• .NET Development how to detect internet connection automatically

  i use this code to detect the internet connection but i need a better idea to get a notification as soon as the PC looses the connection and it will be silly to keep this code in a timer..

• .NET Development Help request on how to optimally link VC++.NET applications?

  Hi! I posted this question to a wrong forum earlier, now I am reposting it to the right forum. My problem is that I write C++ aplications in tradional form, e.i., the programs include one header file (.h) and one implementation file (.cpp). Compiling is going very smoothly. However, I get problems with the linker and most of the time I get the notorious LNK 2020 error, "token could not be found etc". The reason that I am getting this error message is that the linker cannot locate the implementation files and therefore cannot see where the "tokens" are implemented. It entails that you are supposed to load these .cpp files into the associated projects. My solution to this problem have been like this, because unti ...Show All

• Visual Studio Team System Question on merging through the API

  Hi, I have a small application that merges files between two folders. To do that I'm using the merge method of Workspace class This is the way I'm using the method: workspace.Merge(sourceFile,targetFile, VersionSpec.ParseSingleSpec( CSNumber, null), VersionSpec.Latest , LockLevel.None, RecursionType.Full, MergeOptions.ForceMerge); My problem is in cases that I'm trying to merge between two files That the change on them (ChangeType) is: Rename or Delete On these cases the application fails. There is a way to merge this kind of changes through this method – workspace.Merge Thanks in advance, Shmulik. What are you trying to do There's probably a better way ...Show All

• SQL Server Merge replication foreign key problem

  Hi there. I'm somewhat new to merge replication, and I've been having an issue with one of the scenarios that I've been trying to get working. I am using SQL 2005 on the server, with 2005 express on the client. I have 2 tables: Photo - which has a PhotoID primary key PhotoData - which has a PhotoDataID primary key, and a PhotoID foreign key both primary keys are int, and set to identity. I only want the Photo table to replicate for the merge, because I want the data in the PhotoData table to only be called by demand through a web service (since the images in that table are too large to be included in the normal replication). However, when a client adds a photo to his local database (which adds a record in the photo table, ...Show All

• Visual Studio 2008 (Pre-release) Recreating client proxies when in a Faulted

  This question continue the question on http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=727775&SiteID=1 Hello, We have problem with recreating our client proxy when it is in Faulted state. We have a stateful service which is configure for private session behavior. When our client start up it creates a channel factory and create a proxy for the client. It is vital that we will work with the same instance of the proxy because (as I understand) this proxy is "connected" (with logical connection off course) to the private instance on the service side. So I ask the question again: What is the preffered way of handling Faulted and Closed event of a client proxy I have experiment with WCF Faulted event and I ...Show All

• Visual Basic Data table only updates once...why is this happening!!!!!!!!!!!!!!

  Hi there, I have a dataset that i am updating during runtime of my program. To do this, I first delete all of the data in a datatable using "DELETE * FROM Table1" command, and then update the dataset. To initiate this process, i double click on a datagrid. The first time i double-click on the data grid, the program works exactly as planned--i step through the code and verify that first all the records in the datatable delete, and then is updated with all the new records. The problem i'm having is that the next time i double-click on the datagrid, the table doesn't delete! And then i get an error that i am updating a table with a non-unique record. If my table deletes like its supposed to, i shouldn't ever get this error.. ...Show All

Does screen require back end coding changes to change the columns. Also, where can you change the number of rows that show per page. Please Advise.

• Visual Studio Bug in debugger Edit value

  In the process of debugging a VC++ function, viewing the disassembly window, place the cursor on edx (the CPU register). Its value is correctly displayed in a tooltip as 0x00000800. Position the cursor in the tooltip, right click and select Edit Value. The starting value apparently changes to 0x0000080C. Further investigation reveals that what is happening is that the text in the tooltip has increased in length, and the final 0 is being truncated. VS 2005 developers: Either the tooltip length should be increased when the text length is, or the text length should remain unchanged. Thanks for pointing this out. I will add a bug in our database. You can readily do this too by visiting the MSDN Produ ...Show All
