I have a text box where i am entering numbers of double datatype andon the Keytdown event of the textbox some checks take pace and in certain circumstances I want to be able to stop the user from entering other information until they enter the right information in the textbox (where it says right here) . now when I say exit sub the textbox somehow loses focus . but this is not how I want it to be I want the textbox to remain with the focus so the user can change the information . How can i go about this.
And the other thing is why is my txtDestPayRate1.Focus() just befor the exit sub not working? because I am giving focus to it so whats happening or rather why is it not happening Is there a way other than exit sub to tell it to stop executing on that line and do other stuff

I am entering a values into another textbox and I want it to surrender Focus to another textbox if the value I have entered is the same as the one in the database.However what is happening is that if the value is the same as in the database the cursor just disappears and it does not give focus to the control that I want it to give focus to. Any ideas on how I can correct this.

I am working on a carputer app, and it will be relatively basic with common tools. I am going to make an onscreen keyboard that fits the style of my app, but I want to make it a seperate application from the main app. All I want it to do is is have my keyboard become visible whenever I enter a text field of any application, whether it be programmed by me or a third-party app. Think about this in the way of a smart phone... Whenever you enter a textfield the system keyboard is displayed.
how can I put this idea in code to say: if TheLastFormVisitedIsFormCustomers then
CurrentForm.myTextBox.Focus End If
In simple english. How can I retrieve the name of the last form visited in code and give focus to a textbox control depending on the last form visisted.

I have a text box in my application. When I open it, I type "Hello" and then close. When I open it again, the text is obviously gone. Is there a way now to keep the text and any changes in there rather than making the program save a .txt upon closure, and then opening it every time the application loads? Would the same code go for a checked check box, or a certain radio button, data grid view, etc. ?
when clicking a button, the current date is inserted into a textbox and the focus is transfered to the textbox.

Using VB 2010 Express.I have a TextBox on a form. I want to be able to enter some text, then press either the {Tab} or the {Enter} to leave. Tabbing out seems to be the default behavior, so no problem there, but how do I get the TextBox to respond to the {Enter} key?

I am new to visual basic. I am putting a masked text box that is data binded. Example social security number 000-00-0000. When the cursor is on the masked field, a can no longer exit the field. I tried a couple of things on the forums but it has not worked yet. It could be a very simple but I am failing to see it.
how I can allow the program to exit while the textbox is empty but I can't figure out how it works really..it will not allow me to exit,enter, or tab out of the textbox while its empty.

I'm having a bit of a problem getting my application to close properly. Basically I have one main form from which all other forms open. If a user tries to close that main form, I want to bring up a MessageBox asking if they want to exit the application.However, when I try to do that it asks the question twice. It seems that the Application.Exit() is triggering the FormClosing event again for some reason, but I don't know of another way to exit the application. BTW, the main form isn't the startup form so I can't use the option to close when the startup form closes.
Now I have a sub to validate a bunch of textboxes and combo boxes.I previously used many IF statements to validate and pop up different messageboxes and Exit Sub in every IF statement.But I heard that too many Exits will decrease the efficiency and they were not recommended to use. Instead, nested IF is better because it will let the process naturally go to the end.Then I found out that if I use nested IF,it will be hard to read, since messageboxes are all separated from conditions.
Basically, 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.
I have a form with + 50 controls and with key numeric screen to write in only 5 textbox of this form.I am using this code to write in these textbox using key numeric screen:[code]I need to know which of these 5 textbox had the focus before touching the numerical button.I have seen this code from this post Find out the control with last focus to find last focus:[code]But how I do it in a form with + 50 controls (Controls of many types: buttons, checkbox, combos, textbox, etc.) ?

In my project exercising the PrintDocument Control, I want to set the font of one of 5 text boxes, Print location, etc depending upon which textbox has focus. I was hoping to loop through a text box array until the box with focus is found and use a vb6 trick like 'If tb(i).gotfocus then SetFont(i)' but the 'gotfocus' property seems to be missing in vb.net.Although I could use a button click or mousedown event

When the form loads, I query the dataset, and populate the dataGrid with initial values. My problem is that I cannot set the focus to the textbox. I have done the obvious (textfirstname.focus()), in the form loaded event.

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'm making a desktop application in vb.net. When I click the back button (placed by me) on any form it hides current form and shows previous form but when i go again to the form from which i had hit back button then the focus cue still remains on the back button but I want the focus to be on the first textbox on that form or any specific button on which I want.....How can i achieve this...

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.
I 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).
I do have a check in the TextBox.leave event that checks for empty values using
