Como Exportar de Flexgrid a Excel
como exportar un arhivo a excel, usando un MsFlexgrid O MsHflexgrid, bueno consegui este codigo y uso el MSHFlexGrid, pero lo pueden cambiar a MSFlexGrid, sin ningun problema..

Código:

Minimizar en el Systray con Menu
Este es un modulo que nos permite minimizar nuestra aplicación al lado de la hora y nos brinda la posibilidad de ponerle un menu. este codigo me lo baje de una web yo solo le ise algunos arreglos para que el codigo estubiera mas organizado y fuera más facil de usar. todo el codigo estaba en el form y yo lo lleve a un modulo. y ise las funsiones. No pongo el nombre del autor original porque no estaba en los codigos junto a los comentarios .

'------------------------------------------------------------
' Pequeño Manual
'------------------------------------------------------------
'*Este pequeño manual es para usar correctamente este Módulo*
'
' - Este Módulo cuenta con dos funciones-
' (YCCSysTrayMinimizar y YCCSystrayMenu)
'
' Como usar correctamente YCCSysTrayMinimizar:
'
' Antes que todo esta función es la que ase que nuestra aplicación
' aparesca en el Systray de Windows(al lado de la Hora del sistema)
' Datos que debe entrar
'.FORM (Aqui debe entrar el nombre del Form donde usa la función)
'.ToolTipText (Aqui se entra el texto que se mostrara cuando se
' situe el cursor sobre el icono de nuestro systray)
'.ShowInTaskbar ( si es true cuando se minimize la aplicación se
' mostrara en el Taskbar(Barra de tareas) si es
' False no se mostrara.
'
' *******Donde usar esta Función*********
' En los eventos Load y resize del Form.
' En el evento Load: si quiere que siempre nuestra aplicación
' aparesca en el systray. en este Evento coloque ShowInTaskbar
' con valor True de lo contrario el Form iniciara Invisible
' si desea que el form nunca se muestre en el Taskbar
' (Barra de tareas) en las propiedades del Form ponga
' ShowInTaskbar en False.
'
' En el evento Resize: si quiere que aparesca apartir
' de la primera vez que se minimize nuestra aplicación aquí
' si puede colocar ShowInTaskbar con valor False.
'
' Como usar correctamente YCCSystrayMenu:
' Esta función es la que ase que se le pueda asignar menu al
' systray de nuestra aplicación Datos que debe entrar
' -- Datos que debe entrar
'.FORM (Aqui debe entrar el nombre del Form donde usa la función)
'.x (Solo tiene que poner una x)
'.Menu (colocar el nombre de un menu que exista en un form
' de nuestra aplicación)
' si quiere que el menu solo aparesca en el systray ponga su propiedad Visible en False.
' OjO esta funcion siempre debe ir en el Evento MouseMove del Form

Como reproducir MP3
Escribimos en un módulo:

Código:
Declare Function mciExecute Lib "winmm.dll" (ByVal lpstrCommand As String) As Long


Para reproducirlo:

Código:
iRESULT = mciExecute("Play C:\Chiquita.mp3")


Para detener la reproducción

Código:
iRESULT = mciExecute("stop C:\Chiquita.mp3")

Como conectar un DbCombo a una Base de datos
Para conectar un DBCombo un DbList usamos el siguiente codigo

Código:
Private Sub Cargar_Clientes()
Dim AdoP As New Recordset
Set AdoP = New Recordset
AdoP.Open "SELECT   `clientes`.`nit_cliente`,  `clientes`.`nombre` FROM   `clientes` WHERE   (`clientes`.`cliente` <> 0) ORDER BY `nombre`", Cxn, adOpenStatic, adLockOptimistic
Set CboCliente2.DataSource = AdoP

Como hacer un boton en Flash para VB6
hace un boton en flash. y le colocas esto esto en el evento on_release

Código:
 on (release){
    fscommand("elmensaje");
 }


despues te vas al proyecto de vb6 y agregas tu shockwaveflash ya con el botoncito y todo muy bonito...(jaja)

depues de haber insetado el shockwaveflash, cargas tu botoncito..

digamos que tu boton se llama botonswf.swf

entonces el form load agregas esto..

Código:
ShockwaveFlash.Movie = App.Path & "botonswf.swf"


bueno despues en shockwaveflash haces doble click y dentro de los procedimiento seleccionas el FsCommand

Código:
 Private Sub ShockwaveFlash_FSCommand(ByVal command As String, ByVal args As String)
 Select Case command
     Case "elmensaje"
            msgbox "Este es el mensaje pasado desde flash..",vbinformation,"mensaje"
 End Select
 End Sub


de esta manera tenes un boton de flash insertado en vb..

Código:

 Como conectarme a MySQL desde VB6
1ro. Tener instalado un servidor Mysql con el puerto 3306 abierto y tener configurado el usuario correctamente para poder acceder remotamente o bien sea via localhost.

2do. Tener instalado en la computadora Cliente el Mysql ODBC Driver 3.51, que lo pueden descargar de Mysql.com


3ro. bueno.. el codigo..

Código:
        Dim Cxn As ADODB.Connection
        Dim AdoS As ADODB.Recordset
   Dim CxnFac As String
   Set Cxn = New Connection
   Cxn.CursorLocation = adUseClient
   CxnFac = "Driver={MySQL ODBC 3.51 Driver};Server=IpServer;Port=3306;Option=131072;Stmt=;Database=recepfac;Uid=root;Pwd=TuContrasena;"
   Cxn.Open CxnFac ' Abrimos la conexion
   Set AdoS = New Recordset
   AdoS.Open "Select * From clientes", Cxn, adOpenStatic, adLockOptimistic ' Abrimos el REcordset y esta listo para usar
   MsgBox AdoS!nombre


Bueno basta decir que este caso tenemos una tabla llamada clientes que posee un campo llamado nombre..

ProgressBar al estilo Windows 95
Este código sirve para simular una ProgressBar al estilo Windows 95 en un control PictureBox. Espero les guste, ya que sólo con cambiar el ForeColor del PicBox cambian el color de la barra y su texto, también si ponen el Pic en Flat y a Fixed Single toma una apariencia bastante atractiva, cosa que el ProgressBar de los Common Controls no trae:

Código:

    Dim strPercent As String
    Dim intX As Integer
    Dim intY As Integer

    On Error GoTo ErLg

    If pctBox Is Nothing Then Error 5

    pctBox.AutoRedraw = True
    pctBox.BackColor = vbWhite

    intPercent = Int(100 * PercentValue + 0.5)

    If PercentValue < 0 Or PercentValue > 1# Then Error 5
