Issue a resize message to the control like this:
DWORD dwEventMask=m_richedit_ayuda.GetEventMask();
dwEventMask|=ENM_REQUESTRESIZE;
m_richedit.SetEventMask(dwEventMask);
m_richedit.RequestResize(); Then, have EM_REQUESTRESIZE handled: there you are provided with the new size. It is up to you to do the actual resizing or not:
void CYourDlg::OnRichEditRequestResize(NMHDR* pNMHDR, LRESULT* pResult)
{
REQRESIZE *pReqResize = reinterpret_cast<REQRESIZE *>(pNMHDR);
CRect rect(pReqResize->rc);
m_richedit_ayuda.SetWindowPos(NULL,0,0,rect.Width(),rect.Height(),SWP_NOMOVE|SWP_NOZORDER);
*pResult = 0;
}

Bios Information - i'm want source code . please
I need Bios Information ( make date )
Go~~

If you only need general information about the BIOS you can simply read out the following 3 keys of the registry:
The name of the BIOS:
HKEY_LOCAL_MACHINE\\Enum\\Root\\*PNP0C01\\0000\\ "BIOSName"
Version of the BIOS:
HKEY_LOCAL_MACHINE\\Enum\\Root\\*PNP0C01\\0000\\ "BIOSVersion"
Date of the BIOS:
HKEY_LOCAL_MACHINE\\Enum\\Root\\*PNP0C01\\0000\\ "BIOSDate"
Happy coding!

RasSetEntryProperties changes an existing Dialup entry or creates it if none exists by the name provided. If you want to make sure the entry you are creating is fresh, use RasDeleteEntry first.

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.
