I have some conditionals in my InitializeComponent which affect the layout based on some variables. Unfortunately, it seems like whenever I rebuild my application, this code is reverted back to its previous state. Is this code being regenerated based on the Designer interface? Is there a way to prevent it from doing this?
View 2 RepliesHow to check if a file can be overwritten? Currently I have a problem with files that are
1. In use
2. In a folder where I don't have permissions to edit them
3. Read Only
How to check (check, not overwrite) if a file can be overwritten?
What's happening is that the data is always being overwrited. I mean there is only one row which is constantly being overwrited
Public Class Form1
Private Sub UpdateTable(ByVal Details As String())
Dim DataSet As New LoginServerDataSet
Dim Adapter As New LoginServerDataSetTableAdapters.DetailsTableAdapter
Dim Manager As New LoginServerDataSetTableAdapters.TableAdapterManager

I've rendered a simple rectangle for the background and a bunch of star polygons randomly placed across the form. On the form is a picturebox component which I can move around, but for some reason it overwrites the background and stars when it passes over them. Could someone please explain what is going on there? I've tried performing searches, but have been unsuccessful in finding anything useful.
View 4 Repliesis there a way to keep the settings stored in My.Settings from being "reset" during an upgrade installation? Every time I put out a new build of any application using My.Settings the settings in My.Settings are reset to whatever they are in the visual studio designer.
View 12 RepliesI'm trying to access 2 tables within the same DB in Access 2007, but I have a problem when saving information to one of the tables, I can do it with one table but when I try to save the information to the second table the data gets overwritten, not sure why, because I use the same procedure for both of them, just changing the variables to avoid mixed data, this is the code that I use to connect with the DB and fill the DataSet:
Try
dbProvider = "PROVIDER=Microsoft.ACE.OLEDB.12.0;"
dbSource = "Data Source=.\Almacen.accdb;Jet OleDB:Database Password=Slackware"
[code].....
Again, it works fine when saving info to one table, but using the exact same procedure (with different variables) saves the new data but overwrites the previous information
I'm converting a VB6 forms application to operate in VB2010. When initialising the form using VB2010 I've made use of the New() event with a call to InitializeComponent(), as suggested by the VB2010 Express debug facility. However, when InitializeComponent() is invoked I've noticed that the system runs the TextChanged events for some, but not all, of the components in the form.Can anyone explain what the InitializeComponent() call actually does? and why certain form events are executed whilst others are not?
View 2 RepliesI have make a Tabbed webbrowser. Browser is working fine. but when ever I navigate a page titles of tabs does not changed but overwritten as shown in picture there is on second Tab Text is overwritten. I am using this code for tab title
tabs_bowsers.SelectedTab.Text = CType
(tabs_bowsers.SelectedTab.Controls.Item(0),
ExtendedWebBrowser).DocumentTitle
And this for window title
Me.Text = CType(tabs_bowsers.SelectedTab.Controls.Item(0), ExtendedWebBrowser).DocumentTitle & " - My Browser"
I want to make my tabs to change title as in firefox titles changed, no overwritten.
I am experiencing some trouble with the autogenerated initializecomponent function. Visual Studio insists on initializing a variable like the following, when I drag a usercontrol onto a form:
Dim HierarchyTreeNode1 As NewDelfiLib.HierarchyTreeNode = CType(New System.Windows.Forms.TreeNode(""), ND.HierarchyTreeNode)
I updated one reference in my project and all of the sudden, every time I run my app I get the following error:
Error Stack Trace
The details of where this error occurred are as follows:
Source: frmMyForm.designer.vb

I need to add some code to the EndInit method of a PictureBox control but unfortunately its private and, from what I can gather, I can't shadow it and call base - at least not in VB.Net.What I can do is add a dummy property to my picture box class. The type of the dummy property is simply a class that just implements ISupportInitialize. However, that doesn't work, I need the dummy class to inherit from Control.Is that the minimum requirement?
View 1 RepliesI have a windows form and I created couple user controls, these UserControls are added on the form dynamically, everything works normally,
Just wondering where I should put the coding, should it be inside Form Load Event or after InitializeComponent() call?
Alright so i have a form with alot (ALOT) of controls...many tabs, many listviews, many comboboxes and textboxes, all of which have values which i saveload using a class i made for saving and loading these values from a file.
Loading these values is pretty slow after the form loads. Takes around 3 seconds (i had to create a splashscreen and made it look decent, but it's still not a nice thing to have)
Then today i decided to try something. I opened the designer to initialize component, and i called the LoaderSub (that loads the values for the controls from a file) within initialize component, in a location after all the properties are set but before all the .resumelayout and .performlayout are called. Lo' and behold the form loaded in less than half a second, with the values and all.
However, now everytime i make a change to the form in design view, or even add a handler to some control in code view, the designer redraws and the auto generated code takes out my code from initializecomponent.
I did the googling, and all the results i found for similar cases issues were cases where the person asking the question im going to ask, the answer is "Didn't you read the part that says DO NOT MODIFY?"
Still, as a last attempt, I ask here: is there any way to modify initializecomponent without losing my changes? I just need to call LoaderSub before the layout resumes...if i call it before initialize component, i get null reference exceptions. And if i call it right after initialize component, loading is very slow.
In C# Windows Forms, a user control's InitializeComponent is called from the form's/control's constructor. When I create same scenario in VB.NET I don't get a constructor, and I can't locate a place where InitializeComponent is called.I need to call my code between InitializeComponent and when the control's Load event is raised, preferably still in the control's constructor. How do I do this in VB.NET?
View 2 RepliesThe code generator creates code with references to a component I am using, before it's dependent components (datasets) are initalized. Although I can correct this by editing the form.designer.vb file, everytime I make a change on the form the code is re-generated in the wrong order. Where does VS2008 store information about the order of the components for code generation.
This Runs:

'AppointmentBindingSource
'
Me.AppointmentBindingSource.DataMember = "appointment"
[Code].....
I have made changes to the windows form name from "form1" to "applicant_name" after that it shows this error The designer cannot process the code at line 249: Me.name = "applicant_name" The code within the method 'InitializeComponent' is generated by the designer and should not be manually modified. Please remove any changes and try opening the designer again.when i comment it its started working fine can any one suggest me wat to do and why it is comming
View 3 RepliesI add a mainmenu I have to edit InitializeComponent().I tried to take a shortcut and copy an existing menu and then rename it. Big mistake. If you have done it, do not do it again.Anyone have an idea of how to get me back on track? I have done a rebuild, closed VB etc.

To create splash screen before InitializeComponent, the WithEvents statement for the BackgroundWorker component needs to be moved from the Form's Designer.vb file into the constructor as indicated in the first commented lines of the constructor below.

I need to create an application, which it connects to a IBM AS400 ATL to query LTO3 tapes that have expired and to be returned back to the datacentre. Tapes that have data written on them and not expired will need to be sent to an offsite location. Even if not an application, possible a script to do so.A email from the server will report the tapes require to go offsite and which tapes came be returned which can be overwritten with data again.
