Label Does Not Refresh Properly?
Jul 3, 2009
I am using a timer with 1 second interval, that calls a function (for example) to download a file. So every one second the following happens in the timer.
label1.text = "File " & fname & " downloaded"
label1.refresh
call processfile(fname)
' only if i use application.doevents label refreshes properly.
Now inspite of using refresh, the label does not refresh properly. For example: for the new text you may see the entire text but if the older one has few extra char then you see that also. in other words you see new text and part of the old text. I am so surprised as to why is this happening.In vb6 when we used to use refresh the label used to refresh properly.

I'm trying to figure out how to make a dynamically scaling/resizing 2d chart on a form as my 1st trip into graphics. Most 3rd party addons/DLLs are of no use to me as the bank I work for is unlikely to allow any of those to be used in my projects.

I am using Visual Studio 2010 and have been slowly getting into threading. My current project has a form with a button that in turn starts two threads. The form itself has two labels on it that are used to display the progress of the computations. Each thread has a delegate defined to change the value of the respective label (as the labels are not defined in the thread, but on the form itself). The threads call subs from a separate class. All of the calculations work flawlessly. My problem is that the labels do not visually update. Through use of message boxes at the end of each loop, I know that the label text property is, indeed, being changed, but it is not actually refreshing and updating on screen.
My delegate code is as follows (I grabbed this code off of another forum where people had the same issue - it seemed to work for them, but not for me):
Private Delegate Sub UpdatePMLabelTextDelegate(ByVal s As String)
Private Sub UpdatePMLabelText(ByVal s As String)
' Are we in the same thread as the label itself?

I have a window form with a label. On the form I have a dataset, bindingsoure, and tableadaptor (all created by the IDE in response to binding the text property of the label) To fill the datatable, the IDE created this: Me.ClientsTableAdapter.Fill(Me.MyDataSet.Clients) Works fine. The bound field is a phone number, stored in the db as a 10 digit numeric string I need to format this with the standard ()-, and I have a function that will do just that. How can I apply the formatting so the phone number appears in the label properly?

I am looking for a code snippet which opens a image, creates a clone of this bitmap in memory disposes this opened image so that all handles are closed.
Usually we can open a bitmap using this[code...]
the following code however keeps the Image File locked until the application is running, any suggestions how to dispose it properly. (So that no handle is left open )
Things i already tried: use dispose method of bitmap <= doesnt work (need to write implementation)
Using Block also doesnt work.

'Displays Correct or Wrong in Labels
If ui1Textbox.Text.ToUpper = "FOOD" Then[code]....
I finally finished all my labels and textbox codes for this button.But now I have to code it so that I will be able to click the button and it will calculate all the wrong and correct answers in the labels and then finally place the percentage score in the uiScorePercentagelabel. What I dont understand is how to calculate all the different labels as one and then show the percentage right in the appropriate label.

I have been using vb6 for a while, I am following a tutorial by MS to develop a basic application and a simple task cannot be completed for whatever reasons! The tutorial asks to drag the label object from the toolbox and drop in the tab control container. Then, go to the label size property and adjust the size to some different dimansion. Basic stuff, right? It won't let me do it! After I enter the new dimensions (which by the way are not large or very small), the label size (both width and height) resets back to its original dimensions! I have the vb.net sp1 installed.

I am using a label to display a song for an mp3 player. I wanted to scroll the text inside the label for anything that is longer than the label width. I figured out the width of the label and if the width of the text inside the label is longer. But I have no idea how to turn this into subtracting parts/pixels of the text currently displayed and how to append the subtracted parts to the end of the new text.

I want to make the first number greater than the second because the numbers should be subtracted .

basically i need to change the text of a label where the name of the label comes from the value of a variable.So, for example,
Dim x as String = "lblTarget"
Dim y as String = "Target Text"
In this case the text of "lblTarget" would need to be come "Target Text". Basically, the label that is named the value of variable x would need to take on the text of variable y.

I am still a beginner programmer so keep in mind that what I'm trying to do is beyond my knowledge but I have no one to teach me Visual Basic except from what little I can learn off of the internet. Currently, I am using Visual Basic 2008 Express Edition so my problem may be appear different if I show you any of my code.
I've created a program that contains a label and the words in the label form a question. Below that is a textbox with some text that has to be memorize for a play. Just think of the question as the previous speakers part. So far I've set it so that the words in the textbox are randomly removed and are replaced with a blank. I face with the program is that the user can't enter the answer because the blank is in the way.
Instead of putting a blank where the missing word is I would like to have some textboxes put there that way the user can enter the missing word and so that I can later insert some code that will let the user check to see if the answer they entered is correct.now the missing word is still replaced by the blank so I need to get rid of that and insert the textbox wherever the words are missing.

Is there any way to detect if the text in a label is longer than the label itself (assuming autosize is set to false)? I want to trim the text in a label so the last line is a finished sentence (everything after that sentence is removed). I hope you understand what I mean.
I want to go from this:"Hello. This is a test string. Most test stri..."
to"Hello. This is a test string."
Is there any easy way to do this?

In the project�s btnReadNumber click event handler, replace the code in the try section of the try/catch block � the two if statements and the unconditionally executed code � with one if-else statement that performs the same tasks. Use the And operator to write the if-statement�s condition.What I don't understand is how am I supposed to use the 'And' operator so that when I insert a number between 32-16384 in the text box it'll allow it to go through and at the same time not allow any numbers lower than 32(lower_bound) and higher than 16384(upper_bound) to go through.I've use the 'Or' operator and that was simple, but with 'And' I'm not understanding it.Remember it has to be with the 'AND' operator. I bold the area where my problem is at. It's obviously not the right answer, but that's where I was stumped.
Dim sum As Integer = 0
Const upper_bound As Integer = 16384
Const lower_bound As Integer = 32

In my word processor I have an 'Open' option on a menu strip. Here is the code for it:
Private Sub OpenToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OpenToolStripMenuItem.Click
With ofdFile
.Title = "Select a file to open"[code]....
For some reason when I press the 'Open' item and open the ofdFile dialog box .txt files do not appear even when I have the 'Text Files' filter selected However, when I use the 'All Files' filter they appear. And the 'HTML Files filter is also working properly.Why are the .txt files not appearing when I use the Text Files filter?
