Greetings, I'm sure there's a simple solution to my question, but I haven't figured it out yet. I have a Form with 12 Label objects L1-L12. I'm trying to set the ".Text" values of those label objects with the values of the fields in a Database table,,, Here's what I have. It DOES NOT get errors. But it doesn't work either.

I am attempting to dynamically create a profile page. Everything works fine except when I try to add the title (surrounded by <h2> tags) to the lbl control which is inserted in the select statement. Let me know if this is too confusing and I will attempt to explain further.

I've been working at this for hours, and I'm completely stumped. There may be a more elegant way to do what I want, but I can't find it in my reference books or online. I have a form that has 64 labels corresponding to 64 unique locations on a map. Each of the labels contains one character, a ●. The program determines, randomly, if these is something in those locations.'m using a For... next loop to step through each location and determine if there is something there.My question is how do I turn off the label in the form without resorting to some 64 choice Select Case statement (or something similar).

I have only 1 Label in my form. There is no text in Label1. I want that when I run the project, the label has any word or number in it like '1'. I want that when I run the project again, the word or number in the label should be changed to '0'. The name of my label is Label1.
View 8 RepliesI'm programatically creating labels in programatically-created panels, and have run into an issue--the label's information isn't completely showing! COnsistently only the first few characters are consistently displayed. I've tried bringtofront, but it doesn't work at all. And the characters stop well short of the panel barrier--does anyone know what to do about this? I used messagebox.show(labelname.text) to make sure it wasn't working properly, and sure enough all the characters I want are in the label, but aren't appearing.

How would I create a label that reports a file size at all times? Or, on a regular basis, say every 10 seconds or so.
In my form, I want a label to watch certain file sizes (logs, etc.) in case one suddenly becomes too big.
It is easy enough to report a static file size when a form launches, but changing it dynamically...I don't know how to do that yet.
The following example is generic and simplified for illustration purposes.
The file is C:Applicationapplication.log
The label might include:
("The application.log file is {0} bytes.",GetFileInfo.Length)
or something like that. But that would report a file size once and never again unless I quit and restart the form.
If any .NET concept is used, can you provide a link to the documentation or msdn stuff?
Is there a way to change label text at run time?. I don't want to annoy users with popup. So planning to display error in a label if its text could be changed.
So far I have included a Main Form which has a label lblErrorFeedback which is not visible initially and I have done this but does not work.
lblErrorFeedback.Visible = True
lblErrorFeedback.Text = ""
lblErrorFeedback.TextAlign = ContentAlignment.MiddleRight
lblErrorFeedback.Text = "Error Occured"
Is there a better way to show the error with out popups?
I have several group boxes on a winform. within each there are several labels.I am accessing the group boxes with no issues but I can't seem to find a way to update the labels within by looping. They have the same name except the last character which is a number 1 - 9. ex. lbl1, lbl2 ... lbl9.I need to update the text of each label in code with text I get from a database ex. lbl1.text = one, lbl2.text = two etc... I want to loop through the labels to assign the text. Getting text from database is no issue what I am not doing properly is getting the labels.
do while QstNum < 10
Dim ln As New Label
ln.Name = "SC_Cat" & QstNum

I have the form with a tab control on it, there are 5 tabs each with a label contained in the tab-page.I want to have a button outside of the tab that changes on the form. when clicked the button will change the text of the label based on which tab is currently selected. I know it should be possible to do this, I'm not too sure where to start.
View 2 RepliesI'm making a button that will create a textbox, and label dynamically.
I have it creating both, but when I try to set a font on the label, it disappears.

When I remove the line that sets the label's font, it shows up, but in the default font.
I am adding controls to a page programatically in the code behind. I add an asp:Label and set it's Text value. I add an asp:TextBox and set it's Text value. Both Text values are returned in the Response and displayed in the browser. All fine so far.
The user performs an action that causes a postback. I re-load the dynamically added asp:Label and asp:TextBox. When the Response is returned to the browser, only the asp:TextBox Text value is displayed. The asp:Label Text value is not. If I inspect the HTML I can see the asp:Label control (rendered as an HTML span tag) but no value.
How can I get the code to automatically re-load the Text value of an asp:Label on each postback? Why is the behaviour different for an asp:Label and an asp:TextBox? I do not want to have to manually re-set the Text value on each postback.
Here is some code similar to what I am doing (placeHolderNameplates is an asp:PlaceHolder control on the aspx page): Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init

does anyone know how to connect points of a label? Let's say I have a label and start the label at point 0,0. Aterwards, the points jumps to 3,6 ... then to 6, 9 dynamically based on incrementing 3. How do I show for example, the path it takes to let users know where they are? for example, 0,0 --> 0,3 --> 3,6 --> 6,9 --> etc. I've tried with drawline but unfortunately, this leaves my lable in a mess.

Create a generic label method:

For some reason, the label is not lining up with the others once I span it. I'm trying to span it to get all the text to show but once I do, it starts pushing it over. I don't see anywhere where I restrict the size so that shouldn't be the issue.
I tried doing all this in the design and it works just fine. Mimicking the designer code doesn't seem to fix it either unless I'm doing something seriously wrong...
Posting images for clarity. NOTE: The borders are just to show the label alignment and the text should read "Flat-Footed AC"
IMAGE 1: Spanning 1 column (doesn't show all text)
IMAGE 2: Spanning 3 columns (still doesn't show text and you can see it's starting to dis-align)
IMAGE 3: Spanning 6 columns (Still doesn't show text and greatly dis-aligned. It should at least show all the text)
How can I do this:
Dim oMyObject As New MyObject
oMyObject.DoSomething("Parameter1","Parameter2")
The "DoSomething" and the two parameters are dynamically provided from another script. They are stored in a string object in this script: sAction & sParameters. My question is how can I dynamically pass the "sAction" to the object oMyObject.For example oMyObject.sAction (where sAction should be the value stored in the sAction string). The example will probably not work. Is there a way to do this? The idea behind is to avoid having to write each function hardcoded, like:
If sAction = "DoSomething" then
oMyObject.DoSomething(sParameters)
ElseIf sAction = "AnotherThing" then

Is It possible to get the arguments' values used in the previous execution method?
For example:
Public Sub GetPreviousMethod()
Dim stackTrace As StackTrace = New StackTrace
Dim stackFrame As StackFrame = stackTrace.GetFrame(1)
'MethodBase: Get the previous method
Dim methodBase As MethodBase = stackFrame.GetMethod()
End Sub
If I use 'methodBase.Name', It works 100% and return the method name. I got the arguments' names of this methodBase using Reflection, and is It possible to get dynamically the values of the arguments?

VBE 2010, and I'm hitting an AccessDB
I am writing a mvc 3 application and part of its function is to send out confirmation emails along with an assortment of other emails.. I have the body's for the different types of emails stored in a database table.. Getting the values out of the table and dropping them in a email body using System.Net.Mail isnt a problem at all... What I need to do is somehow put somekind of variable marker in the body which is in the database table and then somehow parse the body text when its dropped into the email body to find the variable marker and put the correct value in it's spot..Code snippet of what I have so far is below:
Keep in mind that this will be a rather large body and there are a few places values will have to be dropped in.. I was thinking of having it use something like this:
Long mail body ^^Name^^ has been approved for classes starting on ^^Date^^ at the ^^Place^^ located in ^^Location^^..
When the code loades the text from the body when ever it comes across a variable marked with ^^ it would put the correct information in its place...
Dim _content As email = db.emails.Where(Function(f) f.ref_name = "Confirmation")
Dim _body As String = _content.email_body.ToString
