Regions / Locales - String Not Recognized As Valid DateTime
Feb 5, 2012I've been having several problems lately with clients that are using a different Windows Region setting than I am. The error is as follows:
The type initializer for 'InventoryDataTable' threw an exception. ---> System.TypeInitializationException: The type initializer for 'InventoryDataTable' threw an exception. ---> System.FormatException: String was not recognized as a valid DateTime.
The error occurs when users load the application and their region settings do not match my own. The application loads up a dataset and attempts to receive a small amount of data before allowing the user to log in. When this is removed, the problem occurs immediately after the user logs in to the app. I cannot seem to find the proper settings to force the user to use either my Region, or to allow the application to figure it out on it's own...

View 39 RepliesLock A Folder In Professional Manner (without Using Encryption)?
Jun 18, 2011I want to lock (or completely hide without allowing to see with show hidden folder check) a folder with C# for windows platforms. This should be work for both FAT and NTFS file systems. I do not wont to use encryption since it is slow.
Also I need this as a robust solution so changing CLSIDs is not working.
Also removing permission with FileSystemAccessRule with AccessControlType.Deny also not working for me. Because that only work on NTFS and also if it is worked then user can right click the folder and remove deny AccessControlType.
Programmatically Utilize Textboxes In A Serial Manner?
May 13, 2012let's say I create a basic windows form with 100 textboxes, and create a variable that starts at 0, and counts up to 100. How could I pseudo-effortlessly have, for example, textbox7, when the variable is at 7, display a piece of text, instead of writing 100 lines of code such as
if vara = 7 then textbox7.text = "hello"
is there a way to utilize something in the nature of LINQ, where you could somehow say,
if vara = 7 then textbox & varA & .text = "hello"
this is just an example, I know it will not work, after paying a small bit of attention to the likeliness and possibility.....

Place A Video On An ASP.NET Page And Make It So That It Will Load In A Timely Manner?
Sep 28, 2010I have an .avi video (500 MB-50 minutes) that I embedded using the following code in VB.NET:
<OBJECT width="360px" height="360px" CLASSID="CLSID:6BF52A52-394A-11d3-B153-00C04F79FAA6" VIEWASTEXT>
<PARAM name="autoStart" value="False">
[Code]....
Worked fine except that it took approx 5 minutes to load. Converted it to a wmv file (cutting it down to 300 MB) and it started playing instantly while it download. Unfortunately there are some computers that will not play it for some reason. It will load and the timer starts up as if the video is playing but there is just a black screen. I ran some tests and determined that it's not a browser issue.
How can I upload a video that instantly plays on all computers?
Can Get A Specific Object Out Of List
May 23, 2010I have a number of custom objects of type X. X has a number of parameters and must be unique in the collection. (I created my own equals method based on the custom parameters to examine this) In each object of type x, I have a list of objects y.I want to add/remove/modify easily an object y. To write the add method, it would be something like add(objTypeX, objTypeY)I would check or the collections already has a objTypeX.If so: i would add the objTypeY to the already existing objTypeX else: i would create objTypeX and add objTypeY to this object. [code] Which collections should I use? I tried with hashset but i can get a specific object out of the list, without run down the list till I find that object.

Ranking Of List Items Based On Specific Property?
Feb 17, 2012I need to determine the ranking of the List items specified by one specific property of the items.
I have the following Class:
Public Class LevelA
Property items as New List(Of LevelB)
Public Class LevelB
Property factor as Double
ReadOnly Property rank as Integer
End Class
End Class
For example, let's say I have three items in the List. I have set the factor property for the first item as 5.50, the second item as 6.60 and the third item as 3.30.Now I should be able to get the rank property of each item (the highest value should be ranked as 1). Here the first item in the list should have the rank as 2, the second item as 1 and the third item as 3.
What kind of procedure is needed for the "ReadOnly Property rank as Integer" for returning such values? It should somehow be able to access the list in the parent class probably?

View 2 RepliesVS 2008 Finding A Specific Row And Specific Columns In Data Base File (Access)?
Jul 24, 2011I wonder if it is possible to find a specific row and specific columns in data base file (Access) . You see , I am using a DataGridView control to show only SOME of the columns (fields) of a table from an Access file . For example , lets say that in the DataGridView control I only show the following fields :Field1 , Field2 and Field3 .Now , when the user selects an entry in the DataGridView control , I want to insert the text from Field4 into a text box on the form .
The problem , however , is that I don't know how to get the specific row in the data base file and also I don't know how to get the text in column (field) Field4 of that row .One thing that might be important is that the index of the row in the data base file is not necessarily the same with the index of the current row in the DataGridView control . This is because in the DataGridView control the rows are order by the contents in the ID Field .ol .
