View 7 RepliesI recently saw some VB .NET code as follows:[code]Does assigning Nothing to service do anything? If it is a garbage collection issue, I am assuming that when "service" went out of scope the referenced object would be garbage collected and the dispose method called on the object.It seems to me that assigning this variable Nothing can't really do anything, as there could be another reference to the object around so the reference counts haev to be checked anyways.
View 6 RepliesWriting a custom validator for a dropdownlist that is using autopostback. Seems to ignore the validation altogether. Why is it ignored and is there an easy fix? Note I did not use ControlToValidate
asp.net:
<asp:UpdatePanel ID="updatePanel" runat="server" UpdateMode="Conditional" Visible="true" RenderMode="Inline">
<ContentTemplate>
<asp:DropDownList ID="ddlCommandAssign" runat="server" AutoPostBack="true">
</asp:DropDownList>
[code]....
For debugging purposes, I want it to fail every time.It doesn't seem to be executing the behind code at all. For debugging, I added the line response.redirect("dummy.html") ... which never gets called, which also indicates (I think) that the validator never gets called.
There is something strange going on in my VB 2005 program that I don't understand.. I have a form that has several tab pages. Each page has one or more DataGridView controls. When a user selects an item on one DataGridView , I want to deselect anything currently selected on any other DataGridView on that tab page. The only thing that should then be selected is the item I clicked on in the current DataGridView .
I created the following code (note there is a CellContentClick handler for each DataGridView control and there are DeselectAll... and RefreshAll... subroutines for each tab page).
It's fairly straightforward. But notice where I placed the XXX NOTE comment below. If I place a breakpoint there, run the program and click on various cells in various grids, and then click on the specified grid cell, I can create situations where the breakpoint is never reached! Thus, I don't turn off the selection in other grids.
How can this be? Is there some setting for DataGridView controls that I've inadvertently set incorrectly (without my listing them all here)? Or is there some bug in VB I'm unaware of? The "DeselectAll" subroutine merely iterates over all DataGridView controls in the current tab page (except for the current DataGridView) and calls ClearSelection on each such grid. RefreshAll calls Refresh on every DataGridView on the current tab page.

I have a form in Visual Basic that is adding a row of data to an Access Database.What will happen (or rather what I would like to happen) is that when the form is created, a row will be added to said database. Once that row is added, I want to have another form open (called NewWindowA) which will pull information on that database that is related to the ID of the row that was created from the first form.I know that in NewWindowA I need to have the form load the values on Load. But my question is: How do you pass a value to a new window that's invoked by some action?

I am having difficulties populating a checkedlistbox (CLB) based on the selection(s) made in another. It should also be noted that I have a "Select All" checkbox at the top that checks/unchecks all of the items in the first CLB. Here's the code:
[Code]...
The first CLB is populated with an arraylist of values on the button click event. Based on whatever is checked in the first CLB, corresponding values from an arraylist of structures should fill the second CLB.The following code partially works until the "Select All" checkbox is clicked at which point if other values have been selected before "Select All" is checked, the second CLB is filled with the correct number of corresponding values BUT only those of the most recently selected item of the first CLB instead of all of corresponding values of all of the items that were not already selected.

View 2 RepliesI am opening frmB (variable for FormB - the actual form) from frmA. From btn1 I open frmB like this:
frmB = New FormB()
frmB.Show()
From btn2 (frmB is already open) I bring frmB to the front from behind frmA:
FormB.Show()
FormB.BringToFront().
No problem so far. Now I need to pass an arg to frmB. This is where I am having the problem.
from btn1 (in frmA) I do this:
frmB = New FormB(myArg) '--pass myArg to constructor of FormB -- no problem here
frmB.Show()
then from btn2 -- this is where I have the problem
FormB.Show()
FormB.BringToFront()
I tried placing myArg in FormB.Show(myArg) but that did not fix the problem. What is the correct way to pass myArg to FormB (frmB) in this scenario? Do I need to share FormB or frmB? How do I do this? "frmB" is frmA level variable.
