• Visual Studio Express Editions Directory searching

  Using: Directory.GetFiles(string path, string searchPattern) Is there a way to specify multiple file types in the search pattern What I'm trying to do is get all BMP, PNG, and JPG files from a directory without having to search the same directory three times to get all of the files.

Workaround : Get all the files from the directory and then compare each file extension ...Show All

• Windows Forms DesignTime licensing in a PopUp form which runs via verbs

  I have a Windows forms ExtenderProvider component that utilizes a form as a PopUp by using the verbs collection in a custom designer. Inside the PopUp form is an embedded 3rd party control which is used only on the PopUp form. My component is a dll and shows up in the TookBox from where it can be dragged onto a Form's component tray to add the new properties. The PopUp form is running via a service when the user selects it from the RightClick menu at design time. In the above context when my PopUp form is running, are its controls sited or is it considered a "standard" runtime form If it is running, is it still a DesignTime f ...Show All

• SQL Server Using UniqueIdentifier as Primary key

  Hello, is it a good idea to set an UniqueIdentifier field as primary key why i can't set an indentity specification How can i do Thanks a lot You can only specify an identity attribute for fixed precision data types and always returns an integer based value (i.e. non-decimal). For example int, bigint, numeric, etc. As for if it's a good idea to use a uniqueidentifier as the primary key, that's always up for debate, but you definately can do it. It will be unique, so that's good, and not only is it unique in the table, but also globally unique. Depending on how you are indexing the given column, you will find that the ...Show All

• Visual C# Passing arrays from unmanaged DLL code to c#

  Hi, I pass my dll the filename (string) to an image and it returns a list of points which are detected faces on that image. What I have done is pass a parameter from c# which is a pointer to an empty array. The dll code then allocates the array for the list of points and returns the size of the array. I then copy the array for use in c#. This does work - but is it the right way to do this (seems like a bit of a hack) If I wanted to pass a list of structs (instead of ints) back from the dll how would I do this see code below Thanks Ashwin ashwinv wrote: No i don't think so....as I am passing a reference ...Show All

• Windows Forms Windows Forms tip: use Spy++!

  I wanted to share a great little tip with all of you on how to debunk the inner workings of Windows controls. While .NET Windows Forms is a great library that makes creating forms very easy, there are limits to what you can do with Windows Forms. Luckily, it is just a wrapper around ancient technology, and we can still have a lot more control over the controls than you might think at first glance. Windows messages are still in the core of the .NET framework. I’m sure most of you have overridden a control’s WndProc once in a while.   One of my debugging techniques to see what is going on inside a windows control is to spy it us ...Show All

• Visual Studio Team System Manual Tests with Code Coverage for all assemblies

  Heya. I'm not sure I'm doing this the right way so I'll have to ask. I'm using Unit Tests together with Manual Tests and I'd like to view the Code Coverage information on these tests combined. The Unit Tests runs alright with Code Coverage but I'm not sure how I should run the Manual Tests to gather Code Coverage. Today, I just double-click the .exe in the bin/Debug folder but that seems to just collect code coverage information on the .exe, not the other .dlls. How do I go about running a Manual Test with Code Coverage Cheers, Chris Nope, you're not the only one who has this problem. The way coverage fo ...Show All
