• Visual Studio Express Editions Combobox Databindings

  I am totally mystified by the workings of the combobox in the .Net environment. My problem is similar to that described by Johnathan on 25th Jan 2006 and replied to by Mattias Sjogren. Whilst Johnathan's original attempt was not the solution he used the following statement "foreach (String item in comboBoxCatagory.Items)" In order to try and get and understanding of how the Items are used I tried to execute the following: "foreach ( String str in SectorComboBox.Items)" and got the following error: Unable to cast object of type 'System.Data.DataRowView' to type 'System.String'.

• Visual C++ Native Code and Relocatable Memory Blocks

  Although I have found the new extensions to C++ in the 2005 beta to be thoughtfully designed, I am thinking about using old code.  I don't (usually) need automatic garbage collection but I would like to have relocatable blocks of memory in the application heap.  Is there an Easy way to use the OS to move blocks of memory that are allocated using "new"   Or alternatively, is there a Simple way that I can use gcnew to dynamically allocate blocks of memory that could then be accessed as if they were dynamicly allocated native arrays (similar to those that can be allocated with new)   I cannot fi ...Show All

• Visual Studio Internet Connection in VS 2005

  Hi,       I just installed VS 2005 on my machine, but my online help cannot be accessed. I keep getting the message: "The request failed with Http Status 407. Proxy authentication required". IE on my machine does have proxy authentication. Is there a fix for this   Thanks, Arshad Hmmm... not really.  We're using HTTP POSTs to make our web service calls.  Are you able to do HTTP POSTs (not just HTTP GETs) in IE to internet sites through your proxy   ...Show All

• Visual Studio Team System No effect of "define _CRT_SECURE_NO_DEPRECATE 1"

  For the moment I want to suppress all the deprecated insecure functions during static code analysis.  I've added this line in two separate files that get included in all source files: #define _CRT_SECURE_NO_DEPRECATE 1 to no effect -- the output still contains warning of these functions.  A colleague has resorted to #pragma to supress these warnings.  I'm curious as to why this doesn't work as documented in the help. Thanks. Sample warning: foo.cpp foo.cpp(18035) : warning C4996: '_wfopen' was declared deprecated c:\program files\microsoft visual studio 8\vc\include\wchar.h(827) : see declaration of '_wfopen' Message: ' ...Show All

• Visual Studio Team System Why is 'Drop' outside of source control?

  I'm sure a familiar site for a lot of people working with Team Foundation at the moment is a build machine file system littered with a folder after folder of previous builds in the drop location and it seems a bit odd that there is no provision for having the output of the build also placed in source control rather than clogging up the build machine, is there any particular reason for this So, OK, I could extend my team builds 'AfterBuildDrop' target to checkout the previous drop from source control and checkin the new one overtop and giving it a sensible label. I then want to be able at a later date to get against that label and publish to ...Show All

• Visual C# How do I test a button when running an event?

  I have a start button which runs a section of code continuously - how do I test the stop button while this code is running Colin, it is usually not a good idea to have an event executing for a long time, as while you are serving an event, the other events get blocked. This amounts to freeze the user interface. If you plan to have a lengthy task running in response to a button click, you should probably use a Thread, or the ThreadPool. It's fairly easy to use, and it's well worth the little time it takes to set them up, as the code becomes cleaner and easier to manage. Anyway, there is another option, ...Show All

• Software Development for Windows Vista How do I get the context of the workflow instance?

  Hi, I have a client sending an xml message to a SequentialWorkflow through a remoted service. The service exposes some methods which each triggers an event. The workflow has several Eventsink activities each “listening” to a specific event.   When the event is triggered from the service, the xml message is sent to the workflow through the eventargs and is also stored in a local service variable (System.Collection.Generic.List). I can use this service variable to access every processed message.   1. Is there any way to invoke the workflow instance to get my xml message directly from the runtime instead of s ...Show All

• .NET Development DataSet Usage - Not saving to file

  Ok, my knowledge of the DataSet object is elementary at best, but I'll try to make some sense. I've added a MS Access .mdb file to my VC# project using the New Data Source wizard. Incase it's pertinent, here's the connection string (sorta): Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|\db000.mdb;Persist Security Info=True;Jet OLEDB:Database Password=xxxxxxxxx Now, I want my program to count validate that there's at least one user account in the table 'Users' during startup. I'm checking this with [object].Users.Rows.Count , which works just fine. When the application inevidably discovers there's no accounts, I ...Show All

• Visual C# Question About Threads

  i want to creat form using thread but the form disappear i write this private void button1_Click(object sender, EventArgs e) { Thread T = new Thread(CreateForm); T.Start(); } void CreateForm() { Form2 f = new Form2(); f.Show(); } The Show method shows a modeless form, which means that the code that created it keeps on running. In this case, that means the thread ends. Your form should be a member variable, and you should probably just show it, and use threading within the form for any work that the form does. Or you could call ShowDialog, which would show a modal ...Show All
