I have a WinForms application (developed in Win 7 64x) with a CheckBox control. I have set the AutoScaleMode property of my form to "None". The form looks fine on my machine.
However, when I send the program to my colleague who is running Windows 8, the CheckBox text appears incomplete. I'm not sure what property of this control is causing this.
I'm not sure what property of this control is causing this.
Well obviously it is the AutoScaleMode property. Or, I suppose more accurately, it is the Size property.
Your colleague's machine has not only different sized controls, but also different sized text. You can see this clearly by comparing the screenshots. The checkbox control's allowed size is too small (not wide enough) to display the entire label, so it gets truncated and all you see are the first two letters of the label.
The solution is rather simple: make the control's area bigger. A better idea would be to let this resizing happen automatically by setting the AutoScaleMode property of your container form to something more sensible, like Text or DPI. This ensures it will not break when the user has a different DPI or font setting than you do on your machine.
Long-term, it is better to design your forms with a fluid layout using TableLayoutPanel or FlowLayoutPanel in conjunction with the Anchor and Dock properties. It is more work than drag-and-drop in the designer, but it produces much better results that scale in all environments.

I have been developing winform applications for a long time and I've never noticed something very simple, almost basic so I went back to the basics, I made a big form with a button on the extreme and I noticed that the size of the form changes completely when run:
design
run
As you can see the form size gets smaller and the button is hidden.
The properties are the default ones AutoSize false and AutoScaleMode Font.
This question is similar to this but unfortunately the answer there is not useful since the recommendation is the default.
Note: This is automatically solved when my notebook gets connected to another display
Below are some steps you can try if one of them can solve your issue:
If the problem occurs only when you connecting with other monitor, try to change the settings when connecting, does this happens to other PCs too? Or try to use another PC or install a VM (Virtual Machine) to run it there.
Check your DPI settings, for example in Windows 7, is that Smaller - 100% (default), or Medium - 125%, or Larger - 150%?
Try to set Form's property AutoScaleMode to Dpi or Font for each case.
If the problem still persists, try to create the sample form with the help from Creating a DPI-Aware Application.
I once tried to use FlowLayoutPanel control to arrange some identical elements such as buttons, pictureboxes. If possible, try to use it when applicable.
Last one, try WPF instead, it seems complicated at first, but you will get used to it soon and find out interesting things that Winforms doesn't have. You can arrange control to a grid (similar to a table), then put your controls to each cell with no problem. My suggestion if you plan to learn from ABC: WPF Tutorial.
Leave comment if you need more help, I will come back to see if any further I can provide. Because I've come into this obstacle when creating an app before :)
Set button "Anchor" (Right*, bottom) in property window
I have written a program in C# (Visual Studio) which makes use of multiple forms. The problem occurs whenever the program is run on a different computer which has a different screen resolution. The contents of the form do not fit into the form whenever the program is run on a computer with a smaller screen resolution. What can I do to make the CONTENTS of the form resize accordingly, depending on the screen resolution so that the contents of the form will always fit, irrelevant of the screen resolution/size of the computer on which it is being run?
Thanks a lot!
Assuming you are using WinForms, your best bet in this case is to make use of the various container controls included in the framework, like the FLowLayoutPanel and TableLayoutPanel.
If you want to avoid these, use the standard Panel control and make use of Dock property to ensure it fills the required areas correctly. Then use the Dock property on all your controls to make the layout more responsive to different resolutions, and more importantly different DPI settings in Windows.
I know there will be folks who will vote this question down or ask for close. But if there is any kind of information or code I can provide you to know more about my program I will let you know. So please keep reading and see if you have had a similar problem.
I am running a Win7 64bit with .Net Framework ver 4.5.
I have created a Winform application. And to create my form elements I have taken advantage of a library called Metroframework that gives the program a metro look and feel. It contains some standard controls and as well as user controls that inherit from the original Form class. This is the opening view of my program.
However, for some strange reason, when I came to install my program on two other computers (one running Win7 and the other Win8), I noticed that some of my form elements have changed their location and some have just disappeared or just have been displaced. This has frightened me knowing the amount of time I have spent to put this elements in place.
