Tabpages Position Changed By Itself
Dec 14, 2011
I have added 1 tabcontrol to a form, then I added 8 tabpages to the tabcontrol. I set "Multiline" = True, so that all the 9 tabpages will be distributed evenly in 2 row. The problem I'm facing now is the position of the tabpages will be changed automatically when i clicked the tabpages. I know someone also face this problem before in other forum I searched through Google, however there's no answer posted. Is there anyone know the codes that associated to the position of tabpages so that I can write code to fix the position?

I datagridview and I populate it using a bindingsource. I have the following code in the bindingsources PositionChanged event and it works as I want it to except when I filter the bindingsource.
Private Sub ProductBindingSource_PositionChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ProductBindingSource.PositionChanged
If (Me.ProductBindingSource.Current IsNot Nothing) Then
Dim dr As DataRow = CType(Me.ProductBindingSource.Current, DataRowView).Row
Dim ProductId As Long = CLng(dr.Item(2).ToString)
Dim ResultId As Integer = CInt(dr.Item(0).ToString)
GetReport2(ProductId, ResultId)
End If
End Sub
The scenario is when I click on a row in my datagridview the bindingsources positionchanged event fires and I load a crystal report. Problem is when I filter the bindingsource, even though the first item in the grid is now different the incorrect report is displayed because the bindingsources position hasn't changed.

1.Multiple monitors are connection to one computer and they are extended.
2.My window spans to two monitors (Any window like notepad or settings wizard).
3.We change Visual Style From ON to OFF ( i.e. Changed theme from basic and high contrast to Aero or vice versa)
4.The window which was present on two gets shifted to either primary or secondary monitor.
5.This behavior is ok with normal application but I am developing such application which fails if window moves away.
6.I have added handler to check if user changes theme or visual style using :
AddHandler SystemEvents.UserPreferenceChanged, AddressOf UserPreferenceChangedHandler And in UserPreferenceChangedHandler I have checked if UserPreferenceCategory.VisualStyle changed and if it is changed then I have reset the window position back to old values before theme changed , but still it not reverting back to old position.
7.One strange behavior I observed is, it works if I set break point and step through code , but if I remove it then it's not working.
a. Added handler to catch user preferences changed event.
Private Sub RecordingWindow_Load(sender As Object, e As System.EventArgs) Handles Me.Load
AddHandler SystemEvents.UserPreferenceChanged, AddressOf UserPreferenceChangedHandler
End Sub
b. Copied old position
Protected Overrides Sub WndProc(ByRef m As System.Windows.Forms.Message)
If m.Msg = WM_MOVING Then
' Console.WriteLine("Window is moving")
[code]...
d . This is additional code which i tried instead of WndProc
Private Sub RecordingWindow_LocationChanged(sender As System.Object, e As System.EventArgs) Handles MyBase.LocationChanged
_windowLocBeforThemeChanged = Me.Location
End Sub

even Word Pad, when you scroll your Caret (the I-beam for browsing through text) through the text, in the font combobox, the font of the text you are browsing through will be displayed, and when you scroll your caret through a different font, the font will be changed. If you're confused, look at attatched picture.
I cannot seem to find a caret position changed event on the normal richtextbox control - and if anyone can show me a custom component with this it would help me a huge amount.So my basic question is how can i replicate the formentioned function in my own VB.NET program.No code is necessary just constructive suggestions, or links to other projects would be welcome.

I changed my Username on my computer from i.e. "xxxxxx x xxxxx" to "Dennis"
VB 2008 during a compile gave me the following error: Error reading icon 'C:Usersxxxxxx x xxxxxAppDataRoamingMicrosoftVBExpress9.0VSProjectApplication.ico' -- The system cannot find the path specified.
The file "VSProjectApplication.ico" is in 'C:UsersDennisAppDataRoamingMicrosoftVBExpress9.0'
Somewhere in the VB2008 "configuration" files I believe that I need to manually change the old path to the new path.
I found the old path in the ".suo" file. The ".suo" file is not a text file. How can I edit the .suo file, save it so that it will work?

on my Form I have a DataViewGrid and some textboxes with a save button (they are filled with additional data of the selected row).Save is disabled first, when I change something in the textboxes the save button is enabled.When the user changes a gow in the grid, I want to ask before changing the grid row, if he wants to save (if the button is enabled).I am using RowEnter but this is too late, then the selected row already changed (and my textboxes already got new data)...What event can I use to ask if I should save stuff before the user changes a row?Something like BeforeRowChanging with a chance to cancel changing the row?

