Determine whether HWND is WPF-based window or native one

Posted By:      Posted Date: September 06, 2010    Points: 0   Category :WPF
Dear all The application I'm working on is targeted to share a window image. Given an HWND of a window, we use two approaches to capture it on Vista: native approach for native type of window - using BitBlt function, and Direct3D approach for WPF/Direct3D window which uses hardware for renderring. The question is, how to determing if a HWND is regular (so can be captured well with BitBlt) or is WPF-based or Direct3D-based, so Direct3D approach is needed to capture it. Is there a method to determin, which type of window the given HWND is? Regards, Marc

How to determine a set of months based on user entry in Excel?


How do I define a measure to do the following?


I have a base measure, [Billed Revenue], that I want to sum up across several months. The user will select a month in Excel. An Excel CubeValue function will call into the cube passing two members:  the month & the measure.


Most of my measures use PeriodsToDate. But this crosses all my defined boundaries. This set of months starts with the last month of the PRIOR YEAR & ends with the user specified month.

5 GridView Themes Based on Google's Personalized Homepage (igoogle)

One of the silly features I have found that I like about igoogle is how the pages color palette changes depending upon the time of day. So as the day progresses from morning to afternoon to evening the colors on the page change as well. Like I said, I know this is a silly feature, but I like it. And I have asked around a little bit and seems like other people like it to. To get a better idea of how the colors change, here are the background images from a few of the HTML elements.

dynamically adding sql server columns based on number of files in fileuploader


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!!!


Dim objConn As New SqlConnection("Server=<servername>;uid=<userid>;pwd=<password>;database=master")


Unique content within master page based on conditions met


 Hi all-

I would like to present users with unique content based on certain conditions being met as they land on the home page (default.aspx).  The condition logic will be in the VB code behind Page Load event. The content will go in a content placeholder as specificed from the master page. 

However, the content change wouldn't be something small (ie making a panel or label visible or not) but rather it will be different HTML,  Divs and databound gridview content.  The HTML content will be stored in the database.

Can someone point me in the right direction for best practices on how to accomplish this?

Image processing, determine white space and crop



I have created a image upload for our ID card system to allow users to upload new images, edit them and submit for approval.  This is all working well with a combination of asp.net (c#) and jquery to give a seemless editor etc.

We have had a few users who I cannot believe have scanned a photo of themself and then just submitted it with the A4 page of white and little photo.

I am wondering if anyone can help with a suggestion on how I could possibly reduce the load of these coming through (I can't believe they can be this stupid), it stipulates UK passport standards.

Would my only option be to check for a single continues colour that occurs and if it reaches a certain percentage point say 60% then to just send back an error stating they need to crop the image.

Can anyone help with providing sample or that I can use to move this one on.

I am still in disbelief on this one.  the other one is they take a photo of whole body and other in it and cut straight down middle chopping the people out but supplying a photo that no use for an id photo card....but that I can't imagine being solved programatically as I need to determine where their face dimensions are and what percentage of the actual photo is taken up by it and if it below a threshold reject it.
