| How to arrange
a free Win32 Microsoft C++ |
There are a lot of free Microsoft
products which permit you to arrange a free Win32 C++ compiler. I will
show you my own ways:
|
| Visual Toolkit 2003
|
| Visual C++ 2005 Express
|
Visual C++ 2008 Express
- Download and install the Visual C++ 2008 Express:
http://www.microsoft.com/express/download/
- Modify the windows globlal environment variables PATH, INCLUDE
and LIB adding some folders as follow:
PATH: ...;C:\Program Files\Microsoft Visual Studio 9.0\VC\BIN;C:\Program
Files\Microsoft Visual Studio 9.0\Common7\IDE;C:\Program Files\Microsoft
SDKs\Windows\v6.0A\bin
INCLUDE: ...;C:\Program Files\Microsoft Visual Studio 9.0\VC\INCLUDE;C:\Program
Files\Microsoft SDKs\Windows\v6.0A\Include;
LIB: ...;C:\Program Files\Microsoft Visual Studio 9.0\VC\LIB;C:\Program
Files\Microsoft SDKs\Windows\v6.0A\Lib
- THAT'S ALL!

| How to convert a DIB file
to a JPG file |
First of all mark the xdib check box and the INTEL JPEG library check box into the #define manager dialog
To execute the following peice of code, you must have the Intel Jpeg Library(click here to download the INTEL JPEG library)
xdib dib;
...
dib=xpath(::module.Path()+"pic.bmp");
dib.Save2JPG(::module.Path()+"pic.jpg");

WMF background image into a form |
First of all mark the xolepicture check box and the xfiles check box into the #define manager dialog
If you want, you may choose the image bits mode from the form attributes dialog

| How to quickly define foundation
classes usage |
Note: you can still define component usage by the compiler option /D in the Options->Preferences dialog.
From main memu do Options->Preferences->Defines, the following dialog will pop up
now mark all the foundation components you want to use and confirm to exit.
Note: this will act as a rebuild all for the next compilation request.

| How to obtain tokens from
strings |
First of all mark the xtokens check box into the #define manager dialog
Quickly extract values from string(which often are delimited in various mode)
xstring tok = "DEF=1;3;44;8";
tok.delimitToken("=;");
tok.startTokenize();
int num;
while((num = tok.currentToken()) !=0 ){
//the integer variable 'num' will be on turn: 1 3 44 8
tok.nextToken();
}
xtring tok = "(mary)";
tok.delimitToken("()");
tok.startTokenize();
xstring name = tok.currentToken(); // the string name will contain mary
.
the next example is an excerpt form RAD.On++ source code
//LOAD FOXPRO KEYWORDS FOR SCINTILLA SYNTAX COLORING
xarray<xstring>ckeywords;
xstring tok = xpath(xstring(RAD.Onfolder) + "fpkeys.txt");
tok.delimitToken(",\r\n");
tok.startTokenize();
while(tok.currentToken().isNotNull()){
ckeyword[ckeyword.Grow()] = tok.currentToken();
tok.nextToken();
}

| How to set-up the registry
from applications |
First of all mark the xregistry check box into the #define manager dialog
Here is how to set-up the windows registry on the fly for a SQL SERVER client connection from your application:
bool sqlregsetup(void){
bool terminate = __continue;
xregistry reg;
TRY
reg.Open(HKEY_LOCAL_MACHINE,"SOFTWARE\\MYPROGRAM");
ip=reg.Query("DB Address");
IF(ip.isNull())
::os.FatalMessage("Invalid ip address.");
RAISE(__stop);
ENDIF
reg.Close();
reg.Open(HKEY_LOCAL_MACHINE,"SOFTWARE\\ODBC\\ODBCINST.INI\\SQL Server");
xstring driver=reg.Query("Driver");
reg.Close();
reg.Create(HKEY_LOCAL_MACHINE,"SOFTWARE\\ODBC\\ODBC.INI\\ODBC Data Sources");
reg.Store("MYDB","SQL Server");
reg.Close();
reg.Create(HKEY_LOCAL_MACHINE,"SOFTWARE\\ODBC\\ODBC.INI\\MYPROGRAM");
reg.Store("Driver",driver);
reg.Store("Database","MYDB");
reg.Store("Server","MYSERVER");
reg.Store("Language","Italiano");
reg.Close();
reg.Open(HKEY_LOCAL_MACHINE,"SOFTWARE\\Microsoft\\MSSQLServer\\Client\\ConnectTo");
reg.Store("MYSERVER","DBMSSOCN,"+ip);
CATCH_ALL
terminate = __stop;
ENDCATCH
return terminate;
}

| How to implement the BlowFish
Encryption |
First of all mark the xblowfish check box into the #define manager dialog
void blow(void){
xblowfish bf;
xstring out,in=form.TEXT2BLOW.Text().SpaceTrim();
int len=in.Length();
if(len==0){
form.TEXT2BLOW.Focus();
return;
}
if(len<8){
in.AppendNulls(8-len);
len=8;
}
bf.Init((PBYTE)"blowseed",8);
out.Spaces(bf.OutputLength(len));
bf.Encode(in,out,len);
}

| How to put an icon on the
SysTray and how to link a popup menu to it. |
First of all mark the icon on systray check box and the xpopupmenu check box into the #define manager dialog

this snippet code will show the main window on foreground.
If you want to show a popup menu on mouse right click use the following way:
