RAD.On++ home how to foundation user guide  
HOW TO...(feel free to ask us everything about RAD.On++)
1) If you get troubles while installing RAD.On++, check out the file named setuplog.txt into the setup folder. Otherwise refer to the file named instlog.txt into the RAD.On++ folder to know which files to remove if you want to uninstall it.
2) Note that Visual C++ assumes a couple of environment variables INCLUDE and LIB to be set which specify the location of the includes and libraries. Your PATH environment variable also needs to include the DevStudio vc\bin and sharedide\bin directories. Visual C++ installs a batch file called vcvars32.bat in \Program Files\DevStudio\VC\bin\ (or wherever you installed it) that you can run before building to set up all of these environment variables. If you do not confirm to register those variables when Visual C++ asks to you during installation, you can type vcvars32.bat(complete with path) into the "start with batch command" edit control in the RAD.On++ "preferences" dialog or simply follow the Windows OS procedure to register those variables by the properties system dialog(the link is on the desktop).
3) When you are editing scripts or code snippets you can magnify the font pressing the CTRL key with the + or - or / keys on the nuneric keypad: + to zoom in, - to zoom out, / to reset zoom.
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:
  • 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

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");
How to put a GIF or JPG or 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

Than put the following lines of code into the WM_CREATE event of your form:

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;

ip=reg.Query("DB Address");
::os.FatalMessage("Invalid ip address.");
xstring driver=reg.Query("Driver");
reg.Store("MYDB","SQL Server");
terminate = __stop;
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();
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

then bind an icon to your main form(be sure the icon contains 16x16 image size) - right click on your main form and choose bind icon... from the popup menu;
choose the icon file and set 32x32 size in the dialog
make the form hidden
- right click on your main form and choose attributes from popup menu;
choose the load only show mode
- finally put the follow code into the WM_Create event of your main form:

Ok. You have your icon on the SysTray. Now you can trap the mouse click on the icon by the zWM_NotifyIcon event of your main form:

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:
