I'm using visual basic 2008. My form is quite simple, with a few buttons and a few labels. Then I added a few more things, such as more buttons or more labels. These new elements show up in the design window, but they don't show when I debug the program. Debugging the program only brings up an older version of the program without the new elements. Screenshots:

Any help with this annoying issue is appreciated.

Currently I would like to program an application gathering forms that are callable with buttons on the side. For this, I am using the latest build of Visual Studio Community. One way I thought of would be to literally put all the form elements (textboxes, lists, etc.) in the application window and only enable them whenever the according button is clicked on. However, if this is the way to do it, I find it quite messy and unpractical, and I'm pretty sure there's another way around.
After some research, I have learned about the MDI layouts, but they don't suit my taste. I would like to keep everything in one single frame.
Could you give me a hand?
I am building my first "real" VB Window Forms Application (I'm a "traditional programmer") and my application has perhaps half a dozen forms.
On execution all of these forms have the Windows 10 visual style (eg: grey on white max/min/close buttons at top right)... except for 1 form, which seems to be rendering in Win XP style (eg: Blue and red button style).
I have checked that "Enable XP Visual Styles" is UNClicked in the Project Properties, but this one form stubbornly refused to change.
I have a number of my forms that also appear in "XP style" in the VS Designer, but execute fine.
I suspect I may have enabled/disabled the "XP Visual Styles" option a couple of times, and perhaps initially created some forms when this was in different states... although I have no idea if this would have been the cause.
I really want this one form to be like all the others...
any ideas please? I am using VB in VS2010 (a bit old, but what I have to hand)
As I am quite new to VB so tell me what I can provide to help..
Many thanks,
David's comment has solved my immediate issue:
The single form appearing differently is indeed using Show() whereas the others are all ShowDialog(). There is no reason for me doing this, so I have changed it.
I am trying to transition into windows app development. However, when i use vs 2015 the designer box is really small. When I drag anything from the toolbox to the designer window it doesn't show up. Everything shows when I run the build but not in the designer. I've been googling and looking through stack but i can't find the answer. Can someone tell me how to get the designer to work.
When working w/ a WinForm project in VS.NET 2015, our team has noticed that the mere act of opening a .VB form in the designer view (default action when double-clicking the file in Solution Explorer) will cause VS to modify many object properties in the "Windows Form Designer generated code" section of the actual .VB code-behind. It seems to be limited to the .Size and .Location properties for sometimes dozens or more of UI objects, always changing their X,Y coords just slightly.
Mind you we don't perform any action to drive this -- simply open the file (obtained from source-control and residing in the local solution/project) in VS.NET's form designer by double-clicking the file in Solution Explorer, and bam -- it has the "unsaved" asterisk and if you save it and compare to source control version you can see the modifications already made.
I couldn't find much on this. Is this a known behavior? Any idea why it does this? Kind of reminds me of the old days w/ MS FrontPage's designer view, and even the early days of ASP.NET in VS which would apply some HTML changes if you opened a WebForm in designer view, until they gave the option to disable that on a later release.
thanks for any input.
UPDATE: this appears to be continuing even with myself as the only editor of the .VB form in designer. various form elements are shifting their position very slightly. Here's a diff screenshot between my last check in and today, and I know I'm the only one editing:
...there are many like that. Always these two properties, always just a few pixels difference.
I don't have an specific answer for this, but since this drove us crazy a bit a few months ago with my team, while working on a WinForms project, I am glad to share my experience!
Every time someone opened any form on VS2015, it would ask other people who has the same solution open at that time to reload the code. We first thought the third party controls (at that time it was both DevExpress and Infragistics) we are using were re-generated on designed initialization - because they tend to do that a lot but then we realised this kept happening on forms that only contains .NET controls.
Now the funny part. This only happened to us on VS2015. We were using VS2013 before, without this annoying problem.
Long story short, then we realized the screens we are using have different DPIs, just like Cody Gray said. I am not absolutely sure if this was the reason, but since we started using TFS, obviously we don't have the problem anymore... Hope this helps somehow lol.
Is there a reason / fix for this weird designer issue (at least, I think it's related to the designer), whereby the controls on the form do not appear as they do in the design window when I debug the application..!
Please see the following two screenshots to demonstrate the problem (note: I have blacked out some of the content of the form, this is not the problem):
Picture 1: Showing how the form appears in the designer view
Picture 2: Showing how the form appears in debug mode
You can clearly see that some of the buttons have moved position on the form.
Note: At first glance, this may appear like a duplicate of: Windows Forms Designer destroys form layout. However, I have not installed any additional tools or components. This is simply a standard "vanilla" build of Visual Studio 2012 on Windows 7 32-bit.
I've also come across this question: UI Controls Overlapping & Fonts Issue in Windows Forms Application. However, I am not using "large fonts", nor am I using any non-standard fonts on my controls (all label and button text is left as default). Still, I can see how this would affect the control positions and will do some more checks in this area.
There's nothing happening within the form's Load method.
I'm also using TFS 2012.
What could be causing this? Is there anything I can do to fix it?
EDIT: I've removed the font property for each label and button control, allowing the system to set the default value. Still no change. Interestingly, if I open the form in design mode, then save it, then close it, then open it again, the buttons have moved... If I do this a few times, the buttons migrate until they're off the form.
OK, I've found the answer, after a bit more fiddling. It seems to be related to the Anchor property on the controls. I made a bunch of changes, testing between each change to see if there was any difference. When I selected all the controls and set the Anchor property to Top, Left, this solved the issue.
I hope this helps someone else at some point!
