Oh, then I guess that this folder gets created when installing MS Outlook and isn't there by default. GetWindowsDIrectory() is working for me and I just add \Local Settings\Application Data\ to it.
My only concern is if \Local Settings\Application Data\ will still be in english for other languages, such as french... Anyone knows?
Thanks for your help!

Yes, this folder is always in English. Only folders that will be in other languages are, as far as I know, "Desktop" and "Startup".

For CSIDL_LOCAL_APPDATA and CSIDL_WINDOWS, you must have v5 of the common controls DLL. What version of Internet Explorer does the Windows 98 machine have?

When I've tried to catch keyboard messages with SetWindowsHookEx(WH_KEYBOARD, KbHookingProc, hinstDll, 0), I've noticed, that only WM_KEYDOWNs are hooked.
It means that, as I make an attempt to send the message to my primary thread of execution like this:
LRESULT CALLBACK KbHookingProc(int code, WPARAM wParam, LPARAM lParam)<br />
{<br />
if (code < 0) goto ret;<br />
<br />
UINT uMsg = (lParam & KF_UP) ? WM_KEYUP : WM_KEYDOWN;<br />
<br />
PostThreadMessage(ThreadId, uMsg, wParam, lParam);<br />
<br />
ret:<br />
<br />
return CallNextHookEx(hhook, code, wParam, lParam);<br />
};
I recieve only WM_KEYDOWN messages.
So, when my primary thread tries to translate such re-sent messages, TranslateMessage doesn't work (I suppose, it depends on WM_KEYUP in some way, but I'm not sure).

Hi all,
My problem is that I am writing an application using ODBC to connect to an Access database. I have since found out that the there is a problem putting a datetime object into this database.
I found an article at Codeguru... which does fix that problem but on to my current problem. When I enter in a Date Time with the DateTimeCtrl then I advance to the next record or any record and it continues stuffing my original selection into every record.
Thanks,
Steve

Hi,
I have an editable CTreeCtrl, in the function OnEndlabeleditTree() I decide whether I would save the change or, not. The problem is at the end of the function I check the ItemText of the edited label and it always remains unchanged although the label actually changes. Please tell me how I can actually reflect the change in the program. Here is the code:
void CGeneratorView::OnEndlabeleditTree(NMHDR* pNMHDR, LRESULT* pResult)
{
TV_DISPINFO* pTVDispInfo = (TV_DISPINFO*)pNMHDR;
HTREEITEM hItem = pTVDispInfo->item.hItem;
CEdit* pEdit = m_TreeCtrl1.GetEditControl();
CString str;
pEdit->GetWindowText(str);
if (str.IsEmpty())
{
MessageBox("Please enter a valid Label!");
*pResult = FALSE;
return;
}
else
{
*pResult = TRUE;
}
m_TreeCtrl1.SelectItem (hItem);
MessageBox (m_TreeCtrl1.GetItemText(hItem));
}
|
|
|
|
|
From what I understood OnEndlabeleditTree() get's after edit finished, but before actual tree item changed. Therefore, your MessageBox (m_TreeCtrl1.GetItemText(hItem));
inside OnEndlabeleditTree()is premature.
You may use your str at this point, however if you expect item text to be changed somewhere and really want to figure out what text should be -- post User Message to yourself and MessageBox items text in it's handler.

Instead of yours:
m_TreeCtrl1.SelectItem (hItem);<br />
MessageBox (m_TreeCtrl1.GetItemText(hItem));
Do the following for example:
PostMessage(WM_APP+1, (WPARAM)hItem, 0L);
Now, create WindowProc handler if you don't have already, and put the following code there:
LRESULT CYourWnd::WindowProc(UINT message, WPARAM wParam, LPARAM lParam) <br />
{<br />
if(message == WM_APP+1)<br />
{<br />
MessageBox (m_TreeCtrl1.GetItemText((HITEM)wParam));<br />
}<br />
...

I am working on a Vc++ Dialog app with ATL support .

Where is the #include < excel8.h > statement?

it is there in the projectDlg.h file

It should go in the stdafx.h file.

Plus using classwizard I am not adding all the zillion classes within Excel . I am adding the classes that I need . Would that be a problem ?

i am doing some Excel automation stuff and needed to convert a char * to a VARIANT
SysAllocString needs a unsigned short * which doesnt convert correctly from a char *
Is there a function that will allow me to assign a char * value to a VARIANT ?

|

Take a look at the _variant_t wrapper class.

I need to pass a pointer to a _com_ptr_t object (as created by the #import directive), but I can't take the address of it, since the & operator is overriden by the class to return the underlying interface pointer.
eg:
void f( ADODB::_RecordsetPtr *pRs1, ADODB::_RecordsetPtr *pRs2 )
{
if ( NULL != pRs1 )
{
}
if ( NULL != pRs2 )
{
}
}
ADODB::_RecordsetPtr pRs;
f( &pRs, NULL ); Yes, I can pass it by reference, but I want a pointer since the object is allowed to be NULL if it is not required.
Any ideas?
Thanks!

Always pass smart pointers by value; it's cheap and that is what they are there for. You can test the smart pointer for NULL just like a regular pointer: if it hasn't been set to anything, converting to bool will return false. (you can just use
if ( ptr )
which implicitly converts to bool)

Wait a second, I think a light just came on in my head... 
I need to CreateInstance on the pointers that I need and then pass those to my function. Any pointers that have not had CreateInstance called on them will be false, so I know I cannot use them...
Hmmm... that will work, but I was hoping to be able to get my function to call CreateInstance on the smart pointer if it was not NULL, thereby creating it for me.
Thanks for the insight!

I am porting a C++ app written on Unix over to Windows using VS. It balks at a function declared and defined in the h file:
template <class T>
T *
s_file::port_data (unsigned int line) {
return ((T *) _port_data + line * _port_samples);
}
I am going to have to write overloaded functions to replace this, but is there a simpler resolution? Apparently VC does not like a template fn embedded in a class ??
Thanks,
Appreciate your help,
ns
