Okay so I have 2 textbox's.
I made the first textbox to have a maxlength of 4 characters. Now after the user has entered 4 characters I want the program to automaticly tab to the second textbox.
I created a VB.NET web application project. Recently I got the dreaded above error message when a certain amount of web pages have loaded. On a form1_Load event, I do this:
vb Protected Sub form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles form1.Load
MyConnection = New SqlConnection
MyConnection.ConnectionString = CONN_STRING
MyConnection.Open()

If i have a computer that runs so fast such that it could make over 9e18 ticks per hour, when stopwatch.elapsedticks reached its maximum, does it resets itself or stays at Long.MaxValue?
View 6 RepliesMy form length is currently 1040 which when run displays as 870 and I use the vertical scroll bar to access the the boxes not displayed. I need more however, let's just say 1140 in length, but when I type that number into the 'size height' it only goes to 1044. Is there a way for my form to be the length that I need?
View 2 RepliesBelow is my gridview sample that retrieve a formatted html in my database..All i want to achieve is to limit the maximum length of characters i.e "50" then automatically create a pagination for the succeeding characters..to be posted in the gridview

I'm trying to fix an issue with an application I'm supporting (I didn't write the code). The code takes an SSRS report and renders it in pdf format. Users are sporadically getting the error indicated in the title. There is no rhyme or reason to when the error is generated (a particular report will run one time and throw the error the next).[code]
I read that the default length limit is 4MB. None of the reports by themselves are even over 350K. I'm wondering if this could be caused by a caching issue. I'm not an expert, so I need some guidance as to how best to solve the problem. I also want to understand why the issue is happening. Please note that only 2 reports are shown in the snippet - there are about 30+ reports in the full sub. I tried the proposed solution, but it didn't help (I also tried the Fiddler route, but did not see anything glaring). I thought it might be best to clarify. The reports will run fine for a while, but the execution time gradually gets slower and slower until the application eventually displays the error.
I see this error page appears in some client access but some client didn't see this.
View 2 RepliesI am writing a custom totaling method for a grid view. I am totaling fairly large numbers so I'd like to use a decimal to get the total. The problem is I need to control the maximum length of the total number. To solve this problem I started using float but it doesn't seem to support large enough numbers, I get this in the totals column(1.551538E+07). So is there some formating string I can use in .ToString() to guarentee that I never get more then X characters in the total field? Keep in mind I'm totaling integers and decimals.
View 2 RepliesWhat I need to do is find a string that can be any value, and is placed between ">" and "</" with a minimun length of 5 and a maximum length of 7 and contains exactly 2 dots.
So if I have a text file like this:
<a href="www.site.com">a site</a>
text<br />
More test<br />
[Code]....
I want it to find only the 5.0.77. And no, the number isn't always between h2 tags, and the number isn't even always the same. The only thing that is static about it is that is is between ">" and "</" and that it is between 5 and 7 characters and contains 2 dots.
I have a problem with my application "getting ahead of itself" what the problem stems from is i am manipulating a file and then using the manipulated file further along in the program, the trouble is the program is getting to the second step before the file manipulation is complete so i receive a file not found exception. The program that is doing the manipulation has an OnEnd sub routine and i have been looking at event handlers to try and figure out how i can hold up the application until the On End routine is fired. But i have been trying this to no avail, is there an example i can have that waits for an event to be fired?
View 17 RepliesMy code read a thousand files, and for each file a connection is made and open to check against a recordset in SQL. After 143 files, the application will stopped and thrown this exception regarding maximum pool size reached. What I don't understand is I'm closing the connection after every file is processed, could it be I'm doing it incorrectly?
Please see my code below. I was only able to make this work by setting max pool size = 3000 in the connection string, since closing the connection does not seem to work.[code...]
this is not working?

I'd like to be able to match a specific sequence of characters, starting with a particular substring and ending with a particular substring. My positive lookahead regex works if there is only one instance to match on a line, but not if there should be multiple matches on a line. I understand this is because (.+) captures up everything until the last positive lookahead expression is found. It'd be nice if it would capture everything until the first expression is found.
Here is my regex attempt:
@@FOO[(.*)(?=~~)~~(.*)(?=]@@)]@@
Sample input:
@@FOO[abc~~hi]@@ @@FOO[def~~hey]@@
Desired output: 2 matches, with 2 matching groups each (abc, hi) and (def, hey).
Actual output: 1 match with 2 groups (abc~~hi]@@ @@FOO[def, hey)
Is there a way to get the desired output?

Basically I am trying to get my timer to stop when it reaches a randomly generated number.
I have dimmed num2 as integer (num2 is timer)
I have dimmed num3 as integer (num 3 is random number)
I have done num3 = randNum.Next (0, 8)
My timer is working perfectly and counts from 0 -8. My randomly generated number works too, so how do i get the timer to stop when it reaches the random num?
I have tried;
if num2 = num3 then
timer1.enabled = false
But that didn't work
I have a field displaying on a datagrid that the user has asked to be variable length based on the data that is returned. Is there an easy way to determine how many characters are returned for a field and then converting that to a pixel length so that I can change the length of the field in the code.

If using the following in an if statement I get an error: If trg.Name.Substring(4, 6).ToUpper <> ("ABCDEF") Then I get the error: "Index and length must refer to a location within the string. Parameter name: length"
I assume this is because the string (trg.name) is too small for the 4, 6 substring. What would be the correct method of working around this problem? VB.net Studio 2008.
How do I continue to print a list onto another page once the bottom of the page is reached?

View 3 RepliesHow do you set the maximum number of rows allowed in a given DataGridView control? I'm using an unbound (meaning unbound to any data table) DGV to create a spreadsheet like entry. This is in order to allow the user to enter an array (80 elements). I can stretch the DGV into 80 columns and limit myself to 1 row or I can do 1 column 80 times. Either way, I need to limit the user to a finite number of rows...
