• Visual Studio 2008 (Pre-release) How do I utilize standard gzip compression for web services in WCF?

  Hi, I would like to compress the messages sent over a WSHttpBinding to get a better usage of low bandwidth. I'm primarily interested in compressing the response from the server and was thinking about utilizing the standard compression module for IIS 6.0. But this requires that the request has the "Accept-encoding: gzip" in the HTTP header and of course that WCF can decompress the response automatically, which doesn't seems to be standard functionality today. Is there any way to get this kind of functionality with WCF Are there any plans to make this decompression functionality standard in WCF (It is implemented in .NET 2.0 Web Servi ...Show All

  Hi, Our language service is COM components written by native code. We want to implement CODE SNIPPET. Someone have told us how to implement that function in MPF. But we can't use the languagesevice.dll file correctly in our project.

Could any one give us some advice Thanks. Best wishes.

• Windows Forms Inside datagridview - filter value of 1 combobox based on 2 combobox selected value

  Hi friends, Please note that both the comboboxes are unbound and are inside the datagridview. I have a datagridview with 2 comboboxcolumns - one showing the "category" and other the "sub category". Category and Sub Category are related tables - 1 to many.

• Windows Forms In the form designer I can't access objects which are on an other form.

  how can I access an object being declared on an other form in design time in visual studio .NET For example I have a grid on one form and I wanted to set its datasource to a DataSet table being on an other form. And I also wanted to refer to an image list which is also on the other form. But, I can't. I wanted to do it in design time! Can anybody help me Oh, All my objects are listed at the bottom of the page in the code view. They are private. I can make them public. So, the main deviation from other languages is the fact that the form components are declared at the bottom of the page, rather than the top. I guess this is ok. I'll a ...Show All

• Visual Studio Tools for Office How to get/calculate the character width in MS Word?

  BEFORE a lot of text strings are written to a Word file using Office Automation, I need to know the width of each string. Is there any way to do it Please note that office automation cannot be used, because the Word file is NOT available yet. Thanks. It's not really a VSTO related question, but besides that I think you are not in a position where you can determine the width of the string before knowing what font is used, the size of the font etc etc. Every font (except the fixed fonts) has its own width. A Verdana string can turn out to be of a different length compared to an Arial string. ...Show All

• SQL Server update query and determinism

  I receive the following error on an update.

• Windows Forms Application.ExecutablePath gives strange info

  Hi, I am trying to use the Application.ExecutablePath to find the executable path of my app and it gives me the following C:\\Programme\\Microsoft Visual Studio 8\\Common7\\IDE\\vctesthost.exe when running the debugger.  This is not what I was expecting. I was expecting the bin directory of where my application is built Is this normal Because you are querying this under a unit test, you are actually getting the application that is hosting the unit tests, in this case, VSTestHost.exe. There are some things that are hard to test and these are one of them.  I would probably abstract the Application.ExecutablePath into anoth ...Show All

• .NET Development Group Emails using Vb.Net

  I am somewhat new to designing .net applications. If someone can give guidance, would appreciate. I am trying to build a process where a user may enter on a web form various criterias that will pull data in from oracle db. Matching emails will be stored into a "job" that will sit on some scheduled server and have a separate process actually send out the emails. I'm sure there are many ways to go about this. Vikram, I've written a windows service that consumes a webservice to get the details of emails that have to be sent, just as you described.  The timer event fires and sends email ...Show All

• Software Development for Windows Vista WF custom persistence once again

  I don't want to save my workflows zipped in a blob field in one table like default SqlWorkflowPersistenceService does. It is not transparent and flexible approach, saved data contains class type information, making workflow evolution almost impossible. I would be a happy WF programmer, If someone explains me how to load/save workflow instances in different tables depending on the workflow class name, layout workflow properties in different fields, so I'd be able to make SQL-queries, and globally update my workflow definition using just new a new WF assembly and sql change script... Or somehow simulate this behavior using ...Show All

• SQL Server Problem connecting to SQL Server 2005 database instance

  I have an old ASP app that I have had to migrate to use SQL Server 2005. I have two pages that are virtually identical (one is edit only the other makes provision for adding new records - I didn't write these apps but I am responsible for making them work now). One page connect successfully to the SQL Server Instance and the other does not. They are using EXACTLY the same connect string. The only weird thing that has transpired is that we migrated to Active Directory recently. The ASP app that connects successfully was already on the web server prior to AD migration. The one that does not connect successfully was migrated after AD migrati ...Show All
