There are a number of reasons for an error, but you don't tell us what the error is. You seem to think we can guess.
Possible errors for the above code:
* The table tblcom doesn't exist
* The column date doesn't exist
* d1 is not a valid column name
* d2 is not a valid column name
* the keyword as is use incorrectly. Should this be and?
* the injected value s is causing a problem somehow.

Hello
I have created a custom installer that will display a form after the installation is completed.
There is the code for the installer class
<br />
Protected Overrides Sub OnAfterInstall(ByVal savedState As System.Collections.IDictionary)<br />
MyBase.OnAfterInstall(savedState)<br />
Dim myform As New Form1()<br />
myform.Show()<br />
End Sub<br />
I have added the project outputs on both the install and commit nodes in the custom actions.
When the installer finishes installing it will quickly flash the form and then disappear.
Can anyone tell me where I am going wrong.
Thanks in advance,
Steve

Your code doesn't block and wait for the form to return, so, when the OnAfterInstall event finishes, Windows Installer is pretty much done and quits. You have to show your form using .ShowDialog(), not .Show().
.ShowDialog() is a blocking call, so that code will wait until the dialog is closed before continuing.

You can't add controls to a PictureBox in VB6. You would normally use a Frame control for that.
In VB.NET, you can add controls to a PictureBox (it's does implement a Controls collection), but a Panel is much better suited for such things. More on it here[^].

Have you thought to read what the error is ? To check MSDN to make sure you're calling the function properly ?

I ran your code and it worked without error.

in vb.net how to use controlcollection to group all similar controls
|
|
|
|
|
A ControlCollection is not used for that. The Controls property of a control, which contains the children of the control, is a ControlCollection.
In what way do you want to group the controls?

It's amazing to see how much work some people will go through just to avoid a little bit of work.

I am making a button control. It is inheriting UserControl. I have everything complete except the damned click event, I can't seem to get it to fire. Any suggestions?

Hi, I've had the same problem. This is how I solved it :
The click event from the button isn't reachable outside the usercontrol.
But inside the usercontrol it is. So you have to handle the event inside the usercontrol and throw up a new event which is reachable outside the usercontrol.
A little code:
- create a control whith a button on it and add the following code to it:
- handle the event and raise a new one
Public Class UCButton
...
Public Event buttonKlik(ByVal sender As System.Object, ByVal e As System.EventArgs)
...
Private Sub Button_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)_
Handles Button1.Click
RaiseEvent buttonKlik(sender,e)
End Sub
...
End Class
- in the class or whatever where the new event has to be handled :
...
AddHandler Me.btnCommit.buttonKlik , AddressOf Me.commit_klik
...
Public Sub commit_klik(ByVal sender As System.Object, ByVal e As System.EventArgs)
...
do what you have to to
...
End Sub

Okay, I think the problem I may be running into the is there is no actual button control on the usercontrol. My "button" is actually a Panel with some custom drawing happening to it. I'm trying to capture the click event of the Panel, then pass it through.
|
|
|
|
|
And in looking at stuff, that is exactly what was happening. Thanks for the tip, you got me thinking in the right direction.

I'm glad you could use it.

Hello.
I need to create application using VB.NET that will parse csv file and import data into the database. I tried to read csv file but it returns funky characters. Did anyone had experience with this.
Thanks in advance.
Alex.

Perhaps if you posted your code, we could tell you why it's broken. In VS2005, there's static methods on the File class in System.IO that will read an entire file as a string array, and the split method on the string class will turn a string with commas in it into a string array also.

The problem is I don't have code. I just used something I used in the previous project to read a text file. If you can kindly point me into the right direction I woudl really appreciate that.
Thank you,
