• Visual Studio Express Editions Industrial/factory automation.....is vbnet the way to go?

• SQL Server Datareader source/Data flow task property expression problems

  Hi all, I have the June CTP version of Yukon and it's various tools, and I'm having an issue with using property expressions or variable syntax within the SqlCommand string of a datareader source within a data flow task. It seems as if there were issues in past versions of doing this within data flow tasks, but I thought with the June CTP that this was a possibility. The documentation even states that you can do this within the sqlcommand property. Anybody else have this problem Any solutions Thanks, Adrian Crawford Mark, Thanks for your response.  I figured out my problem in another recent post here ...Show All

• .NET Development Policy settings

  Hi, Is it possible to apply policy settings(through policy file) in the DLL project. The DLL will be used by Windows form (client) application. I am having trouble doing this. I don't know how WSE runtime will find the policy file. Even if I set the file path in the app settings of DLL project then those settings cannot be recognized by the Main application. Is it true So DLL can access Web service but WSE settings can be applied on the calling application of DLL, or I have to do policy settings through code not from the file. Just want to know if this correct or if there is a trick available to apply policy settings through policy ...Show All

• Software Development for Windows Vista capture audio from microphone

  i am looking out for some help on how to capture audio...i made an application using directShow for video capture but dont know how to insert commands for voice capture..any sites u know..or any help do inform... I expect that your current code enums the video devices and connects the desired device to your output. To capture audio, you do essentially the same thing, except you enumerate audio capture devices. How far have you gotten And what is your output destination To select the microphone (as oppose to other sources), you should check out the IAMCrossBar interface. ...Show All

What are .dll files, and what are they for Grtz, Tom Yes you can create one  Start a new project of the type class library.   The class library can contain any classes which you might add to a windows project.  If you compile htem as a class library then you will need to add a reference to the dll in the project which is going to use the functions stored in the libary.  Then you can use those functions in the same way as the functions you create inthe project itself     ...Show All

• .NET Development Typed DataSet on two different table definitions

  Is is possible for a typed DataSet to update a table whose definition does not exactly match the DataSet, but that should be compatible with it For example: Our Address table originally had these columns: AddressLine1, City, State, Zip and the typed DataSet reflects just these columns. Now the Address table has been updated on the database to have a new column, AddressLine2 (Nullable). The dataset throws an exception when attempting to update stating that AddressLine2 is not in the table. But I don't care. AddressLine2 is nullable so I can safely ignore it. I cannot update the DataSet with the new table definition since I also need ...Show All

• Visual Studio Express Editions Express .img [Image] files cannot be burned to disk with Nero as stated !

  The webpage where you download Visual Express Beta 2 image files states that you can use Nero Ultra Edition 6 to burn these .img files to disk. This is incorrect. When I attempted to open any of these .img files Nero responded with an error message stating that the file format was incorrect. I haven't bothered downloading and trying Roxio as I really don't want to have to purchase two cd rom writing programs. Has anybody else come across this problem and what workarounds are there Note: these files open correctly in IsoBuster so there is no file corruption. Try ...Show All

• SQL Server DateTime with TimeZone ?

  Are there any plans to enhance the DateTime datatype to be able to store a timezone, and provide timezone aware arithmetic functions The lack of timezone support seems a glaring omission - especially given that Microsoft's biggest DB competitor (Oracle) has a timestamp with timezone datatype. At present, you have to code all this yourself in SQL 2005. Is this not something that should be built into the DBMS Thanks, Andy Mackie ...Show All