I have looking for a tutorial or class that demonstrates more than a trivial example of saving a windows position on closing. The ones I have found don't seem to work on all systems because of:
1. Multiple monitors. (and resolution between those monitors)
2. Toolbar size and position (toolbar is only on the primary monitor, well sometimes)
3. Sometimes the programs dont open on the right monitor they were closed on.
Is there an extensive class or tutorial on all the stuff a programmer needs to get right to have a window size and position persisted between executions?

My UI currently addsabPageGraphs to a TabControlMain dynamically. I now need to present 4 different views of the same data. I want to do something like the following code indicatesbut there is no 'Add()' method for TabPages by which I can add 4 Tabs to an existing TabPage.How would I accomplish this so that under a specific dynamically added TabPage, the User can select any of 4 new TabPages with a different graph to view.
if (!this.tabControlMain.Contains(this.tabPageGraphs))
{
this.tabControlMain.TabPages.Add(this.tabPageGraphs);

Good evening folks, I'm building a program that is threaded. While I can get the thread to work no problem, I can not seem to add pages to my tabcontrol from the class I'm using. Any idea's on what I'm doing wrong?frmMain is loaded first. Then the idea is to load the other tabpages using a separate thread as they take awhile.[code]

I am creating an application which has n numbers of tabpages in three different tabcontrols. some of the tabpages are having graphs and rest of them are having some other calculations based on the data of focused graph tabpage.What i want is when user selects different tabpage containing graph the data of the graph tab should be passed to all the other tabpages using the data to calucate. There is one way which i get is to loop inside all the tabpages,but i want to raise an event from the graph page and handle the event in all the rest of the calculation pages.

I've hit a roadblock and really need help with looping through tabconrol's tabpage's, getting each tabpage's parent name and richtextbox control's text value. I have a ctabcontrol that has ctabpage tabpages, which also have Usercontrol's on the body of each tab. I developed a FindAll to search through each openned tabpage's richtextbox in the mdi parent container form. However, I cannot get the for loop to produce any values for the controls. All values are 0. The richtextbox.text value is empty. I even tried to produce a value with TabControlCollection to no avail, it shows 0 tabs in the collection even though I have 3 tabs open in the mdi parent container. How can I get the actual controls and values from other tabs so I can evaluate them in my Find tabpage functons?

I'm making a custom TabControl duplicate and I can't seem to be able to add controls to its TabPages. In fact, they don't show up at all! I've got code that sets their BackColors to Red, and their DockStyle is set to fill, but they just don't show up. Here's my code for the CustomTabControl:
Public Class CustomTabControl
Inherits Control
Private Const TAB_HEIGHT As Integer = 32

I also have a function that returns ALL tiles on the map and they're X, Y position. How could I find out which one is closest to the position I specify? I can't figure out how to go about it. how to implement it with this. Heres a MADE UP example if what I'm trying to do:
Dim MyPosition as New Position()
MyPosition.X = 400
MyPosition.Y = 400
Dim tList as New List(Of Tile) = MyMap.GetTiles
Now, I can already do the stuff above, but what I need to make is something like this:
tList.GetTileClosestToPosition(MyPosition)

I am trying to show or hide tabpages as per user choice. If user selects gender male then form for male in a tabpage "male" should be displayed and if user selects female then similar next form should be displayed in next tab "female"I tried using
tabControl1.TabPages.Remove(...)
and
tabControl1.TabPages.Add(...)
It adds and removes the tabpages but doing so will loose my controls on tabpages too... i can't see them back. what's the problem here?
