so yesterday this code was working for my userforms and today its not. Its a simple clear command for textboxes and comboboxes. what is from here?
Dim ctl As Control
ForEach ctl In Controls
IfTypeOf ctl Is TextBox Then ctl.Text = ""
IfTypeOf ctl Is ComboBox Then ctl.Text = ""
Next ctl
I would like to create a button that clears textboxes and comboboxes when it is clicked. For example when 'btnClear' is clicked then txtDate gets cleared (i.e. txtDate is 22/05/2000 then when btnClear is clicked it has nothing in it)
I have already tried
txtDate = ""
and
txtDate = Nothing
but an error comes up.
I have a windows form on which there is a textbox and a command button. When user inputs an integer in the textbox and clicks on the button, the userform grows and adds that many number of comboboxes and textboxes in a panel.
how to add variable number of comboboxes and textboxes at run time.
The maximum value of that integer would be 10.
I have three textboxes and a button. The button's role is to clear all the textboxes. This one textbox that I don't want to clear keeps clearing. What do I have to do for this one textbox to not clear up when the clear button is pressed ?
View 2 RepliesI want to clear all of the text boxes in a groupbox without hard coding them all. I tried the following snippet, but it also clears all of the form labels which I would like to keep.

I have developed a simple form with some checkboxes, textboxes, radiobuttons, and textboxes inside a groupbox. Initially I had all of this inside 3 tabs. I created a button to clear all selections so user can restart the process of selection if so choses. It does not work (see below). I thought it is the tabs - so I went on and removed them (by coping the groupbox - deleting the tabs and then pasting the groubox into the main form). The code still does not work. Is there a setting that I must change or something else because a created a simple form with a couple of groupboxes that had all the above mentioned and it works just fine - all of them clear. Just in my form it does not work
View 6 RepliesWhen clearing input from users. What is the difference between clearing it in these two forms
txtExample.Clear()
versus
txtExample.Text = String.Empty
The only difference that I could find was that the labels aren't cleared with .Clear() (or at least from what I inferred from my book that's not possible). Is there a noticeable speed difference or should I just clear both labels and txt boxes with String.Empty
I have several textboxes in a form, and have a button which inserts all the values in a Database and I have to clear the content of all the textboxes and focus to the first one right after pressing the button.Now I can easily do that using the Clear method of each of the textboxes but it takes 10-12 lines of code just for that. Can I do that in one go?
View 2 RepliesI'm using VB 2005 and have an Edit - Entry form with Textboxes and several Comboboxes. I populate the Comboboxes with Arraylists as shown below.

I have this form filled with data using dataset, data adapter
1 Dataset , 8 data adapters
Textboxes are ok and binding .. fills by 1 data adapter
ComboBoxs are filled by 7 data adapters
The problem is 6 ComboBoxes data is from one table filtered by id1 i.e.:
cmb1 : select id2,content from table2 where id1 = 1
cmb2 : select id2,content from table2 where id1 = 2
cmb3 : select id2,content from table2 where id1 = 3

Now how can I bind all ComboBoxs with textboxes?
I have an edit Contact Form that pulls data from access and loads it into textboxes and comboboxes.

I have been setting DataSource for a series of combo boxes to the same table as they all display the same options. However, when I ran the project, any change in any one combo box makes all the others 'flip' to the same selected value. This is obviously wrong.
In Access, you have 'Control Source' which is the db field that is bound to the combo box and 'Row Source' can be a query or whatnot that several combo boxes can run 'independently'.Is there an equivalent option in VB.NET? I DO NOT want to manually enter the exact same options many times as that is hard to maintain, to say the least.
Just to repeat: it is not going to work to say DataSource = Row Source. if two combo boxes are set to the same data source, a selection in one automatically makes the other one select the same value. unless, of course, i am missing something.
I have three comboboxes in a form. The first is the parent of the second, which is the parent of the third. When they are all updated, a datagridview should be updated.
The problem is that the user can choose to change the value of either combobox, so I don't know which combobox's value is being changed. Therefore I now update the datagridview from the third combobox's selectedvaluechanged event. This unfortunately means that if the first combobox is changed, the second and third comboboxes selectedvalue events must trigger. As a consequence, when the first combobox is changed, the datagridview is being updated about six times (which doesn't work for me performancewise).
What I'd like to do is to call the updatedatagridview sub from either one of the three comboboxes, but only if the user has chosen to change that specific combobox's value (that is, get the form to only update the datagridview when the selectedvalues of all three comboboxes have been set).
Background: I have an web form that autpostbacks a list of bundles to a listbox based on the carriers selected. When Postback happens, all user entered data is cleared. How do I prevent the AutoPostback function from clearing entered data from the forms? [code]
View 1 RepliesHow I can populate a combobox (combobox2) based on the selection made from another combobox (combobox1)? They are on different forms. Combobox1 lists locations, while combobox2 lists offices for each location. I would like it to work so that when the user clicks on combobox1 and makes a selection, the 2nd form loads with combobox2 showing all the offices for the selected location.
View 6 RepliesI'm trying to detect when the tab key was pressed and intercept it in certain cases. Since the form I'm working with has many fields, I've tried overriding ProcessTabKey so that I don't have a separate sub for each control. However, I've found that after adding a simple ProcessTabKey method, each time I press tab it skips one of the combo boxes. In order to duplicate the situation, using Visual Basic Express 2008, create a new Windows Forms project and add 5 combo boxes to the form - allowing each to automatically get an incrementing TabIndex.
Then add the following code the form:
Public Class Form1
Protected Overrides Function ProcessTabKey(ByVal forward As Boolean) As Boolean
MyBase.ProcessTabKey(forward)
End Function
End Class
Now when you run the project, you'll see that each time you press tab it skips one of the combos.
this is a subset of a previously posted problem, I have narrowed down my issue and am reposting a question from this thread: [URL] I have apparently confused the compiler by renaming some comboboxes in Visual Basic .net express? (See relevant code below) I think the confusion is in who should handle what, with two routines named with variations of ComboBox1 and one handling the other ( it confuses me just trying to interpret it mentally):

I have a form with 4 comboboxes and a button. The first combobox is enabled, but the rest of the controls are disabled. When the form is opened I fill the first combobox (cbxMethod) with a datatable. When the user selects something in cbxMethod the next combobox (cbxStudy) will be filled and so on. When the last combobox (cbxAnalyte) has a selected value I want to enable the button and give it focus so the user can move forward with the program. I basically want to force the user to move from one combobox to the other, until all are filled.I am currently using the SelectionValueChange event, but this event only fires when the user changes the value with their mouse or hits the Enter key, not when the user hits the Tab key.

I have a Macro that prints Sales Vouchers, is it possible to attach the userform to an Email or write it to a file for later attaching to an email or even send the UserForm to Word again the aim is to transmit the voucher electronically rather than paper. My code at the moment is very simple: UserForm2.PrintForm which prints the form. I tried printing to a file but couldn't get it to work. I am guessing that printing to a file is for Text only and not bit by bit.
