• .NET Development sharepoint 2003 webservices

  I want to use a webservice from sharepoint 2003. So I try to add a web reference to a sharepoint webservice. I looked on the internet for some examples and the show all the next location of the webservice: http://server_name/_vti_bin/name.asmx . But when I look on the server where sharepoint is installed there is no virtual directory _vti_bin. The asmx-files are in the directory C:\Program Files\Common Files\Microsoft Shared\web server extensions\60\ISAPI. Do I have to create the _vti_bin directory or is there something wrong with the installation Forgot to add the sitename to the url: http://server_name/site_name/_vti_bin/name.asmx\ Now the Add Reference button is enable. ...Show All

• Visual C# BreakPoint now working

  Normally, I store my source code on a network server. I have an app that i can run from this location. However, when I set a breakpoint in this app, it does not hit this point. But If I copy the source to my locale drive and set the breakpoint, it hits the point. Can anyone help with this. Thanks, Brian This might have something to do with the network share not being a trusted site. Because of this, .Net might be running the app in a sort of sandbox, where debugging is not possible. Could you try what happens if you add the network share to the trusted sites through your IE settings ...Show All

• Visual Studio Team System Warning 7 TSD312: The following dependencies are missing..

  I imported triggers which write information to a database which is different from the one I imported. How can I import multiple databases or have multiple data connections to avoid warnings like the one below: Warning 7 TSD312: The following dependencies are missing, and running the object may fail: How can I hide certain warnings such as TSD312. I click on a stored procedure which has a warning sign. However, in the warnings window the corresponding warning is not made "active". It would be nice if the tool would go automatically to the corresponding warning in the warnings window if a user clicks in the schema view on a schema object with a warning icon. Another sp has an error icon, but there are no errors in the e ...Show All

• Visual Studio Express Editions Several C# questions

  I have a couple of questions I've come across with this application that I'm writing, and I'm hoping that somebody here can help me out. Here's a quick background of what my application is ultimately supposed to do: There is an MDI Container window called MainWindow that can create MDI Children called ServerWindow which contain a connection to a TCP server. Based on information received and parsed over the TCP connection, the ServerWindow can create additional MDI Children, TypeAWindow and TypeBWindow. Here are my questions: 1. Can you give me a good example of how I should be setting up this TCP connection to be processed in the background The remote server sends it data without my application requesting it first (Asynchronously is the t ...Show All

• Visual C++ "unresolved external symbol _main"

  I am getting this error after I try to compile a visual C++ dll file. It compiles OK but when I try to build it I get the error. If you add to your CPP file a fragment like void main() { } then maybe the linker error will disappear, but I do not think the resulting file will meet expectations. Maybe you should re-start from a basic DLL project, generated by Visual Studio’s Wizard ...Show All

• Visual Basic populating tableadaptors in other forms

  Hello everybody, I have a problem with filling table adaptors on other forms but only when its not the startup form, this is my situation. I have 4 forms, 2 are detail forms and 2 are like search forms displaying all the records in a listbox and when you doubleclick on an entry in the list it populates the table adaptor in either form1 or form2 depending on which search form your clicking on, the problem is it only populates the tableadaptor if the main form is set as the startup form, it behaves exactly the same on whichever form is not set as the startup form. I have a messagebox displaying the ID number of whichever entry you click on in the same try/catch statement as the event and this works ok and seems to be ...Show All

• Visual FoxPro Interactive queries in an executable

  Does anyone have an easy way to give experienced users a “MODI QUERY” type capability inside of an executable without programmatically building it from scratch We have a client that is experienced in FoxPro and knows how to create queries using MODI QUERY from the command box. They have quite a few of these and use them to select data by changing the selection criteria in the query designer. In an old FoxPro for Windows module of the application (running as an app), we made it easier for them to run these queries by letting them put them in a directory that we read and used to build a pick list. When they selected the query, we would execute the MODI QUERY command inside of the app for them with the selected query. We are now upgrad ...Show All

• .NET Development Converting Access application to .NET

  I have an MS-Access application that needs to be converted to .NET. I know that there's an upsizing tool thru which I can convert Access DB to SQL Server 2005. Is there any tool to convert Access code to C# / VB.NET directly similar to converting VB6 code to VB.NET I believe there isn't as Access is different (VBA) than .NET. I could be wrong however but I am certain that you can't just "Convert" directly to C#/VB.NET - technology is different. What code is it you require to be converted from Access ...Show All

• SQL Server SQL Mobile create sdf file from SQL 2005 DB

  Hi, I'm trying to create a SQL Mobile .sdf file from my SQL Server 2005 database and cannot. I read the ms support docs for doing this and have had no luck . I created the respective publication and SQL Subscription for the db and when i run the process (not sure if i'm running the right process - docs don't say) it creates a directory under a "unc" directory with all my table objects (articles) with subscription/replication files for each table such as .cft, .bcp, .dri, .prc, .sch, and .trg. But no .sdf file for my SQL Server 2005 database. All I want is the .sdf file so that i can copy it to my Pocket PC device and then connect my mobile application to it. I want to copy my SQL Server 2005 database to my device so that t ...Show All

• .NET Development Data Relation Causing a Performance Hit???

  Hi Community I’ve been profiling a WinForm app based on .NET Framework 2.0. There are a number of hot spots from profiling, some of which are obvious and some not. One of the surprises that I encounter is that happens when you create a dataset with 2 data tables and form a data relation between them and remove it. All is fine so far. But if you do it again, it suddenly takes about 80s to create and remove the data relation. Here is the data collected using AQtime, sorted by the Time with Children in descending order. (Note that I disabled profiling during the first call of these methods as take negligible time) Routine Name Time Time with Children Shared Time Hit C ...Show All

• .NET Development Tcp Channel over load balancer

  I have a few questions about the TCP channel modifications in .Net 2.0 I want to use .Net remoting over a TCP channel through a F5/Big IP load balancer. I’ve gathered that all I need to do to achieve this (apart from using single call activation) is to add the following properties to my channel: socketCacheTimeout="0" socketCachePolicy="absoluteTimeout" Is this correct Should I add these properties to the channel on the Client side or the Server side (since these properties are TcpClientChannel properties, I’m guessing they belong on the client side) Can you point me to sample code that uses these properties I tried to verify if adding these properties does in fact ca ...Show All

• .NET Development Ping

  I've set up a server for an MMO i'm working on. Each client is connected through a TcpClient (the clients also form a linked list but this is irrelevant).
