  I have an application that has been happily hosting the web browser component and sinking it's interfaces for quite some time now. I finally got Visual Studio.NET 2005 and, rather than getting to experience all the incredible new productivity gains, all I've been is hobbled by new backwards compatibility issues. Here is what one of my current interfaces looks like:        void ShowUI( uint dwID, ...Show All

• Yuriy T app.config for a DLL

  Hi all, I'm developing an add-in for Outlook 2003. My output is a DLL file which is hosted by Outlook. I'm using Microsoft Application Block called Updater which needs to read app.config file. The problem is that it gets the Office path and not the dll's. I tried to set: AppDomain.CurrentDomain.SetupInformation.ConfigurationFile = @"C:\Temp\AddIn\App.config"; But it didn't help. Any suggestions Thanks. Hi, D ...Show All

• Utkarsh Check if a path is a folder of file

  Hi! Simple question: Is there a way to find out if a path contained in a string variable corresponds to a folder or a file Using simply the string format, no.  A directory can contain all the same characters as a filename and vice versa.  The only way to tell is to actual check to see if the file or directory exists using either File.Exists or Directory.Exists.  If you need to determine this without going to the file syste ...Show All

  All is ASP.NET 2.0, C# I have a web service that works exactly as expected when on the host machine, invoked in a web browser.

• swfisher OOP and VB/ASP.NET

  OK, I asked this in a separate post , but I'll see if I can rephrase it. I'm trying to make my app more OOPish. My interface (that is, the HTML, the datagrid on it and the associated VB code) has objects that I want to expose to other classes & procedures. To do this, it seems to me that my interface should be its own class, which I instantiate once and then refer to from my core code. Where do I place this core code I on ...Show All

  Hello all; Is it possible to find a specific record by using Datatable.Rows.Find(), or i have to use SQL statement instead.

  I am programming in VB.NET (2005) I do not seem to be able to start process B from process A whilst process C is locked up waiting - as it happens - for process A to tell it that process B has started. From some other behaviours I am guessing that the new process B can not start while another process (C in this case) has not returned from processing a windows message. I think there is some way for process C to process m ...Show All
