• john1983lj Adding C# code to VB.NET 2003 project

  I have a VB.NET 2003 project. I have writtten a small code in C# and I want to add it to that project. I also want that when a Command Button on VB.NET Form is clicked, the C# code must execute. Any way Any link to illustrate the same. I think that you have to add it into a separate project in the same solution. You can then call the methods between projects. You will need to add a separate C# project to your solution, and than add a reference from the VB project to the C# project. Of course, the C# methods will also need to be accessible to callers in VB. -Tom Meschter Software Dev, Visual C# IDE ...Show All

• DroopyPawn Three questions regarding C# and .NET of today and tomorrow

  (I was pointed to this forum by Erik Jarvi after pestering him personally with these questions) Hi I have three questions regarding C# and .NET. I don't know if this is the best forum for these questions but here goes. C# question 1: Is there any possibility in .NET 2.0 to create a class that mimics the semantics of this: class A<B> : B { } It might look obscure but that doesn't stop it from being usable. Let A be a generic IDisposable implemetation that encapsulates all the tedious implementation details of IDisposable pattern and let the programmer just implement the disposing. If I had my_class which need to inherit from your_class. Let's say I need to add IDisposable pattern to my_class. Then if the above would ...Show All

If you don't want point units you can use one of the constructors tha ...Show All

  I have a dll that was made for C/C++ in Borland. The problem is that I keep getting an "entry point not found" error when I run the program. When I compile, I get no errors.

• Edgar Piraneque Unable to update the dependencies of the project

  I have had this error every time I try to check my program into source control after making changes. The project builds and works fine until I check it in and check it back out then it won’t build. I have deleted the setup project and built a new one only to have the same problem after checking it into source control. It also givs me a warning that " Assembly ' FolderName\FileName.exe ' is incorrectly specified as a file. Any suggestions would be helpful. With VSS unbound from the IDE I find the problem less likely but still occurs. I've also been able to recover by hacking about with the Hierarchy section in the vdproj file (confirming your findings that this is the part that screws up when things go ...Show All

• Tobey79 Why File Opens in Broswer Window

  i'm using .net 1.1. Can somebody try to answer this question http://forums.asp.net/thread/1357943.aspx View=Flat The way ASP.NET works is that when a post-back event occures (such as a button click), the page sends the appropriate data to the server, the server updates the form and re-generates the HTML and sends it as a response, and the browser reloads the page with the new HTML. In order for you to be able to change the button's state from the server, you have to do this. However, instead of sending back the page, you are hijacking the response to send your receipt file. There really is no simple way to "fix" this. I think you need to think about your whole approach here. For starters, wh ...Show All

• David Bridgestone Invoke a WebService automatically (using a Timer)?

  Hi, I have a small C# app that FTP's a file from a remote to a local server. The file it gets from the remote is available each evening at 2AM. Currently it is run manually (gasp!). I'm considering ways to run this automatically and would appreciate suggestions. I have the code running both in a Websevice and a Windows form. Since no one needs to see an interface for this app, I'm thinking of deploying the WebService..... I'd like the WebService to either run all the time (which seems excessive) or want to have it start around 2AM and stop around 4 AM (in case the file processing on the remote is delayed for some reason) How can a webservice be invoked "automatically" Create a Windows Service app that invokes it Wou ...Show All
