Problems wit events



  • 1. Why do my events not fire?
    Not to worry - discovered the problem. I was changing the children control's ID's before render but after init. so the controls that were generating the command events were called something different when they raised the events than when they were meant to be receiving the events.

    Hi, I have a usercontrol with a button. In the button's click event I have to open an instance of an aspx page, passing some values to some public variables of the page.

Hi, everybody

I have a problem with the events in a web page.
I have a botton with a method that should execute a method on mouse click
but for some reason (that I don't know) it is executing the page_Load before
the method call, WHY?
    What I need is that the method be called before any event and If its
possible to cancel the Page_Load, or where else I can set this code in the
button.  This is what I have. The Page_Load always gets fired when I click
onm btnBuscar. Any ideas.

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
    If IsPostBack Then
    End If
End Sub

Private Sub btnBuscar_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles btnBuscar.Click
Dim condicion As String
condicion = ""
PrepareCondition(Page, condicion)
If condicion.Length <> 0 Then
condicion = " WHERE " & condicion.Substring(4)
End If
Session("tcWhere") = condicion
End Sub

Also I have another problem if i refresh the page with F5 function key, the
click event on the botton always gets re-executes.

Thanks ahead,

The Page_Load event is always called before any control 
event.  Try placing your Page_Load code into a method and 
call the method from Page_Load using the IsPostBack 
property to only call it on the first page load then you 
can call it from your controls event if you need to but 
it wont execute after a post back.

4.Problem wit std::string::substr

Hi all,
Following code causes strAddress to contain garbage data.
When I decrease number of characters that appear before '\\' then everything
is ok.
12 chars before '\\' seems to be a magic number.
I have compiled it with VisualStudio 2003.
Any ideas?

std::string strAddress = "123456789012\\aaaaa";
std::string::size_type pos = strAddress.find('\\');
if( pos != std::string::npos )
    strAddress = strAddress.substr( pos + 1, 2 );

Thanks in advance for any help.

5.Help Please Wit Error

Hey Guys,

I trying to create an application that uses an OLEDBConnection.
Every time I try to run my app when I get to the opening of the 
connection I get this error.

"The .Net Framework Data Providers require Microsoft Data Access 
Components (MDAC).  Please install Microsoft Data Access Components 
(MDAC) version 2.6 or later."

I have downloaded the latest version of MDAC (2.7) and installed it but 
i still get the same error. I downloaded this utility from MS and its 
supposed to check which version of MDAC i have installed and it says I 
have all of them installed from 2.1 to 2.8 sp1. It doesn make any 
sense, I have used this type of connection before but i have formatted 
since so I not sure if there is some little setting that i missed or 
if i just got lucky last time. Any input will be greatly appreciated so 
thx in advance.
