Microsoft patch Windows by replacing the neccesary components. Remembver that Windows is made up of hundreds or thousands of individual files. When they release a patch it simply replaces the files that need to be changed. If your application simply consists of one file you will need to replace it, if it consists of multiple files, and you only need to change some of them then simply re-deploy the ones you need to change.

You will need to use some client side script to display the message. Javascript:
alert('This is a message from the developer.');
In order to know when a new user is added you will need to carry out some kind of polling because web pages are essentially disconnected (IE There is no way to recieve an event in an ASPX (HTML) page on the client about something that happened on the server). This can be done by either posting a hidden page back periodically, or preferrably using AJAX. The only other thing to consider is - does the user need to be notified immediately or is on the next page submit/change sufficent? If they can wait until they do something that causes a postback then you could check in each page load event (You may want to create a base class that does this and make all of your pages inherit from it).

It is supported in VB.NET 2.0, so you will be ok if thats what you are working with.

If you are not a liar then you can not make that statement. If you are a liar then you don't always have to lie, so you can make that statement. Therefore you are. You must be.... ;)

Enterprise services is simply another name for COM+/MTS. Basically this wraps all calls to objects within the COM+/MTS container in a transaction. So You write a DLL with a method (or several of course) and put it into COM+. All calls to the DLL will then be wrapped in a DB transaction. If you look on MSDN for Enterprise services you will find a lot of information on them. It is not really that complex from a development point of view, from what I remember you simply implement an interface or two.

Yea - roll your own and the keep it for use in other projects... LongHC - Yes you are, you must be... if your were not then you would not be able to make that statement.

If you are using the Datagrid then you simply need to set the column up as a hyperlink column.

I will work my way through those. Thanks Kevin - and to everyone else who responded.

Thanks for that Bob... Yes Memory allocation etc is something i have generally been able to avoid using VB and .NET. I will keep it in mind.

Ok, try the following code, then call the page with a string appended to the url after a question mark. For example "http://LocalHost/TestWebSite/WebForm1.aspx?ARandomStringThatIAddedToTheURL"
Dim sQueryString As String = ""
For index As Integer = 0 To (Request.QueryString.Count - 1)
sQueryString &= Request.QueryString(index) & "<BR>"
Next
Response.Write("Query String: <BR><BR>" & sQueryString)

Hi Again, Request.QueryString should help with your other problem. Can you keep the questions to the forum, rather than Emailing me directly please? PS: All of this can be found in MSDN if you have a hunt around. You may find it quicker that posting because you will be able to find it as required. Thanks, L

Hi There, I have developed an Add in / bolt on architecture in our existing VB6 app that allows .Net objects to be loaded/hosted and I have been able to debug the .Net code by loading the .Net project, setting a break point on the code that will be called by the VB6 app, then attaching to the VB6 apps process using VS.net. I have also done the same using C# as both the host and the add in. In both of the above cases it involves opening the add in project and attaching to the main project's/applications process using VS.Net. PS: You also need the PDB file to tie the source to the Exe/dll. Hope this helps. DL. MCSD(VB6/SQL7) MCAD(C#/SQL2000) MCSD(C#/SQL2000)
Yes I am very familar with OOP ;) Thanks for your response - I will take a look at this book. MCSD(VB6/SQL7) MCAD(C#/SQL2000) MCSD(C#/SQL2000)

Hi All, Sorry to post such an open ended question, but does anyone have an opinion on the best way for an experienced developer to learn C++? I have worked with VB6(Don't tell me - a toy language! ;P) and C# for some time now and I would consider myself to be pretty competent with both of these and SQL. I have also done a considerable amount of Web Development using ASP/ASP.NET and Javascript. Recently I did some reading on C++ and decided I would like to learn this too, however I am unsure where to start. A lot of the articles I have found start at a very low level - understandably aimed at novice developers. Does anyone have any suggestions/links/books that they would recomend for someone in my position? Thanks. MCSD(VB6/SQL7) MCAD(C#/SQL2000) MCSD(C#/SQL2000)
Presumably you have referenced the com object... Can you not just debug it, catch the exception and see what it is? MCSD(VB6/SQL7) MCAD(C#/SQL200) MCSD(C#/SQL200)
How does one go about becoming and MVP and what benefits does it incur?
You may also want to consider the IN Syntax if you have the full id: SELECT * FROM MyTable WHERE MyField IN('Value1','Value2','Value3')
If the strings are emedded into the EXE file then a redeploy will be required. If you have put them into an external resource file of some kind you could just re-deploy that, but I am guessing that this is not the case here.
