• .NET Development Memory consuming during BinaryFormatter Deserialization

  Hi, I have a problem and I need your help please, I have made a large aplication that takes a very long time to generate the results, so I have serialized the intermediate results periodically in a binary files using BinaryFormatter in order to save it from any suddenly problems like shutdown or restart. Now I need to Deserialize all saved files to continue my work. The size of the saved file is about 6.5 GB devided into about 260 files. When I try to deserialize it one by one, the first three files were deserialized in about one or two min. , and then the speed is very slow down, and the memory is fully consumed. I think that when the reading process starts the memory begins free and it then filled out with each reading ...Show All

• SQL Server Subscriptions invalid after SP applied

  Hello, I finished applying SP 1 to sql2k5. Under the replication monitor all of the subscriptions now look like [].databasename when they were originally [subscriber1].databasename. Under Mgmt Studio I see the subscriptions correctly. When I try and replicate I get the message "The subscription to publication 'pub_databasename has expired or does not exist." I have tried to reinitialize the subscriptions but it doesn't work. Is there a way to solve this without have to drop the subscriptions and add them again as I do not want to lose the changes that were made on the subscriptions. We are using merge replication. Thanks. John We have also come across this issue applying both hotfix ...Show All

• Windows Forms Auxiliary control missing in Recording Control

  I really hope someone can help me with a problem that has arisen when I recently updated my Realtec AC'97 driver. For reasons which are too complicated to explain I have two sound cards on my PC, one which I use for “normal” activities from a line-in and a dedicated sound card (Realtek) which I use to record LPs and audiocassettes for transfer to CDs. This sound card works through Auxiliary. Both worked fine- no issues. I could go into the Recording Control on Win XP and tick Line in or Aux as required. Perfect!! Now after downloading the updated driver the Aux option does not appear as an option when I go into the Recording Control for Realtek options. I have tried to find it via Control Panel, but with no luck. I have therefore bee ...Show All

• Smart Device Development Which event fires when Ok button is clicked?

  Hi, Does any one know what event is raised when i click on the close( i.e. OK) button of a form in a PPC application My app needs to perform different actions based on the way the form is closed. Basically, a form can be closed in 2 ways. First, by hitting the Ok button. Second, by calling form.Close() programmatically. In both the cases 'closing' and 'closed' events are raised.

• Visual Studio 2008 (Pre-release) Lots of ListView Items in my ListView = LAAAAGG....

  My program is quite simple really, but for some reason, when I have a lot of items in my ListView, the program hates my computer, and slows the whole thing down kinda. When I have just a few items in there, it works just fine. But, when I'm getting an array of files from GetFiles(path, searchpattern, alldirectories) or whatever, and am putting it in the ListView, where there's ALOT of files listed in there, which I might need in my program, it slows it down. There could be over a thousand files in that ListView. I really don't know how many songs I have. But, what could be the issue here I am using the latest .NET Framework 3 (downloaded like 2 days ago), Visual C# 2005 Express Edition, and I'm running on Windows XP SP2 (latest updates, e ...Show All

• Visual Studio Team System question about the trial version of TFS

  I installed the trial version to test it for a couple of weeks and TFS is not allowing me to add domain accounts to it. Is this a limitation in the trial At first i wanted to have the server as a standalone server and tried to add the users from AD to no avail. I then put the server in the domain that the users i am trying to grant access to are in. Still nothing I am getting the feeling that they are going to have to purchase the full version earlier than they expect to get the functionality out of it that they want. ...Show All

• Visual Basic "*" Question

  Hi again everyone, I am back once again working on a new project. For some reason I cant seem to find the info I need so, I am back here. :) Anyways, my project... I made a text file parser... it basically opens a text file of your choice, then it searches the document for any word you specify, afterwards, it places that info in a new textbox that you can save as a new file. What I really need this app for is to parse emails. Since the emails arent the same... just the same domain... I need to be able to use the * as a wildcard. Any info on how to do this would be much appreciated. Thank you in advance, Assuming you have an array of the text items from your list named TextArray: For Each SearchString As String In Text ...Show All

• Visual C# Misterious crash due to Listview, Bitmap & TabControl usage.

  Greetings, My application crashes misteriously when i access a tabpage that contains a ListView displaying thubmnails images. (See stack trace below) The exception agent displays the following message with an association line connecting it with the " Application .Run( new Form1 ()); " of my "main" routine:  "Parameter is not valid." It will only crash if, before i access the tabpage, the application's window is maximized. The listview is populated in the Form's constructor function. It uses the following simplified code: private void createThumbnails() { ThumbnailCreator t = new ThumbnailCreator (); Bitmap thumb = null ; thumb = t.GetThumbNail( "D:\\Documents and Settings\\T062948\\Des ...Show All

• Windows Forms "Foreign" msi files in a Setup project

  Hi there: Quick question: my application uses SMO, and I need to install that on the user's machine. I got the download from Microsoft in the form of a .msi file (the Microsoft SQL Server 2005 Management Objects Collection download from http://www.microsoft.com/downloads/details.aspx familyid=d09c1d60-a13c-4479-9b91-9e8b9d835cdc&displaylang=en ) . Is there any way for me to incorporate that msi file into my setup project I tried going through the prerequisites (I already have .Net 2.0 and Sql Server Express in there), but it is not dynamic enough to allow that. I could try and package the SMO assemblies one by one (the dlls were already added as dependencies), I'm just not sure how to force them to be installed in the correc ...Show All
