Right corner of Screen?
Also to show dialog at Top-Left corner of Screen?

2. How to hide application/dialog at the start of application?
Normally by calling this->ShowWindow(SW_HIDE); application get hidden.
But when I called this->ShowWindow(SW_HIDE); in OnInitDialog() function of dialog, application is still visible. What is the solution?

Do you want to set position of your dialog you can use of WM_SIZE with MoveWindow or SetWindowPos and also on this event you can use of ShowWIndow(SW_HIDE).

But how to get co-ordinates for MoveWindow function call, so that Bottom-Right corners of dialog will match with Bottom-Right corner of Screen.

Also to show dialog at the Top-Left corner of Screen, I made a function call as this->MoveWindow(0,0,Width,Height); but dialog was appearing at the center of Screen.

int nHeight = GetSystemMetrics(SM_CYSCREEN);

And in case if you want to support multiple monitors use SM_CXVIRTUALSCREEN, SM_CYVIRTUALSCREEN constants.
