I am developing a Windows Form Application. I want to Align the Text to Right of Title Bar of Form. I set RightToLeft property to Yes, it worked in design time but didn't work in run time.
How can I do it? I don't want to set RightToleftLayout to True.
I think you don't have a function or something of visual studio who can lead you to do this.
The title bar of winforms is a native application of Windows, so it's not a good idea to move things on it.
But if you really want to do that, or you really need to, you can do something like this:
this.Text = " " + this.Text;
And modify any way you want.

My issue is in the .NET framework using C# to create a simple form application that contains a rich text box (RTB) control.
Briefly the issue I am experiencing is that when trying to clear the contents (.Text) of the RTB, the scroll bar doesn't go away. I would like to know if there is anything inherently wrong with the way I am using the RTB. I apologize, but the site will not allow me to post images yet. So if there is a misunderstanding regarding what "doesn't go away" means, please ask!
So first, I write data to the box using the following code snippet:
// append the new message
this.rtb_receive_0.Text += message;
this.rtb_receive_0.SelectionStart = this.rtb_receive_0.Text.Length;
this.rtb_receive_0.ScrollToCaret();
Later on, I clear the RTB contents (RTB.Text) with the following code:
this.rtb_receive_0.Text = String.Empty;
this.rtb_receive_0.Refresh();
In the above code I have attempted to fix my problem with the, "Refresh," method. However it does not seem to be doing the job.
When I clear the RTB contents, the scroll bar does not go away... I noticed that if I grab another window and drag it over the top of the application, that the frozen scroll bar disappears. Also, I can minimize the application, then maximize it again and the bar will disappear. There has to be a way to prevent this frozen scroll bar from happening in the first place though.
Per the answer, here was the fix to stop the bar from freezing up:
this.rtb_receive_0.Text = String.Empty;
this.rtb_receive_0.Clear();
this.rtb_receive_0.ScrollBars = RichTextBoxScrollBars.None;
this.rtb_receive_0.ScrollBars = RichTextBoxScrollBars.Vertical;
this.rtb_receive_0.Refresh();
Have you tried simply just programatically setting the Scrollbars property on the RTB?
myRichTextBox.ScrollBars = RichTextBoxScrollBars.None;
Edit: I think I misinterpreted what you needed. Searching around, I found this similar post on another forum: http://www.vbforums.com/showthread.php?793671-RESOLVED-RichTextBox-Visual-Bug
This user is setting the value of an RTB based on a selection in a list view. When a new value is set and does not require a scrollbar it doesn't re-draw and still shows the bar.
It seems like adding myRichTextBox.Clear(); myRichTextBox.Refresh(); should help. In this case that user is also programatically setting the ScrollBars property as well.
Also, are you able to determine how many lines of text can fit in the RichTextBox before a scrollbar is needed? I suppose that might vary based on system settings on the machine, but you might just be able to programatically check myrtb.Scrollbars = (myrtb.Lines.Length > X) ? Vertical : None; (excuse the psuedo code syntax)
What helped for me was just calling the refresh() method twice. Very ugly, but it does the job.
Hmm, after more thorough testing this ugly fix proved to be not so much of a fix afterall. It helps, but still some glitches.
refresh();
update();
seems like a better solution.
I was having this same problem. I solved it by calling the Invalidate() method which forces the control to repaint.
Me.RichTextBox.Clear()
'Call Invalidate in order to force the RichTextBox to repaint. I do this so that any
'Visible Scroll bars are removed after clearing the Text
Me.RichTextBox.Invalidate()
I tried with Refresh(); Update(); Invalidate();,but it didn't worked for me.
I solved this problem using following three lines :-
RitchTextBox.Clear(); //Clearing text in RichTextBox
RitchTextBox.ScrollBars = RichTextBoxScrollBars.None; //Remove scroll
RitchTextBox.ScrollBars = RichTextBoxScrollBars.Vertical; //Again add scroll
Try those above three lines. It will work 100%.
I am new to WinForms and am currently developing a simple application. I am not too sure if it is possible, but I would like to display the Form's text value (or some text value) in the taskbar when the application is minimized, rather than the icon?
