• Visual C# Inserting a record using databound controls

  This seems like it should be simple.  I'm probably missing something obvious.. but here goes... How do I have a form for entering a new customer ( for example ),using databound controls on that form   I'm not opening a dataset to start with, so I can't just insert a record into that dataset. I suppose I could do a select saying something like "where customerID = -1" ( which would return zero rows ), and then insert a row into the empty dataset, but that seems kind of ugly. Is there a "right" way to do this    My appologies if this is a stupid question. Thanks, Kirk   Hi, See: http://msdn2.microsoft.com/en-us/library/ms233812(VS.80).aspx Thanks ...Show All

• Visual C++ Files paths withing VS 2005?

  I guess I'm not smart enough to figure out how to get the file path of a file opened inside VS 2005. With VC6 you could get a file's properties and there view the path. I guess Microsoft determined that wasn't usefull so its not in VS 2005. So is it possible to get the path of a file opened in VS or is a yet another thing that makes me wish I could go back to VC6 For files not part of the project, make sure you have this option turned on in tools-options-environment-documents: Show Miscellaneous Files in Solution Explorer. then just press ALT+ENTER while file is highlighted in solution explorer.  Or vote on these: https://connect.microsoft.com/VisualStudio/feedback ...Show All

  Hi: Does anybody knows why if one user is administrator of a site and edits a Word or Excel document, it opens as Read Only He is opening the document with the 'Edit with Microsoft Office...' but he cannot save the document, and it is necessary to delete and upload it again, and he has to do it every time he wants to modify it.

Both users were running Windows 2000 with Internet Explorer 6 (IE 6) in SPS 2003 e ...Show All

• Visual C# static method - Is there any workaround?

  I think most know we cannot declare a static anything in an interface. However, let's say I have this: public sealed class MyClass { private MyClass(string someText) { m_someModifiedText = someText; } private readonly static m_someModifiedText; public static MyClass Create( string someText ) { string modifiedText= ModifyText(someText); return new MyClass(someText); } private string ModifyText(string someText) { string modifiedText = someText; //do something to modify text return modifiedText; } public static string UsefulText { return m_someModifiedText; } } Now, this "sample" is just to keep it simple, but PLEASE just consider the concept rather than what the ...Show All

• Visual C# Find the right library at runtime

  Hello, Im writing a program that checks several company's websites for prices and compares them. Since every website is different, i have a different library with specific methods for each website. I want to be able to add libraries later on without having to change the source of my program. What i wanted to do was specify the library names in xml, use that to make an arraylist of websites, and use reflection to use those libraries. However, the program can't find the libraries unless i add the right reference before compiling. Is it possible to add libraries and use them without having to add a reference and recompiling my program Thanks in advance, Stijn I still haven't gotten this completely right... ...Show All
