Using this
TxtBox = New TextBox()
With TxtBox
.Name = "T" & reader("area").ToString
.Visible = True
[code]....
The name would come out like "T3" Now I want to put a value into that textbox.How can I address the correct Textbox?
I have created a basic query generator which allows a user to select the Select, WHERE and criteria attributes using a number of checkboxes.However i have got stuck. In the results form i have the following code
Private Sub DisplayRecord()
RichTextBox1.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(0)
RichTextBox2.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(1)
RichTextBox3.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(2)
[code]....
The program keeps on crashing if the user does not select the corresponding amount of display records from above for the amount of attributes they want for the SELECT part of the query in the intreface in form 1.
How would i go about making something where the number of SELECT attributes selected which are listed in a string create the correct number of textbox fields in the results form (form2)

i am trying to automatically generate multiple text boxes on a form with the following code

Do Until y = x

View 10 RepliesLately I have been making a program (I guess you could call it a trainer), which would read the process memory to get the character's coordinates in a game. It later makes a simple map and show it in a separate windows. I built this program in VB.net, and it works surprisingly well. The only problem is the fact that the memory address where the coordinates are stored, changes every time I restart the game. Could someone please help me find a way, for the program to find the correct address by itself? If it helps, the game I am referring to is Minecraft.

I am new to vb.net. I created a vb.net script to autogenerate a code. Now, after generating this code, what I want is to determine the validity of this code. for example, a code has been generated now and this code will be valid for 24 hours only.
Below is my script for the auto generation code

For i As Integer = 0 To 9999
randomhold = randomvalue.Next(1, 9999)

Next
The code generated will be sent via sms. If the code hasn't used within 24 hours, it will be invalid.

According to the General Naming Conventions the usage of CLR type names (e.g. String, Int16) should be preferred over the usage of language specific type names (string, short). I usually follow this advice. Resharper however seems to use the language specific type names when generating code (eg. when extracting methods or generating foreach loops) which is very annoying.
