AddHandler Event Seems To Cause The Themes' Css File To Not Be Applied?
Feb 1, 2009
I am currently writing a website for a company to display their products to their customers. One of the things I am putting into it is the ability to add news items onto the homepage, only part of the admin side of the site.
I have managed to extract some news items from the database, and display them dynamically in a Web User Control which I have added to Default.aspx. I have managed to add buttons for "Update" with events. The problem is that, on clicking one of these update buttons, the page reloads with the theme applied (as it should), but the css files from the theme do not apply - the body text is bigger than it should be and changes back to the default font. I know the skin files apply as I have tried setting all button backgrounds to black by default. The css files seem to apply to any text which is generated from clicking an update button (I have it so it writes the title of the news item for the button that was clicked. This text is the size and font it should be). I have spent HOURS trying to work out why this is happening, with loads of Googling but no success. It is almost as if the theme is being applied between the PageLoad event and the ButtonClick event, but the skin files would say otherwise. Does anyone know why this is?

I have a form with about 40 checkboxes. Once a checkbox is checked, the div control's property should be changed from "none" to "block" or vice versa. I don't get an error, but the checkedchanged event isn't handled. Here is the markup:
<tr>
<td class="sectionSubHeader lightgrey">
<asp:CheckBox ID="chkbxCOMAEFund" AutoPostBack="true" runat="server" />[code]....

I'm getting a bit more fluent in VB.Net, but am still a bit green around the edges in certain aspects. I'm creating custom controls, and am starting to rely heavily on AddHandlers to manage them.Until recently, I didn't realize that you can add multiple event handlers for the same control and same address
[code]...
The above code would create 10,000 copies of the same event, and if I would click on combobutton1, the event would fire 10,000 times. I only need to fire the event once, but sometimes my code is a bit circular, and there may be an instance where two or more addhandlers are designated for a given control and address. Is there a way to have a loop on my custom dispose event where it would look something like:
[code]...
Or better yet, remove all events from a control(On a side note, is there any way in the debug mode to see all the active events attached to a control?)

Perhaps surprisingly I haven't added an event handler programatically before and I'm having trouble getting my head around AddHandler.I am creating a series of DataGridView controls in a loop and want to subscribe to the CellFormatting event on each of them.The event handler signature is as follows;Private Sub ConfigureRows(ByVal sender As System.Object, yVal e As System.Windows.Forms.DataGridViewCellFormattingEventArgs)This works fine when I enter it in the visual editor properties box but I can't figure out how to give it the correct arguments using AddHandler.

I am playing around with Drag and Drop, and I am having an issue with AddHandler. I am creating labels and displaying them on a form. Before I add each label to the form, I add 2 event handlers (DragEnter and DragLeave). When I run the code, it hits the first event handler (DragEnter), but doesn't hit the second event handler (DragLeave). Either I have coded something wrong, or the second handler is not being added.
Here is my code (note this is just something Im playing around with for learning):
Public Class Form1
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

I have a module that handles adding controls and populating values on a form. One of the controls is a button (there can be many) which acts as a lookup. For some reason, when I click the Button, it winds up in the btnLookup_Click event and displays the various messages, but it does not update the label (labLookup) text on the form. Am I missing something?

I have a vb .net program on visual studio 2005. I modified my code for a bug fix. When I am rebuilding and running the application, it shows me the old version of my program, ie, the new changes are not taken effect. To test more, I changed a Label box text and tried to rebuild the program. The program shown me the screen with the old label text. The change was not affected. I tryed to save the application, close, reopen , unfortunately the same effect. Then I copied the project folder to my other laptop to see if visual studio had anything wrong. But then there also I am facing the same problem.

I wrote a small app we use on our computer to keep them running optimally and do some utility things (delete temp files, defrag drives, clean registry, backup my docs to the server, etc). One of the options I ahve in there is "Reset Windows to Defaults" and the objective was to setup windows how we normally would set them up before we give them to our users. So if a user messes with all his/her settings we can click this button and reset it all back. So far it resets IE settings, changes Window Explorer views, puts all the default icons on the desktop and turns off desktop cleanup, etc. Well one of the last things I want to do is change to the default Windows XP theme and apply it. After a lot of searching the internet I found this:
[Code]...
It does reset colors and stuff back to the theme. The problem is if a user has "Windows Classic" set and this is run it does apply the theme.....mostly. Things like dialog boxes stay in classic while the menu structure and desktop go the XP style. If you go into display properties it still shows "Windows Classic" but under Appearance it shows "Windows XP" which leads me to believe even though this function is for themes its actually just applying the appearance and not actually setting the theme.

I have the [B] [I] [U] buttons and they work to a point but here is the problem I'm having.In MS Word,I can Hilight text and select Bold and it bolds the text, I can then select Italic and while leaving it bold, it Italicizes it.I can then click the bold button again and it will remove the bold but leave the selected text Italicized. I can't figure out how to get this action to work.I know I can OR the styles to apply multiple styles to the text but I don't know how to remove a style while maintaining any others applied.Here's a section of code that I'm messing with.[code]....btw, I am using for the comments so that the code is easier to read.I have tried (in this specific segment) newFontStyle = currentFont.Style And Not FontStyle.Bold

Consider this scenario:
Class MyClass
Property SubProp1
End Property
[code]....
Next, I put an instance of MyButton into a property grid, expand property MC and edit SubProp2.From the type editor for SubProp2, I want to get hold of the attribute applied to property MC.Looking at the context,PropertyDescriptor.ComponentType, we arrive at Type: MyClass.If i look at the attributes applied to MyClass, though, it will only return the attributes applied directly to MyClass, and not the extra attribute applied to the property MC.
