• Visual Studio Team System Merging Visual Studio solution/project files

  As much of the power of VSTS's new version control is the ability to merge all or parts of files across branches, I am suprised to be running into what seems to be a bit of a showstopper to my whole source control strategy. I have various 'project' branches that were created from a mainline (lets say at the same time), so that work on the same system can be carried out in parallel but in isolation. Both 'projects' make changes to the same solution file. At the point at which both projects want to formally release their work, they both need to merge their respective changes back into the mainline. The problem is that the sln file actually numbers each visual studio project that it contains and even has a count of the number pf vs proj ...Show All

• Visual Basic search string and return the following six characters.

  How would I best click a button and display the six characters that follow a specific part in a string. i would like to display in a label. for example search the above state ment for "button and " then return "display" to a label in the form. Thanks in advance!! you can either use Regex (regular expressions) as they are powerful and do good pattern searching but can be expensive (resources etc...) and may not be ideal for your situation. you can use some of the string functions like someString.SubString(0) etc...   now to obtain all text/string after a specific position:   dim myString as String = "button and display to an from and blah blah" ...Show All

• Visual C# linux application

  Hi to all, is it possible with visula studio to develop a compatible linux application and if i have to use DirectX sdk library wich is the best solution thanks Teo Hi, adding some words to Mark's post to say that the .Net 1.1 is fully supported under Mono and some of the 2.0 version is also supported. Version 3.0 is also being developed. There's also a project for cross platform managed graphics, but it's for the XNA framework.

• Visual Studio Team System How does this compare to other 3rd party applications that compare data and schema?

  What are the differences between this and other 3rd party applicatons that compare data and schema (eg. red-gate SQL Compare and SQL Data Compare) Thanks, Peter The main difference is that we integrate the schema comparison with our project and build/deploy model. Since there are not many different ways you can compare schema objects you will find not much differences. But there are some that I know of, for example the ability to deal with collation sequences in schema and data compare is one. I do not have a detailed list with differences. The main usage model for us is the comparison between your project and a target database. -GertD "DataDude" Developement Manager ...Show All

• Visual Studio 2008 (Pre-release) reliable messaging to the WCF service

  If I have a WCF service, (running as a windows service), that hosts the WF runtime etc to do its work, what is the best method of dealing with many calls to the service given that the WF runtime will have only 25 threads or thereabouts when using the default scheduler I understand that the WF runtime will just queue the instances up and will persist them if the runtime is stopped cleanly but that this could lead to large memory usage and long stop times. So, how should I manage this situation in a reliable manner We are likely to want reliable messaging to the WCF service but should I be using some queuing mechanisms of my own etc within my service I think you are talking about how to manage concurrent r ...Show All

• Software Development for Windows Vista In July CTP, using StateMachineWorkflowInstance to obtain CurrentState freezes workflows in that State

  Dear all, I have a working StateMachineWorkflow hosted under asp.net 2.0. I have written a simple routine (shown below) to interrogate the current state of a workflowinstance: public string WfCurrentStateDescription(string WorkflowInstanceId) { // Get the workflowRuntime which was started in global.asax WorkflowRuntime wfRuntime = (WorkflowRuntime)Application[WorkflowRuntimeKey]; StateMachineWorkflowInstance wfInst = new StateMachineWorkflowInstance(wfRuntime, new Guid(WorkflowInstanceId)); return wfInst.CurrentState.Description; } I find that, once I have called this on a workflowinstance, that instance gets "stuck" in the current state and never transitions to the next state, even though code appears to get c ...Show All

• Visual C# Passing values into EventArgs when a button is clicked

  I am currently building a shopping cart application using C # in VS2005 where there are 10 items to select from. There are 10 "Add to Cart" buttons, when clicked, will trigger a single method. That single method will either add a row (new item), or update the quantity (old item). In my existing code, i loop through each row in the DataSet to determine whether i should add a row or update a row. Is there a way to store the item information (name, description and price) in EventArgs so that when the "Add to Cart" button is clicked, the item information is passed to the single method using EventArgs I am aware that i can create my own EventArgs class that inherits the EventArgs class but is there any way to store my it ...Show All
