• .NET Development How do you run javascript and vbscript on the same asp.net page

  When I try I get Cannot use 'javascript' because another language has been specified earlier in this page (or was implied from a CodeFile attribute). As soon as i declare a new javascript block <script LANGUAGE="javascript" RUNAT="Server"> This implies that there is already a script file specified above. If the line you declared looks like the following, make sure that there is a </script> tag associated with the line. If the closing tag is missing it won't allow you to add another script with a different language. <script language="vbscript" src="vbs_client.htm"></script> ...Show All

• SQL Server Linked Server GUI not working in SQL 2005 SP2

  According to the new features of Service Pack 2: "The Linked Servers node in Object Explorer now displays system catalogs and user database objects. As soon as the linked server is created, you can expand its node to show tables and views on the remote server." This works for all linked servers that are SQL Server based. But we have other linked servers that refer to a system DSN that links to Lotus Notes databases. When I try to expand the linked server to have a look at all the tables and views (as you can easily do in SQL 2000) I get the following error: "Cannot obtain the schema rowset "DBSCHEMA_CATALOGS" for OLE DB provider "SQL Server" for linked server "(null)".

• Smart Device Development XML Serialization

  ok so i have another question about XML Serialization on the smartphone. i am using Windows Mobile 5. on a desktop app i can put the [Serializable] tag above a class so it can be serialized. I am guessing that the Compact Framework has changed this a little because that tag didn't wor on my smartphone app. For my smartphone app i used the [XmlRoot()] tag above the class. I don't even know if this is the correct tag to use. The reason i think that it is is because i am able to serialize the class . but i can't deserialize it . here is the class that i am tring to serialize using XML namespace Timed_SMS { [XmlRoot()] public class StringSMSDateTime { //stuff } } here is the method that serializes a List of a class StringSMSDateTi ...Show All

• Visual Studio 2008 (Pre-release) Cache and Security

  Hi, I have read some posts about cache, proxy and ChannelFactory, but i don’t get a solution to cache the channels if i have to apply a membership user per call - If a use ClientBase, then i can not cache a client for every membership user. I have to cache a proxy for every user - Then, i implement a Manager to cache the ChannelFactory, then if i apply a credentials for every call... is it thread-safe to invoke the service with the credentials Thanks. Hi Pablo, I saw you are having problems with the number of open channels. Probably you can implement a token cache instead of a channel cache. You need to extend the ClientCredentials class in order to implement a token cache. I have impl ...Show All

• Visual C++ Memory leaks during using dll functions

  Hi there, i am using memory management functions of a dll. All I have are the header files for this dll. So, when i use for example dll_alloc_picture(X) and then forgett to use dll_free_Picture(X) the normal CLR memory leak functions don't help. Does someone have a suggestion how to cope with that, and maybe someone could give me a hint to the state of the art software for solving such problems.
