• Visual C# COM Object Problem

  Hi, i am having a problem with a COM object at work. Basicly the COM object exposes alot of interfaces, but for some reason, they are not all showing up on my machine. The COM Object is written in C++, and i am using VS.NET 2005, i have tried it on a colleage's machine, and it exposed all the interfaces, but it didnt on another colleage's machine. I have tried unregistering the DLL, and re registering it, and this does not help either. Any thoughts on this would be greatly apreciated. - SF Dont worry, we have managed to find the problem! basicly if you have compiled the COM object on the current machine, it generates another file as well, this file is required to build projects using the COM object, but no ...Show All

• Visual Basic Strange character problem

  Hello! I’m making a program which read quite large text files, and then converting them to .rtf documents to be read in for example Word. I ran into trouble the other day when a character couldn’t be read ( ) by my richtextbox object. I’m using the same function over and over, so I know it’s working, the problem arises when I pass a certain text file, or rather a certain string in the text file. When I do richtextbox.text = system.io.file.readalltext(tempfile), the readalltext() seems to interpret these characters as EOF, cause it stops reading even though there’s a HUGE part of the text remaining unread... The string looks like this if I open the textfile in Word: 0 96��321 Supposed to be 2 squares betwe ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. SpriteCache - A custom sprite renderer to eventually replace SpriteBatch. Source & Demo inside.

  Hey all, I put together SpriteCache for people interested in rolling their own SpriteBatch class. It's capable of doing almost anything SpriteBatch can do (no rotations yet), but also adds two nifty things: Per-Sprite Shaders - I know this is possible with SpriteBatch, but it's pretty obnoxious to have to set it up every time. With SpriteCache, you just set the effect and draw as normal. It's a lot simpler then setting up the effect passes every time. Four-Corner Tinting - I don't know why you can't do this with SpriteBatch, but you can't. SpriteCache allows you to tint each corner of your sprite individually. This is cheapest way to do 2D lighting. Play with the source and the demo and let me know what you think, I'd appreciat ...Show All

• Windows Forms foreach(Form f in AllformsOfApplication)

  Hi, searched the forum, found something that wouldn't work, so I'm asking for some help. I'd like to find all forms in my application after clicking on a menu item, so I can do something with all of them. That would be something like: foreach (Form f in AllformsOfApplication) { dosomething(f); } Note: not just the open forms like with Application.OpenForms but something like Application.AllForms (if only it would exist...)

• Visual Studio Express Editions Single instance application issues

  Following the code from this MSDN article: http://msdn.microsoft.com/coding4fun/inthebox/trickedoutapp/default.aspx It seems when I run the example in debug, it will only allow one instance of the application. However, when I run in release mode, I can run as many instances as I'd like. Here's my code, almost exactly the same as in the article: bool exclusive; Mutex m = new Mutex(true, "testProgram", out exclusive); if (exclusive) { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); MainForm mf = new MainForm(); Application.Run(); } else { MessageBox.Show("The application is already running!", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error); } I'd appreciat ...Show All

• SQL Server How to launch package from client machine, display progress and finally results?

  Please help. I'm completely new to SSIS, and I was hoping someone could point me in the right direction(s). I am developing a winforms client app, and I need to be able to provide the user with the ability to import data in CSV format into our application's database. I'd like to use SSIS if possible, as long as what I am trying to do isn't near impossible. I'm thinking of a UI where the user can specify a flat file (CSV) to upload and be processed by an SSIS package on a remote database server. This package will be responsible for validating the CSV file and inserting data into the database as appropriate. Is there a way I can: launch an SSIS package remotely, from a winforms app on the client machine that is not runni ...Show All

• Windows Forms Access to registry key is denied
