So I am trying to get the screen size without the taskbar, and through reading around I found that the only reliable way was to get the "working area" of the screen (Especially since I might be using multiple screens.), then subtract it from the screen size
Now, my issue is that the working area I am getting is equal to the screen size, which means it is not showing my the actual working area. I have tried some different solutions, and the codes are straight forward.
Dim workingArea = My.Computer.Screen.WorkingArea
This would give me back 1920x1080 which is the same as my resolution. I am not using an auto hide taskbar, and I am not sure what's the issue with this, and/or if there is a better way to do what I am trying to do.
Edit: I have tried to use the DPI aware as per the last comment (following the steps in Using SetWindowPos with multiple monitors)
I am quite confused why I am not getting the correct number here, any feedback is appreciated.
Edit2:I have tested this code itself in another PC and it was a similar result, I will attempt to install an older version/newer version of visual studio or another .net version, however the issue is still illogical, and no solutions seem to be working (with one or more screens having the exact same feedback.)
Edit3: The task bar does not hide, testing the numbers still shows the same regardless of the number of screens, different resolutions were the same as well.

I have written an app that makes extensive use of custom right-click menus on an Access form. The code works great and the user loves it, but lately I am having trouble making it work properly.
In earlier versions of Access it worked well, but newer version seem much more limited in how many items can be put in such menus. The documentation is silent on the matter, and nobody in any newsgroup has had any useful ideas, but I regularly get random error about stack space, out of memory, and general lockups when populating the menus. Doing a C&R used to help, but now even that is not enough, and some menus I can no longer populate at all.
I tried building an app that just built menus until it crashed, to get some idea of what the limits may be, and I am well below what that indicated, but the experimental app had nothing else, while the real app has a great deal else.
Is there any information on how much stuff can be put into these menus, and what the menus share space with? There may be something I can do another way to make more room for the menus. I tried moving all code out of the form, leaving only event stubs that called routines in standard code modules, but that did not help.
And how are they stored/activated? The app is MUCH slower to load when it has these menus, even though no code is running on start-up.
********** Edited to add this:
I use VBA to create a menu, like this:
Application.CommandBars.Add "RCStat", msoBarPopup, False, False
then add it to a control. like this:
Application.CommandBars.cboStat.ShortcutMenuBar = "RCStat"
I add controls (only popups and buttons) like this:
Application.CommandBars.Controls.Add(type:=msoControlPopup)
Application.CommandBars.Controls.Add(type:=msoControlButton, Parameter:="StatKod = 77")
It runs perfectly and the menu items work exactly as expected, except that it bombs after adding some number of controls. It doesn't seem to matter where I add them, just the total number of added controls hits some undefined threshold, and the app crashes.
I got the original code from Getz, Litwin and Gilbert, 2000 edition. Back then, it worked great. But as the versions advance and the app accumulates data, it is becoming less and less functional. However, there are only around 10,000 records, and the app itself is less than 100MB - nowhere close to any of Access's upper size limits.
Pete,
I've done quite a bit of work with shortcut menus, and created the Access Shortcut Tool about 5 years ago, but have never attempted a menu with so many controls although some have 3 or 4 levels.
I am not aware of any restrictions on the number of elements in the commandbars collection, but I find that shortcut menus with too many options, like lists and combo boxes with too many items, are difficult for users to navigate. I generally break these up into segments and use buttons in the form header to display the appropriate menu. Sorry I'm unable to provide anything more helpful.

