Hi everyone,
it's possible to set on creation a specific RGB-Value as Backgroundcolor for a CFormView.
Is it also possible to change the backgroundcolor at runtime? for example by clicking a button?
If i change the brush like this m_bgrBrush.CreateSolidBrush(RGB(255,255,255)); it crashes during the click-event
Thanks

You can use of a variable on m_bgrBrush.CreateSolidBrush(yourcolor);

That's the problem, it will not work.
If i change a variable that's used in OnCtlColor it doesn't work also 
HBRUSH FEinstellungenView::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CFormView::OnCtlColor(pDC, pWnd, nCtlColor);
if((nCtlColor == CTLCOLOR_STATIC) || (nCtlColor == CTLCOLOR_DLG) )
{
// Ändert
pDC->SetBkColor(MyColor); // MyColor is a DWORD that i change in the click-event MyColor = RGB(255,255,255)
return (HBRUSH) m_bgrBrush;
}
return hbr;
}
Thanks

You get an error because you created CBrush prevoius CreateSolidBrush.You can declare a variable for color like:COLORREF color; color=RGB(0,0,100);
|
|
|
|
|
BOOL FEinstellungenView::OnEraseBkgnd(CDC* pDC)
{
CRect rcClient;
GetClientRect( &rcClient );
pDC->FillRect(rcClient, &CBrush(*MyColor)); // On the click i change the MyColor Value
return TRUE;
}
Thats the easiest way i think
I found it after a long Google Research
Thanks nevertheless

Or you can use pDC->FillRect(rcClient, &CBrush(MyColor));

Hi,
try this, it worked very well by me. hope it helps
HBRUSH CPickOColorDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
switch( nCtlColor )
{
case CTLCOLOR_BTN:
break;
case CTLCOLOR_STATIC: //if you have some static text
pDC->SetBkMode( TRANSPARENT );
return static_cast<hbrush>( m_brBack.GetSafeHandle() );
break;
case CTLCOLOR_DLG: // for the form view / dialog view
return static_cast<hbrush>( m_brBack.GetSafeHandle() );
break;
case CTLCOLOR_EDIT:
break;
}
return hbr;
}
void CPickOColorDlg::OnBnClickedButtonColor()
{
m_brBack.DeleteObject();
m_brBack.CreateSolidBrush(RGB(255,0,0));//red
Invalidate(TRUE);
}

We are sorry for the inconvenience.".Can any one knows why this error comes and how can we rectify it.
Thanks.

Did you try debugging and find where exactly the error occurs? And can you post the code here?
|
|
|
|
|
I have written the code like this to open the document files when button is pressed,
static TCHAR BASED_CODE szFilter[] = "Windows Setup file (*.pdf;*.xml)|*.pdf;*.xml||";
CFileDialog oFileDlg(TRUE,"pdf","",OFN_FILEMUSTEXIST|OFN_NOCHANGEDIR, szFilter);
oFileDlg.m_ofn.lpstrTitle = "Select the Installable Application";
if(oFileDlg.DoModal() == IDOK)
{
m_install.m_strSetup = oFileDlg.GetPathName();
GetDlgItem(IDC_SETUP)->SetWindowText(m_install.m_strSetup);
}
|
|
|
|
|
This code is alright. Did you not try debugging? What is m_install? Comment the last line and see if it works.
|
|
|
|
|
when i dedugged the error is coming after that line.It is working in one system and but not in the other.
Thanks.

Which line? Am I supposed to guess it?

Check out the dependencies.

I asked you what is m_install. Is that a CString or char* or what? Did you try using a CString variable there, instead of a member variable?
|
|
|
|
|
After m_install.m_strSetup = oFileDlg.GetPathName();.
m_install is a Cstring variable of another class.Now i hav e defined a cString variable in the same class.

<br />
CString str;<br />
<br />
static TCHAR BASED_CODE szFilter[] = "Windows Setup file (*.pdf;*.xml)|*.pdf;*.xml||";<br />
<br />
CFileDialog oFileDlg(TRUE,"pdf","",OFN_FILEMUSTEXIST|OFN_NOCHANGEDIR, szFilter);<br />
oFileDlg.m_ofn.lpstrTitle = "Select the Installable Application";<br />
<br />
if(oFileDlg.DoModal() == IDOK)<br />
{<br />
str = oFileDlg.GetPathName();<br />
AfxMessageBox(str);<br />
}<br />
Do you get the path displayed properly? Does the window crash after that?
|

Now I remember, I already answered you previously. I asked you to use your debugger to provide us more information. Did you follow that advice ? Where does the code crash exactly ? What is the value returned by GetDlgItem, are you sure you don't access an NULL pointer ?
Man, I won't say it enough time: you have to learn how to use your debugger !It doesn't take a lot of time to understand how it work (for basic debugging), but this will save you hours of time (your problem could already been solved now).

The only answer we can give you is that you did something wrong in your program. This can happens for a million of different reasons, so without more information, you'll not get a lot of answers.
First of all: a thing that you REALLY need to do is to learn to use your debugger. You cannot imagine how faster it is to solve a problem than posting a message on a forum. Press F5 to start your debugger, this will allow you to narrow the problem a little bit more. Then, you can set breakpoints in your program with F9 and check the value of your variables.
I cannot imagine developping programs without using a debugger, it's like repairing your car without using any tools

The application is working in my system.But when i run it on the other system it is not coming.I have debugged the application.The error comes after the line of getting path name.
Thanks.

It seems this code it good maybe your problem after IDOK did you use of debugger
|
|
|
|
|
|
so this problem isnt of CFileDialog.did you use of breakpoint and what is m_install and IDC_SETUP is valid
<br />
m_install.m_strSetup = oFileDlg.GetPathName();<br />
GetDlgItem(IDC_SETUP)->SetWindowText(m_install.m_strSetup);<br />
|
|

m_install is a CString variable of another class.Now i have defined the variable in the same class and i have removed the edit box which displays the path and the code for that line.Now it is working.Thanks
|
|
|
|
