• Software Development for Windows Vista Windows Service Running Word via DCOM

  Hi everyone, I developed a Windows service which uses MS Word to generate documents. I call Word using DCOM / OLE. Up to now it worked pretty well. I tested the service on Windows Vista (Beta2, RC1, RC2) and it doesn't work anymore. Opening a Document in Word crashes with varying error messages. Office 2003 sais somthing like "Not enough memory". Office 2007 sais something like "type mismatch". I guess it might have to do something with the Session 0 isolation in Windows Vista. As services in Vista now have an own session. But I guess Word has problems with it's screen. In older Windows versions, Word worked "in the dark". When I run the service as console everything works fine. Anyone an idea w ...Show All

• Visual Studio 2008 (Pre-release) Linq to XSD: Casting Untyped Elements to Typed Variables

  Hi, I'm still just getting my feet wet with XLinq and I have a question. I have a framework that routes message parts to applications code after doing its own processing tasks. A message part is effectively a schema type, but the location of the message part in a given message is variable (or at least unknown by the apps code). Anyway, in .NET 2.0 our framework finds the relavent nodes in the overall message and passes either an XmlNodeList or an XPathNodeIterator to an application function. With Linq and XSD, I'm trying to replace the application signature with a typed variable like IList<urn.mycompany.customer.changedCustomer>, but I don't want the underlying framework to take a dependency on the imported schema.

• Visual Basic Setup Produced By "Build, Publish" Gives Error After I Uninstalled VB With CD And 'Removed' All Installation CD Programs

  Hello, I created a setup file from my application. I did this because I want to put my application on other PCs without installing Visual Basic. I basically want to just run the applicatoin on other PCs. What I did to create the setup file was within VB I clicked "Build" then "Publish." I then wanted to test the setup file on my PC, so I removed everything given to me by the VB installation CD! So, I uninstalled VB using the installation CD. But, I also had to go to the control panel to remove some of the programs that the installation CD gave me. I did this because the uninstall via the CD left things on my system that the installation CD gave me. When I was done, the control panel, remove programs listing ...Show All

• Visual C# Code conversion C to C# problem with bitwise << shift

  Please could someone tell me why the following code snippet in C# produces an error "cannot implicitly convert type 'int' to 'ushort' " on the bolded line public ushort [] table = new ushort [256]; public ushort XMODEMcrc( byte byt, ushort crc) { crc = (crc << 8) ^ table[byt ^ (crc >> 8)]; return crc; } This exact code works in C. I don't see anywhere where an int type is used Many thanks Les I'm guessing that the fact that there are literal ints in the statement might be casting the entire statement to int. Either way, this compiles for me: public ushort[] table = new ushort[256]; public ushort XMODEMcrc(byte byt, ushort crc) { crc = (u ...Show All

• Visual C++ Confusion with header includes

  Hey guy, Well I have recently just been exploring Visual Cpp and im sort of catching on but theres still a slight problem I run into with header includes. When I make a window form application I never now what headers to put in my programs for certain stuff. All I know is that for console applications you need the iostream include. Is there a list of header includes around here what explains the functions and procedures held in each one Thanks Keen. Hi Keen I would suggest that you get a very cool book called C++ Primer Plus, Fifth Edition by Stephen Prata. I am like you a C++ n00b but I have been finding this book of great help. It talks you through all C++ fundamentals and really makes sure you u ...Show All

• Smart Device Development Infrared remote capability with .net compact

  Hi, After researching infrared capabilities I can't locate how to accept incoming infrared signals from stnadard tv/dvd remotes to be able to play them back. I have seen and read plenty of articles eg. godotnet but can't seem to find what servicename or endpoint is required to be set in vb.net or c# to work with standard tv/dvd remotes eg. to associate with the client/listener classes. I'm starting to think that the .Net Compact Framework doesn;t support this capability and only embedded c++ will work I would be grateful for any leads.... Thanking you I've been on a long project about this, it isn't really possible im afraid (mainly due to 95% of devices not having the hardware functionali ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Day 1 - Where you at?

  So day 1 of the XNA madness has come to a close, with many more to follow. How far has everyone gotten on their first game projects I haven't spent nearly as much time as I wanted to on this, but I managed to get my head to bounce around the screen. I think the next step would be to add another head (i.e. angelina jolie) to bounce around. Maybe I'll even add collision detection so that if the heads hit, she says something like "I want you so much!" and I go "Yeah, whatever" and bounce. ...not sure if I should have mentioned the idea for this game...now everyone's going to steal it and make millions. But enough about my awesome game in the works. If anyone has anything worth checking out, upload it somewhere and post the link in this th ...Show All