You can set the text of your application by:
this.Text = "Text that you want to display";
paste the above line of code in your Form's constructor just below the InitializeComponent() method.
The answer is Rohit Vyas's. But due to your comment, you're looking for:
Right-click on taskbar -> Properties -> Taskbar buttons: Never
Combine.
Title usually appears in the taskbar of Win xp and many windows
it can be set like this in win forms
This.Text ="Some Text";
But in Win 7 it will always give you the icon unless you change the properties of windows.
This is not possible without going into COM/Interop stuff and even then I would not advise it. Why not use a text icon instead, or you could look at the NotfyIcon Class.
I am a bit confused regarding C# WPF. How can I set a WPF window's properties from C# code? For example, trying ShowInTaskbar = false; doesn't hide the window's taskbar button, I actually have to do it in XAML for it to work. And that wouldn't be a problem, but I wonder, how do I control the GUI from C# code when using WPF.
This may sound like a retarded question, but I am trying to transition from WinForms to WPF.
you simply need the instance/reference of Window then you can do whatever you want with it in code.
try windowInstance.ShowInTaskBar = false in code it should work
Suppose I am trying to automate notepad, and depending on what is open, the tile of the window is either "Notepad", "Notepad - letter_to_boyfriend.txt", "Notepad - Readme.txt", etc.
When I recorded the coded ui test, it assumed the title "Notepad". Now I want to customize the test somehow, so that any title that looks like "Notepad*" would be good enough.
How can I do so? Sorry, I do not have recorded code to share at the moment, but I might later. Hopefully it is not that hard to reproduce.
It has got to be the search property.
Thanks in advance.
Doubleclick on the [mapname].uitest, in the UI Control Map select your window, press F4 to see properties, and finally in Search Properties change the Operator from EqualsTo to Contains and the Value to "Notepad".
Playback.PlaybackSettings.SmartMatchOptions = SmartMatchOptions.TopLevelWindow;

I recently started getting acquainted with Visual Studio 2010 and C# for an internship. C# doesn't include a built-in InputBox function, so I made my own form, with a text box, two buttons and a simple label.
I have a function set up to allow the programmer to call the form in regular format (where the user enters input via the textbox) or yes/no format (where the form just displays a question and the yes and no buttons).
When I switch over to yes/no format, I want to center the label programmatically. I've been using the code:
labelNote.Left = inputBox.Left + (inputBox.Width / 2) - (labelNote.Width / 2);
This should put the center of the note in the center of the form. However, if the contents of the label change (making the new label longer or shorter) the properties don't update to reflect the new size. It won't center unless it includes the original text. Is there some way to force an update? I foresee this becoming a problem with positioning objects for scalability in the future.
Thank you for your time
I'm assuming you have the sizing within an actionlistener. Specifically the forms' resize action listener. Then whenever the form is resized it is called and all of you code is recalled. Then to force an update from somewhere else you just have to call the actionlistener.
Actionlistener:
Private Sub formName_Resize(ByVal sender As Object, ByVal e As EventArgs) Handles MyBase.Resize
Calls actionlistener:
formName_Resize(sender, e)
Well, you could attach an event to Label.TextChanged. Frankly it would be better to change the TextAlign or something like that though: try to perform the layout in a declarative fashion instead of doing it explicitly through code. That tends to make things work rather better.
I've found the [TableLayoutPanel]1 control to be reasonably easy to work with - most of the time (and occasionally a complete pain).
It turns out that I made a stupid mistake (a common theme for me in debugging. The really small stuff goes unnoticed for the longest amount of time).
The label resizing was not the issue. The issue was the order in which I changed the contents of the label and then called the function to calculate its new location. I was calling the location calculation first, so it found where to center the label based on the old contents. I didn't notice for so long, because the text was changing properly. I took it for granted that the functions were being called in the correct order.
So, when it doubt, check the order in which you're writing your code. Thanks for you help anyway, everyone. I ended up finding out some neat things that could be applicable to other scenarios (such as the MeasureString function in the Graphics class).
