Did vs2008 or vb.net got some of the solution to solve properties setting of the components are same with each other?
Example: like I want to standard the datagridviews' property, each of the datagridviews' property is same with each other. but each time I create the new datagridview. I have to manually set the datagridview 1 by 1.
Most of the apps I write have a base / home form and a few other forms (three of four typically) which pop up in response to controls clicked by the user. I'd like to be able to set some properties to be the same for all the forms in an app; particularly properties like BackColor and FormBorderStyle. Yes, I can manually set the individual properties for each form in the VB IDE, but I'd prefer to be able to have one line of code in the base / home form for each property along with one line for each dependent form which says something to the effect of "use the same property value as the base / home form has". Overall, my objective would be to have one single line of code in the app which, when changed, would apply the changed property to all the forms. For example, a single line which I can change to take the BackColor from Apple to Orange for all the forms ...

View 2 RepliesHow do I get my Form1 to resize so that all the (components) buttons and datagridview, etc. stretch and grow with the screen, but stay in their relative positions? I've tried adding Panels around the elements and docking and anchoring, but, so far no success. Elements scatter and don't hold their position, etc. Is there an easy way to do this?
View 3 RepliesToday I noticed that Visual Studio 2008 always treats a file as if it was a component or a form if this file contains a definition of one.This means that it always opens the designer by default. I think this behavior is very annoying, because a file containing a class that derives from form or control does not have to be an actual form or control and I want to edit the source by default.

I'm stuck trying to figure this one out. I am trying to set a GridViews Column properties by using reflection and the Extended properties off a DataTable.the Code looks something like this
Dim colproperty As PropertyInfo = gv.Columns(col.Ordinal).GetType.GetProperty(key)
Where key = "ItemStyle"
So I get the ItemStyle Property by I'm unsure how to set the next varibel which would be BackColor:Red in the collection i have that key access. This is all text.in the XML the extendedproperty is set like this
msprop:ItemStyle="BackColor:Red"
I can easily set all of the attribues for a gridview using something simular to this but of course gridview columns do not have attributes only properties.
Gridview attribute setting code
Dim nvCollection As PropertyCollection = table.ExtendedProperties
For Each key As String In nvCollection.Keys()
Dim colproperty As PropertyInfo = labelOut.GetType().GetProperty(key)

