I have a textbox that I have set to be a readonly textbox but I also want it in such a way that it cannot receive focus I tried to disable the textbox but the grayish color is not very apealing to me.
View 2 RepliesI have a DataGridView with several columns. One column is a TextBox column named "Status". This column can only show one of three values: 'Final', 'Ready', or 'No Reportable'. I want to have some code that would turn the TextBox cell into a ComboBox cell when the user left-clicks on the cell to allow the user to choose one of these three options. When the user clicks elsewhere or the cell loses focus I want the cell to change back to a TextBox cell.
Here is what I have so far, but the code throws an exception indicated below Plus, I don't think the code would remove the combobox when the cell loses focus.
Exception: "Provided cell does not belong to this DataGridView control."

I really want to make use of the toolstrip and databinding but these two technologies keep conflicting with each other. I think the root cause is something to with the fact that the toolstrip buttons don't recieve focus in the normal way.
I invite you to try the following:-
1. Create a form and put some text boxes a tool strip with a save button on it.
2. Write a query or sproc to get a datatable back and bind your text boxes to the field in the datatable.
3. In the code behind your Save ToolStripButton put some code that makes an arbitrary change to a field on the dataset (it doesn't matter whther this field is bound to a text box or not). eg:-
m_DataTable.Rows(0).Item("CommissionRatePerc") = "0.0000"
4. Put a breakpoint in the save and run the form.
5. Make some changes in the text boxes. Do not leave the last text box but rather click save while a text box whose contents you have edited still has focus.
6. When your code hits the breakpoint, query the value of the data table field that is bound to the text box you were editing when you clicked save - it will still contain the unedited value. Unless you do something about it that unedited value is going to get saved back to your DB.
We did get around this problem by explicetely setting the focus to another control on the form before saving. That worked most of the time because it prompts the text box to flush it's value back to the datatable (nb EndEdit does not work, although you'd have expected it to). However, and this is the reason I suggested you add a line of code that changed a value in the underlying datatable in step 3, if you change a value in code in this way before the value from the text box get's flushed back then it doesn't seem to matter what you do, the user's current edit is simply lost. They will still show in the text box, though, leading your user to believe that the change has been committed when it hasn't. Our final solution is that we never ever change a value in the adtaset in the code behind our toolstrip buttons. That's working but it's a pretty big restriction.
I want to disable column in datagridview so the column will not receive focus,
when user press tab to move from cell to cell this column will be skipped and the focus move to the next cell or column.
when clicking a button, the current date is inserted into a textbox and the focus is transfered to the textbox.
the problem is that Textbox15.focus() select the text inside the textbox. i wish to give that control the focus but place the cursor at the end of the text, with no selection.

I am trying to make an app which can send/receive files/pictures. I am trying to make a app which will get a picture of the users screen and send it to me, and display it in a picturebox at a set interval. With this, I will be able to sort of see what someone is looking at without having to have him send screenshots constantly.
Remote assistance does not seem to work for these apps, shows black, but I can make the program already get an accurate screenshot and display it of this program, I just need to know how to make it send it to me and display it to picturebox.
The thing I have been using is the MultiUser TCP chat application off MSDN's website, I don't know if this will work, but I need to make it send somehow and display it.
My problem is i want to input a fraction a textbox, and receive the value or allow the application to read "/",.
View 1 RepliesHow do i make a messager in vb that should be able to send and receive messages from the server?
View 2 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).

I actually want to ask two things, first, how do I set Textbox1 to get focus so that the user will not have to click the textbox if he wants to write something, the .focus() method does not work also, how do I highlight texts inside a textbox programmatically.

View 4 Repliesi have a window form which has text boxs, buttons and radio buttons.when the form is loaded i want to put the cursor focus to TextboxA. But what i got is it didn't go to textboxA although I call TextboxA.Focus() at Form_Load event.In my Form_Load event() i have:
1) assign a value to a global variable.
2) hide a panel
3) set this TextBoxA.focus.

VB.NET Windows Forms Project, VS2010.I have a tabcontrol with several tabpages and on each tabpage there is a textbox.

However, the same code is not working in my actual project. I am having trouble debugging, because if I step through, the breakpoints and IDE mean the focus events don't fire in the same order.
