Hi!
I'm trying to use an ActiveX dll in my C++ program.
The dll is written in VB (not by me), so I generated a h-file from the idl.
Everything compiles, but when I run the test program I get
an error at the line with a  below.
The code is really simple, but I don't know what is causing the
error. Anyone familiar with what might be wrong here? Thanks...
<br />
void TestDlg::OnOK() <br />
{<br />
HRESULT hRes;<br />
_cTheObj *pTheObj = NULL;<br />
<br />
UpdateData(TRUE);<br />
<br />
hRes = CoInitialize(0);<br />
<br />
if (SUCCEEDED(hRes))<br />
{<br />
hRes = CoCreateInstance(CLSID_cTheObj, NULL, CLSCTX_INPROC_SERVER, IID__cTheObj, (LPVOID *)&pTheObj);<br />
<br />
if (SUCCEEDED(hRes))<br />
{<br />
SHORT ret;<br />
VARIANT l1;<br />
VariantInit(&l1);<br />
l1.vt = VT_BSTR;<br />
l1.bstrVal = m_logon1.AllocSysString();<br />
<br />
hRes = pTheObj->Logon(l1, &ret); :confused:<br />
The definition of the Logon funcition in the h-file for the dll looks like:
<br />
virtual HRESULT STDMETHODCALLTYPE Logon( <br />
VARIANT arg1,<br />
VARIANT arg2,<br />
VARIANT arg3,<br />
VARIANT_BOOL __RPC_FAR *__MIDL_0014) = 0;<br />
Thanks for any help!

Looks like you are only passing one argument where it is expecting 3, and looks like it might not be initialized, at that.

Oh, I'm sorry! I only removed the other variables from the code presented to you, to make it more readable!

I have inherited my controller from a CListCtrl. But I want to change so the double click message is not sent. I want the OnLButtonDown message to always be sent. Don’t want any double click.
From want I understand is I need to remove the CS_DBLCLKS from window class style that is registered.
How do I do that ? or should it not be changed since it’s a standard controller.? Should I register and use a new class info? how do I do that from an inherited class ?

I'm not sure, if I understood you properly, but I guess that you should do something like this:
1. Run ClassWizard.
2. Go to Message Maps tab.
3. Choose your class (on the left-hand side).
4. Find WM_LBUTTONDBLCLK (on the right-hand side).
5. Hit Add Function and then Edit Code.
6. Remove (e.g. comment out) standard message handler and, if you want to, add your own (e.g. a message box saying that double clicks are disabled).
void CTest::OnLButtonDblClk(UINT nFlags, CPoint point)
{
AfxMessageBox("Double clicks are disabled.");
}
Let me know if this was helpful.

No. the Double click event from windows is still sent to the applications.
so when i click too fast, I only get 1 respone to OnLButtonDown() insted of 2.
the problem is that the window class has the CS_DBLCLKS flag set. and this
tell the OS that this windows should recive the double click event.
So I need to remove that.
AND i just found the solution. after searching the net for some hours.
this worked.
BOOL CMyListCtrl::Create( DWORD dwStyle, const RECT& rect, CWnd* pParentWnd, UINT nID)
{
if( CListCtrl::Create(dwStyle, rect, pParentWnd, nID) )
{
DWORD dwStyle = GetClassLong( GetSafeHwnd(), GCL_STYLE);
SetClassLong( GetSafeHwnd(), GCL_STYLE, (dwStyle ^ CS_DBLCLKS) );
return TRUE;
}
return FALSE;
}

Try the PreTranslateMesssage event handler.
[MODIFIED]I guess you have found your solution and it even far more better. Glad it works out that way and I have learned. [/MODIFIED]

hi,sorry,
MyCombobox's data is empty,the data
i has input is not belone Mycombobox,
GetLBText() will cause a error;
the data i has input is the exe run
|
|
|
|
|
well..'MyCombobox' is just a test name (i made it up), you gotta replace it with a CComboBox instance that represents the combobox you want to read the text from.

I know,
my question is :
i can't get the text in CComboBox that i input when the program is run
(CComboBox m_DBName);
int index=-1;
index=m_DBName.GetCurSel();
//if i input "sdfs",the next cause a error
str=m_DBName.GetCurrentText();
|
|
|
|
|
replace "str=m_DBName.GetCurrentText()" with
CString str;
m_DBName.GetLBText(index, str);
"str" should now contains the text in the combobox.
Note: verify that 'index' contains the right index in the combobox.

Take a look at GetWindowText. It should do it !
|
|
|
|
|
the function GetWindowText Can't use ,CComboBox modify it
