I have this code
Dim replace As String = System.DateTime.Now.AddDays(7).ToString("yyyy-MM-dd")
What I'm trying to do is
Dim replace As String = textbox1.text.AddDays(7).ToString("yyyy-MM-dd")
is there a way to use that add days from a text or string value already?
I need code for a textbox countdown that will display text in a textbox in days.

I have a date in the future e.g. 13/10/2008 I need to subtract the current date (today is the 28/09/2010) minus 7 days, so thats 21/09/2010 minus 13/10/2008, which would equal erm, 720 something ? But the current date won't always be 28/09/2010, obviously. I need the code for this. EDIT: When i said future I mean past :)
View 3 RepliesI'm using visual basic 2008. I am done coding the CRUD... but i want it to have confirmation first. Then, i tried using panel, it works. but, my interface looks not organize. Is it possible to access the values in the text boxes from the other form?
For example: the client's information text box are on the form1 and once add button is click, the confirmation box will pop out. and the pop out box is in the form2. Is it possible to access the form1 text boxes from the form2?
So I'm attempting to get three variable to print in a string, but I can't figure out how to make the Concat or Join commands to work properly. I've tried assigning the strings to a defined string variable and then "concatting" that and trying to do it in one big line. I keep getting an error either way. Here's what I have so far:
Str1 = PaymentNumInteger
Str2 = NewBalanceDecimal.ToString("C")
Str3 = MonthlyIntPayDecimal.ToString("C")

View 3 RepliesLets say every 7 days you manually kick off a VB.net program that moves all old files to an archive zipped folder; and you run this same code every 7 days BUT at some point in time you need to go into that zipped folder and delete every file that is 100 days old........What would you suggest I add to the code I have now, that would automatically un-zip the file (I assume I do need to unzip it first) then do the delete of the files that are 100 days old or older? I am thinking I need to set a timmer or somthing to trigger in 100 days from now then reset it once it is triggered; am I on the right track here???

View 14 RepliesI'm getting the following error:
[ArgumentOutOfRangeException: Value to add was out of range.
Parameter name: value]
System.DateTime.Add(Double value, Int32 scale) +7657639

The line from which this error originates has the following code:
expires = Now.AddDays(30)
It occurs irregularly and irreproducibly. The server date/time is correct and set to GMT. I've heard that it could be some curiosity to do with timezones, but that is speculative. It seems that we're some time from the year 10,000 yet, so I can't understand why adding thirty days to the current time could cause this! Culture settings perhaps?
im trying to make a program, basically its a time in time out, i can get the date from my database and its in three columns, the first one is the date work, next is the timein and the other one is the timeout. im trying to convert the timein and timeout into date which are string at first but i having a problem when the timeout is the next day of the actual datework for example one emplyee has datework of 1/1/2009 and he time in at 6:00PM i can convert it to date and it work be datework + " " +timein or 1/1/2009 18:00, but if i add one day to the datework so the time out is correct "1/2/2009 6:00" , it wont work T_T is there a problem in my codes?