We have a commercial product, Total Access Components, that includes as one of its 30 components a right click popup menu that can include icons and font styles.
Here's the info for the popup menu control: https://fmsinc.com/MicrosoftAccess/controls/components/popup-menu/
There's a free trial if you want to try it.
I'm using a really nice third party circular progress bar (installed via nuget & v2.5.6403.13419) Found here that has no border property but it still insists on displaying a top and left hand border artifact as per my attached screenshot (from VS 2017) although in all the examples this is not the case. I can't figure out why this should be and have experimented with every setting I think may cause it to no avail. I've set the forms paint to
e.Graphics.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.AntiAlias
but no difference and I've run out of ideas and my searches for anything similar have turned up nothing. Can anyone suggest anything please?
I've been working on a dashboard for the past several months in Excel 2010 and was nearing completion when we were upgraded to Excel 2013. I have experienced one issue that I'm completely stumped on...
I built a simple UI for the dashboard utilizing the first several rows of each sheet. Essentially, each sub-menu is hidden in a different row and only the appropriate rows are visible at any time. Is also allows the user to toggle on/off the various menus in/out of view without using a userform.
Prior to upgrading to 2013, it was very snappy and responsive, taking around 0.05 seconds each time a change was made in the UI. However, after migrating to Excel 2013 the UI is very sluggish. At first I thought it was a screenupdating issue because the screen was updating in bits and pieces - the labels, hidden rows, background color, etc would come in chunks, instead of all at once. I've ruled that out as a possibility.
I also tried disabling all of the annoying new animations that are baked into 2013. I tried all of the different methods I saw out there online - disabling the hardware graphics acceleration, turning off unnecessary animations in the ease of access center, etc. That too seems to have no effect.
After a full day of troubleshooting, I've noticed a sheet with just the UI and nothing else runs just as snappy as before. It's only when there are objects on the worksheet that things go wrong. From what I can tell, shapes and text boxes seem to have no effect on performance. Labels, both form control and Active X, seem to be the culprit.
I've noticed that the little bits of code I have for the UI continue to run at the same speed, but the screen will continue to change even after the procedure has run. This also totally perplexes me. I have tried changing the property from Move and Size with Cell to Free Floating and neither seems to make any difference. I've also tried changing things like Print Object, Locked, etc.
I'm totally stumped as to how to resolve this issue. It's definitely something endemic to 2013 as the exact same file runs without issue on 2010. If anyone has any suggestions they would be greatly appreciated.
UPDATE: Here is a link to a sample file highlighting the issue. Both work fine when tested on 2010.

Granted this is a stretch, but a little bit of research tells me that Excel 2013 has suffered a number of problems with ActiveX controls. There were several patches Microsoft has released, so I recommend you install them first and make sure your copy of Excel 2013 is completely up to date.

If this does not fix the problem, please let me know and I will remove this answer.
All, thanks for your help. I finally solved the issue I was having. I isolated the problem to Form Controls or ActiveX controls being visible at the time the code is run. I'm not sure why but the presence of either creates an issue. However, hiding all shapes prior to running the code and then unhiding them after resolves the issue. I did notice, however, this solution only works if the code does NOT turn screenupdating off prior to execution. I will post an updated file later when I have access to dropbox.
EDIT: I realized that I didn't tag this properly - I should have included vb.net as a tag, on the grounds that there could be a code based solution. Note, that no changes to the resolution are made in my source code.
UPDATE: When the program starts execution, the left coordinate for each PictureBox is multiplied by ~0.376, whilst the top coordinate for each PictureBox.Top is multiplied by ~0.418 . This "down-scaling" applies to all picture boxes. The source code I have is incredibly rudimentary and cannot be responsible for this. I also looked at another project and I still face the same error. A simple but poor fix would be to divide each coordinate by the corresponding values mentioned above.
In order to show you the issue I'm facing, please look at the images below. Compare this image, where each PictureBox (i.e. a snake, set of arrows, etc.) has been placed so that they line up with a feature of the background image:
To this image, where the PictureBox elements are bunched together. Their positions have been "down-scaled" closer to the origin of the form (note that all the elements are transforming horizontally during runtime, which is why the elements are in the top right corner):
In the solution I was given (developed in VS 2010 I believe), the position of each PictureBox goes beyond the background image as shown:
It is clear that each picture box has been placed in an organized fashion. During execution, each PictureBox goes to it's intended position (i.e. lines up appropriately with the background image).
Obviously, the original developer of the solution I was given would have not faced the problem I am. The fact that the solution works properly during runtime indicates some kind of error with my instance(s) of VB. Does anyone know of any solutions?
I've came across this question which asks how to change the default resolution for a Windows 8 App and this question which asks why some applications appear differently on different machines, but they pose no clear solutions. I would appreciate any help, since it's holding me back from critical work I must do. Thank you in advance!
I feel a little silly now - I started carrying out a bit more research on VB forms and came came across this Microsoft documentation on form scaling. Realizing that my issue may have been caused by having this scaling automatically carried out, I then found the AutoScaleMode property of my form and changed it from Font to None, which resolved my problem.
I have a Windows Phone 7 application and I regularly see "weird" UI glitches that take me AGES to debug. It's a range of issues like controls appearing to have extra margin, scrollbars not appearing, animations looking really glitchy, entire page scrolled down, combobox items offset, etc. etc.
I'm happy to admit it might be me - but how to you debug UI errors like this? I know there's Silverlight Spy for the PC Silverlight Apps. Is there anything like this for Windows Phone 7?
Any debugging tips v much appreciated.
I have found that it is a good idea to start with Windows Phone 7 Design Templates, adopt a version control system right from day one of the project and to edit the XAML, use Expression Blend. The Visual Studio is great for writing code, but, to harness the real power of the tools, Expression Blend is the best to style your application.

