I have a Windows Form in a VB.NET program with a property of "TournID". The ID will be passed in when the form is created by a button pressed. Here is the property stub:

How do I name a variable depending on what is in the textbox?
Like would it look like:
Dim (textbox.text) as string
etc.
The reason I want to do this is because the user is gonna click a button to create a task. When the button is pushed, a label is created by the code I already have, the problem is, I want them to be able to click the button more then once and new labels will appear below the one that just was there. By being able to name a variable by what is in the textbox, I will be able to do so many things.
I have DateTimePicker where user can choose a date and make entry. I then record this entry into the database. My application date shows 08-02-2012 (i.e., 08 february 2012 in DTPicker value), when I select this and insert it to my database, the MS Access takes this as August, 2 2012, and records it as the same.
I could fix this by using this code:
Dim mydate As DateTime
mydate = Me.dtpicker10.Value.ToShortDateString
Dim output1 As String = Format(mydate, "MM-dd-yyy")
and pass sql insert query using
insert into table (mydate) VALUES (#" & output1 & "#)
Instead of getting the value directly from the dtpicker. This fix the issues, but when I tried to get the date out of the database to filter it between entry made in certain date, I sometimes have problem. How do I generalize this for all type of client computers where the date and time settings can be any form. What will be the best and more flawless ways of approach to target all types of clients? Am I on the right track?
I wanna make a program wich starts a .exe I know the code for starting the program : (EXAMPLE)
Process.Start("C:UsersPublicGamesWorld of Warcraftwow.exe")But the program only opens the file when its placed there, is there a way to start it else way?Maby make them choose the file derection ?I know u can make a text box so they have to type it them selve, but can u make it so they have to go through a menu with it ?
Ok so I can't figure out how to make it so that on my application users cannot just click "submit" without choosing a radio/option button & filling out the username + password field ?? Using VB 08 BTW.
View 6 RepliesIn our class in Visual Basic, we are required to turn in a payroll system with time monitoring. And I have prepared already the GUI interface of my system. My question is what kind of collection of data should I use, considering the employee population of 30 (that's what our instructor have told us.)Should I use:
a. Arrays to store them like every field (employee number, employee last name, etc.) has its own array.
b. Sequential files for me to store them in a text file (and if in the text file, could I still retrieve the records inside that text file.)
c. A Database.

I have been trying for days now how to create a process to the user to easily create a connection to any installed data types they have installed. I have found an example right inside vb2008. I never use this because I code my own connections, but this would be real nice if I could include it or duplicate it.

I'm trying to make a program that will open a first-run form when the program is run for the first time. I'm planning on just using a setting in My.Settings.VariableName to keep track of the boolean value. My problem is that I cannot figure out how to choose what Form to open.
My first instict would be to use a Sub Main() as my program instance, and then choose and open forms from there, but I can't find a way of doing it. and Many a post suggest not doing it.
Second I tried using ApplicationEvents Myapplication_Startup, but this makes the form pop up before my splash screen, and doesn't stop my main form from showing.

I've written a program that brings up a form with some radio buttons for the user to choose.The form is setup by a sub in module1 (called Type2Q, shown below).

I want the program to randomly choose one of those thirty questions and NEVER choose the same question in the same program run. By the way, there are four options on my project: A, B, C and D.

I have a program for school project that has input fields for Name, Address, City, State and Zip. I need to error check so that the fields are not empty.I have used If statements that check to see if the fields are empty and shows a message box if they are but if I leave the whole form empty and click the button that activates it, all the if statements go- one by one instead of pausing for the user to input the required data.How do I check for data and make the program stay there until the data is input? I have tried TRY/CATCH but it won't catch this type of error.

I am using Visual Basic express to create a serial interface to a multi-room audio controller. I have started by creating a form that can connect to the controller and I can receive data from the Controller and display Zone status, volume etc in corresponding texts box thaks to help from Stanav and Tassa in my previous thread.
My next problem is to do with receiving lots of data from the serial port and my application getting out of sync. This is mainly caused by turning the volum control as each time it is turned a little bit the controller sends out the new status of the Zone being effected
eg
****Turning Volume knob on Zone 1***
Status returned from Controller:
#Z01PWRON,SRC3,VOL05<CR>

I have read that VB .NET in earlier versions limited the FORM size to that of the development machine screen resolution.I am hoping that there is a way in the current VB 2010 to get around that.However in my attempts to make the form larger, it always resets itself to the screen height on my develoment machine.Is there a way to get around this and have the person be able to use a scroll bar to move down?The data I wish to show actually has two screens worth of information but the stuff in the scroll down section would be used on a limitied basis so scrolling will be useful rather than having to recreat the screen to show less data at one time.
