• Visual Basic Can't select folder of new project

  Can't select folder of new project If I select new project, the default is WindowsApplication1.  I rename it.  However, there doesn't seem any way I can choose where to locate the project.  I created a number of projects in my folder VS2005Projects, so there must be a way. I must have done something that took the choice away. I searched the forums for new project folders, location of new projects and a number of other variations, but there were no useful results. I must be missing something very simple. Can anybody help me dennist Mea Ahuz, as we say in Hebrew.  100%. Thanks. dennist (In ...Show All

• Architecture User Connection ratio for asp.net application

  I am designing a web application and using some underlying reader classes. I see the number of connections to database are much more than users, may be 5-6 times. I think the number of user and connections should be same or almost same. I ran some vanilla code with out underlying reader class and found out that number of user and connections are same(almost). Underlying reader class use type data set and extend reader class for type dataset for crud operations. I am not creating any thread or starting another connection and try to use the same connection and in fact uses same connection string. Regards, ...Show All

• Windows Forms Performance and Many Child Controls

  Hi, I have the need for a ListView like control (used in Details mode) that can contain one of several different child controls in each cell. I am using 9Rays FlyGrid as the ListView-like control, and placing a myriad of child controls into this FlyGrid and painting them over the specific cells they "belong" to. My problem is that the scrolling performance of this ListView window is horrendous. I have located the slowdown to the OnMouseDown method (Taking up to 1 second each time the scroll-down button is pressed) which adds up to multiple seconds quickly if pressed multiple times in succession, making it unusable. I a ...Show All

• SQL Server Can Sql Server 2005 and MSDE 2000 coexist?

  Hello All, Does anyone know if you can create a MSDE 2000 named instance on a server running full Sql Server 2005 (not Express) I have a need to run a program that will not port yet into Sql Server 2005.

• Visual Studio Team System VSS Converter error

  I've installed Visual Studio 2005 Team Suite and tried to migrate a VSS database to TFS but get message that VSS 2005 is not installed. I thought VSS was supposed to come with Team Suite If I recall correctly, the VSTS sku includes VSS, but it is not part of the default install package. If you do custom install and include VSS (or do a full install), that should do the trick (you can also run change/remove on VSTS from Add/Remove programs, and add VSS). If you try that and still get this error, reply back and we'll investigate further. ...Show All

• .NET Development Improving startup time - force cold start

  Hi, I want to work on one of my application's start up performance and to effectively do that I want to force a cold start everytime I start it to find out what takes really long the first time it starts. So how can I force windows to dump all the prejitted code that it generates the first time the application starts so it has to prejit again after the first start. Also, I was wondering what other techniques people use to find out what takes really long the first time the application starts and where one should start looking for bottlenecks Thanks, Tom I think this article from msdn-magazine could be inter ...Show All

• Visual Studio Tools for Office Call VSTO Addin functions from external application?

  Hi all, Please pardon me if this is not the right place. I'm looking for a way to call functions in a VSTO Addin from an external application. In VS2003 and Shared Addins, I used to be able to do this using this code in the external app: lole_object = iole_outlook.COMAddIns.Item("OutlookIntegrator.Connect").Object -- synchroniseAppointments() is a publically declared function in the Addin lole_object.synchroniseAppointments(ls_diarynoteIDs) However, when trying this using a VSTO addin, it did not work. From what I can gather after some research, this seems to be just the way VSTO addins are s ...Show All

• .NET Development Requests and responses use the same port number (80)?

  Hi,  If I send out 10 concurrent/simultaneous requests from a client to a web service, will the web service process the requests and send out the responses through the same port number (80), or different port number for different request What I observed is, IIS is using the same port number (80) to send out the response. Well, in this way, the problem is, won't this shared port be a bottleneck for the web service For example, I am sending 10 concurrent/simultaneous requests from a client to a web service. And the web service will send back the file specified by each request. If they all go through the same port, these 1 ...Show All

• .NET Development Collection to store result from multiple tables

  what Collection should i use to store result from multiple tables. I have to view resultset from multiple table in a gridview. I don't want's to return reader. I want's to return my collection in such a way that fields name are binded as column. It shouldn't be strong type collection Any idea. You should use a Dictioary<K, Dictionary<K,V>> or a List<Dictionary<K,V>> The first option is a little more complex, the second one is straight forward - it's a list of dictionaries or a list of tables as you call them. The K is the key you use to access the items in your table. The V is the type of the value stor ...Show All