Here are some tips:
Many people have issues with the emulator due to their graphics card.
Things like slow animations and ui glitches are very common.
Check that your graphics card is Direct X 10.1 at least and that your Driver
Model is WDDM 1.1
Make sure you have the latest drivers.
Windows 7 has less issues with the emulator than Vista
Make sure you have the latest tools, get the RTM release from the website.
In the RTM release, the frame rate counters are displayed by default in a vertical bar on the left, you should monitor these to check for performance issues
Here are a couple of things which I normally do... none of them are real smart, but sharing nevertheless.
Deploy it after every 2-3 controls that you add and ensure things are correctly laying out.
If by chance it doesn't work the way I am expecting it to, I have a parallel Silverlight 3 project running in which I typically paste the XAML and see if it works fine.
After that, I typically check it out as a Silverlight project since even I am not sure of any tools available for Win Phone 7.
I have favorited this question and I hope someone points us to something more interesting.
There's a lot you can checkout with Blend as Indy suggests. This is really good advice.
Regarding some of your specific issues these aren't necessarily glitches. I'll comment on a couple that stand out.
Extra margin - this and padding are built into the metro controls by design. Again, in blend you can dig into this by retemplating the control and changing properties of objects within the control.
The procedure for this is rclick the control, edit template, edit a copy. Then you can look at the different states and objects and change things as suits. While doing this please keep in mind the App Certification Requirements and UI Design Guidelines.
Regarding scrollbars, these are by design hidden until you start scrolling. You can control their availability with Horizontal/VerticalScrollBarVisibility on relevant controls (or on the ScrollViewer embedded in some controls - again retemplate in blend).
Combobox isn't metro themed so is going to struggle in the fitting in department, but there are posts around where people have done work on this. ListPicker is a better fit imo from the Windows Phone Toolkit released with the RTM tools.
If you can't see any obvious causes for the glitches in your code the first thing I would recommend is to actually test your app on a real device. Somethings - particularly animated objects -don't always look exactly the same when you run them on a device.
I thought I had a animation glitch in one of my apps but it only appears in the emulator. When I run on an actual device I don't see it.
Of course this doesn't help you if you can't get a phone to test it on yet, but before you potentially waste hours trying to debug a problem you might not have I would work on the rest of the app until such time as you can test the app on a real phone.
The same goes for anyone creating animations - don't waste time perfecting animations in the emulator. The timings will almost certainly be different on the actual device, so wait till you have one to test on.
