Ok basically what I am doing is using panels to create virtual "pages" within my application, and using buttons to switch from page to page. However whenever I click the button to move from page1 to page2, page 1 disappears and page2 does not become visible.

page2.Visible = True
page1.Visible = False

I populate a hash table with the name of a control as the key and the control itself as the value using the following code that loops through my code on start-up:

This method works effectively, but the only problem is I seem to get a preformance hit as it takes a second to set the current control to false and the new one's visibility to true. What way should I modify my code so that it works more efficiently?
when clicking a button, the current date is inserted into a textbox and the focus is transfered to the textbox.

I am in need to delay the execution of a line of code, say, by 5 seconds. But by doing System.Threading.Thread.Sleep(5000)
the whole UI hangs and I don't want that to happen. Because I want to be able to display something in a Window that a user will be able to see. Does anyone know of an alternative of achieving this?
In VB.NET projects, errors are highlighted immediately after cursor leaves the line. In C#, I have to wait several seconds for IntelliSense to highlight it. Also, the C# version doesn't show all project errors in "Errors List", unless you start to build it. Actually, it seems to work differently in every way. Is it possible to adjust that behavior?

I have a datagridview on my form. The datagridview has a bindingsource on a table in a dataset. I filter the datagridview on a boolean field:
tblTransactionsBindingSource.Filter = "Complete = False"
If you click on Complete on the datagridview on one of the rows being displayed the row disappears. Well, almost. It disappears after you click on another row. What property do I need to set to cause it to disappear immediately? I tried EditOnEnter and that didn't work.
I have a picture on a form, and when the user clicks the picture, its image source changes into an animation and loads a new form.The problem is, the new form loads and only the first few frames of the animation is shown.
View 4 RepliesI'm having a hard time figuring out why this is happening. When I check an item in the listbox it calls the sub ItemCheck for the listbox accordingly:
Code:
Private Sub chklbToDo_ItemCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.ItemCheckEventArgs) Handles chklbToDo.ItemCheck
Dim iLoop As Integer
Dim iCheck As Boolean
[code]....
I've had to work with the delay of the check by reversing the boolean value caused by the check. But when I worked it into the program to delete the item that is checked, it deletes the selected/(un)checked item and THEN checks the item with the index. So in other words, if a user selects and checks an item in the listbox, and chooses to delete the item, it deletes the item and then checks the item that replaces it in the index (the following item).I don't understand why the checked value doesn't appear until after the sub ends.
I want to make a project that when form loads the form follow the mouse [delayed and smoothly]
View 16 RepliesBasically, I have a form with about 15 text boxes. Most are in different tab pages. By default, text boxes allow anybody to copy and paste by using keyboard shortcuts.I added a tool strip up top and make the "Cut", "Copy", and "Paste" buttons. What I want to do is make them work for whichever text box was last focused. So if I click the Cut button on the tool strip, it will cut the text of the
last text box that was focused.
Example:I open the program and type in TextBox1. Then I type in TextBox2. I want to copy the contents of the last text box by using the Copy key at the top, so I click that and it copies TextBox2 as it was the last focused textbox.
Like I said, I'm not fully sure how possible this is as I do have many. The whole reason I have the tool strip is for users that prefer using a mouse for everything rather than keyboard shortcuts.

I am writing a control in WPF that draws a shape on a form and then draws dimensions of this shape. These dimensions are editable so they are shown in a text box. When the user changes a dimension in a text box the shape is updated. I am updating the shape when the textbox showing the dimension loses focus i.e. as soon as the text box loses the focus the shape and all the dimensions are redrawn.
A text box loses focus in one of two ways - either when user presses tab key or when user clicks in another control outside the text box. My problem is that when user presses tab key or clicks somewhere else outside the text box the whole control is redrawn and the focus is not set to the next control where it should be. This is really annoying because tabs stop working altogether and to set a focus using mouse the user has to click twice.
An image of my control is shown below

When a Windows Forms TextBox control first receives the focus the cursor has to be there at first position in the Textbox.
We have tried to resolve the above issue by adding below code in form load event.
TextBox1.SelectionStart = 0
TextBox1.SelectionLength = 0
Now, when a Windows Forms TextBox control first receives the focus, the default insertion (cursor) within the text box is to the left of any existing text. The user can move the insertion point with the keyboard or the mouse. If the text box loses and then regains the focus, the insertion point will be wherever the user last placed it.
But the problem is when some operation is performed in TextBox_Leave event, it will loose the focus. Again when it receives the focus, the whole text is getting selected instead of showing cursor where the user left.

I have simple application that basically allows you to open up and view PDF files.I use an OpenFileDialog control to select the PDF file and a WebBrowser control to view the file (via the Acrobat ActiveX). Everything works great. However, I would like to also record info, from each PDF file that gets viewed, into a TextBox control (someone would read a line or two from the PDF file and type a summary into a TextBox control). Once the PDF file gets loaded, it takes the focus. But instead, I would like the focus to move the TextBox control. Changing the focus upon the Web Browser1_ DocumentCompleted event does not work (I don't believe the WebBrowser control is aware of the PDF itself, just the ActiveX control) In fact, the only way to move focus to the TextBox, after the PDF file is loaded, is to click the TextBox with the mouse. I can't �TAB into that field.
View 9 RepliesI have a Windows Form Application that has a few TextBoxes, Buttons, and a couple of ListViews. One of the TextBoxes takes an entry (usually by a barcode scanner or the user can type text and hit the TAB character) and then that searches through some data structures and if found it modifies the color on a row in one of the ListViews and adds a row to the other ListView. What I want to be able to do is to put the focus back on the Textbox that takes the input from the barcode reader.The problem I'm having is that the TextBox doesn't always get focus back after a scan. Sometimes after a scan it looks like the focus is on one of the splitContainers. I can manually take the mouse and put the focus back on the TextBox, but that would be kind of inconvienient for the user. What I would like would be for the user to be able to scan (which enters text into the textbox and then TABS out). The TextBox's Leave Event fires and runs the code that manipulates the ListView's and then at the end the leave event code clears the textbox with TextBox1.Text = "" and then calls TextBox1.Focus()
I've tried using TextBox1.Select() and/or TextBox1.Focus() and neither one works. I even put in a Apllication.doEvents() so that any pending action that might cause focus to change will happen before I call the Focus() or Select() code.My guess is that maybe it has to do with some race condition on actions that pull focus away, but how can I keep focus on the text field and still allow the user to use the mouse to press the EXIT or SAVE buttons or even click on an item in one of the ListViews (which doesn't do anything right now).
