View 8 RepliesCreating And Editing An Array Of Labels?
Nov 18, 2008i am attempting to create and then update data in Labels using VB2005.I create the label when the form is loaded using this for loop
For j As Integer = 1 To count
Dim name As String
Dim m As String
ReDim L(count)
[code]....
This creates the labels and text boxes in the form. Later in the program I would like to change the text within both the T1310() and T1550() text boxes and I am attempting to do so with the following code.
For j = 1 To count
status = OP930_SelectModule(j - 1)
status = OP930_SetWavelength(1310)
[code]....
I get errors on the Blue lines. Everything compiles fine, but when the software goes through the loop I get the error "NullReferenceException was unhandled"

View 3 RepliesEach Loop In Which 5 Labels Should Be Created?
Mar 21, 2010I'm trying to have a for each loop in which 5 labels should be created.Each time the loop restarts the 5 labels should appear in a tabpage.The problem is, it only makes a label once, then it keeps on mving the label to a different tab instead of creating a new one for each tab.
It loops 5 times, thus filling 5 labels.Then the next 5 labels should get filled in a new tab.But it just moves the original labels. How do I force it to create a new label each time?

Accessing Dynamically Created Labels - ASP.NET?
Apr 28, 2009My current project involves displaying questions/answers from two different databases to be used to compare values and make judgements. The number of questions, choices, and answers is all variable. Thus I am attempting to create labels dynamically to show the information on the screen and create textboxes to leave comments. My problem is not knowing how to then access these lables, since I can't code in to use "label_comments" & (i) as it doesn't exist (at least, I can't get it to work).
First, my code for creating and displaying the information:
db_connection = New SqlConnection(ConfigurationSettings.AppSettings("ConnectionStringMerrill3"))
db_connection.Open()

Created A Form With 2 Labels 2 Textboxes And A Button?
Feb 10, 2009I created a form with 2 labels 2 textboxes and a button. Basically it is a login from. When I launch the form it shows the blinking cursor in the 1st textbox(this is ok) but when i try to type nothing happens. Once i click the form(not the textbox-textbox works too but wanted to note it was the form) it works. I have tried doing textbox1.focus(). I have tried doing the form.focus(). Neither were successful. It may have nothing to do with focus but it seems to be that to me.
View 12 RepliesDelete Dynamically Created Labels On Postback In Asp.net?
Jul 6, 2011I have a form that has an array of dynamically created labels of varying size based on a search from a database. The problem I'm having is that when the user searches for a different term, it looks like some of the labels don't get new values. Here's my code for adding the labels:

ReDim Preserve entities(cnt)
While rdr.Read()

I've tried for loop over the controls in panel1 to dispose of any still on there in both the page_load and page_init subs, but neither had an effect. I don't know if it might have something to do with controls having the same IDs after the postback.

Which work fine, but if I want to create another label, how do I check to see if one or more labels have already been created and then apply a new location of the new label? (so it doesn't get override on the same location on the form?)
Creating Sequentially Named Labels?
Oct 14, 2010I am using a variation of Stanav's example from the previous post seen in Sub dd_Inhoud_Labels. The first 3 Subs (Add_Titel_Label, Add_Byskrif_Label & Add_Lewering_Label) is allso shown below so you can see what I am leading up to. Sub Add_Inhoud_Labels is not only responsible for creating labels but allso placing them acording to the location and size of the previos label and allso ather properties as Font and so on depending on the marker at the start of the text string saved in the data base.The problem I can not get solved is that only the last of the Inhoud Labels seem to be created, it seem to be in the correct location as last label as seen in the pic below
View 3 RepliesDynamically Creating Labels In An If...then Statement?
Oct 20, 2011This may be simple, but im having a tough go at it. I'm trying to make a "review" section in a step through form, where the user can see everything that has been entered and if they choose go back and "edit" that information again. One section only has to show the information that has been added by the user, basically if they don't select a certain checkbox there is no reason to display the info for that box.I want to to dynamically create labels in a Panel (Panel7) on a TabPage (TabPage3), only for the checkbox information that was selected. This is what I have right now, and I am unable to see anything on the page, I have also tried without the panel and straight onto the tabpage itself to no avail.

Forms :: Creating Labels That Can Be Dragged Around Dynamically?
May 9, 2010I'm currently making an application that involves time tables / scheduling. I'm required to generate a timetable for school teaching activities. in this application, I want to display the time slots using labels and I want to enable users to drag them around to place the subject cards in the available slots. I'm even confused with the control to use for the time slots. Right now I'm thinking of using datagridview for the time slot. So I'm trying to drag the labels around and placing them in the datagridview cells.

May 4, 2011I have a IF statement which is checking each row in the data table (for a match) and ELSE statement with commands which are executed if the If statement is not satisfied. Now I would like to write like so that it goes to the Else part BUT ONLY for values which are not satisfied in the IF statement. If I am more specific; I would like to calculate values if a match is found and just print them if it is not fond (usually there are both cases). Now the problem is the bold text; if there is a match found I don't want it processed BUT if the match is found I do. How can I write that?

View 9 RepliesArray Of Labels - Converting String Into Object
Apr 2, 2012So, I'm creating an array of labels. I have labels set up as:
labal1
label2
label3
etc...
I've declared the array as such:
Dim labelArray(5) As Label
Now, instead of assigning the labels one by one to the array (labelArray(0) = label1, labelArray(1) = label2, etc...), I was hoping to use a loop (there will be more than 5 labels). I have something like this, which obviously doesn't quite work:
For i = 0 To labelArray(i) = "label" & i Next
Is there a function that I can use to convert the labelName string to an object, or have vb.net see that as an object instead of a string?
