Design Time Changes Not Affecting At Runtime

.net - Images On A TabControl Show At Design Time But Not At Runtime?

May 16, 2012I have a small dataset which has most of its schema defined at design time, but I add a few columns to one of its tables at runtime. My problem is how do I reset those changes? he dataset is not linked to any datasource. It just has its own table which I "manually" populate. The static columns have been added to the datatable at design time. However, I add a few columns as runtime based on a list of categories. Like this:
[Code]....
The dataset is used in a small dialog that pops up within my application. I add the dynamic columns when the dialog is opened by using the Load event. Everything works great the first time. But if you close the dialog and reopen it, there are problems. My startup routine tries adding the dynamic columns again, but an error is thrown saying the column already exists. I have tried a lot of things and did some reading but I can't figure out a way to reset the dataset when the dialog is closed. The only solution is to close the whole application and reopen it. I have tried the following in the Leave event of the dialog form:

View 2 RepliesVS 2008 : SQL Query - Works At Design Time But Not Runtime?
Aug 16, 2010I've created an SQL Query using the query builder. In the query builder, you can test the query by clicking the button "Execute Query", and entering the desired values in the parameter fields.
My query returns the correct results when I do this, but when I seemingly pass the same values at runtime, I get 0 records returned.The query is designed such that you can pass nulls if you don't wish to filter data by that particular parameter.
SQL Query:
SELECT ID, UPC, Quantity, Manufacturer, Style, Color, Size, Category, DateReceived, Cost, OriginalRetail, Retail, LocationID
FROM Inventory
WHERE (UPC = @UPC OR
[code]....
In the query builder "Execute Query" dialog, I enter a value I know that the db contains in the "Size" field, "1/1/1900" & "1/1/2199" in Dates A & B, respectively, and nulls for all other fields. This returns 1 record, which is just as I expected. It works correctly.But when I pass the same values into the method created by the designer, I get 0 records returned. I can't figure out where the problem lies. Even if I enter nulls for all fields other than the dates, it returns 0. This tells me that the dates are causing the problem, but I can't figure out why, because I'm passing strings equivalent to what I entered in the query builder.
Setting Background Both At Design Time And Then Runtime - Program Just Closes

.net - Label Control Behaves Differently At Design Time Versus Runtime?
Jul 8, 2009I am creating a custom Label control (by simply Inheriting the standard Label control and re-painting the background and text) because I need a very specific background and border. In the constructor of the control, I set the AutoSize property to false so I can have a standard default size for the new label.
Public Sub New()
/*Set the default size of the control to 75x24*/
Me.Height = 24
[code]....
In my application that uses this control, if I create the new custom label at run time (in code), the AutoSize property stays False, and it works properly.If I try to add the new custom label to my form at design time, it comes in with the AutoSize property set to True, and I have to manually set it to False in the properties window. It's not a huge problem, but I don't understand why the behavior is different.

Create The Report Template At Design-time And Then "binding" A Datatable To It At Runtime?
May 18, 2011New to reports here. Using VB.NET, my application makes use of datatables it creates from a postgresql database.These datatables are defined at runtime rather than design-time, and I would like some way of generating reports from these datatables at runtime as well.

VS 2010 Detect UC Resize At Design Time?
Jan 25, 2011To detect if a usercontrol is being resized in design mode I added this to the UserControl.Designer.vb code....
Protected Overrides Sub OnResize(ByVal e As EventArgs)
If Me.DesignMode Then
' Call a Sub in my UserControl
End If
End Sub
Ok that works, Now do I also need to include MyBase.OnResize(e), if yes then where do I add it?
VS 2010 Can't Populate Listview2 A Second Time
Aug 5, 2011Trying to build a file compare utility to compare two files and visually show the differences in the rows. I have a form with two panels and a listview in each one and a vertical scrollbar in between that will control both listviews.First listview1 inside panel1 will load during form load depending on what is selected on my mainform grid. 2nd Listview2 inside panel2 will load from btn1, this only works once.The compare is done with btn2 and it works okay also.The problem I have is after I have both files loaded up in the form, and I do the compare, everythign works fine but I can't figure out why I can't seem to re-use btn1 to open up another file.It seems to go through during debugging but the listview2 will be blank. Only does this after it was first used.[code]
View 2 RepliesVS 2010 Properties Set During Design-time Are Not Serialized To Designer File
Aug 22, 2011I am creating a UserControl with rich design-time support that should eventually look like the Options window in Visual Studio (or many other applications). Basically a split container, to the left is a TreeView with 'option categories', and each node in the treeview corresponds to a 'panel' to the right with certain options.
Just for terminology, the nodes in the TreeView are OptionsNode objects, the panels (containing the controls that determine the options) are OptionsPanel controls. My UserControl itself is called OptionsView and is the control that contains the treeview as well as a panel that contains the OptionsPanels.
I have some experience in design-time coding, and I have gotten pretty far. The OptionsView control contains a property Panels that returns the ControlCollection of the right side of the split container. The user can add/remove OptionsPanels via this property (and automatically an OptionsNode is created). The property uses a custom CollectionEditor that tells the designer to create instances of type OptionsPanel (instead of just Control which is the usual collection type of ControlCollection). Furthermore, in the CreateInstance method I use the DesignerHost object and its CreateComponent method to create the panels, instead of just creating New OptionsPanel objects. This way the OptionsPanel created is selectable and editable (via property grid) during design-time:
vb.net
Protected Overrides Function CreateInstance(ByVal itemType As System.Type) As Object
If itemType Is GetType(OptionsPanel) Then

VS 2010 Typed Datasets Are Created At Design Time Only And Not Dynamically
Jan 20, 2012In a typical session with the program I'm writing, the user needs to be able to access the data in 1 to 500 (maybe) tables (but always only one table at a time). Up to now I've been creating these single table datasets dynamically, as and when required.I've now come across the distinction between typed and untyped datasets (where typed seems to be the recommended option). It seems, though, that typed datasets are created at design time only and not dynamically. Is this correct? Are all of my dynamically created datasets therefore untyped?

View 1 RepliesHave To Save To See Design Changes At Runtime
Mar 23, 2012Just started with VS2010. (vb)
Coming from VS2005. (i skipped VS2008)
My question is this. Why do I have to hit save before every build in order to see design changes at runtime? Example: I change the text on a button at design time. I click on run and the text does not reflect the change. But if I saved the form before clicking run, than it does. Also like to add VS2010 runs much slower compared to VS2005 running on the same computer. I understand VS2010 can do more, but a lot of times you don't need it to.

How do I get design time to look the same as runtime? Also, they stay light grey in run time if I check Enable XP Styles. Makes me feel better to see the same colors at Design time

Jul 24, 2009I have a question regarding the manipulation of a form at runtime. Let's say I created a simple form in the form designer before runtime containing a couple of buttons, text boxes and labels. While the program is running, I would like to change properties of these controls, while having the ability to move them around, along with the addition of newer controls, say a listbox.
After the form is 're-designed', I would like to save the new settings of my form, in either a database or settings file. Whats the best way to implement this?
