DateTime dt6 = DateTime.ParseExact(strvalue.Trim(), "hh:mm", null);

message= "Error" i get the time vvale in strvalue.Trim() ,

I have been struggling with this for a long time. I have a form in which there is a textbox using an ajax calender extender. Now, the problem is that, I want to take the Date value which is string format and format it to a specific date format before inserting it into the database. The following is the core problem:Dim MDate as string=txtMeetingDate.Textdim d as new Datetime ' I want to convert the d to a datetime using the Mdate/// The problem is that I don't know what's the date format in the TextBox because users can use any time format they want, it is based on their windows settings!!!
So, I am struggling to change my String (MDate) into a DateTime in the same format the user have and then convert it into my format:"dd/MM/yyyy" and after I have the date in the correct format, I want to change it back to string and save it in the database.I am doing this so that I have the same dateformat saved in my database.
I have a column in a table within my SQL database that is specified as a time variable. Not DateTime or Date, but just Time. So, I need to know how to convert a text string into the format that would be accepted for entry in the Time column of a table in SQL. I know how to convert dates, but not time.

I'm not really much of a programmer but I've been working on something in visual web developer and VB...'ve got an asp.net page with a fileupload control and two buttons. One button is used to upload the file and then the other button does something else which involves accessing the file name of the uploaded file.
This is straight forward enough if you just use static text but I wanted to create a unique file name for the upload so thought about using a date/time value for this and delcaring it as a variable?This works great but how does the second button then access this file name? If I use the same variable name declared earlier it just generates a new one especially if mins and secs were used?
I'm not sure if that makes sense? But I'm basically wanting to create a unique file name for the uploaded file and then store that in a variable so it can be accessed by the other button? Without the variable constantly updating to a new ID?
i have two clock times in my DB as varchar datatype.. i loaded it from db as varchar itself. in C# i have assigned this value to a datetime variable.. how can i get the time from the datetime variable without changing it into a string.
View 4 RepliesI have a typical scenario that I'm struggling with from a performance standpoint. The user selects a value from a dropdown and clicks a button. A stored procedure takes that value as an input parameter, executes, and returns the results to a grid. For just one of the values ('All'), the query runs for roughly 2.5 minutes. For the rest of the values the query runs less than 1ms.
Obviously, having the user wait for 2.5 minutes just isn't going to fly. So, what are some typical strategies to handle this? Some of my own thoughts:New table that stores the information for the 'All' value and is generated nightlyCache the data on the caching server

View 2 Replieshow to suppress the "AM" in the gridview (template Bind("RideTimeMin", "{0:t}")? Don't tell me to use military time because the function is not "time on a clock"; it's how much time is allowed for a task (in this case the min/max hours & minutes that horses have to complete a 20 mile trail; e.g. 05:00, 05:27, etc). I'm currently accomplishing this in the "ondatabound" function by "..RTmin.Replace("AM","")". I have looked and looked at all the websites that talk about datetime formatting but have yet to find a way to do it upfront in the gridview bind statement.

View 3 Repliescan we grab a global variable or Session or View State variable in the javascript or using jquery?
I have a web application which uses a session variable to store the logged in userid. If no user is logged in, of course this variable will be empty and the contents displayed on my website are meant for guests. If there is a user logged in, the user specific controls/access/links will then be a displayed.
I am now having issues with my hosting where on shared application pool, the worker recycle is triggered every 90 minutes, this will clear sessions causing all my users to be logged out. I opted for a dedicated application pool, which got worse because I am only allocated 50MB memory limit and if this is reached, the worker recycle is triggered and I lose my sessions again. I have tried as much as possible optimization techniques, e.g. dispose where possible, close connections, disable viewstate for static controls etc but my memory per instance keeps building up from page to page without any signs of improvement. I don't use loops nor store huge objects like bitmaps etc but my sessions are now gone even faster than 90 minutes in shared application pool before.
I have considered using SQL Session State but there isn't a simple guide on using this with MySQL. I am getting desperate and considering using a public variable, a string as a replacement to store logged in user id instead of in a session variable. I am pretty sure this will solve my issue with sessions being recycled but are there any negative consequences of doing this? One problem I can think of is if the user closes the browser, the system will never know that the user is now logged out and this public variable should be nothing. In this scenario, will the GC eventually clear this abandoned public variable.
I'm evaluating two options of accessing a server side data on client side. Little bit confused about the efficiency or may be you can call it as finding best approach to do it.
I need to access a server side data may be an integer value in javascript on client side. I know about two options to do it.Create a public variable or property on server side and set it to javascript variable on client side as below:
var value = eval(<% =value %>);
Create a asp hidden variable and set value in this hidden variable from server side and access it through javascript using document.getElementById().
Which is the best approach and what are the pros and cons?

I am having text formatting problem with Outlook 2007 since it is taking different rendering engine i.e word 2007. In our application, we are sending mails to different clients who have Outlook 2003 and Outlook 2007. We have used CSS in our application for formatting.
1. Since I have created Tables and given width in Percentage to every <TD> but while rendering in outlook 2007, every table taking different widths depending on the no. of the columns. Due to this reason, formatting is getting distored. Outlook 2003 shows proper output.
2. In our aspx page, I have created DIV tag with Style attributes having Property as Display:none. But in Outlook 2007, DIV tag is visible. Due to this, unwanted Warning messages also getting displayed in the outlook 2007.
