I'm using VB2010 express and I want to set up my form to have all 22 textbox's start in read only so that my users cannot change the contents accidentally but have a button to enable the textbox's so they can.I know that i can set the properties for each textbox from true to false and back for each textbox but I was wondering if there is group way of doing this or do I need to do each one separately .

In my project, I am trying to change the visible property of my various pictureboxes using a for - next statement. My aim is to get the value of my numericupdown1 control and use this number to make the pictureboxes visible. For example, if this number is 8, the picturebox1, picturebox2, .......8 will be visible. Here is the code I wrote:

How can I call multiple objects? Example..
nameTextbox.Enabled
addressTextbox.Enabled
ContactTextbox.Enabled
How can I call this objects with same properties...
So rather than typing them all with =True or False...
I just have to type a variable = True or false...
And where will I type the code.
I spent a lot of time on this problem. I am able to do simple Group By LINQ queries (on one property) but for multiple fields I'm a little stuck... Here is a LINQPad sample of what I want to do :
dim lFinal={new with {.Year=2010, .Month=6, .Value1=0, .Value2=0},
new with {.Year=2010, .Month=6, .Value1=2, .Value2=1},
new with {.Year=2010, .Month=7, .Value1=3, .Value2=4},

I have a problem whereby I have 10 text boxes and I don't like to use the same code for each and every text box that allows users to input only numbers, which could be very long and messy coding.
Is there any shortcut that I can set all (not just one) text boxes to allowing user to input only numbers?

Using vb.net (vs2005), how do I populate a combo box with multiple property values from an object? Right now I'm iterating a collection of objects and adding the name property of each object to the combo box. I'd like to add multiple properties from the object to the list. For now, I'd be happy if they appeared comma separated in the list.

I'm having trouble getting a numeric format out of a textbox.I can do this in the textbox validating event, but I need commas to be entered into the textbox as the user actually types the data, not after they leave the textbox.. the reason is that they are typing really large numbers and can easily lose track of 0's or the total number if there are no comma seperators.I tried to do this through the keydown event in the textbox, but that doesnt work the comma gets inserted but the cursor goes into the begining of the string so anything new i type goes ahead of the old stuff.is there really no formatting on the properties level of a textbox??? how can there be no datamask?

View 2 RepliesI've created a user control with a simple text box and a corresponding label and added a few custom control properties. When added to a form, I'm trying to loop through all control of this type and evaluate the custom property. In the below, the cntl.MyCustomProperty is not recognized. I can evaluate the property when I check each user control on the form by name, but not by using the loop below. I would much rather use the loop as it is much cleaner.
For Each cntl As Control In Me.Controls
If (TypeOf cntl Is MyUserControl) And cntl.MyCustomProperty = "ABC" Then
''Do some stuff
End If

I have a program that someone else designed the form on and sent to me to populate the code. I am not sure what could have been done to cause this problem, hoping for a quick oversight on my part. There are several fields of textboxes that the user enters numbers in. Normal behavior for textboxes is when you tab to them the current contents are highlighted. On one of these textbox fields, and only that one set of textboxes, the contents are highlighted like normal at first, but after the user edits the content of the textbox, if you tab to it again it will go directly into edit mode instead of highlighting the contents. Each textbox in the field does this individually, so if you just edit one, all the rest will continue to highlight contents until you edit them as well. It appears you don't actually have to change the value of the textbox, just entering edit mode and getting a blinking cursor is enough. I cannot find a difference in the properties of these textboxes compared to the rest.

View 2 RepliesI'm making a control and I am trying to finalize my design time properties grid. I have several List(of Class) items as public properties and when I click on the design time menu (while testing the control) there is the word "Collection" and a button with an ellipsis (...) that brings up a neat pop up with the buttons Add/remove and all of the public properties of the collection's class on the right hand side. Basically for a non-collection instance of a class (with public properties) I'd like a similar button to show up. I know I could put all of the properties in the main control class and group them, but I like the pop up box feature. Anyway to duplicate this? (think font grid item etc.)
View 3 RepliesIn the form design I set up a TableLayoutPanel, 20x20 cells and in cell (1,1) a PictureBox (called Target) containing the image of a small target. The properties box for Target shows some very promising properties, Column and Row - and if you overwrite the values in the properties box, the PictureBox obligingly shifts to the corresponding cell position in th design. However in VB it is not possible to refer to Me.Target.Row or .Column - neither appears during coding in the menu of properties, and deliberately coding either of them produces an error like
Error 1 'row' is not a member of 'System.Windows.Forms.PictureBox'.
1. Why does the properties box show properties that cannot be altered programmatically?
2. How can my program move Target around in the TableLayoutPanel?
I think this will be better than what I was thinking before.
