• Windows Forms User controls

  I am currently a student on vb.net. I am creating a program that acts as a doughnut shop, the first user control identifies a selected customer id in a drop down box and shows the relevant customer details (name etc). The 2nd control i have is a datagrid that also needs to show the selected customers orders. The problem i have is the coding to get the two controls to communicate with each other, i need the first control to populate the data grid from the selected id. Any help would be great Many thanks Paul The drop down has an event for selected index changed. If you handle that event, you can then read ...Show All

• .NET Development Collection(Of Thread) - Store Thread objects problem

  Hello, I have been struggeling for days with getting my application to work. It basically allows a user to download a file from a website, stop/resume the download and various other options. My problem is that i create a new thread for each file in the download queue. To keep track of all the threads created i store them in a Collection for later use. Example: dim MyThreads as New Collection(Of Thread) Now let's say MyThreads contains 3 threads. Let's abort the work on thread 1 (0-2) = 3 Dim CurrentThread as Thread = MyThreads(1) CurrentThread.Abort() How can i create a reference to CurrentThread so that it can attach ...Show All

• Visual Studio Team System Sharepoint creation failed

  I have tried to read all the post on other reports of the same problem but I'm sure what helps. On my box (single server, clean Beta3 refresh install) ordinary Sharepoint site ceration works fine ( http://myserver/sites/test ) and checking the virtual server list shows the following: Name URL Version   Default Web Site http://w2k3server/ 6.0.2.6568   Team Foundation Server http://w2k3server:8080/ Not Installed Extend Could some Sharepoint "expert" tell me what to do before I do too much damage, Thanks Thanks for letting me think loud :-) I took the IIS road - and not it works - I'll create team project ...Show All

• Architecture Design Patterns

  What is the usage of common GoF design patterns in daily coding I ask this because as a developer I'm constantly trying to improve both my code and my overall design, to create software that's easy to maintain and easy to extend--- hopefully easy to change without effecting the 'client' aspect through the use of interfaces etc--- Is there a more straight forward application of certain design patterns For example, does anyone sit down and actually implement a bridge pattern in their code--- you read about it a lot, but only in academic articles, you equally read of people who find them absolutely useless most of the time... I don't think I ...Show All

• Visual Basic Debugger is extremely slow

  Has anyone else experiance really slow debugging in VB.Net Beta 2 Yesterday was the first time I used it to step through code line by line and I was shocked. It's a simple project with one form using a datagridview and it was horrible. We are talking a 3 - 5 second delay every time I hit the F10 key to step over...

• Visual C++ Converting Project to Use msvcprt.lib instead of msvcirt.lib

  I am attempting to convert a project to use msvcprt.lib rather than msvcirt.lib.   When I run nmake on the .mak file I am getting an error 'unable to open msvcirt.lib'.   I have removed all references to msvcirt.lib in the .mak file. The error is actually occuring at the linking stage, so it looks like the reference is inside an embedded library. As far as I know I have successfully rebuilt all libraries used by the application with msvcprt.lib in place of msvcirt.lib. I am probably picking up the reference to msvcirt.lib through an include file, which includes an include file, which ....    Any ...Show All

• Visual C# Abort sending email

  Hi there, my windows application offers the opportunity to send emails using SMTP_Auth. It works fine. I was just wondering if there is any possibility to abort the process of sending the email, once "System.Web.Mail.SmtpMail.Send(mail)" is executed. Imagine you send 20mb (which taked some time) and you want to abort. How can I do this Thanks, Finch82. As BJohnson said before, aborting the thread will not stop the request on the mail server. There must be a way, since every mailclient offers this possibilty. Thanks for any help, Finch82. ...Show All

• Windows Forms Application Icon

  Hello everyone;   I want to specify an icon for my application. To do this I addressed an icon to the application icon path by the project properties. However, it would be preferably to do this at runtime instead of design time. In fact I couldn’t find any property which named as icon derived from Application object. So how can I specify an icon to my application programmatically   A short code example would be truly appreciated. Thanks. Hi; Thanks for your nice reminder, That was helpful.

• SQL Server Stored Procedure being saved in System Stored Procedures

  We recently upgraded to SQL Server 2005. We had several stored procedures in the master database and, rather than completely rewriting a lot of code, we just recreated these stored procedures in the new master database. For some reason, some of these stored procedures are getting stored as "System Stored Procedures" rather than just as "Stored Procedures". Queries to sys.Objects and sys.Procedures shows that these procs are being saved with the is_ms_shipped field set to 1, even though they obviously were not shipped with the product. I can't update the sys.Objects or sys.Procedures views in 2005. What effect wi ...Show All

• Visual C# blocking 2 of the same exe's from runing

  im building a client/server application and I only want to allow the user to run one client per computer, what are some ways to block that 2nd client from starting up on a comp that is already runing a client thanks One of the best ways to do this is for your application to define a mutex that identifies your application to other copies of itself. Below is the code I run for this task: System.Threading.Mutex singleInstance; private bool AmIAlreadyRunning() { singleInstance = new System.Threading.Mutex(false,"MyApplicationNameMutex"); return !singleInstance.WaitOne(1,true); ...Show All
