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.
For Each TextBox In GroupBox1.Controls
TextBox.Text = ""
Next
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 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 Repliesso 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
When 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 RepliesOn my form, i've got some textboxes and some richtextboxes. I'm using the following code, to search through the text properties of each of the two types of control. see below:-
For Each ctl As Control In Me.Controls
If ctl.Text = "7777" Then
ctl.Text = "found the sevens"
End If
Next
What i'd like to do is isolate the textboxes only, is there a way to do that? I tried this but i got an error:-
For Each box As TextBox In Me.Controls
If box.Text = "7777" Then
box.Text = "Found"
End If

I have written text to a form using DrawString but now want to clear the form and reset the "next" writing position to the top of the form display area. BTW This is NOT a text box!Using Me.ResetText() clears the text from the form but does not move the position back to the top.

View 1 RepliesI'm trying to make a game logger for MW2 so you can enter different stats and it will display those stats along with like your overall KDR for those matches and what not.Right now I'm just trying to do one match at a time meaning you enter your kills, assists, and deaths you hit the enter stats button then you hit the display stats button and a bunch of info shows up in the list box. Then you re enter different stats and it gives you the same stats but updates them for that match only. However, for some reason the list box isn't updating. It just keeps adding the kills, assists, and deaths together however the KDR does update.

View 1 Repliesis there a way to select a range of cells in a worksheet and clear the data in them?i DO NOT want the WHOLE ROW to be deleted, only a few selected cells (they are all adjacent to each other)and i don't think the ActiveSheet.ranges method works as:
1) the coordinates of the cells in the row to be cleared are determined logically by a VBA sub, i know how to get the coordinates, just dunno how to delete the row
2) this needs to be applied in different areas of the worksheet AND across OTHER worksheets as well.
I'm quite sure I have the logic needed to find the coordinates just need to know how to clear the cells if there is a way to do it that is similar to ActiveSheet.cells ( row, column ) then it would be best from my understanding the ranges method only takes in letter and number formats in strings... i need something that takes in number and number?
Is there a way such that I could reset/clear the values of the controls in my form no matter what type of control they are, can be controls from control suites like Janus and/or ComponentOne?

The problem is that the textbox for age resets to 0.
