if it's registered, and has a typelib, you can add a wrapper class to your VC project. Project menu / Add to Project / Components And Controls. then VC will create a wrapper class for the ActiveX control that you can use.

I have create a .dll which compiles fine that I am trying to call from within VB.  It seems like something must be wrong somewhere because when I call the function it actually creates a new file and it just starts getting huge very fast, soon I had a file that was around 200 meg. Does something look goofy with the one function in you dll?
#include "Append.h"
void __stdcall AppendFile(char *pcMainFile, char *pcAppendThisFile)
{
ifstream inFile;
ofstream outFile;
int c;
inFile.open(pcMainFile, ios::in);
outFile.open(pcAppendThisFile, ios::app);
while(! inFile.eof())
{
c = inFile.get();
if(c != inFile.eof())
{
outFile << (char)c;
}
}
inFile.close();
outFile.close();
}
VB portion is declared as such
Private Declare Function AppendFile Lib "C:\Documents and Settings\User\Desktop\file\AppendFile\Debug\AppendFile.dll" (ByVal pcMainFile As String, ByVal pcAppendThisFile As String)
Private Sub Form_Load()
Call AppendFile("C:\Documents and Settings\User\Desktop\file\hello.txt", "C:\Documents and Settings\User\Desktop\file\nick.txt")
End Sub
Thanks in advance.

while(! inFile.eof())
{
c = inFile.get();
if(c != inFile.eof())
so which is it: does it return EOF or is EOF a property of the file?

Should it not be both EOF being a property of the file, which I am checking as I cycle through it. Did I miss something?

There are two eof() methods, which are easily confused due to the crappy STL docs.
basic_ios::eof() returns a bool indicating whether the stream has hit the end of the file.
char_traits<char>::eof() returns the character value that is returned by get() when the stream hits the end of the file.

Are the strings coming in to the C function correct? VB uses BSTRs, doesn't it?
Also, your if (c != inFile.eof()) should be if (!inFile.eof()). Your code compares c with the EOF flag of the stream, which isn't what you intended.

Ok, thanks Mike, I fixed that little bug however I am still creating a new file that dramatically gets large really fast. The only thing I am not really sure about now is the .def file used. It looks like this, I am not sure exactly how this is suppose to be structured, I used this structure as I read it in an example.
LIBRARY AppendFile
DESCRIPTION 'Append one file to another'
EXPORTS
AppendFile @1

here's a simple way to debug in this situation:
start VC. load your DLL workspace. put a breakpoint in AppendFile.
"run" it. when VC asks "which executable to use?" give it the path to the VB EXE (the actual Visual Basic IDE, not your VB app).
load your VB app and run it.

Is there a way to create a pane in a static splitter window based on an existing dialog resource? I've tried using CFormView and I've decided that the doc/view architecture is way to complicated. I am trying to achieve something similar to the Class View in VC++ 6.0 for a custom game editor I am working on.
Thanks,
-Matt

derive anew class from CSplitWnd, over load next two virtual function:
virtual CWnd* GetActivePane(int* pRow = NULL, int* pCol = NULL);
virtual void SetActivePane( int row, int col, CWnd* pWnd = NULL );
implement as follow:
CWnd* CTSplitterWnd::GetActivePane(int* pRow, int* pCol)
{
ASSERT_VALID(this);
CWnd* pView = GetFocus();
if (pView != NULL && !IsChildPane(pView, pRow, pCol))
pView = NULL;
return pView;
}
void CTSplitterWnd::SetActivePane( int row, int col, CWnd* pWnd)
{
CWnd* pPane = pWnd == NULL ? GetPane(row, col) : pWnd;
pPane->SetFocus();
}
I am seeking...
For what?
Why did you ask me for what? I don't know!

Then you're after docking windows, not a splitter. CP has a number of solutions, IMHO the best is this one:

I want to hide certain item's in my list view but I don't know how to do it. I've thought of making the hiden items having a height of 0 or simply not drawing them using custom draw but I have no idea how to do either of the two. I don't want to remove them from the list, just hide. Any ideas on how to do this?
There's always one more bug.

or GetDialogItem ( THE_EDIT_ID )->EnableWindow( value );
value = TRUE --> ENABLE
value = FALSE --> DISABLE

I would use
m_Edit.ModifyStyle(0, ES_READONLY) ;
This would allow the ocntent to still be copied to the clipboard by the user, but not change it.

Hello,
When using hotlinks for URL's in a Richedit Control, and then calling ShellExecute as follows:
<br />
ShellExecute(hWnd, NULL, pszURL, NULL, NULL, SW_SHOWNORMAL);<br />
The memory footprint of my executable will go up about 2 1/2 megs. Is there a way to free this memory up after a URL is clicked, or am I implementing something wrong here?
Thanks!
