• .NET Development Windows Form performance

  Hi. I realise that this post may be a bit general, but Im really after some hints/tips as to where to start. We recently took ownership of a .net 1.1 windows forms application. I have about a years experience with .net and about 6/7 with java awt/swing. This front end application was developed by another team and in my opinion, is very poorly coded. It is a direct replacement to a java awt gui and it makes exactly the same backend calls (through a web and j2ee layer) as the java application does. There have been various complaints about the performance of the app (its used internally by about 6000 people) and is perceived to be slower than t ...Show All

• Visual Basic How do I map a network drive in VB 2005?????

  Hello, I am making a small app and want to be able to perform some actions on a network drive based upon questions. I would like to be able to copy some files and folders, change the NTFS perms on them, and then open a specific text file, make some changes and save it. All of these things have NTFS permissions set for Administrator only. Since the application is to be ran by Non-Administrators I need to run the code with higher perms. I saw the impersonate command but the examples that I found were for asp.net and I didn't fully understand it. Below is a snippet of what I'm trying to run. Public Sub GetInc() Select C ...Show All

• Visual Studio Going from item list to individual items

  Say I have a setup like so: <ItemGroup>   <FooFile Include="*.foo"/> </ItemGroup> <Target Name="ProcessFoo">    <Exec Command="app.exe @(FooFile)"/> </Target> In this case app.exe can't handle multiple .foo files.  I need to feed those files to app.exe one at a time.  How do you do this in MSBuild Found it: You reference it like so: @(BooFile, ' ').  BTW, this is a great PDF resource even though it was from TechED 2004: http://supportech.insa-lyon.fr/Download/HOL/TechEd04/DotNET/MSBuild.pdf   If anyone has a link to a newer version of ...Show All

• Windows Live Developer Forums Sandbox for testing :)

  Hi, I didn't want to send out xml files, bugger my friends to play, or do polygamy, so I decided to create a Sandbox for multiplayer testing :) Currently it supports almost everything, except filetransfer, and the _NewEnum method of Users (how does it work anyway ) To test your app in the sandbox youu will have to do some minor modifications: First, do a simple search&replace replacing "window.external" with "GetExternal()" Next, add the function GetExternal to your script, steal it from one of the added test-games. Lastly, remove any unnecesarry headers, like doctype and meta stuff, somehow this f*cks up the script :P Currently, all I'v ...Show All

• Visual Studio Debugging BackgroundWorker threads

  This seems so big that I think it must be a something I'm doing/not doing. I have a main form with a BackgroundWorker. If I set a breakpoint in the background worker and debug then execution stops at the breakpoint. If I single step then execution resumes and doesn't stop at the next statement. More over, when I pause again the debugger shows the point of execution to be the top level Application.Run(...) statement. If I try to perform anything else on the thread then it reports that it is already busy. It certainly appears to have stopped running. If I just use break points then I think it can cope. Any ideas I co ...Show All

• SQL Server Maintaining Security

  I am a beginer in SQL Server. I have developed a simple accounting application in VB and SQL. Now I have successfully completed my application. Now I want to deploy it to my client. So I installed SQl Server and required VB components in the clients computer. I also created 'sa' login and secret password only know by me. I thought my data in that clients computer was full safe but later on i found that we can also connect to the sql server using the NT administrative account and easily change the data of the database. So now I am worried that if someone enters and access the clients computer with administrator's password then he/she can chan ...Show All

• Visual Basic Customize combobox index

  Is it posibble to give the items in a combobox a different index Meaning, maybe giving the first item the index 4 and the second item the index 7 and so on. Or is there another way to do this: Im reading some data from a database that contains a number (an index) and a name. Both of these should be in a combobox but only the name displayed The name is put into the combobox and when i select that name, the index that the name has in the database should be known also. No you can't, but you can insert an item into a specific index, here is an example : Dim Name As String = "MSDN" Dim Index As Integ ...Show All