is there any trick (because I can't think of anything else ! ) to massively set all of the properties , of a user defined class , to their null values ? You see , I have a class called Apartment and it has a lot of properties (it only has properties , no methods or events , if that's important) and those properties are either strings , doubles or integers . I want each time I create a new instance of that class (a new apartment , that is) to automatically set those properties to their null values . That is all of the strings to be equal to "" and all of the numbers to be equal to 0 . Back in VB6 I could rely on VB6 to do this automatically , but now in VB .NET , whenever I create a new instance of a class , all the properties start with the value = Nothing . I know I can define every property in the class module like that : Public MyVariable As String = "" but I'd like to keep them as they are and set their null values directly whenever a new object of that class is created .
View 8 RepliesIn VB6 I would simply retrieve the user font setting from the .ini file, load into variables and then apply to the appropriate control.
text1.fontbold = userfontbold
text1.fontitalic = userfontitalic
text1.fontunderline = userfontunderline
etc.
I'm struggling to understand how to do this vb.net The following code works, but sets all three at one time
Text1.Font = New Font("Courier", 10, FontStyle.Bold Or FontStyle.Italic Or FontStyle.Underline)Since the user can have many different combinations of settings, I would like to be able to add just one of these properties at a time, but can't seem to figure out how to do it.
I have a icon for my application that I set in the project properties window there is a little drop down box to browse to the icon location. While debugging everything is good. Once I build the app and place it on a PC and manually start the app all is good. My app starts with windows and now every time the program goes to start I get an error that the icon cannot be found in the DocumentandSettingUSERNAME folder. So the question is do I have to place my app icon in this folder? In design I have the icon in the binDebug folder and that is were I point to in the Project properties page.
I am using VS 2008 VB.net.
i am writing a VB front end (VS 2008 .NET 3.5) to a data loading program that involves moving the contents of CSV flat files into SQL Server 2005 staging tables. I have had some experience with DTS in SQL 2000 so I decided to use SSIS packages to load the CSV data. Creating the packages in BIDS worked fine for the development environment where I hard-coded the Connections and file paths. The problem arises when I will release this program to 30 different sites that do not have SQL Server admins to help changing the configuration.
I have a SQL table in which I will put all the necessary path information and I can pull that into the VB program on startup. I need to see an example of how I can set the properties from VB once the package is instantiated and opened.Here is an example of where I plan to set those properties and run the packages.
Private Function RunPackages() As Boolean
Try
Dim oApp As New Application
Dim oPackage As New Package
[code]....
Even though I am using a configuration file in the example, I am finding it difficult to edit the configuration files for each site. I see that there are methods and properties exposed for the oPackage instance. However, I can't find a good reference for the Class model to use as a guideline. All the examples expect packages to be run and configured with SQL Server and BIDS. direct manipulation of package properties in VB or C#?I am now considering using the old standby SQL Bulk Insert. It almost appears as if the Data Tasks are just wrappers for the Bulk Insert operation. Furthermore we have several sites still using SQL Server 2000. With the economy the way it is, most of those sites do not want to spend ANY extra money upgrading to SQL 2005 or 2008.
However, having a good resource to learn how to manipulate SSIS packages from the CLR would be very helpful. I have heard that in SQL 2008 things have changed even more. It is maddeneing that once I learn a "new" Microsoft technology it seems to be discarded by MS in their next release in favor of a "better" alternative.
I have a DetailsView which has two fields - one that is visible, one that is not. The first the user fills out, the second I want to auto-populate. Unfortunately, I haven't been able to find a way to set the value in this second invisible field. I've tried adding code like this to the Page_Load:
If Not IsPostBack Then
DetailsView1.DefaultMode = DetailsViewMode.Insert
Dim txt1 As TextBox = DirectCast(DetailsView1.FindControl("Type"), TextBox)
txt1.Text = "administrator"
End If
But this returns an error of "Object reference not set to an instance of an object." Any ideas on how to accomplish this - either using the method above or another method?The hoped for end result is that when a new record is inserted via the DetailsView that this record will include the username (entered by the user) as well as the "type" of "administrator"
I have built a deployment program (vS 2008 Standard Edition) and tried to set the Properties column to a product name and company. I have also tried leaving these blank.

Is there somewhere I can specify exactly the default path for my setup without it adding a subdirectory? What do I edit?
View 2 RepliesPassing data between forms without any public methods or properties on the forms. everything but the "Controller" class, which I would like you furnish. I just changed the title from "Intermediate" to "Beginner" This solution is an example of the Observer Pattern. The "Controller" class is the "observed" class, which in this case means it publishes events.

Public Delegate Sub MessageDelegate(ByVal sender As Object, ByVal e As MessageEventArgs)
Public Class MessageEventArgs : Inherits EventArgs
Public Message As String

The program should initially display Form1, and Form2. Clicking of the button on either form will modify the Title Text of both forms. I think that you will find the final end result to be pretty neat, as it works with any number of open forms not just two. I think asking for the Controller class is easier than asking for the code in the forms. My solution for Controller class has 7 lines of content, 9 lines if you include Class, EndClass. A minimal solution could achieved with only 4 lines of content, but it would a textbook example of bad programming.
I'm making an editor for my app. which allows the user to change properties of the controls including the font.I'm storing the values in a collection but I'm having trouble re-setting the fontstyle from the stored value. I'm storing the font information like so...

is it possible to set a value of an item, for example: a textbox1.text = Empty.String at design time?

the problem i keep having is the window with the options to save the information pops up, not the main window. is there a way to easily fix this? maybe a snippet of code, because the only way i can think of is to scrap the project, start over from scratch adding my main window first, then the others.
