Trouble preventing runtime compile of MyLib.XmlSerializers.dll

Posted By:      Posted Date: October 19, 2010    Points: 0   Category :.NET Framework

Hi All, I am using VS2005 on Win7 32bit to build a strongly typed class library that calls a web service. I've used the Add Web Reference wizard in VS2005 to add the reference to the service.

Everything works a treat, except the first call to the service takes 20+ seconds. Subsequent calls take around 40ms (as expected). Other clients (eg. SOAPUI) call the service very fast every time, so it's not the service.

I'm almost certain that the problem is the compiling of the MyLib.XmlSerializers.dll. But no matter what I do I can't prevent it from happening. I've set Project Properties > Build > Generate serialization assembly to 'On' and the file does get generated, but when I call the service a new version of MyLib.XmlSerializers.dll still gets compiled to the %TEMP% directory.

I've tried sgen.exe, again successfully generating the MyLib.XmlSerializers.dll, but still the first call takes ages and the file gets generated in %TEMP% on the first call.

I'm at a loss here and would be extremely grateful if anybody can suggest a potential solution.

Cheers, Leuis

Compile error when trying to use license.licx from 3rd party for a project using 4.0 runtime while t


I ran into a compile issue stating Error: "Mixed mode assembly is built against version of runtime v1.1.4322 and cannot be loaded in 4.0 runtime without additional configuration information" for a License.licx file from a 3rd party component included inside my Project I wanted to update to .Net 4.0

The problem was not in the license.licx file or the assembly, but lc.exe included with Visual Studio 2010 C:\<ProgramFilesFolder>\Microsoft SDKs\Windows\v7.0A\bin\NETFX 4.0 Tools\lc.exe

This is the exe that processes the license.licx file when compiling the project.

I needed to add support inside a config file in order resolve this error. So I created  a new lc.exe.config inside notepad and added this information then copied it to the same directory as the exe and now my license can be checked appropriately and my projcet can now use the .Net 4.0 Framework.

Create And Run Excel Macro At Runtime in C#

You've been tasked with writing a Windows Form application using the .NET Framework that interacts with Microsoft Excel. If you are new to working with Excel in .NET and are having trouble learning how to format certain cells or cell ranges, then this little tip will come in handy. Rather than scour the internet hoping to find the correct set of constants or method syntax for formatting your spreadsheet, use the built in tools in Excel to write the familiar VBA code for you. Then, you can paste the VBA code generated by Excel into the sample C# code below and run it dynamically at runtime.

How to Localize Windows Forms and Change the Language at Runtime

Localization is the process of customizing your application to a particular language, culture or locale. Visual Studio provides support for localizing Windows Forms with much ease. In this article, we will see how to localize windows forms and give the user the ability to change to his preferred language at runtime.
When you run a localized application, the appearance is determined by two culture values. The UICulture property is used to specify which resource files will be loaded for the form. The Culture property, on the other hand, determines how strings such as dates, numerals, and currency amounts are formatted.
Let us see the steps required to create a localized form. You can then expand this example and adopt the same approach for the rest of the forms in your project

Create new sql table at runtime VB.Net


I want to create a new table to sql database at runtime.  The column names would be "Name", "Date", "Event".  I would also like to have one more column name "Image" but the problem is that since the amount of images will vary, I want the application to count the amount of files in the Multiple fileuploader and then add a image column to the table for the respected amount of files. 

For example if i am uploading 3 files in the multiple fileuploader, the names should be "Name", "Date", "Event", "Image1", "image2", Image3"

I also would like that table name to be name dynamically from the textbox Name when the user enters the information.

I have the following code to make a new table, but I dont know how to name the fields at runtime like previously asked please help!!!

Hello good people, 

I have this beast as an error. Did my research and found some posts here as well but did not do any good for me.

.NET Remoting: Design and Develop Seamless Distributed Applications for the Common Language Runtime


Prior to the advent of .NET, DCOM was the underlying technology for remote communications between Windows-based applications. But DCOM is quirky to set up and configure and not as interoperable as it should be. In .NET, XML Web Services and .NET Remoting are a seamless and effective answer to the demand for tools to build distributed applications.This article provides a primer on .NET Remoting with insights into the internal plumbing. Important aspects of remoting, such as channels, object lifetime management, and clients for remote objects are discussed. In addition, some practical examples are provided.
