I think your File Handle is NULL. Let me know if you are doing any file operation in your application. If yes, then verify the Handle validity.

For information on how your program can cause an assertion failure, see the visual c++ doc on asserts.
I like to see you test.cpp,tell me it is Console application or any MFC based application.

You attempted to use CFile::Seek() with an invalid file handle.

Using VC6/MFC
I've coded a wizard dialog, and am trying to get the OnWizardNext function in the wizard pages to perform as described in MSDN. According to the documentation:
- returning -1 tells the wizard dialog not to change pages
- returning 0 tells the wizard dialog to move to the next page in the sequence
- returning any other (positive) value tells the dialog to move to page in the chain indicated by the return value.
Returning -1 and 0 works fine, but returning any other value acts as if I'm returning -1. I've verified that the value being return is the value I'm expecting, and I'm not calling the base class' version of the function.
Can anybody provide any hints as to what I might be doing wrong?

"0 to automatically advance to the next page; 1 to prevent the page from changing. To jump to a page other than the next one, return the identifier of the dialog to be displayed."
Are you passing the ID, or the index of the page?
You could always call SetActivePage in the OnWizardNext if neither the resource ID or page index works...
 Pssst. You see that little light on your monitor? That's actually a government installed spy camera. Smile and wave to big brother!

the other value is the resource ID of the next dialog you want to display.
I've had the same problem a couple weeks ago ... bloody MSDN ...

Hello, I would like to have the text of the static control printed in red (just for one of them on my dialog). Is it possible to do that without subclassing the control ?
Thanks
|
|
|
|
|
1) Assign an ID to the static control you want to have the red text. (i.e. IDC_REDTEXT_STATIC)
2) Add a handler for OnCtlColor in your dialog.
3) Check for the control ID in OnCtlColor, and update the device context text color to red:
<br />
HBRUSH CMyDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)<br />
{<br />
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);<br />
<br />
if (pWnd->GetDlgCtrlID() == IDC_REDTEXT_STATIC)<br />
pDC->SetTextColor(RGB(255,0,0));<br />
<br />
return hbr;<br />
}<br />
Pssst. You see that little light on your monitor? That's actually a government installed spy camera. Smile and wave to big brother!

Hello!
I have got the following problem!
Ich have written a Dll for a Socket Connection. This Dll call a callback function when it receives a Msg over the net.
The function which is called from the dll is a global function in my Testapplication. The global function calls my receive function which only copys the msg in two Membervariablen from the Dialog. These Membervariablen are undefined (Debug shows: ???) and the program crashs.
Global receive function
void gReceiveMsg(CMsg *pMsg)
{
((CSocketTesterApp*)AfxGetApp())->CallbackReceiveMsg(pMsg);
}
function in my application (the values are received correct )
void CSocketTesterApp::CallbackReceiveMsg(CMsg *pMsg)
{
CString sVar = "";
double nVal =0;
pMsg->GetData(&sVar,&nVal);
((CSocketTesterDlg*)AfxGetMainWnd())->ReceiveMsg(sVar,nVal);
}
receive function in my Dialog
void CSocketTesterDlg::ReceiveMsg(CString sVariable, double nValue)
{
m_sRecVariable = sVariable;
m_nRecValue = nValue;
UpdateData(FALSE);
}
The Program crashs after the assignment to the membervariable.
I hope someone can help me!!!

I’m using a CTreeCtrl to display an hierarch structure of a database. Is it possible to allow the user to select multiple items using for e.g. “shift” and “ctrl”?
Thanks / Anders

I don't think it's in the standard CTreeCtrl behaviour; google for CMultiTree it handles multiselection.

hi!
i wanted to add multiple items toa list box, and tried using LBS_MULTIPLELSEL. Yet only one item is added. how do i do it? -V.G?
|

hi,
If u are doing this using Visual C++/MFC ,It is very easy to set Multiple selection to the ListBox.
Go the properties of the added List Box change the selection to 'Multiple'.
That's all.

Like this:
m_listbox.AddString("Item 1");
m_listbox.AddString("Item 2");
...
m_listbox.AddString("Item N");

How many times are you calling this function?