Everything looks fine on my own computer both in dev environment and after building my application in release version. At first I thought this is a screen resolution problem on the other two devices, but that was not the case either. And even if it was, why should this happen?
Can anyone please help me solve this problem? I will share any part of my code you need. But I really have no idea where the source of this problem is!
The main influence on the layout variations on different machines is theForm.AutoScaleModeproperty.
In theory the default setting should work fine but I found that sometimes it is best to switch it off completely, that is going from Dpi or Font to None..
MSDN explains a little about the intended effect.
BTW: The is also a ContainerControl.AutoScaleMode property, so you could choose different modes for some parts of your forms as described here:
The AutoScaleMode property specifies the current automatic scaling
mode of this control. Scaling by Font is useful if you want to have a
control or form stretch or shrink according to the size of the fonts
in the operating system, and should be used when the absolute size of
the control or form does not matter. Scaling by Dpi is useful when you
want to size a control or form relative to the screen. For example,
you may want to use dots per inch (DPI) scaling on a control
displaying a chart or other graphic so that it always occupies a
certain percentage of the screen.
To remain true to the pixel-precise layout use:
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.None;
The last value in the AutoScaleMode enumeration is Inherited which most often would be chosen for nested containers.
Update: The choice of ContainerControlsis rather limited:
System.Windows.Forms.Form
System.Windows.Forms.PropertyGrid
System.Windows.Forms.SplitContainer
System.Windows.Forms.ToolStripContainer
System.Windows.Forms.ToolStripPanel
System.Windows.Forms.UpDownBase
System.Windows.Forms.UserControl
Maybe the most useful is the UserControl. Note that it doesn't expose the AutoScale property in its instances but only in the class definition. Also note that you can't add controls to an instance in the desiger, but you could assemble them in maybe a Panel and then set a UserControl (with AutoScale=Font) to be the Panel's Parent.. You'll need to allow for some extra space in any case, though..
I've rewritten a toolbar that sits at the top of the user's screen. It works, but for some reason, though the app consists of just a form with a Fill-Docked ToolStrip, I cannot get it to stay at the size I specify. It's supposed to be the size of the Windows titlebar, as designed in Visual Studio, but as soon as I run it, it's grown in height by five or six pixels. Everything is set rigidly, the Form and ToolStrip are set to AutoSize=FALSE and I've specified the size in pixels the form should be. I cannot work out what is resizing the form at runtime; the ToolStrip is Docked on Fill mode so it should not cause the form to grow. It all looks perfect in the GUI builder, and I copied most of the configuration from the old VB.Net toolbar it will replace. Can anyone help?
Just a wild guess, but have you tried changing the AutoScaleMode property of the Form to something other than Font?
Haven't found an answer but I'll make sure this is closed. I turned the form transparent and it accomplished what I needed. Still unsure why the form expanded when run.
I have created a panel in c# application that holds rows of 5 textboxes.
Textboxes are added to panel dynamically. It is 500 pixels in width and each textbox is 100 pixels wide.
First textbox is at x-position 0, second at 100, third at 200 and so on.
So the 5 textboxes should fill the panel horizontally. These are shown correctly at my computer but at another computer these textboxes appear as if their width is reduced and they do not extend to end of the panel. They leave blank space at the end of panel.
Can anyone tell me why is this difference in display of textboxes?
There could be a few different reasons for this. Depending on if you are using WinForms (which I am assuming) or WPF. There is a system DPI that can be changed in windows. Windows Vista and 7 take advantage of this more. The other issue could be with the windows themes (play with the handicap themes). How to check your system DPI
I think that the problem is in displaying textboxes in computers with diferent Windows themes.
With Classic windows controls it compute space in different way than when themes are turned on on computer.
Couple things to try, make sure the AutoSize property is set to false on the Panel and the Textboxes. Also, make sure the PreferredSize is also set.
I was having a similar problem, and found this link:
C# WinForms messed up control positions?
where changing my main form's AutoScaleMode attribute from Font to None or Inherit solved the problem (NB: changing to Dpi did not solve it).
