Also reading through a 700+ pages in books isn't very efficient if I don't know exactly what I am looking for.
Then try this:
"To avoid asking a programming question in the lounge, it is obvious to me I am missing something in my attempts at handling forms in Visual C++. I posted without getting help here[^] as a reference, but now I am coming looking for what I need to fill in my gaps. I need a tutorial to help me since I am missing some basics, I have googled, I have searched MSDN, but if I don't know what I am looking for how can I find it?
I have .... and .... and .... but it still doesn't help. I don't want to waste my money on yet another book unless it will fill in the basics I am missing. Can anyone recommend a good starting book for doing Visual C++ forms/GUI design and building, please?"
as for the ... for Dummies books.... don't buy them. A) it is self-insulting B) there are far better intro tutorials. You can ask without breaking the rules.

actually, all I did was change your words from "tell me the answer" to "tell me where to find the answer for myself". You said you knew you were missing something small (basics) you said you had books and tried searching but they weren't helping.... All I did was paraphrase you.

"I'm posting it here because I didn't get an answer elsewhere" is disrespectful. If everyone says "I know this is a programming question, but" then the lounge will turn into the local dumping ground for the impatient or lazy.
Moved to the C++ forum.

Sorry for being disrespectful. It was not my intent.

I'm trying to create an activex project with 2 controls. The first is the primary control. The second loads some data and the idea behind it is to call a couple of methods within the first to set some features.
The idea behind this is so if there are multiple instances of the main control each one created doesn't have to load the data as that seems less than optimum for performance.
I tried creating a method within the secondary control which has a parameter defined as the first controls class. It compiled ok but when utilizing the two controls calling that method with the primary control as the first parameter doesn't work.
I'm guessing this is because the class isn't actually the control. My question is it possible to pass a control as a parameter in a method.
If so how do I do it?
Thanks

Hey everyone:
I'd like to kill the scrollbar that appears on my screensaver window when I'm using http://www.codeproject.com/com/cwebpage.asp. I try calling ShowScrollBar(hWnd, SB_BOTH, false); for the hWnd to the screensaver with no results.... any idea why?
Thanks!

Hello,
I am having a proglem with "First-chance exception" when displaying a CFileDialog...
Here is the code I am using to display the dialog.
void CExcludeDlg::OnBnClickedBImport()
{
UpdateData(TRUE);
static char BASED_CODE szFilter[] = _T("Text File (*.txt)|*.txt||");
CFileDialog m_ldFile(TRUE, _T(".txt"), NULL, OFN_HIDEREADONLY, szFilter);
if (m_ldFile.DoModal() == IDOK)
{
CWaitCursor c;
CString strFilePath = m_ldFile.GetPathName(),
strLine = _T("");
CStdioFile file(strFilePath, CFile::modeRead | CFile::shareDenyNone);
while(file.ReadString(strLine))
{
BOOL bFound = FALSE;
strLine.Trim();
POSITION pos = m_strStringList.GetHeadPosition();
while(pos)
{
if(!strLine.CompareNoCase(m_strStringList.GetAt(pos)))
bFound = TRUE;
m_strStringList.GetNext(pos);
}
if(!bFound)
m_strStringList.AddTail(strLine);
}
m_strList.Empty();
POSITION pos = m_strStringList.GetHeadPosition();
while(pos)
{
m_strList += (m_strStringList.GetAt(pos) + _T("\r\n"));
m_strStringList.GetNext(pos);
}
m_strStatus.Format(_T("Count: %d"), m_strStringList.GetCount());
}
UpdateData(FALSE);
}
Here is the error in debug mode.
First-chance exception at 0x7ca51406 in SiteConsole.exe: 0xC0000005: Access violation reading location 0x016d49c8.
Unhandled exception at 0x7ca51406 in SiteConsole.exe: 0xC0000005: Access violation reading location 0x016d49c8.
Here is the disassembly point where it breaks.
7CA51406 mov ecx,dword ptr [eax]
Any ideas??

Does the problem happen before or after the DoModal() call?

I'm not sure.. I have remarked everything out in the code except the construction, DoModal and GetFileName and it takes between 2 and 10 times of opening the dialog and clicking OK before it will crash.

Which OK button, the one on your dialog, or the one on the File Open dialog?

Sorry I ment to say the 'Open' button on the CFileDialog..

It appears that m_ldFile.GetPathName() is causing the issue...

So if you commented out everything in between these two statements, would the exception persist:

Yeah, I think the part that is actually throwing the exception is m_ldFile.GetPathName() but I don't know why. The following trows the exception but if I remark out the m_ldFile.GetPathName() the exception stops.
static char BASED_CODE szFilter[] = _T("Text File (*.txt)|*.txt||");
CFileDialog m_ldFile(TRUE, _T(".txt"), NULL, OFN_HIDEREADONLY, szFilter);
if (m_ldFile.DoModal() == IDOK)
{
CString strFilePath = m_ldFile.GetPathName();
}

You might put a breakpoint on this statement and step into the GetPathName() method to get the exception narrowed down a bit further.

If you are using Visual Studio 8, enable breaking on first change exceptions in the debugger.
You can do that by going to Debug->Exceptions, expanding the Win32 Exceptions node and marking the ones you care about.
This will let the debugger stop where it's happening so you can narrow down the probelm.

I set the 0xC0000005 to break and it still doesn't really show anything it just goes directly into disassembly.
I did notice that I have to display the file dialog 2 times in order for the crash to happen.
I'm off to do some more testing...
