Cut & Paste To Textbox Then Sql Server Update Takes Too Long?
Apr 20, 2011
I've written a small application that keeps track of my thesis notes and essentially I have a few textboxes for keywords, ideas and notes. When I type in the textboxes and hit my update button it works fine...when I cut and paste from a text editor into the textboxes and then hit my update button it takes way to long to return control to the form. Is there something I need to do to text that is copied and pasted into a text box before I send it to the database?

I have a client application that connects to a WCF service, i get the file size from the server as a long value then i convert it at the client to a string so it appears like ex:52.21 MB the application gets too many files sizes every time user changes the directory pathso the question is :should i convert the values to a string format from WCF service app then return it to the client as a string format or should i just return the size as a long value and let the client to convert it to a string format in other way which value take more bytes in the memory:

I'm using the following code to fetch a mac address
Try
Dim cls As New ManagementClass("\" & IP & "
ootcimv2", "Win32_NetworkAdapter", New ObjectGetOptions(Nothing, TimeSpan.MaxValue, False))
Dim col As Object
[Code]...
It is working as expected. My problem is that it seems to wait far too long for devices which do not respond, and when the output of GotMac is "The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)" How do I shorten the wait time for these types of events?

I am creating a WPF Application that uses Fluent library.
On my computer with Windows 7, 2GB RAM and AMD Triple Core processor, after double clicking on the program icon, The Splash image shows after about 1-2 seconds.
But on my brother's old computer with Windows XP, 512MB RAM and Intel Celeron 2.0 GHz Processor (Single core), after double clicking on the program icon, First, a process called PresentationFontCache.exe runs and it uses almost 100% of CPU for some seconds. And Total time is needed for displaying the initial Splash image is almost 30 seconds (or more).
I don't want that some users have to wait 30 seconds for displaying splash image and about 7-8 seconds for loading application. (my application load process takes 7-8 seconds)

I've been using VB for exactly a week today and for that past 4 hours I've been pulling my hair out! My problem is that our software can only run on one PC on a site, if two instances are running they cause issues. So instead of checking each PC individually I created a program with VB to do this (and other tasks) for me. The problem with the network search is that if I cannot access a remote PC (usually access is denied) then it hangs for a long time before moving on to the next. Can I introduce a timeout feature where the program tries to access the c drive but if it does this for more than 5 seconds and gets nowhere then it moves on? [code]'testcpath' is \pcnamec$ and the other two paths look for the software I'd need to remove if found. So basically, if I have access to every c drive it works fine and completes within a few minutes. If I don't have access to even a small amount then it takes an absolute age.

I'm trying to time how long an operation takes in Visual Basic (VS 2008) but its not working. the code I have is as follows:
[code]...
this is in an OnClick event, so what happens is that the user can click a menu item, and it goes and sends any changes it has to a database, and pulls down any new changes to a local data cache. This operation takes time, depending on how many changes are on the server and how many are cached locally. I've thought about making this a background task, so it doesn't draw away from the main app while it's running, but before doing that, I'd like to get an idea how long the operation takes. Since I can't exactly do a progress bar, I figured using the stopwatch would tell me how many ticks/milliseconds would occur between click, and when the "total synced" message comes up, but every time i run it and do an update the message always shows 0 ticks/ms. I don't think it's accounting for the delay, just from start to finish. Is there any way to make it so it detects a message popping up and times off that?

Here's the (Timer1's interval is set to "1" in the designer, and it is set to "Enabled" in the designer as well.)
vb.net
Public timeElapsed As Int32Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
timeElapsed = 0
Timer1.Start()
[Code]...
The issue is, timeElapsed always comes back as equaling 0, so fileCopySpeed always equals infinity. Also note that test.dat is a 100MB file. There's no way it's getting copied in under 1 millisecond!

I wrote an app in Visual Studio and is about 20k+ lines, but I don't know why it takes so long to start up. I have a splash screen just to test it to see if the program is working, and it is, but I have to wait for so long for the app to actually get to the start up form. A splash screen for this app isn't ideal, but was only using a splash screen for test purposes.

I am using the below code to get the local Administrator members, but this code takes about 6-7 seconds to execute. More precisely the "GetObject" takes that long.Is there another way to get the same information but faster?Also, where can I find what other properties the objects holds ? (To see what other useful information I can get)[code]

Whenever I publish my app, or when I run the exe from teh debug folder it takes a couple of seconds before the splash screen shows.However, when I run it from within VB (by pressing the "play" button) the splash screen shows immediately.
What could be the cause of this?

I have a small copy/paste type of program. You put text in the boxes, click copy and it copies it to the clipboard. I have a text file attached to format the text when it is copied. what I want to accomplish is...If I don't fill in every single textbox with text, I don't want that particular field to show when I paste it. Example, I have the layout like below on the text document.
textbox1.
textbox2.
textbox3.
No matter what, when I click copy, the text document is going to copy textbox1,2,and 3. If I only put text in textbox 1 and 3, I don't want it to copy textbox2 if its empty.

I've been working on a program that takes input from a textbox, removes the punctuation, puts the words into an array (using the split method), and compares the array against a reversed copy of itself to determine if it is a word palindrome or not. I understand the logic, but I'm getting kind of caught up as far as what code to us. This is what I have so far, but no matter what I enter into the text box, nothing happens. I'm completely lost as to what I'm doing wrong.

I have a problem when updating the source of an ASP ListBox in an AJAX update panel. When I set the source of the ListBox to a large dataset, I would assume it would take a small amount of time to render due to the number of items. However, when the DataSource is switched at run-time to a smaller set of items, it takes just as long to clear it. If you go from a small set of items to a small set of items this is lightning fast. Maybe I'm doing something wrong. I'm using the Visual Studio 2008 item template for an AJAX 1.0-Enabled ASP.NET 2.0 Web Application. I downloaded that from Microsoft.
Here is my code (Full source zip below):

I am running a test program for VB.NET, and it will simply crunch a million numbers in for loop. I've linked a variable implying the progress of the for loop with the progress bar, but it seems that when I run the program, the progress bar does not update itself. The bar itself has only value 0-100 as input (as stated in the document) and I've tested it without using the for loop, and it works.

I am performing a simple exercise of opening an SQL Server database connection, pulling the first record of a table from a DataReader object, and then closing the object. However, I have noticed that theres bit of a delay, about 5 seconds or so, in closing the connection. However, the delay only occurs after the command object executes the specified query. I've worked in a setup like this before and don't remember there being such a long delay while closing the connection. [Code] The connection closes almost immediately. What gives? I have narrowed it down to the where the .ExecuteReader line that causes the delay in the connection close. Whats causing the delay and how do I resolve it?

I need to write a program in VB 2008 express that takes an user entry from a textbox and strips out all the spaces, changes it to either all upper case or all lower case then checks to see if it is a palindrome. I must also include a loop structure and a decision structure. I have seen bits and pieces of code but I do not really know how to put them together. Basically I need it from the button click to the end. ?
