• Windows Forms help with deployment - mshtml.dll

  i've created a html control that refereces mshtml.dll. When deploying this project, it works perfect on all computers with vs 2005 on it (VS 2005 installs/registers mshtml.dll 7.0) However, whenever we install the program on a computer without vs 2005, it errors when rendering my HTML editor control because that computer doesn't hvae mshtml.dll 7.0. On the install, we register the dll, but it still does not work on anyone's computer. Has anyone worked with this at all any help would be awesome. thanks. That's correct. The one that came with VS2005 is for development purposes only. The end-user will still need to install the version of IE that corresponds to mshtml.dll version. ...Show All

• Visual C++ C++/CLI problems/issues

  I have some questions on C++/CLI issue. Let me explain my situation: I have an existing native COM dll that contains my logic. It has been tested and works fine with native C++ client using CoCreateInstance. I would like to add a new logic and notice that BCL has a class that I can use. So I add a new source file and header which I compile with /clr since I need to use one of BCL classes (actually, at this point, it is just an empty shell). When I tried to CoCreateInstance in my native client, it couldn’t create. But if I go back to my COM dll project and take out the /clr in my new source file, it works fine. After some debugging, I found out the problem and have been able to fix the issue. However, I would like to get more detai ...Show All

• .NET Development Doing Tape Backup in Managed code

  I hope I have the right Forum for my question .. I am trying to use Tape Backup functions in a mixed, managed and unmanaged, code. Since the Tape Backup functions have not been ported for use with managed code I have to call them as unmanaged code, unless someone knows of managed functions that do that. I am having a problem passing a handle, array<byte>^, for a buffer that receives the data from the tape to the ReadFile() function, the only one that I found that can read from Tape devices. The problem is in the 2nd argument, the buffer pointer, since ReadFile() is expecting an LPVOID. I tried using P/Invoke but the class MarshallAs has no such attribute as LPVOID. Any suggestions are greatly appreciated. Thanks. ...Show All

• Visual Studio Express Editions Retrieving Dialog Box Information Collectively Using Objects

• Windows Forms BindingNavigator Paging

  Hello. I would like to create a DataGridView in order to get only `n` rows at one time. The `need` for new rows should be triggered by the DataGridView. For example if the user gets to `n`-th row in the grid, then DataGridView should fire an event that will have an associated handler that would get the next `n` rows from the database. I've binded the BindingNavigtator with DataGridView and I've noticed that with the default toolbar items, at the end of the DataGridView, the `Next Item` button becomes disabled... Is there a way to handle that event Thanks. You can program your own navigation logic. But first set the MoveNextItem, MoveLastItem, MoveFirstItem and MoveP ...Show All

• Software Development for Windows Vista How to record from 'Wave' or 'Stereo Mix' in Vista?

  Hi all, I wrote the following question in other forum space but some MSFT guy told me to try this forum for my question. I hope I could get right answer as soon as possible here. On Windows XP or earlier, I could capture the audio stream to the speacker not from the external device (maybe endpoint device in Vista) like the microphone. In other words, D irectSoundCapture was able to capture from the selected recording device/source line in the Windows record control utility or mixerXXX APIs. And if "Wave Out Mix" or "Stereo Mix" or something similar was selected as recording source line, D irectSoundCapture was able to record the audio stream to the speacker. However, I could not find the way to do tha ...Show All

• Visual Studio Express Editions Filter to form2

  I am brand new to VB Express 2005 and only just getting starting to understand it. Here is my problem. I have two forms connected to a SQL Express database within the project.

• Visual C# Generics bug? Inheriting from a generic collection crashes my web server.

  Hello forum. Generics crashes web server hosting web service. Works in windows app. It is very easy to replicate, just copy paste code at the end of this post..
