• Visual Basic Inernet

  Using Vb, is it possible to download zipped files from a website, unzip them, and then use the files inside Steve it is. you can use either the ftp or httpwebrequest classes to take in the request, save the file then do whatever you want with the file. to extract the zip file, you can either "shell" it out using a 3rd party software or maybe use the Gzip classes/stream in .NET 2.0. here is a small example achieving the downloading of a file: http://www.codeproject.com/csharp/FileDownloadManager.asp gzip class: http://msdn2.microsoft.com/en-us/library/system.io.compression.gzipstream.aspx hope it helps! ...Show All

• Visual C# Modify the account for a Windows Service

  Hi, I've been asked to automate the installation of a legacy application. Part of the installation requires calling an existing EXE (not .NET, and no-one has the source code) that installs a service for the application. That all works fine. However, once the service is installed, I need to change the username and password that the service logs on as. Is this possible with .Net I can find no classes/methods that offer this functionality. I've tried to use p/invoke with ChangeServiceConfig from the Win32 API, but am not having much luck. Thanks Mick hi you can use 3 .net component to get full control of windows services. to add those component you should add components to your ...Show All

• SQL Server Setting Global Variables in a Script Task, HOW?

  I'm playing (and trying to learn)... I have an FTP task in a for each containter and am setting the RemotePath using an expression (works great). Thought I could use this to start learning some of the scripting funtionality in SSIS (in a script task) so found some code in this forum (thanks Original Posters!) and tried my hand at some coding... Intent was to create a variable and then dynamically overwrite the Expression in the FTP Task from the script (I know I don't need to do this, I just wanted to use it for learning purposes).... I have a variable named varFTPDestPathFileName (string) and want to set it to the value of varFTPDestPath (string) + varFTPFileName (string). Note: all variables are scoped at the package level (could ...Show All

• Visual C# Using a C# dll with a VB 6 front end.

  Ok, so here is my question. I was trained in C++ and Java, and have taken to C# rather likeably. My issue is that I am currently supporting a custom internal app that is written in VB 6.0. The plan is to move the app to a ASP.Net 2.0 platform, and thus my question. If I started developing a library that I could use to fix some of the issues with the current program, and wrote them in .Net (2.0 likely), and compiled a dll, would there be an issue with using that dll and the methods within in a VB 6.0 application I'm hoping I can move some of the business logic out of the application, clean it up some, and make it so it can be consumed by the future version of the app at the same time. TIA! Thanks for the r ...Show All

  I have coded an app that opens a word template, then populates it. I want to embed the file in the app so that it will be transferred during deployment. How do I do this, and how do I access the file once embedded Thanks DMan1, Not quite as simple as I had hoped for, but allright nonetheless. I've opted for just adding a folder to x:\Program Files directory and depositing the templates there. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Dependent Content Builds with Custom ContentProcessor

  So I'm trying to understand how to customize the content pipeline by building my own content processor for a fictional filetype (.tlf). This filetype is merely a list of relative paths to textures separated by newlines. Unfortunately, the sample in the docs only shows how to make a custom processor for something with no dependencies. However, thanks to our good friend reflector, I came across the BuildContent api in the ContentProcessorContext class. According to the docs, it can be used to (for example) "replac e the original TGA file references with new references to the converted texture files". This seems like the perfect candidate ... however, I'm not really sure what to do with the returned ExternalReference object which ...Show All

• Visual C# Bug in listview in VirtualMode windows Forms

  I want to create a listview in Windows Forms 2.0 with virtual mode. It works fine except a real bug. When I click an item in the listview in the event private void listView1_RetrieveVirtualItem( object sender, RetrieveVirtualItemEventArgs e) { } the e.ItemIndex is the number of VirtualListSize - 1 which in my case is 547. So VirtualListSize is 548 and the e.ItemIndex is 547. this is happening when I click any item in the listview like 2 or 3 or 12. What's happening It is a problem because: 1. The ItemIndex of the listview that I clicked is not the one that is comming in RetreiveVirtualItem 2. I use a Hashtable as a cache so that the listview will take its items in R ...Show All
