Web Forms :: Adding Subtracting Time In A Text Box?
Oct 6, 2010
I saw this thread but it doesnt quite cover what I'm looking for:[URL]I have two text boxes that will have a start time and an end time and what I want to do is to calculate the "duration" of the time between them while also accounting if a time starts before midnight on one day and ends on the next day (or any other day for that matter.) Then those values will be put into a SQL server database stating just the "duration."
I have two text boxes called starttime and endtime which are datetime sqldbtypes that I want to subtract the value to show in a duration label. I know that you can do a subtraction with datediff in t-sql to find the time difference, and I'm wondering if that's the best way to approach this. Here is the code from my default.aspx.vb page:
I have two text boxes starttimeInput and endtimeInput that have regularexpression validators to only accept input of time variables (11:00 am, 12:15 pm, etc) and then a durationLabel where I want to calculate between the start time and end time and present it to the user as minutes. I first convert the text to date and so I think I did that with the following:
i am having 2 textboxes on a form. What i need is if i enter some data in the first text box the same text should be displayed at the time i typed which means
if in the first text box i enter A the same text should be displayed automatically in the 2nd textbox.
I have 3 textboxes. In the first two, times will be entered (an IN and OUT time) and the third textbox needs to subtract the two times from txtbox1 and txtbox2. Somehow I need to validate the times are entered correctly into txtbox1 and txtbox2. Right now, if the first txtbox is blank, it brings in the system time in the following format on the code behind:
[Code]....
The txtTimeOut.Text box needs to be validated somehow to the same format of hh:mm tt and then the third txtbox should be the difference of the two txtboxes.
I have a table which has few rows. A row contain few textboxes, one file upload field and a dropdown list in its cells. I want to make it a dynamic table that is i should be able to add extra rows in table at runtime, but I dont know how to do it.
I have a 'Generate' button on form that does some file processing. It creates files, zips it etc etc. I would like to add some wait time (3-5 seconds) in the logic so as to complete the file processing logic. What happens right now is visitor clicks the button to generate those files and clicks another button to download. When they try download button many times the files are not created as in processing. So it fails to download. The only way I can ensure it does processing for longer period to allow completion.
I've been searching for hours trying to figure this out. I understand that somehow I need to recreate the control in page_load. I think seeing the code will let us better understand what I'm trying to do.
I have a session variable with year stored in it and in my if condition I want to check if the current year is one less than the year in the session variable like this:
[Code]....
This isn't allowed though. It says operator '-' cannot be applied to operands of type object and int. How would I do this subtraction?
Customers of hours buy packs of hours, these are credited and debited on their account. We have a prepayhours table and that has various columns in it, one credit and one debit. I have written a query using the Query building and SQLDS to total these columns, which is fine. What i really want to do is get that query, or if there is an easier way to add up all the debits and subtract them from the total of credits so you would end up with a + or - totalThen with that i can put it into a label or if there was a way to add a row at the end of my gridview which just said total in one column and the total of the hours in the next.
I have some SQL code which seems to work in SQL 2008 but not in the SQL designer for VWD.
CREATE VIEW dbo.prepayhrstotals AS SELECT COUNT(Debit) AS cntDebit, COUNT(Credit) AS cntCredit FROM prepayhrs GO SELECT (cntdebit - cntcredit) AS totalhours FROM prepayhrstotals
However, if I change the text of the LinkButton in the code-behind, I lose the image.
btnTest.Text = "New book name"
I have tried removing the LinkButton's controls in the code-behind and recreating the image along with changing the text, but it still doesn't work. I get either the image or the text but not both.
btnTest.Controls.Clear() Dim NewImage As New Image With NewImage .Height = Unit.Pixel(8) .ImageUrl = "~/DropDownArrow.png" .Width = Unit.Pixel(10) End With btnTest.Controls.Add(NewImage) btnTest.Text = "New book name"
How can I change the text in the code-behind and still retain the image as well?
I am working on an application, where a user will enter their primary information (Name, Address, Email, Phone etc), then enter their automobile information (usually a fleet of automobiles).
My web page currently has one row of text boxes (Car Make, Year, Model, VIN, Mileage, License Plate)
Below this is a button called "Add More Cars"
What I am trying to do here is allow the user to add more cars if they have more than one that needs to be registered.
My problem is how do I do this dynamically?
2nd problem, how do I collect the data entered by the user (for all cars), to be able to write them to the database?
I need to add Images in my Rich Text Box editor after a paragraph. I have gone through this article and it is very useful.
{URL] ....
But I have some question:
1. Can I add multiple images in this Rich Text Box.
2. After adding images and content in Rich Text Box, I want to save it in database. So where will I save images and content. I mean images in folder and content in database or both in database.
Is there a way to process images once uploaded to my asp.net site, to put a watermark or some text across the image to copyright the images? I would like to do this server-side if possible.The other option I have discovered here [URL] would be to store the images as they are on the server, but to manipulate the display so it appears the image is watermarked . However, this solution is in PHP. Does anyone know a good PHP to VB.NET translator?! Or does anyone have a good suggested link, idea or code? Or can I add PHP to my ASP.NET site?
I'm trying to add html text to some repeater items during DataBind, but the html text isn't parsed into controls it just displays as text. If I copy the text and just add it to the asp.net page it works fine so I know my syntax is fine. So is there a way to dynamically add more html text during the data-bind phase?
I have a textbox where data will be entered by user without any postback.

1 - How do I add a new e-mail in there set by textboxes in the webform ?

I was wondering how I would develop a page that allowed a user to type something into a text box that would show up in a label as they typed. I was looking for this online and found a few options but none of them worked. They included JavaScript, Ajax, and using the text box is onTextChanged command. For an example I need something similar to VistaPrint.
