I need to set a variable upon the user scrolling to the end of the text on the textbox ("Scroll to end to accept terms") type thing but I can't seem to find how to get the value.
View 2 RepliesSo with the stock Textbox, I set the Scrollbars property to Vertical. This is great if the text in my box never changes; I can scroll up and down while the box sits still. If I'm running a background operation that logs output to the box though, the scrollbar resets itself to the top every time I append text to the box.
I know I can set the Textbox.Selection property (or use the Select method) to reposition the carat in the textbox, make note of that position in a variable, then append text, reset the carat, and use the ScrollToCarat method to reposition the scrollbar where it belongs. That's a really (ridiculously) long way around. Anybody know if there's another/better way of holding the scrollbar position, short of actually building a custom control (or using a Textbox and a separate Scrollbar)? It never hurts to try. In a worst case scenario, you'll learn from it.
I have a TextBox control with a lot of text which has a vertical scrollbar, and every time I hide/show the control the position of the scrollbar stays the same. I'm trying to figure out how to change the position of the scrollbar to the top of the textbox, as if it were at the beginning of the text.
View 1 RepliesI've been using 'GetScrollInfo' to find the position of the scrollbar on a ListView and I can detect when it hits the bottom of the list. Is there anyway I can raise an event when the scrollbar changes? At the moment I have it working by using a timer but I would rather if possible create an event to fire my routine.
View 1 RepliesI have one gridview which was in a panel and I set panel's Scrollbars property as vertical and height 200px. Gridview has number of rows (say 1000). If i scroll down and selected a 900th row,scroll bar will move to top.I want to focus on that row after selection(ie.scroll bar will be on the same position when we selected).

View 2 RepliesA couple of questions about the FolderBrowserDialog in VB .NET Express 2005...
1. How can I make it so this control allows selection of multiple folders at a time?
2. It remembers the folder I selected last time (in the same session), and highlights that folder, which is good, but that selected folder appears near the bottom of the window. Is there a way to make it so the previously selected folder appears in the middle of the window (i.e. the scroll bar is further down the window)? See screen shot attached for how it currently looks when the window opens.
Very simply, I'm positioning a small ListBox over a DataGridView column when the user right-clicks and selects "Show Distinct Values". This works fine until the vertical scrollbar of the DataGridView is clicked. Once that's done the listbox pops up all the way over to the left edge of the DataGridView. As confirmation of the problem I created a small app to test with.

I have a listbox on my form which gets items added as the program progresses, when there are more items than the box can display, the vertical scrollbar appears, fine... so far so good.I would like the scrollbar default position to be at the bottom of it's column so that the last entered item is displayed but can't find the relevant command, I assume there is such a command.
View 2 RepliesI am currently working on a VB.Net program where there are two parallel multiline text boxes like this.
----- -----
| | | |
| | | |

I would like that when one text box is scrolled, the other is scrolled as well. I was wondering if there was a Scroll event that could trigger the change the position of the scroll bar of the two text boxes.
Is there any way of detecting the position where the Mouse Button is released during a Drag & Drop operation. I need to know whether the intended Drop position was not reached when the mouse button is released.

View 6 RepliesI have two panels, and I want them to both scroll horizontally with one scroll bar, but I only want one of them to scroll vertically. So if I have a large panel on autoscroll, it works fine for that panel, but I have another smaller panel above that, could I make the smaller panel scroll horizontally with the larger panel's horizontal scrollbar?

I have tried searches and try and fail but I cant figure it out
I typically prompt the user to save changes in the FormClosing event in MDI children. The application updater uses a Process.CloseMainWindow call to close the application if it's running before the patch update is applied.
I need to detect when the updater is closing the application and NOT prompt the user to save changes but save them automatically. I've tried using the System.Windows.Forms.CloseReason but this method isn't working for me. I capture the CloseReason in the MDI Parent FormClosing event but it's called AFTER the MDI children are told to close. I tried capturing the CloseReason (e.CloseReason) in the MDI child's FormClosing event but it registers as MDI Parent closing and a normal application exit is also going to raise this same e.CloseReason so I can't auto-save here either.
So my question is: How can I detect this Process.CloseMainWindow being used to close my application so that I can bypass all save prompts and save automatically? What is the first event called in this method of closing so that I can signal all MDI children that are open in their FormClosing event to just save?
I'm trying to allow scrolling in a Multiline-TextBox even if the TextBox is set to
textbox.Enabled = False
This is not possible, as the Scrollbar is disabled with the Enabled-Command, too.The default solution here is to set
textbox.ReadOnly = True
textbox.Enabled = True
but this doesn't really do the trick for me. With ReadOnly I can still select the text of a TextBox as well as place the cursor inside of it. But as I have normal (non Multiline-TextBoxes) and other controls on the same form I don't want that to happen. I want to have exactly the same behavior as all the other disabled TextBoxes.
For everything else, like mimic the color of a disabled textbox and so on, there is a legitimate workaround with the ReadOnly-Property, but I coudn't find any for selecting text and placing the cursor.
UPDATE:I tried to use WIN32 API but it didn't work as expected:
Imports System.Windows.Forms
Imports System.Runtime.InteropServices
Public Class TestTextBox

I want this part of my project to detect spaces because it can happen if the user puts in a certain value for on and that value begins with another it will not process. (ex. a.text = 123, b.text = 1234, then i get the outcome or "aa" and it should be "ab"
I have a series of textboxes that I need the user to be able to navigate. When the last textbox in the series is filled I want the cursor to go to the first box in the series and have the next row in the datagridview selected. The problem is, for some reason, the tab button being pressed (keyup, keydown, and keypress) is not being detected by the conventional handling of those events. Instead, the tab on that box goes to the next item in the tab index.How would I capture that key or key press event and execute my code?
View 3 RepliesBasically, I have a program that uses up one Monitor (With maximize/minimize/etc options), and I'm going to develop another window that by default, you'll have to swap to. But, if there are two or more monitors detected, throw the 2nd form on the 2nd monitor.
I have found a way to detect multiple monitors (Using the SystemInformation Class to return the monitor count), but it's placing the form on the other monitor that's the problem.
I would like MyProcess() to fire when I click on any of several checkboxes. I could do it like this.

View 6 RepliesI'm new to VB 2010 but have be using VB6 for many years.I'm currently stuck trying to store the state of open MDI childs at the moment the MDI parent is closed. Clicking the parent upper right close button appears to close all open MDI childs before running the parent 'Closing' or 'Disposed' events.I am therefore unable to detect which MDI childs are open and cannot restore them next time the application is run.Is there any other event for the MDI parent I can detect the start of the closing process before the children are closed?
