Is there any way to refer to a button by using string?For example: I want to set a value on specific buttons only, the naming convention is, btnA0, btnA1 etc.. So in a for loop I want to be able to change a setting on each pass. Basically something like: btnA+"string variable here".visible=true.The variable for the second part of the button name is actually an integer, I hope I have made my problem clear.

View 1 RepliesI have a simple windows application that pops up an input box for users to enter in a date to do searches.
How do I identify if the user clicked on the Cancel button, or merely pressed OK without entering any data as both appear to return the same value? I have found some examples of handling this in VB 6 but none of them really function in the .NET world.
Ideally I would like to know how to handle the empty OK and the Cancel seperately, but I would be totally ok with just a good way to handle the cancel.

It will ALWAYS have the "COMMAND" string there no matter what, and when the "DATA" string

I would like to recreate the behaviour of a button or command button on an user control. I need to layout a group of this user control on a form so user can select only one at a time. When users click on one of this user controls a selection frame is drawn to indicate that it has been selected. The problem I have is clearing the selection frame when other control is clicked on. How do buttons or command buttons do this? If you layout a group of buttons only one is highlighted. I have tried using different events like LostFocus and Leave and nothing seems to work.

View 2 RepliesI have a radio button control on a web form. The members of my ListItem collection are
assigned the following.
Text No
Value 0
Text Yes
Value 1
So what I need to do, is to readd a varchar value from my database and if the column value returned equals 'Yes' then I need to select the radio button that has the assigned value of 1. Otherwise if the value read from the database is 'No', then I need to select the radio button assigned a value of 0
So how can I set the value for my radio button? I experimented and could not figure it out. The 'Yes' or 'No' value is stored in my database in the field ds.Tables("employee").Rows(0).Item("answer")
So I tried something like this which is not correct:
RadioButtonList1.Items.FindByValue(ds.Tables("employee").Rows(0).Item("answer") = "Yes").Equals(True)

We are trying to identify the best archtecture while using a ORM like LINQ to SQL. The archture we are defining is for sort of framework that other applications will access either trough directly referencing the DLL or through a webservice. We have .NET apps and PHP apps.The possibilities are: Multiple data contexts: Separting the database into units of work and create separate contexts for each one.
Pros:
Easy of use
Classes will be broken into different namespaces
Smaller domain to maintain
Cons:
Objects have to be duplicated if
related, creating maintenance hell
Objects cannot be passed between context, creating the need for another hit on the data base Single data context: All tables, views, procedures, reside in the same huge context.

I have a large string in which I need to replace specific strings with other values. For example, within this string I might see the following characters: [[sub id=5]]. I am trying to replace those substrings with values, pulled from a table and based on the id. What would be the simplest way to accomplish this. My first thought was to loop through and examine each character and note their positions when they match the pattern. I would then have to identify the id. That would be fairly complicated, however, and there must be a better way.

I need to identify an ID number and a password. Like this,(Form1) there's a two textboxes, one is the ID number and the second one is the Password, when I enter the two it means i Log-in, the system needs to identify if the ID number and the password is registered in mySQL, then if it is registered a message box will appear "You are log-on" and a form will show (form2) in 10 to 15 seconds that is having the information of the student, then it will automatically close then it will go back to the form1 which the another user will log-in again.
(this is Form1 too) then here is my second problem, like what i said in the first problem, the program needs to identify that the student is already log-on the school and he is going to log-out, (like this, system is going to identify that the id number and the password is already declared on the first form, so it will be the log-out code, then a message box will appear "You are Log-out".
(Form3) then here is my third problem, i need to identify how many people is inside the campus and not going out on the campus. The person or student that is not logging-out on the program or the system will be count when i click the Button 'Count' and the number of student inside the campus will be display in a 'Label'(it will be inserted also or having record on mySQL tableInside).
('Form4') then my fourth problem is the system needs to identify how many students did log-in on the campus. Or the system will identify how many person input their ID Number and Password on the first form ('Form1', it will be inserted or having record on mySQL tableLog).
Let's say i create 3 different process like this:
For i = 1 To 3
im pr As New Process
pr.StartInfo.UseShellExecute = True
