May 2, 2011I am not sure if I should put in a Text Box or not but this is how I thought it might have to go. Textbox1 shows the start time of a procedure and textbox2 shows the endtime of the same procedure. I would like it if the textboxes were in a 12 hour clock showing an am/pm tag on the textbox's. Then in Textbox3 it would show the differance between Textbox1 and Textbox2 in Hours and Minutes.

AxWindowsMediaPlayer - Current Position And Play Time Difference?
Jan 10, 2012I'm using VB 2010 Express with two instance of AxWindowsMediaPlayer in order to sync two videos (the videos are of the same thing but from two camera angles). Because the videos were started at slightly different times I've manually set the start time of each one using the following
AxWindowsMediaPlayer1.Ctlcontrols.currentPosition = 314.5093196
AxWindowsMediaPlayer2.Ctlcontrols.currentPosition = 237.1639908
The problem I'm having is that whilst the WMP clock initially displays the above times in each AxWindowsMediaPlayer, when I play the videos each starts a few seconds out from the stated currentPositions.
The video files are around 300MB each and when testing with smaller video files the problem does not seem to happen. I'm guessing the large file size is causing some delay and hence causing the problem.

Asp.net - Use Computed Columns In SQL Server?
Apr 9, 2012Question is the title itself. I was asked to use computed columns in SQL Server. But when I searched about it in Google, I found it was mainly for displaying the combined values of more than one coloumn. And usage of this may reduce performance if it is treated as a permanent coloumn. So I like to know
Advantages and disadvantages When and where we need to implement this. how can I achieve a solution for the below problem, if possible (with Compute columns. If not possible why?). Or any other way to implement this requirement. My requirement is to use a colomn which will identify which coloumn of that table was updated.So I can compare the values and identify the changes.

View 2 RepliesVS 2005 Missing Operand Error In Computed Data Column?
Aug 25, 2011I'm trying to add a computed column to a datatable that references another column in the datatable. Sometimes the computed column has a mathematical operation applied to it, but in this case I'm just referencing the original column. The code looks like the following:
ReportData.Columns.Add("1_1_US", _
GetType(Single), _
"1_1")
The code isn't actually hard coded as shown above - there are functions that return the values for the first and third parameters - but I checked those and they are returning the expected values and not generating any errors themselves.
The error is thrown when the .Add method is called, and the error states "Syntax error: Missing operand after '_1' operator." It seems to me that it doesn't like the column name, which I suppose I could change and just workaround it at the presentation level. Still, I'm curious. Is this a bug in the .net framework or something? It doesn't mind "1_1" as a column name in the datatable, so why is it having a problem with it in the expression statement?
Communicate Between 2 Programs Efficiently?
