Data Grid In Another Open Form Be Refreshed By Calling A Sub Routine?
May 7, 2012
Can a data grid in another open form be refreshed by calling a sub routine? This app has a form with 2 data grids. When the user double click on one of the grids another form is opened that shows data details. After the user changes the details the user clicks a save button. We have placed this code in the Closing event of the the details form.
Private Sub FormParents_FormClosing(sender As System.Object, e As System.Windows.Forms.FormClosingEventArgs) Handles MyBase.FormClosing
FormParentsAndStudents.RefreshDataGrids()
End Sub
[Code]...
Can you tell us what additional coding is needed to refresh this data or if we are using the incorrect place to call this code from within the details form?
I have datagrid in which the 0th column has ID. What i want is while clicking on the datagrid the id of the particular row has to be load in the variable in the second form.

I have a panel2 inside a split container that has several user controls loaded into it. Panel 1 has an exit button and I want to call one of the sub routines that is in one of the user controls loaded into Panel2.
Private Sub btnExit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExit.Click Dim dialogMessage As DialogResult Dim a As New ucTimeTracker[code]......
This line is giving me trouble "ucTimeTracker.autoWriteFileOnExit()"
I am getting (reference to non-shared member requires an object reference).Basically I want the exit button on frmMain. SplitContainer. Panel1 to call autoWriteFileOnExit() on the user control named ucTimeTracker that is loaded into splitContainer.Panel2
Whene i open a form with a Checkbox Column into a Grid, i have no problem.But when i close the form, and directly open it again, i have a error.i use this code

I have made a little programme where the user can put in a name to search for a contact.The matches then fill a Datagrid and the user can then choose the one they want and the programm then opens the contact form (from outlook client)The Contact form opens ok, and it brings up the correct contact. If the user then selects the option to "Email" from that from I then get the error message"A Dialog is open" etc...
My code is as follows
Sub GetContact() Dim objOutlook As Outlook.Application Dim objNS As Outlook.NameSpace
[code]....
It seems to be due to Outlook being open or opening?
I have a MDI app that I am creating. It, of course, will have multiple MDI child forms. In each child form, I have an options button so that each child form can have it's own set of options. When I click the options button it opens an Options form. This options form is not an MDIChild.
I have a class that contains the child forms options. I pass this class to the options form using a constructor. This is how I call the options form:
Dim dlgPatternOptions As dlgOptions = New dlgOptions(thisPatternOptions) thisPatternOptions is the class that I am passing to the Options Form.
This works fine and the options form does populate the options correctly. The Options form constructor is this:
Public Sub New(ByRef thePatternOptions As CanvasOptions) Me.InitializeComponent() Me.txtCanvasWidth.Text = thePatternOptions.CanvasWidth.ToString Me.txtCanvasHeight.Text = thePatternOptions.CanvasWidth.ToString End Sub
I change the options in the options form. How can I get those changes back to the calling form? Do I need to somehow pass a handle of the calling form to the constructor to get the changed values back to the calling form? Is there some way to pass a handle to the options form so that changes made to options will be pushed back to the calling form?

I am trying to sort a form datagrid alphabetically by the column titled Name. Here is code I am trying. This is my first attemp at programming other than VBA.Public Class Agents

I'd like to take information from a text file I 've created so as each line in the file corresponds to one cell in a row in a grid using DataGridView. I'm having trouble doing that.[code]....
I am using sockets to send message between computers. I send the messages alright. What I want is when the message "x0x" comes, the client must be closed within 5 minutes. Teh admin can cancel the request by sending message "-xx" as well. The routine that checks for incoming connections and accepts messages uses WHILE TRUE...END WHILE since it must always listen. Once I get a message, I need to fire a timer control or other that fires within 5 minutes. But the program cant leave the WHILE TRUE at all. If i exit it early, the timer fires and the program does get exit. How do I fire the timer or other routine while still the WHILE TRUE routine checks for incomin connections and messages?
is there any way to reference a particular code routine in VB.net external to the current loop/routine?Example:
If Var01 < 5 [Routine A] Else [Routine B] End If
where Routine A and Routine B are code sequences at the end of the entire program -- such as outside of the current sub or class? The idea would be to reference an otherwise repetitive code.
This is a VB .NET application where we are showing the output of a SQL statement in a Datagrid view. using .NET 2005.We need to get the seperators of the headers on the grid control to be the same colors as the GridColor on the form. See the picture below:We've tried looking through all of the properties of the DataGridView control, and found some interesting things that looked promising such as the DataGridViewAdvancedHeaderStyle, and DataGridViewHeaderBorderStyle, but none of it seems to allow you to change the colors on it.Does anyone know how to do this without remaking the entire thing with a GDI+ control?
I have a small program which draws some lines with a method called: Drawlines But Now I want to call this method in the load form routine. So if the form is loaded the lines should be drawn in the picturebox. But is this possible or should the form first be loaded completely before you can call methods in that same form?

I have the below code that i am trying to have two datagrids with a grid splityter in the middle. The split seems to be working fine but the issue i am having is when I populate the datagrid it is growing in height and changing the splitter instead of leaving the height alone and adding scroll bars.
What simple thing am I overlooking? <Grid x:Name="gdHistory" Grid.Column="0" Grid.Row="2" > <Grid.RowDefinitions>
I have a sub routine where I pull in information from a database. I want to use variables from this sub routine in another sub routine. I tried making everything public but it doesn't want to be friendly and share.
Dim strEmail as String Public Sub readDB() strEmail = "whatever@doohikcy.com"
[Code]....
The readDB would read the database and set the variables and do whatever it needs to do. Then when they submit the form it would e-mail the form to whatever the email address was.
