Select All In Textbox During Runtime?
Oct 15, 2009
The textbox that I create in vb.net does not let me select all the text using the common keystroke control + a at runtime. The textbox is able to detect all other keystroke combinations at runtime, such as control + c, control + v for cut and paste, but it does nothing for when the keystroke control + a is pressed. Is this something that vb.net textboxes do not detect and therefore I would have to program manually by having the program detect keystrokes and then have the program select the text using the code TextBox1.SelectAll() ?

Is it possible to have a Textbox on a form that when the user inputs data, ( during Runtime )that data remains in the Textbox for good and the Textbox then becomes read only ? Is it also possible to make it so that the CD with the programme on, is in the PC when the programme is being used. Perhaps writing the Textbox data back onto the CD ?

I am writing an app that puts multiple controls on a form at run time and then I edit the controls in a property grid. All that is working fine. I'd like to 'mark' the contol when it is 'selected just like visual studio does with the dotted border (or soemthing similar, I don't care that it is just like vs). I'm already using MouseDown event to grab the control and send it to the PropertyGrid, but I have now wired it up to take multiple controls and need to 'identify' them on the screen.

I am trying to code in .Net to select an area and the area will be where ever in the form, that is not restricted to a control and asusually the area appears like a square by dragging using mouse at runtime on the form and if on clicking on a button for ex "Save" i.e., saving the selected area and when the next time the page loads that particular area should be clickable.Right now i have no idea where to start but if some idea is given it will be more helpful to me to develop some code for this functionality. Does any one give a small idea that how can I do this functionality, so that I can proceed developing code?

I want to be able to select any control on the vb form at runtime. These controls will be added to theform on a click of a button. So essentially I want to dynamically be able to add and then select these controls at runtime. I would also like to make these controls dragable on the form.

I have a form where I have to use control arrays to create a multiple input form i.e. rather than processing one transaction at a time up to 16 transactions must be processed. The following really havent given me much problems at this moment labels and textboxes. I use a for construct to create all the controls including a combobox. This is where my question comes in this form combobox has to be linked to a table in a database. But furthermore and this is where it gets complicated for me anyway each seperate combobox must move independly if i select row 5 in the table in combobox 4 combobox 5 which is havent touched should still be on row 1. How do I accomplish this. I'm using a webservice. I have tried passing a loaded dataset . The code that loaded the dataset is as follows
Dim DSInfo As New Project1.localhost4.AccInfo
DSInfo.Credentials = System.Net.CredentialCache.DefaultCredentials
InformationData.Merge(DSInfo.GetBusinessJournals)
[Code].....
this code doesnt however provide a link to the table equallly creating a dataset in the combobox method ,loading it and then setting it as datasource also provides no link. I know i'm missing something.

I'm developing an application to allow engineers to conduct simple single table/view queries against our databases by selecting Database, Table, Fields.
I get how to use the Dynamic LINQ Library Sample to provide for dynamically selecting the Select, Where and Order by Clauses at runtime but I'm at an impass on how to allot for table choice.
Is there a way to provide for dynamically selecting the "from" table at run time
EDIT
So Both of the answers seem to be saying the same general Idea. I'm going to try to convert the C# into VB and get it to work.
The first answer converts to
NotInheritable Class DataContextExtensions
Private Sub New()
End Sub

I have a form, with lables and textboxes added at runtime. The labels and textboxes are added properly on form load and display as expected. The form allows tabing into each of the textboxes, but the textbox does not allow user input.
Is this a problem with the way I show the form to the user? >> this particular form is called (frmname.show) from a different form -- If I test this form directly, without being called from a different form, it allows user input in the textboxes. Is it because of the properties I used to create the textbox? >> properties used were - .name, .size, .location, .tag

I am trying to make a program in Visual Basic 2008 Express edition which have a textbox where the user can write information to search for in a simple database stored in the program-code.
What I would like is that when the user types a word, a string variable connected to that textbox.text will be treated as a string. BUT if the user types a number in the textbox, the textbox.text will be treated as an integer (for example a "Double")

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.

msgbox(text)
Anytime I do this, I just get the textbox name eg, "Textbox10.Text" I am using Visual Studio 2010
