Hi,
Guys I need your guidance..
I have MdiForm with a progress bar. when I save on a child form, I want to have the progress bar to show the saving progress.
To be more clearer, when I click save_button on a child from, the bar should show progress and then reset after the saving method is done.
Thanks

Add a Statusbar to your MdiForm and show the progressbar on the statusbar when saving.

How to close all open forms without current and startup forms?
|
|
|
|
|
Get the list of open forms by Application.OpenForms collection. Then, identify the current form and the start up one from the list. Close the rest of them. You can identify current one by matching the name or something and same goes for the start up form.

Check out SqlDataSourceEnumerator class. That will help you getting the list of SQL server instances on the network.

u can use sqldatasourceenumerator to get the available sql instances
like
Dim dt As New DataTable
dt= Sql.SqlDataSourceEnumerator.Instance.GetDataSources
DataGridView1.DataSource = dt.AsDataView

Hi there,
I am currently trying to generate a report based on crystal report 10. In my report there are some parameters that should be displayed only once, some parameter for every record but some only a few times. Here is what i did, I put those parameters that will be
1. displayed once on the page headers
2. displayed for every record from the database in details section, and I used GROUPING for others.
Name____Col1_____Col2____Col3____Time
______________________________Dias_Horas_Minutos
SUBAREA_a
X____test____AAAA____AAAA1____1____2____3
Y____test____BBBB_____BBBB1____3____2____1
_____________________Subtotal____4____4____4
SUBAREA_b
X____test____AAAA____AAAA1____1____2____3
Y____test____BBBB____BBBB1____3____2____1
_____________________Subtotal____4____4____4
SUBAREA_c
X____test____AAAA____AAAA1____1____2____3
Y____test____BBBB____BBBB1_____3____2____1
_____________________Subtotal____4____4____4
_____________________TOTAL____12____12____12
My question is that possible to have a sub-grouping with grouping in Crystal report?
with regards,

Just call them;
Private Sub Button1_Click(sender As Object, e As EventArgs)
Button2_Click(Nothing, EventArgs.Empty)
Button3_Click(Nothing, EventArgs.Empty)
End Sub

Why not have a single handler for all the buttons? Then you can wisely put some conditions so that only a particular code is fired depending on the button clicked.

I like Danish's method
Private Sub ClickAllButtons(sender As Object) Handles Button1.Click, _
Button2.Click, Button3.Click
Dim btn As Button = Nothing
If TypeOf sender Is Button Then
btn = DirectCast(sender, Button)
If btn.Name = "Button1" Then
callButton1Stuff()
callButton2Stuff()
callButton3Stuff()
ElseIf btn.Name = "Button2" Then
callButton2Stuff()
Else
callButton3Stuff()
End
Else
' Maybe a good idea to do something here.
Exit Sub
End

Hello,
I am programming in VB2005.
I have a Form1 and Class A:
a) In Form1, I have a Picturebox (Name=PictureBox1)
b) Class A inherits from PictureBox
I am trying the following but the Picturebox1 does not display anything:
Dim MyA As New A(PictureBox1.Width, PictureBox1.Height)
MyA.Location = New System.Drawing.Point(150, 150)
MyA.BackColor = Color.Red
PictureBox1 = MyA
Why doesn't it works?
I have an alternative to solve the problem but I would like to understood the problem above.
Alternative sdolution:
Dim MyA As New A(500, 350)
MyA.Location = New System.Drawing.Point(150, 150)
MyA.BackColor = Color.Red
controls.add(MyA)

Why don't you use real variable names ?

This is a bit dumb. What you need to do, is either change your picturebox to be a ClassA, or you need to just create a picturebox and add it to the Controls collection of the form.

My ClassA inherits from PictureBox object.
Now my form1 is creating a new instance of class A and this new instance will "return" a PictureBox that I would like to display on my form1. So I though to do the following form1.PictureBox1=NewInstanceOfClassA to display the result of new instance of ClassA to my form1.
...or you need to just create a picturebox and add it to the Controls collection of the form.
WHay to add it if already exists in my form1, I only want to overwrite it with my new instance of class A
Thank you

Start by highlighting the differences between the first and the second code. What does controls.Add do?

In the first code PictureBox alrady exists so I do not have to add it.
In the second code PictureBox doesn't exist so I am adding it at run-time.
So what now?

PictureBox1 = MyA This would not 'replace' the PictureBox1 in memory with an MyA, and I don't know whether the property is smart enough to add the control to the controls-collection on it's own.
