I am using a label inside my loop to get a count on the number of records processed by the loop. during testing of the program I noticed that if I load a smaller Table( 1000 records) my label stops refreshing after about 110 and my mouse turns to an hour glass. The program finishes and the label returns the correct count when complete If I load a larger table (10,000 records) it works all the way through???

How to i display how many records that i have in a label on my main form for example if i had 3 table called Cusotmers, Orders, Products

How can I keep a label on my form with the current count of the selected rows. My DGV has a checkbox (unbound) and 3 other columns. When the user clicks on the row I want the checkbox to either be checked or unchecked depending on its status and update a label the is below the DGV to show how many rows are checked. DGV is FullRowSelect.
View 2 RepliesI am using the following code to create a dummy file of a specific size. RemSpace declared as a Long value and is returned in bytes from a separate function in my applciation. I have verified that it returns the correct # in bytes. However, when I execute the following routine, the dummyfile is created, but it never stops the loop. I have to kill it from task manager or it would fill up the HDD. The line:
For i As Integer = 1 To RemSpace
should tell the For loop to stop when it reaches the value of RemSpace, which is a long value in bytes. Here is my complete code.
Public Sub Create_DummyFile()
Dim RandomClass As New Random()
Dim RandomNumber As Integer

Is it possible to use 'Tab Stops' when you're concatenating (say) a Label text? I know it can be done for a PrintLine statement but I'm, trying without success, to put tabs after the colons in this code. ( "...... :" & vbTab ...)
Label1.Text = "Width margins:" & a.ToString & " Pixels." & vbCrLf
Label1.Text += "Height margins:" & b.ToString & " Pixels" & vbCrLf
Label1.Text += "Top margin:" & c.ToString & " Pixels" & vbCrLf
Label1.Text += "Bottom margin:" & d.ToString & " Pixels" & vbCrLf
Poppa.
I know I am missing the obvious. I would like a label to show how many cycles in loop are left.

View 3 Replieshow to count the lines in textbox1.text (with multiplelines). I don't need to count each character. I only need to count each line from top to bottom in textbox1.text (multiplelines) and I will use Label1 to display the numbers.
example:
1-pauljaones
2-tommyperrry
3-marktoms
4-Jonessmith
5-paulwhite
Obviously this is 5 lines and that's what I need to count.

I am trying to make a simple form that will display a count when the users clicks a button. I want the count to be readable as the program loops the math. So as it adds 1 + 1, 1 + 2, 1 + 3, ect... I want each loop to display in the label. Below is the basic code I came up with, but I can not figure out how put a delay of something like 100 milliseconds in the loop. The idea is for the slower version of the basic count console app you learn in school and I basically need to slowdown the math and display the sum as the loop loops.
Below is my code.
Private Sub xButton_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles xButton.Click
Dim xCount As Decimal ' Count
Dim xSum As Decimal ' Sum of loop
Do Until xSum >= 100 ' Limit the count
xCount += 1 ' Count by 1
xSum = xCount ' Sum = Count
xReadingLabel.Text = xSum ' Display Sum in Label
Loop
End Sub

View 1 RepliesI am having a mental block on how to work out a 15 minute timer that is shown on a label and counts down so that the user can watch it. I can do it just fine in seconds but I need to put it into the format of 15:00 and then have it count down the seconds and the the minutes when ever it drops 60 seconds. I found a few articles on using the dateNow syntax but that seems like it would only be good for adding time not subtracting it. Also I know I can set up a button to start and stop the timer but is it possible to use the space bar as the start/stop button?
View 5 RepliesI'm using a stored procedure in a sql database as the data source for a SqlDataSourceControl on my .aspx page. I'm then using the SqlDataSourceControl as the data source for a gridview on my page. Paging is set to true on the gridview. What i would like to do is set the text of a label to the total number of rows in the gridview. I can use this code
'labelRowCount.Text = GridView2.Rows.Count & " layers found"
to return the number of results per page, but it doesn't give me the total.
This loop takes forever to run as the amount of items in the loop approach anything close to and over 1,000, close to like 10 minutes. This needs to run fast for amounts all the way up to like 30-40 thousand.

I am currently building a search page, which includes a textbox and two drop-down lists, a search button, and a datagrid. If results are found and displayed, I would like a label to display:
(e.g.) "24 results found for 'blue sky clouds' "
...where the integer represents the results count, and the keywords and/or drop-down list selections are included in the string.If no results are found I would like the label to display:(e.g.) "No results were found that match your selection. Please try again"I would also like the label to be invisible until a search occurs.

As you all know, If the dataBase requires a numerical value then an error will occur when the user tries to insert the incorrect data type. With the code below after the user types in a value beside an int value type then it will go into an Loop through more than what is needed. How can I apply the same logic but allow the program not to check the 60 rows (I set the row size to 60). I want to break out of it if there are blanks ONLY if a row is blank and not for a black cell, because if the user leaves one cell blank then it would loop through the 'for each' for how many rows that they is. Initially there are 60 rows.
