View 1 RepliesI'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 am working on a form with several databound textboxes, each with its own label to identify it. I would like for the label to enable/disable based on code logic. I see the label properties in design mode, but cannot access the label properties in code. The intellisense tells me my label name is not declared. Am I not able to access label properties as in vb6 or the same as a textbox?
I have never dealt with dynamic control events before. I have a variable number of a controls each created at runtime. However I don't know how to code events for each control as they should do different things. I've looked at WithEvents and AddHandler and know I have to use Sender however not sure how to use /where to put eg. MouseEnter 1 panel when there's several.
View 5 RepliesThough I know your site ask for some effort on my part im not exactly sure where to start.. I know how to code some decent things and such but recently I wanted to make a serial code system.. What Im looking for is to have a list of Serials on my website (possibly through MySQL? Or something simpler Not sure on this either) I know about the obvious
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If TextBox1.Text = "BLAH123" Then
MsgBox("Valid Registration key. Thank you")
[CODE]...
But I do not like this system as I have no control over multiple uses. I want to pull the keys from my website (hell through a notepad if its easier) therefore allowing me to delete and add serial keys as needed..
How to use this code working if i use web user control of asp.net ?

I'm working on an application that uses a control with up, down, left and right user bottons to move a box in another control (another form). I know the name of the control. If I place the buttons in the same form, I'm able of keeping the focus on the control that have the box, by using:cvsDisplayControl.focus()
I tried to compile the control with this instruction within the code, but I got a errors since this the display control is not part of the one that has the buttons. Something that can help me is a way to assign tha name of the display control in runtime or read it from a file so the control can be compiled ok.
Here the code behind... I'm trying to retrieve this control so I can add items to the drop down list (I'm retrieving the Role Groups to add to the drop down list in the code-behind)

Just about every day as I build my app and run/test it, I click on a control (button, grid, anything) and nothing happens.I double-click the control in design mode, and it's like clicking on a new control, no code is there.It turns out that the control loses the part of the line of code.[code]This has happened so often that I know I'm not deleting it accidentally.

I have a lot of ListView control on a form and I'd like them to have the same Click event . The problem is that I would like that be done by code . The reason is not only that they are many so it would take time to select them all one-by-one , but also in the future I might add more or even change the name of some of them . So , is there any way that we specify (by code) an event to be the Click event for all of the ListView controls , no matter how many they get to be and no matter what their names are ? The editor I am using is VS2008 , not VS2005 that I specified in the topic's name .
