My overall opinion is that you're screwed here. I have no idea what GCC files you need, and once you have them, they will create an exe that you can run. You're not going to be able to compile code within the process that you're running.

How many characters can a CEdit Control can obtain. In my App if I keep store data into CEdit, Cedit won't display data after a certain amount of time.
Thanks

Hi
Because the usage of DDX conversion to CString the edit box has the same limitations.
I have read somewhere that this would be around 30.000 byte in VC6.0 . I'm not 100% certain if this is true or if this limitation still stands in VC7.1 or VC8.0
You could probably load more data into an window without the usage of DDX functions or CString values.

Thank you for you replay. How could I use a CEdit control without DDX?
I use
m_pEdit->SetSel( -1, -1 ); // curser to text end
m_pEdit->Replace( strAddedText );
It displays for a while, then stucked.
Any solution?

Hi,
you've got to do it the hard way, dont use CString use a char buffer to access the edit box.
But char buffers are a very hard way to deal with strings so it would be better to use the std::string class. (this requires #include <string>
You will need to get the text from the control then append your extra data and next send the text back to the control. To simplefy this I wrote 2 wrapper funtions SetText and GetText. This gives the following code:
std::string CMyDlg::GetText(UINT uiControl)
{
CWnd* pWnd = GetDlgItem(uiControl);
if(pWnd)
{
std::string sTemp;
int iLen = pWnd->GetWindowTextLength();
char* pBuffer = new char[iLen+1];
pWnd->GetWindowText(pBuffer, iLen+1);
sTemp.assign(pBuffer, iLen);
delete pBuffer;
return sTemp;
}
return "";
}
void CMyDlg::SetText(UINT uiControl, std::string sText)
{
CWnd* pWnd = GetDlgItem(uiControl);
if(pWnd)
{
pWnd->SetWindowText(sText.data());
}
}
void CMyDlg::AddText(std::string sAdd)
{
std::string sText = GetText(IDC_MY_EDIT);
sText += sAdd;
SetText(IDC_MY_EDIT, sText);
}
This should work ...

Thank you for your reply. but I figured out a easy way, CEdit class member function SetLimitText(xxxx); set to -1 is maximum. It works fine. by default, it stops when getting 30000 bytes.
Good Luck

Hi Experts,
I am trying to move a DLL build in C++ from my desktop to Pocket PC
applications.
I build a new project in VS2005 C++, for "Smart Device", "MFC Smart Device
DLL", choose Pocket PC. And I copied all the source files (.h and .c .cpp) to
this new project. I have the error when i tried to compile it:
Error 1 fatal error C1083: Cannot open include file: 'mbctype.h': No such
file or directory C:\Program Files\Microsoft Visual Studio
8\VC\ce\atlmfc\include\afxv_w32.h 227
The DLL built for desktop application works fine (using VS2003). I checked
the Project properties, and found that in VS2003, i set "Use Managed
Extensions" to "No" under "configuration properties", but there is no such
setting options in VS2005.
Could you please tell me how i can solve this problem?
Thanks a lot!

Binary presentation of data
Hi all;
We all know that data stored in PC in binary code 1 or 0 ;
I need to know how we can to get binary code of file or
any thing
Thanks;
AMR-CIS

|

please be more precise... you need to get what exactly, and what for ?
is it for a display purpose ?
as you said : "We all know that data stored in PC in binary code 1 or 0" so why would you need to convert into binary, as whatever you manipulate so is already in that way in memory ?

well, to read binary from a file, use fopen to open a file, and fread to read unformated data from the file.
for the "any thing", you will need to be more precise in your question.

Can someone point me in the right direction for doing my first ActiveX control in Visual Studio .Net (MFC C++).
I have a MFC application that uses the USB joystick port, but would now like to convert it to an ActiveX.
Many thanks,

Hi all,
Iam working with a ListControl whose parent is a dialog. In the cell (1,1),I want to place a tree control which on doubleclicking should open up(ie: the width & height of this tree control exceeds the dialog boundary).
Will move the treecontrol & place it over the cell(1,1) position.
Now If I fix & width & I height of my treecontrol,I want the same size to be displayed,even if the parent dialog is smaller.
ie: If the childControl size is bigger than,the parentcontrol size ,it should overflow the parentcontrol boundary.(like if we click on a comboBox).
How can I achive this behaviour.
Any ideas
Thanks..

The dropdown listbox from a combobox is actually created as a top level window, a child of the desktop, and it is moved into place and shown when needed. You could do the same with your tree control.

Hi,
I did as follows in that order & I get the child control to exceed the parent window.
childControl.SetParent(GetDesktopWindow());
childControl.ShowWindow(true);
childControl.BringWindowToTop();
childControl.SetFocus();
childControl.MoveWindow(500,300,400,200);
But now the problem is ,I don't get the childControl as an activeWindow(Can't select,edit anything etc).
Thanks..

just declare a boolean flag which you switch in your OnStop() function...

Try AfxEndThread(..,..)
void AFXAPI AfxEndThread(
UINT nExitCode,
BOOL bDelete = TRUE
);
This will end the current thread.

Hi all
I've been teaching C++ for about 10 years (unmanaged using Borland Compilers), and for the first time this year I am teaching managed C++ using MS Visual Studio .NET. The first part of the course concentrates on procedural programming in a console environment, and one of the topics is writing / reading to text files (which is OK), and printing data to a printer (local LPT1 printer). In unmanaged code, I would write is as follows :
#include <fstream.h>
void main(void)
{
char data[80];
ifstream infile;
ofstream printer;
infile.open("TEST.TXT", ios::in);
printer.open("PRN");
while (infile)
{
infile.getline(data,80);
if (infile)
{
printer << data << "\n";
}
}
};
However, I cant find a simple way to set up a stream to the local printer in a console based environment using managed code. The file handling part is fine, and would look as follows :
// Filein1.cpp
#include "stdafx.h"
#using <mscorlib.dll>
using namespace System;
using namespace System::IO;
int _tmain()
{
String *record;
StreamReader * fileIn = File::OpenText(S"Test.txt");
// Need to set up stream to printer here
while ((record = fileIn->ReadLine()) != 0)
{
Console::WriteLine(S"{0}",record); // need to replace with output to printer stream
}
Console::ReadLine();
fileIn->Close();
return 0;
}
Can anyone help me fill in the gaps ?
Many thanks

Does anyone know how to use this!
I need to make the background of my AVI transparent. I'm capturing the OnCtlColorStatic message, but what next?
I search the docs and the web but have found conflicting examples. Should I be returning a BOOL from this message (to say I've handled it) or a HBRUSH? or something completely different!
I'm lost - Can anyone shed any light on this (a snippet of code would be useful!)
Kevin.
