Find Out If The Vertical Scroll Bar Of A Text Box Is At The Beginning Of The Text Box Or The End?
Mar 22, 2012
I have a wrapper class created around TextBox, and I want to find out if there is any way to test if the vertical scroll bar is at the beginning (the very top) of the text box and at the very end of the text box.Alternatively, I will be happy if only I can find out a way to check if a scroll bar is enabled or not in a textbox (note: it's not a RichTextbox).
By enabled, I mean that scroll bar is actually enabled i.e. you can use the scroll bar to scroll the control, not just visible (I know we can check visibility by GetWindowLong)
My rich text box overflows with output during execution, thus activating a vertical scroll bar. When the program ends the created text box information disappears.I have tried a message box prior to exiting the program to stop execution but then nothing responds until the message box is A instruction doesn�t accomplish my goal either. I see nothing in the text box properties window which looks like it would do the trick and no luck with Googling for info so far.
I have a listbox where each line contains a short 3-4 character model number followed by a tab and then the product name the model number corresponds to. I also have a textbox which I am using to search the listbox.
The code I am using so far works somewhat, just not exactly how I would like. If I enter search text it will highlight the results in the listbox but only for the first characters, is there anyway to search the text of an entire line (index) of a listbox?
Right now I am using the following:
Private Sub txtSearch_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtSearch.TextChanged ListBox.SelectedIndex = ListBox.FindString(txtSearch.Text) End Sub
I am loading several command buttons into it (one in each grid box). I have the panel set to autoscroll. When TableLayoutPanel is set to AddColumns, all works well. However, I dont want horizontal scroll, I want vertical. When I set TableLayoutPanel to AddRows, a vertical scrollbar will not appear.
How would I leave the vertical scroll position as it is and set the horizontal scroll position all the way left if it isn't already in that position? I've been using Me.AutoScrollPosition and have come up with code that is satisfactory but I haven't been able to always leave the vertical scroll position exactly as it is and just move the horizontal scroll position to the left limit.
I have a textbox that shows events on a program, which I add. I use the 'scroll bar' option on the textbox to show the vertical scroll bar, but how do I make it stay at the bottom most possible? I am using this code while I am trying to learn how to do what I want the scroll bar to:[code]But how do I get it so the scroll bar will stay at the bottom-most it can? I'd like the newest, most recent events to appear at the bottom of the textbox, and to have the user not have to scroll down every time something new is added.
I have an SQL database, and 50 text files, and Visual Basic 2010 Premimum,I need to find a specific line of text in the text files and then take the next 37 lines of text and save them in my database. I need advice as to point me in the right direction
I have a small project which I want to add a different text at the beginning and the ending of each line in a multiline text box.I've tried this, But It only let me to add it at the beginning ( because I don't know the length of each line And also I have to write a code for each line which is very hard because the text box may contains 200 lines Dim lines() As String = TextBox1.Lines lines(0) = lines(0).Insert(0, "Hello World")TextBox1.Lines = lines I want for all lines without having to repeat it again for each line
selects a part of the text and sets the cursor (blinking beam) at the and of the selection, in this case the first caracters of the selected text is out of the user sight because the textbox is too small to display the entire selection.
Is it possible to force the cursor to be at the beginning of the selection so the first part of the text is visible? (as if I had selected my text with the mouse dragging from the end back towards the beginning)
In VB 2008, if one drops a vertical scroll bar on a form, by default the maximum value is 100, the minimum value is 0. If you place code in the scroll event to put the scrollbar value in a label, then run the program, the values in the label will range from a low of 0 (expected) to a high of 91 (unexpected).Why is the maximum value displayed in the label at 91 and not 100?
'm currently having trouble with a textbox. If the text in the textbox is longer than the textbox itself, it will display the end of text to the user. I need it to display the beginning of the text to the user. Is there a possible way to force that to
I have a masked text box for postal codes. When the user clicks the text box it sets the cursor to where ever they clicked in the text box. Is there anyway that if the value is empty it sets the focus to the beginning.
Private Sub Cust_postalTextBox_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Cust_postalTextBox.Click Try
[Code].....
Is the code I have that works but What would the IF statement be to check if it is empty? String.empty and "" don't work because I think it sees the mask as characters.
