VS 2008 : Timer Code For VB6 To VB2008 - Error1Name 'StartTime' Is Not Declared
Jun 10, 2009
This timer code is for VB6 and worked fine, It's to change the timer seconds into minutes, I'm not sure how to make this work for 2008 though.
Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Timer1.Interval = 1000 ' set timer to 1 sec intervals.
Timer1.Enabled = False ' timer is off
End Sub
[code]....
the errors are...
Error1Name 'StartTime' is not declared.
Error2Name 'MinutesToWait' is not declared.
Error3Name 'StartTime' is not declared.
I am using visual basic 2008 express edition.I got some error message.
Error1Name 'numcourses' is not declared.what is means?
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click If [b]numcourses[/b] >= 8 Then MsgBox("You are only allowed to enter 8 classes", , "Error") Exit Sub
I'm trying to add CheckBox1.Checked = True to my .dll but i get this error. Error1Name 'CheckBox1' is not declared. But it the client app it is declared.
Quick question - if I have a timer set to 5000 (5 seconds) and the code in the timer takes longer than 5 seconds to run because of sql stuff, will the timer wait until the code is done till it fires again?
I get like bunch of msgbox and when i break point the timer dosn't go to the end it just reach to the msgbx and then repeat again from the beginning , i dont know why, i removed the timer and made new one but still the same problem.
Out of curiosity, is there a way i can make a program stop or pause for a period of time (which i would choose) before continuing the code WITHOUT a timer.I think I've seen this done before, but I'm not positive.Also note that I'm talking about a forms application (not a console app if that would be any different.)
I'm writing some VB2008 code to control four 7-seg LEDs I bought from Velleman. They came with some example code in VB 5.0, and with instructions telling me to input 5 bytes at a time in the format Chr$() & Chr$() & etc. for the rest of the 5 bytes. When I try to do this using VB2008, it rejects the $ sign, so I've tried it using the Chr() format, which VB2008 allows. However, it doesn't work. Is Chr() the new version of Chr$() or are they different entities? In sending data to the LEDs, I'm using LiveComPort.WriteLine() as my command. (My serial port is called LiveComPort) I also tried it with LiveComPort.Write() asthe command. I know that my serial port and the LEDs are working, because they respond to the demo program provided by Velleman.
I've run some code which extracts data from a database and presents it into a Datalist. It works fine when the script is on the aspx file, but when I transfer it to a code behind I get the following error
Compiler Error Message: BC30451: Name 'showIt' is not declared.
(showIt is the ID of the Datalist)Obviously, the Datalist markup is in my aspx page, and the script is in the code behind .vb file.As I say, it all works when the scripts are all on the one .aspx file.The code in the code behind is: (I've skipped the SQL and connection strings to keep this post concise)

Using VB 2008:Situation: A Form1.BackgroundWorker calls a Form1.subroutine. That sub starts a Form1.Timer with Me.tmrOK_BlinkForm.Enabled = True...fires Timer code in event: Public Shared Sub tmrOK_BlinkForm_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles tmrOK_BlinkForm.Tick
There must be a way to do this, I just need the correct BackgroundWorker Syntax send Stop commad to Form1.Timer from Form3.Click_event...all inside a Form1.BackgroundWorker thread started in Form1.
I have a code in VB 6 but doesn't in VB.NET. Even I was converting, but, there's a thing that I can't convert because I don't know what "hProcess" means .
I am attempting to make a tabbed browser and I am getting a couple of errors. First one is "name 'addtab' is not declared" the second is "reference to a non-shared member requires an object reference" the third is "statement is not valid in a namespace" and lastley "the resource name 'stop' is not a valid identifier"
I am trying to get a subset of locally declared methods in a webform code behind using GetMethods but cannot figure out the proper BindingFlags settings (see code below)....and some further specific questions:
1) Is it possible to differentiate between Procedures and Functions?
2) Furthermore, I only want to fetch a certain subset of these....is there some way I can decorate the ones I want with an attribute, and then further filter based on that?

In vb6,I wrote those code: statusbar1.text=Inet1.Open[URL]
In vb2008,it had statusbar,but it hadn't "Inet",I don't know how to change those code. ps:I'm a beginner,maybe this problem it's not a big problem,but I really don't know how to solution this problem,
We have an old large program generated using vb6. This has been running for years and it works great.We would like to migrate/ upgrade to vb 2008, is there any fast way to have it running under vb 2008?I loaded the project in vb 2008, it did load but generate a lot of errors and warnings. how can i migrate the vb6 codeto vb 2008 easily?
i want to create a basic calculator. i can create it in vb6. but when in vb2008. it have problem.. how should i do this?i just need help for + and - .. then other i can done it le... y i can use dim at vb6 but when i use in vb 2008 .. i can't use.. the array is same also... seem like quite different vb6 and vb2008...

I have forgotten the right procedure to encrypt the VB2008 code with dotfuscator community edition, may you explain the way to use it (the dotfuscator) step by step?
How do I go about writing facial recognition code for a program I'm designing? I'm using Visual Basic 2008 Express Edition and I need to implement facial recognition into my software.
I am converting a VB6 program to VB express and am having a couple of problems. One of them is a difference in String use. "Result=string$(32,0)" doesn't compile and I tried the trim function, but when I cannot use the "0" with the trim function the program shuts down with the error "Argument 'Start' is not a valid value." I need to replace the "Result=string$(32,0)" with a valid vb express line.

In re-engineering a windows forms application, I find that a lot of code-behind in the various form classes is duplicative and I'm trying to centralize as many procedures as possible into a base class which can be inherited and used by the subclassed forms.
This process seems to be going well and is making the code in my subclasses much simpler and hopefully easier to maintain, but I'm not sure where to draw the line between leaving code in the subclasses and engineering for generic resusability and moving it to the base class.
Specifically, in some subclasses I have code which manipulates variables and objects specific to the subclass, and although I could move the code-behind into the base class, the base class code references specific objects which are needed to compile. For example, each subclass manipulates a databound datagridview and form detail controls which allows the user to select between multi-record and detailed single-record views of a datatable.
In Visual Basic 2008 do I need to declare dummy data objects in the base class so that the base class will compile? Or is there a way to indicate that the data objects will be provided by the subclass?
