how to do something similar to what was a control array in VB6 in .NET? I would like to be able to fill the contents of several text boxes using a FOR NEXT loop or something similar..... corresponding the contents of an array with the texts of an equal number of text boxes.
[Code]...
I am trying to port a program I wrote with old VB 1 and I have many control arrays in the program, and it was so easy to do this in older versions of VB, now I am trying to find how to do this and all the answers I have found are a major productions, to replace something that was so easy to do? I would think that microsoft would make programming easer with each new incarnation. instead they are making it harder. doing away with the DATA and READ statement, now it is much harder to fill an array with a loop, now you have to enter each item in an array ONE by ONE. they did away with the ON statement, I had several ON statements, I had to make complex Select case constructs. to replace a simple one word statement?
To make an array of controls in OldVB all you had to do is Name a Second control the Same as the First, and a dialog pops up and ask if you want to make an array, you click Yes, and that's it, what could be easier than this?
So as the name states; I am a newer coder.
This is the code i have:
Public Sub RandomNumbers()
Dim s(4) As String
Dim RandomNumber As Byte
I don't know if you can tell what I am trying to do here, so I will try to explain. I what to create for random numbers and place them into for different text boxes. I also would like to do this with combo boxes and their selected indexes. So if the combo box has 10 items in it; the new selected index would be the random number generated above.
I'm trying to lern VS 2010 from VB 6 and one of the things i'm hawing a problem whid is control array.In vb 6 if you create a text box it's named "Text1" and if you yust copy it and paste it it renames to "Text1(0)" and the new one's name is "Text1(0)" and the code would lock like this
[code]...
then it would print for each loop the random result in one of the text boxes corresponding to i.
How do i do this in VS 2010?
I have a series of checkboxes named cbS1 through cbS20 and I set 'Count' as an integer.What I need help doing is taking the value of count and check the checkboxes that are greater than the count.example: count = 7 so checkboxes 8-20 would be checked.Im not sure how to make an array out of the checkboxes to use in a loop.

When the user clicks on the Prodcode, I would like the Prodcode to be entered into a field on the form. at the same time, the ProdName should populate the ProdName field on the form.

I am wondering is there an easy way to fill up text boxes. Lets say, i have a form with 11 text boxes. User puts a decimal number in one text box, hits button and that decimal number becomes converted to binary and i need to fill up all 10 other textboxes with elements of that binary code. My code looks like that:
Dim a As Integer
Dim s As String
Dim aa() As String

My text file is something like what you see below, and I want to populate the datagrid. Once I populate the datagrid, I'll use that kind of like an excel spreadsheet in the sense that I'll dip in and grab values based on row and column index to display to the user. I will also (on a different form maybe) display the same datagrid to the users so they can sort by column at their choosing.[code]The error I am getting is: Value of type 'Integer' cannot be converted to 'System.Windows.Forms.DataGridViewCell'.

What i am looking to do is to be able to save/load all the values filled into a form. For example The user has entered the
name: "Tim"
address: "123 Fake Street"
phone: ""
And then saves. When the come back and load this i want to be able to load it back exactly like that so the can continue with what they are doing. And if there are to open a different person they can continue with that one where they stopped. I want to be able to save them all at once and load them at once.
I think the problem arose because of Windows 7, but when I was at school the program worked. The program fills in the text boxes with information from Microsoft Access. However, my laptop has Windows 7, and when debugged, the information doesn't fill in the text boxes like before. Also, for added information, the school's computers run with Windows XP.

So I'm in the final stages of finishing a program I've been working on for nearly a year now, and this is basically my final hurdle. The Save dialogue is working beautifully, with 'flags' in order to switch it over from the regular input into text boxes to the Listbox input protocol.
However, I'm having a *** of a time getting it to take lines from the text file and put them in the proper text box. Here is an example file:
Quote:
SHOWNAME
CALLNAME
BREED
[Code]....
So with the sample file I provided above, in the textbox named callNameText would appear "SHOWNAME", and so on and so forth. With this build, I get a NullReferenceException on the "Me.Controls(strboxNames(i)).Text() = strAllText(ati)" line.
I have 100 text boxes on another form I have to populate. I don't want to use 100 Form3.txt1.Text = Mid(answer,1,1) as shown below, i would like to put them in a loop, like a For loop. But when I try I get Error1'txt' is not a member of 'WindowsApplication1.Form3'.Is there another way of doing this?

I've got Visual Studio 2010 and I am looking to clean up my code technique, since I've taught myself and now I'm taking classes.
I'm trying to use a For...Next Loop so that I can fill a text box with sequential numbers. For some reason, all I can get in the text box is the last number and I feel that at this point I'm probably overthinking it...
All I want is on the button push the text box shows:

I have an insert statement which works fine but before the record is saved I want to validate the text boxes. So I just need to know how to check for empty text boxes before the save button is clicked on. I have seen a couple of examples like:

MsgBox("empty box")

Is it possible to get all of the text boxes from a Tab control ? I just want to perform an action for all of them (i.e. change their back color).I am using this following code , but it doesn't work.[code]I have also tried to catch the name of their parent control ,but to my surprise the value is Nothing ! It is like they are not placed on a parent control.I have also tried placing the text boxes on a Panel control and then the code works fine (replacing the Tab control's name with the Panel's name) . However I need to use a tab control because I need more than one tab in order to place my controls.Just in case , let me specify that the Tab control is already place on a Panel control .

View 1 RepliesI am facing an important problem with the LineShape control (installed with the Visual Basic Power Pack) . The problem is that in design time once I have "Sent to back" some controls (other controls, like text boxes), I can no longer select them! The controls get stuck on the form and I can't select them anymore! Even if I select those controls from the Properties window, I still can't do anything with them (like move them over the form etc). Right now I am using VS 2008. However maybe this problems doesn't appear on VS 2010?

If I change line 38 to something like (40) from (-1) the program will just hang and eventually an error will pop up because it hasn't responded.

I have a datagridview with 3 columns.
Now I need to fill the datagridview's datasource with 3 arrays.
Example:
(column1) Username- Joe - Mark - Thomas
(column2) Password - Joe - Mark - Thomas
(column3) Activiated - Yes - No - Yes
Then after i split what should I do? Should I add 3 arraylists in a class or should I use structure and how?