My problem is that when I click continiously the bottom button of a vertical scroll bar (datagridview) the datagridview maximises and expants to all my screen.
How can I programatically control the position of the vertical scroll of a DataGridView? I need to keep visible the last row added to a table and showing as the last row at the bottom in the DataGridView control so the user doesn't have to be scrolling down every time to see a new row that has been added.
I can see the use of the Offset for the Horizontal Scroll Bar but for the Vertical Scroll bar of the DataGridView it can only be "Get" but not "Set".
I've got a vertical scroll bar and I noticed that it's .Value is at a minimum when the bar is at the TOP (Why is that anyway?). Well, for visual feedback purposes I need it reversed where .Value is the max when the bar is at the top. Now I realize I can just manipulate the .Value in the software to get what I want but I was just wondering if there was a property I could set to just reverse it. I looked at the Object browser and couldn't find one. Sorry about these simple questions it's just that there are SO many properties and methods to learn...and I'm amazed anyone can remember all of these....
I have a windows form which contains a group of panels in a flowlayout control. Each panel has a button acrossthe top which is always visible and clicking on it expands the panel to view the other controls on it. clicking on it again shrinks the panel back to the size of the button. A simple form of menu. The flowlayout control has autoscroll enabled and as enough panels are resized (opened) they obviously are too big for the form and a scroll bar pops up.To get the most recently opened panel in the viewable area I use
FlowLayout.ScrollControlIntoView(pnECBF)
where pnECBF is the panel just resized. This works but places the panel at the bottom of the form i.e just in the visible area. I want the user to be able to see the panel AND the next menu button which is on the subsequent panel. So basically what I want is the panel into the visible area +25 pixels for the next panels menu button.
I have a datagridview for showing the reports. Here the datagridview vertcial scroll bar wont workbut it show the both horizonadal, vertical bar.but horizadal bar only worked anot vertical bar.I have explained my process. I have taken a report from Exchange server and stored the Sql database. After finishing the data collection then I have again select some of the fileds only from Database via datatable. I have copied my datagridview using datagridview datasource.
I've been searching for a while on an answer to this problem. I have a datagridview in my vb.net app and the right most column holds multiline cells. The vertical scroll bar doesn't redraw correctly:
I have to fix header of table when i scroll down i want to see column header till the end of records. i made this but i am facing a problem. i fetch data from database that's a dynamic data so when i display that in table the layout gets odd. because if there is a column with more than 1000 words that will change its width while i mention table cell width with percentage. how i can solve this problem that header remain on the top and the layout will not be disturbed what ever data is. i do not want to use jQuery
i have a datagridview with the scroll bar property's set to "both", but when the data is too long horizontally it wont show the horizontal scroll bars only the vertical. And instead it puts "..." The DGV isn't docked, or bound to any data source, im adding data programmatic
I have the following code to resize the datagridview but the vertical and horizontal scroll bar are not shown when there are colunns and rows exceed the width and height of datagridview objects.Bascially the following code is similar to dock to the botton, the only difference is docking to the botton change the Y position of datagridview and fill the botton section whereas my code fix the Y position of datagirdview and fill the bottom.[code]I have tried with the dg.ScrollBars = ScrollBars.Both but it it is not working as well..May i know how to get both scroll bars working.
I have a datagridview in my for that contain some infos like name of a file, date and hour but the vertical scrollbar doesn't work, the scroll doesn't move. Here's my code
If Me.ofd_Fichier.ShowDialog() = DialogResult.OK Then Dim str_Fichier As String For Each str_Fichier In ofd_Fichier.FileNames
I would like to have the tabs on my TabControl displayed on the left, or sometimes right. Unlike the System.Windows.Forms.TabControl, however, I would like the text to remain horizontal instead of being rotated by 90 or 270 degrees to the horizontal. Here are a couple of pictures illustrating the concept. Though I could write code to do this myself in about an hour or two, I just thought I'd ask first if there is any existing Winforms control that implements such feature.
I'm using the following calls in a vertical label control: (borrowed from another project)[code]But if any of the text characters are a V or W there are funny jagged artifacts in those letter's angled lines. Does anyone know how to fix this? I tried looking up anti-aliasing etc.. but aside from changing the smoothing mode to antialias I couldn't find anything (changing this doesn't help a bit)
