• .NET Development How can I continue after an error?

  Here's a good one for ya... I'm writing some code in a method that intentionally passes bad data to a series of calls in the method. The problem is, once the first error in the method is encountered, it jumps to the catch and then leaves the routine.  What i need it to do is to continue at the next item in the routine that is going to throw an error.  Since .NET doesn't seem to have Resume Next, is there any equivalent way to do this   Public Sub CauseErrors Try Error1(BadData) Error2(BadData) Error3(BadData) Catch End Try End Sub Hi, The problem you are facing is not a problem but it is the intended behaviour of Try... Catch block Structure your Try ... Catch in the follo ...Show All

• Visual C# Exposing soap functionality to c++ using c# via com...

  I have some legacy apps in c++ that need to make soap calls. Finding info on the best way to go about doing this is really tough. Moving the vc6 c++ code into VS2005 was not a big deal... but adding the web reference to the project just did not fly. The service I am trying to hit is an https... which seems to not be do-able as far a sproxy is concerned. After some examination I come to find out adding the web reference in C# seems to work fine. The proxy generation engine for the c# side clearly works better and there is the implcation it can handle and https call. ( not confirmed ) So I figure... ok... just make a com object in C# and call it from c++... however the learning curve on this little task is a bit steep... ( an un ...Show All

• Visual Basic Is string in start of other string?

  I need to know, how to find out if string 1 in in the start of string 2. Example: string1: test / string2:testing = returns true string1: test /string2: gettested = returns false Or you could do a comparison using the substring method dim s as string = "test" dim t as string = "test string" if t.substring(0,4) = s then '//This will be true end if Of you could use the left$ method (But this is older Basic method) if left$(t,4) = s then '//This will be true end if ...Show All

• Windows Forms combine datasets

  i have 4 datasets and i want to combine all 4 of it into 1 dataset..any help If you need only one table, I think you need add row by row according your logic, but I think add relations between tables would be more flexiable, we can add relations between tables in one dataset, code as follow: using System; using System.Data; using System.Data.SqlClient; namespace Microsoft.AdoNet.DataSetDemo { class NorthwindDataSet { static void Main() { string connectionString = GetConnectionString(); ConnectToData(connectionString); } private static void ConnectToData( string connectionString) { //Create a SqlConnection to the Northwind database. using (Sq ...Show All

  Just started the Direct X Part II (Part III) tutorial, and I seem to have an odd problem.

• Game Technologies: DirectX, XNA, XACT, etc. Why won't it accept the D3DXMATERIAL9 declarations?

  Ok, I recently started this project and it just keeps growing and growing. I had this portion of code working before, so I don't understand why it isn't working now. I am trying to load a mesh and use it to render to a simple Directx model (ship.x). After some brief changes to my computer (Hard drive data was corrupted and I reformatted and re-installed the operating system). Anyway to keep it short I have my project I saved and I was trying to get it working again. Its seems to compile perfectly except when it hits this section: dMaterials = new D3DXMATERIAL9[dnumofMats]; pSHipTexture = new LPDIRECTTEXTURE9[dnumofMats]; For some reason it doesn't recognize the objects: D3DXMATERIAL9 LPDIRECTTEXTURE9. I have come across this problem b ...Show All

• Visual Studio 2008 (Pre-release) Channel lifetime - best practices?

  Hi, What are the best practices (p&p) for opening/closing proxy.  Should I create proxy on my client and keep it open for all period of time, and close when client closes application, or should I open proxy, execute method, and close the proxy Keeping open proxy I need to specify inactivityTimeout="infinite", how good is that for server   What is that means, some sort of session is created.  How is that scale if I have load balanced servers Thanks a lot. Vlad. Hi Vlad, How often do you want to execute methods on the proxy Frequently creating/closing proxies can be costly. If you want to have high throughput (# of calls per second), you would want to cache t ...Show All

• Windows Live Developer Forums Error 80131502 when trying to load my add-in

  Hello :) I discovered the MSN Live Add-in SDK today, and I've been trying to play around with it a bit (in C#). I haven't been able to find ANY documentation for it whatsoever, so I've just been going off of sample code. I took a basic one (which ran and loaded fine, by the way), and modified it to its present form. The .dll builds fine, but when I try to load it in Messenger Live, I get: "The addin SmartTalker.AddIn.dll" could not be turned on. 80131502" ... and that's all! The code BUILDS fine, but doesn't load, and since I have no documentation, I don't even know where to begin looking for the problem.

• Gadgets Group Policy behavior: Turn Off User Installed Windows Sidebar Gadgets

  Hi, I've been looking at the group policy settings in Windows Vista for the Windows Sidebar. According to information I've found the policy "Turn Off User Installed Windows Sidebar gadgets" should behave like this: Turn Off User Installed Windows Sidebar Gadgets This policy provides administrators with the ability to block all gadgets not placed into the Shared Gadgets or Gadgets folders (in the Sidebar’s Program Files folder), both of which can only be modified by a user in the administrator group. Gadgets in the user’s directory will not display in the Gadget Gallery dialog or otherwise be allowed to run.
