• .NET Development sharing of textfile (FileShare method not working)

  Hi guys, I'm working on application with multiple instances running in the same machine. In this application I'm accessing file "test.txt" and the other instances also needs this file. But the first application who will get to open the "test.txt" will have the write access and the other instances will only have read access. Below is my code snippet: if (singleInstance) {FileStream fs = File .Open( @"C:\test.txt" , FileMode .Open, FileAccess .ReadWrite, FileShare .Read);} else {FileStream fs = File .Open( @"C:\test.txt" , FileMode .Open, FileAccess .Read ) } When I tried running my application, I open the test.txt in the notepad and I can open it but can't do any mo ...Show All

• Visual C# Using a C# dll with a VB 6 front end.

  Ok, so here is my question. I was trained in C++ and Java, and have taken to C# rather likeably. My issue is that I am currently supporting a custom internal app that is written in VB 6.0. The plan is to move the app to a ASP.Net 2.0 platform, and thus my question. If I started developing a library that I could use to fix some of the issues with the current program, and wrote them in .Net (2.0 likely), and compiled a dll, would there be an issue with using that dll and the methods within in a VB 6.0 application I'm hoping I can move some of the business logic out of the application, clean it up some, and make it so it can be consumed by the future version of the app at the same time. TIA! You are in luck ...Show All

• Audio and Video Development Event Target

  Hi Chapter 8 of specification gives the larger picture of Event Processing. It says that user events are fist processed by the script and after that markup gets chance to process the event. eg if a user presses a navigation key then first the script (through event handlers ..if one is regestered ) first processes the gesture and after that (if allowed by script) the markup processes the gesture --changes the focus to the next element (depending on the navigation key). If the above is correct then this means the target for the keyboard events is always the current focused element. One exception might be access ( or shortcut) keys in which case the target is the element for which the short key is defined. ie script cannot override the acc ...Show All

• Visual Basic Modifying datagrid doesnot update the dataset

  Hi folks, I populated a Sql Server table into a datagrid using SqlDataAdaptor and dataset, which works fine. What I want to do now is to update the table when the data in the datagrid is modified.

• SQL Server SQL Injection prevention

  I am building my first ASP.Net app from scratch and while working on the DAL I came across the problem of SQL Injection. I searched on the web and read different articles but I am still unsure about the answer. My question is should I add db.AddInParameter(dbCommand, "AvatarImageID" , DbType .Int32, avatarImageID); Add in Parameters to my C# code to avoid SQL Injection. What is the best practice. I am unclear if the stored procedure already helps me avoid SQl Injection or if I need the add in parameters in the C# methods to make it work. I need some help.
