Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged<br />
'show the selected customer name in a textbox<br />
TextBox1.Text = ComboBox1.Text<br />

Almost...
My form has more than one textbox control, for example, txtCustomerName, txtAddress, txtCity, txtEmail.
At design time I can set the binding source to each control's text property as such:
txtCustomerName I would set to - TblCustomerBindingSource - Cust_Name
txtAddress I would set to - TblCustomerBindingSource - Address
txtCity I would set to - TblCustomerBindingSource - City
So all my controls would look at their respective dataset, so when I scroll through my combobox, if I picked customer A then I would see the address, city, email etc. for customer a in my textboxes...subsequently if I chose customer B, I would see info for customer B etc.
I need to set this up manually, or unless there is a way that I can have multiple bindings to a textbox control because I also need to have those controls look at another table's / bindingsource.
Thanks.

I have a series of Reports that need to run from an ASP.NET website. So I'm creating 2 reporting classes.
1. Basic Reports
2. ReportLineItem
I'll need to overload the Basic report for the additional:
a. Financial
b. Geographical
c. Comparative Cost
Type reports.
And may need to overload the ReportLineItem with more detailed field's and calculations. The scope of the reports at this time is unknown. My question is how to us inheritance or implements within theses reporting classes to help me keep them flexable.
In the end the data mined and stored within these classes will be outputed into relational XML and formated with XSL-FO to produce PDF's. Any thoughts, help, or pass experances that may keep me from making a huge mistake is what I'm looking for.
Thanks.

i have two identical datagrids in my winform:
in one of them i have a vertical scrollbar that has to scoll the datagrids both and put them in the same position
well i can i do it with VS2003
in class mydatagrid
**************************************
ublic Class mydatagrid
Inherits DataGrid
Public Function getPositionScoll() As Integer
Dim pt As New Integer
If Not Me.DataSource Is Nothing Then
pt = Me.VertScrollBar.Value
End If
Return pt
End Function
Public Sub setPositionScoll(ByVal pt As Integer)
If Not Me.DataSource Is Nothing Then
Me.VertScrollBar.Value = pt
End If
End Sub
end class
*************************
in my winform
Private Sub DataGrid1_Scroll(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DataGrid1.Scroll
Dim ttt As Integer = DataGrid1.getPositionScoll()
DataGrid2.setPositionScoll(ttt)
End Sub
and the datagrid2 does not move
SECOND TRY
in class mydatagrid
**************************************
ublic Class mydatagrid
Inherits DataGrid
Sub ScrollToRow(ByVal row As Integer)
If Not Me.DataSource Is Nothing Then
Me.GridVScrolled(Me, New ScrollEventArgs(ScrollEventType.LargeIncrement, row))
End If
End Sub
end class
*************
in my winform
Private Sub DataGrid1_Scroll(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DataGrid1.Scroll
DataGrid2.ScrollToRow( an integer that you want)
End Sub
**********
now datagrid1's scrollbar moves datagrid2 to the the row but it moves only at that row...
the idea is in the scroll mathod event get the point of the scroll and than take the number of the first visible row of the datagrid1 and give it to DataGrid2.ScrollToRow:
For Each c As Control In DataGrid1.Controls
If c.GetType() Is GetType(VScrollBar) Then
pt = VScrollBar.MousePosition()
End If
Next
using pt point can i do what i want????
is this the right way to do it????
are there other ways to tune the position of my two datagrid with scroll????

Hi,
is it possible to create an object by its class name? I want to handle some objects (in my situation these are diffent window form classes) in a manager class, but i don´t want to create every window "by hand" like this:
Dim win as new CWindow1<br />
ManagerClass.RegisterWindow(win)<br />
<br />
Dim win2 as new CWindow2<br />
ManagerClass.RegisterWindow(win2)
What i want is something like this:
ManagerClass.CreateObject("CWindow1") <br />
ManagerClass.CreateObject("CWindow2")
The object handling should be completely managed by the ManagerClass.
I found some information about the Activator class, but i don´t know if its possible to use it for my problem
Thanks for your help.

Create a Type object from the class name, use the GetConstructor method to get a ConstructorInfo object, and use it's Invoke method to create the object.

first of all i m unable to follow this statement( may causing problems)
avinashprabhu.t.p wrote: boolVisible = True = False

The statement is a bit more readable in this form:
boolVisible = (True = False)
As the two operands are not equal, the (True = False) comparison will result in the value False. That means that the code does the same as:
boolVisible = False

Hi,
I'm working on VB.Net (Window Base), I have add crystal report in my application. When I make a setup file in my own PC and I have try to run the exe file, it seem work nice on my own PC. Then I try to run the setup in other machine, and try to run the exe as well, when I open the report from it, it give me a error msg. The error msg are look like this 'Cannot find keycodev2.dll or invalid keycode.'
Can anyone teach me step by step to slove this error? Thanks.

it's actually quite simple. assuming you've added a setup project to your solution, what you gotta do is
1. right click on the setup project in solution explorer and go to "
Add > Merge Module..."
2. add the Crystal_regwiz2003.msm to your project.
3. to get your license key, click on "Help > About Microsoft Development Environment", click on the list box item for crystal reports and then click on the "copy info" button.
5. now right click on Crystal_regwiz2003.msm in solution explorer and select "Properties".
6. expand the (MergeModuleProperties) node in the properties window. you should see a "License Key" property. Paste the license key that you obtained from step 3 (remember to delete the other junk that was copied with it).
to explain a bit... (from MSDN)
Crystal_regwiz2003.msm configures registration information on deployed computers (server or client) in order to track licensing information.
When Crystal_regwiz2003.msm is added to a setup project, it exposes a LicenseKey property that must be set before building the setup project.
The license key is emailed to you when the product is registered. This key is also available from the About Microsoft Visual Studio .NET dialog box from the Help menu. Enter this license key into the LicenseKey property for the Crystal_regwiz2003.msm merge module.
Note: If the license key is not set for the Crystal_regwiz2003.msm merge module, an error will occur when building the project. If the setup is installed on a target computer without specifying the license key for the merge module, various keycodedev2.dll errors will occur.
---
sorry for the long explanation.

In the step 6, it is I only need to paste the 19 digit inside the license key? After paste the license key, I have try to build the setup by right click the setup file at the solution explorer and choose build. After success everyting, I have copy the setup file and try to install at other machine, but the error still come out? What mistake I have make? Can give some advice?

|

have you also included the correct merge module for your database type?
|
|
|
|
|
What you mean by merge module for my database? I not understand this? Can you explain a bit? Thanks.

|

erm... read this[^]
they always put it better than i can.

|
|
|

Hi,
I already follow your step by step to create the setup file and the licensing key. but also have the same error. I really dun know what mistake I have make. I have try many way to found out the error, but also no use. so what should I need to do?
|
|
|
|
|
you followed this[^] step by step? then you shouldn't have a problem (solved it for me...)
how big is your app? if it's not too big and if you'd like to, zip it and mail it to me and i'll see where you've gone wrong and point you in the right direction.
