VS 2005 : Showing Different Usercontrols In A Container One A Time?
Mar 26, 2009I want to be able to show a different usercontrol in a single container depending on a criteria, something like
Quote:
if a = 1 then
show usercontrol1
else if a = 2 then
show usercontrol2
etc
I could add all of them at a time and just tweak their visibility per each case but is that the best method for such task?
VS 2008 Adding ToolStrips To A Container During Design-time (via Collection Editor)
Oct 28, 2009I am trying to extend the functionality of the ToolStripPanel control (which is a panel hosting ToolStrips that can be moved during design-time, as I'm sure you know).One thing I wanted to add was a 'ToolStrips' property, which would be a collection of ToolStrips the user can edit via the collection editor in the designer. So instead of manually placing ToolStrips on the ToolStripPanel via the toolbox, the user can just use the property to add/remove (or even edit) them. This is of course similar to how you add/remove/edit TabPages in a TabControl.So, I came up with this code, which I have used successfully in the past for other controls:
Public Class cToolStripPanel
Inherits ToolStripPanel
Private _ToolStrips As New ToolStripCollection(Me)[CODE]....
The cToolStripPanel control inherits the ToolStripPanel control and adds the ToolStrips property, which is of type ToolStripCollection. That class, in turn, inherits the Collection(Of ToolStrip). In the InsertItem method, I add the 'item' ToolStrip to the cToolStripPanel. Of course I also need to override the RemoveItem / ClearItems methods but that's for another time.I am 100% sure that this code should works, at least for other controls. If you replace ToolStrip with Button (for example), I can add buttons via the property during design-time just fine, exactly the way I want it.But it seems that ToolStrips are special. When I try to Add a toolstrip (via the collection editor Add button), a null reference exception occurs. I've been trying to debug this all day and I've finally come up with a possible candidate for the problem... (I've actually used design-time debugging for the first time ever, which was pretty cool, and which showed me that the InsertItem method is not run!)
I think the problem is that the collection editor cannot create a new instance of the ToolStrip class. I can remember when trying to inherit from the ToolStrip, I was forced to add a constructor, because the ToolStrip "has more than one constructor that can be called with no arguments".Perhaps this is causing my problem? Do I (and if yes, how?) have to somehow control the creation of a new instance of the ToolStrip? Or am I completely off track and that is not what is causing the problem? I'm sure that it's a problem with the ToolStrip class, since I can use the exact same method with other controls just fine. It's only when I change the type to ToolStrip that it starts getting angry at me....
Container Controls Access Controls At Design Time?
May 13, 2009I've been building controls for many years professionally and personally, but even back in VB6 days I just could not work this out. After all this time I remembered about it again.If I create a usercontrol/containercontrol and add one or more controls to the controls surface, I just cannot figure out how to access the controls at design time.

View 7 RepliesDid Container Change In 4.0?
Jul 27, 2010This is more of a ASP.NET question, but we are using VB.NET so it might be relevant. We just recently upgraded an ASP.NET 1.1 project to 4.0.Once we started running through the app to regression test it, we found that (consistently) if we made a call like DataBinder.Eval(Container, "PropertyName") from a User Control, ASP.NET complained that it could not find the PropertyName on the page.
PropertyName *does* exist on the User Control, but not on the page.This worked up until we upgraded to 4.0.The fix we found was instead of using "Container", we used "Me" to reference the control that the code was being called on.

View 3 RepliesSet Pixel In Some Container?
Feb 2, 2012VB 6.0 had a Set Pixel function, which is not available in VB.net. using a draw ellipse function with parameters specifying a circle one pixel in diameter.The above is painfully slow.I have been drawing graphics in a Bit Map using a Set Pixel function & then copying the entire graphic from Bit Map to a Picture Box. This results in nothing seeming to happen for several seconds & then the entire graphic is displayed in the Picture Box.
The above does the job, but it would be nice to display the graphic as it is being generated pixel by pixel, which was possible using VB 6.0, Might there be a Windows 7 API which would set a pixel? Might Microsoft be considering a Set Pixel function for Picture Box graphics?

View 3 RepliesC# - Convert A Date And Time To UTC Time Based On The Time Zone Of The User?
Sep 6, 2009I have an ASP.NET application with a SQL Server back end. I am storing all my dates in UTC format and doing the appropriate conversions to the local time zone of the browser viewing it. One of the pages asks for a start date and end date (no times).
I am taking the start date and setting the time to 00:00:00 hours (midnight) and I'm taking the End time and adding a time of 23:59:59, so that the date range covers the whole day. Now what I'm trying to do is do a SQL query to do a search for records in this date range. The problem is, the data in SQL is in UTC time and the user is typing their dates and times in their local date and times. My quickest solution was to convert the date and time to UTC, then search the records. However, by doing this, I am to believe ASP.NET converts the given time and date to UTC based on the server time zone. How can I convert a date and time to UTC time based on the time zone of the user?

Keep MDI Child Inside MDI Container?
Jun 22, 2010In my program, I want the user to be able to move an MDI child window anywhere inside the MDI container but I need it to be kept completely inside the container boundary. For example, the upper left corner should never be at a location less than 0,0 when moved left or up. Currently, if I slide the child window too far left, it extends outside of the MDI container window and the MDI container shows the bottom scroll bar.
Is there a way to prevent the child window from moving outside of the boundaries of the container window? I tried adding code to the .move (see below) so that if the new location was less than 0,0 then it reset it to 0,0 but then the child window controls flicker as the window is moved beyond 0,0 and the logic moves it back to 0,0. It appears that even though the code changes the location to 0,0 and the window shows the child moved to 0,0, when the mouse moves again, the window jump back to its unmoved location.
Private Sub MyForm_Move(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Move
