I have a some winform applications which lose some controls when opened on a large monitor with windows 7. I created the applications in XP initially but I when they are opened in windows 7 some of the controls vanish from the screen. I set the attribute of FormBorderStyle to Sizable but I was wondering if anyone had any different or long term solutions?
As stated here, Docking may be that, what you need. I actually hadn't any problems of this matter but as an alternative, scaling the controls to a relative size may also help. See the first link for more information.
Use any kind of Container controls like Panels/GroupBox controls and properly dock your controls inside it and also containers aswell. If you have specific requirements using Anchor Property on the control also will also help.

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 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 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..
My C# Window Form size is 1364,835.It is shown perfectly in my PC.But while running with my Laptop(small screen size),only part of my form has shown in the visible area.How can able to fit this size issue among all systems.
do i need to add verticall scroll bar to my form?
Please Guide me to get out of this issue...

If you have not done much work on the windows application in that case you can think of using WPF, as WPF is more capable to handle this.
Still if you want to use Window application then make sure that your controls layout properly when their size changes. Use the Anchor and Dock properties. You can also use TableLayoutPanel in GrowAndShrink mode, but remember you might face some flickering issues if you use TableLayoutPanel in excess.
You can check MSDN for Auto Scaling here
you can set one property of form
WindowState = Maximized
just try this...
useanchoring, docking and etc.
look at microsoft outlook when you resize the window it changes looking another softwares can help you
suppose i have label and button on textbox and i want that if i resize my win form then my label and button size and position will change. i got the solution in wpf but i am working with win form apps. here i am giving the url from where you can see what kind of output i am looking form. the url is http://i.stack.imgur.com/QeoVK.png. please see the image and tell me how can i implement the same output in win form apps. please help me with code snippet in c#.thanks.
You should make yourself familiar with the Anchor and Dock properties of the controls. They are great tools for this kind of work.
Note though that they will alter the size of the controls only, they will not affect font size.
consider that window forms and WPF are very different, especially about the UI management and controls nesting / UI composition.
I have seen some articles describing what you are trying to do now in windows forms, long ego, it's something called control scaling if I recall well.
Use Anchor and Dock properties for simple stuff and SizeChanged event for more complicated stuff. UI positioning API is much more limited than WPF and you will probably have to do stuff like scaling manually.
